block , but because they are 18 to 25 storeys high , they provide insufficient ventilation and very little daylight except on the top two floors . Casement windows are commonly used , which mean that the occupants must add additional grill openings to protect against falls or to provide added security . In addition , some of the house units have windows that open to a maximum of a 30 ° swing , which is still large enough for a child ’ s body to pass through ( CIDB Malaysia , 2020a ).
As a result , the Construction Industry Development Board Malaysia ( CIDB ) initiated a project to improve affordable housing by embarking on research with the Construction Research Institute of Malaysia ( CREAM ) and industry players on DeLIGHT Homes : A Sustainable and Innovative Affordable Housing Design . DeLIGHT Homes serve as a resource for housing players , designers , and the Government , as well as to assist developers and policymakers in providing quality affordable housing . The elements of sustainability and
inclusive design , technological advancement and innovation capability , integrated process designing , and affordable housing planning will increase the likelihood of the project ’ s success .
Elements of sustainability in home design are highlighted in Figure 2 . These include the following elements : 1 . Environmental Sustainability 2 . Social Sustainability 3 . Economic Sustainability
Growing awareness of the cost and environmental impact of high energy use has made passive ventilation , also known as natural ventilation , an increasingly attractive method , especially in sustainable housing building design . It can keep good indoor air quality , a healthy and comfortable indoor climate . Ventilation strategies such as building position , wind exposure , location of entrances , and others are aimed at ensuring that the amount of fresh air moving through the
