Editor's Notes
- First of all thanks a lot for selecting our project „Energy efficient upgrade through intelligent system networking“ to be presented here in this working group. We really appreciate the opportunity to take an important step to get closer to the whole International Sustainability Campus network.
- Holistic Campus Planning at Technische Universität Darmstadt got some new impacts within the last months… in so far as the subject energy and sustainability is tackled more specifically and diversified, too. We are aiming to anchor it on all levels and fields of action of our University to uncover the already existing energy competences, which we definitely have in the field of research but which are not really visible – neither internally nor externally. The first small but quite important step towards this necessity to somehow unite all compliant activities were taken by the meanwhile retired Professor of Architecture Manfred Hegger, who was an highly active architect and researcher in the field of energy efficient building design and maybe known by some of you through the Solar Decathlon successes in Washington DC in 2007 and 2009. So you see…. The first steps are a little while ago… but „a good thing takes some time“ and so it is only two weeks ago that my colleague and me were able to establish the project office for the “sustainable Campus Lichtwiese”. And the official kick-off project of our office-work is the one I want to present you during the next 10 minutes.
- The project focuses on the technical potentials of a holistic campus planning – and within the first period of 30 months it focuses on the conception of this planning. The subsequent implementation is intended but we need to apply for a further project. The main idea is, to design one possible way towards implementing the turnaround in energy policy within a smaller urban context. The goals of the German energy policy are set for the year 2050 and within the project we will try to achieve these goals until 2030. Therefore the Campus Lichtwiese – that you can see on this aerial photograph – has been chosen, as it is particularly well suited as a research object. The Campus provides perfect conditions for an analysis of the potentials of energetic networks. They are… It is a spatial entity (that you rarely find in a comparable urban context) and as you have seen on the photo there is Campus and all around only green…In this regard it is important to consider the potentials of the surrounding landscape for micro-climatic uses and for the integration of renewable energy production or even its storage. It has one exclusive proprietary (the University itself what brings some important administrative advantages) It has an autonomous energy-supply by a local block heat and power plant There is a diversity of users (characteristic Campus-uses like offices, laboratories, lecture halls, a canteen and libraries on the one hand but also production-related experimental halls, kindergartens or even upcoming residential uses) this concentrated multi-functionality is a pre-condition for an exemplary inspection and facilitates that the results of the project may be transferred to bigger urban contexts in the future
- What we also find is a nationally and internationally representative type of University and Science Campus’, that was evolved in the middle of the last century ---- and subsequently… as time went by… There is a considerable need for restoration and redensification of the existing buildings and infrastructure In fact… the Campus is changing continuously. Buildings from the 1970 have been restorated in whole or in part, others – like the listed building of the department of architecture that you can see on this photograph – will be restorated during the next years. In a word there is a lot of work to do to finally have a modern Campus providing comfortable and sustainable working, research and study places on all levels…
- So to make the first steps, data representing the status quo at Campus Lichtwiese need to be acquired to subsequently evaluate given potentials. The main focus is set on electrical and thermal energy supply and the buildings themselves. The key to constantly increase energy efficiency is the reduction of the total energy-use going hand-in-hand with the reduction of carbon emission and simultaneously cutting the energy import from the public grid. The actual situation is as follows… The Campus has an own heat power plant, built in 2001. A 14 kilometers long district heating system from the 1970s supplies the heating demand of the entire University and even other buildings in the city like a swimming hall for example. This power plant is only heat-driven, so electricity is only a side-product of heat-production, what means that on warmer days there is not enough electricity provided. Still 25% of the whole electricity demand must be bought from the public energy provider. On top, due to some new buildings on the Campus, especially a high-performance computer center the cooling demand increased significantly. So actually the construction and the integration of a cooling network is checked within a next step we will analyze if the intended cooling system, which will be responsible for a huge part of the energy consumption, can be used as thermal storage, too.
- The design of an overall energy conception requires an exchange of roles. So we need to ask which kind of constructive and technical measurements do we need to improve buildings with regard to the interconnection of thermal and electrical systems? And we need to ask, how to integrate the constructed surrounding in future energy supplying systems not only as consumers but also as energy sources and storages. Each building shall use, deliver or store some kind of energy and thus become an active participant within the system, that in turn shall be supplied on the one hand by a variety of energy plants and on the other hand by recycled energy from the active participants. By that the remaining energy import from the public grid will be reduced to a minimum level – maybe zero – which means that in future the University aims to be energy self-sufficient.
- This idea isn’t that new and wouldn’t be eligible for promotion as efficiency-enhancing instruments and tools are quite well-known today. But beyond we want to build up an intelligent and comprehensive adjustment and interlinking of measurements. We need models to simulate the potentials of the whole system and its players in order to design a self-regulating energy Campus, which acts like an autonomous system. Based on an extensive sensorial communication network between buildings, thermal and electrical grids the system becomes able to actively regulate the energy flows on the Campus. Information of sensors and actuators can be gained and distributed accordingly. By integrating innovative grid-components and operation modes the extent of the system’s constructive expansion and subsequently the costs of this innovative project can be reduced. In this context one final target is also to establish an on-going energy monitoring system to also better control the system’s optimization potential.
- But prior to all sensorial communication we will need real communication… Indeed, the required simulation models are complex and to keep or first to make them running the competences of electrical engineers, architects, mechanical engineers and computer scientists need to be combined within the whole research project. The trans-disciplinary and trans-technological approach is a huge challenge – not only technically or structurally but also and particularly socially. There is the urgent need to understand that different disciplines work successfully only if strategies build upon and complement each other. Our project aims to demonstrate this necessity without neglecting the importance of one single discipline. In this regard the project is an object of study, a suggestion for imitation and further development as well as a multiplier for different urban models, typologies and industries.
- And for further steps we hope to get inspired by all the other wonderful projects which are presented here within this conference! thank you… and if there are any questions… please!
- Besides this technical approach, we started to implement the ideas of a holistic Campus planning on other levels, too. The different ways towards a sustainable Campus need to be anchored in research and construction but furthermore and maybe especially in the university‘s public and in its internal and external communication strategy. Therefore we participate at the ECHO-project that wants to establish „energy-saving-campaigns“ at ten German Universities in order to support an sustainable energy user‘s behavior. A strategy will be developed to support the university‘s key players in promoting and anchoring climate action projects. Workshops will be offered to qualify at least those key-players to so called „change agents“. Those will attend and expand the ideas of this campaign and furthermore initiate new sustainable changing processes. Also in cooperation with our students it is intended to build up an appropriate public online-tool to make the projects results available and adaptable for other interested Universities. And for further steps we hope to get inspired by all the other wonderful projects which are presented here within this conference!
