ColdProof

About us

Tired of living in an uncomfortable house? If you are planning to carry out any significant renovation or retrofit of your house, it will provide you with an ideal opportunity to address any chronic issues common to older houses, such as heat loss in colder months and overheating in summer, discomfort from draughts, condensation and mould, health problems related to poor indoor air quality, and huge energy bills.

ColdProof is a Certified Passivhaus Consultant conversant with PHPP design, specialising in retrofit projects. The main area of work is energy efficiency master planning, which involves detailed baseline energy analysis using Passive House methodology and thermal bridge modelling, followed by an action plan of improvements that enables individual homeowners to plan towards specific space heating demand targets. The plan is not only about the energy analysis that we do ourselves, but also involves coordinating with other specialists as needed in order to progress the planning (e.g. for MVHR design, hot water / heating / renewables design, structural analysis, window & door schedules, and moisture modelling).

In addition, ColdProof is involved in running training in low energy building techniques for retrofit and new build. This is mostly done with Coaction, a group of trainers that is running the Passivhaus Tradesperson course - this course has been running since 2018, the material for which we helped to develop. We also do one-on-one retrofit training and mentoring, as well as on-site training on request.
