Description of the tool
GBTool is intended to be used for the assessment of potential energy and environmental performance of buildings. It can handle both new building and renovation projects within the three types of buildings it assesses: Multi-unit residential; Office and School. The GBC process is managed by iiSBE , the International Initiative for a Sustainable Built Environment.
GBTool provides approximate assessments of a broad range of potential environmental performance parameters, all related to performance benchmarks that are relevant to the region and building occupancy. Although GBTool performs various internal calculations, it is primarily designed to act as a framework for scoring and weighting, using data generated in external models to perform detailed studies. GBTool is implemented in Excel 2000.
In GBTool, scores are assigned in a range of -2 to +5, where:
There are four levels of parameters included in the system, including in descending order of generality, Issues, Categories, Criteria and Sub-Criteria. The Issues and Category parameters are voted on by team members in the Vote worksheet, but the two lowest levels are assigned automatically. Scores are multiplied by the weights and the weighted scores are shown in the Results worksheet.
