MAINTENANCE & REFURBISHMENT


technology and precise management of systems to create an atmosphere that supports both wellbeing and comfort. Today’s homes are now designed to be


more energy efficient and airtight - using triple glazing, high levels of insulation and providing a more robust, sealed up building envelope to conserve energy. While this is good for reducing heating costs and cutting carbon emissions, it can significantly reduce natural airflow entering the building and have a profound effect on temperature. These properties might look fine, but in time, will begin to trap in moisture and harmful pollutants, causing discomfort and risk for residents. The moment we make one change to


improve the performance of a home, for example increase insulation to reduce heat loss, we often set off a chain reaction that will affect something else. That’s the challenge we’re facing with today’s homes – especially in renovation efforts. As we strive towards Net Zero by making our buildings tighter and more energy efficient, if we don’t properly consider how those changes interact with other systems, like ventilation, we will quickly end up with sick buildings that need further retrofit down the line. Solving the delicate balance between fuel conservation and ventilation, however, means more than simply opening a window. That’s why effective, mechanical solutions are increasingly essential in modern homes.


Smarter solutions for healthier homes


Our properties need to care for the people who use them, not work against them. A well-specified ventilation system, such as mechanical ventilation with heat recovery (MVHR) for example, ensures that fresh, filtered air is constantly supplied throughout the home. It


doesn’t just bring in air from outside, it also helps manage humidity, extract stale air, and recovers 96% of valuable heat from the extracted air, feeding it back into the building to reduce heating demands. In homes with modern low-temperature heating systems, as now required under building regulations Part L, these types of ventilation systems play a key supporting role. Radiators operating at lower flow temperatures are more efficient when paired with MVHR systems that help maintain a stable indoor climate, meaning less strain on the heating system overall.


And the benefits go beyond just warmth. An MVHR system also offers a summer bypass function, allowing cooler air in without heat recovery when needed as well as adjusting humidity to balance drier air. This keeps rooms feeling fresh and pleasant in warmer months without relying on high-energy cooling systems.


This is IEQ in practice. Truly comfortable, healthy homes don’t just happen by accident. When lighting, acoustics, IAQ and thermal comfort are all aligned, the result is a space that feels calm, consistent and comfortable, without sudden spikes in temperature or suffocating air quality. To achieve this, it requires thoughtful planning and coordination from the very beginning of the building’s design. The impacts of IEQ are hard to ignore. People can sense when a space doesn’t perform at its best, even if they don’t know exactly why. A room that’s stuffy, noisy, or poorly lit effects more than just comfort, it can impact how we think, feel and perform.


As an industry, it’s time to shift the conversation beyond IAQ and other individual silos and begin thinking about truly integrated systems - a functioning individual product simply isn’t good enough.
