In 2012 the National Trust launched their Renewable Investment Energy Programme, committing over £30 million to halve their carbon emissions by 2020. CBG have worked with the Trust on at least 11 significant properties across the south of England. We have advised how the National Trust can utilise renewable energy sources to reduce these emissions.

The technologies we have considered include; biomass, solar PV, solar thermal, wind, combined heat and power, and heat pumps which can harness renewable energy from the ground, water or air.

Our feasibility assessment process includes detailed studies of the properties, liaising with staff and stakeholders, radiator surveys, load monitoring, and heat loss calculations, culminating in a comprehensive feasibility report that evolves to incorporate feedback from the Trust’s approval stages.

CBG have continued their project support through the tender process, providing tender return analysis and attending interviews. We undertake site visits throughout construction, as well as write inspection reports, and act as CDM Principal Designer.
