MVHR CASE STUDY

A radial design with two central manifolds was chosen so that individual sound attenuators to each valve would not be necessary. The Q MVHR system is now up and running, with a total turnaround from Enhabit receiving the initial request from the client through to design, installation and commissioning of just eight weeks. With winter approaching the homeowners were having to keep their windows and doors open daily in an attempt to clear the air of VOCs, which was proving more and more uncomfortable as the temperature in London dropped. These potentially dangerous VOCs tended to become particularly concentrated in the study room and the third bedroom, which did not have any natural ventilation from windows or draughts. Twenty separate ducts measuring a total of metres were situated all around the houseboat in this way. High levels of VOCs can cause sickness and discomfort, and the effects of these VOCs was exacerbated by the incredibly-high airtightness level of the boat at 0.

A final word from the client: Enhabit has strict parameters on acoustics, pressure drops and energy performance when designing any MVHR system, as we want the MVHR system to run as quietly, as comfortably and as efficiently as possible for inhabitants. Enhabit was contacted last autumn by a couple living on one of the largest houseboats in London, moored permanently in a marina in East London. Making buildings better Products and support for energy efficient homes and buildings. This problem was exacerbated by the steel skin of the vessel being almost completely air tight: High Trees low energy newbuild project, Yorkshire. Award-winning energy efficient newbuild house, built into a steeply sloping Sheffield garden site.

This halved the amount of air coming out of each valve, reducing the risk of the air feeling draughty as it flowed into the rooms. These high flowrates, plus the difficulties in retrofitting an MVHR system into a houseboat, meant that there were particular challenges to overcome in designing the MVHR ductwork system for the houseboat. The houseboat is three times more airtight than most Passive Houses! As the client said: Mvhrr problem was exacerbated by the steel skin of the vessel being fase completely air tight: Contemporary family house in Leeds aiming for Passivhaus certification.

Minimising noise in an MVHR system Syudy more air you push through a duct the more turbulence is created, the louder the air sounds and the harder the fan has to work to push it through. Specifying the right ducting The large diameter and sheer amount of ComfoTube ducting required meant finding stusy from the unit to each of the rooms in the houseboat was an added challenge.

A radial design with two central manifolds was chosen so that individual sound attenuators to each valve would not be necessary. The Q Syudy will provide the necessary ventilation to clear the houseboat of VOCs and the client was able to close their windows and doors and run their heating as they headed into the cold London winter.

Eight-week turnaround from MVHR design to fully installed and commissioned The Q MVHR system is now up and running, with a total turnaround from Enhabit receiving the initial request from the client through to design, installation and commissioning of just eight weeks.

Excessively high or low Relative Humidity RH can cause discomfort and illness for occupants. Case study on the radical retrofit of a s ex-council house in Manchester, resulting in EnerPHit the Passivhaus standard for retrofits certification.

Old Forge Cottage is a newbuild 3 bedroom home mhvr in a rural village north of Leeds, certified to the Passivhaus standard. The Hen House, Sheffield. The Q MVHR system is now up and running, with a total turnaround from Enhabit receiving the initial request from the client through to design, installation and commissioning of just eight weeks.

Because so much air would be displaced regularly by the high flowrates, mvvhr risks of drying stuvy the air in the houseboat and lowering the Relative Humidity RH of the air in the houseboat were increased. Leave a Reply Cancel reply Your e-mail address will not be published.

A final word from the client: Meeting all these parameters for such an unusual project was challenging to say the least. These potentially dangerous VOCs tended to become particularly concentrated in the study room and the third bedroom, which did not have any natural ventilation from windows or draughts.

Case Study: Designing and installing a ventilation system for a London houseboat with poison air

The large diameter and sheer amount of ComfoTube ducting required meant finding passages from the unit to each of the rooms in the houseboat was an added challenge. It had to be extremely powerful to deal with our level of pollutant, way above anything you would normally use, and it had to be easy to install in such a tight space, so they created a computer model of the boat in which to plot the many complex runs of ducting we would need.

The amount of background airflow needed to continuously clear the air of these harmful build-ups of VOCs meant that the number of valves would have to be doubled to each room on the houseboat. Enhabit has strict parameters on acoustics, pressure drops and energy performance when designing any MVHR system, as we want the MVHR system to run as quietly, as comfortably and as efficiently as possible for inhabitants. When the VOCs eventually break down completely the Q will be re-commissioned at lower flow rates more suitable for a houseboat.

High levels of VOCs can cause sickness and discomfort, and the effects of these VOCs was exacerbated by the incredibly-high airtightness level of the boat at 0.

Case Studies

The more air you push through a duct the more turbulence is created, the louder the air sounds and the harder the fan has to work to push it through. Case study on Passivhaus newbuild 2 bedroom house built in a conservation area in Powys. To mitigate these noise issues Enhabit upsized the ComfoTube ducting from 75mm to 90mm diameter, so it could push through more air at lower air speeds.

A low energy active mechanical ventilation with heat recovery solution was required to move the air and clear it of VOCs, and the situation was urgent.

Enhabit was contacted last autumn by a couple living on one of the largest houseboats in London, moored permanently in a marina in East London.
