Project Overview

Multi-award winner “Hope Rise” is a pioneering zero operational carbon and socially focused development of 11 homes for vulnerable young people who are at risk of homelessness. The development was designed by ZED PODS, an award-winning specialist modular contractor, to double up on the usefulness of existing assets and was erected on a metal podium 2.5m above an existing public car park, to retain 100% of the original parking spaces. Using precision manufacturing technology, the housing modules are completed up to 85% in an offsite factory and are installed on-site within five days and with little disruption to local communities. A year-long “Post Occupancy Study” by an independent body validated the as designed energy performance of the building.

Approaches Used

The super-insulated homes are fitted with low energy solar assisted air-source heat pumps and renewable rooftop solar PV, to complement the “fabric first” approach and dual aspect design. Electric car charging upgrades were installed to enable EV charging for all users of the public car-park, while connections to local public transport and cycling/walking routes to local amenities help eliminate the need for private car ownership. The Cross Laminated Timber (CLT) superstructure was manufactured and fitted out with kitchens and bathrooms offsite (in eight weeks) following Covid-19 protocols in the factory, before being transported to Bristol, where all the modules were assembled on site in three days. The use of CLT for all the one-bedroom homes also helped minimise the overall embodied carbon.

Key Sustainability Objectives/ Outcomes

This ground-breaking concept of erecting zero operational carbon homes on a steel frame podium over council owned carparks in city centre, is one way of bringing forward under utilised urban land to overcome the UK social housing crisis and create community living spaces using the very latest precision technology. The scheme is replicable globally in any city centre, reducing the need for development on green spaces and creating communities that are net zero in operation.

Analysis of the energy use has shown 104% of the annual energy requirement being generated on-site by the solar panels, making this development zero carbon in operation.

Lessons Learnt

The low-carbon technology installed in the homes was unfamiliar to both the residents and the council as the landlord. Despite ZED PODS going to considerable lengths to produce clear guidance for the residents, including a series of video tutorials, there was still some confusion regards the most effective operation of the controls. It should be noted the homes were completed and handed over during lockdown preventing one-to-one user training by ZED PODS. With a view to simplifying the operation of the homes, the residents were generally encouraged to leave the controls as they had been pre-set. Unintentionally, this hands-off approach left some residents feeling a bit disempowered when extreme summer and winter temperatures required them to make proactive changes (including opening/closing windows) to manage the internal conditions in their homes.

For further lessons learnt see the additional linked resources which include a Lessons Learnt report reflecting on the development process and the Post Occupancy Evaluation considering the first year of occupation.

The post Kintyre appeared first on UKGBC.

Project Overview

This project demonstrates how to design and build a PassivHaus as a contemporary English cottage. The client had outgrown their existing bungalow and they required an incredibly low-energy home that would cater for their current needs, whilst also preparing for the family to grow. Tate+Co worked in close collaboration with sustainability experts Etude to design a family home that would have the smallest possible impact on its environment whilst developing a carefully crafted, modern rural vernacular. A simple rectangular form and pitched roof take inspiration from the surrounding cottages and open the ground floor to the beautiful southern views across the fields. It was important to the client that suitable natural materials were used, therefore a carefully selected wood cladding was adopted, not just to clad the walls but also pop-out windows and the roof. Various widths of cladding board wrap the building to create a seamless, crisp finish. The brief was also to integrate state-of-the-art technology, including multi-mode smart lighting, heat recovery units and thermal stores, an air source heat pump and PV panels (soon to be installed). These were all designed holistically following a fabric first approach for the building to have the smallest possible impact on the environment.

The house sits on a quiet single-track country road with uninterrupted views of the surrounding countryside and is oriented along a north/south axis with the key areas opening to the south to flood the rooms with natural light and maximise the views across the fields beyond.

Approaches Used

An innovative split timber frame structure with Warmcel insulation minimises thermal bridging and increases the use of recycled materials in the build. An exposed polished concrete ground floor slab provides thermal mass, flattening out temperature fluctuations. A wood burning stove with back boiler connected to the thermal store allows the client to use coppiced wood from their land to heat the hot water during the winter. This along with an ASHP means that there’s no requirement for a gas or electric boiler. Wiring has been installed to allow the client to connect future PV’s to run the majority of the power in the house, including the ASHP.

Key Sustainability Objectives/ Outcomes

The brief for Kintyre was to create a certified 4-bedroom Passivhaus with low embodied energy.

