Making the Case for Passive House Office Buildings

The Passive House Standard is largely known for drastically reducing a homes energy consumption, at the same time providing an extremely comfortable and healthy living space. But the standard is also applicable to other building types including schools, kindergardens, care facilities, wineries and all types of commercial buildings including office spaces. While the general benefits are basically the same, the planning  is quite different: For example, if it comes to office space (and larger buildings in general), projects in Europe and North Amercia have shown that meeting the stringent Passive House heating requirement is less of a challenge compared to residential buildings – more attention is paid to optimizing the energy consumption of the ventilation & cooling system and lighting. Also, over-insulation can make it more difficult to passively cool the building thus potentially increasing the cooling load. Careful planning and early building simulation is therefore crucial to avoid costly mistakes.

Passive House Office Buildings consume up to 85% less energy for heating and cooling and up to 65% less in overall building energy consumption compared to conventional construction. More importantly, working in a PH office building increases the occupants overall productivity, well-being and comfort – not to mention drastically reducing certain health concerns such as allergies, etc. All features the potential tenant(s) and investor(s) will appreciate. But how does a PH Office Building compare visually?
