    Thermal Comfort, Lighting and Acoustics


To date the sustainable commercial building sector in Australia has focused primarily on energy, due in large part to the mandatory disclosure provisions of the National Australian Built Environment Rating System (NABERS). Other dimensions of building sustainability such as Indoor Environmental Quality (IEQ) are less well developed. But widespread concerns about occupant productivity is shifting the spotlight onto building IEQ performance. Our new approach to IEQ measurement centres on small, low-cost, desk-based monitors (SAMBA) with sensors for thermal comfort (air and radiant temperatures, air speed and humidity), acoustics (SPL), lighting (lux) and air quality (CO2, CO, TVOC, Formaldehyde and PM10). Low unit costs make it feasible to place SAMBAs in each HVAC zone of complex commercial buildings. The SAMBA network architecture is based on a self-forming mesh network that does not require access to the host organisation’s ICT infrastructure. Measurements are relayed wirelessly to a central SAMBA gateway within the building that transmits data through the cellular network to the IEQ Laboratory’s server every 15 minutes. Various IEQ indices and compliance metrics are calculated in real-time before being presented to an online IEQ dashboard to which the building operator has access.
