Above Before renovation Right After renovation: The building’s eight original steel columns and trusses were determined to be structurally sound and now support the interior floors that were added during the renovation. The building required new HVAC, plumbing and electrical infrastructures. rainwater recollection translated to an estimated 33% reduction in water use as compared to a standard building’s estimated water use. Engineers not associated with the original design conducted fundamental commissioning to ensure systems started up and worked appropriately. Cannon Design engineers have ongoing access to the direct digital control system on their computers to monitor the function and performance of the HVAC systems. When looking at a graphical representation of the first year’s energy use, there is a noticeable spike during the initial move-in and occupancy period. This was due in part to the move-in and building flush-out processes. The building flush-out involved overventilating the building with 100% outside air that, at a minimum, kept the interior below 60% relative humidity and above 50°F during the entire process, even during unoccupied periods. By rapidly changing the air inside the building with outdside air, the contaminants introduced into the air during construction and movein activities are removed, creating 46 HigH Performing History of tHe Power House despite the grand success of the st. louis World’s fair in 1904, by the early 1920s st. louis’s population began to decline. in 1923 an $87 million bond issue was passed, a milestone of civic progress for the city. As part of the bond, the municipal services Building, designed by local partnership study and farrar, became part of the plan to breathe new life into downtown. The Power House, as it came to be known, provided coal-fired steam heat to a dozen downtown city buildings, including the civil and municipal courts, Kiel opera and City Hall. The Power House is listed on the national register of Historic Places as locally significant for community planning and development. engineering news record once wrote of the project, “This is the largest, most varied and best planned program of municipal improvements ever attempted by an American city.” The Power House remained an important building in the city until 1980 when it closed. it remained vacant for more than 25 years and became best known for the trees growing on its roof. Cannon design purchased the building for its new offices, realizing it would require significant and rigorous design analysis to get the building back into shape while preserving its history. The building was in serious decay, but its exterior shell and original structure steel were fundamentally sound. The Power House’s landmark revival style exterior has been fully restored and every component of the building’s interior is new and designed to current life-safety codes. The project achieved leed gold certification. Buildings summer 2011 © gayle Babcock
