With over 12 years experience in delivering quality Passivhaus training (previously under the CarbonLite banner), we relaunched in 2022 as Coaction Training CIC, an independent and not for profit organisation driving upskilling for low energy building in the construction industry.

The scale of the challenges presented by the climate emergency and social crises facing our society is overwhelming. We care deeply about finding ways to be part of the solution and we work tirelessly to deliver Passivhaus training that empowers designers, contractors, educators and wider stakeholders to drive positive change through the buildings they create.
