19. Cost-efficient Nearly Zero-Energy Buildings

Author

Environmental sciences, GE1-350
Abstract

The next level of energy performance of new buildings within the European Union will be the Nearly Zero-Energy Building (NZEB). A lot of work has been spent on pilot and demonstration buildings on this and also even higher energy performance levels throughout all EU countries. However, most of the high performance buildings realised so far result in higher investment costs when compared to the current national minimum energy performance requirements. The considerably higher investment costs are one of the main barriers to the early application of the NZEB-level in Europe. The EU H2020 project CoNZEBs works on technical solution sets that result in lower investment costs for NZEBs, bringing the costs close to those of conventional new buildings. The focus is on multi-family houses. In each of the four participating countries Germany, Denmark, Italy and Slovenia a team of researchers is analysing which sets of marketready technologies at the building envelope, the services systems for heating, domestic hot water, ventilation and cooling (where required) in combination with renewable energy systems can fulfil the NZEB requirements at lower costs than those incurred by the national mainstream NZEB application. Additional efforts are being spent on the life-cycle costs and the life-cycle analysis of the solution sets, as well as on the impact of future developments of primary energy factors, energy costs and technology efficiencies.

39. Kostengünstig und energieeffizient

Author

Erhorn-Kluttig, Heike, Erhorn, Hans, Illner, Micha, and Publica

Abstract

Wie können kostengünstig energetisch hocheffiziente Wohngebäude konzipiert und gebaut werden, die nur minimale Mehrinvestitionen gegenüber einer Standardausführung bedingen? Wie wirkt sich das auf die Lebenszykluskosten und die Ökobilanz aus, d. h. die Primärenergie und die Treibhausgasemissionen inklusive der Herstellungsphase? Welche kostensparenden Energiekonzepte sind auch in zehn Jahren noch vorteilhaft? Diese Fragestellungen hat das EU-Projekt CoNZEBs untersucht. Die wichtigsten Erkenntnisse aus dieser Studie fasst der zweiteilige Artikel zusammen.

40. Software für Quartiersenergiekonzepte

Author

Erhorn-Kluttig, Heike, Wössner, Simon, Budde, Eike, Erhorn, Hans, and Publica

Abstract

Die Bundesregierung hat für Deutschland hohe Klimaschutzziele gesetzt. Bis zum Jahr 2050 soll u.a. der deutsche Gebäudebestand nahezu klimaneutral werden. Um dies zu erreichen muss der Energiebedarf der Gebäude im Neubau und Bestand reduziert und die Energieversorgung umfassen auf erneuerbare Energieträger umgestellt werden. Dabei sind neben Energiekonzepten für Einzelgebäude auch Quartiersenergiekonzepte interessant. Das Fraunhofer-Institut für Bauphysik hat mit dem District Energy Concept Adviser ein Tool für die frühe Planungsphase von Quartieren entwickelt.

41. Solution sets for NZEB multi‐family houses and beyond assessed for 2030 ; Deliverable D6.1:Solution sets for the Cost reduction of new Nearly Zero‐Energy Buildings – CoNZEBs

Abstract

The main goal of the EU Horizon 2020 project CoNZEBs was to identify technology combinations for multi‐family houses that fulfil the Nearly Zero‐Energy Building (NZEB) requirements but result in lower investment costs if compared to the typical (mainstream) NZEB technology combinations. The national CoNZEBs teams from Germany, Denmark, Italy and Slovenia were successful in finding at least four alternative technology combinations(aka alternative NZEB solution sets) per country. These solution sets and many of the contained innovative technologies are described in detail in a report [1] available on the project website. In a second step the NZEB solution sets and a technology combination achieving a building energy level beyond NZEB (zero energy building or plus energy building) have been assessed in comparison to the typical NZEB and a building fulfilling the national minimum energy performance requirements regarding life‐cycle costs and life‐cycle impact[28].This report now seeks to look ahead into future developments of certain factors that have an impact on the energy performance, investment costs or energy costs of the determined solution sets. The relevant impact factors are primary energy factors, energy prices, technology costs and technology efficiencies. For each of these impact factors the developments by the year 2030 were predicted, based on available national studies or where not available based on the personal evaluation of the project partners.

42. Solutions sets for cost optimisation of nearly zero energy buildings (NZEBs) in four European countries

Abstract

Nearly zero energy buildings (NZEBs) are required as the minimum standard for all new buildings in Europe by January 2021. NZEBS should, according to the Energy Performance of Buildings Directive (EPBD) [1], be cost optimal, i.e. the cost of constructing and operating the building over its lifetime should be at its minimum. The EU Horizon2020 research project CoNZEBs, identify and assess technology solution sets that lead to cost reductions of new NZEBs in four EU member states. Focussing on buildings that comply with national NZEB requirements, designers can easily ignore alternative solutions that make the building cheaper while remaining within national requirements. This is not done intentionally, but primarily due to use of a traditional design thinking where optimisation is done on component level instead of a more holistic approach. Changing one building component may influence the cost and performance of other components. These alternative solutions take offset in a typical national multi-family building design and analyses the different lifetime costs in terms of costs for construction, and energy. Analyses of costs in different countries reveals different solutions sets being optimal. In CoNZEBs we compare different solution sets and investigate the possibility for “exporting” solution sets from one country to another.
