  1. Bed-Load Diversion with a Vortex Tube System 

    Rachelly, Cristina; Albayrak, Ismail; Boes, Robert M.; et al. (2019)
    Impaired sediment connectivity in river systems due to transversal hydraulic structures is a primary cause of channel narrowing and down-cutting, as well as reduced morphodynamic variability. Among various restoration measures, the vortex tube is a structural measure to re-establish bed-load conveyance during flood events at low-head hydraulic structures. Bed-load particles are entrained through a slit in the tube soffit and sluiced from ...

    Hollberg, Alexander; Lützkendorf, Thomas; Habert, Guillaume (2019)
    Proceedings of the 2019 Sustainable Built Environment Conference (SBE19)
    The use of Life Cycle Assessment (LCA) during the design phase can help to improve the environmental performance of buildings. However, designers and clients find it difficult to set environmental performance targets and interpret the results obtained through LCA in order to improve the building design. Therefore, performance levels or benchmarks are needed that provide design guidance towards reducing the environmental impacts of buildings ...

  8. Butt-joint bonding of timber as a key technology for point-supported, biaxial load bearing flat slabs made of cross-laminated timber 

    Zoellig, Stefan; Muster, Marcel; Themessl, Adam (2019)
    Proceedings of the 2019 Sustainable Built Environment Conference (SBE19)
    An efficient butt-joint bonding technology allows to build new types of timber structures. Under the name Timber Structures 3.0 a connection has been developed which connects timber elements with an end-grain to end-grain butt joint bonding. Therefore, it is now possible to build continuous, point supported flat slabs in cross laminated timber (CLT). Multiple CLT slabs are connected rigidly together and are only supported by columns. Some ...

  9. Probabilistic LCA and LCC to identify robust and reliable renovation strategies 

    Galimshina, Alina; Hollberg, Alexander; Moustapha, Maliki; et al. (2019)
    Proceedings of the 2019 Sustainable Built Environment Conference (SBE19)
    Buildings are one of the largest energy consumers and greenhouse gas emitters in the world. As the largest part of the energy consumed by the existing non-insulated buildings occurs during the operation stage, retrofitting the building stock is crucial to reduce the environmental impact. To guarantee that the retrofit measures provide economic and environmental benefits, the whole life cycle should be assessed. However, the identification ...

  13. Consistent BIM-led LCA during the entire building design process 

    Cavalliere, Carmine; Hollberg, Alexander; Dell'Osso, Guido R.; et al. (2019)
    Proceedings of the 2019 Sustainable Built Environment Conference (SBE19)
    Life Cycle Assessment (LCA) is a suitable method to analyse the environmental impact of buildings' design choices. However, the nature of the building design process leads to a dilemma when applying LCA in early phases. LCA can be fully performed only in the later design phases when complete information is available, but it is too costly to make changes. As a result, LCA is scarcely employed as a decision-making tool. Building Information ...

  15. Energy transition and technical energy regulations in the building sector 

    Knoeri, Christof; Schwarz, Marius; Nakhle, Christina (2019)
    Proceedings of the 2019 Sustainable Built Environment Conference (SBE19)
    Energy demand from buildings accounts for about 31% of global final energy demand and 23% of global energy-related carbon emissions. Technical energy regulations or building energy codes - policies that set minimum requirements for energy in buildings – have proven effective and efficient in decarbonizing the building sector. However, despite their long history and success, policymakers increasingly recognise that TERs in their current ...

    Basic, S.; Hollberg, Alexander; Galimshina, Alina; et al. (2019)
    Proceedings of the 2019 Sustainable Built Environment Conference
    Life Cycle Assessment (LCA) has become a widely accepted method for environmental assessment of buildings, but is still not commonly applied in design practice. The biggest potential for optimization and reduction of GHG emissions lies in the early stages of the design process. Therefore, a design-integrated approach for LCA is needed. The goal of this paper is to describe the development of a parametric LCA tool for application in early ...
