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”.
“Net Zero-Energy Building” has become a popular catchphrase to describe the synergy between energy-efficient building and renewable energy utilisation to achieve a balanced energy budget over an annual cycle. Taking into account the energy exchange with a grid overcomes the limitations of energy-autonomous buildings with the need for seasonal energy storage on-site. Although the expression, “Net Zero-Energy Building,” appears in many energy policy documents, a harmonised definition or a standardised balancing method is still lacking. This paper reports on the background and the various effects influencing the energy balance approach. After discussing the national energy code framework in Germany, a harmonised terminology and balancing procedure is proposed. The procedure takes not only the energy balance but also energy efficiency and load matching into account.
Null-Energie-Häuser
(2010)
Die Begriffe „Nullenergiehaus“ oder „Plusenergiehaus“ sind in den letzten Jahren national und international zum Inbegriff für die konsequente Zusammenführung von Maßnahmen zur drastischen Energieeinsparung und optimierter, dezentraler Nutzung erneuerbarer Energien geworden. Dabei geht es nicht um energieautarke Gebäude und die dabei große Herausforderung der saisonalen Energiespeicherung. Grundidee ist, dass die von einem Gebäude in ein Netz eingespeiste Energiemenge in der Jahresbilanz mindestens dem Energiebezug entspricht. Sowohl im Kontext der Fortführung der europäischen Gebäuderichtline als auch im aktuellen Energiekonzept und Energieforschungsprogramm der Bundesregierung wird das Thema besetzt.
