  2. Twinwall plastic - Wikipedia

    en.wikipedia.org/wiki/Twinwall_plastic

    Twin-wall polycarbonate is used most commonly for green houses, where it can support itself in a structurally sound configuration, limit the amount of UV light due to its nominal translucence, and can withstand the rigors of daily abuse in an outdoor environment. The stagnant air in the cellular space between sheets provides insulation, and ...

  3. Polycarbonate - Wikipedia

    en.wikipedia.org/wiki/Polycarbonate

    Polycarbonate is commonly used in eye protection, as well as in other projectile-resistant viewing and lighting applications that would normally indicate the use of glass, but require much higher impact-resistance. Polycarbonate lenses also protect the eye from UV light.

    Wall thicknesses should be similar to a thermal storage wall. If a water wall is used between the sunspace and living space, about 0.20 ft 2 of thermal mass wall surface per ft 2 of floor area being heated (0.2 m 2 per m 2 of floor area) is appropriate. In most climates, a ventilation system is required in summer months to prevent overheating.

  5. Passive daytime radiative cooling - Wikipedia

    en.wikipedia.org/wiki/Passive_daytime_radiative...

    Since silicon solar cells have a maximum efficiency of 33.7% (with the average commercial panel reaching around 20%), the majority of absorbed power produces excess heat and increases the operating temperature. [15] [76] Solar cell efficiency declines 0.4-0.5% for every 1 áµ’C increase in temperature. [15]

    The CIS Tower in Manchester, England was clad in PV panels at a cost of £5.5 million. It started feeding electricity to the National Grid in November 2005. The headquarters of Apple Inc., in California. The roof is covered with solar panels.

  7. Solar thermal collector - Wikipedia

    en.wikipedia.org/wiki/Solar_thermal_collector

    Space heating for residential and commercial applications can be done through the use of solar air heating panels. This configuration operates by drawing air from the building envelope or from the outdoor environment and passing it through the collector where the air warms via conduction from the absorber and is then supplied to the living or ...
