Innovative heat buffering in homes

Orange Climate Autarkis is a company with expert knowledge in the field of sustainable housing. It uses Phase Change Materials (PCM) as its “thermal battery”. PCM’s have the intrinsic ability to store and release heat (thermal energy) within a predefined temperature range. Above the upper temperature limit, for example 24 oC, the material melts, absorbing heat, creating a cooling effect on the indoor environment. Below, the lower limit, for example 20 oC, the material solidifies and releases thermal energy, creating a heating effect. After installation the material contributes to stabilizing the thermal indoor environment, reduces the required energy demand for heating and cooling an thereby minimizes the CO2 footprint of the building. PCMs are currently used in floors, walls and ceilings. This limits the amount of PCM that can be made available in a space. In this project we are looking for ideas to increase the size of the “thermal battery” and concepts to place it in a room in such a way that it maximizes thermal comfort. Alternative applications of PCMs in objects that contribute to the interior design of the home are being considered e.g. PCM in design panels or furniture. Issue: in order to effectively contribute with PCMs to a pleasant indoor climate with lower energy consumption, sufficient thermal storage capacity must be provided in a home. This capacity is related to the amount of PCM in the room and the size of the heat-exchanging surface in contact with the environment. Objectives and deliverables: the purpose of this research is to generate ideas for the application of PCMs in products that are used to furnish a home. It must also be made plausible that these ideas provide a feasible concepts. The deliverables of the assignment are: a list of possible ideas, a weighting of ideas against criteria such as attractiveness of use in homes, manufacturability and thermal performance level, development of one or more prototypes of the most promising idea or ideas, the results of a test of this prototype against pre-agreed criteria. The assignment will be carried out by both HAN and Saxion students. It is the intention that both groups stimulate and reinforce each other.

Scaffolding-free building renovation

Traditional renovation approaches for existing residential buildings are to cost and time intensive for large scale application. To achieve the goal of a CO2 neutral built environment by 2050, the production of renovation packages needs to be industrialized and automated as well as its production and installation cost reduced. The aim of different research initiatives in Europe is to investigate how the factory-based prefabrication and installation of renovation packages can be organized. The aim of the INDU-ZERO project, to which your project contributes, is to develop a blueprint (layout) for a factory that can produce renovation packages to renovate 15,000 homes to zero-on-the-meter standard annually for half the costs, namely EUR 40,000 per home. It makes use of a renovation approach in which prefabricated wall and roof panels, the renovation package, are installed onto the outside of the existing walls and roofs, see All servicing technologies are integrated in the panels such as ventilation and heating systems as well as solar panels. The integration requires a structural re-design of the products such as wall and roof panels but also the renovation process at the construction site. With a factory-based production process, the most time intensive task remains the installation process at the construction site, starting with placing a scaffolding (steiger) at the home to be renovated. Whilst the new walls and roofs are assembled and connected in one day, placing the scaffolding takes at least the same amount of time. To further reduce costs and time, the amount of activities at the construction site needs to be minimized. This is why your task in this project will be to develop an installation process which eliminates the need to use a scaffolding for placing the panels. In this project, you will be given the chance to work with Dutch partners of the INDU-ZERO project, such as RC Panels and Buro de Haan. You will engage in desk research, review processes at selected construction sites and develop ideas for a scaffolding-free renovation process. Requested deliverable: 1) a scaffolding-free concept for placing the walls and roof panels that meets the technical and safety conditions and also ensures a reduction of the on-site costs. This can also mean that you give advice on changes in the design of the fixing of the walls and roof panels. 2) a pilot project is planned for INDU-ZERO in Enschede, where the plan is to renovate without scaffolding. Your input and feedback will be used in the preparation of this pilot. You will work on this assignment together with experts from RC Panels (factory), Buro de Haan (engineering office) and the chair Sustainable Building Technology from Saxion.

Biowaste separation in the workplace

Most of the big office buildings do not separate biowaste from the common trash. From a preliminary research with companies in Kennispark Enschede, the reasons for not separating waste are mostly related to the perceived small volume of generated biowaste, inconvenience of having such bin around, the necassary cleaning that it would require and a lack of collection system. It turns out that there is a significant amount of biowaste produced by employees in office buildings and there are two companies willing to codesign the optimal biowaste separation solution for their companies. How are you going to overcome the concerns regarding the biowaste separation? In this project, you’re going to develop and test interventions to persuade employees to separate their biowaste. The interventions need to be organized and tested on location. In codesign sessions you’re going to improve the separation strategy. Possible strategies are gamification, informing on environmental impact, and rewards.

Designing inclusive and circular neighborhoods

The current way of how neighborhoods and residential buildings are being designed and constructed cannot be continued. Society is demanding changes regarding material use, societal inclusiveness and healthy environments. In our view, it is necessary to close material cycles, to connect to a more social housing program and to design healthy buildings that fit within their environment. In this project we want to jointly design an integral circular building for a broad target group consisting of people of various ages and a mixed composition of regular home buyers, tenants and residents with a need for care or assistance. We aim to move towards community-based inclusive housing, because there is a demand for this. It can make healthcare costs manageable and stop the individualization and isolation of people. Simultaneously, we need to consider the immediate living environment this housing provides and to take into account any opportunities the environment provides to contribute to the health and well-being of its residents. The concept of inclusive housing, or inclusion, means that people with disabilities participate in society. In an inclusive society, everyone has the opportunity to participate in a way they desire. Circularity and inclusivity are pre-eminently linked, because people’s needs change over the course of their lives. Since people do not know in advance and cannot know exactly what needs will arise on their personal path or those of their loved ones, flexibility of the built environment is a precondition for enabling inclusive living. This flexibility is also sought within circular construction. The objective for our project is therefore to achieve a well-founded and supported design of a circular inclusive residential building that fits in with its surroundings.
