Sustainable Return on Investment
Finding the Lingua Franca for Sustainable Development
The value of the environment often limited to negative elements such as the cost of waste or required investment in energy conservation.
The value of social issues are rarely calculated also cost associated with Social Value can be noted in terms of more costly recruitment of local people (for example).
This leaves return on investment on labour, materials and sale/rent as the dominant way to gauge the value of built environment projects today – but this is only part of the value
Invisible Value
Environment: Enhancing land value, preventing flooding, producing goods and services, influencing aesthetics and well-being
Social: Improving health, reducing crime, facilitating educational attainment, offering the context for job creation, improving social mixing and social cohesion
Each impact has a potential monetary value, but not all can or should be represented in the price point
Social and Environmental Valuation Tools
Environment: • Life Cycle Assessment data-base tools such Trucost and other bespoke products • Ecosystem Services Analysis • Construction BIM software design tools
Social: • Social Return on Investment (SROI) – This can cover the range of social impacts and benefits providing indicators and proxies can be sources from the statistical record
Combining Social and Environment
The combination of social and environmental methodologies to value regeneration programmes can be called Sustainable Return on Investment
Current Projects
• RICS Research Trust – Developing an Approach to Sustainable return on investment in the UK, Brazil and the USA
• City West Housing – Evaluation of 9 social and environmental improvement projects
• Broughton Trust – Evaluation o the Irwell Valley Sustainable Communities Programme
• WSP – Evaluation of a sustainable improvement programme as part of a 2-year demolition programme, London
• Plus Dane Housing Group – Assessment of a Youth Engagement programme in an underinvested part of Liverpool
Key Elements of the PIEC Programme
• Urban infrastructure including adequately sized sewers
• Landscaping • Community activity space • Income generation programmes • Community development.

Stages of the Ecosystems Services element of the SuROI Study
• Step 1 – Identify and define the area of the study
• Step 2 - Identify the ecosystem services and disservices
• Step 3 – Assess the value of the existing ecosystem services as a benchmark
• Step 4 – Assess the value of the ecosystem services after the intervention
• Step 5 - Compare the outcomes

Social Outcomes Under investigation
Residents have improved job prospects Residents have more education/qualification Residents feel better through access to higher quality parks and
gardens Residents gain new or better employment positions Resident's experience improvements to health through more provision
of health services Better community democracy/decisions/demands results in lower levels
of crime Residents are healthier due to better quality of housing Residents feel safer because of safety measures they build into their
new houses Are healthier due to improved flooding and sewage drainage

Other Valuation Tools
• Life Cycle Assessment (LCA) can identify embedded carbon, emissions, damage from resource sourcing and labour conditions
• Building Information Modelling (BIM) can value can value occupation costs from various energy and lighting management systems perspectives
• Behavioural studies can value the cost of various ways buildings can be operated
