ASSESSMENT OF INDOOR ENVIRONMENTAL TEMPERATURE AND HEAT BALANCE COMFORT MODEL

Global warming has been recognised as having significant effect on the ecosystem, weather, and resident's health.In the past century the average global temperature has risen.However, the temperature has increased more obviously during the last decades.The geographical temperature anomaly indicates the global temperature changes and the rise of global temperature which is an effect by the increase of greenhouse gas.Carbon dioxide, which is the main greenhouse gas, arises in large quantities from human activities.Since the industrial revolution, the carbon dioxide emission has increased rapidly.A large amount of carbon dioxide derives from the combustion of fossil fuels such as coal, oil and gas.Heat balance comfort model deals with a subjective feeling whereby occupants feel satisfied with the indoor environment.And it is related to the energy balance between metabolic rate and heat loss from the human body.The heat loss is demonstrated by radiation, convection, and evaporation.The result showed that the highest indoor air temperature will rise to 34.5C when single side glazing was plotted in the model, and reduce to 30.25C when double side glazing was plotted.Approximately 4C difference can be found, compared with single side glazing and double side glazing.It clearly presents the importance of a heat balance comfort model for indoor temperature.Therefore, a good design of window can save 40%-50% of energy consumption in non-domestic buildings.Heat balance comfort model influences good energy performance can reduce energy consumption and provide comfort for the indoor environment.Recommendations were made to adopt appropriate design strategies to each climate zone by considering indoor environmental temperature and heat balance comfort model which greatly reduces energy use and greenhouse gas emissions.
