Thermal performance of buildings - In situ testing of completed buildings - Part 1: Data collection for aggregate heat loss test

This document specifies a test method for the in situ measurement of the thermal performance of buildings, both newly built and existing.
This document specifies the data to be collected during and after the test.
NOTE   The analysis of the data and the reporting format for the analysis are referred to in prEN 17887-2:2022 Thermal performance of buildings - In situ testing of completed buildings - Part 2: Steady-state data analysis for aggregate heat loss test.
This document is applicable to domestic scale detached buildings and attached domestic scale buildings, such as semi-detached houses, terraced houses and apartments.

Thermische Leistung von Gebäuden - In-situ-Tests von fertiggestellten Gebäuden - Teil 1: Datenerfassung für den Gesamtwärmeverlusttest

Dieses Dokument legt die stationären Datenanalyseverfahren fest, um damit die Daten aus der "Gesamtwärmeverlustprüfung" auszuwerten. Diese Analyseverfahren ermöglichen eine Abschätzung des tatsächlichen Gesamtwärmeverlustes vor Ort (Wärmetransferkoeffizient des Gebäudes).
ANMERKUNG   Das Verfahren zur Prüfung des Gesamtwärmeverlustes ist in prEN 17887-1:2022, Wärmetechnisches Verhalten von Gebäuden - In-situ-Prüfung an fertiggestellten Gebäuden - Teil 1: Datenerfassung für die Prüfung des Gesamtwärmeverlustes, festgelegt.

Performance thermique des bâtiments - Essais in situ des bâtiments achevés - Partie 1 : Collecte de données pour l’essai de déperdition thermique globale

Le présent document spécifie une méthode d’essai pour mesurer in situ la performance thermique des bâtiments récemment construits et des bâtiments existants.
Il spécifie les données à collecter pendant et après l’essai.
NOTE   L’analyse des données et le format de rapport pour l’analyse sont référencés dans le prEN 17887 2:2022 Performance thermique des bâtiments — Essais in situ des bâtiments achevés — Partie 2 : Analyse des données en régime stationnaire pour l’essai de déperdition thermique globale.
Le présent document s’applique aux bâtiments individuels et contigus destinés à une utilisation domestique, tels que les maisons jumelées, les maisons mitoyennes et les appartements.

Toplotne značilnosti stavb - Preskušanje dokončanih stavb na mestu vgradnje - 1. del: Zbiranje podatkov za preskus skupnih toplotnih izgub

Ta dokument določa preskusno metodo za merjenje toplotnih značilnosti na novo zgrajenih in obstoječih stavb na mestu vgradnje.
Določa podatke, ki jih je treba zbrati med preskusom in po njem.
OPOMBA:   Analiza podatkov in oblika poročanja za analizo sta navedeni v standardu prEN 17887-2:2022 Toplotne značilnosti stavb – Preskušanje dokončanih stavb na mestu vgradnje – 2. del: Analiza podatkov v stanju dinamičnega ravnovesja za preskus skupnih toplotnih izgub.
Ta dokument se uporablja za samostojne in povezane stanovanjske stavbe, kot so dvojčki, vrstne hiše ali stanovanja.
