Most building codes require roof vents to expel moisture that could cause insulation or other building materials to deteriorate during winter. In summer, ventilation may reduce roof temperatures, thus lengthening a roof’s life. However, researchers are investigating whether attic ventilation is beneficial for all climates. For years, researchers have believed the cooling benefits of ventilating […]
Insulating ceilings is one of the most cost-effective energy efficiency measures. In addition to reducing heat loss in the winter and heat gains in the summer, ceiling insulation improves comfort by bringing ceiling temperatures closer to room temperatures and providing an even temperature distribution through- out the house. When planning and managing ceiling insulation projects, […]
Part 2 of Cooling Your Home Naturally with Fans and Ventilation. Natural ventilation relies on the wind and the “chimney effect” to keep a home cool. Moving air ventilates your home by entering or leaving windows, depending on their orientation to the wind. When wind blows against your home, air is forced into your windows. […]
