Machine learning models have proven to be reliable methods in classification tasks. However, little research has been conducted on the classification of dwelling characteristics based on smart meter and weather data before. Gaining insights into dwelling characteristics, which comprise of the type of heating system used, the number of inhabitants, and the number of solar panels installed, can be helpful in creating or improving the policies to create new dwellings at nearly zero-energy standard. This paper compares different supervised machine learning algorithms, namely Logistic Regression, Support Vector Machine, K-Nearest Neighbor, and Long-short term memory, and methods used to correctly implement these algorithms. These methods include data pre-processing, model validation, and evaluation. Smart meter data, which was used to train several machine learning algorithms, was provided by Groene Mient. The models that were generated by the algorithms were compared on their performance. The results showed that the Long-short term memory performed the best with 96% accuracy. Cross Validation was used to validate the models, where 80% of the data was used for training purposes and 20% was used for testing purposes. Evaluation metrics were used to produce classification reports, which indicates that the Long-short term memory outperforms the compared models on the evaluation metrics for this specific problem.

Met belangstelling bestudeert Martien Visser het 600 pagina’s tellende advies van het ‘Committee on Climate Change’ dat komt met aanbevelingen voor de aanpak van de Britse energietransitie tot 2050. Het rapport verdient volgens hem onze aandacht omdat Nederland er veel van kan opsteken.

The Utrecht SBE16 Conference. From the introduction: "The conference is part of the Sustainable Built conference series and is as such considered to be part of the pre-eminent international conference series on sustainable building and construction endorsed by iiSBE, UNEP-SBO and FIDIC. The Utrecht SBE16 conference is hosted by the Centre of Expertise Smart Sustainable Cities of HU University of Applied Sciences Utrecht, in partnership with six Dutch Universities of Applied Sciences (Avans, Saxion, Rotterdam, The Hague, Zuyd, InHolland) and the Utrecht Sustainability Institute (USI). The Transition Zero conference provides us with a unique opportunity to meet transition professionals in urban sustainability from all over Europe and beyond and to learn about the latest developments and best (inter)national practices in urban sustainability. The rich interest in the conference, made it possible to offer research as well as practitioner-driven tracks on topics related to the conference title. The conference brought together excellent future-minded practitioners, researchers and thought leaders from the R&I community, specialists and professionals on zero energy homes and transition of the built environment."

Samenvatting: Nu gemeenten grote ambities hebben voor zero emissie stadslogistiek en dat ook omzetten in harde beleidsmaatregelen voor 2025 wordt de urgentie om in actie te komen voor logistieke bedrijven steeds groter. Servicelogistiek is als deel van stadslogistiek onderbelicht en veelvuldig over het hoofd gezien, zowel in onderzoek als in beleid. In 2017 is de Hogeschool van Amsterdam, mede gefinancierd door SIA, in samenwerking met UNETOVNI en de gemeente Amsterdam een exploratief onderzoek gestart naar servicelogistiek in de stad. In dit artikel de bevindingen van dat onderzoek en een vooruitblik hoe verschillende kluscategoriën en nieuwe technologieën gaan bijdragen aan servicelogistiek met cargobikes en elektrische bestelbussen.

In dit magazine lees je over de uitdagingen van interdisciplinair onderzoek en welke mogelijkheden er zijn om de samenwerking tussen disciplines te versterken. We geven tips voor het verbeteren van een onderzoeksopzet, vertellen over instrumenten die het samenwerkingsproces tussen verschillende disciplines verbeteren, en bediscussiëren welke methoden leiden tot interdisciplinaire onderzoeksresultaten.

Booklet met bevinden van het project 'Samen zichtbaar duurzaam' dat zich richt op de vraag: “hoe maken we zichtbaar dat duurzame verandering mogelijk en wenselijk is?”Binnen en buiten de HvA zijn er hoge ambities om met verschillende benaderingen en praktijkgericht onderzoek duurzame verandering teweeg te brengen. Mede dankzij de betrokken lectoraten, Centres of Expertise en de Green Office worden er steeds meer zaadjes geplant en verbindingen gelegd rondom het thema Duurzaamheid. Toch gebeurt het nog veel dat men niet van elkaar af weet en worden best en worst practices niet met elkaar gedeeld. Dit project wil daar zichtbare verandering in brengen. Vanuit verschillende technische, digitale en creatieve kanten, en met studenten, docenten, onderzoekers en de praktijk wordt het thema duurzame verandering op zichtbare, creatieve, interactieve enspeelse wijze benaderd.Dit project is onderdeel van de Cross-overregeling. Deze zogenaamde cross-overregeling is een initiatief van het Centre of Expertise for Creative Innovation (CoECI)en het Centre of Expertise City Net Zero (voorheen UT). De projecten die een financiële bijdrage hebben gekregen gaan over complexe uitdagingen uit de Metropoolregio Amsterdam, die vragen om een integrale benadering, met input vanuit verschillende disciplines. De regeling beoogt nieuwe samenwerkingen tussen verschillende disciplines en tussen onderwijs en onderzoek aan te jagen.

Dealing with and maintaining high-quality standards in the design and construction phases is challenging, especially for on-site construction. Issues like improper implementation of building components and poor communication can widen the gap between design specifications and actual conditions. To prevent this, particularly for energy-efficient buildings, it is vital to develop resilient, sustainable strategies. These should optimize resource use, minimize environmental impact, and enhance livability, contributing to carbon neutrality by 2050 and climate change mitigation. Traditional post-occupancy evaluations, which identify defects after construction, are impractical for addressing energy performance gaps. A new, real-time inspection approach is necessary throughout the construction process. This paper suggests an innovative guideline for prefabricated buildings, emphasizing digital ‘self-instruction’ and ‘self-inspection’. These procedures ensure activities impacting quality adhere to specific instructions, drawings, and 3D models, incorporating the relevant acceptance criteria to verify completion. This methodology, promoting alignment with planned energy-efficient features, is supported by BIM-based software and Augmented Reality (AR) tools, embodying Industry 4.0 principles. BIM (Building Information Modeling) and AR bridge the gap between virtual design and actual construction, improving stakeholder communication and enabling real-time monitoring and adjustments. This integration fosters accuracy and efficiency, which are key for energy-efficient and nearly zero-energy buildings, marking a shift towards a more precise, collaborative, and environmentally sensible construction industry.

One of the most complex and urgent challenges in the energy transition is the large‐scale refurbishment of the existing housing stock in the built environment. In order to comply with the goals of the Paris convention, the aim is to live “energy‐neutral,’’ that is, a dwelling should produce as much sustainable energy as it consumes on a yearly basis. This means that millions of existing houses need to undergo a radical energy retrofit. In the next 30 years, all dwellings should be upgraded to nearly zero‐energy buildings, which is a challenge to accomplish for a reasonable price. Across the EU, many projects have developed successful approaches to the improvement of building technologies and processes, as well a better involvement of citizens. It is important to compare and contrast such approaches and disseminate lessons learned.In practice, it is crucial to raise the level of participation of inhabitants in neighborhood renovation activities. Therefore,the central question of this issue is: How can we increase the involvement of tenants and homeowners into this radicalenergy renovation?
