Energy conservation potential in existing buildings; Energiesparpotentiale im Gebaeudebestand

Abstract

In 1987 the final energy consumption in the FRG amounted to 2090 TWh. 730 TWh or 35% of the energy has been used for space heating. Space heating therefore has the highest share in the final energy consumption. At the same time it is the form of energy with the lowest exergy share and it is obvious that especially in this area minimum use of high-quality fuels has to suffice to ensure the desired energy service, e.g. a room temperature of 18-20deg C. The technical possibilities for the reduction of the heating energy demand are presented and discussed in chapter 2. This study is restricted to heating energy consumption in the housing sector. In this field better statistical material is available than for other sectors. Moreover for space heating of private households with 470 TWh/a about two third of the final energy is consumed. For households space heating plays the most important role: its share of final energy consumption amounts to nearly 80%. Possible savings by doing without a part of the energy services by reducing the average air temperature is also quantified in this work. It lies with 9% per kelvin for existing buildings considerably below the technical potentials.  More>>

It lies with 9% per kelvin for existing buildings considerably below the technical potentials. Above all even if the motivation is high in the beginning no long term saving effect can be expected as the development after the oil price shock has shown. Permanent energy savings can only be guaranteed by technical measures. The measures presented in detail in this study (chapter 4) are technically proven and economically justifiable. The technical possibilities for heating energy savings are thus not by any means exhausted. With increased acceptance of thermal insulation measures it is most probable that in the medium and long term further and better techniques will be developed and introduced to the market. (orig./UA). [Deutsch] Im Jahre 1987 betrug der Endenergieverbrauch in der Bundesrepublik Deutschland 2090 TWh. Der Energieeinsatz fuer die Raumwaerme betrug dabei 730 TWh oder 35%. Die Raumwaerme ist damit die Einzelanwendung mit dem hoechsten Anteil am Endenergieverbrauch. Gleichzeitig ist sie die Energieform mit dem geringsten Exergieanteil, und es liegt auf der Hand, dass daher gerade in diesem Bereich ein minimaler Einsatz hochwertiger Energierohstoffe ausreichen muss zur Erbringung der gewuenschten Energiedienstleistung, einer Raumtemperatur von ca. 18-20deg C. Die technischen Moeglichkeiten zur Verminderung des Heizenergiebedarfs werden in Kapitel 2 vorgestellt und diskutiert. Die vorliegende Studie beschraenkt sich auf den Heizenergieverbrauch im Bereich der Wohngebaeude. Fuer diesen Bereich steht besseres statistisches Datenmaterial zur Verfuegung als fuer die anderen Sektoren. Darueberhinaus wird mit 470 TWh/a ca. zwei Drittel der Endenergie fuer die Raumwaerme von den privaten Haushalten verbraucht. Fuer die Haushalte selbst spielt die Raumwaerme die groesste Rolle: Ihr Anteil am Endenergieverbrauch betraegt fast 80%. Die moegliche Einsparung durch den Verzicht auf einen Teil der Energiedienstleistung durch Absenkung der durchschnittlichen Raumlufttemperatur wird in dieser Arbeit ebenfalls quantifiziert. Sie liegt mit ca. 9% pro Kelvin bei Gebaeuden im Bestand erheblich unter den technischen Potentialen. Vor allem ist selbst bei anfaenglich hoher Motivation kein langfristiger Einspareffekt zu erwarten, wie auch die Entwicklung nach den Oelpreisschocks gezeigt hat. Bleibende Energieeinsparungen koennen nur durch technische Massnahmen garantiert werden. Die in dieser Studie im Detail vorgestellten Massnahmen sind technisch erprobt und wirtschaftlich vertretbar. Die technischen Moeglichkeiten zur Heizenergieeinsparung sind damit bei weitem nicht ausgeschoepft. (orig./UA).}
