This dissertation will focus on the greenhouse vegetable horticulture sector of the Netherlands, and will investigate how Dutch greenhouse companies can benefit from the relationship with Poland. Currently, the export of the Dutch greenhouse vegetable has decreased and the sector is experiencing the …

The way we live is not efficient. We waste, we barely recycle and the facilities we use are wasteful. The reason is the large scale in which we facilitate ourselves. This also happens in and around Arnhem and Nijmegen. The way of living in the sphere between the rivers Waal and Rhine has to alter drastically. …

There are several greenhouses built with solar panels integrated into the roof. In summer time this will operate very well, although broad shadow stripes can result in growth and yield differences. In winter the amount of sunlight is further limited by the solar panels and will result in further reduction …

The objective of this concept is a significant reduction of energy consumption in greenhouses and buildings with large facades and windows by using available solar energy. The scope of this investigation is to study the advantages of a building integrated CPV system. The basic idea is that a larger fraction …

A lot of energy in the Port of Rotterdam is getting wasted by power plants or other petrochemical companies. This waste energy can be reused. The assignment of this feasibility study is how a technical design concept of an integrated district heating process is applicable in the Westland. This thesis …

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 …

In this paper the design and development of a new type of greenhouse with an integrated filter for reflecting near infrared radiation (NIR) and a solar energy delivery system is described. Especially the optical parts as the spectral selective film, the properties of the circular reflector and the efficiencies …

Bergerden Agropark is a greenhouse zone area in province of Gelderland in the Netherlands. The local government, municipalities Nijmegen and Arnhem, is the owner of the land and it invested a lot on sustainable energy system in Begerden Agropark. The greenhouse entrepreneurs built new and modern greenhouses …

A (semi-)closed greenhouse is a novel greenhouse with an active cooling system and temporary heat storage in an aquifer. Air is cooled, heated and dehumidified by air treatment units. Climate in (semi-)closed greenhouses differs from that of conventional open greenhouses. The aims of our research were …

A new type of greenhouse with linear Fresnel lenses in the cover performing as a concentrated photovoltaic (CPV) system is presented. The CPV system retains all direct solar radiation, while diffuse solar radiation passes through and enters into the greenhouse cultivation system. The removal of all direct …
