Indoor Air Quality Design and Control in Low-energy Residential Buildings- Annex 68 Subtask 1: Defining the metrics -- In the search of indices to evaluate the Indoor Air Quality of low-energy residential buildings -- AIVC Contributed Report 17


This report is one of the deliverables of the International Energy Agency Energy in Buildings and Communities programme (IEA EBC) Annex 68: “Indoor Air Quality Design and Control in Low-energy Residential Buildings”.


The document was developed by Subtask 1 (ST1) of the annex, which sets the frame for defining the target pollutants and the metrics needed to quantify IAQ level of low-energy residential buildings. This report is a summary of the approaches, developments and results achieved in this subtask.


The objective of present work was to develop the metric that assess the performance of solutions securing high indoor air quality in low-energy (modern) residential buildings. This was achieved by summarising data on the levels and types of gaseous pollutants and particulate matter in low-energy buildings and comparing them with the existing exposure limits for pollutants. The result is a graphical signature showing whether any pollutant level exceeds short-term and long-term exposure limits, and indicating the associated healthy life years lost; the signature is supplemented with the information on energy use in a building.
