<pre>Dear colleagues:<br><br> <br><br>It might be a complete 'faux pas' to send a design sequence based on<br>rules of thumb to a building simulation mailing list. But, I take the<br>risk. We recently developed and validated a rules-of-thumb based design<br>sequence for diffuse daylighting:<br><a href="http://www.gsd.harvard.edu/people/faculty/reinhart/documents/DiffuseDayl">http://www.gsd.harvard.edu/people/faculty/reinhart/documents/DiffuseDayl</a><br>ightingDesignSequenceTutorial.pdf. The series offers design advice for<br>daylighting at the programming and massing stage and - being based on<br>the daylight factor - applies to climates with either mostly diffuse<br>sky conditions or heavily obstructed sites. Alternatively, the design<br>sequence can be used in combination with a direct shading study. The<br>supporting research can be found at<br><a
