BIOWALL’S IMPACT ON INDOOR AIR QUALITY AND ENERGY
Impact/Purpose:
Energy efficient buildings typically have high levels of insulation and seal the leakage paths for outside air infiltration. Unfortunately this can lead to poor indoor air quality as an unintended side effect. Innovations are needed to maintain optimal levels of human comfort and productivity in highly efficient buildings. The Biowall is a new concept for maintaining high levels of indoor air quality and has the potential to reduce HVAC energy use by reducing outside air requirements for buildings. The device consists of a living plant wall that is integrated into the HVAC system of a building. This technology leverages the natural ability of plants to reduce CO2 and remove VOC’s.
Description:
This project will collect data on air quality and energy consumption for a variety of Biowall configurations in a controlled laboratory environment. This data will be evaluated for statistical significance and used to develop and validate an energy/IAQ model of the Biowall. A successful Phase I effort will lead to a Phase II P3 project to deploy an improved Biowall in a demonstration home.
