Thus, the energy performance of housings has improved radically over the past decades. Yet other types of buildings, in particular commercial centers, haven’t received the same level of interest. As a result, there is a need for effective and practical measures to decrease their energy consumption, both for heating and electricity. The objective of the paper is to demonstrate that it is possible, through coherent strategies, to integrate energy issues and bioclimatic principles into the design process of commercial centers. It analyzes the exemplary case study of Marin Commercial Center (Switzerland). The interdisciplinary approach, based on integrated design strategies, aimed at increasing the energy efficiency while keeping the cost comparable to the market cost. The main design principles include natural ventilation, nighttime cooling with energy recovery and natural lighting, as well as optimization of mechanical systems. The results of the simulations show that Marin Center attains the best energy performance observed so far among Swiss commercial centers. It also meets the Swiss Minergie standard. The paper thus questions traditional design processes and outlines the need for interdisciplinary evaluation and monitoring approaches tailored for commercial centers. Even though most crucial decisions are taken during the early stages, all phases of the process require systematic optimization strategies, especially operating stages. Recommendations include legal measures, in particular in the fields of ventilation and air-conditioning, education, professional development and technology transfer, and financial incentives for the replacement of energy intensive installations.展开更多

It is expected that there will be more heat waves, floods, bush fires, coastal erosion and drought. Unfortunately, Australia is vulnerable to climate change due its hot and dry climate and as the driest state; changes are already being felt in South Australia. There is an urgent need to start adapting to climate change to cope with present and predicted climate change in the future by changing or adjusting building regulations, land use plans, and land subdivision regulations. This paper aims to provide design guidelines for adaptation to climate change at the neighborhood level. A case study method was adopted to achieve the aim of this paper. The study was conducted in two stages. The first stage presents the current design of neighborhood and its adopted design parameters for climate change. The second part provides the design guidelines for adaptation to climate change at the neighborhood level. The case study has a well oriented grid iron layout that serves as the basis of orienting and sitting future buildings that can adapt to climate change. However, the orientation of roads is good, it will be necessary to reconfigure elements of landscaping and built environment in order to address climate change in built environment by modifying design elements.展开更多
