Commercial Real Estate

Commercial Real Estate

Commercial real estate properties represent nearly 15 billion square feet of floorspace. These properties consume more than 17% of all commercial building energy use and spend more than $30 billion annually on energy. Through the Better Buildings Alliance's commercial real estate sector group, 51 partners who own, lease, or manage over 6.6 billion square feet of commercial space, equivalent to 40% of the commercial real estate market floorspace, are sharing best practices, and engaging with technical experts to advance their energy savings goals.
