CEN/TC 228/WG 4 - Calculation methods and system performance and evaluation

This European Standard describes 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 a comparatively small heating power and large storage volumes.
This European Standard 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), nominated in this standard as "mixed storage systems";
and for different uses.
The Scope also includes standardization methods for determining the energy need for domestic hot water. This European Standard covers the domestic hot water needs in buildings.
The calculation of the energy needs for DHW-Systems applies to residential and non-residential buildings, a building or a zone of a building.

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.

general definition of the overall energy use (i.e. determine which services are taken into account within the system boundaries);
definition of energy terms (energy use, primary energy, etc.);
definition of the data interfaces with other standards in order to report the overall energy use of buildings;

- distinguish between thermal uses and specific electrical uses;
- indicate the outputs required f

This European Standard is part of a set of standards covering methods for calculation of system energy requirements and system efficiencies of heating systems in buildings. In particular this European Standard is one of a number of standards dealing with domestic hot water systems.
The scope of this specific part is to standardise the methods for determining the energy needs for domestic hot water. This European Standard covers the domestic hot water needs in buildings.
The calculation of the energy needs for domestic hot water applies to a dwelling, a building or a zone of a building.
In order to be coherent with calculation methods for space heating systems, emission losses representing taps and control should be taken into account.

This standard gives methods for calculating heat losses for basic cases at thed design conditions. This standard gives a method for calculating the design heat load for basic cases under the design conditions. Basic cases are the majority of all buildings to be found in practise with a limited room height (not exceeding 5 meters) and assumed to be heated to steady state conditions under the design conditions.

This standard provides a calculation method for the economical issues of heating systems and other systems that are involved in the energy demand and energy consumption of the building. This standard applies to all types of buildings.
The fundamental principles and terminology are explained in this standard.
The main items of the standard are:
-   definitions and structure of the types of costs, which shall be taken into account for calculation of the economical efficiency of saving options in buildings;
-   data needed for definition of costs related to systems under consideration;
-   calculation method(s);
-   expression of the result of the economic calculation;
-   informative annexes indicating default values of e.g. lifetime, costs for repair, costs for maintenance, in order to introduce default values for calculations.
This standard is applicable to calculation of economic performance of energy saving options in buildings (e.g. insulation, better performing generators and distribution systems, efficient lighting, renewable sources, combined heat and power).
The scope of this standard is to standardise:
-   required inputs;
-   calculation methods;
-   required outputs
for economic calculations of energy systems related to the energy performance of buildings.
NOTE   Sensitivity of results increases with the number of parameters under consideration (e.g. lifetime, interest rates, development of different types of costs). The more parameters one changes when comparing different solutions, the more difficult it is to draw conclusions from the economic results of the calculations.
Economical results are closely related to the specific project under consideration, and no general conclusions should be drawn from any such results.

The scope of this European Standard is to standardise the required inputs, the outputs and the links (structure) of the calculation method in order to achieve a common European calculation method.
The energy performance may be assessed either by values of the heat emission system efficiency or by values of the increased space temperatures due to heat emission system inefficiencies.
The method is based on an analysis of the following characteristics of a space heating emission system, including control:

-   heat emitters embedded in the building structure;
-   control accuracy of the indoor temperature.
The energy required by the emission system is calculated separately for thermal energy and electrical energy, in order to facilitate determination of the final energy and subsequently the corresponding primary energy according to other standards.
