The Energy Supply of Campus using Exergy Approach
Gommans, Leo Sustainable Building Research Center 2011 International journal of sustainable building tech Vol.2 No.2
Xperience Parkstad is a district in Heerlen (The Netherlands) where several schools are located; the campus. This district consumes a considerable amount of energy and wants to reduce 80% of the $CO_2$-emissions by 2025. The easy to implement measures to reduce the $CO_2$-emission have already taken place, meaning that more drastic measures are necessary, while the solutions are not only found within the buildings themselves. Besides reduction of the energy demand, 10 percent of the electricity production will be realised with photovoltaic cells and small wind turbines. The remaining electricity and heat demand will be generated from biomass. The plans for the energy supply of XperienceParkstad are elaborated in an energy vision for the district [2]. Further research into the possibilities for a $CO_2$-neutral energy supply with biomass, Combined Heat and Power (CHP) is done by Cauberg-Huygen Consulting Engineers in Maastricht [3]. Although we try to solve the energy supply $CO_2$-neutral, this does not mean that it is an optimal solution from an exergetic point of view. Biomass resources are limited and should be used as effectively as possible. Exergetic considerations play an important role in the search for optimal solutions of the energy supply for the Xperience Parkstad district. The idea behind the exergy approach is to use the available energy flow as effectively as possible, by matching the quality of the required energy, as much as possible to the quality of energy available. To maximise the use of biomass i.e. apart from energy conversion, energy storage and transport is an important aspect for the design of the energy supply, as will be explained subsequently in the paper. By taking advantage of the local potentials, existing energy networks in the area and the old mine galleries can be developed, optimising the use of biomass as an energy source. The local situation provides old mine shafts that are filled with water. They could be used for cooling and storage of residual heat. This paper describes the plan and considerations invoved in the search for exergetic design solutions for a sustainable energy supply in the region Parkstad, which goes beyond solutions on the building level and the district Xperience Parkstad.

Urban Harvest + Approach for 0-impact Built Environments, Case Kerkrade West
Rovers, Ronald,Rovers, Vera,Leduc, Wouter,Gommans, Leo,Sap, Herwin,Van Kann, Ferry Sustainable Building Research Center 2011 International journal of sustainable building tech Vol.2 No.2
The need to restructure our society into a sustainable society has been recognised by many, though a clear direction and ambition in this process usually fails. At the Research Institute for the Built Environment of Tomorrow, RiBuilT, the definition of a sustainable society has been summarised as the 'Concept of O': O for a circular approach of resource management, and 0 (zero) for 0-impacts of our activities; 0-energy, 0-materials, 0-water, 0-landuse and 0-air (pollution). In order to apply this approach to existing urban environments, the Urban Harvestplus approach was developed. This paper will analyse the first test results of the actual implementation of this approach on the Dutch district of Kerkrade West. The pilot on Kerkrade West shows that even when the production of resources is maximised and the demand for them will be drastically reduced, it will still be hard to achieve the 0-impact state. We need new and more innovative solutions to actually make it happen. However, the Urban Harvestplus approach proved to be a straight forward approach in getting closer to the zero-impact situation. It also clarified the interaction between resources and made clear that resource cycles should never be considered on their own, but always in relation to each other to avoid sub-optimisation. Many questions and areas are left for further research, but we believe Urban Harvest-plus represents a strong basis to depart from.
