Toolbox Session: Open-source web-tool for district energy planning
Mannheim2020 - European Sustainable Cities & Towns Conference Series
Online Session – 2 October 2020 – 9:30-11:00

The THERMOS Toolbox Session at the Mannheim2020 Conference – the 9th Edition of the European Sustainable Cities & Towns Conference Series- will introduce the THERMOS software as a viable means for cities, utilities and consultants to master-plan economically feasible low-carbon thermal energy systems in Europe more cost and time effectively than is currently possible. Participants will discuss with different THERMOS users about their experience and results from applying the software for planning and advancing low-carbon district energy network projects and conducting their pre-feasibility studies.

The session will include a virtual introduction and test walk through the tool to get participants started in taking first steps with the software to accelerate their own planning of sustainable heating and cooling networks.

Mannheim2020 will also see the official announcement of THERMOS Training Pathway D. A free training courses to advance district energy planning knowledge and enable expert users to apply the THERMOS software for their context and work.

HotMaps Final Conference: Heating and Cooling planning for greener cities
Online Event

On 30 June, THERMOS will take part in the final conference of our partner project HotMaps to lay down the complementary use of the tools developed by both projects to support local energy planners.

THERMOS partner CREARA will present the THERMOS tool together with e-Think, partner to the HotMaps project in a parallel session on “Energy planning with Hotmaps & Thermos” from 11:15-12:00 CEST.

The conference marks the final conference of the HopMaps project and aims to discuss the Hotmaps toolbox as the outcome of the project, as well as other available technologies and models to decarbonise heating and cooling locally.

Like THERMOS, the HotMaps toolbox was developed together with cities to be as close to the needs of local planners possible in developing their low-carbon strategies. HotMaps is designed to assist planners in estimating the heating and cooling demand, as well as the potential of local renewable energy in the area to cover this demand. Building on HotMaps results on sources, planners can refer to the THERMOS tool for identifying and optimising possible district network solutions connecting the sources with the demand.

THERMOS - HOTMAPS - PLANHEAT Joint Heating & Cooling Planning Webinar
May, 14 2019

On 14 May 2019 THERMOS and its H2020 partner projects HOTMAPS and PLANHEAT are organising a joint webinar on state-of-the-art heating and cooling planning introducing the innovative energy planning tools developed by all three projects.

The webinar will focus on enabling cities to decarbonise emissions from heating and cooling by providing them knowledge and information needed to develop sustainable heating and cooling strategies at local level (heat demand density, renewable energy potentials, load profiles, excess heat sources…). This webinar - organised in the framework of CELSIUS Talks series and part of the EUSEW 2019 Energy Days - will present three tools, developed in close collaboration with local authorities all over Europe to  support energy/city planners in this process while making it much faster and more efficient.

Discussions will focus on key questions energy planners will be able to answer easily and quickly thanks to these tools:

  • What is the heating and cooling demand in the specific area?
  • Are the surrounding renewable and waste heat resources enough to cover the demand?
  • What are the costs of different technological solutions?
  • What would be the optimal district heating and cooling network to satisfy my planning criteria?

Interactive workshop on heat planning and mapping in Europe
13:00 - 16:00 November 12, 2018
Aalborg University, Aalborg

Take part in the "Interactive workshop on heat planning and mapping in Europe" co-organised by THERMOS along with its sister projects HotmapsPlanheat  and Heat Roadmap Europe as a side event to the conference on 12 November 2018.

The energy transition is already well underway. However, it is happening at different speeds across Europe. In order to fulfil the EU’s climate and energy goals, the heating and cooling sector must sharply reduce its energy consumption and cut its use of fossil fuels.

This session will emphasise the importance of research, innovation and demonstration projects for thermal planning tools, while at the same time providing a menu of possible pathways and instruments that can inform the Heating and Cooling debate and relevant legislative initiatives, optimise mainstream and replicate state-of-the-art practice, aimed at making the resilient Energy Union a reality.

H2020 programme projects Hotmaps, PLANHEAT, THERMOS and Heat Roadmap Europe offer innovative approaches for the integration of sustainable heating and cooling infrastructure at European, national, regional and local levels, thereby assisting EU Member States in the practical aspects of the implementation of Article 14 of the Energy Efficiency Directive on efficiency in heating and cooling.

Join fellow academics and researchers, industry and public sector representatives at a pre-event of the 4th Generation District Heating Conference to assess four ground-breaking tools for energy planning. In its own way, each project works to optimise thermal mapping / modelling tools to enable faster upgrade, refurbishment and expansion of existing systems, as well as tap into renewable sources and the potential of waste/excess heat.

Fostering renewable heat in the UNECE region
9:30 - 18:00 November 13, 2017
Federal Ministry for the Environment, Robert-Schuman-Platz 3, Bonn

A workshops, held alongside of the COP23 climate conference in Bonn, seeks to establish a venue for the exchange of information on Renewable Energy within the region. Collaboratively, decision makers from governments, market regulators and businesses being active in selected UNECE countries shall identify both challenges and barriers to the deployment of renewable heat sources and possible solutions for addressing these.

Most notably, the one-day event feature two modules that are meant to create room for exchange: In a first step, participants will have the opportunity to present, discuss and critically assess the current market situation for renewable heat in their countries. Moreover, a multi-peer discussion process shall enable the representatives to address difficulties, share experience and outline adequate solutions with regards to the development of renewable heat markets.

The event is organized by the German Energy Agency (dena) in close cooperation with the UNECE Group of Experts on Renewable Energy (GERE) and funded by the German Federal Ministry for Economic Affairs and Energy.

Please register until 6 November 2017 via dena‘s website.
