Energy and utilities consumption – an appraisal in sustainable buildings
Abstract
The rate of use of energy and utilities in cities is of great concern and necessitates appraisal especially when fossil fuel has been largely blamed for the global warming and climate change threats. This study investigates the involvement of professionals in the built environment during the design, operation and maintenance activities associated with energy and utilities consumption in buildings with a view to improving their management performance. Survey was directed to the building services engineers, estates and facilities managers within healthcare and educational sectors in the United Kingdom in pursuit of gathering energy and utilities consumption data. Issues that influence and support sustainable energy and utilities management practices were also sought during this study. A functional unit size of 100 m2 in each of the investigated buildings was considered as basis for analysis and comparison thus, the achievable results using sustainability indices option as an indicator for both healthcare and educational sectors are 0.74 and 0.64. At the decommissioning stage of this buildings, the critical levels of service delivery are 0.27 and 0.24 respectively from both healthcare and educational sectors. These results are considerably satisfactory of the energy and utilities usage performance.
