6. Building Standards and Historic Scotland have shared interests in the sustainable management of the built environment and have worked together on projects such as "Guide for Practitioners 6 - Conversion of Traditional Buildings, Application of the Scottish Building Standards".
7. Listed buildings are buildings of special architectural or historic interest, and conservation areas are areas of special architectural or historic interest the character of which it is desirable to preserve or enhance, both designated under the Planning (Listed Buildings and Conservation Areas) (Scotland) Act 1997.

10. An Asset Rating is a calculated rating based on standard weather data and building use. It is similar in principle to "typical use" consumption figures for cars and is useful when comparing two buildings with different users, i.e. provides like-for-like figures. This is not only useful for potential owners and occupiers of buildings, but also has the ability to drive those who invest in buildings, the building owners, to spend money on carbon reducing fabric and services.
11. An Operational Rating is based on measured energy use. It takes account of how the building is used and managed and is useful for energy managers of the building because it includes factors they control. It has the scope to drive those who manage buildings to deliver carbon savings from the equipment already installed.
12. Further details on EPCs can be found on the Building Standards Division website at: http://www.sbsa.gov.uk/epc.htm
13. Cost effectiveness has been defined in terms of simple payback; a typical payback period of 4 years has been applied to this option.
14. These energy savings are based on the known potential for energy savings across the UK stock of existing buildings which relates to improvement to the building envelope and to the heating, lighting and cooling systems, i.e. the areas/aspects of energy consumption that are addressed by EPCs.
15. This is in line with the RIA in support of implementing EPCs in England and Wales.
16. "Reducing carbon emissions from commercial and public sector buildings in the UK". BRE Report for DEFRA, ref CR 211 104, 2005.
17. The typical payback time is likely to be longer as it will require measures which are close to the cost effective limit in addition to measures which have shorter payback periods and which are more likely to be taken up voluntarily.
18. This covers public and commercial sector organisations with half hourly metering and an annual energy consumption of over 30,000 GWh.
19. BRE estimate.
20. These additional savings are assumed to come from improved operational practices and from the use of more efficient energy using equipment such as computers and printers.
21. In practice the persistence will vary depending on the mix of measures implemented, but such detailed analysis is beyond the scope of this strategic study and so this figure has been chosen to represent a mix of long term measures (e.g. fabric insulation) and more short term measures (e.g. more efficient lamps).
