Sustainably Goals Urges Architect To Build A Greenhouse Around Former Fruit Farm

Is it a greenhouse, is it an educational center, is it a former fruit farm? It is all in one. A former fruit farm in Gooik, Belgium, is now functioning as an educational center. As decided by the municipality of Gooik, visitors can now see the refurbished agricultural buildings enclosed within a greenhouse-like structure, this way learning more about the countryside of Belgium. Architect Jo Taillieu: "We wanted a generous building that could provide the necessary comfort to all users of the center, even in bad weather, and provide an anchor point for exploring the Pajottenland.” 

The old farmhouse had been used as an education center already for years, but the project became to big to be run by volunteers completely. That’s why the municipality bought it and realized further expansion plans.

"Paddenbroek is by no means inconspicuous. In the hilly Pajottenland region, landscape, nature, heritage, and culture have been closely interwoven for centuries. Maintaining that balance was one of the major goals," architect Jo Taillieu explains. "The farmstead and especially the outbuildings were in a bad state and unsuitable for achieving the intended objectives. The link with the context was almost non-existent. The first idea - a classic renovation - was discarded, as was a new building, because it was unrealistic and did not meet the task that could be expected of an educational and tourist center. We, therefore, opted for a roof that would cover the farmstead, the historic baking oven, and the space around it."

Sustainability was one of the main goals of the construction. The dilapidated outbuildings were dismantled and the farmstead and the baking oven incorporated, restored, and insulated with moisture-regulating wood-wool cement boards and loam. Only these rooms and the offices can be heated. Thus, heating costs are sustainably limited to a few cores in the building and not everything needs to be air-conditioned. Inside the unheated greenhouse, therefore, there is an intermediate climate. Visitors are sheltered from rain and wind and can still enjoy the magnificent view of the surroundings. Upstairs are two more multi-purpose rooms that can be used as meeting rooms.

According to Stefan De Clerq, one of the business managers of the greenhouse construction company, the challenge was mostly the size and complexity of the project, as the features of this construction did not allow for a basic model. We created a unique truss and steel construction where each step was carefully monitored. All steel components were produced in our own workshops. This challenge was brought to a successful conclusion by the close cooperation between our draftsmen, our production team, and the external architects. Our own typical aluminum profiles and glass, applied in the roof and wall, also contribute to the elegant appearance of this nevertheless quite robust realization."

The construction of a complex like that of Paddenbroek in a rural area is not obvious and initially met with the necessary reservations, as could be expected. The fact that the municipality was prepared to go along with the story of architect Jo Taillieu and project manager Dries Deleye, therefore, shows vision and insight. Now that the construction is complete, everyone agrees that Gooik has gained a valuable multipurpose center that responds to ecological sustainability and from which the residents can also derive maximum benefit.

Growing Upwards: Q & A on Vertical Farming

By Food Insight

OCTOBER 22, 2019

Over time, farming practices have evolved to use less energy, pesticides, water and other needed inputs to grow the foods we depend on.

A type of farming that recently has grown in popularity is vertical farming. Building off the base concept of how greenhouses operate, this agricultural system allows for large-scale farming to occur on vertically inclined surfaces. Fruits and vegetables can be grown without the use of soil or natural sunlight, and the produce is often able to grow faster than it does in a traditional farm setting. A key advantage of vertical farms is that they can operate in urban areas and don’t require wide-open land; their vertical surfaces can be easily incorporated into a city’s existing structures and buildings.

Vertical farming has now been used in locations where large-scale farming previously has not been possible, such as in urban spaces throughout Brooklyn, New York, and Chicago, Illinois. Vertical farming’s small land usage and positive environmental benefits have the potential to increase sustainability, lower food costs, and increase accessibility and food security across the country.

We’ve touched on vertical farming in previous posts, but to take a closer look, we caught up with expert Ricky Stephens, who works with Agritecture, a vertical farming, and controlled environment agriculture (CEA) strategist group.

Q: What is vertical farming?

