Flagship AirMaster Smart Mechanical Ventilation Awarded Passivhaus Component Certification
SAV Systems is proud to announce that the AirMaster AM 1000 has been awarded Passivhaus Component certification in conjunction with their Danish partner, Airmaster A/S. The flagship AM 1000 is the first decentralised, duct free, mechanical ventilation unit with heat recovery (MVHR) on the market to be awarded the certification. This enables the AirMaster AM 1000 to be used in Passivhaus school buildings.
Our time working with the City of Edinburgh Council (CEC) inspired SAV Systems to undertake Passivhaus certification. CEC has set ambitious targets to achieve Net Zero by 2035, leading the council to apply passive house design principles to all their new schools. The core philosophy of passive house design is to create a comfortable and energy efficient building with minimal energy wastage. Alongside the need for improved energy efficiency, Passivhaus also offers the opportunity to create more comfortable learning environments for students, combatting the Scottish climate.
Ventilation plays a crucial part in two requirements of passive house standards: air tightness and space heating demand. Openings in buildings, such as windows and porous building materials can allow heat to escape, wasting the energy generated by the building. Consequently, Passivhaus buildings have high airtightness and low heat loss. However, in increasing the airtightness of a building to conserve energy, indoor air quality can suffer. Therefore, a mechanical ventilation solution is required to manage indoor air quality without wasting energy.
Adopting AirMaster as a school’s ventilation strategy is an effective choice for designing comfortable classrooms. Due to the decentralised design of AirMasters, the units can be installed easily in a range of different classrooms, making use of duct free air distribution. A typical classroom installation requires one AirMaster AM 1000 per room with intake and exhaust connection to outside. The AM 1000 can recover up to 90% of the room’s heat using an aluminium heat exchanger, reducing the building’s heat load and heat loss.
The certification of the AM 1000 makes available an innovative ventilation strategy that can improve indoor air quality without sacrificing thermal comfort. Not only is this certification exciting for SAV Systems, but it is also exciting for decentralised mechanical MVHR as a ventilation strategy. With growing pressure on buildings to become energy efficient and comfortable, decentralised MVHR like AirMaster should play a vital role in the solution.
