Volatile Organic Compounds (VOCs)

What are VOCs? Volatile organic compounds (VOCs) are chemicals that vaporize and enter the lungs through normal breathing. VOCs are ingredients in paints, cleaning products, and adhesives. Building materials such as carpet, linoleum, composite wood products, and...

Zero Net Energy Homes

 Purpose of ZNE A ZNE home is one where the value of the energy produced by on-site renewable energy resources is equal to the value of grid energy consumed annually. Net-zero is measured by the Time Dependent Valuation (TDV) Metric. TDV is the cost-effectiveness and...

Balanced Ventilators

Balanced Ventilation Systems Balanced ventilation systems exhaust stale air and provide fresh air through a ducted distribution system. Of all the ventilation schemes, they do the best job of controlling pollutants in the home. Balanced systems move equal amounts of...

Installing CO and Smoke Alarms

Install Carbon Monoxide and Smoke Alarms Carbon monoxide and smoke alarms are now common products that the building code requires in all new homes. These alarms wake occupants if the concentration of CO or smoke becomes dangerous. Building owners can buy combination...

Insulation Performance Factors

Insulation’s ability to resist heat flow is measured by its R-value. “R” stands for “resistance.” Like many numerical values, there are two R-values and we refer to both as “R-value.” The metric R-value is also known as RSI or R for resistance in the “Systeme...

Filters for Indoor Particulates

Airtightness and Resistance Effects Most of the hazardous particulates enter the home from outdoors. The airtightness of a home is the most important factor to minimize airborne particles, known as PM2.5, in indoor air. PM2.5 means particles of less than 2.5 microns...
