From 1st August 2007 EPC have been introduced for domestic properties with four or more bed rooms in England, after one year October 2008 it has been a legal obligation through commercial and public buildings must have one as a means to raising awareness about energy efficient practices and it becomes part of the law for every commercial property in the UK. Whenever a property built, sold, rented or leased EPC should be through available as soon as marketing commences. It has been focused to help improve energy efficiency of buildings. EPCs are twisted using industry-standard methods and work out about energy usage. As a result of this, the energy efficiency of one building can be compared with another building of the same type. This enables potential buyers, land lord, tenants, occupiers and purchasers to see information on the energy efficiency and carbon emissions from their building so they can think about energy efficiency and oil expenses as part of their venture. The EPC has to be made available at the earliest opportunity and no later than the earliest of, The commercial EPC will provide the energy rating of a building, enabling the customer or tenant to make an informed decision as to the energy efficiency of their investment. These commercial EPC papers rate a building’s power efficiency from grade A to G, taking into account factors such as the equipment used during the building construction process and the amount of insulation in the land. The commercial EPC also comes with a list of recommendations, detailing ways in which owners can improve the energy efficiency of their buildings – thereby helping them to save money, as well as the batter environment. Now a day’s global warming is big issue around the world, For our behavior global warming is the continued rise of the earth’s temperature, and Greenhouse gases are one of the main contributing factors to the continued threat of global warming. Energy improvement measures can have as an outcome significant savings and they can reduce global warming. This is why the EPC is essential batter environment for our and next generation, not only for commercial buildings but also for all house owners.
