Each glasshouse environment is individually climate-controlled to provide humidified air, fogging systems, and automated ventilation sash operation with a shading system to control light and heat gain. A small addition on the south side will house the mechanical, electrical, and plumbing systems. In style it recreates the material and scale of the front elevation, respecting Independence Avenue and the overall Capitol Hill master plan. The main portion of the addition is below grade, and all of the building services, including piping and ductwork, run underground to the glasshouses to maximize planting area. Because Washington has such a high water table, soils engineering and extensive waterproofing were needed to keep the basement addition dry.
