Air Purification at Zero Incremental Cost: What many architects and developers still don’t realise is this: When designed correctly, air purification does not need to increase project cost at all. In fact, when aligned with ASHRAE Standard 62.1’s Indoor Air Quality Procedure (IAQP), it can reduce HVAC capital expenditure, lower energy demand, and accelerate compliance with green building certifications such as LEED, WELL, and Fitwel. This is not an add-on.It is a design optim

ASHRAE 62.1 - Indoor Air Quality Procedure (IAQP) 2025. Why ASHRAE 62.1 - Indoor Air Quality Procedure Matters in HVAC Design In hot-climate regions, outdoor air dominates: Cooling load HVAC system sizing Energy consumption IAQP enables engineers to decouple IAQ performance from outside air volume, unlocking opportunities to: Reduce ventilation rates Downsize HVAC equipment Lower peak and annual energy demand.

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. 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 In hot, dusty regions such as the GCC and wider MENA, that assumption is increasingly outdated - and costly.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.

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.

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: 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

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.

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
