Title: 'the energy transition through the eyes of a developer'

by Maarten Kokshoorn - Heijmans BV

The energy transition is a very dynamic process, in which the energy issues that up to now were obvious are suddenly no longer there. People are asked for other (new) products, for other collaborations and for new role allocations. A lot is changing and a lot is going to change. Heijmans is a company that focuses on achieving a sustainable and healthy living environment. We take care of area development, the construction of homes and utility buildings and the construction of infrastructure and the long-term management of these components. In this lecture I will discuss the developments of the energy transition from the perspective of Heijmans to the future. I also zoom in on a number of practical examples from current projects and the energy transition to provide insight into what we encounter when creating an energy-neutral neighbourhood.

Biography Maarten Kokshoorn (40)

Title: "It’s not easy being green"

by Gerdien de Vries - assistant professor Public Management and Organisation at Delft University of Technology; faculty of Technology, Policy and Management

17 September 2019
In order to reach climate goals in the long run, people have to act sustainably in the short run. Unfortunately, however, environmental policy goals are hardly reached. People find it not easy being green. This presentation introduces psychological barriers (such as cognitive biases, emotions, expectations, and perceived hassle) as important reasons for this shortfall. It will explain the barriers with examples, reveal why they occur, and identify who are most vulnerable. Finally, recommendations on possible ways to overcome these pitfalls will be provided for policymakers and other practitioners.

Title: "Business opportunities and policy challenges for the adoption of energy flexible buildings"

by Erwin Mlecnik - Management in the Built Environment, Faculty of Architecture and the Built Environment, Delft University of Technology, The Netherlands

18 June 2019
The introduction of smart electricity and heating networks requires buildings to become ‘smart grid ready’. In this framework it is expected that future buildings will be able to manage their demand and generation according to, not only local climate conditions and user needs, but also related to signals in case of limited availability or abundance of energy on the connected distribution network. While case studies prove that this is technically feasible, the adoption of such energy flexibility in buildings depends largely on social and commercial acceptance. The development of energy flexible buildings will introduce new challenges for various stakeholders, which have been researched in the framework of the IEA EBC Annex 67 Energy Flexible Buildings. This lecture identifies key opportunities and barriers experienced by stakeholders in various countries. The research results illustrate the need to develop related business models and supporting energy policy.

Title: City neighbourhood decarbonisation from theory to practice

By Riccardo M. Pulselli; Project manager @ Indaco2

10 April 2019
Sustainability takes its roots in “non equilibrium” thermodynamics and evolutionary physics. Particularly the concept of dissipative structures by Ilya Prigogine applies to cities and allows for raising awareness on the climate crisis.

Strategies for climate change mitigation in cities start from knowledge of real “dissipative” processes to identify challenges and opportunities. Carbon accounting is among monitoring tools to inform administrators, citizens and other stakeholders and address choices for climate action. In particular, a Carbon Accounting framework have been developed within the City-Zen project and demonstrated through roadshows in different European cities. The assessment of greenhouse gas emissions allowed to inform urban policies and design through clear communication and to estimate the effects, in terms of Carbon Footprint mitigation, of integrated measures for carbon neutrality.

Riccardo M. Pulselli, architect, PhD in environmental sciences, is founder and president of Indaco2 - Indicators, Assessments and CO2, a company focussed on environmental accounting applied to manufacturing and agricultural processes, buildings and building technologies, neighbourhoods and cities. He is author of City Out of Chaos. Urban Self-organization and Sustainability (WITpress 2009 – coauthored with Enzo Tiezzi), The Moving City (Laris 2011), The Rampant Garden (Edifir 2014 – coauthored with G Paolinelli and S Bastianoni). He has been visiting researcher at MIT (Boston, US), WUR (Wageningen, NL) and TU Delft (Delft, NL). He has conducted research, in collaboration with TU Delft, for assessing the effects, in terms of carbon footprint mitigation, of energy transition plans in European cities.

Title: ''Cost effective Heat-Transition'

By Folckert van der Molen; researcher Climate Air and Energy; PBL Planbureau voor de Leefomgeving

19 maart 2019
Folckert van der Molen is an energy and sustainability researcher at the PBL Netherlands Environmental Assessment Agency. He started his career there after his studies in Liberal Arts and Sciences at Utrecht University, focusing on Economic Geography. Research areas include sustainable heating in the built environment and regional energy transition processes. Currently working towards facilitating the implementation of the goals for heating in the built environment from the national Climate Agreement on a municipality level in the Netherlands.

This presentation provides an overview of regional challenges in planning the heat-transition of the built environment and proposes methods for solving these challenges. Lessons are drawn from a recent regional case-study conducted in the Drechtsteden region. This study shows how national policy van be translated to a region and municipality level through an analysis of technical and economic solutions for reducing the demand for natural gas. In this case study the researchers participated in a regional decision-making process. Some meta-conclusions can be drawn about effective stakeholder participation and implications for national policy.

Title: ’Cool heat grids’  for sustainable urban energy systems

By Sabine Jansen; Assistant Professor faculty of Architecture and the built environment

15 January 2019
This lunch lecture presents ongoing projects on (ultra) low temperature heat grids for sustainable urban or neighbourhood energy systems, as one of the sustainable alternatives for heating with natural gas.

In the built environment, many heat sources are available at temperatures between 15 and 30 degrees, such as for example waste water, surface water, cooling from supermarkets or datacentres, and solar thermal energy. Also, the heating and cooling demand of buildings exist in this temperature range, or can make use of these low temperature sources by upgrading the heat with a heat pump.  In this lecture two projects on this topic are presented. The ‘KoWaNet’ project ( aims at developing smart thermal heat grids that intelligently connect all these sources and demands. These smart and open ‘cool heat grids’ will optimally connect all users – producers, consumers and those that do both – in order to efficiently deliver sustainable, economic and secure heat or cold to its customers. The second – recently granted - project is on low temperature feed-in solar heat grids. This energy concept will be briefly explained and the influence of the insulation level of the connected buildings will be discussed.

Sabine Jansen works as assistant professor at the faculty of Architecture at Delft University of Technology since 2014. She is involved in education on sustainable energy systems as well as various research projects related to the energy transition for the built environment. She graduated from the same faculty in 2002.  After several years of experience at various engineering consultancies, she received her PhD degree in 2013 on the application of the exergy concept to energy systems in the built environment.

At the moment she focuses on two research topics:  bringing innovative and future-proof energy solutions into practice, and integrating circularity into the challenge of the energy transition, which is actually a 'resource transition'.
