SWEET DeCarbCH TEVT

The DeCarbCH project addresses the colossal challenge of decarbonization of heating and cooling in Switzerland within three decades and it prepares the grounds for negative CO2 emissions.

Brief information

School:

Engineering and Architecture

Status:

Completed

Period:

01.01.2024 - 31.12.2024

Overview

The overall objective of the project (with the ultimate target of net zero emissions) is to facilitate, speed up and de-risk the implementation of renewables for heating and cooling in the residential sector as well as for the service and the industry sector. Within the DeCarbCH project, the research group “Thermal Energy Systems and Process Engineering” is responsible for two work packages (WP). WP04 will adopt process integration methodology to characterize process energy demands, at company and sector level. Using these profiles, identification and assessment of integration opportunities for renewables, after implementation of economical energy efficiency measures, will be conducted. WP10 will identify and develop key methods and tools to support well-reasoned decision making for the cost-effective integration of renewables in industry. The WP will develop a multi-criteria decision making tool to assist the transition towards renewable heating and cooling.
