Retrofitting is an absolutely essential element of the UK’s Net Zero strategy. At Beattie Passive, we deep retrofit to the rigorous EnerPHit standard. Here are the technical specifications of our patented TCosy™ deep retrofit system.
The Beattie Passive TCosy™ is a deep retrofit solution that creates a void, from foundations to roof, that encapsulates the existing roof and external brickwork. This is injected with insulation to a create a highly efficient building envelope, with no thermal bridges, that significantly enhances the U-value of the walls and roof.
|Floor||Perimeter U-value: 0.43w/m2k|
Insulated U-value: 0.13w/m2k
|Windows & Doors||Triple glazed, passive-certified U-value: 0.78w/m2k|
|Ventilation||High performance Mechanical Ventilation and Heat Recovery (MVHR). A full heat recovery ventilation system is installed with the new TCosy™ frame that recovers 84% of the heat from internal heating sources – supplying fresh, filtered air to all rooms. Incorporating the MVHR system within the frame, and penetrating only through the walls at high level, minimises internal disturbance and the loss of internal space.|
|Heating||Reduction in heating demand of up to 90%|
|Renewables||Photovoltaic panels (PVs) can be added to achieve Net Zero|

We inspect and independently performance test every Beattie Passive house to ensure the highest standards of construction are maintained.
We carry out stringent airtightness, thermal imaging and sound migration tests upon structural completion. We will only issue a quality assurance certificate if our stringent design standards have been met. We test at the right time, every time.
At Beattie Passive, we inspect and test each build for the following:
These tests are performed at crucial stages of the build process. Through these ongoing and stringent testing procedures, each Beattie Passive build achieves the highest standard of construction to meet the requirements for final certification.
For those building the system themselves, these test provides peace of mind that the building has been built correctly and ensures any minor defects can be rectified with minimal disruption and cost.
A full report showing all test results and statistics is supplied by Beattie Passive on completion. The report is stamped and signed to confirm all results are genuine and meet the standards required for Passivhaus certification.
