Determining sustainable design management using passive design elements for a zero emission house during the schematic design

Abstract

16There is an increasing trend toward building energy-saving and zero-carbon-emission house 17 worldwide. Even if diverse sustainable technologies have been developed and adopted, existing 18 design strategies are decided intuitively by an expert's qualitative evaluation and not by objective, 19 quantitative design guidelines. The present study analyzes passive design elements (PDEs) from 20 existing sustainable housing projects as a method for quantitative evaluation. PDEs could be suitable 21 methods to house owner who does not have professional knowledge in construction of zero emission 22 house (ZEH). 23 Extracted PDEs are analyzed by an analytic hierarchy process (AHP) to determine which PDEs are 24 applicable for limited budgets. Through the AHP, PDEs are re-sorted based on the order of importance 25 2 weight and predominant 7 PDEs are determined. Due to characteristic of passive house which 26 envelops the house from outside environment, PDEs would be applied before design of house 27 structure. Therefore predominant PDEs could be considered first when the zero emission house (ZEH) 28 is developed. The proposed sustainable design management (SDM) based on PDEs would be 29 profitable for decision-making during the schematic design phase, which is an important stage in 30 selecting suitable design elements in ZEH construction, because environmental engineer or consultant 31 could not be involved from early stage. With the utilization of SDM consisting of PDEs, potential 32 ZEH clients could easily launch their ZEH project without early involvement of sustainable expert. 33Taking account of energy consumption in residential sector, application of SDM has a significant 34 contribution for substantial carbon reduction. 35 36 House. 38 39 Humankind is currently facing an unprecedented challenge, global warming. The building 40 environment is one of the main sources of carbon emissions related to global warming [1]. Since 41 Gunter Pauli's advocacy of the zero-emission concept in 1994, various industries have followed the 42 zero-emission theory. The theory's principles also have been adopted in the construction industry as a 43 concept for a ZEH. According to Mohamed and Alistair [2], reducing the carbon emissions in the 44 housing sector would be an effective way to mitigate global warming. Lee and Burnett [3] also argue 45 that the building sector accounts for 31% of the total energy consumption worldwide, and the 46 residential sector accounts for over half of the energy consumption in the building sector. In detail, 47 according to European Environmental Agency [4], 12% of greenhouse gas emissions are generated 48 only in residential sector. 49 Numerous studies on reducing the carbon emissions have been conducted in the ZEH field. There is 50 mounting literature on the use of hybrid heating, ventilation, and air conditioning (HVAC) systems as 51 one of the main parts of a ZEH [5-6]. Because of advances in technology hybrid HVAC systems are 52 now widely applied in the housing industry, from a single ho...

Study on Green Ecological Property Management Model at Residential Area in China

“…Passive energy-saving technology fully considers features of buildings in the early stage of designing and reduces the use of machinery and electrical equipment, so as to optimize energy-saving effect at operational phase (Whang and Kim 2014). Passive energy-saving costs less than other energy-saving technologies, making it the first choice of its kind (Qing and Zengwen 2006).…”

Judicious choice of the building compactness to improve thermo-aeraulic comfort in hot climate

“…Therefore, several elements, such as southern window and northern façade insulation, natural ventilation, zoning plan elements, should be considered and determined during the schematic design phase. As these kinds of elements strongly influence building shape and size, they are directly related to construction costs as well as energy performance [10]. In [11] it is proved that generally, annual energy consumption increases as the courtyard building shape gets longer as a direction of prevailing wind.…”
