Solar Heat Gain
This process happens when sunlight strikes an object and turns into heat.
Solar heat gain
What are the three methods of thermal heat loss?
Infiltration, ventilation, transmission.
What is moisture in buildings?
Water in small amounts is found in air, substances, or surfaces.
This coefficient measures how much solar radiation passes through a window.
Solar Heat Gain Coefficient (SHGC)
What are the 3 things transmission is composed of?
Conduction, convection, and radiation.
What is moisture from the ground to the walls called?
Rising damp.
Name one envelope material that increases solar heat gain
Metal veneer (Also: asphalt roofing, darker colors)
What does insulation do to prevent heat loss?
It separates air into tiny volumes and reduces convection.
What is moisture intrusion?
Unwanted water entering the building's interior.
Why does asphalt absorb more heat than concrete despite lower thermal conductivity?
What is its darker color and lower reflectivity
Name two types of insulation materials.
Spray foam and mineral wool.
Name the most common cause of moisture intrusion.
Rainwater infiltrating through leaks.
Name two strategies to reduce solar heat gain in hot climates.
brighter roofing materials and increased insulation (Also: green roofs, less conductive veneers)
What is the formula to convert RSI to R-Value?
Multiply RSI by 5.678.
How can vapor retarders help control moisture?
They act as barriers to vapor.
