     Residents remain in-situ during the build

The Beattie Passive TCosy™ process results in minimal disruption for the resident. The system is easily constructed whilst the resident stays in their home for the duration of the project. Minimal disturbance when windows and doors are changed and the MVHR is incorporated.

     Transform your home from EPC F to A Rating

The innovative Beattie Passive TCosy™ can easily and cost effectively improve the EPC level of your property.

     Enhance the value of your property

An energy efficient home not only provides immediate dividends, through reduced energy costs, but also increases market value.​

     Improved comfort

Drafty rooms in winter? Hot rooms in summer? Retrofitting your home will increase the comfort of your entire home by addressing thermal bridges and poor insulation.

     Health benefits

Retrofitting existing homes to Beattie Passive standard reduces deaths and illnesses related to cold homes.

Installing MVHR within the TCosy™ frame improves health through enhanced ventilation and dramatically reduces the impact of Radon.

     Full design flexibility – any building, any shape:

Our design team will incorporate any house design, shape or style of architectural drawings into our 3D modelling system and deliver a custom made package incorporating all the key Passivhaus values of our TCosy™ system to you.

     Simple retrofit system

Our method of construction offers an easy to assemble frame-link retrofit system.

Due to the simplicity of the retrofit system it can be built by semi-skilled labour. Beattie Passive are passionate about developing skills in the industry and regularly work with colleges and skills development centres.

     75% reduction in heating requirements

Adding MVHR and quality windows to a Beattie Passive Retrofit structure reduces your heating requirements by up to 75%. The reduction of heating requirements helps lift people out of fuel poverty.

     CO2 emissions can be cut by as much as 100%

By using the Beattie Passive structure, MVHR and photovoltaic cells together you can achieve 100% reduction in CO2 emissions.

     Higher levels of thermal efficiency and air tightness

Existing Building Regulations | Beattie Passive
Thermal Efficiency/U-values: 0.28 | 0.12
Air tightness: 10 | 1 and below

     Fast on-site and off-site erection

The simplicity of the TCosy™ system allows for fast on-site erection. Beattie Passive TCosy™ is designed to be locally manufactured at any location using readily available materials and therefore does not have an extended lead-in time for procurement as a factory manufactured system.

     Minimal on-site material wastage

The use of our bespoke 3D modelling design allows all materials to be measured to within a 1mm, which greatly reduces on-site waste as well as over-ordering of materials.

     Sustainable materials from a fully certified supply chain

All materials used are from a fully certified supply chain.

     Easier inspection as all structural elements are open

All structural joints open to inspection.

Only one inspection to see all structural joints and fixing on completion of structural build.

Will not pass independent thermal and air tightness unless Retrofit is properly constructed and insulated.

Building control officers can study 3D drawings before arrival on site.

     Testing information

We inspect and independently performance test every Beattie Passive TCosy™ to ensure the highest standards of construction are maintained. We carry out stringent air tightness and thermal continuity imaging following structural completion and only upon reaching the design standard, will we issue a quality assurance certificate. We test at the right time, every time.

Thermal Modelling
"In terms of energy efficiency and living environment, many homes are no longer fit for purpose and look tired but remain occupied. TCosy is more cost effective and quicker than a re-build, avoiding the temporary re-location of residents. The updated contemporary look lifts and enhances the local environment."
