Architect and Builder Information
If you are designing or building homes and looking to aim for higher than standard of performance, HiPer Haus can help you with the design, supply, integration and commissioning of MVHR systems, Blower door (air tightness) testing and hot water heat pumps.
When should we consider MVHR for our projects?
MVHR systems provide controlled ventilation and are most effective when installed in properties with good air tightness levels. For the best operation of a MVHR system we recommend achieving an air tightness level of at least 5 ACH at a pressure test (q50), with an ideal target of below 3 ACH.
We believe setting air tightness goals is essential for both new builds and refurbishment projects.
Other criteria for installing MVHR (other than air tightness)
1. Noise: if a property suffers from noise, e.g. traffic or airport, MVHR systems with adequate silencers will provide a good solution for ventilation without the need to open windows. Additionally noise reduced glazing will help.
2. High condensation: MVHR systems will actively dehumidify when it is outside colder than inside.
3. Air quality: if the air quality is problematic, various kind of filtration in MVHR systems can deal with pollen, rural and industrial smells.
Intergrating MVHR into your projects
When integrating a Mechanical Ventilation with Heat Recovery (MVHR) system into a home, several important considerations need to be taken into account to ensure the system performs optimally and adds value to the indoor environment.
Space for ductwork
Centralised MVHR systems typically require sufficient room for the MVHR unit and the ductwork to run between the rooms. Considerations like where the main unit will be housed need to be thought through early in the planning stages. The duct for the system is generally installed within the thermal envelope (on the internal side of the insulation layer). If your home will not have a drop ceiling to enclose the ducts we can run the ducts over the ceiling timbers then the insulation can be installed over the top.
Space for MVHR units
An MVHR unit should be placed in a dedicated, accessible location such as a laundry, pantry or ceiling void. Enough room needs to be allowed around the unit for servicing, filter changes, and duct connections.
