Inhaltsbeschreibung

This workshop in Vienna is organized in the run-up of the 5th working meeting of the IEA EBC Annex 67 Energy Flexible Buildings in Graz. It aims at bringing together international experts and the Austrian building and demand response community for know-how exchange and discussion on the topic of energy-flexibility in buildings and its role for smart grids. The focus will be on thermal and electricity based flexibility potential of buildings and practical experience with first implementations and demonstrations.

Heating and electricity consumption on demand – at building level

This event is one in a row of the City Of Tomorrow in Practice workshops, where relevant research and development results are presented and discussed with experts and professionals. Along the City of Tomorrow programme of the Austrian Ministry for Transport, Innovation and Technology, new technologies and innovations should pave the way for an altered understanding of future working and living within cities in combination with mobility and production, making cities an attractive place to live while being energy efficient at the same time.

In the future, the high share of renewable energy sources in electrical power and district heating grids will force the transition from a purely demand-oriented energy production ("generation on demand") to a production-oriented demand respectively consumption ("consumption on demand"). This is also rational and necessary for the promotion of more accurate direct use of short-term predictable yet not time-controllable renewable energy production from e.g. wind or solar power, as well as solar thermal systems. It will relieve the grids and storage requirements likewise.

The adaptability of buildings to currently available energy supplies, their "energy flexibility" in respect with load balancing of the grid, is hard to quantify at this point in time. Indicators and a methodology for quick characterization of a building regarding such flexibility do not exist. The potential for energy flexibility in buildings is determined by factors like heat storage capacity of building components, quantities and sizes of thermal storage tanks and batteries, quantities and type of electrical devices and consumers such as heat pumps, the specifically utilized control systems, and similar.

Intelligent use of related equipment enables to shift peak loads and discharge the grids at the right time. In this spirit, buildings could be intelligent "prosumers" (consumers AND producers of energy). The aim of the EBC Annex 67 is to evaluate, analyze and characterize this future role of energy-flexible buildings integrated with renewable energy systems. Ongoing studies in the field will be presented and discussed.
