Energy performance of buildings - Economic evaluation procedure for energy systems in buildings

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.

Energieeffizienz von Gebäuden - Wirtschaftlichkeitsberechnungen für Energieanlagen in Gebäuden

Diese Norm beschreibt ein Berechnungsverfahren für die wirtschaftlichen Aspekte von Heizungsanlagen und anderen Systemen, die in den Energiebedarf und den Energieverbrauch eines Gebäudes einbezogen sind. Diese Norm gilt für alle Gebäudearten.
Die grundsätzlichen Prinzipien und Fachausdrücke sind in dieser Norm erläutert.
Die hauptsächlichen Bestandteile der Norm sind:
   Definitionen und Strukturen jener Kostenarten, die für die Berechung der Wirtschaftlichkeit der Einspar¬möglichkeiten in Gebäuden in Betracht gezogen werden müssen;
   Daten, die zur Definition jener Kosten nötig sind, die mit den betrachteten Anlagen in Verbindung stehen;
   Berechnungsverfahren;
   Darstellung der Ergebnisse der wirtschaftlichen Berechnung;
   informative Anhänge mit Anhaltswerten für z. B. Lebensdauer, Reparaturkosten, Instandhaltungskosten, um damit Anhaltswerte für Berechnungen zu erhalten.
Diese Norm ist Teil des Berechnungsverfahrens für die Wirtschaftlichkeit von Energieeinsparungsmöglich¬keiten in Gebäuden (z. B. Wärmedämmung, effizientere Erzeugungs  und Verteilungssysteme, effiziente Beleuchtung, erneuerbare Quellen, Kraft Wärme Kopplung).
Der Anwendungsbereich dieses speziellen Teils ist zur Vereinheitlichung von:
   benötigten Eingangswerten;
   Berechnungsverfahren;
   benötigten Ausgangswerten
zur wirtschaftlichen Berechnung von Energiesystemen in Bezug auf die Energieeffizienz von Gebäuden.
ANMERKUNG   Die Aussagekraft der Ergebnisse steigt mit der Anzahl der betrachteten Parameter (z. B. Lebensdauer, Zinssätze, Entwicklung von verschiedenen Kostenarten). Je mehr Parameter beim Vergleich verschiedener Möglichkeiten geändert werden, desto schwieriger ist es, Schlüsse aus den wirtschaftlichen Ergebnissen der Berechnungen zu ziehen.
Die Wirtschaftlichkeitsergebnisse stehen in enger Verbindung mit dem jeweils betrachteten Projekt, sodass daraus keine allgemein gültigen Schlüsse gezogen werden sollten.

Where possible, reference is made to other European or International Standards, a.o. product standards. However, use of products complying with relevant product standards is no guarantee of compliance with the system requirements. The requirements are mainly expressed as functional requirements, i.e. requirements dealing with the function of the system and not specifying shape, material, dimensions or the like.
The guidelines describe ways to meet the requirements, but other ways to fulfil the functional requirements might be used if fulfilment can be proved. Heating systems differ among the member countries due to climate, traditio
