Commercial building owners and operators have requested a standard set of key performance metrics to provide a systematic way to evaluate the performance of their buildings. The performance metrics included in this document provide standard metrics for the energy, water, operations and maintenance, indoor environmental quality, purchasing, waste and recycling and transportation impact of their building. The metrics can be used for comparative performance analysis between existing buildings and industry standards to clarify the impact of sustainably designed and operated buildings. The building features can be used to normalize the building performance metrics for comparative analysis. A companion document titled Assessing Sustainability: Protocol to Measuring Building Performance provides the details on how to apply the metrics to a specific commercial building.
The document details specific items within each area, both inside and outside. Items such as:
- Indoor/outdoor energy use
- Landscaping energy use
- Owner generated energy production
- Indoor/outdoor waste water collection
- Building liability costs
- Churn costs
- Janitorial services
- Grounds maintenance costs
- Occupant satisfaction – everything from temperature to privacy
- Recycled material costs
- Landscape debris costs
- Office material purchases
- Mode of transportation ratio
- Fleet vehicle Greenhouse Gas emissions
