+======Checklist for Design: Ventilation System in a residential Passive House Building======
-\\
-With the help of this checklist you can easily check whether everything around the ventilation system has been installed correctly.\\
-  *Ventilation system:
+This checklist for the design of a ventilation system in a residential Passive House building has been written to aid building designers. It was compiled with the greatest care and to the best of the author’s knowledge. However, no liability for the accuracy and completeness of the contents, data and in particular for any damage or consequences arising from the use of the information presented here is therefore excluded.
-  * Controllability: At least 3 operation modes (‘boost’ +30%, standard, basic -30%)?
-    *Are all rooms ventilated, either by means of SUP, ETA or transfer air (also utility rooms, mechanical room itself etc.)?
-    *Excessively low relative indoor air humidity (< 30%)? Countermeasures taken?
-    *Sound level?
-    *Draughts?
-  *Ventilation unit:
-    *Accessibility for maintenance checked?: Filters, condensate pan and drain, heat exchanger, summer bypass
-    *Structure-borne sound decoupling of the ventilation unit?
-    *Are silencers planned for SUP and ETA, possibly ODA and EHA?
-    *Condensate drain with double siphon connected to drain pipe (check slope and filling level of siphons)?
-    *Is frost protection temperature for pre-heating set to the point considered in the energy balance calculation (PHPP)?
-    *If subject to frost (outside installation): Condensate drain heated and insulated?
-    *Intermitted operation: Filter drying before switching off fans possible?
-  *Filters:
-    *ODA filter (at least F7): correctly mounted (check fit and air flow direction)?
-    *ETA filter (at least G4): correctly mounted (check fit and air flow direction)?
-    *Do “pre-filter” and “grease filter“(kitchen) correctly fit in ETA?
-    *Accessibility and maintainability of the filters possible?
-  *Outdoor air (ODA) and Exhaust air (EHA):
-    *ODA intake: Clean air (at least 3 m above ground, air pollution, odour sources)?; Protected from manipulation, rain, snow?
-    *Avoid „short-circuiting“ between EHA and ODA (odours, direction of flow, distance)
-    *Don’t direct EHA outlets at building assemblies (risk of condensation).
-    *Outside wall penetrations: vapour tight? Thermally insulated? Connected to the airtight layer?
-    *Unit within thermal envelope: ODA and EHA ducts insulated up to the insulation layer of the thermal envelope with at least 50 mm, thermal bridge free and vapour tight? Short duct length?
-    *Unit outside thermal envelope: SUP and ETA ducts insulated up to the thermal envelope with at least 50 mm and thermal bridge free? Short duct length?
-    *ODA and EHA valves accessible for cleaning and inspection?
-    *Intermitted operation: Airtight ODA and EHA valves installed?
-    *ODA and EHA air volume flow calibrated and imbalance lower than 10%? Information to be filled in the commissioning report.
-  *Supply air (SUP) and extract (ETA) air ducts:
-    *Structure-borne sound decoupling of the ventilation ducts?
-    *Are supply air heating ducts sufficiently insulated?
-    *Are supply air cooling ducts sufficiently insulated and vapour tight?
-    *Do the ventilation ducts have a smooth interior surface?
-    *Duct system with minimal pressure loss? Duct crossing avoided?
-    *Are SUP and ETA ducts equipped with cross-talk silencers?
-  *Supply (SUP), extract (ETA) and transfer air valves:
-    *SUP and ETA air volume flows are adjusted as planned for each room? Information to be filled in the commissioning report.
-    *Are the SUP and ETA valves and their adjustment documented? Information to be filled in the commissioning report.
-    *Jet nozzles mounted approx. 15 cm below ceiling (from the middle of the jet)?
-    *Are the openings for air transfer planned in all designated rooms (e.g. 1.5 cm door gap) (pressure loss of max. 1 Pa, check by measuring the air flow velocity (< 1m/s))?
-  *Additional components:
-    *Kitchen hood planned with recirculation air?
-    *Kitchen hood planned with exhaust to outside? Additional supply air flow available? Not recommended for Passive Houses!
-    *Safety equipment checked for combined operation with a wood stove (if applicable)?
-    *Supply air heating coil tested (max. supply air temperature 52 °C, avoid dust smouldering).
-    *Room temperature adjustable independently from SUP air flow rate?
-  *Fire protection:
-    *Fire and smoke safety dampers clean and operation checked?
-  *Inspection of the subsoil heat exchanger:
-    *Check ductwork for leaks (pressure test).
-    *Check duct system for sloping (no unwanted basins)?
-    *Drainage (condensate) by means of a double siphon.
-    *Ensure accessibility (cleaning).
