One of the critical issues that many authors (cf. as an example, Carmody et al., 2009; Mateus et al., 2011; Chew, 2010) recognized in the debate on the Green Building Challenge (GBC) evaluation models by the International Initiative for a Sustainable Built Environment (iiSBE) is that they mainly focus on the energy and environmental performance of buildings, being improvable in the consideration of the social and economical dimensions of sustainability in their assessment framework. From one side, it is broadly acknowledged that the increasing complexity of the decision making process encourages the involvement of different stakeholders in the evaluation procedures and tools, on the other side, the recent economical trends require a stronger measurement of the economic and financial performance of projects, both for public and for private investments. Furthermore, the growing interest in sustainability increases the need for developers, investors, tenants and government bodies of clarifying whether and how much the sustainability features affect the property value. The balance between costs and benefits, indeed, is a crucial decisional principle under a public perspective, but it might become a decisive leverage reason for private business, too. According to these general assumptions, the paper gives a critical review of appraisal methods and tools developed by the GBC process in the field of the performance assessment of buildings, in order 1) to point out their strengths and weaknesses and 2) to understand the opportunity of integrating sustainability issues into property decisions with the aim of appropriately quantifying the value of sustainable property investment and of improving the degree of transparency in the decision-making process about green buildings. With reference to the outcomes of this analysis, the paper suggests to develop the last version of the Green Building evaluation tools, the Sustainable Building Tool (SBTool 2012).

Abstract
One of the critical issues that many authors (cf. as an example, Carmody et al., 2009; Mateus et al., 2011; Chew, 2010) recognized in the debate on the Green Building Challenge (GBC) evaluation models by the International Initiative for a Sustainable Built Environment (iiSBE) is that they mainly focus on the energy and environmental performance of buildings, being improvable in the consideration of the social and economical dimensions of sustainability in their assessment framework. From one side, it is broadly acknowledged that the increasing complexity of the decision making process encourages the involvement of different stakeholders in the evaluation procedures and tools, on the other side, the recent economical trends require a stronger measurement of the economic and financial performance of projects, both for public and for private investments. Furthermore, the growing interest in sustainability increases the need for developers, investors, tenants and government bodies of clarifying whether and how much the sustainability features affect the property value. The balance between costs and benefits, indeed, is a crucial decisional principle under a public perspective, but it might become a decisive leverage reason for private business, too. According to these general assumptions, the paper gives a critical review of appraisal methods and tools developed by the GBC process in the field of the performance assessment of buildings, in order 1) to point out their strengths and weaknesses and 2) to understand the opportunity of integrating sustainability issues into property decisions with the aim of appropriately quantifying the value of sustainable property investment and of improving the degree of transparency in the decision-making process about green buildings. With reference to the outcomes of this analysis, the paper suggests to develop the last version of the Green Building evaluation tools, the Sustainable Building Tool (SBTool 2012).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
