اندازه گیری تاثیر طراحی سبز محیط ساختمان بر بازار املاک و مستغلات شهری در تایوان

To address the worsening problems of global warming and the urban heat island effect, ecological cities and building environment greening are being promoted in population-dense urban areas domestically and abroad. For example, the Japanese Ministry of Land, Infrastructure, Transport, and Tourism announced the CASBEE-HI (Heat Island) assessment system in 2008 as a response to worsening urban warming and urban heat island effects. The Ministry implemented “Building Space Greening Plans” in Tokyo, Osaka, and other cities, enforcing by law the effective reduction of urban temperatures and improving urban living environments and alleviating the threat of urban ecological disasters. Therefore, this study integrates Taiwan domestic and foreign building space greening design, derived greening benefits, implementation promotion methods, and greening design policies as measurement constructs to examine the mutual influence between different constructs and to analyze the degree of influence on the urban real estate market. From the result, demonstrating that building space environment greening design does bring about positive benefits. In addition, the greening benefit was shown to have a positive impact on the urban real estate market. At the same time, greening promotion implementation method and urban policy standard both had a positive impact on the urban real estate market, demonstrating that government promotion of building environment greening design through urban design policy means is acceptable to the public.

The study discussed previously [1] showed that sustainable building has a significant positive influence on housing purchase choices and that when sustainable building enjoys a positive appraisal response, housing purchase choices can be increased, thereby effectively increasing interior and exterior residential environment quality, reducing air conditioning use, properly implementing roofing insulation measures and roof greening and ensuring residential sanitation safety. These effects facilitate housing purchase choices. Raymond [2] also noted that the appraisal results or certification of “sustainable building performance” of overall building environments have gradually come to be viewed as the basis for project development, building award awards, as well as risk and real estate mortgage evaluations. One important message from the United Kingdom, Australia, and EU countries regarding standards for real estate evaluation is that they should be closely combined with currently implemented sustainable building assessment tools. This issue has become an internationally important one in real estate markets and in market transformation [3]. To address the worsening problems of global warming and the urban heat island effect, ecological cities and building environment greening are being promoted in population-dense urban areas domestically and abroad. For example, the Japanese Ministry of Land, Infrastructure, Transport, and Tourism announced the CASBEE-HI (Heat Island) [4] assessment system in 2008 as a response to worsening urban warming and urban heat island effects. The Ministry implemented “Building Space Greening Plans” in Tokyo, Osaka, and other cities, enforcing by law the effective reduction of urban temperatures and improving urban living environments and alleviating the threat of urban ecological disasters. The United States has formally incorporated rooftop greening into LEED assessment criteria. Relevant studies have demonstrated that appropriately increasing urban greening or reducing the proportion of artificial structures facilitates the alleviation of the urban heat island effect [5], [6] and [7]. Studies have also demonstrated that plant greening provides the benefit of alleviating urban warming and the urban heat effect [8], providing tangible aid in reducing energy consumption as well as improving optimal energy use; such greening constitutes the optimal implementation in pursuing a sustainable ecological living environment [9] and [10]. In addition, “greening approaches” are the most inexpensive method of reducing temperatures [11]. The greening benefits resulting from space greening of building rooftops, walls, and bases can not only improve overall urban environmental quality, it can also improve the added value of buildings, e.g. increasing asset value, improving image and reputation, and increasing market competitive ability [3], [12] and [13]. In the rapid increase of high-rise buildings in Taiwan, the development behaviors of builders favor the maximum usage benefits of bases; their contributions to environmental greening have been limited to minimum legal standards. Furthermore, the “Green Building Standard Promotion and Usage Operating Points” announced by the Building Research Institute of the Ministry of the Interior does not legally enforce the incorporation of privately-constructed buildings into the range of evaluation. Other relevant greening regulations and policies lack detailed specifications for the greening of the rooftops, walls, and base areas of building environment spaces. Because Taiwan's building green design and urban real estate-related research are few, but this research hopes to obtain views on this topic of the general public, also worried that the general public do not to understand questionnaire question, therefore this text is to investigate the respondents with the basic specialized background of building, real estate, urban plan, and so on, then, the investigation object is not to emphasize specially the years of experience in green buildings. Therefore, the following objectives have been set for this study: 1. To integrate Taiwan domestic and foreign building space greening design, derived greening benefits, implementation promotion methods, and greening design policies as measurement constructs to analyze the mutual influence between different constructs. 2. To examine the influence of the building greening construct on urban real estate markets. 3. To determine the key variables/dimensions of urban real estate markets which are affected by the building greening construct, and provide domestic real estate-related industries and domestic cities with a reference for urban greening laws and policy promotion.

The purpose of this paper was to examine whether greening plans and promotion implementation methods produced an impact on the economic benefits of urban real estate development through greening benefits and greening policy. The following conclusions were reached: 1. Empirical analysis in this study discovered that “Building space environment greening design” was negatively associated with “building costs.” This result suggests that when green building design is promoted in Taiwan in the future, “Greening position,” “Greening area,” “Planting allocation,” and “maintenance and management” of buildings should be first regulated based on greening design constructs (endogenous variables). In particular, the most recognized greening implementation locations such as ground levels, roof levels, and balconies should be used as the basis for building construction and maintenance costs. 2. Also, “Building space environment greening design” exhibited significant positive association with “Investment benefits” and “Marketability.” In particular, this variable had the greatest impact on “Marketability.” These results suggest that when developers promote architecturally green residence products, they should incorporate “Improvements in building image” and “Increases in market competitiveness” into marketing considerations. 3. The research hypotheses introduced in this study were supported by empirical testing and were demonstrated to indicate significant positive impacts, showing that green architectural space environment design do have positive benefits, consistent with our review of literature. Greening benefits exhibit a positive significant impact on urban real estate markets, a result consistent with the results of related domestic and foreign studies. At the same time, greening promotion implementation methods and urban policy regulations also had positive impacts on urban real estate markets, showing that governments can consider “Building greening regulations” in promoting green building and environment design or in “Urban design policies.” For example, governments can independently establish legal regulations and strengthen the quality of life benefits brought by greening, such as effective microclimate environment adjustments, creation of good leisure spaces and scenery, and improvements to air quality.
