The use of the same piping, typically manufactured of copper, synthetic rubber such as EPDM, and plastics such as polyethylene, polypropylene and polybutylene for the circulation of cold water is today still relatively unknown and faces certain resistance not only by clients but also the design munity. Radiant Cooling A corecooled ceiling is the cooling equivalent of a floor heating system. In the radiant cooling system, cold water is circulated through plastic piping. These pipes can be embedded into the slab either closer to the floor or at the ceiling level. If in bination with radiant, warm water piping, utilizing the same pipes, a location in the floor is preferable, since heat radiation from a ceiling surface to occupants in a room is undesirable. In both instances the presence of a thermal storage mass, such as the concrete floor slab, is necessary to house the piping. The pipes are distributed in a pattern of meandering tracks and need to be coordinated with the steel reinforcing in the concrete slab and possibly with electrical conduit and wiring. The underside of the concrete slabs is exposed to the floor space below and acts similar to the cold water circulating through the pipes as a heat sink for the warm air in the room, thereby replacing the air in the traditional forced air system. Taking advantage of the storage capacity o f the concrete provides the opportunity to shift the building peak load away from the utility grid peak. This translates into substantial energy savings in the building, as water is about three times more efficient than air as a heat transfer medium. In the case of the Brose building our current conservative estimate predicts energy savings of 10% over the traditional forced air system. Other radiant cooling systems place the cooled piping grid into a panel, which is suspended from the structural slab, thus eliminating the need for a concrete slab and the more laborious integration involved. Those panels are usually built from aluminum panels, with metal tubes connected to the rear of the panel. An alternative is to build a sandwich system, in which the water flow paths are included between two aluminum panels. It is important to point out the all panel systems are unable to take advantage of thermal mass due to the absence of embedded piping in a structural concrete slab, yet open opportunities for a more flexible solution of acoustical and electrical lighting requirements. Embedded capillary tubes, embedded in concrete slabs only takes fully advantage of thermal storage capabilities of the respective mass if these masses are exposed to surrounding thermal ambient air conditions. Cooling grids can also be imbedded in plaster, gypsum board, or mounted on ceiling panels. These systems provide an even surface temperature distribution. Due to the fact that plastic tubing for hydronic heating and cooling is flexible。 its placement has only to pay attention to structural conditions (. density and placement of reinforcement steel), namely near
