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

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 (www.sbse.org), the American Institute of Architects (www.aia.org), and a private donor, the purpose of which is to provide practitioners, faculty, and students with the means to meet the 2030 Challenge  (www.architecture2030.org), that is, to be able to design and construct buildings to a state of carbon neutrality by th

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.

OPAQUE 3

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.

SBEED: Small Building Energy Efficient Design

SBEED is a user-friendly energy design tool shows how much money you can save by making changes for a small (commercial) building .

This new easy-to-use Design Tool starts by automatically creating a reference small non-residential building that meets California’s Energy Code. Then it automatically creates a second building that is usually about 20% more Energy Efficient. You can then copy either one and revise its design and compare it with prior versions of up to nine different designs. SBEED shows you graphics of how much energy and money and carbon you can save by trying various new Design options or by making Remodeling changes or adding Additions to your existing building.

HEED: Home Energy Efficient Design

HEED is a user-friendly energy design tool shows how much money you can save by making changes to your home.

This new easy-to-use Design Tool starts by automatically creating a reference house that meets California’s Energy Code. Then it creates a second home that is about 30% more Energy Efficient. You can design and compare up to nine different homes. HEED shows you graphics of how much energy and money and carbon you can save by trying various new Design options or by making Remodeling changes to your home. You can easily draw in the floor plan of your house, then click and drag windows to their best location on each wall.

Climate Consultant

Climate Consultant is a simple to use, graphic-based computer program that helps architects, builders, contractor, homeowners, and students understand their local climate.

Climate Consultant uses annual 8760 hour EPW format climate data that is made available at no cost by the Department of Energy for thousands of weather stations around the world. Climate Consultant translates this raw climate data into dozens of meaningful graphic displays.

WUFI Passive - notes on every input for building a PHIUS+ 2015 or PHIUS+ 2018 energy model

An 11-page Word doc meant to help a novice to intermediate user identify and describe every input field and option in the WUFI Passive energy modeling software.

This is meant as an item-by-item inventory of every input required in WUFI Passive. I've added notes to help a new user understand the information that WUFI Passive and PHIUS require. This is very much a beta-quality resource -- there are probably a few entries that could use further clarification, if not outright correction, so please let me know how to improve it.