The U-values are below Passivhaus standards which means no primary heat demand is required for space heating. A high-performance whole house MVHR system provides pre-heated fresh air whilst extracting warm stale air. An ASHP is used as the primary heat source for hot water via a thermal store, with a secondary wood burning stove also connected. The Energy Use Intensity is 20.9kWh/m2/yr. Kintyre runs on 100% renewable energy which has been procured off-site via Ecotricity.

Timber was sourced from responsible British suppliers, and Warmcel insulation was used which is a high-performance insulation sustainably manufactured from recycled newspaper. A new wildflower meadow has been planted along with approximately 120 new trees as part of the client’s desire to sustainably manage their surrounding land and improve the local biodiversity and wildlife.

The dwelling has been certified as a Passivhaus by the Passivhaus Institute in Germany.

Lessons Learnt

During the procurement of Kintyre, Tate & Co held regular workshops and design team meetings to make sure any design revisions did not have an adverse impact on the PHPP. During this process suggestions were made to improve the detailed design to help minimise thermal bridging and help with air tightness. One of the challenges was the timber frame and foundation detailing, this was overcome in conjunction with Etude who helped form the split timber frame structural detail that improved the U-value of the external building fabric.

Larkhall Park https://ukgbc.org/resources/larkhall-park/ Mon, 31 Oct 2022 16:53:57 +0000 https://ukgbc.org/resources/larkhall-park/ The social value delivery approach of a residential development in Larkhall, London.

The post Larkhall Park appeared first on UKGBC.

]]>

Project Overview

This case study is featured in UKGBC’s report, A Guide for Delivering Social Value on Built Environment Projects.

Larkhall Park involves the creation of 127 new homes (flats and townhouses) and flexible community and commercial space. The project stemmed from significant involvement from local community groups, particularly Friends of Larkhall Park. In 2014, Lambeth Council were forced to cut their maintenance costs for green spaces across the Borough. In response to this crisis, the Friends of Larkhall Park approached the Council to explore whether some underused and neglected council assets could be used to build a community-managed maintenance approach for the park. The project proposes using three council-owned sites adjacent to the park to build high quality, sustainable social housing, and additional community space for local groups. As part of the planning application, Homes for Lambeth commissioned Buro Happold to produce a social value measurement framework for Larkhall Park.

What makes the project interesting?

  • The role Friends of Larkhall Park play in the project, particularly the influence they hold over design decisions and the sustainability strategy.
  • A community engagement specialist, Locality, were commissioned to do the ‘on the ground’ engagement and interact with the local community to ensure the strategy was in line with community needs.

Future considerations: 

The measurement framework is set up to track social value delivery through design and construction. The design team and client will review the targets at each design stage and identify any challenges and opportunities going forward. As this scheme will remain within the ownership of the client, social value creation strategies will be carried forward post completion into management practices, particularly with regards to the local park and the community space.

Approaches Used

Buro Happold have developed a social value framework containing qualitative and quantitative KPI’s. To develop the framework Buro Happold:

Identify priority internal stakeholders

  • Identified internal stakeholders such as Homes for Lambeth and the Friends of Larkhall Park.

Understand stakeholder needs

  • Conducted a Local Needs Analysis using local reports and national and regional data sets (Step 3). The Needs Analysis focused on the following five topics:
    • Historical context
    • Geographic context
    • Local and regional urban policy, regulation, and ambition
    • Economic profiling of the area (employment and economic activity, economic sectors, household income
      and housing affordability)
    • Social profiling of the area (demographics, housing type and tenure, social infrastructure, and community facilities). The key objective of this exercise was to map out other assets and initiatives surrounding Larkhall Park that already provide social value to the local community.

Identify priority external stakeholders

  • Revisited the initial list of stakeholders and updated it to include external stakeholders whose needs were prioritised during the Local Needs Analysis.

Agree social value outcomes

  • Held an internal design team charrette, where the design team and client were presented with the results of the Local Needs Analysis and given the agency to express their opinion on what doing the ‘right thing’ for the project looked like.

Create a social value delivery plan and put in place a social value measurement framework

  • The results of the design charrette were translated into a set of KPI’s and a tracker that was agreed to by the client and allowed the design team to feedback how they thought the design was responding to the social value framework ahead of planning.

