IAQ - indoor air quality

CR 17: 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

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 summarizing 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.

Defining Indoor Air Quality

The first ASHRAE IAQ conference in 1986 was held “to review the latest research in indoor air pollution and provide missing current data for Standard 62” with the understanding that, “the indoor environment should minimize any impact on health and should be free of any impact on comfort, and control should minimize the use of energy.”1 Implicit in this statement is the belief that the performance measures needed to realize this goal could be defined in practical terms.

Indoor Air Quality in New Zealand Homes and Schools

This guide, released by the Building Research Association of New Zealand (BRANZ), is a literature review of recent research on indoor air quality that is relevant to New Zealand’s indoor environments (residential houses, schools, preschools and age care facilities). The document looks at the health effects, the pollutants and the building characteristics. Where possible, New Zealand research is presented. Emphasis is placed on gaps in the knowledge in order to identify future research in New Zealand.

Assessment of ventilation systems efficiency in office buildings, related to indoor volatile organic compound concentrations

The objective of this study is to develop an approach concerning the integration of volatile organic compounds (VOCs) emissions due to office equipment in computational fluid dynamics (CFD) simulations, in order to assess the indoor air quality (IAQ) in offices. The transport and diffusion phenomena of VOCs are taking into account in the CFD model by means of conservation equations of the mass fraction, written for each VOC that is intended to be considered in the simulation.
