Michael Wall Engineering produced electrical construction documents for this 150,000SF tenant improvement. The work consisted of 100,000SF of high bay lab/testing/R&D space, a 25,000SF area of office improvements on the first floor, and a 25,000SF area on the mezzanine of office improvements. To help control illumination levels and costs, the office spaces have been designed to have recessed/direct/indirect lighting fixtures with electronic step dimming ballasts and motion control sensors. The overall lighting power density averages .807 watts per square foot, which is 27.8% better than allowed under Title 24. The high-bay industrial space is fitted with specialty fixtures housing T5HO lamps and LCP Controls, with watts per square foot at 20.7 % below Title 24. This project qualified for $96,311 in Sempra Utilities owner incentives and $32,086 in design team incentives, for a total of $128,397 in energy efficiency incentives. The total annual power usage savings are estimated to be $19,046, based on 150,047 annual kWh saved per year.
