    1 - climate data for PHPP - specifically for Wexford

    Whatever weather data comes with the PHPP (2007?) it is propably useless when calculating the real heating and cooling demand.

    The weather has changed, the old weather data statistics used in the PHPP where unreliable, propably always far off reality.

    So make sure your PH planner is not using useless data selling you a useless calculation!
    Use reliable data, not the data material coming with the old PHPP.

    How the official weather statistics have changed ( mainly due to the increase of solar radiation) learn at
    the official EU home page " PVGIS ".

    Here the link:

    and here the explanation why the new weather statistics show a huge difference in avarage weather patterns compared to the old and outdated statistics :
