Heating systems in buildings - Design of embedded water based surface heating and cooling systems - Part 3: Optimizing for use of renewable energy sources
This document is applicable to water based surface heating and cooling systems in residential, commercial and industrial buildings.
The methods apply to systems integrated into the wall, floor or ceiling construction without any open air gaps.
The methods do not apply to heated or chilled ceiling panels or beams.
This standard is part 3 of a series of standards:
- Part 1: Determination of the design heating and cooling capacity;
- Part 2: Design, dimensioning and installation;
- Part 3:Optimizing for use of renewable energy sources.
The aim of the present standard is to give a guide for the design to promote the use of renewable energy sources and to provide a method for the use of Thermo-Active-Building-Systems (TABS).
The method allows calculation of peak cooling capacity of a thermo-active system, based on heat gains (solar, internal loads, ventilation).
This method also allows calculation of the energy demand on the water side (system) to be used for sizing of the cooling system, e.g. chiller, fluid flow rate.
Steady state heating capacity is calculated according to method B or E of prEN 15377-1 (part 1 of this series of standards).
Heizungsanlagen in Gebäuden - Planung von eingebetteten Flächenheiz- und -kühlsystemen mit Wasser als Arbeitsmedium - Teil 3: Optimierung für die Nutzung erneuerbarer Energiequellen
Dieses Dokument gilt für Flächenheiz und kühlsysteme mit Wasser als Arbeitsmedium in Wohnhäusern, Geschäfts und Industriebauten.
Die Verfahren gelten für in Wand , Decken oder Fußbodenkonstruktionen eingebaute Systeme ohne offene Luftspalte.
Die Verfahren gelten nicht für beheizte oder gekühlte Deckenplatten oder strahler.
Diese Norm ist Teil 3 einer Reihe von Normen, die folgende Teile umfasst:
Teil 1: Berechnungsverfahren zur Bestimmung der Auslegungs -Heiz- und -Kühlleistung unter stationären Bedingunen;
Teil 2: Verfahren für die Auslegung, Dimensionierung und Installation;

Das Ziel der vorliegenden Norm besteht darin, einen Leitfaden für die Planung bereitzustellen, um die Nutzung erneuerbarer Energiequellen zu fördern sowie ein Verfahren für den Einsatz von thermoaktiven Bauteilsystemen (TABS) zur Verfügung zu stellen.
Dieses Verfahren ermöglicht die Berechnung der Spitzenkühlleistung eines thermoaktiven Systems auf der Basis der (solaren und durch interne Lasten oder die Lüftung verursachten) Wärmegewinne.
Dieses Verfahren ermöglicht auch die Berechnung des Energiebedarfs auf der Wasserseite (System), der für die Dimensionierung des Kühlsystems, z. B. des Wasserkühlers und des Flüssigkeitsstroms, verwendet wird.
Die Heizleistung unter den Bedingungen des Beharrungszustandes wird nach Verfahren B oder E von prEN 15377 1 (Teil 1 dieser Normenreihe) berechnet.
Systèmes de chauffage dans les bâtiments - Conception des systèmes de chauffage et de refroidissement de surfaces à eau intégrés - Partie 3 : Optimisation de l'utilisation des énergies renouvelables
Ce document s’applique aux systèmes de chauffage et de refroidissement de surfaces à eau dans les bâtiments résidentiels, commerciaux et industriels.
Les méthodes s’appliquent aux systèmes intégrés dans la construction des murs, du plancher ou du plafond sans aucune poche d’air ouverte.
Elles ne s’appliquent pas, en revanche, aux panneaux ou poutres de plafond chauffés ou réfrigérés.
La présente norme est la troisième partie d’une série de normes :
Partie 1 : Détermination de la puissance calorifique et frigorifique de conception ;
Partie 2 : Conception, dimensionnement et installation ;
Partie 3 : Optimisation de l’utilisation des énergies renouvelables.
La présente norme vise à fournir un guide pour une conception promouvant le recours à des sources d’énergie renouvelables et à proposer une méthode pour l’utilisation de systèmes d’éléments de construction thermoactifs (TABS).
La méthode permet de calculer la puissance frigorifique de pointe d’un système thermoactif sur la base des apports de chaleur (solaire, charges internes, ventilation).
Elle permet également de calculer la demande d’énergie côté eau (système) à utiliser pour le dimensionnement du système de refroidissement (par exemple, refroidisseur, débit du fluide, etc.).
La puissance calorifique en régime permanent est calculée selon la méthode B ou E du prEN 15377-1 (Partie 1 de cette série de normes).

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, traditions and national regulations. In some cases requirements are given as classes so national or individual needs may be accommodated. In cases where the standards contradict with national regulations, the latter should be followed. prEN 15377 Heating systems in buildings – Design of embedded water based surface heating and cooling systems consists of the following parts: Part 1: Determination of the design heating and cooling capacity Part 2: Design, dimensioning and installation Part 3: Optimizing for use of renewable energy sources
A section in the present standard describes how the design and dimensioning can be improved to facilitate renewable energy sources. Peak loads can be reduced by activating the building mass using pipes embedded in the main concrete structure of the building (Thermo-Active-Building-Systems, TABS). For this type of systems, the steady state calculation of heating and cooling capacity (part 1 of this standard) is not sufficient. Thus, several sections of this standard describe methods for taken into account the dynamic behavior. The proposed methods are used to calculate and verify that the cooling capacity of the system is sufficient and to calculate the cooling requirements on the water side for sizing the cooling system. The energetic assessment of surface heating and cooling systems may also be carried out according to national guidelines accomplishing the goal of this standard.
The method allows calculation of peak cooling capacity of a thermo-active system, based on heat gains (solar, internal loads, ventilation). This method also allows calculation of the energy demand on the water side (system) to be used for sizing of the cooling system, e.g. chiller, fluid flow rate. Steady state heating capacity is calculated according to method B or E of prEN 15377-1 (part 1 of this series of standards). 2 Normative references The following referenced documents are indispensable for the application of this standard.
