Option 1

PRM Table

This is a sample building energy performance and cost summary using the Performance Rating Method (PRM). Electricity and natural gas use should be broken down by end uses including space heating, space cooling, lights, task lights, ventilation fans, pumps, and domestic hot water, at the least.

Energy Simulation Narrative

Sometimes the energy simulation software being used to demonstrate compliance with Option 1 doesn't allow you to simulate key aspects of the design. In this situation you'll need to write a short sample narrative, as in these examples, describing the situation and how it was handled.

Site Plan – Parking Meeting Local Zoning Requirements

Document Option 1 with a site plan like this one, showing parking meeting but not exceeding local zoning requirements.

Narrative – Water Use Reduction

Use a narrative like this to demonstrate a 50% reduction in potable water use.
