Problem Solving For Your Home
People spend 80 - 90% of their time indoors - at work, school and home. An energy efficiency home controls the flow of air, heat and moisture through the home. An efficient home maintains moderate temperatures, low humidity and increased air quality.
10 to 50 litres of moisture are released inside a house each day. Humidity levels over 40% can create air quality problems. City Green advisors will show you how to reduce condensation and fogging on windows, staining on walls and ceilings, peeling paint, mould growth and odors.
When humidity is above 50%, airborne diseases become more difficult to control. To protect health and houses, all moist, stale air should be replaced with fresh air every 3 to 4 hours.
Finding the balance between minimizing air leaks and ensuring appropriate ventilation is critical. City Green's Certified Energy Advisors are trained to assess your home's energy needs based on a 'house as a system' building science approach. Only the "house as a system" building science approach to retrofit planning will prevent problems that single product installations may cause.
Potential Issues:
*Installing double pane windows may increase humidity issues such as mold and condensation if proper ventilation isn't added
*Adding insulation may damage the building envelope if moisture barriers aren't put in place
*New range hoods and other mechanical ventilation concerns may cause mid-efficiency furnaces to backdraft or spill dangerous carbon monoxide gas
