This month's RS Means Cost Comparison Chart focuses on office building construction.

(FER) studio, Inglewood, Calif., converted a 115-year-old former dry goods store in Louisville, Ky., into a 10,175-sf mixed-use commercial building earned LEED Platinum and holds the distinction of being the state’s first adaptive reuse project to earn any LEED rating. The facility, located in the East Market District, houses a gallery, event space, offices, conference space, and a restaurant. Sustainable elements that helped the building reach its top LEED rating include xeriscaping, a green roof, rainwater collection and reuse, 12 geothermal wells, 81 solar panels, a 1,100-gallon ice storage system (off-grid energy efficiency is 68%) and the reuse and recycling of construction materials. Local firm Peters Construction served as GC.

Chicago-based Goettsch Partners was commissioned by developer Guangzhou R&F Properties Co. Ltd. to design a new 294,570-sm mixed-use tower in Tianjin, China. The Tianjin R&F Guangdong Tower will be located within the city’s newly planned business district, and at 439 meters it will be one of China’s tallest buildings. The massive complex will feature 134,900 sm of Class A office space, a 400-key, five-star hotel, 55 condominiums, and 8,550 sm of retail space. The architects are designing the tower with multi-story atriums and a high-performance curtain wall to bring daylight deep into the building, thereby creating deeper lease spans. The project is currently finishing design.

Clif Bar & Co.’s new 115,000-sf headquarters in Emeryville, Calif., is one of the first buildings in the state to meet the 2008 California Building Energy Efficiency Standards. The structure has the largest smart solar array in North America, which will provide nearly all of its electrical energy needs.

The Shoppes at McHenry Row, a $117 million mixed-use complex developed by 28 Walker Associates for downtown Baltimore, will include 65,000 sf of office space, 250 apartments, and two parking garages. The 48,000 sf of main street retail space currently is 65% occupied, with space for small shops and a restaurant remaining.

Mixed-use development has been one of the few bright spots in real estate in the last few years. Successful mixed-use projects are almost always located in dense urban or suburban areas, usually close to public transportation. It’s a sign of the times that the residential component tends to be rental rather than for-sale.

One of the most famous office buildings in the world—and the official the residence of the President of the United States—is now worth only $251.6 million. At the top of the housing boom, the 132-room complex was valued at $331.5 million (still sounds like a bargain), according to Zillow, the online real estate marketplace. That reflects a decline in property value of about 24%.
