## 1 Introduction
### The Multi-Method Approach  
The SBTool Urban instrument--\"Sustainable Building Tool Urban\"--developed by the Building Physics and Construction Technology Laboratory (LFTC-UM), Portugal, and the company Ecochoice SA, has devised a method based on the SBTool and urban community assessment. This instrument presents management and urban planning parameters, aiming to provide improvements in the quality of life in the city [3]. The method is based on the main international assessment methodologies, such as BREEAM communities and LEED for neighborhood development. SBTool Urban adopts quantitative assessment procedures, which are flexible and adaptable to the reality of the Brazilian construction market. The evaluation structure comprises indicators grouped into categories based on the similarity of the subjects covered. The categories are grouped into three dimensions, which are environmental, economic, and social issues. The analysis process consists of adopting references to sustainable practices of real estate developments, which are called benchmarks. These benchmarks serve as a comparison model to verify obtained values by the main object of study. The comparison between SH projects with the benchmarks aims to establish a reference that presents best practices for certain factors related to the environmental impact on society and the economy. Thus, after defining the score through comparison, the sustainability indicators undergo a normalization process in order to standardize the obtained values for the same scale, which align with international standards [13]. Thus, the standardization process establishes that values closest to 1 are considered the best assessments, while those closest to 0 are interpreted negatively. A proposal for the association of values is presented below according to the SBTool (Table 1) international methodology, followed by Equation (1) to develop the normalization calculation. Equation (1): Normalized indicators--Formula from Diaz-Balteiro:  
\[\overline{Pi}=\frac{Pi-P^{*}i}{Pi^{*}-P^{*}i}\]

\begin{tabular}{c c} \hline \hline
**Association of SBTool** & **Values** \\ \hline Unacceptable practice & \(-1\) \\ Acceptable practice & \(0\) \\ Good practice & \(3\) \\ Best practice (benchmark) & \(5\) \\ \hline \hline \end{tabular}
\end{table} 
Table 1: Association of values—proposed by Sustainable Building Tool (SBTool). where: \(\overline{Pi}\) = Normalized result; \(Pi\) = Obtained Score; \(P^{*}i\) = Worst practice; \(Pi^{*}\) = Best Practice (benchmark). Source: [3]. In the final phase, the values are aggregated from a weighted sum process for global classification that varies from E to A + according to the sustainability degree achieved by the studied SH project. The weighting table helps to define the most relevant characteristics of the SH project that influence the impact measurements identified in the region in question. By doing this, the urban conditions of the area can be reviewed to attribute a greater or lesser percentage of impact, as these are more or less significant for the evaluation of a given indicator. Finally, the results are accounted for by each indicator when calculating the weight in the project's score. The local effect has a corrective function regarding the final result. Thus, an indicator that may present a certain natural behavior may have greater or less relevance in specific situations. This higher or lower influence is expressed by adding 5% or 10% over the final value or by subtracting those same percentages when the interpretation of the effect is small (\(-\)5%) or very small (\(-\)10%). When the effect of the indicator is considered average, no adjustment to the acquired value is considered. Table 2 shows the sustainability gradation adopted. As shown in Table 3, the following aspects are reviewed, to which values are assigned according to the intensity of the analyzed impacts: the extent of potential effects (A), duration of potentials (B), potential intensity (C), the primary system directly affected (D), and local effect.
