IAQ Insights
Indoor air quality is no longer a comfort issue - it is a public health, productivity, and infrastructure challenge.
IAQ Insights is a curated source of evidence-based guidance, independent testing, and real-world implementation insight on indoor air purification and HVAC-integrated air quality solutions.
It is written for policy makers, ministries, healthcare leaders, developers, engineers, and facility owners who require more than theory. It reflects nearly two decades of practical experience delivering proven, independently validated air purification technologies across commercial, healthcare, education, hospitality, and government environments.
This is not opinion-led commentary. It is decision-grade intelligence designed to support policy, specification, and long-term investment in healthy, high-performance buildings.
Why Improved Indoor Air Quality Must Be Part of the Climate and Health Conversation
Why Improved Indoor Air Quality Must Be Part of the Climate and Health Conversation. The recent United Nations General Assembly and Climate Week drew attention to climate commitments, emissions targets, and long-term sustainability strategies. Yet one of the most immediate and actionable issues affecting human health and environmental performance is much closer to home: indoor air quality.

Why Green Buildings Fail Without Indoor Air Quality
Why Green Buildings Fail Without Indoor Air Quality. oor air quality in green buildings contributes to respiratory illness, fatigue, reduced cognitive performance, absenteeism, and lower occupant satisfaction. From a building performance perspective, it also drives higher energy use through excessive ventilation, oversized systems, and inefficient operation.
True sustainability requires balancing human health and environmental performance. This is where integrated IAQ strate

Ventilation strategies for Improved IAQ in the GCC
Ventilation strategies for Improved IAQ in the GCC. For decades, building ventilation strategies have been driven by a simple assumption: more outside air equals better indoor air quality. In hot, dusty regions such as the GCC and wider MENA, that assumption is increasingly outdated - and costly. Ventilation strategies for improved IAQ exist and are relatively easy to apply.

Why Indoor Air Quality in Oman Must Be a Priority for its Buildings
Why Indoor Air Quality in Oman Must Be a Priority, As Oman continues its transition toward a more sustainable and diversified economy under Oman Vision 2040, the performance of our buildings - and the environments they create - is coming under increasing scrutiny. While energy efficiency and water conservation remain central to this discussion, one critical factor still does not receive the attention it deserves: indoor air quality (IAQ).

Cooling, Humidity, and Health in the Gulf: Top Indoor Air Quality Trends
Cooling, Humidity, and Health. cooling is not simply a matter of comfort - it is a fundamental necessity for daily life and work. Extreme temperatures, high humidity levels, and frequent dust events make continuous air-conditioning essential in homes, offices, hospitals, schools, and commercial spaces.
What is often overlooked, however, is that cooling alone does not guarantee a healthy indoor environment.

How We Make Each Other Sick Indoors - And Why Improving Indoor Air Quality Is a Strategic Health Issue in the GCC
How We Make Each Other Sick Indoors. In hospitals, schools, offices, and hotels across the Gulf Cooperation Council (GCC) countries, people spend most of their time inside sealed, continuously air-conditioned buildings. In these environments, indoor air quality is no longer just a comfort issue - it has become a critical factor affecting public health, performance, productivity, and institutional reputation.

Data Centres and Mission-Critical Facilities: Improving Indoor Air Quality Beyond Humans
Improving Indoor Air Quality: Data Centres. When indoor air quality (IAQ) is discussed, the focus is almost always on people - health, comfort, productivity, and well-being. But in some of the most critical buildings in the world, the primary “occupants” are not humans at all. Data centres, control rooms, trading floors, broadcast facilities, and other mission-critical environments depend on something just as sensitive as human lungs: electronics.

IAQ - What Engineers Get Wrong About It
IAQ - What Engineers Get Wrong: Engineers are trained to be precise, evidence-driven, and standards-focused. That discipline has delivered safer buildings, better energy performance, and remarkable technical progress. Yet when it comes to air purification, even experienced engineers often make assumptions that limit performance, increase cost, or miss the real objective altogether.

Air Purification For MEP Consultants - What's Important?
Air Purification For MEP Consultants: MEP consultants sit at the centre of building performance. You translate client intent into technical reality, balance standards with budgets, and carry long-term responsibility for how systems perform once the building is occupied.
Yet air purification is still frequently misunderstood or under-specified at the design stage—not due to lack of competence, but because it is often treated as peripheral rather than integral to HVAC strategy

Mosques and Indoor Air Quality: High Occupancy, Long Dwell Times.
Mosques and Indoor Air Quality. Places of worship are among the most important shared indoor environments in the GCC. Mosques, churches, temples, and prayer halls welcome large numbers of people daily, often multiple times a day, and play a central role in community life. Yet from a building performance perspective, they present a unique and frequently overlooked challenge.

IAQ Mass Balance Calculations Don’t Need to Be Scary
IAQ Mass Balance Calculations: For many engineers, the phrase “mass balance calculations” immediately brings to mind dense equations, spreadsheets full of assumptions, and time-consuming iterations. As a result, mass balance is often perceived as a barrier - something that complicates indoor air quality (IAQ) design rather than enabling it.
The reality is far simpler.

IAQ & Mould: A Technical Appendix For Engineers
Mould Control, Humidity, and Bipolar Ionization in HVAC Systems. Mould growth within buildings is fundamentally an HVAC and moisture-management issue. In mechanically conditioned buildings, mould colonisation most commonly occurs at locations where temperature gradients, condensation, and organic particulates coincide, including:
Cooling coils and fin surfaces
Condensate drain pans and traps
Internal duct liners
Terminal units and fan housings
Envelope-adjacent conditioned sp

IAQ - Mould, Moisture, and Health: How AtmosAir Helps Control a Hidden Risk in Humid Climates
IAQ - Mould, Moisture, and Health. Mould is one of the most persistent and underestimated threats to indoor environments - particularly in coastal and humid regions. Unlike visible maintenance issues, mould often develops silently behind walls, within HVAC systems, and in conditioned spaces where moisture, heat, and organic material combine.
