Radiant barriers are more effective in hot climates than in cooler/cold climates (especially when cooling air ducts are located in the attic). When the sun heats a roof, it's primarily the sun's radiant energy that makes the roof hot. Much of this heat travels by conduction through the roofing materials to the attic side of the roof.
Pros and Cons of Metal Roofs Metal Roof Pros: Long lifespan. On-trend designs. Potential energy savings. Low-maintenance. Metal Roof Cons: More expensive to install.
The albedo of several types of roofs (lower values means higher temperatures). Reflective surfaces, or ground-based albedo modification (GBAM), is a solar radiation management method of enhancing Earth's albedo (the ability to reflect the visible, infrared, and ultraviolet wavelengths of the Sun, reducing heat transfer to the surface).
A warm roof is a roof that is not ventilated, [9] where the insulation is placed in line with the roof pitch. [10] A hot roof is a roof designed not to have any ventilation and has enough air-impermeable insulation in contact with the sheathing to prevent condensation [11] such as when spray foam insulation is applied directly to the under-side ...

A deep energy retrofit (DER) is an energy conservation project in an existing building that leads to an overall improvement in building performance.While there is no exact definition for a deep energy retrofit, it can be characterized as a whole-building analysis and construction process that aims to reduce on-site energy use by 50% or more using existing technologies, materials and ...
Cons: Time zone, weather. Santiago Bernabeu Stadium, Madrid. Pros: Home of Real Madrid soccer club, Bernabeu has a retractable roof, so no weather worries. Like Tottenham, there’s a retractable soccer field that makes way for an American football field underneath. In 2025, the stadium will host the NFL’s first-ever regular-season game in ...
