Design

ingenhoven associates’ design philosophy is rooted in a holistic, systems-based approach that fuses environmental responsibility with human-centred spatial quality. Under its supergreen® framework, every project is conceived through lifecycle analysis – from material selection and energy-positive strategies to daylight optimisation and healthy indoor climates – ensuring buildings perform not only efficiently but also contribute positively to their urban and ecological contexts. Employing advanced digital modelling and performance simulation, the firm tailors form and structure to site-specific conditions, while prioritising biophilic connections and adaptable layouts that enhance occupant well-being. This integration of rigorous sustainability metrics, aesthetic refinement and technical innovation defines ingenhoven associates’ signature contribution to contemporary architecture.
ingenhoven associates designed the RWE Tower in Essen, a naturally ventilated double-skin facade high-rise building. Other low-energy office buildings by the office are the Lufthansa Headquarters in Frankfurt, the European Investment Bank in Luxembourg, the Breezé Tower in Osaka, 1 Bligh Street building in Sydney and the Marina One complex in Singapore.
