The role of the buildings is emphasized for energy efficiency in and around the world. Because they are the most important energy consumer. It is not straightforward to ask the question that the energy usage of the building. Because energy usage varies according to the indoor conditions of the building. The building is very comfortable with the proper lighting, heating, ventilation, and cooling is depending upon the usage of the power. That is the consumption of energy for its comfort. The energy use intensity is confirmed with the flooring area of the building divided with the energy consumed. In this way, the energy efficiency of the building is measured. For the better energy consumption the consumer focus on the Energy Providers to get the reduction of energy rates. The energy consumption in a building is known to be particular or specific energy consumption (SEC) or energy use intensity (EUI).
Energy-efficient landscape: For energy consumption the usage of energy in the building that leads to the measures. Although the energy incorporation of the building materials is very much difficult in energy consumption. While the building is dismantled, the energy can be recovered from the materials by reusing the material or by burning the material. The indoor condition of the building varies in resulting in higher or in the lower quality when the building is used. By the use of the building finally, the overall efficiency of the power consumed is affected. The energy consumption is due to the occupation of the energy which or the building is occupied. The whole energy efficiency is calculated through the usage of the building like whether it is fully or partly occupied. It is more comprehensive to energy efficiency in buildings than trying to reduce energy consumption. The efficiency of the space use is most probably factored in and as well as the quality of the indoor environment is known to be the issues in energy efficiency. The passive measure of the landscape by its nature reduces the use of energy and its needs. Various functions of the measures help to improve the indoor conditions of the building and also reducing the energy use that increases the use of the natural light.
Utilization of energy: In regulating and illuminating the location and surroundings of the building plays an emphasized role. For an illustration, the hills, trees, landscaping helps to provide shade, and as well as it blocks the wind. The huge amount of sunlight enters the building is because of the southern hemisphere building with north-facing windows that minimizes the use of energy by increasing the passive solar heat. The heat loss was reduced by twenty-five to fifty percent while the tight building design with energy-efficient windows, tightly sealed doors, and basement slops, and additional thermal insulation of walls. Then the most reflective white space, dark roofs are 39 degrees Celsius hotter. The dark roof transmits more heat inside the building. The united state’s studies show that the lightly colored roof consumes forty percent less power than the dark sides of the roof building. In sunnier climates, the white roof saves more energy. The energy consumption has been moderated by the advanced electrical heating and cooling system.
