General enquiries about Greenhouse Data Centres

From power and cooling to access, invoicing and certifications: we answer the questions that often only come up late in the process.

Greenhouse Datacenters is an independent, carrier-neutral data centre platform based in the Westland region. We offer colocation, connectivity and infrastructure for organisations that wish to retain control of their critical IT infrastructure. We manage the entire chain ourselves — from foundations and cooling to power and networking.

Our data centres are located in Naaldwijk, in the Westland region, in the Rotterdam/The Hague area (South Holland). You’ll benefit from a latency of less than 1 millisecond to Amsterdam, without the hustle and bustle and network congestion of the major hubs.

With colocation, you house your own hardware in our data centre and retain full control; the public cloud offers flexibility but less control; hybrid IT combines the two. We’ll work with you, with no obligation, to find the right balance to meet your requirements in terms of control, costs, compliance and scalability.

We work with IT service providers, MSPs, hosting providers, system integrators and organisations in the healthcare, finance and (semi-)public sectors. Our clients know what they’re looking for and, above all, want to be sure of one thing: that they can rely on us.

We manage the entire supply chain ourselves, and our engineers know every dependency down to the screw. We work with transparent, fixed prices with no small print, and we solve problems first before we look at where the responsibility lies. Fix first, settle later.

Yes. Greenhouse is an independent, European-owned data centre platform that is fully carrier-neutral. You always retain control over your choice of network — no lock-in, no hidden preferences.

Greenhouse Datacenters is an independent, carrier-neutral data centre platform in the Westland region. We provide the foundation for critical IT infrastructure: transparent, reliable and entirely under our own management. Your Digital Ground.

Greenhouse has been operational since 2013 and has maintained a 100 per cent uptime record since opening, with no unplanned downtime. We prove our reliability – we don’t just promise it.

Yes. Greenhouse is an independent, European-owned data centre located in the Netherlands. Your data is subject to European regulations and you are not dependent on US hyperscalers.

Greenhouse and Worldstream are deliberately separate entities. Greenhouse provides the physical, infrastructure-based foundation (multi-tenant data centres); Worldstream is our preferred connectivity partner for networking and services. The choice is always yours — Greenhouse is and will remain carrier-neutral.

It means that Greenhouse is the solid foundation underpinning your critical IT: stable, reliable and there when it matters most. Invisible in the foreground, but indispensable for everything built on top of it.

Greenhouse is led by an experienced management team and invests in capacity, energy efficiency and scalability. In doing so, we are building a platform that will remain reliable in the long term.

You’ll be working with people who understand your situation and who know you by name. No ticket-based system – just direct lines of communication with engineers and a dedicated point of contact.

Yes. Our engineers are on site 24/7 — actually in the data centre, not working remotely. They know every system in the building.

Yes. You work with people you know and who are familiar with your infrastructure. That keeps the lines of communication short and ensures a quick response.

The team consists of engineers and network architects with in-depth knowledge of infrastructure, networks and operational continuity. As we manage the chain ourselves, they have a detailed understanding of every dependency.

Because there are always engineers on site and we work through direct contact rather than a ticket queue, we can act quickly. When incidents occur, our approach is: resolve first, then investigate.

Greenhouse works with a carefully selected group of partners specialising in networks, connectivity and technology. We operate on a carrier-neutral basis: no exclusivity, just quality.

Worldstream is our preferred connectivity partner for network design, scalable connectivity and remote hands. Preferred, not exclusive: the choice is always yours.

No. Greenhouse is carrier-neutral. You retain complete freedom to choose your network; Worldstream is an option, not a requirement.

No. We don’t believe in tying customers in with complexity or contracts. For us, carrier neutrality is an architectural choice, not a marketing term — you’re in control.

We select partners based on quality and reliability, not exclusivity. This creates an ecosystem that enhances your freedom of choice rather than restricting it.

Simply fill in the contact form and we’ll put you in touch with the right person within one working day — not a script, but someone who understands your situation. Would you prefer to call us straight away? That’s fine too.

We’ll put you in touch with the right person within one working day. We take contact seriously: the form isn’t the end of the process, but the start.

Yes. Trust is something you have to feel, not just read about. Come and visit us in Naaldwijk and see the facilities for yourself — book a tour via the contact form.

We are based in Naaldwijk in the Westland region: about 15 minutes from Rotterdam and 20 minutes from The Hague. Easily accessible by car.

Yes. Free visitor parking is available.

Questions about our data centres.

You don’t choose a data centre based on specifications alone. These are questions that often come up when customers want to host their infrastructure with Greenhouse.

Our data centres are located in Naaldwijk in the Westland region, a short distance from Rotterdam and The Hague. This means you’re in the FLAP region (Frankfurt, London, Amsterdam, Paris), but away from the hustle and bustle of Amsterdam’s data centre hub.

In the Westland region, you enjoy the benefits of the FLAP region — low latency and strong connectivity — without the network congestion and capacity pressures of Amsterdam. With latency to Amsterdam of less than 1 millisecond and available bandwidth capacity to support growth, it is a smart alternative.

You’re about 15 minutes from Rotterdam and 20 minutes from The Hague. Free visitor parking is available.

