EN 15316-4-4:2017

• Abstract:

  This European standard defines a method for the performance assessment of building-integrated cogeneration units by the calculation of the electricity production, useful heat output and recoverable losses. Such units are commonly known as micro or small scale cogeneration, or micro or small scale CHP.; A building-integrated cogeneration, is a cogeneration unit installed to supply space heating, domestic hot water and possibly cooling within a building. It could operate as the only heating/cooling appliance of the building or in combination with other heat generators, such as boilers or electrical chillers. Unlike district heating systems, where heat and electricity are generated at central plants and transmitted through networks to a number of remote buildings, a building-integrated cogeneration unit produces useful heat for uses within the building. The electricity produced by the integrated cogeneration unit may be used within the building or may be exported.; This standard deals with heat generators for heating or for combined domestic hot water and heating services.; The calculation is based on the performance characteristics of the units, defined in product standards, and on operation conditions such the needed heat output.; Table 1 shows the relative position of this standard within the set of EPB standards in the context of the modular structure as set out in prEN ISO 52000 1.; NOTE 1 In prCEN ISO/TR 52000 2 the same table can be found, with, for each module, the numbers of the relevant EPB standards and accompanying technical reports that are published or in preparation.; NOTE 2 The modules represent EPB standards, although one EPB standard may cover more than one module and one module may be covered by more than one EPB standard, for instance a simplified and a detailed method respectively. See also Clause 2 and Tables A.1 and B.1.

Overview

EN 15316-4-4:2017 is a CEN European standard for the energy performance of buildings focused on building‑integrated cogeneration systems (micro and small‑scale CHP / mCHP). It defines a method to calculate electricity production, useful heat output and recoverable losses for cogeneration units installed to supply space heating, domestic hot water (DHW) and potentially cooling within a single building. The standard is part of the modular EPB (Energy Performance of Buildings) set and covers Modules M8-3-4, M8-8-4, M8-11-4.

Key topics and requirements

• Performance assessment method: Calculation procedure to determine system energy requirements and system efficiencies for building‑integrated CHP based on product performance data and operating conditions.
• Outputs: Annual or time‑step based estimates of electricity produced, useful thermal output and recoverable thermal losses.
• Input data sources: Uses product standard characteristics (e.g., declared efficiencies) and building heat demand / load profiles to model operation.
• Calculation approach: Load‑profile based method with defined time steps and procedures to match CHP output to building heating and DHW needs.
• Scope of equipment: Applies to CHP appliances commonly called micro‑CHP, including fuel cell, internal combustion engine, Stirling, microturbine and ORC technologies (as described in the standard).
• Templates and defaults: Normative template in Annex A (mandatory choices) and informative default choices in Annex B facilitate consistent application and national adaptations.
• Quality assurance: Provisions for quality control and compliance checks to ensure reliable assessment and traceability.
• Regulatory use: Intended to support EPBD and EED implementation; regulators may set mandatory national choices or data sheets.

Applications and who uses it

• Energy assessors and consultants calculating building system energy performance.
• HVAC and CHP system designers performing sizing and integration studies.
• Manufacturers and product testers using declared product data for performance reporting.
• Building owners, facility managers and installers evaluating on‑site cogeneration feasibility and expected energy yields.
• Regulators and certification bodies adopting consistent methods for building energy codes and incentives.

— the individual user will apply the standard to assess the energy performance of a building, and thereby use the choices made by the regulators. Topics addressed in this standard can be subject to public regulation. Public regulation on the same topics can override the default values in Annex B of this standard. Public regulation on the same topics can even, for certain applications, override the use of this standard. Legal requirements and choices are in general not published in standards but in legal documents. In order to avoid double publications and difficult updating of double documents, a national annex may refer to the legal texts where national choices have been made by public authorities. Different national annexes or national data sheets are possible, for different applications.
