SUSTAINABLE SUPPLIER OF THE YEAR – BUILDING PRODUCTS
Passivent Commercial WINNER
K in the early stages but due to their extensive experience and knowledge in the field were able to create the new, improved product range. Again, higher specifications were set for air leakage and 0.54m3
/hour/m2 was achieved as the
result of the skill and know-how of the specialist research and development team.
Potential Applications The AIRCOOL Façade Ventilator is an ideal product for use in commercial buildings such as; schools, universities, offices, hospitals and libraries.
COMMUNICATION Passivent maintain a continual policy of internal and external marketing to ensure all product development and new product launches are fully communicated to all stakeholders. All employees are encouraged to learn about/ and contribute to external environmental factors. Passivent work in partnership with industry bodies including CIBSE to develop future strategies.
COST EFFECTIVENESS Passivent are able to offer cost effectiveness not only through the value of the product, but also through the low cost energy products. Once Passivent’s products are installed there is virtually no maintenance and low/no running costs.
PARTNERSHIP Passivent continually strive to add value to the market place through partnerships. In the past Passivent have worked with Mitsubishi in developing their ‘mixed mode’ system and are currently working on a new product with Rehau. In addition to this, Passivent provide research to help inform Building Regulation, CIBSE, University research, SISLO research and

many more. Passivent also sponsor Greenpower which encourages school children to pursue an interest in mechanical engineering. Passivent work closely with the Greenpower Organisation and a local school: St Pauls and won the award for the best aerodynamics at the last national heat.
INNOVATION AND PRODUCT SELECTION
The AIRCOOL Façade Ventilator The AIRCOOL Façade Ventilator range is a range of controllable ventilators primarily for installation in external façades in commercial and similar buildings. The electrically-actuated ventilators provide controlled air intake and extract in natural (passive) ventilation systems, and may also be used for air intake and extract in mechanical ventilation systems.
They are particularly suitable for night cooling strategies, where daytime heat build-up is dissipated from the structure during the night, producing lower internal air temperatures with a reduced need for daytime cooling or air conditioning.
Specific Innovation in terms of design, equipment or application The AIRCOOL Façade Ventilator’s new controllable louvres offer additional air tightness and an improved U-Value. When tested to BS6375: Part 1: 1989, the closed ventilators provide an air leakage of 0.57m2
and 9.7 m3
/hour/linear meter of blade joint /hour/m2
2Pa the air leakage figure is around 0.54m3
/hour/m2 at 1.59Wm2 K. These are fantastic
achievements and are well above industry standards.
The AIRCOOL Façade Ventilator changed from PVC controllable louvres to aluminium with ABS thermal break, making them even more environmentally friendly and more effective.
CARBON REDUCTION COMMITMENT Low carbon benefits The AIRCOOL Façade Ventilator has achieved triple bottom line benefits: i) Environmental Sustainability • ISO 14001 Environmental Management
• The Primary construction materials are Aluminium and ABS which are 100% recyclable making them sustainable
ii) Social Sustainability • Aesthetically pleasing
at 50Pa pressure. At . The U-Values averaged
Special challenges leading to the development of the AIRCOOL Façade Ventilator Passivent set very high product specification briefs for all new products and the AIRCOOL Façade Ventilator is no different. The team came across some challenges achieving a U Value of 1.56Wm2
