“…The negative impacts of physical contributors on occupants' health during the operational phase of building can be initially neutralized through considering healthrelated design principles during the building's design phase. The building's orientation (Abanda and Byers 2016;Mangkuto, Rohmah, and Asri 2016), felicitous selection of building materials in accordance with local climate (Mirrahimi et al 2016), application of passive techniques in building envelope such as passive walls (Bellos et al 2016;Omrany and Marsono 2016) are some preliminary measures that can be taken during the design phase in order to preclude the occurrence of physical contributors.…”

Health and well-being are vitally important aspects of people centric building design and are the roots of productivity. Sick building syndrome (SBS) is a collection of factors that can negatively affect physical health in several ways. Besides physical health is also related to psychological well-being because the human body is one interactive biological system. This paper focuses on reviewing the current state of knowledge on building sickness syndrome which has been prevalent as a building illness since the 1970s especially in offices and schools. While the concepts of intelligent, smart and sustainable buildings have gained considerable attention during recent decades, there is now increasing attention being given to designing healthy buildings. This study provides a review about SBS symptoms. Several negative effects of SBS are identified and potential solutions are advocated. Finally, the study stresses the role of built environment and concludes that ongoing research towards tackling SBS and developing healthy indoor environments should not be limited to a single formula as any health-related building design approach is dependent on several interacting factors.

“…Besides that, it is important to control passive design strategies in a building as this approach will influence the energy performance of a building such as natural lighting, heat gain, shading, and envelope conduction. Omrany & Marsono, 2016). This view is further supported by Aelenei et al,(2013), that the passive design strategies in buildings should be appropriately orientating building towards solar heating maximization when buildings are dealing with heating challenges.…”

These days, the topic on the sustainable building has become one of the most important concerns in the academic studies, construction industries, as well as governmental agencies. Sustainability in the building sector has raised the attention towards a new concept called net-zero energy buildings (NZEBs). With regards to the development of Malaysia's buildings sectors, the government has realised the undesirable effects of inefficient of energy usage by demonstrating their efforts in Construction Industry Transformation Programme (CITP) 2016-2020. Commonly, healthcare buildings are among the greatest energy consumers of any institution and the extensive use of various medical equipment, mechanical ventilation of this building has caused a high level of carbon emission. Hence, by concentrating on these issues, NZEBs become an important concept to be implemented in healthcare buildings. However, the awareness of NZEBs in Malaysia is still low and the construction industry in Malaysia still unaware of NZEBs. This paper aims to investigate the current design practices of healthcare buildings in Malaysia as well as the architect's understanding of NZEBs through preliminary investigation among architects. Literature was reviewed and pilot studies by using semi-structured interviews were conducted. The results uncover that some green practices related to the design practices in healthcare buildings has been carried out and some of these practices are similar to the NZEBs design practices even though the term of 'NZEBs' is not being used. It is predicted that the paper will provide a basic knowledge for future research in NZEBs for healthcare buildings, challenges of NZEBs implementation and designing NZEBs for healthcare buildings in Malaysia.

“…Usually, higher energy consumption in residential buildings is associated with climate change between cold and hot environments. Therefore, many efforts are conducted to reduce the energy consumption in buildings by several means such as developing and improving thermal insulation systems and renewable energy systems, which attracted many researchers and related industries, to enhance the science of energy efficient buildings . The scope of this article falls within the improvement of energy efficient buildings by improving their thermal insulation systems.…”

The present study investigates the use of two air cavities thermal insulator in buildings. The two air cavities insulator structure is supposed to be located within the building's wall and roof forming two separated vertical and horizontal cavity, respectively. In addition, the wall cavity height (or roof cavity length), H, was investigated at H = 2, 3, 4, 5 m to find the influence of wall cavity height (or roof cavity length) on various thermal characteristics and thus to determine the thermal optimum thickness. At each wall cavity height (and roof cavity length), cavity thickness, Lc, was varied from 0.01 m to 0.1 m forming aspect ratio, AR = H/Lc ranges of 20 to 200, 30 to 300, 40 to 400, and 50 to 500 for H = 2, 3, 4, and 5 m, respectively. The present results reveal the presence of the first and second cavities in wall and roof at various thicknesses affecting the development of wall and roof components' surface temperature. In addition, varying the wall cavity height or roof cavity length has further significant effects on the development of these surface temperatures. Moreover, it was found that increasing the wall cavity height leads to increasing the optimum wall cavity thickness, Lc = 0.024, 0.027, 0.029, and 0.031 m at cavity height, H = 2, 3, 4, and 5 m, respectively, whereas in the roof cavity case, the optimum roof cavity thickness seems to reach its asymptotic value at about 0.019 m for the roof cavity length investigated, H = 2, 3, 4, and 5 m despite the optimum wall cavity thickness that was not.
