Demolition or Refurbishment of Social Housing? A review of the evidence
This report provides a review of technical models, evidence and case studies for decision making relating to the retention or demolition of social housing stock. Technical assessments of building suitability for refurbishment or demolition are often based on models of building performance. These include energy performance of the building compared to standards for new buildings, and assessment of environmental and energy impacts of the building over its lifetime from construction to demolition. Decisions can also be based on a series of performance and cost indicators. All modelling and indicator based approaches require assumptions about the building and the economic and policy context in which regeneration will take place, which need to be examined and justified in each case. Evaluation of the economic case for refurbishment is sensitive to the institutional factors such as the UK retrofit supply chain and market; tenure types and management capacity; access to finance and/or willingness to invest. Typical cost indicators are capital expenditure, operational and maintenance expenditure and capital investment appraisal. Estimating the costs and impacts of refurbishment or demolition is complex, uncertain and subjective – especially where nonmonetary costs and benefits have to be assigned a value. Finance mechanisms for refurbishment are less well established than for construction. The energy performance of a building is an increasingly important consideration in decisions to demolish or refurbish, and it has a big impact on the health of residents and the cost of their energy bills. Energy is used by residents as they live in a building throughout its lifetime. Energy is also used to manufacture building materials and construct the building in the first place and then in demolition, reusing, recycling and moving materials to dispose of them. Reducing carbon emissions associated with the built environment means reducing the emissions associated with the whole lifecycle of buildings. However, refurbishment and ...