Yes. A guided tour tells you more than a brochure ever could. You’re welcome to visit Naaldwijk and see the facilities for yourself — simply book an appointment via our contact form.

Greenhouse operates several data centres in the Westland region and has spare power and expansion capacity. This means you can continue to grow with us, even if your environment expands in the future.

Latency to Amsterdam is less than 1 millisecond. Thanks to direct connections to backbone networks, you can also reach Frankfurt, London and Paris with low latency.

Latency to Amsterdam is less than 1 millisecond. Thanks to a direct connection to backbone networks, you can also reach Frankfurt, London and Paris with low latency.

Yes. Greenhouse manages the entire chain itself: from the foundations and the building to the power supply, cooling and network. Our engineers are familiar with every interdependence in the chain, right down to the individual screw. That gives us the depth of understanding needed to prevent problems before they arise.

Yes. Our data centres are built to a Tier III standard with N+1 redundancy in power, cooling and connectivity. This offers an optimal balance between business continuity and cost control, and has resulted in a 100 per cent uptime record with no unplanned downtime.

Our power and cooling infrastructure is designed with redundancy and is maintained entirely in-house. This enables us to deliver on our promise: no unplanned downtime since we opened in 2013.

No. Our site in the Westland has spare power capacity, whereas many data centres in the Randstad are facing grid congestion. This means you can continue to grow with us without the power grid holding you back.

Yes. There is scope in terms of power capacity and rack space to grow alongside your environment. We’d be happy to discuss in detail what expansion options are available for your specific situation.

Our PUE (Power Usage Effectiveness) is less than 1.2 — well below the Dutch average. For us, energy efficiency is a measurable fact, not a marketing claim.

Yes. Our data centres run on 100% green electricity. Combined with our low PUE, this means a demonstrably energy-efficient environment.

Yes, and for us, that really does mean neutral. You have access to two international carriers, ten connectivity partners, seven internet service providers and five internet exchanges. No lock-in, no hidden preferences.

Through Greenhouse, you have access to two international carriers, ten connectivity partners, seven internet service providers and five internet exchanges. We source additional services on your behalf where necessary.

If the carrier you need isn’t available, we’ll arrange the connectivity layer free of charge. Ask your account manager about the terms and conditions.

Latency to Amsterdam is less than 1 millisecond. A direct connection to backbone networks also ensures low latency to Frankfurt, London and Paris.

A connection to the IOEMA submarine cable network is currently being prepared. This will strengthen direct international connectivity from the Westland region.

Yes. You retain 100% freedom over your network choices. For us, ‘carrier-neutral’ isn’t just a marketing term but an architectural choice: you retain full control over your network strategy.

Access to our data centres is controlled by multiple independent layers of security. Only authorised personnel are allowed near your infrastructure, and every interaction is logged.

Only people whom you authorise yourself. Our engineers have access to the facilities, but not to your equipment, unless you specifically request it.

Every access movement is recorded and monitored. This means it is possible to trace who was where and when at any given moment — a prerequisite for organisations in regulated sectors.

A visitor passes through several independent layers of access control before reaching the vicinity of the server rooms. For us, security is not a feature, but a prerequisite.

Yes. Our approach is designed for organisations in regulated sectors — such as healthcare, finance and the public and semi-public sectors — where even a single incident is one too many. Our security measures are in line with our certifications.

You’ll be working with engineers who are familiar with your environment and can take immediate action. No call centre and no ticketing system as a first point of contact – just direct contact with people who know the building and your systems.

Yes. There is always an engineer on site at the data centre — not working remotely, but on site. Even at night, at weekends and on public holidays.

We make a conscious choice to maintain direct contact. Not because we can’t automate it, but because your infrastructure deserves it. You’ll get answers, not tickets in a queue.

When an issue arises, we sort it out first — even if it’s technically outside our remit. Then we work together to decide how to deal with it going forward. Sort it out first, then define the scope.

Greenhouse has a track record of 100% uptime: no unplanned downtime since it opened in 2013. We set out our commitments in a clear SLA, with no hidden clauses in the small print.

Yes. As there are engineers on site 24/7, you can contact someone who can take immediate action even at night, at weekends and on public holidays.

Greenhouse Datacenters is certified to ISO/IEC 27001 (information security), NEN 7510 (information security in the healthcare sector), ISO 14001 (environmental management), PCI DSS (payment card security) and ISAE 3402 (assurance on internal control). These are assessed annually by independent auditors.

Yes. Greenhouse is ISO/IEC 27001 certified, the international standard for information security. This means that our processes for protecting information are systematically organised and audited.

Yes. Greenhouse complies with PCI DSS, the security standard for processing payment card data. This makes our infrastructure suitable as a platform for organisations that handle payments, such as FinTech and e-commerce companies.

ISAE 3402 is an international assurance standard that demonstrates that our internal controls are demonstrably sound. For clients who undergo audits themselves, this provides valuable evidence.

Yes. Greenhouse is a Dutch data centre under European ownership; your data is fully subject to the GDPR and European regulations. You are not dependent on US hyperscalers.

