Longwood Gardens
A Sustainable Showcase for Botanical Beauty
In support of Longwood Gardens’ dynamic reimagination of its 17 acres of indoor and outdoor gardens, JB&B provided extensive MEP/FP and low-voltage services for its West Conservatory and the broader Longwood Gardens Reimagined project. The work began with a detailed indoor climate model that informed a highly integrated systems approach: earth tubes passively precondition ventilation air drawn through berms adjacent to the building; automated blinds manage solar heat gain and light levels across the glasshouse; operable openings allow natural ventilation whenever outdoor conditions permit; and a geothermal well field with water-to-water heat pumps provides all-electric heating and cooling to the project’s actively conditioned spaces.
Rainwater capture and reuse systems support the project’s broader sustainability strategy. Humidity, temperature, irrigation, root-zone heating, and lighting controls are coordinated within a single environmental framework tailored to the needs of the conservatory’s plantings and its visitors. The parking lot included eight Level 2 EV chargers and electrical infrastructure sized for future growth to 50% of parking spaces.
