                           PBW2 – HVAC TEHNICAL
                                   DATA
   Heat pumps: 17 pcs. water-to-water and 12 water-to-air
   750 m2 of special surfaces of under-floor piping system for
    heating and cooling
   Ventilation channels - some visible, some hidden -
    connected to several water-to-air heat pumps, located
    mainly in the false ceilings of the building
   Ground source heat exchanger - 128 vertical boreholes of
    70 – 75 m depth each were installed on a 3.500 m2 field in
    order to ensure a total 475 MWh for heating (and hot
    water), and 393 MWh for cooling
   For the time period under survey, the coefficient of
    performance of the HVAC system was higher than
    COP=4,8.

                             PBW1 - PBW2 SURVEY
                            (WINTER SEASON 2006/2007)

   PBW1 is another Porsche facility for SKODA and VOLKSWAGEN
    cars with classic HVAC system and 5231 m2 (similar construction
    in very close area, with identic solar orientation, same functions,
    commissioned in January 2006).
   PBW1 use natural gas for heat and hot water, and last generation
    Air–to-Air VRV (Variable Refrigerant Volume) multisplit systems
    for ventilating and air conditioning during winter and summer.
   After commissioning of PBW2, ASA asked to Romanian
    Geoexchange Society – Mr. Radu Polizu – authorized auditor,
    member of ASHRAE to initiate a 12 months survey in PBW2. The
    existence of PBW1 and PBW2 allowed a simultaneous survey of
    the 2 systems.
   The survey was based on real consumptions (invoices) for natural
    gas (PBW1) and electric energy (PBW1 and PBW2).
   The presented results refers at the two systems during the cold
    season between October 2006 and April 2007.
   At the end of November Mr. Radu Polizu will publish the survey
    results for 12 months (October 2006 – September 2007).

                          SURVEY CONCLUSIONS
                           (WINTER SEASON 2006/2007)

   If properly designed, implemented and used, the
    GSHP HVAC system brings important economical and
    ecological advantages, compared to the classic HVAC
    solution
   The consumption of resources for heating, ventilation
    and hot water in winter season in a GSHP HVAC
    system is 5 times smaller than in a technically
    equivalent classic system
   The CO2 pollution in GSHP HVAC system is 10 times
    smaller than in classic system with natural gas
   The expenses for the cold season of the year in GSHP
    HVAC system are 3 times smaller than in classic
    system (the situation will become even more
    favorable for GSHP systems in the near future due to
    the predictable increase of the natural gas price)
