Designing High Performance Sustainable Buildings

Objectives are: 1. To show you how to use HEED to design a Basic Residential Building 2. To show you how HEED reports Site Energy Use and CO2 Production with each design change you make. 3. To show you six concepts of Energy Efficient Buildings using HEED’s Advanced Graphic Evaluation tools 4. To give EACH of you a chance to use HEED on your own. 5. To end by showing how well each of your designs compare. Read More

US Historic Declination (1750-2010)

This programs derives a table of secular change in magnetic declination for a specified point in the conterminous United States. It utilizes the USD polynomial & the IGRF spherical harmonic models. Declination is shown to the nearest minute so that secular change may be properly illustrated, but it is usually only accurate to within 30 minutes. Read More

Sun Path Chart Program

This program creates sun path charts in Cartesian coordinates for: (1) “typical” dates of each month (i.e.; days receiving about the mean amount of solar radiation for a day in the given month); (2) dates spaced about 30 days apart, from one solstice to the next; or (3) a single date you specify. You can select whether hours are plotted using local standard time or solar time. In addition, there are a number of options available to allow you to alter the chart’s appearance. Read More

Wind-to-Hydrogen Project

Snapshot of wind-to-hydrogen video with photo of wind turbine and graphic of a white electrolyzer (with text that reads ‘Emissions-Free Electrolyzers’) and a green hydrogen-powered generator (with text that reads ‘Green Electricity Generation’). View the Wind2H2 video. The National Renewable Energy Laboratory (NREL), in partnership with the Xcel Energy, launched a wind-to-hydrogen (Wind2H2) demonstration project at the National Wind Technology Center in Golden, Colorado. The Wind2H2 project links wind turbines to electrolyzers, which pass the wind-generated electricity through water to split the liquid into hydrogen and oxygen. The hydrogen can then be stored and used later to generate electricity from an internal combustion engine or a fuel cell. The goal of the project is to improve the system efficiency of producing hydrogen from renewable resources in quantities large enough, and at costs low enough, to compete with traditional energy sources such as coal, oil, and natural gas.
