Green Hammer

A Breath of Fresh Air

A building that mimics a healthy living system best supports our health. Paramount to the health of any living system is fresh air. A crucial first step towards healthy indoor air is the elimination of Volatile Organic Compounds (VOCs) like 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, 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. 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.
