seele takes responsibility – our goal: net zero

In the transformation to carbon neutrality, the construction sector is a key industry. As an industrial company, we have a special responsibility because we use raw materials to build unique façades. Our goal is to use scarce resources as efficiently as possible. To this end, we obtain energy from renewable sources, manage raw materials responsibly and take steps to ensure the longevity of our products.

As an owner-managed company, we can make quick decisions and take swift action. We don’t simply talk about sustainability, we shape it. We are working intensively to reduce our carbon footprint. Similarly, we assume responsibility for supporting our customers in achieving their sustainability goals. We are moving intently along the route to net zero. By when? Better today than tomorrow.

Our areas of action:

  • Renewable energy
  • Reducing and recycling waste
  • Reporting and transparency
  • Raising awareness
  • Recommendations and life cycle assessment

seele's fact check on sustainability

nav-left-arrow nav-right-arrow
seele's route to net zero: We are doing everything possible to be climate neutral sooner rather than later. Our sustainability strategy is manifested for us and our customers and implemented into many processes.
With our CO2 calculation tool we are able to evaluate different design solutions and identify optimisation potential. Our tool is constantly undergoing further development and harmonised with manufacturers’ latest EPDs (environmental product declarations).
The photovoltaic systems at our various sites have a capacity of 375 kWp. Another 190 kWp are in the planning stage. In total, this will save 200 metric tons of CO2.
Retrofitting all the lighting in the workshops and offices at seele GmbH to use LED light sources and installing a demand-based lighting control system now results in an annual energy saving of 200,000 kWh.
Our recycling rate in 2022 was 91%. Since 2017, the volume of waste has been reduced by 43%. And in the same period, the amount of hazardous waste was reduced by 78%.
Digital processes, meeting rooms with modern touchscreens and the conversion of printers to chip-based sensor technology led to a reduction in paper consumption of around 50%.
We provide maintenance at regular intervals for around 70 projects, thus extending the service life of our construction projects.
BREEAM, LEED or DGNB – we assist our customers with certification and we are already creating comprehensive material reports for our projects.
We raise awareness among our employees with our Environment Week, the annual waste report and periodic training. We also sponsor training as energy and resource scouts and actively participate on expert panels within the industry.
seele GmbH, se-austria GmbH & Ko. KG, and seele pilsen s.r.o. are certified according to DIN EN ISO 14001 (environmental management systems). seele GmbH is also certified according to DIN EN ISO 50001 (energy management systems). Issues concerning environmental management are an integral part of our supplier audits.

Renewable energy – with high investments

There is no question that the transition to climate neutrality needs clever concepts and lots of money. As an owner-managed company, we have the advantage of being able to make decisions quickly and to apply the necessary financial resources. In the past, we focused primarily on saving energy. Now we are focusing on generating it. We produce our own electricity and save 136 metric tons of CO2. We are also working on concepts for heat recovery. And we supplement whatever electricity we cannot produce ourselves by purchasing it from renewable energy sources. We establish precedents that are measurable. Our goal: shift to 100% renewable energy.

Reducing and recycling waste – prevention make economic sense

When it comes to waste, too, the goal is prevention and to return valuable raw materials to the circular economy. With the steady reduction of waste and a recycling rate of over 90%, we are on the right track. We scrutinise every process and optimise what is possible: we avoid surplus deliveries, utilise modern tracking methods and nesting software, convert packaging materials, replace hazardous materials, and save paper by using digital processes. Our goal: To improve measurably every year (waste report).

Reporting and transparency – basics for agile sustainability management

Our modern building management system records consumption so we can act in line with performance indicators. Monitoring of the production machinery is also very important in order to optimise the control system and to detect possible leaks. The analyses are incorporated into our life cycle assessments and our DIN EN ISO 14001:2015 (environment) and DIN EN ISO 50001:2018 (energy) certifications. We don’t simply talk about necessary changes, we implement them in our environmental and energy action plans. Our goal: Detailed monitoring of all consumption by 2025.

Raising awareness – together we succeed

We attach great importance to raising our employees’ awareness and training them. To this end, we regularly organise environment weeks and informational events.
Our specialised in-house departments are actively involved in national and international professional associations in efforts to solve the major issues together with other experts. We have also incorporated sustainability issues as an integral component of our audits of subcontractors and suppliers. We are in the process of actively shaping the industry as it transforms. Our goal: sustainability monitoring of suppliers at 100% by 2025.

Recommendations and life cycle assessment – form follows sustainability

Maximising the minimum – saving resources is our utmost priority. We provide our customers with advice even in the quotation phase, and with sero, our CO2 calculator, we reveal possibilities for optimisation. Less is more – especially in the use of materials. We take care at the design stage to use materials in ways that keep them as homogeneous as possible, so the raw materials can be recycled at a high rate when the product reaches the end of its life cycle. We already maintain detailed material registers for many construction projects. But between production and recycling lies the service life, and in this longest period we offer building users outstanding maintenance of the building envelope. Our goal: Provide a material passport for our project to 100% by 2024.
