In a long-term project, together with Courage, we are investigating whether it is possible to determine volatile fatty acids, methane or acetone in the air blown from dairy cows. These substances are associated with health and digestion of the cow. We are working on a sensor together with tech partners …

The local Dutch legislations (PGS-29) regarding the above-ground storage of flammable products have become stricter. This has led to the phasing out of Viking-Johnson couplings that are located inside of tank pits. These couplings are prone to leakage and they use rubber seals which are now prohibited …

Design for a spa at the intersection of landscapes. With the sea level rise due to climate change, the traditional way of keeping the island save, by building dikes, will eventually become unaffordable. With farsightedness, twenty-five years ago an experiment with dynamic costal management was started …

Semi-closed greenhouses have been developed in which window ventilation is minimized due to active cooling, enabling enhanced CO2 concentrations at high irradiance. Cooled and dehumidified air is blown into the greenhouse from below or above the canopy. Cooling below the canopy may induce vertical temperature …
