COMMUNITY INTEREST COMPANY
Home Energy Reduction CIC:
Aims and objectives
Home Energy Reduction CIC aspires to reduce energy use and fuel poverty in UK homes, and the impact of buildings on the natural environment through their carbon impact. Individuals, communities and businesses will benefit from a direct approach to educate and deliver hands-on guidance for substantial energy savings, thereby reducing fuel poverty.
Who we are
Diane Hubbard is passionate about the need to understand our existing dwellings and the importance of understanding air tightness whatever the age of the building.
From an academic research base in pre-1900 buildings, she has spent more than 15 years working in practical building physics consultancy – testing a wide range of buildings (from colleges to cottages and castles) and understanding the roles of moisture, infiltration and deliberate ventilation.
Diane’s practical work with her consultancy Green Footsteps has helped her identify a key gap in the retrofit process – the importance of baselining a building pre-retrofit.
To address this issue, she has written and delivers the Home Energy Doctor Baselining Buildings course (NOCN accredited), providing the practical training to enable existing building professionals to baseline buildings pre-retrofit using air tightness testing equipment and thermography.
In 2025, Diane was part of a group who established Home Energy Reduction CIC to work with third sector organisations, with the aim of reducing the retrofit performance gap on existing projects through the delivery of Baselining Buildings training.
Academic research area – airtightness and moisture in pre-1900 dwellings.
