Energy efficiency and conservation in an office building: a case study

Purpose – The purpose of this paper is to present a case of an office building in England and show how the technology in energy efficiency in building will contribute to energy conservation. Design/methodology/approach – The paper presents a case of an office building. The building is then modelled and analysed using IES Virtual Environment VE to estimate the Target Emissions Rate (TER) and the Building Emissions Rate (BER) to see how the building could satisfy Part L of the Building Regulations. Findings – The building in case use various sustainable solutions such as limiting the heat loss and gain through the fabric, ventilation system with a good high heat recovery system, increasing the availability of daylight and good lighting control system. The office building in the case study is in full compliance with Part L of the Building Regulations. The sustainable technology in the building will assist the compliance with Part L of the Building Regulations. Research limitations/implications – This is a single case study building; more case studies for buildings of this nature are required. Practical implications – The paper demonstrates various feasible solutions of sustainable technology in buildings that might help comply with the regulation. Originality/value – The case study building is a real case taken directly from one of the author's projects when he was working as a building services engineer. This case study building and its sustainable features have not been presented before in an academic journal.
