The 25-year-old Miami high-rise had a history of operational excellence, consistently reaching ENERGY STAR goals; the building was one of the few in ASHRAE Zone 1 with insulated glass and the water-cooled chilled water system already contributed to significant energy savings. Goals for enhancing the building and becoming LEED certified included reduced operating costs, improved marketability and a desirable indoor environmental quality for tenants.
The roadmap to achieving the initial LEED EB: O&M certification began with TLC conducting an analysis of LEED EB: O&M prerequisites and performing field investigations. Once basic LEED EB: O&M certification was achieved, the goal of LEED Gold recertification was pursued, moving the building towards greater levels of sustainability. Sustainable design features resulted in annual savings of $75,000 from upgrading the chiller plant and a 37% water-use savings, yielding an ENERGY STAR rating of 83 for the building.
