High energy savings can be expected from building energy and climate concepts which combinethe heat pump technology with a low temperature energy distributions such as concrete corewater pipe circuits within building zones. The paper describes two case studies of a heat pumpplant for heating and cooling of nonresidential buildings. For concept comparison purposes aglobal objective function will be developed in the frame of IEA-ECBCS Annex 48 and has beenpartially tested by using project constrains, thermal comfort expectations and lifecycle costs of thefoccused case studies.
