According to Regulation 3 Schedule 1 “A building used only by
people engaged in the construction, demolition or repair of any
building or structure during the course of that work” is exempted
from the building regulations. Exception is “ a building containing
sleeping accommodation.”
Hence, construction villages are not subject to
the Scottish Building Regulations as long as they do not include
sleeping accommodations.
There are no energy conservation provisions for the building
fabric and building services of transportable accommodation used in
construction villages. No attention is therefore paid to the energy
efficient design of such temporary accommodation.
