Cooperative building societies are getting requirements from the European Union which they have to meet in a few years (Action Plan for Energy Efficiency: Realising the Potential). The target is to reduce the current energy consumption (heating and electricity) of buildings with 20% in 2020.The hypothesis is that with the correctly selected type of heat pump, with or without the combination with a CHP in the right proportions, a heating unit configuration exists with which mid to high temperature heating can be achieved in existing apartment buildings in the Netherlands, in a sustainable and cost effective way. Three heat pumps types were highlighted and explained, the Vapor Compression Heat Pump (VCHP), the Gas Absorption Heat Pump (GAHP) and the Compression Absorption Heat Pump (CAHP). Based on the yearly average temperature and the required temperature gain for the central heating water, the CAHP was the most economical option according to data from literature. The CAHP was investigated in more detail. When the heat pump was only able to deliver 336 kWth, the best investment and annual savings relation was obtained. With this configuration the heat pump is able to fully cover the 30-50ºC temperature range only. At higher required temperature ranges the heat pump would only deliver a part (336 kWth) of the total heating demand, up to 400 kWth would be delivered by a CHP and the remaining heating demand would be provided by conventional boilers. Despite that the Net Present Value (NPV) for the CAHP is 13% higher than the NPV for VCHP configuration, the latter is preferred. Since the CAHP is a rather new technology entering the market, more research is required in order to decrease the involved risk and uncertainties of the system.
