RTRFIT is a Passivhaus design and retrofit consultancy with in-house air-tightness testing capability.  Our aim is to improve the comfort and energy efficiency of existing buildings for the benefit of occupiers and reduction of carbon emissions.  

We provide accurate energy analysis of the existing systems and fabric of buildings as a basis to plan implementation of energy efficiency measures and then coordinate the retrofit project including design and installation of MVHR, insulation, airtightness measures and windows with baseline, interim and completion air tightness testing.
