Why Ventilation Matters

A well-insulated home is great for retaining heat and reducing energy bills, but it can also trap moisture, pollutants, and stale air if proper ventilation isn’t considered. This can lead to condensation, mould growth, and poor indoor air quality—issues that negatively affect health. Ventilation ensures that while your home is warm and energy efficient, it remains free from damp and maintains high air quality.

The Impact on Health

Poor indoor air quality caused by inadequate ventilation can lead to a range of health problems, from respiratory issues like asthma to more serious long-term health conditions. Modern homes are often sealed tight to prevent heat loss, but without effective ventilation, these energy-efficient properties can create environments where harmful pollutants build up, including carbon dioxide, volatile organic compounds (VOCs), and allergens.

How PAS2035 Addresses Ventilation

PAS2035 highlights the importance of a “whole-house approach” to retrofit projects, meaning energy efficiency measures must be balanced with the right type of ventilation. This includes:

1. Assessing Ventilation Needs: Before any retrofit work begins, a ventilation assessment is conducted to identify current systems and determine what additional ventilation may be required.
2. Improving Airflow: If a home is to be heavily insulated, systems like trickle vents, mechanical ventilation with heat recovery (MVHR), or extractor fans may need to be installed to ensure a healthy airflow.
3. Monitoring and Maintenance: PAS2035 also emphasises the importance of ongoing monitoring to ensure that ventilation systems continue to work effectively after installation.

Benefits for Homeowners

When ventilation is done right, homeowners can enjoy several benefits:

• Better Health: Clean, fresh air reduces the risk of respiratory conditions and other health problems.
• Comfort: Proper airflow prevents stuffiness and helps control humidity levels, making homes more comfortable year-round.
• Energy Efficiency: Modern mechanical ventilation systems, like MVHR, can recover heat from outgoing air, improving overall energy efficiency.

Ventilation and Renewables

At GB Home Energy, we believe in a future where homes are both energy efficient and comfortable to live in. Whether it’s installing solar panels, heat pumps, or upgrading insulation, ventilation is a key part of any retrofit project. Following PAS2035 guidelines means we ensure that while reducing carbon emissions, we also create homes that are healthier and safer for everyone inside.

Conclusion

Ventilation is an often overlooked but essential part of making homes energy efficient. Under PAS2035, it’s a priority to ensure that UK homes are not only warmer and greener but also healthier places to live. If you’re considering a retrofit for your home, make sure ventilation is at the heart of the project.
