Analysing Meteorological Variables, Energy Consumption and Occupant Behaviour in an Office Building in Hot-Humid Climate Zone

Abstract: In the last decade, new designs target green buildings, which emphasised the prominence of energy conservation and efficiency. Designing a green building in a sustainable way does not promise it will be energy efficient, as consumption is heavily relied on occupant behaviour. Besides, the variation of energy consumption is also associated with meteorological variables, which are highly significant in the building sector. Thus, it is vital to understand the influence of these factors on energy consumption in which a better understanding of it can contribute to a more effective strategy in meeting energy conservation goal. This paper presents analyses of meteorological variables, occupant behaviour and energy consumption in terms of electricity consumption based on field data collection conducted in August 2012- August 2013 in an office building located in Northern Peninsular of Malaysia. Meteorological data were recorded and monitored using a weather station system, and monthly energy consumption data were recorded based on meter readings. Analysis of occupant behaviour was carried out through a questionnaire survey (r=0.825) to 40 occupants of the building. The questionnaire was divided into four sections i) demographic data, ii) knowledge and awareness about energy, iii) perception and view of energy consumption and efficiency and, iv) energy practices. From the study it was found that the meteorological variables in terms of outdoor mean temperature, outdoor relative humidity and wind speed ranged from 27.4 to 29.3C, 77.4 to 81.3 % and 1.6 to 2.3 m/s. Most of the occupants in this study had high knowledge and awareness about energy, and they gave a positive feedback on view of energy consumption and energy efficiency. In contrast, these behaviours did not translate to good energy practices among the occupants as low energy efficiency practices were observed in this study. In conclusion, meteorological variables and occupant behaviour had an influence on energy consumption in the case study building. However, a more detailed investigation should be carried out concerning this area in the future
