Performance & Embodied Energy

The German Government has specified the goal to reduce the energy demand to 50% of that of 1990 by the year 2050. Hereby, private households account for 38% and the industry for 40% of the overall energy demand; highlighting the relevance of research activities in these areas to reach this goal. It is becoming increasingly important to shift the focus from individual disciplines toward a holistic view and an interconnectedness between various disciplines in order to analyse and exploit comprehensive effects.

ETA: Energy efficiency, technology and application centre

The aim of the project is to enable energetic networks in addition to energetic improvement in order to feed back inevitable waste heat into processes with energy demand. Besides production equipment, this takes into consideration the machine periphery, building services and the factory building.

Innovative facade elements based on ultra-high strength concrete and aerated concrete are developed and thermally activated with capillary tube matting. Next to energy efficiency, special focus lies on the life cycle cost of the elements. Using a single-material layered concrete construction features good recyclability.

EnEff:Stadt SWIVT Components for existing housing settlements – Impulses to connect energy efficient technologies

Modifying and maintaining existing structures as well as the design and creation of new buildings has a long-term effect and great influence on the future usage of our resources. Therefore, it is very important to reduce the energy consumption of buildings throughout their entire life cycle.

Intelligent coupling of different forms of energy, storage technologies and network infrastructures allows for efficient use of synergy effects as well as fine tuning energy production and energy use in an optimum manner.

Due to the complexity of holistic approaches when linking individual energy sensitive technologies, there is a great demand for interdisciplinary research. This research aims at using a real settlement to develop a concept that improves the energy balance of the settlement by at least 30% compared to conventional renovation. The approach to solution plans to compact the existing settlement with an energy positive component. The energy balance of the settlement is significantly improved by means of electrical and thermal storage systems while minimising intervention of the existing buildings.

A close cooperation with the developer and the energy supplier allows for a conception based on true usage and load data as well as existing data.

EnEffStadt: SWIVT II Pilot project

In the follow-up project SWIVT II, the strategy developed in the apron project for linking building concepts in networked operation with operation-optimised, innovative energy technologies at settlement level in the Postsiedlung quarter in Darmstadt will be implemented and demonstrated in practice.

After successful verification of the SWIVT approach by theoretical and experimental investigations, prototype construction and coupled simulations, the project partners want to validate the effectiveness of the approach solution at system level in all its partial aspects. Both models from SWIVT (e.g. as application tools for the design of energy storage systems) are transferred into practice and the concept of an existing housing estate as an energy-efficient, system-oriented unit is implemented and validated.

SynErgie

The future electricity system in Germany will be strongly influenced by the energy transition. Due to the increasing share of renewable energies and the associated fluctuations in electricity generation, solutions must be developed that stabilise the electricity grid, i.e. bring electricity consumption into line with electricity generation. In this case, the SynErgie project aims to research and demonstrate how energy-intensive production processes can be adapted to fluctuating power supplies in order to make a contribution to the success of the energy transition. In addition, this will create the conditions for Germany to become the leading provider of new technologies and processes that link energy-intensive, individualized industrial processes with the volatile feed-in of renewable energies.
