ABSTRACT
Energy services in buildings – the provision of thermal comfort, refrigeration, illumination, communication and entertainment, sanitation and hygiene, and nutrition, as well as other amenities – are responsible for a significant share of energy use worldwide. In addition to the energy consumed directly in buildings, primary energy is lost in the conversion to electricity and heat and petroleum products, and the transport and transmission of energy carriers cost energy. in addition, the construction, maintenance and demolition of buildings requires energy, as do the manufacturing of furniture, appliances, and the provision of infrastructure services such as water and sanitation. this study investigated demand for sustainable in office buildings in Lagos. The method for data collection was through the design of self-administered questionnaires. the data collected was analyzed using chi-square, where the critical value was p value
CHAPTER ONE
INTRODUCTION
1.1BACKGROUND TO THE STUDY
Over the past few years, the concept of sustainability has become increasingly popular in discussions with in the commercial property sector. According to the Investment Property Forum, (2009), this has been largely fuelled by a growing understanding that commercial buildings are major contributors to increased carbon emissions due to increased energy usage which most experts now acknowledge is a major cause of climate change, and that improving the energy efficiency of such buildings can help reduce emissions and the consequential strain on the environment.
The change in energy use patterns and intensity in the built environment and the growing carbon footprint and other environmental concern has been attributed to the increasing demand for real estate and the changes in design and construction strategies, materials and product development which initiated the supply of more complex buildings with massive growth in energy, carbon and environmental footprint (U.S Department of Energy , 2010) and this, today has been the major reason for the increased drive for optimized use of energy resources and provision of green and sustainable buildings.
