Energy Consumption Patterns

Towards sustainable campus of higher education institutions (HEIs), energy consumption behaviour is one of the several matters that require attention by the facilities manager. Information on energy consumption behaviour helps on developing a good strategy for energy management. The purpose of this study is to assess energy consumption behaviour among Malaysian HEIs student. This study has an objective to determine energy consumption patterns and analyse the factors that influence the pattern. The 'energy culture' framework consolidated with 'centrographic' approach and econometric analysis used to strengthen the findings. A self-administrated survey carried out involving 158 respondents in Universiti Teknologi Malaysia, Johor. There are three types of energy use among students in HEIs namely, 'high', 'low', and 'conserve'. The 'device', 'activities' and 'building regulation' are the influence factors on the pattern of energy use.

Electrical and energy production have a noticeable water footprint, and buildings′ share of global energy consumption is about 40%. This study presents a comprehensive experimental analysis of different thermal impacts and water consumption of green roofs in a Mediterranean climate. The study aims to investigate the use of water directly for green roofs and reduce the water footprint of energy in summer and winter due to its thermal impacts. The measurements were carried out for an extensive green roof with an area of 55 m2 and a thickness of 22 cm, and direct water consumption by a green roof and direct and indirect water consumption by cooling and heating systems were analyzed. According to the analysis, in summer, the maximum roof temperature on a conventional roof was 72 °C, while under the green roof it was 30.3 °C. In winter, the minimum roof temperature on a conventional roof was −8.6 °C, while under the green roof it was 7.4 °C. These results show that green roofs affect energy consumption in summer and winter, and the corresponding thermal requirements for the building have a water footprint regarding energy production. In summer, the thermal reduction in the water footprint by a green roof was 48 m3 if an evaporative air conditioner is used and 8.9 m3 for a compression air conditioner, whereas the water consumed in the green roof was 8.2 m3. Therefore, using water directly in the green roof would reduce the energy consumption in buildings, and thus less water has to be used in power plants to provide the same thermal impact. In winter, green roofs′ water consumption was higher than the thermal water footprint; however, there is no need to irrigate the green roof as the water consumed comes from precipitation. This experimental analysis determines that in the Mediterranean climate, green roofs allow the achievement of the same thermal conditions for buildings in both summer and winter, with a reduction in water consumption.

This chapter concisely discusses two case studies experiences on domestic refrigeration. One of the cases involves the theoretical and experimental analysis of the thermal profile in the compartments of a refrigerator, all this under the modeling and simulation through CFD, thus obtaining interesting results in terms of energy consumption. The second case is focus on the thermal and energy evaluation of new material proposed as thermal insulator, which was developed in a conventional way in the laboratory and presents convenient thermal features. Therefore, the guidelines for this chapter are aimed at finding mechanism that streamline the domestic refrigeration systems, without modifying its cooling performance.

Purpose In working towards a sustainable campus of public universities, energy consumption behaviour assessment is one of the several issues that requires attention by the facilities manager. Information on energy consumption behaviour is needed to determine potential energy savings. The purpose of this study is to assess energy consumption behaviour for student accommodations in Malaysian public universities. Design/methodology/approach This study focuses on developing energy consumption behaviour models (ECBMs) and assesses the potential energy savings. The “energy culture” framework consolidated with multiple regression analysis is used to strengthen the development of ECBMs. A self-administrated survey involving 1,009 respondents in selected public universities was carried out. Findings The result shows that five factors from the energy culture framework contribute to energy consumption behaviour, namely, building regulation, environmental concern, education, social marketing and direct factors (device and activities). These factors are included in the model for predicting energy consumption levels. The results show that there is a 78 per cent difference in energy consumption between the observed and predicted data. Practical implications This study indicates a high potential energy saving among students of Malaysian public universities. Originality/value The model was tested against the overall students among Malaysian public universities. In future, the model can be tested within hostel accommodations. The present assessment revealed the potential energy saving among the hostel buildings and sets the target regarding which building has a potential to reduce energy. It also helps the facilities managers to come up with strategies for programmes and energy policy in public universities.
