Indoor air quality (IAQ) and energy efficiency are critical considerations in building design as more people become aware of their impact on health and productivity. They’re also intricately linked — a well-sealed structure with effective ventilation maintains fresh air and minimizes electricity waste.

Let's delve into innovative solutions for creating comfortable, sustainable spaces that prioritize occupant well-being while contributing to a more energy-efficient future.

Why Improve IAQ? 

IAQ is a critical aspect of a building’s overall performance. It encompasses air quality inside a structure, the presence of pollutants and the environment’s comfort level. Leaks through gaps in the building envelope allow outdoor contaminants to infiltrate the indoor space, compromising air quality and increasing the burden on HVAC systems.

The health implications are profound. Construction sites and recently completed structures often harbor toxins that pose significant risks. For workers, prolonged exposure can lead to severe respiratory issues and other serious health problems. Similarly, occupants may experience discomfort, intense allergies or even sick building syndrome. 

Poor IAQ can stem from various factors, such as insufficient ventilation, chemical emissions from construction materials, or the presence of mold and allergens. Add the increased heating and cooling costs from energy leakage, and you’ve got a highly inefficient building contributing immensely to climate change. 

Implementing Advanced Enveloping to Improve IAQ and Energy Efficiency

Mitigating the risks of poor IAQ and energy leakage requires investing in robust building envelope technologies. Here are some products you should consider.

Airtight Insulation

Enhanced insulation solutions are a critical component in preventing energy leakage. One such innovation generating industry buzz is the POWERSKIN PLUS smart facade, an EU-funded curtain wall system that can capture and store solar energy. This state-of-the-art product provides superior sealing and can be deployed on new constructions and retrofits. 

High-Performance Windows

Advanced window designs incorporate double or triple glazing, low-emissivity (low-E) coatings and gas fills. The low-E coverings reflect infrared energy, helping maintain indoor temperatures while allowing visible light to enter. Inert gases provide additional insulation by reducing heat loss through the window panes.

Mechanical Ventilation Systems

Poor IAQ from inadequate air circulation is a common problem in commercial buildings since most windows don't open. Mechanical ventilation systems ensure a continuous supply of fresh air, effectively removing stale air and pollutants without compromising thermal comfort. 

Energy and heat recovery ventilators are notable examples of this innovation, effectively exchanging stale indoor air with fresh outdoor air while minimizing electricity consumption. Growing demand for these products in the U.S. will likely see the market expand 38% by 2028. 

Air Purifiers and Scrubbers 

Integrating air scrubbers and purifiers into the building’s HVAC system can further enhance IAQ. HEPA-rated systems boast a 99.9% efficiency rating capable of filtering 0.3-micron airborne particles, providing additional protection for occupants. 

These devices are crucial for enhancing IAQ in newly constructed or remodeled buildings due to the increased pollutants at such worksites. Installing them also ensures compliance with OSHA’s  “safe breathing” zone requirements, which set a 0.1 parts per million permissible exposure limit within a typical eight-hour shift. 

Promote Healthy and Comfortable Indoor Spaces

Enhancing indoor air quality while reducing energy leakage is essential for creating sustainable and efficient commercial buildings. As the demand for healthier indoor environments grows, you should consider investing in these solutions to yield long-term benefits for businesses and employees.
