Thermal Comfort Tool

CBE tools and packages

This page contains a list of tools and packages developed by the Center for the Built Environment (CBE), University of California Berkeley.

CBE Radiant Tool

The CBE Rad Tool is an interactive web-based design tool for the early of high thermal mass radiant systems. The primary aim of this design tool is to provide an interface for estimating the performance of high thermal mass radiant system under steady-state and transient conditions.

CBE Spatial Thermal Comfort Tool

Graphical visualization for spatial resolution of mean radiant temperature (MRT) within a space, based on room surface temperatures, solar gain through windows and skylights. Enable input of thermal comfort variables such as clothing levels and metabolic rates.

CBE Fan Tol

A tool that allows designers to quickly select and layout ceiling fans in a room to meet their desired airspeed requirements, and to facilitate incorporation of fans into designs.


Python package to calculate several thermal comfort indices.

UFAD Cooling Load Design Tool

A simplified, practical design tool to determine cooling load requirements, airflow rates and temperature stratification for Underfloor Air Distribution (UFAD) systems in interior and perimeter zones.
