EuroSun Conference 2010, Graz}, address = {Graz}, organization = {EuroSun Conference 2010}, year = {2010}, abstract = {"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".}, language = {en} } @article{MarszalHeiselbergBourelleetal.2011, author = {Marszal, Anna Joanna and Heiselberg, Per and Bourelle, Julien S. and Musall, Eike and Voss, Karsten and Sartori, Igor and Napolitano, Assunta}, title = {Zero Energy Building - A Review of definitions and calculation methodologies}, series = {Energy and Buildings}, volume = {43}, journal = {Energy and Buildings}, number = {4}, publisher = {Elsevier}, pages = {971 -- 979}, year = {2011}, abstract = {The concept of Zero Energy Building (ZEB) has gained wide international attention during last few years and is now seen as the future target for the design of buildings. However, before being fully implemented in the national building codes and international standards, the ZEB concept requires clear and consistent definition and a commonly agreed energy calculation methodology. The most important issues that should be given special attention before developing anewZEB definition are: (1) the metric of the balance, (2) the balancing period, (3) the type of energy use included in the balance, (4) the type of energy balance, (5) the accepted renewable energy supply options, (6) the connection to the energy infrastructure and (7) the requirements for the energy efficiency, the indoor climate and in case of gird connected ZEB for the building-grid interaction. This paper focuses on the review of the most of the existing ZEB definitions and the various approaches towards possible ZEB calculation methodologies. It presents and discusses possible answers to the abovementioned issues in order to facilitate the development of a consistent ZEB definition and a robust energy calculation methodology.}, language = {en} } @incollection{VossMusallSartorietal.2013, author = {Voss, Karsten and Musall, Eike and Sartori, Igor and Lollini, Roberto}, title = {Nearly Zero, Net Zero, and Plus Energy Buildings - Theory, Terminology, Tools, and Examples}, series = {Transition to renewable energy systems}, booktitle = {Transition to renewable energy systems}, editor = {Stolten, Detlef and Scherer, Viktor}, publisher = {Wiley}, address = {Weinheim}, isbn = {978-3-527-33239-7}, doi = {10.1002/9783527673872.ch41}, pages = {875 -- 889}, year = {2013}, language = {en} }
