It has been assumed that accredited construction details have not been used but the property will have 100% draught proofing. Construction 5. Timber Frame construction achieving a U value of 0.23 w/m 2 k as per the Glidevale U value calculation provided mm of Kingspan TP10 has been assumed between the trusses (at 600mm centres) with a continuous 20mm layer of Kingspan TP10 the underside to achieve a U value of 0.17 w/m 2 k. 7. It has been assumed that the sloping ceiling insulation is continuous from eaves to ridge mm of Celotex GA4000 has been assumed as insulation for the floor. 9. The windows have been assumed to have a U value of 1.6 w/m 2 k. You should check this figure with the supplier and notify MSBC if a different value is achieved.

7 10. The solid and ½ glazed doors have been assumed to have a U value of 1.8 w/m 2 k. You should check this figure with the supplier and notify MSBC if a different value is achieved. Ventilation Extractor fans have been specified. 12. It has been assumed that the windows will provide the rapid ventilation for the rooms and there will not be a heat recovery or other similar system for ventilation. Heating 13. A 90% Efficient mains gas condensing combi boiler has been specified as the main heating source. The following have been assumed:- a. On / off burner control as opposed to modulating b. Delayed start stat c. Time and Temperature Zonal control to the radiators d. No Compensator e. Flue type unkown with no fan assistance f. No external pump. 14. You are strongly advised to check that natural gas is available. Use of LPG/Oil/Electric instead will affect the result and is may result in a fail on the calculation. 15. Zonal control will be required to the radiators. 16. Heating assumed to be by radiators and not under floor. You are advised to discuss the above with your heating contractor prior to installing the system and advise us of any changes that are proposed to ensure that compliance with the Building Regulations is still achieved.

It is based on the energy costs associated with space heating, water heating, ventilation and lighting less cost savings from energy generation technologies. It is adjusted for floor area so that it is essentially independent of dwelling size for a given built form. The SAP rating is expressed on a scale of 1 to 100, the higher the number the lower the running costs. EI RATING This is the Environmental Impact rating for your house. It is based on the annual Co2 emissions associated with space heating, water heating, ventilation and lighting, less the emissions saved by energy generation technologies. It is adjusted for floor area so that it is essentially independent of dwelling size for a given built form. The EI rating is expressed on a scale of 1 to 100 +, the higher the number the better the standard. CO2 EMISSIONS This represents the Carbon Dioxide emissions from your dwelling expressed in tonnes per year. TER This is the Target Emission Rate for Co2 from your dwelling expressed as kg of CO2 per square meter of floor area. DER This is the calculated Co2 from your dwelling expressed as kg of Co2 per square meter of floor area and must NOT exceed the TER otherwise your dwelling will not meet the requirements of the Building Regulations. ENERGY COST This gives a comparative heating cost based on a standard occupancy, heating patterns and geographical locations. Due to changes in fuel cost it will only be relevant at the time the calculation was undertaken and will depend upon the occupiers use of the heating and hot water systems. Actual fuel costs are therefore likely to differ from this figure. Ene1 Credits (Code for Sustainable Homes) Based upon the percentage reduction of DER/TER Ene2 Credits (Code for Sustainable Homes) Based upon the Fabric Energy Efficiency Ene7 Credits (Code for Sustainable Homes) Based upon the percentage emission reduction achieved by renewable technologies CfSH level The mandatory level achievement by reference to ENE1 and ENE2 categories. NOTE though that are numerous other issues that need to be achieved to achieve a Code rating and this is only one indicator. For more information go to
