Paul de Ruiter Architects designed the first two phases of the Mercator Technology & Science Park in Nijmegen. The Science Park aims to strengthen the regional economic structure and retain and attract high-quality employment through knowledge transfer from Radboud University to the business community. The park presents itself as a place of synergy between the interests of the region, the university, and the business community. Mercator I was designed as a business complex for research and development in the field of medicinal chemistry and therefore contains both office space and laboratories. The design principle was to create a clear and transparent building with a high-tech appearance that reflects a strong environmental awareness.
The design of Mercator I offers maximum flexible letting possibilities. Companies requiring office space with associated laboratory activities can rent both types of space on a single floor. Because the laboratory units are stacked synchronously with the office units, combined letting is easily feasible. This design allows for the provision of relatively small units without sacrificing individual identity and representation. Conversely, the decoupling of laboratories and offices creates the opportunity for countless other affordable rental combinations. The specific structure of the Mercator climate façade creates subtle light and a pleasant, calm, and healthy working environment.
With transparency and (technological) knowledge sharing as the guiding principles, a glass facade for Mercator I was the goal: openness and abundant light, air, and views for its users. Because there was no budget for a traditional climate facade for this building, Paul de Ruiter Architects developed the "Mercator Climate Facade." The Mercator Climate Facade consists of an outer pane of floor-to-ceiling insulating glass and an inner pane of roll-up sun protection fabric. When the fabric is lowered, an air cavity is formed into which air from the offices is extracted via a central ventilation system. The heat is reused to heat the building, and the extracted air is reused to exhaust the laboratories.
The Mercator II design distinguishes three types of facades, specifically designed with solar orientation in mind. To minimize cooling within the building, the south facade is largely closed. The east and west facades are 50% open and feature windows fitted with aluminum louvers as permanent sunshades. The cool north facade is entirely glazed and offers optimal views of the surrounding park. These facades prevent additional solar heat gain while simultaneously allowing sufficient daylight to enter, enhancing the working environment.
The design of Mercator I and II prioritized energy efficiency and the architectural character of both buildings. Mercator I, with its fully glazed climate-control façade, is a bright and transparent building that provides the desired technological presence and contributes positively to the working atmosphere and energy efficiency. Its flexible design offers many future possibilities without compromising its identity. Mercator II also paid significant attention to energy efficiency and sunlight quality, making both buildings a valuable development for the Science Park.
