Back-of-the-Envelope calculator

Back-of-the-Envelope calculator

Our Back-of-the-Envelope calculator is a learning tool that allows anyone to interact with a building as an energy system. You can see real-time energy connections between building components, isolate the effects of changing a single energy parameter, or produce concept-level energy and CO2 emissions estimates. When it comes to building energy consumption, nearly everything affects everything. It's very difficult to get a feel for energy efficiency among the complicated interactions. More
EUI Analyzer

EUI Analyzer

This tool compiles publicly available data on actual building performance alongside industry references. It supports EUI goal-setting for projects that integrate an energy performance target. With this knowledge, users can make informed decisions on future and current building performance standards. More
hybrid ground-coupled heat pumps

HyGCHP Modeling Tool

Reduce the cost of implementing geothermal heat pump systems on your building projects by going hybrid. A hybrid geothermal heat pump system can lower your costs by reducing the peak capacity of your ground loop and allowing you to install a smaller, less expensive ground heat exchanger. HyGCHP is a software module that can help you analyze this option! More
