While the optimal mean annual temperature for people and nations is said to be between 13 °C and 18 °C, many people live productive lives in regions or countries that commonly exceed this temperature range. One such country is Australia. We carried out an Australia-wide online survey using a structured questionnaire to investigate what temperature people in Australia prefer, both in terms of the local climate and within their homes. More than half of the 1665 respondents (58%) lived in their preferred climatic zone with 60% of respondents preferring a warm climate. Those living in Australia's cool climate zones least preferred that climate. A large majority (83%) were able to reach a comfortable temperature at home with 85% using air-conditioning for cooling. The preferred temperature setting for the air-conditioning devices was 21.7 °C (SD: 2.6 °C). Higher temperature set-points were associated with age, heat tolerance and location. The frequency of air-conditioning use did not depend on the location but rather on a range of other socio-economic factors including having children in the household, the building type, heat stress and heat tolerance. We discuss the role of heat acclimatisation and impacts of increasing air-conditioning use on energy consumption.

Participatory energy planning at the local level engages citizens, builds legitimacy and trust, and increases successful implementation of renewable energies. In the context of heat planning, technology choices highly vary depending on the local context and social conditions and including social input therefore benefits the planning process. This research adds to the current literature, which lacks concrete examples and verified approaches that clarify what the guiding principles of participatory energy planning are and how the opportunities and challenges can be dealt with. This paper elaborates on these opportunities and challenges and proposes a process design, using multiple tools (a survey, an Information-choice Questionnaire, and workshops) to collect the social input that is necessary to make technology choices in a participatory manner. The process design is applied and tested in a case study of a Dutch neighbourhood and lessons learned are drafted as a basis for further research.

ALE organised an event with Parktheater Eindhoven and LSA-citizens (the Dutch umbrella organisation for active citizens). Five ALE students from the minor Imagineering and business/social innovation took responsibility for concept and actual organisation. On Jan 18th, they were supported by six other group members of the minor as volunteers. An IMEM-team of 5 students gathered materials for a video that can support the follow-up actions of the organisers. The students planned to deliver their final product on February 9th. The theatre will critically assess the result and compare it to the products often realised by students from different schools or even professional ones, like Veldkamp productions. Time will tell whether future opportunities will come up for IMEM. The collaboration of ALE and IMEM students is possible and adding value to the project.More than 180 visitors showed interest in the efforts of 30 national and local citizen initiatives presenting themselves on the market square in the theatre and the diverse speakers during the plenary session. The students created a great atmosphere using the qualities of the physical space and the hospitality of the theatre. Chair of the day, Roland Kleve, kicked off and invited a diverse group of people to the stage: Giel Pastoor, director of the theatre, used the opportunity to share his thoughts on the shifting role of theatre in our dynamic society. Petra Ligtenberg, senior project manager SDG NL https://www.sdgnederland.nl/sdgs/ gave insights to the objectives and progress of the Netherlands. Elly Rijnierse, city maker and entrepreneur from Den Haag, presented her intriguing efforts in her own neighbourhood in the city to create at once both practical and social impacts on SDG 11 (sustainable city; subgoal 3.2). Then the alderman Marcel Oosterveer informed the visitors about Eindhoven’s efforts on SDGs. The plenary ended with very personal interviews of representatives of two impressive citizen initiatives (Parkinson to beat; Stichting Ik Wil). In the two workshop rounds, ALE took responsibility for two workshops. Firstly the workshop: Beyond SDG cherrypicking: using the Economy for the common good’, in cooperation with citizen initiative Ware winst Brabant en Parktheater (including Social innovation-intern Jasper Box), secondly a panel dialogue on local partnerships (SDG 17) for the sustainable city (SDG 11) addressing inclusion (SDG 10) and the livability (SDG 3) with 11 representatives from local/provincial government, companies, third sector and, of course: citizen initiatives.
Recent research by the renowned Royal Institution of Chartered Surveyors (RICS) shows that more than 2/3 of all CO2 is emitted during the building process and less than 1/3 during use to heat the building and the tap water. Lightweight, local and biobased materials such as biocomposites to replace concrete and fossil based cladding are in the framework of climate change, a necessity for future building. Using plant fiber in polymer composites is especially interesting for construction since natural fibers exhibit comparative good mechanical properties with small specific weight, which defines the potential for lightweight constructions. The use of renewable resources, will affect the ecosystem favorably and the production costs of construction materials could also decrease. However, one disadvantage of natural fibers in plastics is their hydrophilic properties. In construction the materials need to meet special requirements like the resistance against fluctuating weather conditions (Ticoalu et al., 2010). In contrast to synthetic fibers, the natural ones are more moisture- and UV-radiation-sensitive. That may lead to degradation of these materials and a decreasing in quality of products. (Lopez et al., 2006; Mokhothu und John, 2017) Tanatex and NPSP have approached CoE BBE/Avans to assist in a study where fibres impregnated with the (modified) Tanatex products will be used for reinforcement of thermoset biopolymers. The influence of the different Tanatex products on the moisture absorption of natural/cellulosic fibers and the adhesion on the fibers on main composite matrix will be measured. The effect of Tantex products can optimize the bonding reaction between the resin and the fibers in the (bio) composite and result to improved strength and physico-chemical properties of the biocomposite materials.

In summer 2020, part of a quay wall in Amsterdam collapsed, and in 2010, construction for a parking lot in Amsterdam was hindered by old sewage lines. New sustainable electric systems are being built on top of the foundations of old windmills, in places where industry thrived in the 19th century. All these examples have one point in common: They involve largely unknown and invisible historic underground structures in a densely built historic city. We argue that truly circular building practices in old cities require smart interfaces that allow the circular use of data from the past when planning the future. The continuous use and reuse of the same plots of land stands in stark contrast with the discontinuity and dispersed nature of project-oriented information. Construction and data technology improves, but information about the past is incomplete. We have to break through the lack of historic continuity of data to make building practices truly circular. Future-oriented construction in Amsterdam requires historic knowledge and continuous documentation of interventions and findings over time. A web portal will bring together a range of diverse public and private, professional and citizen stakeholders, each with their own interests and needs. Two creative industry stakeholders, Yume interactive (Yume) and publisher NAI010, come together to work with a major engineering office (Witteveen+Bos), the AMS Institute, the office of Engineering of the Municipality of Amsterdam, UNESCO NL and two faculties of Delft University of Technology (Architecture and Computer Science) to inventorize historic datasets on the Amsterdam underground. The team will connect all the relevant stakeholders to develop a pilot methodology and a web portal connecting historic data sets for use in contemporary and future design. A book publication will document the process and outcomes, highlighting the need for circular practices that tie past, present and future.
