Insulation Inefficiency Strategy for improvement Attic
Draughts ?
• Insulate the attic with fibreglass or cellulose insulation to save heat from being lost through the roof
• Fit draught-excluders around windows and doors, as this can cut heat loss by as much as 20% in winter
• Install double- or triple-glazed windows
Identify three areas in the home where energy inefficiencies may occur and in relation to each suggest one method of improving efficiency. (18) OL
In relation to energy use in the home give details of potential energy inefficiencies and strategies for improvement. (18) HL
Building Energy Rating (BER) system
The Building Energy Rating (BER) system used for homes is similar to the energy label on appliances, with a scale of A to G. A-rated homes are the most energy efficient, while G-rated homes are the least efficient.
Since 1 January 2009, a BER certificate is compulsory for all homes being sold or rented and must be included in commercial advertisements. The home must be assessed by a registered BER assessor in order to determine a BER rating and obtain a certificate. During the survey they assess the:
• area of the rooms and windows • thickness of the walls and the levels of insulation
• heating system • floor and the wall types.
