PASSIVE HOUSE CHECKLIST


1) Site Plan

* Proximity to public transportation.
* South orientation of the "main" side (± 30°), and large south-facing window areas.
* Freedom from unwanted shade from building elements, to allow passive solar energy use.
* Planting that will not cause unwanted shade in the future.
* Is a compact form possible? Row and multi-story buildings are advantageous.


2) Concept Development

* Use a compact building shell, and take advantage of opportunities to combine buildings.
* Glazed surfaces facing south are optimal; keep east, north and west windows small.
* Minimize shaded areas (very little or no shade in winter from railings, parapets, building projections, balconies, roof overhangs, divider walls, etc.)
* Use a simple shell form (if possible, without dormers, returns, etc.)
* Use a building footprint that concentrates utility installation zones (e.g., bathrooms above or adjacent to kitchens and each other).
* Leave room for ventilation ducts.
* Separate basement (if any), airtight and free of heat bridges.

* + Use the PHVP (passive house pre-planning package). Apply for passive house construction subsidies (e.g., from the "Kreditanstalt für Wiederaufbau"), if available.


3) Building Permit Plans

* Determine insulation thickness of building envelope.
* Avoid heat bridges.
* Determine size of utility room(s).
* House footprint: short pipe runs (hot and cold water, sewage) und ventilation ducts. Cold air ducts outside; warm air ducts inside the insulated building envelope.
