Case Study Floating Homes Vent-Axia provides MVHR system for an innovative Floating Home prototype Lo-Carbon Sentinel Kinetic BH With a housing shortage in the UK and an increase in building on flood plains, or land at risk of flooding, the Floating Home offers an exciting house building solution. Inspired by canal living and designed by Baca Architects, the ‘Chichester’ prototype model was built by Floating Homes Limited and is not a houseboat but a house that floats. Situated on a residential mooring on a disused canal which runs alongside Chichester Marina in West Sussex, the Floating...

Approved Documents F (ADF) and L (ADL) of the Building Regulations Approved Documents F (ADF) and L (ADL) of the Building Regulations were issued in October 2010. ADL was further revised in 2013. They place much greater emphasis on effective design, installation and operation of ventilation systems. The objective is to maximise carbon reduction through correctly specified and designed systems, competent installation minimising losses of the systems, verified performance once installed and correct operation by the home owner. What does this mean for ventilation? Ventilation uses energy in...

ADF Airflows, Background Ventilators and Noise There are some considerations dependant on which ventilation system is being used. These are outlined here but are shown in more detail in the separate sections for each system. Intermittent Fans and Passive Stack (System 1 and 2) These have different levels of background vents dependant on the infiltration rate of the building. MEV (System 3) Window vents are not needed in leakier buildings. MVHR (System 4) The rate of ventilation can be reduced dependant on the leakage of the building. If the building is leakier than 5m3h/m2 then the...

System 1 - Intermittent Fans and Background Ventilators Intermittent extract fan airflow rate based on table 5.1a from the previous page. The design air permeability will determine the equivalent ventilator area as laid out in the tables. System 2 - Passive Stack Ventilation (PSV) This system relies on the natural stack effect by which warm air rises and is extracted from the wet rooms through 125mm rigid ducts running to ridge height. Trickle vents are required and can be humidity controlled. Internal rooms require 'assisted' ventilation i.e. by mechanical ventilation. Background...

There are two ways to comply with system 3: Centralised (MEV) or Decentralised (dMEV). MEV incorporates a single unit that extracts stale air to atmosphere from all the wet rooms via ducting. Decentralised MEV requires continuous running extract fans mounted in all wet rooms in much the same way as a traditional fan is mounted. As shown on page 7, rates as per table 5.1a for the continuous systems are much lower than intermittent ventilation, and in kitchens particularly the rate falls from 60l/s to 13l/s. This can remove the requirement for noisy fans or cooker hoods completely. Reduced...

MVHR is a whole dwelling ventilation system that supplies and extracts air continuously at a low rate (as per table 5.1b) with the facility to be boosted as required. The unit is normally installed in the loft space or cupboard and rigid ducting supplies fresh filtered air to the habitable rooms and extracts stale polluted air from the 'wet' rooms. Supply and extract diffusers are fitted to the ceilings and are adjusted to balance the system. The unit incorporates a polymer heat exchanger that tempers the incoming air before it is delivered to the habitable rooms. The Domestic Building...
