Why Do Green Buildings Matter for Air Quality?
Buildings account for a significant portion of energy use and air pollution, especially in urban areas.
Conventional buildings often contribute to poor air quality due to the emissions from heating, cooling, and lighting and the off-gassing of toxic chemicals from building materials.
In contrast, green buildings are designed to enhance indoor environmental quality while lowering outdoor air pollution through sustainable practices.
Improving Indoor Air Quality
Reducing Indoor Pollutants
Green buildings aim to maintain air quality using materials emitting fewer harmful substances.
Conventional construction often involves materials that release VOCs and other indoor pollutants, negatively impacting occupant health.
Using low-VOC materials such as paints, sealants, and adhesives significantly reduces indoor air pollution in green buildings.
Sustainable materials like formaldehyde-free insulation or recycled construction products contribute to a healthier indoor environment.
Effective Ventilation Systems
Ventilation systems play a crucial role in maintaining air quality inside green buildings. Proper ventilation helps to filter out indoor air pollutants and introduce fresh, clean air. Some features used to achieve this include:
- Mechanical ventilation with heat recovery (MVHR): Balances temperature and air exchange to improve energy performance and indoor air quality.
- Natural ventilation strategies: Green building design often incorporates windows and vents that can be manually adjusted, allowing for natural airflow and reducing the need for mechanical systems.
- High-efficiency particulate air (HEPA) filters capture fine particles and allergens, ensuring better indoor air.
Controlling Humidity and Moisture
Excess moisture in buildings can lead to mold growth, a major contributor to poor air quality. Green buildings are designed to control moisture levels using water-resistant materials and installing systems to manage humidity effectively.
This helps maintain good indoor air quality and prevents mold-related health problems.
Enhancing Outdoor Air Quality
Lowering Greenhouse Gas Emissions
Green buildings contribute to reducing greenhouse gas emissions by using renewable energy sources, such as solar or wind power.
This shift to clean energy lowers carbon dioxide emissions and decreases the overall environmental impact.
