EnerPHit
EnerPHit is the Retrofit certification scheme from the Passivhaus Institute. It is very prescriptive about energy use and airtightness, but consistently delivers the highest performance and lowest running costs. EnerPHit is independently certified.
The Retrofit Opportunities Plan is a professional home survey from an independent and qualified Architect and Retrofit Coordinator that introduces you to a range of options to improve the energy efficiency of your home.
Chapter 2 Architects will visit your home and help diagnose any problem areas around heat loss, draughts and lack of comfort in winter or summer. You can also discuss any short-term plans for remodelling or extending, and how this might impact on energy efficiency. During the winter months the survey also includes thermographic imaging as standard. You’ll receive a bespoke report with helpful diagrams and images based on the findings.
The Retrofit Opportunities Plan runs through each measure in turn ranging from quick DIY actions to adding insulation, upgrading your heating system or adding renewable technologies. You’ll gather greater insight into how your home currently performs along with easy wins, short-term and long-term steps to Reduce energy, increase comfort and save money.
“I would definitely recommend engaging Alex in a project as early as you can so you can include energy saving principles in your project from the outset. He obviously really cares about what he’s doing and goes the extra mile to help.”
Feedback from recent Retrofit customers:
“Alex was clear, helpful and very good value for the consultation. We received an excellent report very quickly.”
“Just gone over the report tonight with my highlighter pen, great stuff and really helpful in pointing out what are actually realistic options.”
“An extremely worthwhile exercise and a real eye-opener for assessing current performance and future improvements for our house.”
“The report will help us to save money in future by directing us to the most cost-effective improvements and also by guiding us in terms of dependencies between jobs. It has also drawn our attention to things that we hadn’t really considered before.”

What is Retrofit?
Retrofit is the process of making improvements to a building that increases the comfort of occupants, cuts the energy demands (& bills) and reduces carbon emissions. For the UK climate, heating our buildings uses the most energy, whether it be supplied by gas, oil or electricity. Retrofitting focuses on reducing the space heating demand by increasing the insulation value of the building fabric (walls, floors, roof and windows). Therefore you need less energy to heat your property, and the money you do spend on energy doesn’t leak away so easily. Internal temperatures are more stable and comfortable. When combined with a suitable ventilation strategy, you’ll create a healthy internal environment and avoid condensation on internal surfaces.
Once you’ve taken this ‘fabric first’ approach, renewable energy sources can be considered like roof mounted PVs and heat pumps to make your home free of fossil fuels. If you are considering renovating or extending, installing Retrofit measures at the same time delivers a more efficient package and avoids future disruption.
At Chapter 2 Architects we aim to get as many people started on their Retrofit journey as possible, demystifying the terminology and making the solutions more relatable. A full Retrofit may take 10-20 years in multiple carefully planned phases. Start learning about Retrofit now and take your first steps to improve your home, reaping the joint benefits of greater comfort and lower bills.
-
Finding opportunities to increase the insulation of elements forming the building fabric
Improving the air tightness (= less heat loss) alongside an appropriate ventilation strategy
Reducing the space heating demand (typically from mains gas)
Upgrading old building plant (e.g. boilers, cylinders and controls)
Moving away from fossil fuels for heating and hot water demands
Lowering fuel bills, reducing fuel poverty
Improving indoor air quality (temperature, humidity, CO2 etc.)
Introducing renewable energy sources to respond to the new, lower energy demands of the building
-
A ‘shallow’ Retrofit seeks to reduce energy use by up to 30% by tackling the easy wins and less disruptive works. A ‘deep’ Retrofit targets 60% reduction in energy use, which involves greater cost and complexity. Renewable energy should be considered after the fabric, so the PV or Heat Pump is optimised to meet the lower energy demand. Retrofit works can be phases to suit your circumstances.
PAS 2035 is a government standard for Retrofit Coordination and Risk Management, designed to protect the homeowner and deliver the improvements promised by the design. Changing the way your home deals with moisture and heat loss could create condensation problems if the elements do not properly interact. Therefore it is important to avoid unintended consequences. The PAS 2035 process is compatible with a number of certification schemes like the Passivhaus Institute’s EnerPHit standard or AECB’s CarbonLite.
Employing a professional Retrofit Coordinator will ensure that early phases do not limit the options in the future. If you want to start planning your retrofit journey, please get in contact.

We can help establish budget costs for each energy saving measure, or package of measures installed together. Most measures will have a payback period. Any upfront costs must be considered against the long-term savings and carbon reduction.
