-======Checklist: Ventilation System======
+======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.
-  * 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 (F7/F8): 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).
