Water Conservation & Critical Plant Selections During cold months, the shading system also acts as a thermal blanket, operating during evening hours to trap heat inside and reduce radiative heat loss. Additionally, an automated shading system is deployed to reduce solar heat gain during the hottest days of the summer. Outside air entering through these vertical openings flushes out heat buildup, with hotter air rising and escaping through the roof openings, which comprise 15-20% of the overhead surface area. Based on historic precedent and refined via advanced thermal conditioning modeling, the West Conservatory incorporates 10-foot-tall operable vertical façade openings along the building’s entire perimeter. This innovative design means the building uses only natural ventilation, rather than relying on mechanical cooling, during warm months. ![]() ![]() The tempered air is introduced at the pedestrian pathway to provide passive thermal comfort for occupants. Ten earth ducts-three feet in diameter, 250 feet long, and buried outside the conservatory-provide year-round passive tempering of fresh air in the conservatory. The West Conservatory employs a unique combination of passive and tempering strategies. “Inspired by Pierre du Pont’s spirit of innovation, we have designed a living and breathing glass house, with walls and roofs that open and close in response to the weather, earth tubes that draw temperate air inside, and roof valleys that collect water, creating a sustainable destination we hope will become an enduring source of wonder and inspiration,” said principal architects Marion Weiss and Michael Manfredi. The Mediterranean Garden designed by Reed Hilderbrand is adaptable to climate variations, and is especially noteworthy for its optimization of water usage in the oases of fountains, pools and plantings, that are being created.” Redman adds, “WEISS/MANFREDI has designed a building that not only is at the forefront of glass architecture, but leads the way in sustainability. Since then, the conservatory complex has continued to grow and evolve with each generation adding state-of-the-art structures that incorporate new, innovative horticultural displays within.” Rendering of an interior view of the West Conservatory. du Pont opened one of the world’s great greenhouse structures, designed by J. Redman, president and CEO of Longwood Gardens. “The West Conservatory and the new Mediterranean Garden are capstones of 100 years of innovation in greenhouse and garden design at Longwood,” says Paul B. The glasshouse now has a fully constructed steel frame and is in the process of having nearly 2,000 glass panels installed, bringing the sweeping, deeply sensitive transformation nearer completion. The centerpiece and largest single element of Longwood Reimagined is a 32,000-square-foot glasshouse designed for sustainabiity by WEISS/MANFREDI, with gardens, pools, and fountains designed by Reed Hilderbrand. Longwood Gardens, a botanical garden in Kennett Square, PA, recently reached a major milestone in its 17-acre transformation of the core area of conservatory gardens.