Understand stakeholder needs

  • Locality were then hired to carry out community engagement with the previously identified local groups to confirm local stakeholder best interests and opinions, allowing Buro Happold to validate alignment with the social value strategy KPI’s and desired outcomes

Key Sustainability Objectives/ Outcomes

Social Value outcomes:

As a result of the community engagement carried out by Locality, the following social value outcomes
were prioritised for Larkhall Park:

  • Children and Young People
    • To provide a safe, stimulating, and inspiring space for children and young people, through, for example, sports, arts, intergenerational activities, playschemes, early years and pathways into work and enterprise.
  • Climate Challenge
    • To support activities and measures to address the climate challenge, including up-cycling/circular economy, gardening, food growing, library of things and bicycle initiatives.
  • Enterprise and Employment
    • To support local residents into enterprise and work and support remote working including start-up support, managed workspace, business advice, networking, and links to local business opportunities.
  • Health and Wellbeing
    • To promote health and wellbeing amongst local residents, through for example, non-medicalised social prescribing, sports and wellbeing activities, healthy eating, support groups, counselling, and therapy.

Lessons Learnt

Engage with the local community groups as soon as possible because they can be incredibly insightful and can inform the structure of the social value strategy for the project. Understanding the numbers through socioeconomic baselining is important, but so is, and perhaps more so, the qualitative picture you get from engaging with local community groups. Having a dedicated consultant for that that can feed into the strategy was really valuable for this project to validate the proposed aims and strategies.

Yorkhill https://ukgbc.org/resources/yorkhill/ Mon, 31 Oct 2022 16:27:43 +0000 https://ukgbc.org/resources/yorkhill/ The social value delivery approach for the mixed-use development plan for the closure of Yorkhill.

The post Yorkhill appeared first on UKGBC.

]]>

Project Overview

This case study is featured in UKGBC’s report, A Guide for Delivering Social Value on Built Environment Projects.

Since the opening of the Queen Elizabeth University Hospital in June 2015 several NHS properties across Glasgow have been declared operationally redundant. The resulting consolidation of NHS facilities will result in Yorkhill Hospital, the former home of the Queen Mother’s Maternity Hospital and the Royal Hospital for Sick Children being permanently closed.

The impending closure of Yorkhill, and its prime location by the River Clyde, has seen it become a prime candidate for development. The initial development proposal produced Michael Laird Associates (with support from AECOM and JLL) promotes a mixed-use development masterplan incorporating the following:

  • Significant amounts of new public realm that will be linked to the existing context and site surroundings and will provide a distinctive and active pedestrian environment that will encourage social interaction and local spending within the masterplan area.
  • A series of new and engaging pedestrian accesses through the site making valuable connections to the North, East, South, and West.
  • New commercial frontages along Old Dumbarton Road with a suitable scale to ensure a vibrant new street edge is created. To inform the masterplan, JLL developed a toolkit that will be used to assess and report the socio-economic value of proposed development options against the project’s priority social value outcomes.

What makes the project interesting? 

  • The bespoke socio-economic toolkit helped to focus the design process.
  • The potential socio-economic contributions of Yorkhill are being discussed alongside more traditional economic contributions such as construction value.

Future considerations: 

The Yorkhill masterplan is currently awaiting approval. However, prior to the final approval and implementation of the masterplan a solution to the relocation of the residual clinical services remaining on site needs to be determined. This revaluation of clinical services will be considered in terms of the initial outcomes derived from the toolkit and will support the evolution of the masterplan.

Approaches Used

Identifying priority stakeholders

  • Prior to commencing work on the toolkit, Scottish Futures Trust had entered into early stakeholder engagement and a review of local, regional, and national strategy.

The information gathered during early engagement and the results of the strategy review were used to develop a draft list of potential socio-economic outcomes for the site (Step 4). The list of socio-economic outcomes was then used to create the toolkit.

Understand stakeholder needs

  • Data for the Anderston/City/Yorkhill ward (Ward 10) was used. Where this was not available, data for Glasgow City has been used. When ward or Glasgow-specific data was not available, Scottish averages were used.
  • A hierarchy of data was established to ensure the toolkit is robust. Data from Scottish Government and the National Records of Scotland (NRS) and contracted sources (such as ScotCen) were first-choice data sources followed by other official sources, such as the ONS, and third-party research from credible sources such as The Red Cross and the Trussell Trust. As much as possible, data from recent years was used.
  • As often as possible, the toolkit compares data from Glasgow to that of the Scottish average, or that of a UK or Great Britain average.
  • To spot trends and track progress, data was plotted over time.

