Passivhaus is an energy performance standard focused on reducing the heating demand of buildings to such an extent that traditional heating systems are not required. Passive design principles are employed to ensure internal comfort levels are maximised through extremely low air permeability, excellent levels of insulation, minimal cold bridging and glazing designed to maximise useful solar gains.

Our energy consultants can advise on all aspects of passive design, from thermal bridging calculations through to detailed overheating risk assessments. Our early involvement in the design process ensures that all opportunities for maximising the energy efficiency of a building are undertaken. Achieving PassivHaus Standard requires meticulous attention to all details of the design and construction process, and we assist with this throughout.
