While anything based on daylight factors is limiting, you have qualified that every step of the way. The nice thing about this is that you have created a process for really applying a daylight factor approach early on in the design process. You should cross-post this to the radiance list!</div><div><br></div><div>Rob Guglielmetti </div><div><br></div><div><br></div><br><div><div>On Apr 9, 2009, at 7:02 AM, Reinhart, Christoph wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-align: auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0; "><div lang="EN-US" link="blue" vlink="purple"><div class="Section1"><div style="margin-top: 0in; margin-right: 0in; margin-left: 0in; margin-bottom: 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; "><span style="color: rgb(31, 73, 125); ">Dear colleagues:<o:p></o:p></span></div><div style="margin-top: 0in; margin-right: 0in; margin-left: 0in; margin-bottom: 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; "><span style="color: rgb(31, 73, 125); "><o:p> </o:p></span></div><div style="margin-top: 0in; margin-right: 0in; margin-left: 0in; margin-bottom: 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; "><span style="color: rgb(31, 73, 125); ">It might be a complete ‘faux pas’ to send a design sequence based on<span class="Apple-converted-space"> </span><i>rules of thumb</i><span class="Apple-converted-space"> </span>to a building<span class="Apple-converted-space"> </span><i>simulation</i>mailing list. But, I take the risk. We recently developed and validated a rules-of-thumb based design sequence for diffuse daylighting:<a href="http://www.gsd.harvard.edu/people/faculty/reinhart/documents/DiffuseDaylightingDesignSequenceTutorial.pdf" style="color: blue; text-decoration: underline; ">http://www.gsd.harvard.edu/people/faculty/reinhart/documents/DiffuseDaylightingDesignSequenceTutorial.pdf</a>. The series offers design advice for daylighting at the programming and massing stage and - being based on the daylight factor - applies to climates with either mostly diffuse sky conditions or heavily obstructed sites. Alternatively, the design sequence can be used in combination with a direct shading study.
