What is BS EN 12831-3-Energy performance of buildings about?
BS EN 12831 discusses the energy performance of buildings and the method for calculation of the design heat load. BS EN 12831-3 is the third part of BS EN 12831 multi-series and discusses domestic hot water systems heat load and characterisation of needs, Module M8-2, M8-3.
BS EN 12831-3 is applicable to the following water storage systems
Storage systems characterized by a minimal mixing zone, (such as stratified charging storage tanks or storage tanks with external heat exchangers): these systems are nominated in this standard as “charging storage systems.
Storage tank water heaters and warm water storage tanks with a pronounced mixing zone (such as DHW storage tanks with internal heat exchangers), are nominated in this standard as “mixed storage systems”.
BS EN 12831-2 provides methods for determining the energy need for domestic hot water. BS EN 12831-2 covers the domestic hot water needs in buildings. The calculation of the energy needs for DHW (domestic hot water systems)-Systems applies to residential and non-residential buildings, a building, or a zone of a building.
Who is BS EN 12831-3-Energy performance of buildings for?
BS EN 12831-3 on the energy performance of buildings and method for calculation of the design heat load (domestic hot water systems) is useful for:
- Architects
- Civil engineers
- Design engineers
- HVAC (Heating, ventilation, and air conditioning) engineers
- Builders
- Plumbers
- Constructors/contractors who install plumbing systems
Why should you use BS EN 12831-3-Energy performance of buildings?
The energy efficiency of a building is the extent to which the energy consumption per square meter of the floor area of the building measures up to established energy consumption benchmarks for that particular type of building under defined climatic conditions.
BS EN 12831-3 is part of a series of standards aiming at international harmonization of the methodology for the assessment of the energy performance of buildings, called the “set of EPB standards.
BS EN 12831-3 provides you with a method to calculate the power and the storage volume required for the dimensioning of domestic hot water systems (DHW). The applicability ranges from direct water heaters (no storage volume and a comparatively large effective heating power) to larger storage systems with comparatively small heating power and large storage volumes.
