Who Should Take This Course?

This course is suitable for building services designers and consultants responsible for ventilation system design, architects and specifiers looking to incorporate MVHR in commercial projects, facilities and property managers considering MVHR retrofits, installers and contractors planning MVHR installations, and anyone involved in the design, specification, or installation of ventilation systems in commercial buildings.

Why MVHR Matters in Commercial Buildings

Mechanical ventilation with heat recovery provides fresh air while recovering heat that would otherwise be lost through ventilation. In commercial buildings, where ventilation rates are higher and energy costs are significant, MVHR can deliver substantial energy savings while maintaining good indoor air quality.

Understanding how MVHR systems work, the different types of heat exchangers available, and where MVHR is most effective helps building services professionals design efficient, compliant ventilation systems that support both occupant wellbeing and energy performance targets.

Frequently Asked Questions

What is Mechanical Ventilation with Heat Recovery (MVHR)?
Mechanical Ventilation with Heat Recovery is a ventilation system that supplies fresh outdoor air to a building while extracting stale indoor air. The system recovers heat from the outgoing air and transfers it to the incoming air, improving energy efficiency while maintaining good indoor air quality.

Why is ventilation important in commercial buildings?
Ventilation removes pollutants, moisture, and excess heat from indoor spaces while supplying fresh air to occupants. In commercial buildings with high occupancy levels, effective ventilation is essential for maintaining healthy indoor air quality, comfort, and compliance with building regulations.

How does an MVHR system recover heat?
MVHR systems use a heat exchanger to transfer thermal energy from the warm air being extracted from the building to the cooler incoming fresh air. This process helps retain heat that would otherwise be lost, reducing heating demand and improving overall energy efficiency.

Where are MVHR systems commonly used?
MVHR systems are used in a wide range of commercial environments including offices, schools, hotels, healthcare facilities, and residential developments. They are particularly beneficial in energy-efficient buildings where controlled ventilation and heat recovery are important.

What types of heat exchangers are used in MVHR systems?
Common types of heat exchangers include plate heat exchangers, rotary heat exchangers, and counterflow heat exchangers. Each type offers different performance characteristics in terms of efficiency, moisture transfer, and suitability for specific building applications.

What legislation affects ventilation systems in the UK?
Ventilation systems in the UK are influenced by regulations such as Building Regulations Part F, which sets minimum ventilation requirements. Energy efficiency considerations may also relate to Part L and other industry guidance such as CIBSE standards.

What are the main benefits of MVHR in commercial applications?
MVHR systems improve indoor air quality while reducing energy consumption by recovering heat from extracted air. They can support sustainability targets, reduce heating loads, and provide consistent ventilation for occupant comfort.

Is this course suitable for professionals new to MVHR?
Yes. The course provides a clear introduction to MVHR principles, applications, and regulatory considerations, making it suitable for both newcomers and experienced professionals looking to deepen their understanding of ventilation systems.
