Tenders are invited for Providing and applying vitrified floor tiles and high albedo paint having minimum solar reflective index on floor and roof respectively in all the six night shelters under the assembly constituency-51 in connection with Construction of Night Shelter.
Countless solutions have been proposed, one of which, the installation of 'green' or 'cool' rooftops--using plants or high albedo surfaces to reduce solar absorption and mitigate the build-up of excess heat--appears to be increasingly gaining traction.
Estimating only direct component is usually enough when analysing solar thermal collectors, but PV modules also gain benefit from diffused and especially reflected radiation components when the surrounding environment has high albedo (e.
He said the NASA studies in the polar regions were based on expectations the regions are the places where early signal of a climate change can be found "because of ice-albedo feedback associated with the high albedo of ice and snow.
Environmentally responsible and energy-efficient design solutions, such as a high albedo roof, locally sourced materials, high-efficiency glass, building lighting controls, low-flow plumbing fixtures, and use of outside air through the rooftop HVAC units to cool water serving the main server room cooling system and energy recovery systems, were used to achieve LEED certification.
Therefore, to address this phenomenon, then among the mitigation strategy is to increase tree planting and apply the use of materials that have a high albedo to buildings, open space and roads surface [1][2][4][5][6].
Vesta is medium-gray, reflecting 42% of the sunlight striking it (a high albedo for an asteroid), whereas Ceres is a more typical dark gray-brown with an albedo of only 9%.
Highly reflective surfaces, such as ice, are said to have a high albedo, as they reflect most of the incoming heat back into space.
Asphalt-to-concrete conversions will continue to grow in parking lot specifications as owners measure lighting costs and high albedo ratings, and acknowledge concrete pavements' safety and economy.
Whereas the outdoor thermal comfort strategy include shading pedestrian connections through the provision of climate, controlled conditioned corridors, colonnades and the use of shading devices for the primary pedestrian routes, shading priority areas in the public realm including open spaces (public plazas), community parks, entrances to community facilities (including schools) and transit stops and reducing urban heat island effect through the use of high albedo (the fraction of Sun's radiation reflected from a surface) surfaces and a cool material palette.
In addition, the mix designs for the pervious portland cement concrete (PCC) would need to have high albedo (reflectivity) to minimize the urban heat island effect.
The longevity of this important polar feature, which contributes to keeping the climate cool by means of its high albedo, is in stark contrast to current predictions of the loss of summer sea-ice as early as ten years from now.
