The document discusses the Passive House energy design standard, which aims to achieve a 90% reduction in space heating needs and 70% reduction in total building energy usage. It provides examples of Passive House buildings constructed in Europe and discusses the key design principles, which include superinsulation, airtight construction, and heat recovery ventilation. Compact building designs that minimize surface area are emphasized to reduce energy demands. The Passive House Planning Package (PHPP) is used to calculate and optimize building designs to meet the rigorous Passive House criteria.
5. the ‘passive house’ energy design standard an energy efficiency design standard (and methodology) achieving 90% reductions in space heating energy, and 70% reduction in total building energy use.

24. Model B A two-story version of Model A… 1500 sq ft, Double-story 25’ x 30’ ( EA:TFA = 2.9 ) Exact same windows and doors as Model A.
25. Model C Rowhouse of Four 1500 sq ft, Double-story apartments, 100’ x 30’ ( EA:TFA = 2.2 ) Slightly less southern glazing (8.3% of floor area), no east/west windows or doors.
26. This 4-unit Row House is 27% more compact than a stand-alone unit would be, but has 85% less space heating energy use (given the same insulation and windows). This allows insulation levels (and construction costs) to be decreased while still meeting the Passive House Standard… In fact, at this scale, insulated window frames are no longer necessary, and non-south facing windows can be double-pane, low-e (but south-facing glass must still be triple-pane). Compactness Study…
43. simplified mechanical system Because windows are so efficient, there is no need to locate heating registers adjacent to them, thus duct runs are shortened.
