Zero heating building

This means heating in highly urbanized areas is directly or indirectly powered by, in a large part from fossil sources.

About 2000 TWh of seasonal energy storage is needed to meet EU's winter heating demand,[3] should it be alleviated from fossil fuel dependency.

[5] Zero-heating buildings are built in the similar way as Passive houses while taking advantage in the recent developments in ultra-low U-value glazing.

[8] A zero-heating building is proposed as a cornerstone of a market acceptable solution to the problem of the CO2 mitigation through reduction of the need for seasonal energy storage.

Abandoning now common modulated external shades and switching to more cost-efficient multipane glazing with built-in solar control glass somewhat increases cooling demand.

Quadruple glazing, as the main add-on component to the passive house, cost is essentially that of triple-glazing plus one more intermediate glass pane at about €10 /m2.

As quadruple units allow for U-value of glazing to be less than 0.4 W/(m2K), external modulated sun shading, and its substantial cost can be omitted without any loss of energy performance.

Limited or no contact with the environment and living and working with minimal daylight are often a consequence of dynamic sun shading.
