The Global Urban Lectures are 15-minute lectures on themes related to sustainable urbanisation, delivered by renowned experts, UN-Habitat partners and UN-Habitat staff. The lectures have been ranked among the best MOOCs (Massive Open Online Courses) on cities.

PV systems are used more and more. Not always is it possible to install them in the optimal direction for maximum energy output over the year. At the Johan Cruijff ArenA the PV panels are placed all around the roof in all possible directions. Panels oriented to the north will have a lower energy gain than those oriented to the south. The 42 panel groups are connected to 8 electricity meters. Of these 8 energy meters monthly kWh produced are available. The first assignment is to calculate the energy gains of the 42 panel groups, and connect these in the correct way with the 8 energy meter readings, so simulated data is in accordance with measured data.Of the year 2017 there are also main electricity meter readings available for every quarter of an hour. A problem with these readings is that only absolute values are given. When electricity is taken of the grid this is a positive reading, but when there is a surplus of solar energy and electricity is delivered to the grid, this is also a positive reading. To see the effect on the electricity demand of future energy measures, and to use the Seev4-City detailed CO2 savings calculation with the electricity mix of the grid, it is necessary to know the real electricity demand of the building.The second assignment is to use the calculations of the first assignment to separate the 15 minute electricity meter readings in that for real building demand and for PV production.This document first gives information for teachers (learning goals, possible activities, time needed, further reading), followed by the assignment for students.

The use of events as policy tools in cities has become widely recognized. However, most studies concerning this topic do not capture the complex interrelationships that underpin the development of an eventful city. This study applies a practice approach, in order to analyze the dynamics of the eventful city practice. It places the urban event practice centrally in the analysis and focuses on the actual "sayings and doings" of the practice. The event practice of the 2015 Incubate festival in Tilburg, the Netherlands, is analyzed by means of ethnographic methods, including participant observation and interviews. Incubate illustrates how both the city and the event are performed within the practice: the event shapes the city and the city shapes the event. However, the integration of the festival into alternative spaces in the city means that it does not increase the visibility of Tilburg, and therefore fails to deliver value to its eventful city policy.

This study describes the process of developing a typical dish for a slow city, using the lens of co-creation and coproduction. The slow movement argues that appreciation of local cuisine increases through events and developing slow food practices. Participant observation and interviews with actors involved in the development process revealed the symbolic components used to enhance the cultural heritage of Vizela, Portugal as a slow city. The research shows that the slow city initiative has gradually provided the basis for a gastronomic attraction to support tourist development. The development of a typical dish for the city was found to aid the recovery and revalorization of local knowledge, while the support of gastronomic culture by the local authority and community participation helped to strengthen regional identity and to develop an attractive and sustainable tourist offer. Thus, this study revealed the importance of residents in this development process as well as showed requirements that may support the rescue and cocreation of typical dishes for tourism.

In discussions on smart grids, it is often stated that residential end-users will play a more active role in the management of the electric power system. Experience in practice on how to empower end-users for such a role is however limited. This paper presents a field study in the first phase of the PowerMatching City project in which twenty-two households were equipped with demand-response-enabled heating systems and white goods. Although end-users were satisfied with the degree of living comfort afforded by the smart energy system, the user interface did not provide sufficient control and energy feedback to support an active contribution to the balancing of supply and demand. The full potential of demand response was thus not realized. The second phase of the project builds on these findings by design, implementation and evaluation of an improved user interface in combination with two demand response propositions. © 2013 IEEE.