Vertical farming is the growing of crops in an indoor/controlled environment setting, in vertical stacks. Typically, vertical farming is done without using soil as the main practice. Instead, vertical farming uses practices like: hydroponics (growing plants in sand, gravel or liquid, with added nutrients but without soil), aeroponics (growing plants with roots suspended in air and nutrients delivered in a fine mist), or aquaponics (using the waste produced by farmed fish as nutrients for hydroponically grown plants).

Q: Why do you think vertical farming is being used as an alternative to traditional farming?

The top reasons for using vertical farming that come to mind for me include:

1. Vertical farming uses significantly less water than traditional farming. Currently, global agriculture accounts for 70 percent of freshwater withdrawals (use of freshwater). Instead of using up so much water directly, vertical farming often utilizes indoor hydroponics to grow crops. Using a recirculating system to recycle water, indoor hydroponics uses up to 70 to 95 percent less water than would be used in a traditional outdoor in-soil setting.

2. Vertical farming also eliminates the need for pesticides while reducing hazards. By balancing the use of beneficial insects, having heightened biosecurity protocols, and being in a well-controlled indoor environment, vertical farms can operate pesticide-free.

3. Vertical farming reduces pressures on our overall land use and addresses our concerns surrounding land scarcity. Due to population growth and land degradation, we’re running out of arable land. Furthermore, with the over-development of certain urban areas into industrial-style buildings (factories, warehouses), there is a plethora of vacant and utilizable spaces in cities that are very close to consumers. These areas are suitable for creating controlled, crop-friendly environments that can further “eating local” efforts.

Q: Where do you see vertical farming being able to help our food supply chain from a supply and sustainability standpoint?

Vertical farming moves production closer to the point of consumption—this means potentially less food miles and increased vegetable access. Let’s take one example of a very commonly consumed and desired food item: leafy greens. Currently, 98 percent of the current U.S. leafy greens production occurs traditionally (as outdoor crops) in California and Arizona. Not only are these water-dense produce items grown in severely water-scarce regions, they are then shipped thousands of miles across the country (and sometimes around the world).

As an alternative, vertical farming can be very useful for the leafy greens industry. In fact, because vertical farming is indoors and unaffected by weather conditions, you can grow greater quantities of different types of leafy greens all year round. In turn, this food can be immediately injected into the local food supply, thereby increasing availability and decreasing food loss and food waste during transportation.

In the long term, vertical farms will increase the diversity of crop choices and become more focused on producing different varieties of highly nutritious and frequently consumed products like mushrooms and strawberries. Vertical farms will also play an integral role in our larger movement toward sustainability and supporting local and regional food systems.

Q: What advances do you think will occur/are needed for vertical farming in the next 5–10 years?

We need technology advances that allow normal people—not just tech entrepreneurs or those with monetary funds—to access fair financing for vertical farms. As it currently stands, vertical farming can be cost-prohibitive to launch and start. For vertical farming to become more widely implemented there is a need for innovations and advances that bring down the high initial investment costs. The good news is this has started happening in the greenhouse space already.

Q: What ag (agricultural) technology excites you the most and why?

Soon we will need to feed upwards of 9 billion people in this world. On one hand, ag technology must be better utilized by farmers. On a more global and sustainable level, any technology that will push us all towards a more circular economy is exciting.

Agricultural technology supported by circular economy principles will begin exploring new business models, processes, and bio-stimulants that will play a major role in transforming our food system to be less wasteful and more regenerative.

Q: Is there anything else you’d like to add?

My team travels the world educating the broader public on the importance and potential of urban agriculture every chance we get. We have organized several of our own conferences in New York and Atlanta. It’s energizing to be working in a field with so many people who are fueled by honest passion and the pursuit of positive change.

We thank Ricky for his urban ag insights and look forward to seeing how more farming advances like vertical farming can positively impact our food system. To learn more about Agritecture and vertical farming, check out the company’s website here at www.agritecture.com.