Put in place a social value measurement framework

  • Based on the data, recommendations were made on the changes that can be made to the existing Yorkhill masterplan, as well as the construction, detailed design, and operation of the completed project.
  • A bespoke report on the socio-economic context of Yorkhill with a full explanation of the socio-economic contributions and how they apply to the site and local communities was presented.

Key Sustainability Objectives/ Outcomes

The toolkit focuses on the following socio-economic outcomes:

  • Employment
  • Education
  • Greenspace
  • Gross Value Added
  • Accessibility
  • Safety

The post Department for Transport – Floodwater Management Grant appeared first on UKGBC.

]]>

Project Overview

This case study is featured in UKGBC’s report, A Guide for Delivering Social Value on Built Environment Projects.

The town of Clun frequently experiences flooding incidents which adversely impact the local community. In response, Shropshire Council have been allocated funds from the Department for Transport (DfT) to develop a flood alleviation scheme in Clun in collaboration with WSP and Kier. A comprehensive data collection and initial project scoping phase has already taken place, with a technical note on the scheme delivered in July 2021. WSP recognise that delivering social value would significantly benefit the Clun community and are keen to go beyond the technical expertise of designing drainage infrastructure to build a legacy for years to come, acting as a catalyst for long-term change. They would like to implement a ‘soft’ engineering approach given the local areas focus on conservation. WSP are keen to focus on reinstatement of existing historical ponds, using natural flood management and techniques to ‘slow the flow’, as opposed to building new infrastructure. This could include using existing systems such as ponds and wetlands, as well as reintroducing improved water concentrations and quality to support the presence of freshwater pearl mussels. Through reinstating and improving historical river elements to help flood management, the team also hope to improve the natural beauty of the area, provide a tourism hub, footpaths for recreation and the use of modern engineering techniques – all which could be shared with the local community.

What makes the project interesting? 

  • The project stands out due to the strong working relationship and partnership between WSP, Kier and Shropshire Council.
  • The project has included social value considerations from the initial bid stage.
  • Shropshire Council already have a range of locally run initiatives in place that the project team will be able to build upon.
  • The ongoing relationship between WSP and Shropshire Council will ensure that the social value initiatives are continued through the operational phase of the scheme with strong existing community ties and stakeholder engagement assisting with ongoing monitoring and reporting of social value outcomes.

Future considerations: 

  • Review key deliverables with Shropshire Council and assign these to social value champions who can implement and track progress.
  • Use the social value ideas tracker to map out relevant contacts for each initiative.
  • Develop a long-term plan with the Strategic Clun Liaison group to work alongside the community, the Council, landowners, and other stakeholders to report on progress and track opportunities.
  • Carry out another public consultation exercise during Spring 2022 to further communicate, evaluate and test their Social Value Delivery Plan.

Approaches Used

Agree social value purpose

  • Social value considerations were included from the initial project bid stage.

Identify priority stakeholder

  • Priority stakeholders were identified in collaboration with the Council during the early stages of the project

Put in place a social value measurement framework

  • WSP recommends the National TOMs framework to all their project teams (unless another framework is deemed more suitable). As a result, the TOMs framework has been selected for this project. The measurement approach has been approved by Shropshire Council.

Understand stakeholder needs

  • WSP held a ‘think tank’ workshop with multiple stakeholders including Shropshire Council and the Town Council. This session was used to brainstorm ideas for potential social value initiatives to meet the needs identified and develop the social value tracker.
  • WSP have engaged with local stakeholder groups, charities, and schools to understand local needs and to gather ideas for potential social value initiatives.

Ongoing measurement, monitoring and reporting

  • They have also identified local groups and individuals who are keen to help with the upkeep and monitoring of the final scheme.

Key Sustainability Objectives/ Outcomes

WSP are currently in the process of defining the projects priority social value outcomes. A social value tracker has been set up to record ideas and stakeholder engagement has begun with local groups.

The post Greening Swinton Square appeared first on UKGBC.

]]>

Project Overview

This case study is featured in UKGBC’s report, A Guide for Delivering Social Value on Built Environment Projects.

