When we save money...Our tenants save money!

Our HVAC system is quite revolutionary. The climate control system consists of a GeoExchange system that uses treated effluent from the nearby municipal sewage treatment plant as the heat source and sink. Two plate frame heat exchangers interface the effluent with the building loop. Pumping energy is minimized through the use of variable speed drives on both the effluent pumps and building pumps. Variable speed operation reduces the annual effluent pump energy by 90% and the annual building pump energy by 57%. Comparison of the GeoExchange system to a similarly sized water loop heat pump system with a boiler and cooling tower results in annual operating cost savings of 98% over the water loop heat pump system. This system results in an overall energy cost savings of 75% compared to the national average of office space heating and cooling.
