The mechanical ventilation system is now up and running in the house. A Passivent iHybrid system was chosen in the end after much consultation between the design team members, manufacturers and the resident.
The key concern was to avoid overheating. Although energy modelling demonstrated a low risk of overheating on a theoretical level, it was still a concern due to the pipe runs and heat sources within such a well insulated dwelling. For that reason, questions were raised about systems which had no summer bypass for the heat recovery system
and the iHybrid system seemed an excellent solution.
Dennis Bates of Passivent said of the system:
A ventilation system only performs as it should provided that it is installed correctly. Air tightness within the system and unobstructed clear air routes are key to ensuring that moist, stale air is removed from the property, and fresh clean air is fed in, so not causing any potential excess moisture, leading to damp and mould growth.
Noting that installation is a key factor, Passivent have a team of approved Mastercare installers, whom are trained by the manufacturer to ensure that every project not only has the right system installed, but it installed to the highest quality, providing the promised levels of ventilation. The unique iHybrid system which was used on the project combines Heat Recovery with natural Passive Stack Ventilation, providing energy savings and i
ncreased longevity over standard heat recovery systems, was installed by one such Mastercare Installer, Brooklyn PSV. The quality and professionalism of the approved installer network means that the system was commissioned and will continue to operate as designed throughout it's life, providing occupants with fresh clean air.'
The ventilation fans will now be monitored for 2 years to ascertain the reduction in electricity consumption due to the passive stack principle being adopted during summer months.
