Energy performance of non-residential buildings : a local case study

Abstract

Current trends imply an increase in energy consumption which not only result in increased oil and electricity prices and scarcity of non-renewable sources of energy, but it also contributes significantly to the growth of greenhouse gas emissions and climate change. It was thus imperative that a series of regulatory acts in the field of energy efficiency and environmental protection be established. Locally a methodology for the assessment of residential buildings has been complied however research in the field of non-residential buildings is still in its Initial stages. This fact, as described in Chapter 1 has contributed to focusing this study on the latter. The principle aim of this study is therefore to analyse the present internal environment and energy flows within a non-residential building, to explore the significance of the influencing parameters and hence to generate scope for further study in this field. A school was selected as the case study building. A general background of how various countries are tackling this issue is explored in Chapter 2. European methodologies were adopted in order to obtain a clear understanding of the above. Present comfort levels within the building were assessed and compared to standard comfort levels required that were discussed In Chapter 3. Questionnaires to the occupants and site surveys were also conducted to extract required data. Chapter 4 explains the principles and procedures followed in order to reach the scope of the study. Results in Chapter 5 indicate that not all comfort levels are met and that ventilation within the building is a main concern. Chapter 6 discusses a number of proposals which could contribute to the improvement of the energy performance of this building. It also highlights areas of interest for future studies.
