Rohde Building retro-commissioning
Project Summary
Through a program targeted at reducing energy consumption in public buildings while maintaining a comfortable environment for building tenants and guests, the Florida Department of Management Services engaged Hanson to retro-commission the Rohde Building in downtown Miami.
The Rohde Building consists of two towers (north and south) with more than 337,000 gross square feet of office space. The south tower was constructed in 1976 and the north tower in 1986.
As a part of a multi-step, retro-commissioning process, Hanson conducted a facility site assessment visit, reviewed record documents, analyzed utility information and evaluated existing control strategies. Hanson's field investigation included interviews with operating personnel, observations of the buildings’ energy-consuming systems and identification of potential energy-conservation measures.
The retro-commissioning report included recommendations for specific energy efficiency improvements for the primary building energy systems (heating, ventilation and air conditioning equipment and distribution, lighting and associated controls), along with a preliminary financial analysis of the recommendations, which included estimated implementation costs, projected savings estimates and break-even return on investment.
A mix of low-cost measures and a couple of small capital improvements reflected savings of approximately $30,000 per year with a payback slightly less than two years.
