PhD and MSc students workshop
During the During the C24 / ECBCS Annex 49 conference ‘The Future for Sustainable Built Environments with High Performance Energy Systems’ a parallel workshop will be organised for PhD and MSc students. The scope of the workshop is directly related to the conference theme. Next to it, the workshop has three specific objectives:
1) Obtaining the students’ vision on the conference themes:
The field of energy transition is new and challenging. It requires a multi-disciplinary and integrated approach to come to a balancing between the supply side (renewables and low valued energy sources) and the demand side (energy efficient buildings and communities). Therefore the conference does not only focus on the state of art of current research and engineering solutions but also on new and innovative ideas from MSc and PhD students. At the end of the conference the students’ visions and ideas are compared with the thesis and conclusions of the conference presentations.
2) Obtaining input for the CostEeXergy project:
The main objective of the CosteXergy project is to broadly disseminate new knowledge and practical design-support instruments that can facilitate practical application of the exergy concept to the built environment. In order to achieve this objective, the Action relies on research activities carried out by its members, which focus on investigating and demonstrating how exergy analysis can be used in the development of innovative insights and concepts and support a wider deployment of low-valued heat and other renewable energy sources. During the conference some students from the CosteXergy group will discuss the conference themes to give more input to the final report.
3) Obtaining input for the new European IEE project ‘IDES-EDU’ (Master and Post Graduate education and training in multi-disciplinary teams):
There is currently a substantial need for practitioners like architects and engineers to be specifically trained and educated in the integral sustainable design approach and who work in integrated multidisciplinary teams, addressing the integration of sustainable energy in buildings and built environment in general and as imposed by the EU in its policies. The newly started IDES-EDU project intends to educate, train and deliver such specialists, both students and professionals working in the building sector. Within the project a number an educational modules and curricula will be developed. We hope to obtain some recommendations from the students for the development of the curricula and for the continuation of the IDES-EDU project.
During the workshop the students will work in three groups, each addressing a theme, parallel to the conference programme:
Group I: Methods and Design
Group II: Buildings
Group III: Communities
For each group will work on a number of questions. One (or more) questions will be posed by the conference organisers; at least one question or problem can be formulated by the working groups. Each group will have a moderator.
Group I: Methods and Design
Moderator: Prof. Masanori Shukuya
In the design of high performance built-environment, the starting point is to understand the relationship between thermal characteristics of occupants’ body and their surrounding space. Please raise the basic factors related to thermal characteristics of the human body from the aspects of thermal physics, physiology, psychology, and behaviour science as much as possible.
What kind of thermal characteristics of building envelope elements do you think necessary to meet the thermal characteristics of the human body? Please raise these elements as much as possible. Think these from the viewpoint of passive and active technologies and also from the requirement of heating, cooling, lighting, ventilating systems.
Please make connections between the basic factors of the human-body and the building envelope elements.
Group II: Buildings
Moderator: Prof. Prof Gudni Johannesson
Towards 0 energy buildings electricity use for lighting, fans, and especially household and office appliances is becoming more and more dominant.
One of the possible strategies for a further reduction of total energy demand, especially in residential buildings is the application of Building Bound appliances instead of Household appliances. Examples of existing technologies are hotfill washing, drying etc., central vacuum cleaning.
What is your opinion about these developments? Is it feasible concerning economics, acceptation by end-users?
Does this make any sense or should we look to alternatives (for example central laundry facilities instead of individual washing).
Do you see any possibilities for cold fill appliances?
Do you see any possilities for an exergy approach to tackle this problem?
Group III: Communities
Moderators: Peter Op ‘t Veld/Christina Sager
Energy systems on a community scale are very promising for the large scale application of renewables.
Locally available sources can provide sustainable heat, cold and electricity.
Therefore, often an (new) infrastructure is required and the buildings need adaption to a certain extent.
District heating and cooling is the most likely application, eventually combined with polygeneration from several (renewable) energy sources.
What’s the role of municipalities on the one hand and the traditional energy companies on the other hand?
Who should be involved else?
What determines the optimal size of such communal system?
Low temperature energy sources like groundwater are a kind of half-fabricate and often need post processing at some moment.
What systems can you think of?
What is the use of the exergy approach in this? How to reduce exergy losses?
What is the role of the Trias Energetica in this?
System boundaries play an important role: optimisations on macro level (DH&C level) may be unfavourable for a individual client (end-user) and vice versa.
How to find an technical, legal and financial optimum, which satisfies both the energy supplier, energy-user and (optionally) the grid administrator?
What kind of demand-side management can you think of?
How would you allocate the CO2-credits between the energy-supplier and energy-users?
