Growth in population and households, and lifestyle changes are factors placing water resources under increasing stress in some parts of the UK. The Code for Sustainable Homes (CSH), a government regulation defining performance standards for new dwellings, is one measure that may act to counter rising domestic water demand. One goal of the CSH is to reduce potable water use per capita in each home through implementation of water conservation measures. The main aims of the research are to assess what impact the CSH might have on future regional household water demand, and to understand the level of CSH uptake, at various performance levels, needed to achieve Government aspirations of 130 I/c/d. The thesis investigates the effects of implementation of the CSH on regional domestic demand in the area served by Yorkshire Water Services (YWS). The uncertainty surrounding CSH implementation means it was necessary to study . a range of possible futures comprising aspects of the technology implied by the CSH, demography and construction trends. A spread sheet model was developed to assess domestic water demand under a range of CSH uptake scenarios, as well as a range of demographic, technical, economical and behavioural aspects of water consumption and conservation. One finding was that not even building the total amount of planned dwellings to the highest performance level of the CSH will suffice to achieve the Government target; hence backcasting scenarios were also developed in order to asses to what extent water conservation strategies in the extant stock together with the CSH in the new stock can help achieve the target for 2030. The work explores feasible scenarios considering physical constraints, costs and people's acceptability. |
