Design better performing buildings.


All the analysis you need


Track valuable performance metrics such as Energy Use Intensity (EUI) and see what factors are impacting your annual energy use.


Use key daylight metrics such as Spatial Daylight Autonomy (sDA), Annual Sunlight Exposure (ASE), Direct Sunlight, Annual or Date and Time, and Daylight Factor to analyze and visualize your building’s daylight, reduce glare, and optimize natural light.

Thermal comfort

Understand how glazing, shading, and natural and mechanical ventilation impact the comfort of your spaces using sensitive metrics such as Operative Temperature and Predicted Mean Vote (PMV).

HVAC sizing

Understand how peak loads such as heating and cooling are impacting your plant sizing and find passive and active strategies for reducing them.

Analyze and iterate fast

Analyze and iterate fast

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

Make smart design decisions

Make smart design decisions

You do the design, we’ll show you how factors such as massing, layout, and façade design affect the metrics that matter to you. Whether your goal is to achieve a net zero energy design or a smaller HVAC system, Sefaira’s results will help you steer your project in the right direction.

Get Consesnsus

Get consensus

Share what you’ve discovered with your team or clients, and use compelling visuals to convince them of the performance merits of your design.

Why should I care about building performance?

Four years ago, I transitioned from designing million-pound residential architecture projects in London to the world of sustainable design.

Growing your firm's design capabilities

SmithGroupJJR’s success with performance-based design comes from a very basic, yet powerful, approach: they simply practice it early and often.

Delivering a high performing school design

Stantec’s design for the Olathe High School in Olathe, Kansas (US) successfully accommodates a unique and complex building program, while simultaneously achieving ambitious energy and daylighting.
