Passive building

Passive construction is, that buildings are very well insulated, and consume less energy for space heating than 15 kWh/m² per year. This is achieved by making use of an insulation package with a high Rc value. Use This is a compact building method, a sophisticated orientation, applying proper operation of glas (triple), an excellent draft proofing, building thermal bridge. Can also be made ​​use ofPassief bouwensolar energy, and a ventilation system with heat recovery unit.The total energy consumption of a passive building is four times lower than a Dutch new building from 2011 and emits 54% less CO2. A building is not officially a passive as the national Passive House Foundation issued. Both a design certificate as a performance certificate If control and design tool above the PHPP calculation program developed. The PHPP (Passiefhuis Engineering Package) calculates the annual heat demand, primary energy consumption and cooling requirements/overheating frequency. After approval of the installation and instructions and the PHPP printout by the National Foundation gets the building design certificate assigned. To obtain the certificate does implement the National Foundation after the completion of the building-a BlowerDoor Test, which checks whether the luchtdichtheideis is removed. Also check the foundation or the realized building matches the input of the PHPP computer. If the building has obtained two certificates, it is officially a passive house. The substantial energy savings in the longer term to ensure a return on investment of the investments made. In passive construction is not only homes but also schools, offices, police stations, distribution centers, etc. For these buildings should be carefully looked at the availability of the existing thermal mass, and the requirements for fire safety.

Possible measures to achieve a passive house to come (especially source Pego Concept Line):

  • target is to walls without “leaking” the German Passivhaus Institut requires an air permeability 0,6 n50/h
  • extremely good air seal, with long life
  • use passive solar energy
  • Avoid excess temperature in summer (due to solar gain), eg . good high solar radiation
  • Rc’s (7-10 m2K / W) by a tight building envelope
  • insulation of windows and doors (U frame; 0,9 W/m2K)
  • insulating glazing (U glazing between 0,55 and 0,85 W/m2K)
  • no thermal bridges (many details as possible to improve, consider eg the letterbox)
  • balanced ventilation with HR recovery, DC fans and isolated channels
  • minimal installation space heating appliances (eg air heating via ventilation)
  • insulated hot water pipes
  • compact installation for space (zonnegascombi, compact heat od)
  • reduction of domestic energy (efficient appliances and lighting)

 

In a passive house is not required that there is even no external energy may be used such as in a zero energy house.
