Anticiperen versus improviseren: Over recyclebaar bouwen en hergebruik
No full textWhen the SS Normandie was launched in the early 1930s, it was one of the most famous and most luxurious ships of its time. In the end it would only serve as a passenger liner for six years. During the Second World War the US Navy appropriated it for use as a troopship. The ship was crippled by suspected sabotage in 1942. Shortly after the war, a mere 15 years after it had been launched, the ship was taken apart and the steel recycled. The luxury interiors were removed; the doors, the furniture and thousands of parts of the SS Normandie were scattered all over the world. This dismantling did not mean the ship was destroyed; pieces of it survive in countless cities, hotels, churches and homes.The status of architecture is different from that of shipbuilding; in the collective consciousness it is of another order entirely. Demolition is destruction and the mere announcement of demolition often elicits violent reactions. The question is whether this is always a good thing. Would it not be better for some buildings, however beautiful they once were, to be disassembled into elements for reuse? The pragmatism of shipbuilding can improve the functioning of our cities. It would present opportunities for a unique, new architecture if we showed more daring in slicing into, hollowing out or upending the existing built environment. Reuse of existing structures, and certainly of landmarks, requires a lot from designers, but it can lead to startling, strange and exciting proposals when the dismantling of elements becomes an option.Anticipation versus improvisation contrasts design for disassembly, in which a second life for construction materials is anticipated from the outset, with reuse, in which second-hand materials are used for construction. Both approaches centre on the process and not the final design. They therefore do not generate new styles or aesthetics, but rather dismantlable prototypes and unexpected architectural improvisations. The motivation for reuse and design for disassembly is the necessity for a more frugal use of materials. Not just to prevent the production of waste material, but also because of the impending shortage of raw materials.Teachers of Practic
People want to press the button themselves; interview
No full textPeople can be strange creatures, as ergonomics expert Professor Peter Vink (Industrial Design Engineering) knows. They will sit in tight and uncomfortable seating to save money, complain about it in surveys and then do it all over again. These are the enigmas of environmental ergonomics.Delft University of Technolog

Comfort
No full textStreven naar comfort of het tegengaan van gebrek aan comfort (discomfort) kan de samenleving veel geld schelen. Comfort is geen luxe. Het is riskant te vertrouwen op ontwerpen die worden aangeboden onder het motto van comfort. Ontwerpers en ergonomen kunnen een unieke aanpak bieden waarin aangetoond wordt hoeveel mensen het product comfortabel zullen vinden. Spreker pleit voor meer kennis aangaande discomfort toe te passen in participatief ergonomische ontwerptrajecten. Ook is nieuwe kennis nodig over de relatie tussen beleving en comfort. Dit kan aan de hand van experimenten waarin vanuit de doelgroep over een zo reëel mogelijke situatie gerapporteerd wordt over comfort
A larger statistical basis and a wider application area of a re-derived PPD equation in the (NEN-)EN-ISO 7730 model
No full textThis paper has the objective to initiate a discussion on potential improvements or extension of the validity of the original equation of the Predicted Percentage of Dissatisfied (PPD), according to (NEN-)EN-ISO 7730. This paper is to be regarded as a supplement to a paper on a re-derivation of the PMV equation in the Fanger model (Roelofsen, Jansen, and Vink 2021). In practice, in scientific research it regularly appears that the PMV (Predicted Mean Vote), and by extension the PPD, are applied outside the range based on which the PMV and the PPD equation are derived. In practice, this can occur, for example, in the evaluation of the measurement or calculation of temperature exceedances in a room, for sedentary activities. As it turns out, a PMV equation with an application of −3 to 3, for at least sedentary activities, would be useful in the different fields of study. For that reason, Roelofsen has adapted the PMV equation in the (NEN-)EN-ISO model. But to what extent should the PPD equation also be adjusted? After all, the PPD is also derived from and limited to a PMV of −2 to 2, according to (NEN-)EN-ISO 7730.Emerging MaterialsMaterials and Manufacturin
Towards comfortable communication in future vehicles
No full textThis research aims to study the effect of seat and/or backrest rotation on comfort and quality of conversation. Different sitting arrangements were tested to study the effect of the seat layout on: 1) (dis)comfort experience; 2) conversation quality and 3) postures. Two seats were arranged in different angles (0° 45° 90° and 180°) at the same distance (1 m) and participants were asked to talk to each other. The participants’ postures were acquired by using cameras and markers on the participants’ body. Questionnaires were used to rate the perceived (dis)comfort and quality of conversation. Results show that 90° configuration scored the best both in overall comfort and quality of conversation; while the 0° configuration scored the lowest in both ratings. A strong correlation was established between high comfort and good quality of conversation.Accepted author manuscriptApplied Ergonomics and DesignMechatronic Desig
Visie op de waarde van het gebouw van Bouwkunde voor de campus
No full textDe TU-campus is in de loop der tijd letterlijk en figuurlijk verschoven van universiteit in de stad, naar een ‘enigszins zelfstandige sector’ (Van de Broek, 1971) en vervolgens naar een letterlijk klassiek campusmodel (gebouwen in het veld) ten zuiden van de Kruithuisweg (fig. 1). Deze ruimtelijke visies volgden het veranderende programma, de ambities van de universiteit en invloeden van buiten. De sporen van deze ontwikkelingen zijn zichtbaar in de oude binnenstad tot aan de stadsrand in Zuid. In dit essay beschouwen we de positie van de faculteit Bouwkunde aan de Julianalaan binnen zijn stedenbouwkundige context.Urban StudiesTeachers of Practice /
