Project Summary Report - IEA EBC Annex 68 Indoor Air Quality Design and Control in Low Energy Residential Buildings
New dwellings or deeply renovated existing dwellings are designed to be energy efficient, and have airtight structures. This leads to a risk of high indoor pollutant loads due to activities and emissions from materials in contact with indoor air. Ventilation must be dosed at the right volume of clean air, efficiently distributed in the occupant zone and with proper scheduling in order to keep indoor pollutant concentrations low, while not increasing the energy need. Building designers, contractors, owners and operators, and decision makers need the newest knowledge on how to operate ventilation to achieve this. The project has focused on new and existing residential buildings, although it should be underlined that many findings may also be relevant to other building types. At the onset of the project, the existing indicators for indoor air quality (IAQ) were reviewed and indicators were defined that would specifically facilitate the other subtasks in this project. The IAQ indicators to be studied were documented in a report, which collected state of the art information and suggested a principle in the form of a “dashboard” on how to balance the combination of the most significant among many pollutants to be considered. The dashboard also highlighted the energy performance aspect. A main result of the project is an easy to understand and practically applicable collection of experiences with design and operational strategies to achieve optimal energy performance and high IAQ in residential buildings. The collection is intended for those involved in the construction and maintenance of buildings. Furthermore, the project presents a modelling framework and design tools, suitable for integrated and coordinated design of buildings with low energy consumption and high IAQ. With regards to pollutants in buildings, data and models have been applied on sources and sinks of pollutant emissions to estimate the net pollutant loads over time under realistic environmental conditions. This is supported by databases on the ...
