TruexCullins Architecture and Interior Design is pleased to announce that the Heritage Aviation facility at the Burlington International Airport has achieved LEED® Gold Certification from the United States Green Building Council (USGBC). This major renovation and building addition project for Heritage Aviation started with the complete reconstruction of a vacated 1954 hangar. The original structure was formerly occupied by the Vermont National Guard and has since been repurposed and transformed into a state-of-the-art aviation services facility totaling 75,800 sq.ft. Aviation is an energy-intensive industry, accounting for 3% of global carbon emissions. The Heritage Aviation facility has taken extraordinary measures to counteract this impact and promote a sustainable model for the industry. Some of the most notable environmental accomplishments of the building include these features: * Through the use of multiple on-site renewable energy sources, Heritage Aviation is generating 15% of their energy needs, saving 200 kW Hours per 10-hour daytime shift every day. The majority of this energy is produced by a 100 Kilowatt commercial wind turbine mounted at the southeast corner of the parking lot. This FAA-approved wind turbine was the first community-scaled wind turbine installed at a regional airport in the United States.* An additional 3.4% of the project’s energy needs are met with a roof-mounted, 10-panel 65.2 MBtu solar thermal domestic hot water system and an adjacent 120-panel 25.2 kW solar photovoltaic array.* The building features a 13,742 sq.ft. “green” roof, with several varieties of sedum planted in a waving pattern as seen from the air. The vegetated roof retains the first 1″ of rainfall that falls on it, with the excess directed toward underground irrigation tanks. When installed, this was the largest green roof in New England, and remains the largest in Vermont.* The south parking lot features a porous concrete surface that is designed to absorb all rainfall based on a 100 year storm, eliminating the erosion and polluting affects typically caused by excess stormwater runoff. At 87,117 sq. ft., this is the largest pervious parking lot in Vermont, and one of the largest in New England. A building energy model was used to compute the projected energy savings from the efficiency improvements to the building shell, the mechanical and electrical loads, and the power generated by on-site renewable energy sources. According to this model, the Heritage Aviation facility is realizing a 38% energy savings over a standard commercial building of the same size. Actual data from the first year of operation indicates even better energy performance. The facility has now been in operation since January 2010, and during this time, the building has seen a savings in gas and electricity consumption of 54% over a conventional office/warehouse building.