Yes. Greenhouse Datacenters is NEN 7510-certified, the Dutch standard for information security in the healthcare sector. This means we provide a suitable framework for the secure processing and storage of healthcare data, such as electronic patient record (EPD) data.

Our certifications are validated annually by independent auditors. A certificate is a snapshot in time; that is why we also embed the standards into our day-to-day management practices.

Greenhouse prioritises energy efficiency as a design choice: a PUE of less than 1.2, 100% green electricity and a WUE of 0.5 L/kWh. For us, efficiency is a measurable fact, not a marketing claim — it reduces both your costs and our carbon footprint.

Our PUE (Power Usage Effectiveness) is below 1.2, averaged over a year — well below the Dutch data centre average. A low PUE means that a large proportion of the energy goes to your IT and very little is lost to overheads.

Yes. All our data centres run on 100% green electricity. Combined with our low PUE, this results in a demonstrably energy-efficient environment.

Our WUE (Water Usage Effectiveness) is 0.5 L/kWh. This means low water consumption per kilowatt-hour, thanks to efficient cooling systems.

We use state-of-the-art cooling systems and N+1 cooling redundancy, designed for efficiency. As we manage the cooling entirely in-house, we are able to continuously optimise both reliability and energy consumption.

Yes. Greenhouse is ISO 14001 certified, the standard for environmental management. This means that, for us, sustainability is a controlled, structured process rather than a vague aspiration.

Yes. Lower energy losses mean lower energy costs and a smaller carbon footprint. That is why, for us, efficiency is not an end in itself, but the logical consequence of infrastructure that we manage and optimise entirely ourselves.

Questions about solutions

From colocation and carrier-neutral connectivity to consultancy and bespoke solutions: discover which combination best meets your requirements in terms of control, growth, compliance and business continuity.

Greenhouse offers four solutions: colocation (your own hardware in our data centre), connectivity (carrier-neutral network choice), advice & support (collaborative planning with no hidden agenda) and bespoke infrastructure (custom power, cooling or your own cage). We provide the foundation; you set the direction.

Colocation involves housing your own hardware in a standardised, secure environment with guaranteed power, cooling and connectivity. Bespoke solutions are for situations that do not fit within a standard setup — for example, high power density, dedicated cooling or your own secure, enclosed space. Not sure what you need? We’re happy to discuss your options with you, with no obligation.

That depends on your requirements in terms of control, growth, compliance and budget. Our engineers and network architects will help you choose the right option from colocation, connectivity and bespoke solutions — with no obligation — without pushing you in any particular direction.

Yes. Most customers combine colocation with carrier-neutral connectivity, and add bespoke solutions or consultancy where required. It all rests on the same foundation: one location, one team that knows your environment.

Yes. Connectivity is one of Greenhouse’s core solutions: carrier-neutral, with two international carriers, over 10 connectivity partners and five internet exchanges. You can read more about it on the connectivity page.

The price depends on your choice: number of racks, power consumption, connectivity and any customisation. One thing is always certain: a price is a price. We operate on the basis of transparent, fixed rates with no hidden costs. Request a quote and you’ll know exactly where you stand.

You start with a chat, not a form. We want to understand your situation before we make any recommendations. Book a chat or a tour in Naaldwijk; afterwards, you’ll receive specific answers and a clear quote.

Our engineers and network architects work with you to find the right balance between public cloud, colocation and hybrid IT, based on your requirements regarding control, costs, compliance and scalability. We provide information and carry out comparisons, without pushing you in any particular direction.

No. For many clients, Greenhouse acts as a sounding board — for technical questions, strategic decisions or simply to run something past people who understand the subject. That’s not something we charge for; it’s just how we work.

Yes. You can contact our engineers and network architects with any technical queries, even outside the scope of your contract. Direct lines of communication, people who know you by name.

Yes. We’re there for you even if it’s not in the contract. For many customers, we’re more than just a supplier: we’re a partner who thinks along with you, even when things aren’t standard.

Our engineers and network architects have in-depth knowledge of IT infrastructure and are familiar with every dependency in the chain. Because we build, manage and optimise everything ourselves, we not only know how it works, but also where the critical points lie.

Not every environment fits into a standard colocation setup. Greenhouse offers bespoke solutions for organisations with specific requirements in terms of power, cooling, security or layout. We’ll work with you to find a solution if your situation requires it.

Yes. From additional power and specialist cooling solutions to bespoke security, monitoring and detection systems — we provide bespoke solutions tailored to the specific requirements of your environment.

Yes. Greenhouse supports high-density configurations of over 10 kW per rack. We will discuss the exact capacity and the corresponding cooling solution based on your requirements — a bespoke approach is our starting point.

Yes. For energy-intensive workloads, we offer high-density configurations of over 10 kW per rack, with bespoke power and cooling solutions tailored to your specific situation. We’d be happy to discuss exactly what your environment requires.

A bespoke solution starts with a conversation. Tell us what you need; we’ll give you an honest assessment of what’s possible, what it will cost and how we’ll go about it. We’re not quick to say something can’t be done.

The same applies to bespoke work: a price is a price. Once we’ve assessed your requirements, you’ll receive a clear quote with no hidden costs or conditions.
