The latest Technical Handbooks for Energy, both domestic and non-domestic came into effect on the 1st October 2015.
The Scottish Government has set the intention of Section 6 to ensure that effective measures for the conservation of fuel and power are incorporated into buildings.
The biggest change in this regulation came in 2007 with the transition to a single methodology for assessing carbon dioxide emissions for both carbon and energy performance in new buildings.
Scotland published their Climate Change Act in 2009 which set an interim target of a 42% reduction in emissions by 2020 raising to 80% by 2050 when compared to 1990 emission levels.
The introduction of the 2015 revision to Section 6 has seen the following reduction in emissions CO² being required:
45% reduction in CO² emissions over 2007
21% reduction in CO² emissions over 2010
60% reduction in CO² emissions over 2007
43% reduction in CO² emissions over 2010
