Healthy Indoor Air

Even at low concentrations, air pollutants can cause health problems, including asthma, allergies and lead poisoning. At Green Hammer, we know how important clean, fresh air is to human health. That's why we create buildings that are designed to mimic healthy ecosystems—buildings that provide fresh air and clean water, create and conserve energy, and minimize toxins and eliminate them whenever feasible.

A crucial first step towards healthy indoor air quality is the elimination of Volatile Organic Compounds (VOCs) such as urea-formaldehyde from all of Green Hammer’s work. VOCs are pervasive in paints, sealants and glue-based wood products that are all too common in the construction industry. They off-gas toxins into our indoor air and over time, can be very hazardous to our health.

To keep healthy air flowing through a home, we recommend a heat recovery ventilator (HRV) as a part of any holistic building performance upgrade. HRVs are designed to provide continuous fresh, filtered, outdoor air to bedrooms and living spaces to improve healthy indoor air quality, while exhausting stale air from our bathrooms and basements. The heat leaving from the exhaust air transfers to the incoming air without cross-contaminating air streams. The result is continuous comfortable, fresh, filtered outdoor air – even on the coldest days.

Relative Humidity

The relative humidity level (RH) of our air is also a critical component of healthy indoor air quality in the Portland area. ASHRAE (American Society of Heating, Refrigerating and Air Conditioning Engineers) studies have shown that RH between 40%-60% is optimal for our personal health. Client feedback and our experience monitoring indoor air quality have given us the expertise we need to strike this optimal balance in comprehensive performance upgrades.
