“…The difference in CO2 emission between two cases originates from the use of larger mass intensities of steel, concrete, precast concrete, wooden parquet, and wooden windows in Case A as opposed to Case B, which uses less concrete and more bricks and other insulation materials. The total embodied carbon emission of Case B is closer to the one of modern residential buildings built in the Czech Republic, which totals in average 230 kg CO 2 /m 2 (Lupíšek et al , 2015). In relation to this, the study in South Korea found that various construction materials of an apartment unit produced around 569.5 kg CO 2 /m 2 on average (Jeong et al , 2012).…”

Purpose The purpose of this paper is to quantify the carbon emissions emitted by two different typical apartment units representative of two different construction periods in Kosovo due to main construction materials as a consequence of embodied energy. Design/methodology/approach The present study uses a three-step (bottom-up) process-based life cycle analysis of the construction material set for two different apartment units. The current study uses material analysis. Embodied CO2 is estimated by multiplying material masses with the corresponding ECO2 coefficients (kg CO2/kg). Due to the lack of a comprehensive Kosovo database, data from an international database are utilized. The results provide practical baseline indicators for the contribution of each material in terms of mass and embodied CO2. Findings Results of quantitative research find that apartment unit representative of the old communist-era construction produces 50 percent more embodied CO2 emissions than an apartment unit that is representative of modern construction in Kosovo. The study finds that this difference comes mainly because of the utilization of larger quantities of steel, concrete, and precast fabricated concrete in the apartment unit that is representative of the old communist era. Research limitations/implications The calculation of embodied CO2 emissions for major construction materials in typical apartments in Kosovo can help in the development of national databases in the future. The availability of such databases could help the construction industry in Kosovo to open up to new sustainable design approaches since such databases and evaluations performed in the national context in Kosovo could help the builders in selecting, assessing and using environmentally friendly materials during the design or refurbishment stage of a building. Originality/value This paper is the first investigation of the embodied carbon emission in two different typical apartment building structures in Kosovo.

“…Some researchers have reviewed the environmental impacts of wood products and alternative materials in buildings and found that wood outperforms alternative materials in terms of greenhouse gas emissions. Compared to other materials, wood has been found to produce less waste, and has performed better across different impact categories, except preservative-treated wood [39]. At present, different engineering timber (GLT, CLT) is used in the building industry that need preservatives.…”

Life Cycle Environmental Sustainability and Energy Assessment of Timber Wall Construction: A Comprehensive Overview

et al. 2022

View full text Add to dashboard Cite

This article presents a comprehensive overview of the life cycle environmental and energy assessment for all residential and commercial constructions made of timber walls, globally. The study was carried out based on a systematic literature analysis conducted on the Scopus database. A total of 66 research articles were relevant to timber wall design. Among these, the residential construction sector received more attention than the commercial sector, while the low-rise construction (1–2 stories) gained more attention than high-rise construction (>5 stories). Most of these studies were conducted in Canada, Europe, Malaysia, and the USA. In addition, the end-of-life phase received limited attention compared to upstream phases in most of the studies. We compared all environmental and energy-based life cycle impacts that used “m2” as the functional unit; this group represented 21 research articles. Global warming potential was understandably the most studied life cycle environmental impact category followed by acidification, eutrophication, embodied energy, photochemical oxidation, and abiotic depletion. In terms of global warming impact, the external walls of low-rise buildings emit 18 to 702 kg CO2 kg eq./m2, while the internal walls of the same emit 11 kg CO2 kg eq./m2. In turn, the walls of high-rise buildings carry 114.3 to 227.3 kg CO2 kg eq./m2 in terms of global warming impact. The review highlights variations in timber wall designs and the environmental impact of these variations, together with different system boundaries and varying building lifetimes, as covered in various articles. Finally, a few recommendations have been offered at the end of the article for future researchers of this domain.

tionen ersetzt (Bild 2), die natürlich aktuellen Energieanforderungen entsprechen. Die Hauptidee eines Forschungsvorhabens [2] war es, eine Alternative zu entwickeln, die eine ähnliche Systemlösung mit minimiertem Einsatz von Metallen und Erdölprodukten, mit hoher Energieeinsparung und mit garantiert hohem Komfort im Inneren bietet. Es war von Anfang an klar, dass es sich neben konstruktiven Fragen um eine sehr komplexe bauphysikalische Aufgabe handelt. Solche neuartige Fassade wurde zusammen mit ihren Schlüsselcharakteristika bereits vorgestellt [3], [4]. Es handelt sich um eine völlig vorgehängte Fassade mit geschosshohen Elementen (Bild 3). Jedes Element ist mit Hilfe von Stahlankern in der Decke oder im parallel laufenden Deckenbalken befestigt. Im oberen Teil jedes Elementes befindet sich die zukünftige Fensterbrüstung; die Fenster sind im unteren Teil angeordnet. Solche von [5] übernommene Anordnung ist für die Arbeit auf der Baustelle vorteilhaft: Sie ermöglicht einen guten Zugang zur horizontalen Fuge zwischen den Elementen. Der Beitrag befasst sich mit der Entwicklung einer Systemlösung für den Ersatz alter nichttragender Außenwände bei Nichtwohngebäuden aus den 1960er und 1970er Jahren. Die Hauptidee war, ein vorgefertigtes Produkt in moderner Holzbauweise zu entwickeln, um eine Alternative zu üblichen Metallbausystemen anzubieten. Es wurde bestätigt, dass ohne detaillierte bauphysikalische Analysen und Messungen eine erfolgreiche Entwicklung kaum möglich ist. Dieser Beitrag befasst sich mit Wärmeschutz und Umweltperformance. Ergebnisse des langfristigen Monitorings und weitere wichtige bauphysikalische Aspekte (Feuchteschutz, Bauakustik, Brandschutz) werden zu einem späteren Zeitpunkt behandelt.Wood based curtain wall as a complex task in building physics. The article deals with the development of a systemic solution for replacement of old curtain walls at nonresidential buildings from the sixties and seventies of the 20th century. The main idea was to develop a prefabricated system using modern wood products as an alternative to usual metallic constructions. It is demonstrated that without a complex analysis in building physics and measurements no successful development would be possible. This article is focused on thermal performance and environment oriented assessments, including embodied energy. Results of long-time monitoring and other important topics, like moisture, noise protection and fire safety, will be subject of a following article.
