Losinger Marazzi implements climate strategy in its projects

Property developer and total contractor Losinger Marazzi has been positioning itself as a pioneer in sustainability in the property and construction industry for almost 20 years. In 2021, the company created the position of Chief Climate Officer. Losinger Marazzi is systematically implementing its climate strategy in its projects, including the new cantonal administration building in Emmen (LU). The project is aiming for certification with the SNBS Gold and Minergie-P-ECO sustainability labels.

What climate strategy is Losinger Marazzi pursuing?
Lennart Rogenhofer: With our climate strategy, we are pursuing the goal of reducing our CO² emissions by 30 per cent by 2030 compared to 2021. We will achieve this by focussing more on timber construction and renovation projects and by treating sustainability as a key issue in all projects. We are pursuing a scientific approach in accordance with the Science Based Targets Initiative, which also audits our target achievement, among other things.

How is the strategy being implemented in practice?
We have been fully integrating sustainability into our corporate strategy for years. Examples of this include the major projects Greencity in Zurich (Switzerland’s first 2000-watt site under development in 2012), Erlenmatt West in Basel (Switzerland’s first 2000-watt site in operation in 2013) and the sustainable Églantine neighbourhood in Morges in 2019.

Following further in-depth steps in recent years, we are systematically implementing our climate strategy. Since 2019, we have been consistently preparing a carbon footprint for the construction and operation of buildings for each project – i.e. over the entire life cycle of a project and regardless of the environmental labels we are aiming for. This has enabled us to build up a database of experience that makes it possible to estimate and reduce the emissions of future projects.

What goals is Losinger Marazzi pursuing with regard to timber construction?
Timber construction is a focal point of Losinger Marazzi’s climate strategy. This involves focussing more on building materials with low CO2 emissions, such as wood. Our climate strategy aims to minimise the life cycle emissions of a building during its construction and operation from the design stage onwards. The increased use of wood is naturally an important element here, always according to the principle of “the right material in the right place”. This means focussing on local, lightweight, bio-based materials where they are best suited in terms of their technical properties and have the greatest impact on sustainability. In addition to a reduction in CO2 emissions, this can also mean better deconstructability or a contribution to a pleasant indoor climate, for example. We are already implementing this strategy in projects such as the Greencity construction site B6 (Vergé), the administrative building of the Canton of Lucerne and the BERN 131 service building.

Current projects:
Greencity Baufeld B6 (Vergé)
In Zurich with an optimised energy concept (100 % renewable) and a materialisation fully geared towards sustainability (timber façade, lightweight interior walls, slim supporting structure, etc.)

Administrative building of the Canton of Lucerne
For around 1500 employees at Seetalplatz in Emmenbrücke (LU), including a timber atrium, SNBS Gold and Minergie-P-ECO certification

Service building BERN 131
In Wankdorf Bern with photovoltaic modules on the roof and façades, timber construction and SNBS Gold certification

Côté Parc
urban regeneration projects in Geneva and Spenglerpark in Münchenstein (BL), in which the focus was actively on utilising and upgrading the existing buildings instead of demolishing new ones
