Air Quality Consultants -Sydney
Poor air quality near a childcare centre, aged care facility, or residential development isn’t just a compliance checkbox — it’s a real health question for the people who’ll spend the most time there. Young children breathe faster than adults relative to their body weight and are more vulnerable to airborne pollutants during critical stages of lung development (WHO, 2024). Older residents in aged care are similarly more susceptible to respiratory and cardiovascular effects from poor air quality. And for multi-storey residential developments, air quality near lower floors and podium-level open space is increasingly scrutinised by councils as apartment living intensifies across Sydney.
Enviro Corp's air quality consultants prepare Air Quality Impact Assessments for:
- Childcare centre development applications — addressing Control C26 of the NSW Child Care Planning Guideline
- Aged care facility developments — a sensitive-receiver category
- Multi-storey residential and mixed-use developments — including podium-level open space, lower-floor amenity, and proximity to traffic corridors
- New homes and smaller residential developments — due diligence and DA support for sites near roads or industrial areas
All assessments use the same EPA-approved atmospheric modelling methods (AERMOD) used for commercial projects — applied with specific attention to the sensitivities of the people who'll actually occupy the space.
Why Air Quality Assessments Matter for Childcare Centres
Childcare centre development applications are increasingly scrutinised for air quality impact — and for good reason. Young children spend the majority of their waking hours at these facilities, often in outdoor play areas directly exposed to nearby traffic, industrial, or construction emissions.
The specific rule that drives this: Control C26
Under the NSW Child Care Planning Guideline (2021) — the assessment framework every consent authority in NSW must formally consider under the State Environmental Planning Policy (Educational Establishments and Child Care Facilities) 2017 — Control C26 requires:
“Locate child care facilities on sites which avoid or minimise the potential impact of external sources of air pollution such as major roads and industrial development.”
This is the specific clause councils rely on when requesting an air quality report for a proposed childcare centre.

Air Quality Assessments for New Homes & Residential Developments
If you’re building a new home, renovating, or developing residential property near a busy road, industrial area, or existing licensed premises, an air quality assessment can identify potential issues before they affect your family or your development approval — rather than discovering them after move-in.
Air Quality Assessments for Development Applications (Commercial & Industrial)
Enviro Corp also prepares Air Quality Impact Assessments and Management Plans for commercial and industrial development applications, using atmospheric dispersion modelling in accordance with the Approved Methods for Modelling and Assessment of Air Pollutants in NSW. Assessments incorporate meteorological data (wind speed and direction) and site-specific parameters, and are prepared for Council approval.

Frequently asked questions
Not all, but many councils request one where a proposed centre is near a busy road, industrial area, or other potential pollution source — this is driven specifically by Control C26 of the NSW Child Care Planning Guideline (2021), which requires childcare facilities to avoid or minimise exposure to air pollution from major roads and industrial development.
well-prepared, proactive assessment reduces the risk of council imposing unnecessary design constraints or requesting further information — without one, councils may assume worst-case conditions.
No — this page covers Air Quality Impact Assessments for development applications (predictive, pre-construction modelling of outdoor/ambient air quality). If you need testing of the air inside an existing building, see our Indoor Air Quality Testing page.
The typical turnaround for a childcare/residential DA assessment is 2 – 3 weeks.
It depends on site location and complexity.
