Buildings are getting tighter to save energy while COVID is drawing attention to the importance of proper ventilation. How much ventilation is needed? For residential buildings, there’s a widely accepted standard.
ASHRAE 62.2 “Ventilation and Acceptable Indoor Air Quality in Low-Rise Residential Buildings” Standard is a national standard that provides minimum requirements and methods for achieving […]
Can a home be beautiful, powered entirely by solar energy, use sustainable heating and cooling systems and save it’s owners roughly $3,500 a year? Why, yes it can. Just ask Joanne Coons, who built her award winning, single-family, Net Zero Energy Home in 2010. Sustainable Woman Joanne talks Net Zero standards, efficient appliances and goods, her […]
There is much debate within the building science community about how much ventilation is enough.
Building science as a discipline has to deal with a lot of messy, noisy data, entrenched mythologies, and strong tendencies towards confirmation bias.
On the other hand, public health as a discipline has to deal with a lot of messy, noisy data, […]
Twenty years ago a colleague gave me a portable carbon dioxide (CO2) monitor to use during my training sessions. These sessions were often in small, inadequately ventilated rooms loaded with too many breathing trainees. Tony suggested that I try to determine at what CO2 level I noticed my trainees’ attention started drifting away. After following […]
