Prominent project for sustainable school construction with a consistently climate-friendly approach

In northern Essen, on the site of a former sports field, a six-track comprehensive school with a three-court sports hall and two single-court halls is being built. On approximately 34,000 square meters, a state-of-the-art and sustainable school campus for around 1,300 students and about 130 teachers will be created. In addition, new spaces for district use are planned. The surrounding open spaces will be designed as public space according to the “School in the Park” concept and will serve as a district center for both students and residents. The site is owned by the City of Essen and is crossed underground by an underground railway line.

The new school building is intended to meet the current requirements of a Passive House standard. The client aims for BNB Silver certification (Sustainable Building Certification). The innovative energy concept envisions fully renewable operation with geothermal energy, heat pumps, and photovoltaic systems. About 2,100 m² of photovoltaic modules will be installed on the building’s green flat roof, covering around two-thirds of the electricity demand. Geothermal warmth is supplied by two heat pumps (ground-source heat pumps) - they provide heating to the building, and in summer the boreholes are used for passive cooling. In addition, an air-to-water heat pump is planned, enabling even more flexible year-round climate control. A total of 46 geothermal boreholes are planned with depths of 150 to 180 meters. Sustainability is central to this new construction in Altenessen-Süd and shapes all planning disciplines. A significant contribution to achieving the ambitious sustainability goals comes from our MorgenGrün brand – Innovations by ZWP. The MorgenGrün team accompanies and ensures compliance with sustainability requirements according to BNB (Sustainable Building Assessment). This certification ensures that sustainability is embedded in the building’s entire life cycle. The focus is on minimal energy consumption, prudent water use, materials from renewable resources (e.g., wood-hybrid construction), pollutant-free materials, recycled materials, and the highest level of user comfort.
