Vyverberg helps entrepreneurs in horticulture realise their dream…
Being an independent consultancy, Vyverberg guides entrepreneurs and investors with complex investment projects in the (inter)national food and horticulture sector. In these projects our main focus is on economically sound operational management and on contributing to a sustainable world.
A complete construction project, from idea to a fully functional greenhouse, can sometimes have a very long lead-time. This is due to factors such as redevelopment and requests for permits and subsidies. In some cases a project can take several years. Vyverberg has the experience and the expertise to efficiently manage such an extensive project, ensuring that entrepreneurs can fully concentrate on running their company. We divide such projects into three phases.
Vyverberg can produce the design for both renovations and new builds. Your wishes are our starting point and we factor in development plans, permits, the Building Inspectorate and building requirements. Besides the greenhouse itself, the working space, technical installations and logistic processes can also be incorporated into the design. Vyverberg carries out the feasibility study and takes care of the construction estimates and budget. In addition, we can help set up requests for funding and subsidies.
We specialise in independently managing multiple parties, where some may have conflicting interests, in a professional manner. Prior to construction we have a preliminary technical consultation with all contractors and installers. We oversee the process of preparing the land for development and draft a Health and Safety Plan. In this phase we supervise the construction, chair construction meetings and inspect the project’s progress and execution on site. Lastly, we supervise the setting up of all installations and take care of project delivery.
Vyverberg offers a wide range of additional services. We carry out measurements and write the reports that are needed for requesting permits or certifications. Vyverberg can set up models to predict future energy and water usage, making future costs clear, to support you in your business planning and future investment strategies.
In addition, we are a registered valuer of horticultural businesses.
Project building blocks
In addition to the process lay-out of a construction project, Vyverberg has also clearly visualized the physical components of a greenhouse. The interdependence of each part on another can produce a complex puzzle. Vyverberg can support you with every part, including when you choose a selection of building blocks. We distinguish twelve building blocks, which are briefly explained below.
Preparing land for building is an important basis for a successful project. Various investigations, like probing and soil tests, must be carried out for both the technical detailing and the permit process. In addition, the zoning plan may also require additional investigation.
Various parties will need to lay pipelines and cables in the ground, which are inventoried in a utility plan beforehand. At this stage an examination of whether the installation requirements match the (public) utilities is required. Facilities must be strategically placed to allow for future additions.
The front building usually is a combination of appearance and functionality. Logistics and office functions should support both the produce and the workforce. The building must also comply with insurance requirements and (local) legislation.
No cultivation space is identical. Greenhouses are designed for a specific crop and to provide a balance between growing space, technical installations and energy supply. Naturally, customer requirements must also be taken into account.
Electricity is a complex factor in the overall planning. Ground cabling must be done during excavation work early in the project. Other electronic components like sensors and computers can only be installed at the very end.
Screen systems for cultivation with artificial lighting differ from energy conservation screens or light reduction screens. Furthermore, when installations are hard to reach, it’s important to opt for screen systems with better protection.
A greenhouse must be provisioned for an optimal cultivation climate, with energy consumption of heating and cooling installations kept to a minimum.
Irrigation systems are truly custom solutions. Innovative irrigation methods create the perfect growing environment for each crop, whilst producing minimal waste water. In this, local legislation is also an important factor.
Every cultivation has its own lighting strategy. It’s not just the right amount of light or color spectrum, but the heat generation of the light fixtures which has to be taken into account as well. Also the availability of electrical power is important for the choice of fixtures.
Every cultivation requires specific installations and facilities. This is taken into account in an early stage of glass house design. For instance, hoistable heating frames need a different glass house construction than cultivation on tables.
The supply of energy becomes increasingly important for the operational management of greenhouses. Besides well-known power sources like solar and wind, bio, cogeneration, geothermal and gas, there are new alternatives such as heat pumps, thermal energy storage (TES), and even power generation from nearby ditches.
It’s a challenge to find the best combination based on an ever changing kWh price and legislation. Vyverberg can draw up a thermal profile that calculates with multiple options, to ensure an optimal mix of facilities.
During the design phase, we chart the complete project. Unforeseen circumstances and progressive insight can be valid reasons to change the design in the build phase. With proper documentation throughout the whole process, the build phase stays organised and an ‘as-built’ document can be produced after completion.
Vyverberg is very proud of its broad range
of clients and projects
of clients and projects
We work with many types of horticulture, both in the Netherlands and abroad. We advise on construction projects ranging from 50 square meters to many hectares, with our activities varying from valuations to managing an entire new construction project.
Vyverberg has a lot of experience with energy technology such as cogeneration, heat-cold storage, solar and wind power, bio-energy and Son-T and LED lighting. We can give you a clear insight into your energy consumption and determine the ideal combination of energy technology for your company.
Vyverberg believes it is important to be at the forefront of knowledge and innovation. In this context we work according to the current ISSO 86/87/88 standards, ensuring we are safer, more sustainable, future-proof, more knowledgeable; in short, better.
In addition, we are proud to be the first consultancy bureau in the horticulture sector to be HortiQ certified, back in 2018. This proof of craftsmanship is a guarantee that clear procedures and criteria are followed during the construction process. This quality mark has been drawn up by AVAG, the organization of the Dutch greenhouse construction and installation sector.

Vyverberg operates internationally with a focus on Europe, driven by an increasing demand for local and sustainable produce from (glass) greenhouses.
Sustainable horticulture succeeds when it is profitable for every partner in the supply chain. The corresponding investments require a clear, long-term vision. By focusing on the circular use of commodities and energy, and by optimizing logistics, we ensure that the consumer receives a responsible product in optimal condition.
Vyverberg plays a pioneering role in horticulture. Our expertise links practice and theory, and embraces separate fields such as logistics, energy, technology and finance. We are not bound to suppliers, we work in accordance with all legal guidelines and we are the first certified horticultural consultancy firm in the Netherlands. Together with our clients we contribute to a field that, on a global scale, is at the forefront of innovation.
