# Adaptation of the SBTool for Sustainability Assessment of High School Buildings in Portugal--SAHSBT
## 3 Materials and Methods
#### Categories and Indicators
This indicator in the SAHSBP\({}^{\text{PT}}\) methodology is assessed using a form that evaluates the commission team; the documentation regarding energy and the building system; the schedule that defines the important dates and milestones and the budget for the purchase and installation of energy generation for the building; the plan for the management of mechanical systems; and performance verification. **C4. MATERIALS, SOLID Residues, AND Resources Management**  
The construction industry is one of the largest generators of solid waste. The production of waste occurs during construction, demolition, and use by the occupants. This category includes three indicators: \"reuse and recycle materials\" (I8); \"environmental management plan\" (I9); and \"flexibility and adaptability\" (I10). **Indicator 8--Reuse and Recycling of materials**  
The objective of this indicator is to support and reward the use of reused materials and the use of materials with recycled content in the building. This indicator is the intersection of the indicators of \"reused materials\" (I10) and \"recyclable materials\" (I11) used in the SBTool\({}^{\text{PT}}\)-STP for Office Buildings. This indicator in the SAHSB\({}^{\text{PT}}\) methodology concerns the value corresponding to the sum of the cost of the materials or elements in the construction that are pre-existing in the building and will be reused and the materials or construction elements from deconstructions located outside of the site that will be reused. The reference practices and method of calculation for this indicator are the same as those used in SBTool\({}^{\text{PT}}\)-STP for Office Buildings. **Indicator 9--Environmental management plan**  
The objective of this indicator is to support the appropriate management of resources during the use phase of the building and/or the adoption of an Environmental Management System (EMS). This indicator in the SAHSB\({}^{\text{PT}}\) methodology is assessed using a form that evaluates the environmental management system; monitoring systems; product consumption in the use phase; and the training of occupants. This indicator is similar to that used in the SBTool\({}^{\text{PT}}\)-STP for Office Buildings. **Indicator 10--Flexibility and adaptability**  
The objective of this indicator is to promote the adoption of construction solutions and processes that facilitate the changing uses of the building in repair work and decommissioning. Flexibility and adaptability are new subjects that have not been used widely in the planning of high school building construction. This indicator in the SAHSB\({}^{\text{PT}}\) methodology is assessed using a form that evaluates the modularity of compartments, ventilation systems and air conditioning (duct location and size of equipment), water system and plumbing (location), and electrical and communications system (duct location). The reference practices and method of calculation for this indicator are the same as those used in the SBTool\({}^{\text{PT}}\)-STP for Office Buildings. This indicator is similar to those used in the SBTool\({}^{\text{PT}}\)-STP for Office Buildings and SBTool\({}^{\text{PT}}\)-H.  
**C5. WATER**  
The choice of suitable materials and equipment in the design phase helps to reduce water consumption. Water consumption should be reduced in the construction phase but especially in the use phase of a building. This category includes three indicators: \"water consumption\" (I11); \"water treatment and recycling\" (I12); and \"collection and reuse of rainwater\" (I13). **Indicator 11--Water consumption**  
The objective of this indicator is to support the decrease of water consumption inside buildings in the use phase, using efficient systems. In the school environment, the main concerns relate to water saving, mainly in lavatories, toilets, and showers.
