Abstract:
Non-domestic buildings account for 12% of UK greenhouse emissions (CIBSE, 2017). There is acceptance that the energy performance of buildings must improve. Presently building energy data is only available in terms of total annual fossil or electrical energy totals. These are blunt instruments for energy managers. There is a need for a method of managing the energy of individual building services components through all project phases. This study aims to examine present methods for building energy use estimation and to develop a strategy whereby building energy use can be managed from feasibility through to building operation. The research methods centred around six case study buildings. Five of the case study buildings selected are existing, were built at different times, under different statutory energy regimes and therefore different design philosophies. The sixth case study building is under construction. Investigating the energy performance of buildings involved applying the most up to date system of energy estimating techniques and comparing results with benchmarks and actual energy use. Surveys and record data for one of the buildings was investigated in order appreciate the implications of design margins and the effectiveness of control arrangements for circulating pumps. The results of these case studies and investigations provided the basis for the development of an energy management strategy. Although building energy models have streamlined the design process, outputs have been found to be optimistic. This study has found that it has not been possible to reconcile energy use predictions, benchmarks or utility bills with actual energy use for individual building services components. Additionally, monitored performance data is not utilised to quantify the effects of plant over-sizing. This thesis proposes an energy management strategy which enables the energy use of individual components of a building services project to be managed through all project phases. It is proposed that this methodology should also be developed into a facilities management programme for buildings.
