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.

“Besides the contaminants we find outside, we also have indoor contaminants. There are pollutants typical of homes such as dust, spores, moulds, and those produced by human activities like cooking and house-cleaning, that contribute to the release of additional damaging substances,” expert warns
Indoor air pollution kills 4.3 million people globally every year, according to the World Health Organization (WHO). The main causes are heating and cooking practices that produce high levels of toxic substances, such as fine particles and carbon monoxide.

The AIVC workshop: “Is ventilation the answer to indoor air quality control in buildings? Do we need performance-based approaches? will take place in Brussels, Belgium on 14-15 March, 2017. The event aims to identify the pros and cons of performance-based approaches and metrics that can be considered to assess the indoor air quality (IAQ) performance of ventilation systems, as well as to draft guidelines for their use in standards and regulations.

38th AIVC - 6th TightVent & 4th venticool Conference, 2017 | Ventilating healthy low-energy buildings
The need to reduce the energy demand of buildings is reflected in the legislation and policies of many countries. However, there is increasing concern about their adverse effects on occupant health and comfort in low energy buildings. These issues are being considered by some international energy conservation policy initiatives for buildings that seek to simultaneously reduce energy demand and provide acceptable indoor environment quality.

Over the years, different approaches and indices have been used to define indoor air quality. The most frequently used, recognised by the public, and equated with indoor air quality are, of course, ventilation rate and concentration of carbon dioxide. Other approaches define the levels of dissatisfaction with acceptability of indoor air quality, as expressed by the building occupants. At some point in time, the total concentration of airborne volatile organic compounds was proposed, as well.

This paper reviews and summarises research studies of residential energy efficiency (EE) and related ventilation upgrades, discusses ways that programmes monetise occupant health co-benefits, highlights innovative programmes that combine EE and health-focused home repairs and identifies where research gaps exist, and/or where research can be improved and leveraged.
Key study findings include:
