EN 16798 Performance Requirements

Energy performance of buildings is a measure of how efficiently a building uses energy to provide heating, cooling, ventilation, and other services. Ventilation is an important part of energy performance, as it helps to maintain a comfortable and healthy indoor environment.

Ventilation for non-residential buildings is covered by two modules of the European Standard on Energy Performance of Buildings (EPB): Module M5-1 and Module M5-4.

Module M5-1 provides guidance on the design and operation of ventilation systems for non-residential buildings. It covers the principles of ventilation, the different types of ventilation systems available, and the factors to consider when choosing a system. The module also provides guidance on the maintenance and testing of ventilation systems.

Module M5-4 provides performance requirements for ventilation and room-conditioning systems in non-residential buildings. It covers the minimum requirements for ventilation rates, air quality, and energy efficiency. The module also provides guidance on the design and operation of ventilation and room-conditioning systems to meet these requirements.

Here is a summary of the key performance requirements for ventilation and room-conditioning systems in non-residential buildings according to Module M5-4:

• Ventilation rates: Minimum ventilation rates are specified for different types of non-residential buildings and activities. For example, the minimum ventilation rate for an office building is 10 liters per second per person.
• Air quality: The air quality inside non-residential buildings must meet certain standards, such as limits on the concentrations of carbon dioxide, particulate matter, and other pollutants.
• Energy efficiency: Ventilation and room-conditioning systems must be designed and operated to minimize energy consumption. For example, heat recovery systems can be used to capture and reuse heat from exhaust air.

The specific performance requirements for a particular non-residential building will depend on its type, size, and location. However, the performance requirements in Module M5-4 provide a general framework for designing and operating energy-efficient ventilation and room-conditioning systems.

Here are some examples of how to meet the performance requirements for ventilation and room-conditioning systems in non-residential buildings:

• Use demand-controlled ventilation (DCV) systems to adjust the ventilation rate based on the occupancy and activity levels in a space.
• Use heat recovery systems to capture and reuse heat from exhaust air.
• Install energy-efficient fans and motors.
• Use natural ventilation when possible.
• Regularly maintain and test the ventilation and room-conditioning system.

By following these tips, you can help to ensure that the ventilation and room-conditioning system in your non-residential building meets the performance requirements and operates efficiently.
