  2. Reflective surfaces (climate engineering) - Wikipedia

    en.wikipedia.org/wiki/Reflective_surfaces...

    The average daily summertime temperature of the black roof surface was 75 °C (167 °F), but once retrofitted with a white reflective surface, it measured 52 °C (126 °F). Without considering any tax benefits or other utility charges, annual energy expenditures were reduced by $7,200 or $0.07/square foot.(This figure is for energy charges as ...

  3. Building insulation material - Wikipedia

    en.wikipedia.org/wiki/Building_insulation_material

    Reflective insulation and radiant barriers reduce the radiation of heat to or from the surface of a material. Radiant barriers will reflect radiant energy . A radiant barrier by itself will not affect heat conducted through the material by direct contact or heat transferred by moist air rising or convection.

  4. Cool pavement - Wikipedia

    en.wikipedia.org/wiki/Cool_pavement

    Reflective pavement manufacturing involves the application of a top coat onto finished pavement, or the mixing of reflective materials into wet concrete. [4] Coating materials include water or solvent based coatings with high solar reflectance properties, infra-red colored coatings, and thermochromic materials [ 13 ] which change color and ...

  5. Radiant barrier - Wikipedia

    en.wikipedia.org/wiki/Radiant_barrier

    Reflective bubble/foil insulations are primarily radiant barriers, and reflective insulation systems work by reducing radiant heat gain. To be effective, the reflective surface must face an air space; also, dust accumulation on the reflective surface will reduce its reflective capability.

  6. Low emissivity - Wikipedia

    en.wikipedia.org/wiki/Low_emissivity

    Low emissivity (low e or low thermal emissivity) refers to a surface condition that emits low levels of radiant thermal (heat) energy. All materials absorb, reflect, and emit radiant energy according to Planck's law but here, the primary concern is a special wavelength interval of radiant energy, namely thermal radiation of materials.

  7. Emissivity - Wikipedia

    en.wikipedia.org/wiki/Emissivity

    Reflections (like on the blank end of the can and the countertop) make accurate measurements of reflective surfaces impossible. Temperature measurements Pyrometers and infrared cameras are instruments used to measure the temperature of an object by using its thermal radiation; no actual contact with the object is needed.

  8. Daylighting (architecture) - Wikipedia

    en.wikipedia.org/wiki/Daylighting_(architecture)

    Daylighting is the practice of placing windows, skylights, other openings, and reflective surfaces so that direct or indirect sunlight can provide effective internal lighting. Particular attention is given to daylighting while designing a building when the aim is to maximize visual comfort or to reduce energy use.

  9. Insulative paint - Wikipedia

    en.wikipedia.org/wiki/Insulative_paint

    A "thermal Image" or infra-red photograph will clearly show the reduction of winter time heat loss from a home through areas that have been painted with a true "insulative" or "insulating" paint. The ability to reflect or block heat from all sources such as fireplaces, heaters, and radiators inside a building as well as sunlight is the value of ...
