About the Tool

What can Emodeler do for you?

Using easily attainable data on your buildings (like year-of-construction), Emodeler taps into established research to assemble a virtual building portfolio to represent any collection of buildings. It simulates the buildings’ energy-usage using local weather data. This hourly simulation calculates the energy, cost, and carbon savings expected from either common or customized energy efficiency improvements to the buildings.

How are we different?

Emodeler is a process innovation. We’ve wrapped up the complexities of building energy modeling, previously only accessible to energy engineers, into a simple app that anyone in the building industry can use.

Streamlined or Custom

Specific heat pump? Generic LED upgrade? There is a process built for you. Emodeler inputs are made to be streamlined in minutes, but also have flexibility to precisely approximate complexity if the use case permits.

Frequently Asked Questions

It depends on how much the user knows about the building. With Tier-1, An average building of the same age-range, climate, size, and type will be used. If your building is average, this is a good approximation. With Tier-2, any information you know about the building can be used to increase accuracy, including data about occupancy, building materials, HVAC systems, lighting, and more.

No. All complication is hidden behind the UI. The user interacts with a web form which requires only high level information about the building. The tool only requires that the user is aquainted with the most imporant building details.
