December saw lots of changes at the ClearSense building on Rigsbee Ave in downtown Durham. We started the month with the new steel frame, roof, and floor slabs in addition to what remained of the exterior shell of the original single story building. We are very pleased with our choice of roofing panel. The R-42 insulated metal panel is both super insulated and aesthetically pleasing on both surfaces. The underside will be the finished ceiling to the second floor interior space. (see photo below)
By the holiday break (at our required pace for this project, none of our team took much time off), one interior stair was roughed in, plumbing, mechanical and electrical systems were at 50%, storefront window frames were installed, and some of the second story siding work was completed. Most prominently, the wind turbines and photovoltaic array are up! (see photo of the ClearSense rooftop below) These systems combine for a rating of approximately 35.5 kW to power the building of just under 12,000 square feet. The turbines are quite prominent, practically a beacon of clean energy generation. We're very proud of them - are they the first building mounted wind turbines in Durham, in the triangle, in the piedmont? Please let us know. Unless someone tells us otherwise, we'll take credit for that as another of many "firsts" in our local building industry (see our website “Recognitions” page for more).
Our goal is that the building itself will be constructed to be approximately 50% more energy efficient than a typical existing commercial building of the same size and use and that the clean energy generation will provide approximately 37% of the remaining power needs of the building. Though our team only designs and builds energy efficient and certified "green" buildings, we were able to exceed our regular standard and install the clean energy generation systems with the help of a grant proposal accepted by the North Carolina Green Business Fund. We are very pleased to have established this relationship and thankful to the NCGBF for their assistance. Stay tuned for more on the innovative work at 502 Rigsbee Avenue.