Strategic real estate advisor Avison Young, and local charity Groundwork Greater Manchester, with support from the IGNITION partnership, are undertaking an exciting pilot project throughout 2021/22 named ‘Greening Swinton Square’. Swinton Square is an established retail asset in Salford, Greater Manchester, which has been used by the community for over 45 years and currently comprises a range of retail, leisure and residential units. The Greening Swinton Square project aims to demonstrate how nature-based solutions (NBS) can be an integral part of the design of town centres. By delivering ‘more than just greening’ NBS can contribute to climate and nature outcomes, whilst also improving the vibrancy of town centres. As part of the wider IGNITON project, Greening Swinton Square is an example of how the city region can increase its resilience to the impacts of climate change by working with a range of landowners and communities. Engagement with Salford City Council has ensured that this project fits in with wider plans for the regeneration of Swinton town centre and it could form a model for other town centres across the city. To date, Greening Swinton Square has engaged various community stakeholders on the topic of NBS; what they are, how they can be used and the benefits they can bring. Following a series of engagement activities, Groundwork and Avison Young have started to work with residents, business owners and shopping centre visitors to co-design several NBS, such as living walls, green roofs, and rain gardens, which will be installed by the Groundwork team in spring 2022.

The Greening Swinton Square team have undertaken a creative engagement approach to establish the projects baseline, agree social value outcomes and develop the NBS design solutions, these include:

  • The creation of an on-site community hub in an empty retail unit. The hub has been home to interactive demonstrations of living walls, rain gardens and green roofs, allowing visitors to see, touch and feel these concepts and gain a much better understanding of NBS.
  • Interactive on-site events to understand community wants, needs and preferences.
  • Observations using MOHAWk tool5 (Method for Observing Physical Activity and Wellbeing) to record how people are using the space now.

Installation of the NBS is expected in March 2022, beyond this Avison Young and Groundwork Greater Manchester have committed to monitor the NBS, exploring the benefits and impact they have, as well as ensuring their ongoing maintenance.

What makes the project interesting?

  • Greening Swinton Square seeks to demonstrate the tangible benefits of investing in NBS beyond the immediate environmental and wellbeing benefits; exploring improved building performance and economic value to inform the investment case.
  • The partnership between Groundwork, as a local charity, Avison Young, as a commercial real estate manager, and wider IGNITION public sector partners, has allowed us to build a trusted relationship with stakeholders, gain in depth local knowledge and ensure a better understanding of stakeholder interests and what matters to each stakeholder group.

Future considerations: 

Once the full baseline data is in place, Avison Young will work with Groundwork Greater Manchester to develop a Social Value Measurement Framework and plan for ongoing monitoring and reporting.

Approaches Used

The project used an iterative approach, re-visiting some of the steps of the process multiple times, making refinements based on stakeholder engagement.

Key Sustainability Objectives/ Outcomes

Social value outcomes:

Health, Wellbeing and the Environment

  • Reduces pollution and street noise.
  • Better management of surface flooding.
  • Vital habitats and resources for a variety of local wildlife.
  • Potentially improved building performance through natural cooling.
  • Increased access to green space enhancing the health and wellbeing of the local community.

Strength of Community

  • Creates more opportunities to connect with, and learn about, nature.
  • A more attractive and vibrant local centre, which retains existing and attracts new users.

Jobs and Economic Growth

  • Potentially reduces centre costs through natural temperature control of buildings and management of surface water flows.
  • Provides an opportunity for an SME and registered charity, Groundwork Greater Manchester, to build expertise and utilise learning around NBS, to replicate in other places and settings, including community spaces.
  • Builds an investment case for green infrastructure, including NBS, within plans for local and district centres by demonstrating multiple benefits to a range of stakeholder.

Lessons Learnt

  • Early engagement with priority stakeholders, especially the Landlord (e.g. awareness of project decision windows/deadlines)
  • Regular engagement with beneficiaries to avoid misunderstandings (e.g. levels of disruption from construction work only days not weeks/months)
  • Early procurement decision-making and contingency options in order to mitigate supply chain disruption (e.g. COVID and the Suez Canal incident)
  • Ongoing collaboration throughout the lifecycle of the project (e.g. shopping centre management changed twice during the project)
  • Ongoing engagement with local stakeholders throughout the lifecycle of the project (e.g. stakeholders consulted at pre-design, delivery and post project to help with co-design and measure impact)

The post Langarth Garden Village appeared first on UKGBC.

]]>

Project Overview

This case study is featured in UKGBC’s report, A Guide for Delivering Social Value on Built Environment Projects.

