The range of application of SF₆ Gas Insulated Switchgear extends from voltage ratings of 72.5 kV up to 800 kV with breaking currents of up to 63 kA‚ and in special cases up to 80 kA. Both small transformer substations and large load- centre substations can be designed with GIS technology. The distinctive advantages of SF₆ Gas Insulated Switchgear are: compact‚ low weight‚ high reliability

Structural insulated panels SIPs The principal of sustainable building based on efficiency. The concepts of efficiency are paramount to the understanding the practice of building and the application of choosing framing types based on the most desirable outcomes. Regardless of the external environment the practice of building revolves around the acceptability of the interior environment of the building to the occupants and objects therein contained. The pursuit of constructing energy efficient buildings

Because the garage is nevertheless a part of the house; it is important to have the door insulated against the wind‚ rain‚ snow and other elements in order to keep utility bills under control. Some of the insulated garage doors come with a bottom weather strip which not only helps to keep weather out‚ but also work together with the doors overall insulation to keep noises of the street from entering your home. Insulated garage doors are usually built of durable and heavy duty insulation such as polyurethane

For a business to be seen using sustainable construction techniques like the use of solar panels it will give them a good public image and people will be more inclined to use them for their service. Materials – SIPs or Structural Insulated Panels are a good sustainable construction technique. SIPs are large panels that when all fitted together make a house. They are pre-fabricated off site to exact measurements so everything slots together perfectly. When they are brought onto site

Sea and Land Breeze A sea breeze describes a wind that blows from the ocean inland towards land. This breeze occurs most often in the spring and summer months because of the greater temperature differences between the ocean and nearby land‚ particularly in the afternoon when the land is at maximum heating from the sun. During the day‚ the sun heats up both the ocean surface and the land. Water is a good absorber of the energy from the sun. The land absorbs much of the sun’s energy as well. However

heat escapes from the house‚ it costs money and wastes resources. In deciding how cost-effective an energy-saving measure is‚ we need to know what its pay-back time is. In other words‚ taking the example of double-glazing: how long will it take before the cost of having the double-glazing installed will be recovered by what we save in fuel bills? The calculation is: pay-back time in years = cost of energy-saving measure ÷ money saved each year http://www.frankswebspace.org.uk/ScienceAndMaths/physics/physicsGCSE/reduceHeatLoss

In passive solar technique‚ glazing plays a vital role in absorption‚ transmission and distribution of solar radiations‚ moreover placing large windows in south side it increases the absorption of solar radiation‚ which will be essential during winter. The radiation getting in through the glazing is absorbed by concrete or masonry walls‚ stone floor slabs etc. These materials help in increasing absorption‚ density
