Wind of Change: Reassembling Sustainable Building Assemblages through Rooftop Wind Energy VisionsView Abstract
03:30 PM - 05:00 PM (Europe/Amsterdam) 2022/02/17 14:30:00 UTC - 2022/02/17 16:00:00 UTC
Wind energy is increasingly seen as a means to accelerate the low-carbon energy transition in cities. This leads to the emergence of wind energy visions which describe how cities with an extensive presence of wind turbines might look like in the future. However, urban wind energy visions are not just descriptive. In order to make their visions plausible, their producers have to act intentionally and destabilize existing material, social, and institutional orderings in cities. Thus, visions are also performative, mobilizing a wide range of processes leading to the transformation of multiple urban socio- technical systems and opening up new ways of integrating wind energy in the urban environment. Drawing on vanguard visions and urban assemblages, the paper explores the role of wind energy visions in integrating wind energy in the urban built environment. This paper investigates how producers of rooftop wind energy visions interfere in and destabilize sustainable building assemblages and restabilize them into new configurations. The paper focuses on the case of the Power Nest solution. Power Nest is a roof-mounted wind and solar energy system developed by the Dutch startup Ibis Power. As such, the PowerNest solution represents a vision of turning buildings into self-contained units of energy production and consumption by installing wind turbines on rooftops. The paper explores how Ibis Power representatives act to materialize the PowerNest vision and how they intervene in the sustainable building assemblage and how their interventions affect various elements of the assemblage, including urban material forms, socio-material orderings, and socio-professional relationships.

The wastewater chain in AmsterdamView Abstract
Urban Energy 03:30 PM - 05:00 PM (Europe/Amsterdam) 2022/02/17 14:30:00 UTC - 2022/02/17 16:00:00 UTC
The wastewater chain in Amsterdam offers an opportunity to recover up to 100% of phosphorus (P) per year, versus 47% currently recovered. For water boards, like Waternet, it is difficult to scale-up centralized, decentralized, or hybrid P-recovery solutions. Because widely-used methods like Total Cost of Ownership, Mass Flow, and Life-Cycle Analysis are limited in providing a systemic assessment of risks and propagation among linked stakeholders e.g. municipalities, customers.

The Multi-Domain Mapping Model was applied to evaluate risks and opportunities propagated by four types of P-recovery technologies applied at different scales i.e. city, block, house, region; and to find an optimum scenario that fits the goals of Waternet and the city planners.

Change Propagation Indicator showed that centralized solution creates a system where Waternet is the Top-Absorber of risks/costs, and customers are Multipliers. Scenario with house-scale solution shifted risks from Waternet, indicating potential value models with other actors e.g. utilities, biotech startups, citizens, business. Scenario comparison allowed deriving system-wide patterns and change management strategies for identified actors. For each scenario we created a complementary overview of top-risks, opportunities, bottlenecks and improvements across infrastructure, as well as identified owners, and their pains & gains.

As an outcome, we developed a detailed (nexus) model of critical value chains in Amsterdam i.e. food, water, energy, etc.; and online software to analyze and link projects of other stakeholders into a single decision-support roadmap.

Analysis of energy-related investment decisions of households in Amsterdam View Abstract
Oral presentationUrban Energy 03:30 PM - 05:00 PM (Europe/Amsterdam) 2022/02/17 14:30:00 UTC - 2022/02/17 16:00:00 UTC
Household investment decisions regarding energy-efficiency measures, such as insulation, heating system renewal, or solar panel installation, have an untapped potential for reducing global energy consumption and carbon emissions. The literature has shown a growing number of studies on energy-related decision-making of households that mainly depend on their socio-economic and technical features. However, these features differ from place to place and cannot be equally important in all areas or contexts. The recent studies on the Netherlands highlight the importance of household's ownership status, education and income levels, type of the house, and spatial features among others. However, there are still no studies on the Dutch local level (i.e., city) that would demonstrate area-/context-based differences that affect energy-related household decisions. This study aims to investigate what features of households in Amsterdam affect their energy-related investment decisions. The empirical analysis will be based on the descriptive analysis and the estimation of logistic regression models using the data from the Dutch Housing Survey (WoON 2018). The results will contribute to gaining an insight for policymakers in guiding the local energy transition in Amsterdam.

What makes heating pathways sustainable? A perspective on committed emissions and water resources. View Abstract
Oral presentationUrban Energy 03:30 PM - 05:00 PM (Europe/Amsterdam) 2022/02/17 14:30:00 UTC - 2022/02/17 16:00:00 UTC
The city of Amsterdam aims to transition towards renewable heating by the year 2040 and become carbon-neutral by the year 2050. Achieving sustainable heating systems requires an optimal reduction of carbon emissions and appropriate water use. In this presentation we will therefore discuss two studies in which we analysed different renewable heating pathways towards 2050 for the city of Amsterdam in relation with climate mitigation targets and water stress. With the first study, we show that the cumulative carbon emissions between 2030 and 2050 can be reduced tenfold if ambitious early measures for the decarbonisation of electricity generation and the insulation of buildings are taken. The second study shows that the water withdrawal for heating can increase significantly due to increased use of underground thermal energy storage. The second study additionally shows that the indirect water use for heating, e.g. to produce electricity or biomass, can become larger than the direct water use for heating. Based on the results of these two studies, we argue that multi-scale perspectives, assessing multiple indicators, are needed to support a sustainable heat transition. This presentation will be relevant to anyone interested in the transition towards renewable heating systems in the city of Amsterdam and beyond. The presenters would prefer an onsite setting.