Langarth Garden Village will provide a new, sustainable community for between 8,000 and 10,000 residents in Cornwall. Langarth will provide a mix of housing sizes, types, and tenures to meet local need. It will also include new schools, health, cultural, faith, leisure, and community facilities. Pedestrian and cycle links into Threemilestone and the surrounding communities will be created and enhanced, with new areas of forest, parks, parks, public sport areas and green amenity spaces. Innovative and flexible workspaces will also be provided. Over thirty organisations fed into the planning design work, fifteen of which are from Cornwall and contributed local knowledge and expertise. Arcadis leads the Portfolio Management Office (PMO) that oversees the management of all the programmes which feed into delivery of Langarth Garden Village including social infrastructure (led by Arcadis), integrated transport (led by Cornwall Council/Cormac) and technical infrastructure (led by Arcadis). The masterplan was developed by AHR with close support from Atlantic Arc Planning.

What makes the project interesting?

  • The project is aiming to create a community that is connected to the local area, whilst maintaining a proper village centre. Each centre hopes to attract local businesses that will be accessible to residents by walking or cycling.
  • There will be a community farm, allotments, edible streets, and several mobility hubs which will all contribute towards a sense of community.
  • The scheme will improve walking and cycling networks into Truro which will have a major benefit for Cornwall and encourage more people to choose to walk and cycle their commutes.
  • A new stewardship model will enable local ownership of the new community and allow the benefits of Langarth to be realised into the future.
  • There is a huge apprenticeship focus with apprentices working at the heart of the scheme providing career opportunities for those wanting to live and work in Cornwall.

Future considerations: 

Langarth Garden Village obtained planning approval in December 2021 with no objections.

Approaches Used

Agree social value purpose

  • Cornwall Council have a strong social value purpose and as a result, social value has been at the heart of the plans for the Langarth Village site from the beginning.

Identify priority stakeholder

  • A Langarth Stakeholder panel with representatives from a priority stakeholder groups. The stakeholder panel met once a month during the development of the masterplan.

Understand stakeholder needs and Agree social value outcomes

  • 10 design principles were agreed based on suggestions from the Langarth Stakeholder Panel.
  • These design principles were then incorporated into the masterplan.

Key Sustainability Objectives/ Outcomes

Ten design principles have been agreed by Cornwall Council and the Masterplanning project team at Arcadis:

  • Work with and enhance the quality of life for existing communities.
  • Make it easy and possible to get around on foot, bike, and public transport, both within Langarth Garden Village and the surrounding communities.
  • Help instil a strong sense of community.
  • Create a place that builds upon and celebrates this unique environment.
  • Create a hard-working landscape that not just looks beautiful but is productive and functional.
  • Promote healthy and active lifestyles and a sense of wellbeing.
  • Design for climate change resilience.
  • Offer a mix of homes meeting the varying needs of residents.
  • Create jobs and enhancing existing employment opportunities.

The post White Collar Factory appeared first on UKGBC.

]]>

Project Overview

This case study is featured in UKGBC’s report, A Guide for Delivering Social Value on Built Environment Projects.

White Collar Factory is an award-winning redevelopment of a major corner site on the Silicon Roundabout in the heart of the London’s Tech City. Construction was completed in 2017 and includes a new 16-storey 237,000 square foot office tower and low-rise campus buildings containing offices, retail, housing, and a new public square. Derwent London commissioned JLL to evaluate the socio-economic impact of White Collar Factory to understand the net impact (positive or negative) that the building has had on the local area and community.

What makes the project interesting? 

  • White Collar Factory is based in the London Borough of Islington, a borough with some areas of high deprivation (53rd most deprived borough in England). Local data demonstrated that there was a clear local need and an opportunity to have a positive social impact.
  • The project features several unique health and wellbeing initiatives including a running track.
  • Derwent London have committed to carrying out socio-economic impact assessments on all major projects once occupied. White Collar Factory was the first project where Derwent London investigated not only the development’s impact upon local stakeholders, but also measured occupier wellbeing. Also new to the assessment were insights from the alternative field of neuroscience.

Future considerations: 

Plans include projects that continue to build on the site’s integration to the local area and that bring businesses and local communities together, for example work experience and employment opportunities to showcase the sectors and companies that call this area home.

