Inquiry

The August Wilson Center for African Culture (AWC) is a new construction, performing arts facility located near the wide end of the Golden Triangle of downtown Pittsburgh. We are operating under LEED 2.1 for the project. Our building is situated on the property line for two (2) of its sides. In the case of the one of the two sides, our building faces a controlled alleyway, which is bordered by another building on the long axis, and gated on the two entries to the alley (gated card access controlled by our building). There are currently no lights mounted to the existing building, and since our building will now enclose this walkway, we have taken it on ourselves (both for emergency code reasons as well as safety reasons) to light this alley. Obviously we are lighting over our property line, but it is in a controlled, and energy efficient manner. Our fixture selection utilizes full cutoff CFL fixtures (26W) spaced 18ft OC. Optically these fixtures have a short forward throw (as the alley is only 8ft or 16ft wide, depending on location), and a wide lateral throw. Illumination values are an even, with a moderate maximum value of 5.5fc, and a minimum value of just over 0.6fc. The notion is that there is no way to light this space according to the letter of LEED. However, as it needs to be lit, we are following the principles that otherwise govern good LEED practice. Please advise.
