LEED Platinum Certified Horticulture Center

LEED® Platinum Certified Horticulture Center

Conserving natural resources to build a sustainable future.

This 20,840-square foot facility provides work space for the Arboretum’s horticulture, public programs, and facility staff. The new space provides the infrastructure needed to match the tremendous growth the Arboretum has experienced over the past 30 years and to address future expansion of the institution. The “green” elements of the Horticulture Center serve an even greater function, through providing unique opportunities to educate the public about the importance of protecting our natural resources.

The Horticulture Center is not open to the general public to visit without a class, tour, or event scheduled in advance. The general public is welcome and encouraged to schedule a prearranged visit to see the eco-friendly structure.

LEED® Certification

The Horticulture Center was designed in accordance with the Leadership in Energy and Environmental Design (LEED®) Green Building Rating System, which provides a standardized approach to environmentally sustainable construction. The Arboretum is committed to “raising the bar” for itself as well as for the wider community; as such, it has achieved the highest level of LEED® Certification, Platinum, for the Horticulture Center project.

Sustainability Overview

The following features of the Horticulture Center demonstrate Morris Arboretum’s dedication to environmental stewardship, through reducing the Arboretum’s carbon footprint, engaging in sustainability best practices and qualifying for the LEED® Platinum Certification.

Geothermal Wells: An efficient ground-source heat pump provides heating and air conditioning for the building, using only about 1/4 the energy of a typical boiler/air conditioning system.

Green Roof: Green roofs on the garages will help moderate the temperature of the building, capture and store storm water, reduce carbon dioxide and provide beautiful view for staff and visitors.

Solar Energy: Photovoltaic panels will provide on-site generation of renewable energy, with peak electricity production during the hot summer months when the demand for electrical power is highest.

Air Quality: The building will be well insulated to eliminate infiltration of outside air and reduce the energy lost through the walls.

Lighting: The building’s lighting system is designed to take full advantage of natural daylight and minimize energy use by using skylights and roof monitors to supplement artificial lighting.

Water Cisterns: To reduce water usage, rain runoff from the building will be collected in cisterns for use in irrigation and in lavatories.

Recycling Construction Material: 40% of the building materials used in construction was regionally sourced, recycled or salvaged.
