How to Improve Indoor Air Quality in Commercial Spaces: Insights and Strategies

July 11, 2023

As a commercial property owner or manager, ensuring high indoor air quality (IAQ) is a primary responsibility. Not only does this create a healthy and comfortable environment for your tenants, but it also enhances the reputation of your property and could increase its value over time. So, how can you reliably maintain and improve the indoor air quality of your building?

This article takes a deep dive into IAQ, shedding light on a broad array of strategies for its improvement, including leveraging the power of analytics technology like the PEAK Platform's Indoor Environment module. By the end of this post, you'll be equipped with an arsenal of actionable insights to improve your property's indoor air quality.

Understanding Indoor Air Quality (IAQ)

Indoor Air Quality (IAQ) refers to the air quality within and around buildings and structures, with emphasis on the health and comfort of building occupants. IAQ is measured based on several factors including temperature, humidity, ventilation, and levels of certain pollutants such as Carbon Dioxide (CO2). 

To maintain fresh air ventilation, commercial properties often use devices like Outside Air Fans (OAFs). However, if these essential devices fail or are manually overridden, the indoor air quality can rapidly deteriorate, endangering the well-being of building occupants.

The Significance of High Indoor Air Quality

The importance of maintaining high IAQ cannot be overstated. Firstly, it promotes a healthier environment for tenants, mitigating the risk of health conditions like Sick Building Syndrome, a medical condition where occupants of a building experience acute health effects that seem to be linked to time spent in a building, but no specific illness or cause can be identified.

In addition, a high-quality indoor environment enhances productivity, as numerous studies have established a direct correlation between comfortable, well-ventilated spaces and improved work efficiency.

Furthermore, compliance with health and safety standards necessitates maintaining high IAQ. Failure to comply can result in substantial penalties, damage to the building's reputation, and potential legal issues.

The Role of Indoor Air Quality in the Indoor Environment Rating

Indoor Air Quality (IAQ) is a pivotal component of the Indoor Environment rating, often interchangeably referred to as the Indoor Environment score. This rating serves as a crucial benchmark in evaluating the comprehensive quality of a commercial property. IAQ encapsulates the air quality both inside and around the building, along with other elements like temperature, lighting, and acoustics, all with an emphasis on ensuring the health and comfort of the building's occupants.

Improving the IE rating, with a key focus on IAQ, can bring about a considerable elevation in a property's market value. It underscores the building's commitment to quality, adherence to industry standards, and competitive edge in the marketplace, resulting in a potential increase in rental revenue and demand. Thus, strategic enhancement of the IE rating, largely influenced by IAQ, can decisively improve an asset's long-term value and market appeal.

Practical Strategies for Improving Indoor Air Quality

Maintaining and improving Indoor Air Quality requires a holistic approach that combines technology with various essential strategies. As a property owner or manager, it's crucial to implement these fundamental practices to ensure a healthy indoor environment. Here, we outline key strategies that can significantly enhance your property's air quality:

Regular maintenance and cleaning

Consistent and thorough cleaning can reduce the levels of dust, allergens, and other pollutants in the air. Remember to clean air ducts and replace air filters regularly to maintain your HVAC system's efficiency.

Proper ventilation

Ensure your building has adequate ventilation. This includes having operable windows and efficient ventilation systems to reduce the concentration of pollutants indoors. Regular checks on systems such as Outside Air Fans (OAFs) are crucial to ensuring they're functioning as intended.

Controlling humidity

High humidity can lead to mould growth, while low humidity can cause respiratory problems. Aim to keep indoor humidity levels between 30% and 50% for optimal comfort and health.

Minimizing indoor pollutants

Where possible, opt for low-VOC (Volatile Organic Compounds) materials and products to reduce indoor pollutants. This could apply to everything from the paint you use on the walls to the cleaning products utilized by your janitorial staff.


Indoor plants can contribute positively to indoor air quality by absorbing pollutants, producing oxygen, and increasing humidity. However, they should be chosen and maintained carefully to avoid becoming a source of allergens.

Use of building analytics technology

Embrace smart technology, like the PEAK Platform, to proactively manage and improve your IAQ.

PEAK’s Indoor Environment module continuously tracks thermal comfort and relative humidity against ideal comfort conditions and control setpoints. In real time, it covers all zones, floors, and tenancies, ensuring that your energy-saving initiatives do not compromise the tenant experience.

The platform provides the ability to proactively manage tenant comfort, instantly act on anomalies, benchmark performance, and ultimately boost Indoor Environment ratings.

Real-world Impact: A Success Story from PEAK

The PEAK Platform's Indoor Environment module demonstrated its effectiveness at an A-grade office asset in Brisbane. When one of the building's critical Outside Air Fans ceased operating, leading to rapidly escalating CO2 levels, the PEAK Platform promptly alerted the Operations Manager. 

A ticket was assigned to the onsite mechanical technician, who quickly rectified the situation. The CO2 levels, which had peaked at 1,200ppm, were rapidly brought down to safe levels before significantly impacting the tenant experience and wellbeing.
