16 Results - HOSPITALS We are proud to have introduced and obtained financial support for realization of the HOSPITALS project Attractive solutions have been demonstrated in 5 widely different types of hospitals All the hospitals have or will have a healthy indoor climate Considerable energy savings (~1/3) are obtained Quote from a nurse at Aabenraa Hospital: The new attractive glass covered courtyards means that patients are getting faster out of their beds and are able to walk around compared to the before the renovation ~ Expected savings of more than 500 euro per day per patient!

27 OCM Verona Verona, Italy Innovative elements Installation of a new efficient gas-fired central heating system Installation of efficient heat recovery for all the major ventilation units Integration of a very advanced building management system (BMS) for heating, cooling and ventilation Highly efficient cooling system Highly insulated building envelope (external wall) Multilayer glass façade system Energy efficient windows with integrated solar shading 27 /X

28 OCM Verona Energy Demand Overall performance of building envelope Insulated wall with a U-value of 0.28 W/m 2 K Multilayer window system with a total U-value of 1.2 W/m 2 K. The hospital will therefore be a highly insulated building that goes beyond future standards in Italy. Compared to standard design, savings of MWh or approximately m 3 gas. (~50%) are expected 28 /X
