Moss covered surfaces are a promising way to mitigate the urban heat island effect. A layer of moss on a building’s façade reduces heat absorption during summer, hence passively cooling the building and its surroundings. The startup Respyre wants to offer such moss layers as a commercial product. A bio-gel mixed with moss fragments is sprayed on a porous concrete outer layer. This is irrigated for several months until the wall is covered by a layer of living moss.

The aim of this project is to rethink the existing irrigation system, since it gives a bad water distribution, resulting in high water usage and uneven moss growth.

First, the context was analysed. Literature study and an interview with an expert provided a better understanding of what role moss has in mitigating the urban heat island effect and what moss needs from a biological perspective. Further research revealed what solutions for providing moist already exist. A stakeholder analysis provided insight into who has something to say about the irrigation system. All these findings together resulted in a list of requirements.

During a brainstorm, a set of ideas was sketched to find as many out-of-the-box solutions as possible. This is a mix of new ideas, existing ideas found during the analysis, and combined ideas.

The brainstormed ideas that are feasible were developed into concepts. They were prototyped and their water distributing performance was tested by irrigating them in a green house. The concepts have been assessed on (among others) water distribution, estimated costs, minimum water pressure, ease of installation, and the need for developing new parts.

Five promising concepts were further developed and tested on a larger prototype. Their water distribution was quantitively tested, and costs estimated.

The finally chosen solution was further improved and detailed in the last stage. The end result is a design and prototype of an irrigation system that gives a slightly more uniform water distribution at a significantly slower rate for comparable costs.

Context
The topic of this graduation project is sustainable mobility. Sustainable mobility in urban areas can be achieved by using active transport. Cycling and walking is called active transport and is sustainable due to the lack of emissions. Passive transport such as cars and pedal bicycles produce a lot of emissions, which are bad for people’s health and the climate.

Advier, the client of this project, is a consultancy working on innovative and sustainable mobility. Together, we looked at the future of mobility inside the city. How to make a green world in 2040.

Aim of the project
To design for the year of 2040, first I researched what the future will look like. A future that is as green as possible through technological but also behavioural developments. To eventually move towards this green world, the following research goal was drawn up: Design a service to encourage more sustainable mobility in and around urban areas in 2040.

To accomplish this goal, the research through design method was applied. For the three different phases, this design method was applied in an exploratory way. As a result of the analytical, conceptual, and conclusion phases, a service was designed. This service, called Mobi, will motivate people to use more sustainable mobility and inspire sustainable mobility projects.

Analysis
Throughout the project, I built on a strong foundation of background knowledge. This knowledge was built from literature research and was built up from three topics.

Mobility
This chapter has looked at present and future mobility. The impact of mobility on behaviour, rearranging mobility inside the city by giving priority to cyclists. By looking at this development of mobility, means such as electric vehicles and low-traffic cities seem to be the solution, but I believe the solution lies mainly in changing people’s behaviour.

City
The city adapts to mobility and vice versa. How differently a city functions when a 15-minute city philosophy is applied. It is important to take the city into account when designing for it. How communities emerge and streetscapes change will influence the criteria for designing a future-proof service.

Future visions
What the future will look like no one knows, but by looking at the extremes of future worlds, design possibilities will emerge. By taking a green world as a starting point, the service created within will lead to a more sustainable world. Thus, this project is focused on making a green world a reality.

Concept
To come up with the broadest possible solutions for the project, behavioural change was researched. To practice sustainable behaviour, you do need to know how sustainable behaviour looks like and, more importantly, what it does not look like. There is demand for more knowledge around mobility emissions, research has shown. To create a green world, it has to be clear how we get there. That is why Mobi has been devised that will ensure a green world for the future.

Conclusion
The Mobi service consists of three elements: bike, car and overview. For each element, I looked at providing the necessary information on sustainability and investigated what the appropriate form of communication would be. In this way, Mobi primarily offers a form of information to the user. The communication is in a playful way to keep the user motivated and make more use of active transport.

Towards the end of the project, the designed service proved to be most suitable for an application for the smartphone and a implementation of an existing mobility provider. It will be deployed in combination with vehicles and technologies. The service was also tested among users and experts in the field of mobility and MaaS; Gaiyo, Advier and SJEES. This evaluated the service as an inspiring resource for future mobility and possibilities for implementation.

Today, an increasing number of art, history, and culture-related items are being digitally reproduced and displayed by cultural heritage institutions on websites. As the digitisation of cultural collections progresses, digital collection websites are reaching a broader and more diverse audience, including a growing segment known as casual users. This user group is becoming more prevalent in the context of digital collections. However, despite their increasing presence, the current interfaces of most digital collection websites do not adequately support the casual user experience. Casual users typically visit these sites without a specific informational goal, preferring exploratory browsing. In contrast, many existing interfaces are designed for users with clear motivations, focusing on targeted searches. Tools like search bars and catalogues may limit exploration for casual users, who may feel less encouraged to explore freely. This raises a critical question: how can we design an innovative exploration experience that invites casual users to explore and supports their divergent exploration?

Through a literature review of psychological theories on exploratory behaviour, design principles for supporting casual users, theories on facilitating serendipity, and user research with six casual users, a deeper understanding of the context was gained, leading to the definition of the design goal. Four interaction qualities—exploratory, serendipitous, supportive, and playful—were then established as guiding principles for the project.

Based on the research findings, four initial concepts were developed and tested with nine participants. Insights from the first round of testing were used to formulate an integrated concept. An interactive prototype was then created to conduct a second round of testing with five participants.

The final concept, Wander More, is an innovative online tool for exploring digital collections. It is designed to invite casual users to wander through diverse cultural items using connected keywords in a simple, playful, and surprising way. The key features of the final concept are as follows:

1. Wandering through various items via keyword connections in a simple and endless way.
2. Playfully dragging keywords to generate a diverse range of surprising items.
3. Viewing exploration journey summary
4. Also supporting deep and specific exploration

In the final evaluation, the design was assessed to determine how well it achieved the design goal. Five participants found it to be a simple and enjoyable experience that allowed them to explore diverse items in a playful and surprising manner.

In this report you will read about the design of the Codex Bonaire, an engine room experience design of the Bonaire. The Bonaire is a steam powered sailing ship being renovated in Den Helder to be a museum. This project is focused on creating an experience in the engine room that visualises the engine room without building it physically. The design is meant for school groups of 12-14 years old, 14 students each. The Codex Bonaire comprises mostly of four interactive installations that tackle the different pieces of information that are essential for the Bonaire’s heritage. The different installations also cater to different visitor’s interests: Physical activity, competition, creation and visual beauty among others. The installations have a coherent embodiment styling, as well as a coherent digital interface and similar interaction throughout.
The rest of the room also contains other elements that increase the immersiveness of the whole experience, like stickers that simulate looking outside the ship, and an authentic telegraph that visitors can try getting orders from.
