The building is fitted with mechanical ventilation, supplemented by openable windows. The original mechanical installation of the building was replaced by an air to air HVAC system equipped with heat recovery. The number of people visiting the Museum at any one time is variable and seasonally dependent. For this reason, the ventilation system includes demand control that allows fresh air to be supplied to the occupied zones only when the carbon dioxide concentration reaches a preset level.

Technical information on solar air conditioning with several case studies from several European countries. The demand for air-conditioning has been increasing through the last decade due to improved comfort and occurring higher temperatures. And with the higher demand come several problems: the extensive use of electrically driven cooling is leading to capacity straining power demand peaks in the summer and increase of green house emissions – either through leakage of cooling fluids or use of non-sustainable energy.

The main changes are: new buildings: the maximum allowed annual primary energy demand will be decreased by 30 % in average. The thermal requirements to the building envelope will be tightened by 15 % in average. existing buildings: in major renovations the thermal requirements for building envelope components are tightened by 30 % in average (facade, windows, roof). Alternatively the primary energy demand and the average transmission loss coefficient after the major renovation may not exceed the factor 1.4 compared to the requirements for new buildings.
