What is BS EN 15316-4-3-Energy performance of buildings about?
BS EN 15316 discusses the energy performance of buildings. BS EN 15316-4 belongs to BS EN 15316 multi-series and discusses heat generation systems, thermal solar and photovoltaic systems, Module M3-8-3, M8-8-3, M11-8-3.
BS EN 15316-4-3 specifies the required inputs, calculation method, required and resulting outputs for heat generation systems, thermal solar systems (for space heating, domestic hot water production, and the combination of both), and for photovoltaic systems applied in buildings.
Who is BS EN 15316-4-3-Energy performance of buildings for?
BS EN 15316-4-3 on the energy performance of buildings (Heat generation systems, thermal solar, and photovoltaic systems) is useful for:
- Solar heater manufacturers
- Architects
- Heater manufacturers
- Civil engineers
- Design engineers
- HVAC (Heating, ventilation, and air conditioning) engineers
- Builders
Why should you use BS EN 15316-4-3-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 15316-4-3 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 15316-4-3 provides you with six methods each method has its own range of applicability:
Method 1 is applicable for solar domestic hot water systems characterized by the EN 12976 series (factory-made) or EN 12977-2 (custom built). The main output of the method is the solar heat and backup heat contribution to the requested heat use.
Method 2 is applicable for systems for domestic hot water and/or space heating with components characterized by EN ISO 9806 and EN 12977-3 or EN 12977-4 with a monthly calculation time step. The main output of the method is the solar heat and backup heat contribution to the requested heat use.
Method 3 is applicable for systems for domestic hot water and/or space heating with components characterized by EN ISO 9806 with an hourly calculation time step. The main output of the method is collector loop heat supplied to the heat storage.
Method 4 is applicable for photovoltaic systems with components characterized by standards and with an annual calculation time step. The output of the method is the produced electricity.
Method 5 is applicable for photovoltaic systems with components characterized by standards and with a monthly calculation time step. The output of the method is the produced electricity.
Method 6 is applicable for photovoltaic systems with components characterized by standards and with a calculation time step. The output of the method is the produced electricity.
What’s changed since the last update?
BS EN 15316-4-3:2017 supersedes BS EN 15316-4-3:2007 and BS EN 15316-4-6:2007, which are withdrawn. It includes some technical changes. These include:
- Extensions to the former Method B, e.g. full support of solar systems with integrated backup heating and extension with the effect of the heat storage heat losses
- Method 3 is added to broaden the applicability of the solar thermal methods to calculations with an hourly time step
- The revision brings the method in conformity with the methods used in Ecodesign and the energy labelling (CEN mandate 495)
- Addition of a new method to support input with an hourly time step
- Editorial changes
