production of energy, this will help achieve the Scottish Government’s aim of reducing the amount of greenhouse gases being produced in Scotland and will help to combat the threat of global warming.
Key questions
Those undertaking the design, installation and commissioning of new or replacement building services should give careful thought to the level of energy efficiency required. Consideration of the age and
or other sources of heat loss, e.g. due to excessive openings and service penetrations. In new buildings such measures will normally be achieved by complying with the Building (Scotland) Regulations and the mandatory standards given in BSD technical handbooks specifically relating to energy conservation, i.e. Section 6.0 ‘Energy’. Standard 6.1 requires
that every building must be designed and constructed in such a way that: ● ● The energy performance is estimated in
accordance with a methodology of calculation approved under regulation 7(a) of the Energy Performance of Buildings (Scotland) Regulations 2008 ●●The energy performance of the building is capable of reducing CO2 emissions.
Compliance with this standard,
together with the other standards given specifically for lighting, heating and ventilation, should ensure that a new building and the services installed are energy efficient when a building is constructed.
Assessing performance Where work to install new services or replace or upgrade existing services in an existing building is being planned – e.g. the replacement of an existing electric heating system – the building’s energy efficiency level may not comply with the latest building standards. The first step should therefore be to assess if the proposed work is appropriate
Smart lighting is on the rise
condition of the building and the type of services to be installed should be considered, together with the following: ●●Is the building constructed to ensure energy efficiency and conserve energy? ●●Can renewable sources be used to reduce carbon emissions associated with energy production? ●●Is the equipment to be installed energy efficient? ● ●Are controls required to improve its equipment efficiency? On a basic level, there is no point
installing energy efficient equipment in a building that’s not been constructed to be energy efficient in the first place. As a minimum, the building envelope should be insulated to a suitable level and there should be no significant air infiltration
