The Green Building in Louisville, Kentucky, was home to a dry-goods store for decades starting in the 1890s. In its adaptive reuse, the building is now designed to outperform Kentucky energy codes by up to 65 percent. A semi-enclosed outdoor courtyard is partially shaded by a canopy of 81 solar panels. The masonry shell was sealed with inert recycled insulating materials. The original window openings, that had been filled in with cinderblocks, were restored with low-e insulated glass. Other sustainable design features include a geothermal heating and cooling system; an 1,100-gallon (4,200-liter) ice storage cooling system; an energy-recovery unit; a vegetated roof; rainwater collection for irrigation; daylighting and views in 95 percent of regularly inhabited spaces; exterior louvers on the south side for sun mitigation; control systems that meter HVAC systems, water usage, and energy performance; use of recycled-content materials; reuse of bricks; and reuse of existing old-growth wood members for framing, flooring, and furniture. Located in the city's distressed East Market district, The Green Building has helped revitalize the area with a gallery, event space, offices, conference room, and cafe
