Sketchbox: Your trusted energy modeling tool

Great design starts with a sketch

Our mission is to accelerate climate solutions for everyone. Great building design, informed by early energy simulation, has the power to improve building performance without adding cost. Every project is constrained, so how can we make the best design decision every time, as quickly as possible?

Conventional energy models are too slow or expensive to inform concept design, so only the most expensive and high-profile buildings have been getting the analysis they deserve. That's where SketchboxTM comes in - by simplifying and streamlining the energy modeling process, we're enabling projects of all shapes and sizes to be more climate friendly.

Designed to be responsive to your needs

Sketchbox is a web-based user interface for energy modeling, designed to take the guesswork out of energy performance and help you find the right solutions faster. We built it to meet a need within our own team of full-time energy engineers and realized that we had something worth sharing. 

Sketchbox is different because it focuses on the concept design process and helps designers quickly identify opportunities that matter most in any given project. You don’t need to be an energy expert to be able to create change. We built it to be:

  • Simple – Sketchbox minimizes the use of complicated industry terms and helps you move intuitively through a project using good default values and suggested energy efficiency strategies that apply to the most common types of buildings and HVAC systems.
  • Fast – Sketchbox purposely simplifies geometry, avoiding the most time-consuming aspect of modeling, and leverages the speedy and reliable Department of Energy DOE-2 modeling engine.
  • Robust – Run time errors can derail a concept design session. Sketchbox is designed to be reliable with results that are accurate enough for early phase design, simple buildings, and energy efficiency programs. Users can download native DOE-2 files to understand the inner workings of Sketchbox.
  • Actionable – Measure-by-measure results help you focus on the design elements that matter most, while minimizing post-processing time.
  • Mobile – You can run Sketchbox from any internet-connected device to make real-time decisions with your design partners and clients.
