Abstract: Since 2012, Life Cycle Engineering Experts (LCEE) have carried out a series of comprehensive studies into the sustainability of market‐relevant (also potentially) construction methods in German housing ([1] to [4]). The methodical basis was a systematic application of the sustainability assessment approach of the Deutsches Gütesiegel Nachhaltiges Bauen (DGNB) applied to representative model buildings from the detached house and apartment building sectors (see Figs. 1 and 2). The key findings have been compressed into themed fact sheets intended to ensure appropriate knowledge and information transfer to various recipients. As a contribution to less marketing and more reality, the following paper outlines the lessons learnt from selected example fact sheets concerning sustainable housing. [ABSTRACT FROM AUTHOR]

The construction and real estate industry in general and residential buildings in particular are essential pillars of the national sustainability strategy in Germany and extremely important for resilient socio-economic development. By performing life-cycle examinations of different building types, the Institute for Concrete and Masonry Structures at Darmstadt University of Technology has analysed the sustainability characteristics of residential masonry buildings with regard to common German sustainability certification systems. This paper gives an overview of the key findings of the examinations. It is a condensed version of the authors' article for the 9th International Masonry Conference 2014 in Portugal [1] and at the same time a preview of a forthcoming paper in this journal (Vol. 18, No. 5).

Over recent years, the authors have released various research findings concerning the sustainability of masonry construction for detached houses [1] and apartment buildings [2] in comparison with alternative construction methods (timber, reinforced concrete). Meanwhile, in cooperation between the Institute for Concrete and Masonry Structures, TU Darmstadt, and its spinoff LCEE Life Cycle Engineering Experts, these analyses have been merged to a further study with increased consideration of all relevant construction methods for multi-floor residential buildings; preliminary results have already been presented in this journal [3]. The following paper now shows the final findings including data updates, added construction variants (imported timber scenario) and extended life cycles (50 and 80 years). [ABSTRACT FROM AUTHOR]

Ecology, energy and sustainability are crucial socio-economic keywords, especially for the construction and real estate industry. In recent years, the masonry industry faced related sustainability issues intensively in order to keep its ability of operating in a market setting which is increasingly characterized by sustainability dogmata. Scientific analyses and studies on an objectified sustainability basis - such as established certification systems - show that masonry is absolutely competitive with all other market-relevant construction methods. Therefore, the first part of this paper deals with a sustainability assessment of buildings made of masonry as well as of other construction materials. Concerning the design and construction of masonry, further selected aspects are discussed which are important for the competitiveness of this building technique. Outlining the simple yet economic pre-dimensioning with the help of load capacity tables is one topic which is of utmost importance for an efficient structural design. Additional aspects are the design of laterally loaded exterior walls with low vertical forces and the verification of basement walls under high earth pressure load. New and easy to use design proposals are open for discussion. Finally, the educational portal 'masonry structures' of the Deutsche Gesellschaft für Mauerwerks- und Wohnungsbau (DGfM) (German society for masonry and residential construction), which supports the training of young engineers, is presented.

Innerhalb der deutschen Nachhaltigkeitsstrategie spielen die Bau- und Immobilienwirtschaft im Allgemeinen und Wohngebäude als wichtige Gebäudetypologie im Speziellen eine zentrale Rolle. Auf Basis einer ganzheitlichen lebenszyklusorientierten Analyse konnte die hohe Nachhaltigkeitsqualität kleiner Wohngebäude (EFH/ZFH) aus Mauerwerk bereits nachgewiesen werden [1]. Die Untersuchungen dieses Beitrags weiten diese Betrachtungsweise aus und sollen zeigen, ob auch größeren Mauerwerkswohngebäuden (MFH) eine vergleichbare Nachhaltigkeitsqualität attestiert werden kann. Masonry and sustainability in apartment buildings. The construction and real estate industry in general and especially residential buildings as a crucial typology are key elements of the national sustainability strategy in Germany. Based upon a holistic life-cycle orientated analysis the high sustainability quality of small residential buildings made of masonry has already been verified [1]. The examination of the following paper extends the perspective and should prove if masonry apartment buildings can be characterised by a comparably high sustainability quality.

Einfamilienhäuser gehören zu der beliebtesten Wohnform in Deutschland. Große Teile der Bevölkerung streben den Besitz eines Einfamilienhauses an. Gleichzeitig stehen Einfamilienhäuser in der Kritik nicht nachhaltig zu sein, weil sie zu einem erhöhten Flächen- sowie Ressourcenverbrauch beitragen und häufig nicht an die sich wandelnden Lebensumstände der Eigentümer angepasst werden können. Um dieser Kritik entgegenzuwirken, bedarf es eines einfachen, transparenten Instrumentes zur Darstellung der Nachhaltigkeitsqualität von Einfamilienhäusern. Mit dem in diesem Beitrag vorgestellten Bewertungssystem kann die Qualität eines Einfamilienhauses in ökologischer, ökonomischer und sozial-funktionaler Sicht mit geringem Aufwand beurteilt werden. Aufbauend darauf ist eine gezielte Optimierung des Gebäudes und damit verbunden der Nachhaltigkeit möglich. Sustainable Living - Assessing the quality of sustainability single-family homes. Single-family homes are the most popular forms of living. Large parts of the population aspire to the possession of a family home. At the same time houses are in critique to not to be sustainable because they contribute to increased land-and resource requirements, and often cannot be adapted to the changing circumstances of the owner. To counter this criticism, we need a simple transparent instrument to represent the quality of sustainable family homes. As presented in this paper, the quality evaluation system of a single-family home may be assessed in an ecological, economic and social-functional perspective with little effort. Based on this, a targeted optimization of the building and thereby of sustainability is possible. [ABSTRACT FROM AUTHOR]

Der Bau- und Immobilienwirtschaft kommt für eine nachhaltige gesellschaftliche und wirtschaftliche Entwicklung eine Schlüsselrolle zu. In diesem Kontext haben Wohngebäude aufgrund ihres großen Anteils am Gebäudebestand eine besondere Bedeutung. Im Rahmen einer ganzheitlichen lebenszyklusorientierten Untersuchung wurde am Institut für Massivbau der TU Darmstadt analysiert, welche Nachhaltigkeitsqualität kleinen Wohngebäuden aus Mauerwerk - als der marktbestimmenden Bauweise - attestiert werden kann. Der Beitrag stellt wichtige Ergebnisse bezüglich der Nachhaltigkeit von Ein-und Zweifamilienhäusern vor und ist die verkürzte Fassung eines Beitrags der Autoren im Praxishandbuch Mauerwerksbau aktuell 2014 [1]. Germany relies on - sustainability of masonry residential buildings. The construction and real estate industry plays a key role for a sustainable social and economic development. Due to their large share in the building stock, residential buildings have an extraordinary importance. Thus, the Institut für Massivbau at Technische Universität Darmstadt analysed by doing a holistic, life-cycle orientated examination, what Ievel of sustainability quality small residential buildings made of masonry have. This paper presents key findings concerning the sustainability of single and two-family houses of masonry and is an abbreviated version of the authors' article in 'Mauerwerksbau aktuell 2014'.
