Retrofit & energy efficiency

Increasing the energy efficiency of our existing and future built environment.

Our retrofit and energy efficiency challenge.

Over half of the homes in the UK fail to meet a good level of energy efficiency. To solve this, our built environment needs to be retrofitted and built to reach a higher energy efficiency standards at a greater scale and pace than ever before if we are to meet our sustainability targets and access the social and economic benefits that retrofit can bring.

Scotland’s National Retrofit Centre

Scotland’s National Retrofit Centre, co-funded by the Scottish Government, Edinburgh Napier University, and BE-ST, will revolutionise our approach to retrofitting existing buildings. The SNRC is the first retrofit centre of Retrofit Scotland’s National Retrofit Network.

Launched in Jan 2024, we set on giving Scotland the retrofit centre it deserves. In April 2024, Edinburgh Napier University was awarded over £1.2M in grant funding from the Scottish Government’s Salix Public Sector Heat Decarbonisation Fund, to retrofit Scotland’s National Retrofit Centre.

Retrofit Scotland

Through the Retrofit Scotland programme, BE-ST provides training, community convening and consultancy for the retrofit community in Scotland to make retrofit possible at scale, and build a future where it is more affordable, reliable and accessible to everyone in Scotland.

Energy efficiency & Scottish Passivhaus equivalent

Making our buildings energy efficient means finding ways to reduce the amount of energy needed to heat or cool a building while improving comfort, performance, and overall quality.

BE-ST offers training, consultancy, and networking opportunities around Passivhaus and airtightness principles to help industry feel ready to meet future legislation and client needs.

Heat in buildings

Clean heat is no longer a future ambition. It’s a growing need.

Scotland’s declaration of a Climate Emergency and ambitious target to meet net zero emissions by 2045 has set the country on a path of transition to a decarbonised economy. This will lead to growth in a number of ‘clean’ industries, and provide opportunities across Scotland in many skilled roles.
