The Engineering and Science
(E.S.R.B.) was opened in 2004 as an addition to Barrows hall on the
University of Maine campus and has since made a huge impact in sensor
technology. As a result of the equipment in use for this
facility, OSHA requires that 65,000 cubic feet of ambient outside air
be brought into the building every minute. This is accomplished
using a series of blowers driven by 30 HP motors, the air is then
heated using energy created from the combustion of #6 oil at the steam
plant. The air that is exhausted from
building is at room temperature and blown straight outside.
is currently no means for saving heat from the room temperature air
exiting the building which leaves all of the heating requirements for
outside air directly on the steam plant.

This system will be extremely effective on cold days when it
take heat from outgoing room temperature air and deliver this heat to
the incoming outside air. The heat recovery system is

summer days, taking some load off the air conditioning system and
adding to overall savings produced from this small unit.
