Namhafte Keynotes, aufschlussreiche Impulsvorträge sowie eine Vielzahl interessanter Workshops: Das war das SDMA2019. Von Building Information Modeling über Fabrikation, Parametrik und Simulation reichten
die Themen bis hin zur Visualisierung und Virtual Reality. Parallel fand an beiden Veranstaltungstagen die umfangreiche Hausmesse mit zahlreichen Ausstellern statt. Es galt das Wissen und die Fähigkeiten aller Besucher
zu bereichern, Neuigkeiten in der Technik zu erkunden und in den Austausch mit Kollegen und Partnern zu treten.
Load Matching and Grid Interaction of Net Zero Energy Buildings. EuroSun Conference 2010, Graz
(2010)
“Net Zero Energy Building” has become a prominent wording to describe the synergy of energy efficient building and renewable energy utilization to reach a balanced energy budget over a yearly cycle. Taking into account the energy exchange with a grid infrastructure overcomes the limitations of seasonal energy storage on-site. Even though the wording “Net Zero Energy Building” focuses on the annual energy balance, large differences may occur between solution sets in the amount of grid interaction needed to reach the goal. The paper reports on the analysis of example buildings concerning the load matching and grid interaction. Indices to describe both issues are proposed and foreseen as part of a harmonized definition framework. The work is part of subtask A of the IEA SHCP Task40/ECBCS Annex 52: “Towards Net Zero Energy Solar Buildings”.
Null-/Plusenergiegebäude - Erfahrungen und Perspektiven zu klimaneutralen Gebäuden in Deutschland
(2011)
The energy topic has become increasingly important in architecture: since buildings are big consumers of energy and architects and the public are interested in energy as never before. [Scognamiglio 2008] The Energy Performance of Building Directive (EPBD) [EU 2010] establishes that starting from 31st December 2020 all new buildings have to be Nearly Zero Energy. The main architectural implication for this condition is that if up until now the domain of design was the building itself, now it is the building and possibly other spaces, that have to be conceived for placing the energy generation devices. Photovoltaics (PV) is particularly suited for reaching the (Nearly) Net ZEB status, due to its technical features, the existing knowledge on how to use PV in buildings, and since it is the easiest and most reliable way to get the (Nearly) Net Zero Energy objectives. [Torcellini 2006] A relevant international effort on the subject of the Net Zero Energy Buildings (Net ZEBs) - Net ZEB meaning that the buildings are connected to an energy infrastructure - is ongoing in the International Energy Agency (IEA), joint Solar Heating and Cooling (SHC) Task 40 and Energy Conservation in Buildings and Community Systems (ECBCS) Annex 52, titled “Towards Net Zero Energy Solar Buildings” [IEA 2008a]. The authors of this paper, all participating in the IEA research group, investigate how the use of PV for Net ZEBs can influence the building’s design, taking into account different building typologies (e. g. new ones vs. existing ones, listed buildings, etc.). Similarities and differences between PV and Solar Thermal (ST) are discussed, too. The paper results in defining some architectural issues for using PV in NZEBs design, which implie to re-think the way buildings are designed.
