Dynamic PIV brings together both Dynamic Insulation and Positive Input Ventilation (PIV) to enable builders and designers to meet today's ever-increasing demands for energy-efficiency and carbon reduction.
A simple building-fabric solution, Dynamic PIV easily integrates the insulation and ventilation system to capture the heat energy escaping through the building fabric and pre-warm incoming air. Designed for conventional thin wall construction, Dynamic Insulation delivers the U-Values, SAP DER points and Carbon Reduction to help meet all 2010 through 2016 regulations in one simplified system that is free from maintenance and complex ventilation systems or add-on technologies.
EnviroVent's Dynamic PIV is a whole house ventilation system, which has been tested by BRE to specifically comply with Dynamic Insulation, achieving a specific fan power as low as 0.2 W/l/s.
The Dynamic PIV connects to the cavity and draws the warmed air through the Dynamic Insulation at a continuous rate into the property at ceiling level. The air that is introduced can be between 4-8°C warmer than the external temperature. The home is gently ventilated from a central position on a landing to dilute, displace and replace moisture laden air, controlling humidity levels and ensuring good all year round indoor air quality.
Dynamic PIV brings additional benefits to both the home and residents:
Redistribution of Heat
Warm air accumulates at ceiling level. This air can be up to 7°C higher than the internal air at ground level. By introducing an almost imperceptible air supply into the property from the loft space, the EnviroVent Dynamic PIV helps to redistribute heat around the home, reducing space heating costs.
No Requirement to Open Windows
During the heating season, significant energy is lost by opening windows to reduce humidity and condensation. By installing the Dynamic PIV and providing fresh air into the home, humid air is displaced without the need to open windows.
Low running costs
Fitted with the latest low watt motor technology, the Dynamic PIV achieves a low energy consumption of around 4 Watts.
Dynamic Insulation works by using the heat energy escaping from the building to pre-warm incoming air through the insulation layer, effectively turning the building envelope into a heat exchanger.
Proven to raise the temperature of incoming air by as much as 8°C, Dynamic Insulation delivers a 25% improvement in energy efficiency over traditional insulation products. Dynamic Insulation products are designed for use in traditional new build and refurbishment construction as a maintenance-free, building-fabric solution that requires no change to familiar building methods, expensive additional ventilation systems or thermal technologies.
