There are many great resources available for ZNE and energy efficient building. Some of them are listed below.


OpenStudio is a cross-platform (Windows, Mac, and Linux) collection of software tools to support whole building energy modeling using EnergyPlus and advanced daylight analysis using Radiance.

BEopt (Building Energy Optimization) software provides capabilities to evaluate residential building designs and identify cost-optimal efficiency packages at various levels of whole-house energy savings along the path to zero net energy.

National Renewable Energy Lab’s (NREL) PVWatts Grid Data Calculator estimates annual energy production and performance data for solar PV based on typical meteorological year weather data.

NREL’s System Advisor Model (SAM) is a performance and financial model designed for renewable energy projects and industry professionals.
