Completed work on Boland Building

Renovation of office space in an existing two story office building built in the 1950's.  This project was certified under the LEED Core and Shell rating system.  Requirements of this certification include earning a minimum of 2 points under EAc1 energy efficiency.  Improvements to the building include replacing single pane glass on the north elevation and replacing old rooftop and split system air conditioners with new, high efficiency systems.  The baseline building showed a 14.5% energy cost savings over the baseline case.  This project also renovated all bathroom fixtures with new low consumption fixtures.

Frey Building Mechanical Renovations Completed

Eleven story office building that was origionally built in the early 1970's.  Mechanical systems for renovation include the replacement of the existing steam absorbtion chillers, renovation of the chilled water and condensor water systems to include variable speed pumping and enthalpy based cooling tower fan control as well as new DDC air handling system controls for the main air house which serve the majority of the building.  In addition the District Steam system was removed for heating purposes and new high efficiency modular gas-fired boilers, a gas-fires domestic water heater and gas-fired humidifiers were installed to meet the buildings heating, service water and humidification needs.  The HVAC improvements have been installed and are currently saving approximately $246,000 annually.
