The Cost

A well-designed energy efficient building maintains the best environment for human habitation while minimising the cost of energy. The energy efficient buildings are to improve the comfort levels of the occupants and reduce energy use (electricity, natural gas, etc) for heating, cooling and lighting (Development and Land Use Policy Manual for Australia, 2000 and United Nations, 1991). This paper is an inquiry to investigate the users' perceptions towards lights and space of energy-efficient buildings. The research is based on qualitative and quantitative data collection. The findings revealed that users have mixed feeling towards light and space especially with the use of new working practices i.e. hot desking, hotelling etc. Keywords light, space, user perception, energy efßcient building. eISSN 2514-751X © 2018.

There is a growing demand for sustainable retirement villages in Australia due to an increasing number of ageing population and public acceptance of sustainable development. This research aims to gain a better understanding of retirees’ understanding about sustainable retirement living and their attitudes towards sustainable developments via a questionnaire survey approach. The results showed that the current residents of retirement villages are generally very conscious of unsustainable resource consumption and would like their residences and community to be more environmentally friendly and energy efficient. The cost of energy supply is a concern to majority of respondents. However there is a certain level of concerns from residents too on the extra cost of going green in their residence. Education is required to residents about recycling household waste and how to use available facilities. A better understanding of retirees’ awareness and attitudes towards sustainability issues helps to improve the sustainable developments of retirement villages in the future.

Energy Efficient Buildings

Rising demand and limited production of electricity are instrumental in spreading the awareness of cautious energy use, leading to the global demand for energy-efficient buildings. This compels the construction industry to smartly design and effectively construct these buildings to ensure energy performance as per design expectations. However, the research tells a different tale: energy-efficient buildings have performance issues. Among several reasons behind the energy performance gap, occupant behavior is critical. The occupant behavior is dynamic and changes over time under formal and informal influences, but the traditional energy simulation programs assume it as static throughout the occupancy. Effective behavioral interventions can lead to optimized energy use. To find out the energy-saving potential based on simulated modified behavior, this study gathers primary building and occupant data from three energy-efficient office buildings in major cities of Pakistan and categorizes the occupants into high, medium, and low energy consumers. Additionally, agent-based modeling simulates the change in occupant behavior under the direct and indirect interventions over a three-year period. Finally, energy savings are quantified to highlight a 25.4% potential over the simulation period. This is a unique attempt at quantifying the potential impact on energy usage due to behavior modification which will help facility managers to plan and execute necessary interventions and software experts to develop effective tools to model the dynamic usage behavior. This will also help policymakers in devising subtle but effective behavior training strategies to reduce energy usage. Such behavioral retrofitting comes at a much lower cost than the physical or technological retrofit options to achieve the same purpose and this study establishes the foundation for it.

House frontage is an essential aspect of terraced house design to ensure the occupant's comfort and healthy living. Four samples selected to evaluate the influence of the window to wall ratio (WWR) towards the internal thermal comfort of the house. The indoor thermal parameters were recorded using HOBOware Data Logger and evaluated using CBE Thermal Comfort Calculator. The study shows that the living room with a bigger WWR had the lowest thermal comfort levels. Besides the WWR, window placements and the shading devices also help in reducing the sun exposure of the frontage wall and increase the indoor thermal comfort.

Daylighting has attracted increasing attention from researchers as an energy-efficient and sustainable building design technique. This research investigates the daylighting of atrium and courtyard building by comparing the performance of various Window to Wall Ratios (WWR) appropriate to Malaysia's tropical climate. The most acceptable option for daylight performance was to specify a moderate WWR value of 30% with shading devices. The results of The Radiance Daylighting Simulations confirmed the daylight performance by a comparison of calculated data and modelling. The findings show the combinations of daylighting parameters that work for courtyard and atrium buildings for the occupants' wellbeing.

Energy Efficient Buildings

Cooling, Heating and Power (CHP) systems are a form of distributed generation that uses internal combustion prime-power engines to generate electricity while recovering heat for other uses. CHP is a promising technology for increasing energy efficiency through the use of distributed electric and thermal energy recovery-delivery systems at or near end-user sites. Although this technology seems to be economically feasible, the evaluation and comparison of CHP systems cannot be restricted to economical considerations only. Standard economic analysis, such as life cycle economic analysis, does not take in consideration all the benefits that can be obtained from this technology. For this reason, several aspects to perform a non-conventional evaluation of CHP systems have to be considered. Among the aspects to be included in a non-conventional evaluation are: power reliability, power quality, environmental quality, energy-efficient buildings, fuel source flexibility, brand and marketing benefits, protection from electric rate hikes, and benefits from promoting energy management practices. Some benefits of these non-economical evaluations can be transferred into an economic evaluation but others give intangible potential to the technology. This paper focus on a non-conventional evaluation based on energy-efficient buildings, which is associated to energy conservation and improvement of the building energy performance rating for government energy programs like Energy Star and Leadership in Energy and Environmental Design (LEED). Results show that the use of CHP systems could improve the Energy Star Rating in more than 50 points. The Energy Star Rating is significant on the LEED Rating as a building can score up to 10 points of the 23 available in the Energy & Atmosphere category on energy efficiency alone. As much as 8 points can be obtained in this category due to the Energy Star rating increment from the use of CHP systems. Clearly the use of CHP systems will help building owners to reach the benefits from these energy programs while improving the overall energy use and energy cost.
