Tool Comparison

Powered by machine learning, cove.tool is an easy-to-use platform that helps architects, engineers and contractors optimize sustainability and energy efficiency while saving on project costs. By automating the tedious task of energy modeling, cove.tool eliminates the need for manual labor, cutting what once took consultants 150 hours to do manually into just 30 minutes.

Sefaira’s analysis is nimble enough to keep up with the pace of conceptual and schematic design. Run full annual simulations powered by industry-accredited analysis engines, and get your building performance results in minutes instead of weeks.

The metrics you need
Energy use and carbon emissions
Understand your design’s impact on energy cost and CO2 emissions while also measuring the potential impact of a renewable system.

Thermal comfort
See how shading improves operative temperatures and measure the impact of window openings on air temperature.

Daylight
Choose between Daylight Factor, Direct Sun Exposure, and Annual Daylight outputs (including Spatial Daylight Autonomy sDA).

HVAC
Quickly assess the impact of your architectural features on HVAC sizes and generate preliminary sizes to improve cost estimation.
