Vasakronan, LEED EB:OM Volume



Thornton Tomasetti provided LEED EB:OM Volume consulting services for 48 mixed-use commercial projects acquired by Vasakronan, the largest property holding company in Sweden. Properties include Klara Zenit, a mixed-use office block with more than 70,000 square meters of offices, commercial spaces, a hotel and an entire residential neighborhood on its rooftop.

The sustainability team facilitated the initial sustainable design charette to align the project team towards supporting the development of a sustainable facilities program and accomplishing the ambitious goal of certifying 50 percent of the company’s real estate under the LEED EB:OM rating system in one year. Services included policy development, EB:OM prototype development, workshops, reviews, strategies, analysis and serving as a liaison between Vasakronan and the Green Building Certification Institute (GBCI).

Approximately 90 percent of the projects have earned LEED Gold and an EPA energy star score of 90 to100 possible points, placing them in the ranks of the highest performing buildings in the United States. The team has been able to leverage the EB:OM Volume program to significantly reduce energy and water consumption, saving as much as 30 percent of potable water consumption across Vasakronan’s portfolio of buildings .
