Introduction
In 1965 the first set of Building Regulations were introduced, Building Regulations 1965. It was necessary to abide by these building standards during the carrying out of any building works. 1984 seen a substantial change with the introduction of the Building Act, this Act brought about fundamental changes to the Building Regulations and introduced functional performance standards which were supported by guidance set out in approved documents. The aim of this was to ensure that Building Regulations were strictly adhered to during the design and construction phase of any construction project, be it commercial or domestic.
October of 2012 brought about a change to the building regulations. These changes provided practical guidance with regards to the meeting of technical requirements of the Building Regulations. The technical booklets that were introduced gave advice on how to comply with the Building Regulations and also gave an allowance for alternative building methods to be used so long as they could be demonstrated to meet compliance. This meant that the regulations that were seen by many designers to be restrictive, were now less so.
Task 1
With the expansion of the construction industry, it is thought that the energy consumption of this sector, which currently counts for 40% of energy consumption in Europe, is likely to rise. Because of this legislation, these technical booklets were introduced with the intention of lowering CO2 emissions and energy consumption, and to promote use of renewable energy sources.
Technical Booklet F2 gives guidance on performance standards and design provisions in relation to specific aspects in the Building Regulations. Following the guidance set out in this Technical Booklet it is assumed that compliance with the requirements have been met. However this compliance can be overturned so “Simply following the guidance does not guarantee compliance” (Technical Bookle F2: 2012, page 3) This is due to the fact that the guidance contained in the technical booklet relates only to Regulations 39, 40, 41, 42, 43 and 47. Any works carried out must also comply with all other relevant Building Regulations, which include, but are not limited to, The Workplace (Health, Safety and Welfare) Regulations (Northern Ireland) 1993. These regulations must also be adhered to as they my impact the building design.
With regards to Energy Performance of Building however:

Task 2
Building regulations (Northern Ireland) 2012, Technical booklet F2, conservation of fuel and power in buildings other than dwellings, it is used for guidance and is followed in order to achieve compliance, it relates to regulations: 39 (Conservation Measures), 40 (Target Carbon Dioxide Emission Rates), 41(Consequential Improvements), 42 (Change of Energy Status), 43 (Renovation of Thermal Elements) and 47 (Provision of information) of The Building Regulations (Northern Ireland) 2012, which came into effect on 31st October 2012. Although not mentioned, Regulations 44 (notice of air pressure test), 45 (notice off commissioning) and 46 (notice of emission rate) are also applicable, there is just no guidance available in this technical booklet as they are merely submissions to building control.
It does not however, take into account other requirements of building regulations which must be met during design and construction phases, such as Workplace (Health, Safety and Welfare) Regulations (Northern Ireland) 1993.
