Heat supply concept 2040 for the city of Zurich

In 2022, the electorate of the city of Zurich approved the net zero 2040 climate protection targets. These targets aim to reduce the city's direct emissions to net zero by 2040 and indirect emissions to 30% below 1990 levels. This also affects the city's heat supply. As a result, the previous Energy Supply Concept 2050 will be replaced by the Heat Supply Concept 2040.

TEP Energy is supporting the city of Zurich in further developing the heat supply concept, which serves as the basis for the city's municipal energy planning. Against the backdrop of the energy and climate policy objectives of Switzerland, the Canton of Zurich and, above all, the city of Zurich, the concept shows how the city can manage without fossil fuels by 2040. The calculations are carried out using the building stock model (GPM) in close cooperation with the city of Zurich. The starting point is the current building stock and the structural reserves per plot. The GPM is then used to simulate energy efficiency measures and energy source changes. The energy planning constraints and the Energy Act of the Canton of Zurich play just as important a role here as the age and service life of the heating systems.

The results, which are differentiated in terms of time and space, enable the city of Zurich to set priorities and define implementation measures. The results also serve to provide accurate information to the population, property owners and businesses. This is done in the city of Zurich's EnerGIS.

Reference projects

Swiss Energy Perspectives

Under the leadership of Prognos, TEP Energy will work with other renowned partners to develop the Swiss Energy Perspectives on behalf of the Swiss Federal Office of Energy. 

Scope 3 emissions of a portfolio of existing commercial buildings and new construction projects

Together with its partner Sustainserv, TEP Energy is supporting one of Switzerland's leading property managers and developers with environmental reporting (ESG). To this end, methodological issues are being clarified and initial results published in the environmental report. This includes the calculation of the greenhouse gas emissions of Scope 3 of the 'Construction' phase (construction + disposal) of maintenance and renovation activities for the entire building portfolio which includes existing buildings but also newly built projects.

Net-zero greenhouse gas emissions in the building sector

Together with partners, TEP Energy is developing methodological principles (F0) based on the WLCNN method, examining the achievability of net-zero targets (F1) using technical and economic scenarios and developing implementation strategies (F2, F3) with technical and political concepts. In addition, existing standards are analysed in order to harmonize regulations and ensure comparability (F4).

Potential and feasibility study for heat supply in Aesch

The municipality of Aesch (BL) is developing a climate-friendly, economical and secure heat supply for households and businesses. The aim of the municipality is to achieve the national climate targets (net zero by 2050) and build a sustainable energy infrastructure. As part of the feasibility study, renewable energy sources for heating and hot water, including geothermal energy, local and district heating solutions and air-to-water heat pumps, were analysed. TEP Energy analysed their economic viability and possible implementation in various sub-areas. The study was carried out in collaboration with eicher+pauli, the municipality of Aesch and the Basel-Landschaft Office for Environmental Protection and Energy and forms the basis for the municipality's heat planning.

Energy renovation rates in the building sector

Various federal and cantonal energy and climate policy measures are aimed at significantly increasing the energy renovation rate. Based on this comprehensive survey, the report shows how the energy renovation rate has developed in recent years and how high it currently is.

Municipal heat planning in Volketswil

With reference to its climate policy objectives and as a result of its energy city process, the municipality of Volketswil is having its municipal energy planning revised.

Municipal energy planning in Glarus

Based on the cantonal energy law revision of 2021, the municipality of Glarus is revising its municipal energy planning with the aim of achieving a fossil-free heat supply. TEP Energy is supporting the municipality with its solutions, such as the Spatial Energy Analysis Toolbox (SEAT) and the building stock model, in order to achieve the energy and climate targets in a sustainable and economically efficient manner.

SURE - SUstainable and REsilient energy for Switzerland

Sweet - SURE analyses the impact of disruptive events on the Swiss energy system. TEP Energy is working on energy demand topics such as the development of demand for energy sources in Switzerland, the impact of shocks on the demand load and the potential use of large heat pumps.

MEDIUS

MEDIUS bridges the gap between green finance and green projects to decarbonize buildings at scale.

Country-specific Market Reports for Buildings

Building Market Briefs (BMB) is a Climate KIC initiative within the flagship Building Technologies Accelerator (BTA) that aims to gather and promote knowledge about the buildings' and construction sector to promote low carbon investment and scaling.

Heating Initiative Switzerland

On behalf of the Swiss Heating Initiative (WIS), the decarbonization of the heating sector will be examined by 2050. Spatial potential analyzes and the Swiss building stock model (GPM) are used.

CoolCity

Assessment of the potential for lake water use for heating and cooling in the city of Zurich

Energy-Saving Contracting

Increasing energy efficiency is one of the central pillars of Swiss energy policy and energy-saving contracting contributes to this goal.
