Retrofit specialist for old houses in the UK – whole house energy analysis & project planning.

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 retrofit specialist that is able to guide people who want to integrate high-performance energy efficiency into whole-house refurbishment & renovation. The approach used is holistic and robust, including everything from accurate energy analysis, modelling and costing up materials needed, to advising on building contractors and even providing project management when needed. Passive House methodology and thermal bridge modelling are used for the analysis – tools which are well known for their accuracy – which enables homeowners to reach specific space heating demand or carbon emissions reduction targets.

This had included not only the calculation of what strategies were appropriate to reduce heat loss, listing the materials required, their quantities and suppliers, but also co-ordination of the work and installing the MHVR.
