Editing Passive solar building design (section)

==Comparison to the Zero heating building ==
{{Main|Zero heating building}}

With advances in [[quadruple glazing|ultra low U-value]] glazing a Passive House-based (nearly) [[zero heating building]] is proposed to supersede the nearly-zero energy buildings in EU. The zero heating building reduces on the passive solar design and makes the building more opened to conventional architectural design.
The annual specific heat demand for the zero-heating house should not exceed 3 kWh/m<sup>2</sup>a. Zero heating building is simpler to design and to operate. For example: there is no need for modulated sun shading in zero-heating houses.
