Discover the Power of Passive House & EnerPHit Retrofits
Understand the Difference & See What’s Possible for Your Home
The Passive House Standard is the best for energy efficiency. It helps buildings use minimal energy and stay comfortable inside.
For existing buildings, we call this standard EnerPHit.
At Kore Retrofit, we specialise in EnerPHit projects, bringing buildings as close as possible to Passive House performance.
If you're researching Passive House or EnerPHit, you're probably looking for:
A home that’s warm in winter and cool in summer—without high energy bills.
A healthier indoor environment with fresh, filtered air.
A sustainable, future-proofed home that uses a fraction of the energy of a standard house.
Passive House vs. EnerPHit – Which One Do You Need?
-
Building a New Home?
Passive House is the gold standard. The most energy-efficient way to build from the ground up uses up to 90% less energy for heating and cooling.
-
Retrofitting an Existing Home?
EnerPHit is the Passive House standard for existing buildings. It works with your home’s current structure while still delivering incredible energy savings, comfort, and air quality.
We Believe in EnerPHit: The Future of Passive House Retrofit
At Kore Retrofit, we offer a complete solution for deep energy retrofits. Our goal is to help homes achieve great comfort, save energy, and improve indoor air quality.
Our Managing Director, Dr. Barry McCarron, knows the benefits of high-performance retrofitting. He turned his 1970s bungalow into an award-winning Passive House.
Barry’s home shows this idea well. It creates a high-performance, healthy, and comfortable living space. Best of all, it costs about the same as a cappuccino each day!
What to Expect From an EnerPHit Retrofit
-
Super-Insulated Walls, Floors & Roof
EnerPHit upgrades focus on superior insulation, significantly reducing heat loss. Upgrading walls, floors, and roofs with materials like EPS insulation helps homes stay at a stable temperature. This also lowers energy costs.
-
Triple-Glazed Windows & Doors
Enhanced glazing improves thermal efficiency and minimises heat transfer. EnerPHit-certified triple-glazed windows and doors stop drafts and cut down noise. They assist in making your home cosier and energy-saving.
-
Airtight Construction
Airtight building design eliminates air leaks, ensuring maximum efficiency in heating and cooling. By sealing gaps and using advanced air barriers, EnerPHit retrofits enhance indoor comfort while reducing energy demand.
-
Mechanical Ventilation with Heat Recovery
MVHR Systems keep providing fresh, filtered air while recovering heat from outgoing air. This improves indoor air quality, prevents condensation and mould, and maximises energy efficiency in a tightly sealed home.
Is EnerPHit Right for Your Home?
My home is built, and I want to reduce energy use by 90%.
I want to stop relying on fossil fuels for heating and cooling.
I’m looking for a high-performance home upgrade, not just basic insulation.
If this sounds like you, you’re in the right place.
