“…For instance, green roofs are found to contribute to energy savings in the house by providing insulation, thus reducing the heating demands of buildings [79,80]; while climate-adaptive building shells are expected to offer better energy performance as well as daylight illumination [81]. The only measure that considered the user experience, together with environmental parameters, was conducted by Chen and Chiu [21] in the context of smart skins; smart windows, solar chimneys, solar-source heat pump systems, and model-predictive heating controllers are all dependent on external factors (i.e., environmental parameters) [22,[82][83][84].…”

Climate change requires our built environment to be adaptable in order to serve the community well. Among the components of the built environment, housing and its occupants are especially vulnerable. Over the years, there have been variations in the designs and building techniques used in the construction of houses able to adapt to these changes. In this study, a systematic review with the preferred reporting items for systematic review and meta-analyses (PRISMA) protocol was conducted to identify, classify, and investigate existing climate-adaptive measures for housing on the basis of 65 articles selected. In total, 21 climate-adaptive measures were identified and classified into three categories, namely, passive design, building technology, and building performance assessment tools. From the identified climate-adaptive measures, 16 distinct benefits were identified, the majority of which are related to improved thermal comfort and energy efficiency. This review lays the foundation for further research examining the roles of existing, new, and emerging technologies in enhancing building performance and the adaptive ability of houses in response to climate change.

 Abstract: World over building sector is largest consumer of electrical energy. Energy requirement for air cooling and refrigeration is found to be 40 % of total consumption of electrical energy used in building sector. Passive cooling technologies used in building have good potential of indoor air cooling many building built on these principles are showing reduction in energy requirements. In present work, passive cooling technologies such as planform, shading devices, garden trap bond, fenestration, air ducts, earth berming, and indoor gypsum wall finishes, false ceiling etc. had been integrated into building design of a commercial building at Tuljapur in the hot and dry climatic zone of India. Field experimentation work of measurement of temperatures in indoor and outdoor locations of the building had been conducted to assess the cooling potential of these technologies. It was found that average temperature reduction in indoor atmosphere was archived as 3°C except the temperature difference between indoor and outdoor atmosphere. This was a cumulative effect of above mentioned passive cooling technologies integrated in building design.

“…In designing a sustainable building to accomplish passive and low-energy usage, there are many strategies using rainwater that can be adopted (Sun et al, 2013). However, the easiest applicable strategy that can be applied involving low cost in terms of installation and maintenance is to create pleasant environment using natural resources like rainwater (Macias, Gaona, Luxan, & Gomez, 2009) . Many scholars agreed that , it is wise to implement various systems for passive cooling strategies in a building which highlight the usage of rainwater as its main source like the usage of roof pond with water collected from rainwater (Spanaki, Tsoutsos, & Kolokotsa, 2011), provide ample space for roof garden that is watered by rainwater harvesting (Saadatian et al, 2013), have water hardscape and softscape obtained from rainwater by integrating it with building structural elements (Daglio, 2014) as well as have cooling wall run by rainwater flow at strategic exterior locations (Castell, Martorell, Medrano, Pérez, & Cabeza, 2010).…”

Performance of workers in terms of productivity level is determined by many related factors including a comfortable work space. Nevertheless, the discussion on the condition of work space environment namely in low rise office buildings and its related issues on thermal comfort in Malaysia are fairly new and is not well addressed. Past studies indicate that low rise offices found in many well-developed countries tend to utilize air conditioning as easiest ways to create a comfortable work space and to cool down the building interior. This factor had indirectly contributed to the increment of energy consumption namely in urban areas due to the rise of air condition consumption from 40% to 60% annually. As a result, contributed to the formation of urban heat island (UHI) which affect community’s environment and quality of life involving health and comfort. The objective of this paper therefore is to discuss and propose approaches on how to apply rainwater elements in architectural design for achieving thermal benefits through passive cooling. This is vital as Malaysia receives large amount of rainfall throughout the year in which this nature resources may provide advantages as sustainable source in cooling down the building temperature. For this purpose, case study as research strategy is adopted using mixed methodology combining qualitative and quantitative method. To conduct the data analysis, ECOTECT simulation and small field experiments are performed to investigate the cooling effect in low rise office building. Findings indicate that low rise office building which integrates rainwater elements in architectural design potentially improve the building thermal performance thus reducing building’s energy demand for space conditioning. This study is important as by adopting appropriate methods in addressing ecology issues will not only provide a comfortable living environment to the users but also established referential guideline in low rise office design.
