BEopt

Introduction

Expected Learning Outcomes

1. Identify building components affecting building energy use.

2. Identify engineering models for modeling some building components defining energy performance.

3. Use software, supported by the Department of Energy, for the simulation of buildings.

4. Use climate files on simulation of buildings.5. Analyze options for reducing energy

consumption in buildings.

The BEopt™ (Building Energy Optimization) softwareprovides 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.

BEopt provides detailed simulation-based analysis based on specific house characteristics, such as size, architecture, occupancy, vintage, location, and utility rates. Discrete envelope and equipment options, reflecting realistic construction materials and practices, are evaluated.

BEopt uses existing, established simulation engines (currently DOE2.2 or EnergyPlus). Simulation assumptions are based on the Building America House Simulation Protocols.