Approaches Used

JLL sought to understand the impact of White Collar Factory from the perspective of the stakeholders who experienced a significant change (positive or negative) as a result of the project. Identifying what changed for priority stakeholders helped JLL to move beyond traditional impact assessments that rely on output measures (e.g., number of workers) towards an assessment that focusses on outcome measures (e.g., improved quality of life scores or improved sense of place). The socioeconomic impact assessment focused on what value (if any) value the project has for the immediate neighbourhood and local stakeholders.

Identifying priority stakeholders

  • JLL began by brainstorming all potential stakeholders.
  • Priority stakeholders were then determined using a stakeholder prioritisation exercise to assess the influence each stakeholder has over the building (e.g., the extent to which they can influence the continued operation of the building) and the extent the building has an impact on them (e.g., livelihood or delivery of services). This exercise used a scale of 1 to 5 to provide a score.

Put in place a social value measurement framework

  • With priority stakeholders established, Envoy Partnership supported JLL to conduct an urban design and impact analysis to assess the buildings fit and sensitivity to the urban fabric of the local neighbourhood. This was complimented by qualitative interviews and surveys with residents, workers, and local businesses.

Key Sustainability Objectives/ Outcomes

Derwent London agreed four priority social value outcomes for the scheme:

  • Support local prosperity.
  • Create employment and training opportunities for local people.
  • Have a positive impact on the wellbeing of tenants and the local community.
  • Create net positive impact on the community.

Project Overview

This case study is featured in UKGBC’s report, A Guide for Delivering Social Value on Built Environment Projects.

Brent Cross Town is a £7bn new town centre development for London set around 50 acres of parks and playing fields. The scheme includes 3 million square foot of office space, 6,700 new homes, student accommodation, restaurants and sports and leisure facilities. Construction started in 2020 and the first permanent buildings will be completed in 2024. The Joint Venture partners (Argent Related and Barnet Council) are currently working with University of Manchester and Buro Happold to undertake innovative quantitative and qualitative research to develop a ‘Flourishing Index’ for Brent Cross Town. The ‘Flourishing Index’ will be used to inform social value target-setting and the development of a Social Value Delivery Plan.

What makes the project interesting?

  • The project is an example of a joint venture that has leveraged UK Research Council and match-funding to create transdisciplinary MA and PhD opportunities.
  • It is expected that all anonymised data collected will be open source. This will be achieved by working with Data for London.
  • The project involves the innovative use of both routinely collected and bespoke data, drawing on established and novel digital techniques. Both datasets were analysed based on input and interpretation from local people, stakeholders, professionals, and experts giving a deep understanding of the data.
  • Drawing on Medical Research Council and Nesta research standards, the project goes beyond Post Occupancy Evaluation, collecting ‘before and after’ data, providing a unique opportunity to understand additionality.

Future considerations:

  • Develop a social value delivery plan and an approach for ongoing monitoring and reporting.
  • The survey work involved working with adults and future work will look at developing a Flourishing Index for children and teenagers.
  • Consideration of global social impact via supply chains and local sustainable behaviours that may overlap with experiences of wellbeing.

Approaches Used

The ‘Flourishing Index’ is only one part of the social value delivery approach for Brent Cross Town. Over a three-year timeframe the following has been delivered:

Agree on social value purpose, identify priority stakeholder, and understand stakeholder needs

  • Argent Related with support from Buro Happold developed a Sustainability Strategy that set out a vision for Brent Cross Town to become a thriving and inclusive exemplar of urban regeneration. Desk-based research was used to understand local need and inform the Sustainability Strategy. This included analysis of previous stakeholder consultation, key local authority documents and various publicly accessible local datasets including ONS wellbeing scores and Joint Strategic Needs Assessments.
  • Online discussion groups were then held with a representative group of local community members (led jointly by University of Manchester and Buro Happold). These focused on understanding stakeholder definitions of health and wellbeing, and the priorities for change locally. The approach was based on the UK What Works Centre for Wellbeing and the National Institute for Health Research’s public engagement guidance. The findings of this work underpinned an initial Theory of Change, in turn, providing further foundations for the following steps.

Create a social value delivery plan and put in place a social value measurement framework

  • Rather than develop a social value delivery plan before putting a social value measurement framework in place Brent Cross Town needed a measurement framework to gather bespoke baseline data, ahead of the first major phases of Brent Cross Town delivery. The University of Manchester used a mixed-methods data collection approach, including intercept and online surveys (more than 1,500 participants), direct and automated behaviour observations (more than 10,000 observations), and air pollution monitoring. For each dataset, a matched UK or European comparison was sought.

