Indoor Environment Assessment.
A healthier environment for everyone.
A healthy indoor environment is not just a nice-to-have, it is now a core expectation for commercial tenants and a key driver of tenant retention, productivity, and leasing success. Poor indoor air quality can lead to a range of health risks, including respiratory irritation, fatigue, headaches, and the exacerbation of asthma or allergies. Long-term exposure to elevated levels of particulate matter, mould, or volatile organic compounds (VOCs) may even result in chronic health conditions and potential legal liability.
Ensuring a safe and comfortable workspace requires more than reactive maintenance. It demands a proactive, data-driven approach to indoor environmental management. Building owners and facility managers should monitor and optimise indoor conditions across a range of parameters:
Air quality — including levels of particulate matter (PM2.5), carbon dioxide (CO₂), VOCs, and mould spores
Thermal comfort — consistent indoor temperatures and humidity control year-round
Lighting quality — natural and artificial lighting that supports comfort and productivity
Noise levels — appropriate acoustic conditions for focused work and wellbeing
Ventilation and filtration — adequate fresh air supply and system performance through HVAC monitoring
NettZero provides quick and cost-effective indoor air quality reports for office and retail premises, helping to ensure the provision of a healthy and safe environment for your tenants. We offer both NABERS Indoor Environment Ratings and independent Indoor Air Quality assessments.

A healthier, more productive workplace
Indoor environmental quality isn’t just about comfort, it directly impacts how people feel and perform at work. Forward-thinking building owners are now investing in healthier spaces to attract and retain tenants. As NABERS highlights, even simple features can yield measurable benefits to wellbeing and productivity across the workforce:
“Features of healthy offices, such as natural light, good ventilation and plants are proven to increase productivity by 8% and wellbeing by 13%.”

NABERS Indoor Environment ratings are recognised by both Australian and global reporting schemes including:
- WELL International Building Standard
- Green Building Council of Australia
- Green Star Performance
- GRESB
Why Indoor Environment Quality Became a Post-COVID Priority for Tenants and Landlords
Since COVID, indoor environmental quality has become a top priority for tenants and a critical consideration for building owners and managers. The pandemic heightened awareness of airborne transmission, ventilation performance, and the role that indoor spaces play in occupant health and wellbeing. As a result, expectations have shifted. Tenants now seek buildings that can demonstrate strong air quality, thermal comfort, and environmental control.
This growing focus is not just about safety, it’s about confidence. In a competitive leasing market, buildings that can verify their indoor air quality and comfort levels have a clear advantage. Certifications like NABERS Indoor Environment Ratings are increasingly used to differentiate assets, improve ESG credentials, and meet evolving tenant demands.
Some commercial tenants now require indoor environmental quality assessments and performance benchmarks to be embedded directly into lease agreements, making this a compliance issue as well as a competitive one.
By investing in indoor environment assessments and proactive monitoring, owners and facility managers can enhance tenant retention, reduce complaints, and align with best practice standards in healthy building management, an investment that pays off across the board.
