In the Netherlands, 55% of Dutch offices will not pass the energy rating certification of label C that will come into effect in 2023. Moreover, the country is currently experiencing a housing crisis with over 1 million homes needed by 2030. As such, MOR is developing a renovation strategy to renovate underperforming office buildings into net-positive, multi-purpose buildings that are contributors to their environment and catalysts for activities and social interactions. The building is flexible to programmatic changes and adaptable to the inhabitants’ needs over time by way of a modular design from the interior modules to the photovoltaic facade tiles on the exterior, as well as through the use of design for disassembly methods. By using prefabrication methods with an economy of scale, MOR is able to offer these housing units at affordable prices for starters (young professionals, age 25-35). Starting from here, MOR aims to create a future-proof built environment that gives more to its surroundings than what it takes away from it. As a case study for the project, the Team decided to refer to the Marconi towers in Rotterdam, a typical 1970s office typology located in an area currently being transformed into a new makers district.
MOR’s renovation proposal achieves a net-positive footprint:
The facade tiles are coloured solar panels designed for easy assembly/disassembly, serving a practical and aesthetic function.
A Helophyte filter system treats waste water to be reused for toilet flushing and irrigation by using. The system first separates the waste from the water, then purifies it with bacteria working together with helophytes to eliminate the contaminants.
The Green Wall is both an architectural feature and important to the climate strategy. The incoming air is filtered through the plants as it enters the home. Behind it, salt-based PCM help pre-heat the air in the winter and pre-cool it in the summer: minimising the reliance on the more taxing technical systems.
A 5m-long PCM battery is used to intelligently increase the performance of the air heat pump.
