Friendship Manor in Lansing is a 170 unit, senior housing facility. The original building mechanical systems had not been updated for more than 20 years. The six heating and cooling systems consisted of 22 gas-fired absorption chillers with gas hydronic boilers, all distributed on the building roof and supplied 30 apartments each.  These were reduced to 3 systems supplying 60 apartments each, using a combination of Robur gas-fired absorption heat pumps and Robur chillers with heat recovery to bolster the domestic hot water system. A total of 110 tons of cooling. In addition, an Intellihot instantaneous 1,001 MBTU domestic hot water boiler replaced the aging boilers and storage tank that were in place.

We have worked with Performance Engineering Group going on 20 years now. Over the years, we have installed over 200 pieces of their equipment. They have been very easy to work with and have always given us great service. Mary Marble, Marble Mechanical Service, LLC
