solutions for more sustainable homes Ruth MacEachern, Product Manager at EnviroVent, looks at the importance of choosing
The need for energy efficiency throughout a new build or refurbishment has never been more important. Recent advances in ventilation systems means not only should they be selected for their ability to enhance indoor air quality but energy efficiency is also a key consideration. Understanding energy-efficient ventilation Ventilation systems are designed to regulate airflow within a building, ensuring optimal temperature and humidity levels, which is particularly crucial in new homes built to modern airtightness standards. While airtight homes are great for reducing heat loss, this can lead to issues with condensation and mould growth if not properly managed, therefore selecting the right ventilation system is essential for maintaining good indoor air quality. How does ventilation optimise energy efficiency? An effective ventilation system can help to reduce energy consumption by optimising airflow, therefore lowering the demand for heating and cooling, which can in turn lead to reduced energy bills.
When considering ventilation solutions for new builds
or renovations, there are several systems to choose from, each with its unique benefits and applications. Mechanical Ventilation with Heat Recovery (MVHR) Mechanical Ventilation with Heat Recovery (MVHR) systems are whole house solutions that continuously extract stale, moisture- laden air from wet rooms and supply fresh, filtered air to living areas. These systems include a heat exchanger that recovers a high percentage of heat (up to 93% thermal efficiency in some models), which significantly improves energy efficiency. When seeking energy efficient ventilation systems, housebuilders must also achieve compliance with Approved Document O of the Building Regulations, which focuses on mitigating overheating in homes. Look for MVHR units that feature an automatic summer bypass function that diverts air around the heat cell during warmer
