Pilkington Sun Angle Calculator

The Sun Angle Calculator is a handy tool that provides a relatively simple method of determining solar geometry variables for architectural design, such as designing shading devices or locating the position of the sun relative to a particular latitude and time.

Pilkington Glass has kindly granted permission to SBSE to reproduce and distribute the Pilkington Sun Angle Calculator. This is a fantastic graphical design and analysis tool beloved by thousands of architects and engineers. Information on ordering copies of the Sun Angle Calculator and accessing the online manual "Designing with the Pilkington Sun Angle Calculator" will be found on the

Regeneration-Based Checklist for Design and Construction

The SBSE version of the Malcolm Wells Wilderness-Based Checklist for Design and Construction is available in multiple languages. Environmentally sensitive construction is a global issue, perhaps an existential issue.

A Regeneration-Based Checklist for Design and Construction

If you would like to volunteer to translate the checklist into another language, download the original Excel version. Please send the translated version to Bruce Haglund for posting. Please have at least one other person check your translation to ensure accuracy.

Carbon-Neutral Design Project

The Carbon Neutral Design Project is a joint effort between members of SBSE, the AIA, and a private donor to provide practitioners, faculty, and students with the means to meet the 2030 Challenge.

The Carbon Neutral Design Project is a joint research effort between members of the Society of Building Science Educators (, the American Institute of Architects (, and a private donor, the purpose of which is to provide practitioners, faculty, and students with the means to meet the 2030 Challenge  (, that is, to be able to design and construct buildings to a state of carbon neutrality by th

Solar Decathlon - Building Science Education Series

The Solar Decathlon Building Science Education series is designed to educate students and working professionals on building science principles that are paramount to the successful design of high-performance, energy-efficient buildings.

Instructional content is presented in modules, covering specific topics. Altogether, this series aims to educate viewers on:

FEMA Building Science Resource Library

The Building Science Resource Library contains all of FEMA’s hazard-specific guidance that focuses on creating disaster-resistance communities. You can search for a document by its title, or filter the collection to browse by Disaster Type and Audience.

CBE Climate Tool

The CBE Clima Tool is a web-based application built to support climate analysis specifically designed to support the need of architects and engineers interested in climate-adapted design.

The CBE Clima Tool allows users to analyze the climate data of more than 27,500 locations worldwide from both Energy Plus and You can, however, also choose to upload your own EPW weather file. Our tool can be used to analyze and visualize data contained in EnergyPlus Weather (EPW) files. It furthermore calculates a number of climate-related values (i.e.


Solar-2 plots sunlight penetrating through a window with any combination of rectangular fins and overhangs.

SOLAR-2 also plots hour-by-hour 3-D suns-eye view movie of the building wall. Prints annual tables of percent of window in full sun, radiation on glass, etc. NOTE: Many of its functions have also been added to HEED, SBEED, and Climate Consultant.


CLIMATE SCOUT helps its users design buildings that uniquely respond to a site by providing climate-specific design advice at the building scale. It pairs the Köppen-Geiger climate classification and building design strategies from Architecture 2030’s Palette.


Virtual Green Building Tours for Safe Inspiration

Building tours: they’ve been a vital educational component of green building from day one. But now COVID-19 has made them unsafe. Thanks to the Sustainability Leader Peer Networks we help convene, BuildingGreen has compiled a list of online tours and other videos that you can view from the safety of home.


A U-value, Time Lag, and Decrement Factor calculator opaque wall or roof surfaces.

OPAQUE calculates the U-value, Time Lag, and Decrement Factor for wall or roof opaque surfaces composed of a single or multiple layers. These can be used to calculate the Heat Gain or Loss through the surface. Composite surfaces are constructed by the user from a library of materials and displayed in two or three dimensions. In addition, 2-D plots of Outdoor and Sol-Air Temperatures, Radiation variables, and Heat Gain/Loss through the envelope can be displayed.
