Have you ever heard the term “retrofit” but weren’t quite sure what it means? You’re not alone! Building retrofitting is a growing trend in the building industry, and it’s one that can benefit both homeowners and business owners. But what is retrofit, and why is it so important?
In this blog, you’ll learn:
- What retrofit is
- Why retrofit is important
- The benefits of retrofitting
- The different types of building retrofit
What is retrofit?
So, what is retrofit? In simple terms, a building retrofit is the process of modifying an existing building to improve its energy performance. This can encompass a wide range of upgrades, from insulation to solar panels. With many building constructed before modern energy efficiency standards were in place, retrofitting has emerged as a vital solution for bringing these structures up to today’s standards. As global energy demands rise and environmental concerns become more pressing, finding ways to make our existing buildings more energy-efficient has never been more crucial.
Why is building retrofit important?
Buildings are a major contributor to global energy consumption and carbon emissions. In fact, buildings are responsible for nearly 40% of global energy use and 36% of carbon emissions. Retrofitting existing buildings is a crucial strategy for reducing our environmental impact and achieving net zero emissions – a goal where we remove as much carbon dioxide from the atmosphere as we produce.
By making our buildings more energy-efficient, we can significantly reduce our reliance on fossil fuels and create a more sustainable future. Retrofitting is not just about cutting energy costs; it’s about playing a part in a larger effort to combat climate change.
What are the benefits?
Retrofitting your building offers a range of benefits for both your wallet and the environment. Here are some key advantages:
- Energy Savings: Retrofitting can significantly reduce your energy consumption, leading to lower bills and a smaller carbon footprint. Upgrading insulation, windows, and HVAC systems can decrease your energy use and translate to substantial cost savings.
- Improved Comfort: Upgrades like insulation and air sealing can create a more comfortable living or working environment by reducing leaks in the building envelope. This minimises air leakage, helps maintain consistent temperatures, and reduces drafts, which will ultimately lower your heating bills. Additionally, retrofits can address air quality concerns, creating a healthier living or working environment.
- Increased Property Value: Energy-efficient buildings often attract higher property values. Retrofitting your building demonstrates a commitment to sustainability and efficiency, which can be a major selling point for potential buyers or tenants. There are also financial incentives such as 0% VAT on measures like installing heat pumps, solar panels, and insulation.
- Sustainability: Building retrofit plays a crucial role in achieving environmental goals by minimising energy waste and reducing reliance on fossil fuels. By lowering energy consumption, retrofits can significantly reduce your building’s carbon footprint.

What are the types of building retrofit?
There are many different types of retrofits, each with its own specific goals. Here are a few examples:
- Energy Efficiency Upgrades: These upgrades focus on reducing energy consumption in a building. Examples include installing insulation, upgrading windows and doors, and replacing old HVAC systems with more efficient models. For instance, upgrading to double-glazed windows can reduce heat loss, while modern HVAC systems can improve energy efficiency by up to 30%.
- Water Conservation Measures: Retrofitting can also involve installing water-saving measures and appliances to reduce water usage in a building. Low-flow taps, dual-flush toilets, and water-efficient landscaping can all contribute to water savings.
- Renewable Energy Installations: Solar panels, heat pumps, and other renewable energy sources can be integrated into a building through retrofitting, reducing reliance on fossil fuels. Installing solar panels not only reduces reliance on the grid but can also lead to energy independence.
What’s next?
Retrofitting your building doesn’t just make it more efficient and comfortable; it’s also an investment in the future. By creating a more sustainable and environmentally friendly building, you’re saving money and also contributing to a greener planet.
