The National Australian Built Environment Rating System (NABERS) is a performance-based environmental impact rating system for existing buildings. Based on the analysis of real data, the tool allows to understand the environmental performance of any building – from offices over hotels to hospitals, from retail establishments over data centers to apartment buildings. The assessments are undertaken by independent assessors and audited by the government. Thereby, the tool facilitates smart and informed environmental decision making of developers, asset managers, and even tenants.

The National Stormwater Calculator (SWC) is a software application that allows users to analyze site hydrology for small- to medium-sized locations (less than 12 acres) in the United States and Puerto Rico. The SWC estimates the annual amount of stormwater runoff, based on local soil conditions, land cover, and historic rainfall records and including different development and control scenarios. A cost estimation module and a future climate scenario module are included. The SWC is a resource for all Rainwater Management Credits in LEED by the U.S. Green Building Council for all project types in all rating systems.
