Graham has commenced the journey towards the widespread adoption and implementation of the Passivhaus standard and methodology

Developed by the German Passivhaus Institute, the standard can be achieved through the adoption of a number of factors including “Passive Design Principles” and a “Fabric First” approach, which includes enhanced levels of insulation, reduced thermal bridges and stringent air-tightness requirements.

Its primary purpose is to achieve a high level of indoor comfort and health while using little heating, cooling and total energy.

Passivhaus buildings can deliver up to a 90% reduction in space heating requirements when compared to traditionally constructed buildings.

As well as for new buildings, the Passivhaus approach can also be used for refurbishment projects via the EnerPhit Certification Process.

Graham have committed to a zero-carbon emissions target by 2045 and a 30% reduction in our carbon intensity.

A ‘real step-change for the construction industry’

Craig Bridges, Graham strategic business director, said: “We are committed to implementing and embedding the Passivhaus principles throughout Graham.

“The creation of a dedicated development group, and the recent graduation of James and George as certified passive house designers, are clear indicators of our proactive engagement with Passivhaus and demonstrate why we are recognised as a leading responsible, sustainable contractor.

“The Passivhaus Trust, a UK affiliate of the Passivhaus Institute, has recorded the development of over 1000 certified Passivhaus units in the UK. The implementation of the standard is growing at a considerable rate.

“At Graham, we understand the clear benefits that Passivhaus delivers in achieving significant energy and carbon reductions.

“Therefore, we are excited about the continued development of our in-house capabilities and are energised to leverage off the strategic partnerships which we have established to expand our expertise.”
