Ending subsidies for fossil fuel heating systems from 2025, and phasing out gas boilers and other fossil fuel heaters by 2040. These are just two of the outcomes of a political agreement between the EU Council and the European Parliament, which was reached on December 7, 2023. Which measures were agreed …

The built environment requires energy-flexible buildings to reduce energy peak loads and to maximize the use of (decentralized) renewable energy sources. The challenge is to arrive at smart control strategies that respond to the increasing variations in both the energy demand as well as the variable …

In Europe, green hydrogen and biogas/green gas are considered important renewable energy carriers, besides renewable electricity and heat. Still, incentives proceed slowly, and the feasibility of local green gas is questioned. A supply chain of decentralised green hydrogen production from locally generated …

Community energy can be conceptualized as a social movement, which aims to develop a sustainable, democratic, and localist energy system. Community energy organizations often take the form of cooperatives and strive for a high level of participation at the neighborhood level. Recently, community energy …

Community energy can be conceptualized as a social movement, which aims to develop a sustainable, democratic, and localist energy system. Increasingly, community energy initiatives aim to develop citizen-led heating projects. District heating projects are characterized by costly investments, a substantial …

When we think of the energy transition, we think of new technology that will enable us to get rid of fossil fuels. However, we are extremely energy addicted worldwide. Now, with the energy crisis, we seem to be able to turn down our heating and put on a warm sweater from one day to the next. This is …

This research presents a case study exploring the potential for demand side flexibility at a cluster of university buildings. The study investigates the potential of a collection of various electrical devices, excluding heating and cooling systems. With increasing penetration of renewable electricity …

Decentralised renewable energy production in the form of fuels or electricity can have large scale deployment in future energy systems, but the feasibility needs to be assessed. The novelty of this paper is in the design and implementation of a mixed integer linear programming optimisation model to minimise …

This Powerpoint is part of the project Twomes. This deliverable contains a presentation about the heat balance model and inverse-grey-box analysis tools that support automated estimation of crucial parameters of buildings, installations and comfort needs in individual homes and utility buildings based …

There is an urgent need for energy renovation of the existing building stock, in order to reach the climate goals, set in Paris in 2016. To reach climate targets, it is important to considerably lower energy demand as well as switch to fossil-free heating systems. Unfortunately, renovation rates across …
