Advanced control strategies are becoming increasinglynecessary in buildings in order to meet and balancerequirements for energy efficiency, demand flexibility,and occupant comfort. Additional development andwidespread adoption of emerging control strategies,however, ultimately require low implementation costs toreduce payback period and verified performance to gaincontrol vendor, building owner, and operator trust. Thisis difficult in an already first-cost driven and risk-averseindustry. Recent innovations in building simulation cansignificantly aid in meeting these requirements andspurring innovation at early stages of development byevaluating performance, comparing state-of-the-art tonew strategies, providing installation experience, andtesting controller implementations. This paper presentsthe development of a simulation framework consisting oftest cases and software platform for the testing ofadvanced control strategies (BOPTEST - BuildingOptimization Performance Test). The objectives andrequirements of the framework, components of a test case,and proposed software platform architecture aredescribed, and the framework is demonstrated with aprototype implementation and example test case.

organisation, agility, fundamentals, framework, prototypes, organisatie, and wendbaarheid
In our current and turbulent times, it is clear that some sort of organisational agility, in which-ever way achieved, is necessary to survive and thrive as an organisation. The question is how to achieve such manoeuvrability. We propose the use of design (thinking), with a focus on prototyping to iteratively develop greater organisational agility. Based on literature research into the circumstance that drive change, design, prototyping and a number of organisations that seem to have incorporated the right tactics, as well as observations made at a change-programme for a large Dutch corporate, we have developed a model to guide this process. The model proposes that an organisation should focus on developing a shared sense of purpose, to guide all its undertakings. Afterwards, employees should collaborate on iteratively creating the right (digital & physical) environments, culture and personal grounding for them and the organisation, to be able to achieve this purpose. Based on certain (dynamic) criteria and these various domains, personal responsibilities (action agendas) may constantly evolve and keep the organisation agile. This paper explains the reasoning behind the model and calls for further experimentation to take place to verify its effectiveness. LinkedIn: https://www.linkedin.com/in/christine-de-lille-8039372/

Biologically inert elastomers such as silicone are favorable materials for medical device fabrication, but forming and curing these elastomers using traditional liquid injection molding processes can be an expensive process due to tooling and equipment costs. As a result, it has traditionally been impractical to use liquid injection molding for low-cost, rapid prototyping applications. We have devised a method for rapid and low-cost production of liquid elastomer injection molded devices that utilizes fused deposition modeling 3D printers for mold design and a modified desiccator as an injection system. Low costs and rapid turnaround time in this technique lower the barrier to iteratively designing and prototyping complex elastomer devices. Furthermore, CAD models developed in this process can be later adapted for metal mold tooling design, enabling an easy transition to a traditional injection molding process. We have used this technique to manufacture intravaginal probes involving complex geometries, as well as overmolding over metal parts, using tools commonly available within an academic research laboratory. However, this technique can be easily adapted to create liquid injection molded devices for many other applications.

internet of things and open data
Emerging pervasive technologies such as the Internet of Things and Open Data will have severe impact on the experience, interactions and wellbeing of citizens in future smart cities. Local governments are concerned how to engage and embed citizens in the process of smart city development because without them it is difficult for governments and industrial technology providers to understand what future city is desired. We explore how prototyping methods can be used in a multi-helix approach towards a participatory domain in which multiple stakeholders collaboratively envision a desired future smart city. We adopted the different qualities of generative sessions, hackathons and design jams in our method of participatory prototyping for smart cities. Results show that participants appreciate this setting for exploration, experimentation, and making, in diverse teams with members from industry, government, university, and citizens. We will discuss issues for improvement of participatory prototyping to make it more robust for use in urban development processes.