Understand stakeholder needs and agree social value outcomes

  • To add further detail to the baseline data, complementary engagement activities with local stakeholders (community, businesses, local charities) were organised to plug any gaps in evidence. This led to a more comprehensive list of outcomes and indicators within the ‘Flourishing Index’.

Create a social value delivery plan

  • As part of preparation for a forthcoming Social Value strategy, examples of national and international best practice were compiled.

Ongoing measurement, monitoring and reporting

  • To continue the ‘golden thread’ of stakeholder engagement, the baseline findings and best practice examples were co-interpreted, to set salient and ambitious targets – providing ‘north stars’ to guide the Social Value Strategy and planned ongoing monitoring.

Key Sustainability Objectives/ Outcomes

Social Value outcomes

The ‘Flourishing Index’ includes:

  • Subjective Wellbeing (SWB)
    • Personal SWB outcomes (hedonic and eudaimonic) e.g. “life going well for me”.
    • Social SWB outcomes e.g. life going well for “us”.
    • Specific SWB outcomes including satisfaction with key aspects of life such as income, jobs, and housing.
  • Key wellbeing activities e.g. Connect, Be Active, and Take Notice.

FEASIBILITY STUDY: Riverbank School Retrofit https://ukgbc.org/resources/feasibility-study-riverbank-school-retrofit/ Thu, 15 Sep 2022 12:06:21 +0000 https://ukgbc.org/resources/feasibility-study-riverbank-school-retrofit/ A feasibility study to assess the cost, carbon count and environmental performance of varying levels of renovation taking place on a school building.

Project Overview

Detailed energy modelling and a Life Cycle Assessment (LCA) were undertaken to determine the whole life carbon emissions of each option. The LCA was one of the first of its kind due to its inclusion of the embodied carbon of both the existing building structure and of the demolition. This allowed for an accurate comparison between the retrofit options and an equivalent new build school. 

Key Sustainability Objectives/ Outcomes

In Scotland, one can receive funding through the Outcomes Based Funding (OBF) model when building a new school / renovating an existing one. Current funding metrics consider energy performance as a key determinant. This often results in the development of a new school being the default option to achieve the best possible energy performance. However, there is currently no consideration for embodied carbon as part of these metrics.  

This creates a trade-off between the better energy performance that may accompany building a new school versus the increased embodied carbon that such an action would entail. The refurbishment of an existing building – or even doing nothing at all – could result in lower emissions overall. Therefore, it is vital to consider embodied carbon as a key factor in identifying the best value approach. This was the aim of the Riverbank study, accompanying its study of cost, condition, suitability, risk and programme. The four options that were assessed included:

  • A base level refurbishment.
  • An enhanced retrofit.
  • An optimum retrofit.
  • A new build school. 

Although the new build resulted in the lowest energy consumption, energy modelling determined that the optimum retrofit was still able to achieve 76.6kWh/sqm/year, placing it into the same energy performance band as the new build option (Band A: 67-83kWh/sqm/year). They also both received condition and suitability ratings of A (Aberdeen City Council).

There was a significant difference in embodied carbon across the four options, with the new build having the highest value (46% greater than the optimum retrofit, 61% greater than the enhanced retrofit, and 136% greater than the base level refurbishment). In contrast, there was a minimal difference in cost between the options, with the new build costing only 0.5% more than the optimum retrofit. This suggests that the key benefits to retrofit lie within embodied carbon statistics, rather than cost savings. The results of the study were presented to Aberdeen City Council and LEIP (Learning Estate Investment Programme) who are now reassessing their funding metrics to potentially include embodied carbon as a key determinant going forward.

Notable Approaches And Solutions

  • Enhanced energy modelling.
  • Early stage LCA including embodied carbon calculation of the existing structure and demolition to allow for an accurate comparison between the retrofit options and an equivalent new build school.
  • Detailed cost assessment.
  • Detailed programme assessment.

Lessons Learnt

The embodied carbon calculation for the LCA in an existing building structure is not yet a widespread practice. This resulted in resistance from environmental consultants and therefore required extensive work on the part of project architects and quantity surveyors to break down the existing structure into its fabric elements. A detailed breakdown of the embodied carbon was thus determined, enabling an accurate comparison between the different retrofit options and the new build school.
