Energy efficiency in non-domestic buildings
There are approximately 200,000 non-domestic buildings in Scotland, and these vary widely in terms of construction, size, and in particular their use, whether it's as shops, offices, factories, warehouses, or hotels.
The diverse nature of non-domestic buildings means we know less about their energy performance compared with those in the domestic sector. As of July 2017 there were around 30,000 non-domestic buildings with an EPC assessment.
Given the wide variety of building size and use in the non-domestic sector, we proposed to move to a benchmarking system for assessing energy efficiency and are seeking views on this in the Energy Efficient Scotland consultation.
We also proposed to build on the current Non-Domestic Energy Efficiency (NDEE) regulations under the Climate Change (Scotland) Act. These currently only apply to buildings over 1,000m2, and buildings can defer improvement by reporting their energy use. By 2040 we aim to have extended the regulations to all non-domestic buildings, and for them to be improved to the extent that this is technically feasible and cost effective. We will phase in the regulations so that they are extended to progressively smaller buildings over time.
We will consult further on our plans for the non-domestic sector in 2019 and set out our proposals for this sector by 2020, ahead of new regulations commencing in 2021. Our proposals will focus on our advice and support services, as well as Resource Efficient Scotland, Local Energy Scotland, and the public-sector NDEE Project Support Unit, who together provide advice and project support to small to medium enterprises (SMEs), communities, and public sector organisations.
We have produced the following guide on improving energy efficiency within SMEs: Energy Efficient Scotland user guide: small and medium enterprises
Alignment with industrial energy
We are also committing to work with industry on the energy efficiency of non-domestic buildings. We will align our offers of advice and support to consider energy use in its entirety, recognising that reducing the energy used for manufacturing can be as important as ensuring the energy efficiency of the building.
