This research explores building envelope thermal radiant cooling in commercial and residential properties.

This research examines the constant dependence of mechanical systems both in commercial and residential applications have become an ever increasing energy source which consumes the highest kilowatt use per month on average. Investigating additional uses for these mechanical systems, may lead in lowering monthly energy consumption while capitalizing on passive energy sources which are commonly discharged directly into the waste water systems. Condensate lines on HVAC system have always been the end result of the evaporation cycle, thus releasing clear water to nearby drains. 

Condensate recovery is not a new idea holistically, many HVAC systems capitalize on this water source by reintroducing condensate recovery into the HVAC systems again. However, if this resource is extended for building envelope thermal radiant cooling, it takes on a new meaning. The integration of condensate recovery and thermal radiant wall cooling loop has the opportunity to evolve into another level of sustainability which can effectively lower utility cost from 12 - 45%, while still achieving thermal comfort in the building.

Thermal radiant wall cooling is also not a new idea, these systems historically have found more use in Europe than in the United States. Yet, the integration of the two systems and other sustainable water collecting cisterns may be a new way to shed light to an old problem of reducing peak energy cost while maintaining thermal comfort for occupants regardless of climate zone and the control of condensation.
