Environmental sustainability of future social housing
Excessive resource consumption and other unsustainable practices have in recent decades contributed to the current global climate emergency. Unsustainable practices are especially prevalent in housing design, construction and operation equally in new and retrofit projects. In the UK, the social housing sector forms up to 18 per cent of the entire housing stock (4.2 million units in 2021), consumes up to 5.3 per cent of the country’s energy and causes 3.6 per cent of its carbon dioxide emissions. To achieve net-zero carbon emissions by 2050 and build a decarbonised housing sector with a minimum C rating on Energy Performance Certificates (EPC) across all homes by 2030, the UK government has developed several initiatives (decarbonisation fund), policies and procedures (among many, the Code of Sustainable Homes, Energy white paper, and the National Design Guide are most notable). However, in 2019, 48 per cent of UK housing providers thought that government sustainability policies and target objectives were unclear. These unclear expectations, complex and fragmented sustainability codes and standards, widespread misperception of environmental sustainability tools and concepts, and a vague energy-efficiency transition pathway have also hindered UK sustainability progress.
This project challenges existing methodological practices, which the project argues are ineffective due to the practice policy’s complexity and fragmentation. The project assesses methodological and practice policy effectiveness in terms of their roles and effect on social housing sustainability in the UK (both retrofit and new construct). The project aims to answer the following questions: (1) what is the current perception and structure of housing and sustainability practices?; (2) how do we define and measure housing sustainability?; (3) what tools can be used to achieve an efficient decarbonised housing sector?; and (4) what should the standards for future homes look like to promote simple and effective practices?
The first of this project’s three aims is to identify sustainability and housing policies, codes and standards and determine their development timelines and impacts on the investigated topics. Its second objective is to develop a comprehensive understanding of sustainable social housing practices and the emerging concept of decarbonisation by investigating housing and sustainability policies, definitions, principles and theories. The third objective is to examine and map the landscape of current sustainability tools, codes and guidelines in the UK.
To accomplish its aims, this project adopts a mixed-methods approach. The project conducts a qualitative investigation to form a theoretical base and establish definitions, principles and policy timelines. The project’s qualitative instruments include desk study, focus group discussions with experts in the field, and semi-structured interviews with housing practitioners. The project’s quantitative approach aims to map the current-practices landscape and measure how effectively current practices meet environmental sustainability targets. The project’s quantitative tools include questionnaires (end-users and practitioners) during the planned secondments, and analysis of decarbonisation progress using statistics.
This project’s expected outcome is a policy and practice framework that addresses the environmental sustainability of social housing and provides practical design and planning guidelines for achieving a ‘decarbonised’ housing sector in the UK. This framework will be significant due to its potential to trigger a national wide change, support practical developments in housing sustainability and to prompt future studies on achieving sustainable social housing through simplified and effective codes and standards.

Environmental Sustainability of Future Social Housing
Environmental sustainability and resource efficiency are vital concepts to improve and protect our planet. Both concepts are also relevant to housing design, construction and use. With the support of local housing communities, the UK social housing sector is set to increase rapidly. In the UK, housing accounts for 30 per cent of the total energy use, 27 per cent of UK carbon dioxide emissions, while at the same time, social housing forms up to 18 per cent of total housing stock. Therefore, we must reconsider new ways of building sustainable and affordable homes that improve the quality of the built environment and create better places for people to live.
This project addresses two challenges. On the one hand, it establishes a clearer conceptual understanding of low-cost sustainable housing by investigating the definitions, principles, and theories associated with its construction. On the other hand, it examines sustainability practices currently in use by looking at the sustainability tools, guidelines, codes, and standards for achieving low-carbon homes. Consequently, this project will answer the following questions in the UK context: how do we define and measure housing sustainability? What tools can be used to achieve low-carbon housing? How do we achieve a decarbonized housing sector?
A mixed methods research design will be used. Qualitative instruments, including a literature review and case studies analysis, will identify current sustainability definitions, meanings and methods of practice. Meanwhile, quantitative instruments focused on statistical reports and sustainability codes aim to review the existing assessment methods and develop a comprehensive understanding of sustainability assessment principles.
The planned outcome of this project is to develop a comprehensive framework that promotes the sustainability of social housing. This framework will be developed in collaboration with relevant stakeholders, including local social housing communities. It will include a theoretical database that defines the theories and principles of “low-carbon design and planning of housing”; at the same, it will form a clear, practical guideline for achieving “decarbonized housing” by improving current standards and codes of practice, therefore bridging the gap between theories of housing sustainability and actual practices of housing construction in the UK.
