Due to the higher insulation and the air-tightness requirement in modern buildings have resulted NBS(New Building Syndrome) and SBS(Sick Building Syndrome) of IAQ problems. Therefore, energy efficient way of solving such IAQ issues are of major concern in these days and areas. This paper introduces a new technology and method to improve IAQ performance
as well as to improve building energy performance with a DI(Dynamic Insulation) concept. The main idea to meet the goal is to use the DI concept similar to a heat recovery concept to prevent the heat loss path within the air path inside the dynamic insulation. The characteristic of the dynamic insulation is that the lower U-value as the higher air velocity through the DI.
The porous media such as HEPA filter improves the IAQ to filter out the PM10 particles and other unhealthy particles. A energy performance simulation study has been conducted to show the energy impact of porous DI over the static insulation material. A twin test cell with a DI was modeled and simulated to show the DI energy saving impact for different ACH's.
The results show that up tp 9 % energy with 2 ACH could be saved in the case with DI replaced in south faced insulation compared to the conventional insulation.
