Using easily attainable data on your buildings (like year-of-construction), Glimpse 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.
Glimpse 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.
Specific heat pump? Generic LED upgrade? There is a process built for you. Glimpse inputs are made to be streamlined in minutes, but also have flexibility to precisely approximate complexity if the use case permits.
Are you working on an automated workflow, or a web application? No problem. Glimpse can be accessed as an API or a web form. If you have an existing tool, Glimpse can provide calculations in a fraction of a second to pass on to your interface.
The tool is optimized for large and intensive simulations. Returns results in minimum time
The tool is powerful but straight forward and simple to use.
All simulation results are stored in the cloud and are one click away from your access.
Get a complete and detailed analysis, comparable with an engineer's savings report.
The web tool can be accessed and used from anywhere.
Whether you manage a building or provide efficiency technology, Glimpse helps your bottom line.
Calculating cost and carbon savings due to wholistic retrofit scenarios for your city or district. We have the flexibility to deal with a wide array of data availability.

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.
A digital twin is created of the building's energy using processes, using the industry-standard program for such things: EnergyPlus. The building's operation is then simulated for an average year with and without the efficiency measure in question. The difference is calculated and presented
Rules of thumb, such as "LED's can save 50% of lighting energy," are often used in our industry. These are an average over all building types, and are often exaggerated. Glimpse's digital twin is a representation of your building, and therefore much more accurate than a rule of thumb.
Engineers typically use spreadsheet calculations for these projects. Energy models are generally considered more accurate than spreadsheet calculations, but they are not widely used because the level of effort required to create them. Glimpse is the result of engineers breaking this barrier.
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.
Glimpse Tier-1 requires four inputs: year of construction, square footage, building type, zip code, and optionally heating fuel. The rest of the building is modeled using U.S. averages for the given combination of inputs.
Every year, EIA publishes average utility costs by state for electricity and different heating fuels. They also publish yearly emissions factors associated with electricity from the grid in each state. Glimpse uses the most recent of these values for the corresponding state.
One of the main value propositions of Glimpse is that it is independent of influence from either building owners or technology providers. Our energy models represent the reality of each technology and each building, so that both parties can make decisions based on clear, independent predictions.
