To Whom It May Concern:
As a sustainability-oriented electrician certified as a solar PV installation professional by the North American Board of Certified Energy Practitioners (http://www.nabcep.org/), I am always alert to energy-saving opportunities in the buildings I visit. I am happy to report that the basement level counter service areas of the City’s Municipal Services Building, located just across from City Hall at 15th & JFK Boulevard, can save about $2,500 per year in electricity consumption — plus about 4/5 off on lamp replacement labor costs, and a continuous 8kW of cooling load, by swapping about 160 inefficient PAR type filament lamps for new LED types.
(Note that these filament PAR lamps will become increasingly difficult to source, following the January 1, 2013 cessation of production and distribution in the United States. Implementing a proactive replacement plan now will realize the maximum energy cost-savings while ensuring uniform lighting from identical lamp types, throughout the affected areas.)
The investment cost would be about $3200, so the payback is less than two years on this conservation retrofit — and this is before subsidies for lighting efficiency rebates available through PECO.
Although the numbers may be small in the scheme of a very large municipal energy bill, please consider the public information potential of this type of investment in the public face of the City’s municipal services. Also, you may have substantial additional opportunities in the building that could multiply the savings from a retrofit project by 10- or 100-fold.
