GROOF - Greenhouses to Reduce CO2 on Roofs


Project Summary

GROOF is launching a new call for projects and offers one year of coaching to pioneers located in UK, Ireland, The Netherlands and Germany.


All info HERE on the COACHING tab.

 

 

The GROOF (Greenhouses to reduce CO2 on Roofs) project is an innovative cross-sectoral approach to reduce CO2 emissions in the construction and agriculture sectors by combining energy sharing and local food production.

The idea is to use rooftop greenhouses as a tool to:

  • Recover actively (use of the ventilation system) and passively (insulation effect) the heat produced and otherwise lost by the support building in a horticultural production installed in a rooftop greenhouse,
  • Collect the CO2 produced by human activity and the activities of the support building to feed the plants,

Practically, the project facilitates the emergence of this type of greenhouse on the market by demonstrating and disseminating good practices to actors in the building and agricultural sectors that are favourable to the development of profitable and functional economic and social models.

The project specifically aims to:

  • Identify and reduce market access barriers (urban planning rules, technical regulations, insurance, etc.): GROOF teams studied the practices in different NWE countries as long as the local regulations. The interview of several pioneers such as BIGH (Belgium), Urban Farmers (The Netherlands), Universitat Autònoma de Barcelona (Spain) and others provided valuable information that will be used to produce guidelines for early adopters struggling with the implementation of CO2-cutting rooftop greenhouses.
  • Support the first users in the implementation of their project: 10 early adopters have been selected through an open call and are currently coached by GROOF experts. The success of those 10 different profiles will demonstrate the relevance of several business models involving rooftop greenhouses and is expected to inspire others. You can discover the early adopters here.
  • Experiment and demonstrate the effectiveness of the technology for a representative number of business and social models: GROOF is investing in four pilot projects, designed to prove the effectiveness and sustainability of models related to different types of buildings. They are located in France, Belgium, Luxembourg and Germany. You can discover them here.

The results of each activity will be openly shared on our international community on the online platform Construction21 where regional and national public authorities, SMEs and large enterprises, research centres and general public are invited to interact. 

This community also host a mapping of existing and planned rooftop greenhouse projects in the world. Each project leader is invited to fill in the information of his or her project in order to share it with the world and benefit from the community’s feedback.

Four Pilot Projects

The GROOF project is investing in four pilots, designed to prove the effectiveness and durability of the models related to different building types, in Belgium, Germany, France and in Luxembourg.

Read more on each project below.

 

→ Fermes de Gally - Pilot

Paris, France

Urban roofs remain a little exploited space on which agriculture can develop and provide sustainable solutions to food, economic and climate issues in the city. A new stage in this urban agricultural development is therefore to create greenhouses on the roof that are totally integrated into the building's flow: in particular heat, water and CO2.
In this context, our greenhouse project on the roof of the Ferme Urbaine de St Denis consists of the construction and operation of a productive vegetable garden of 360 m² on the roof of the office and workshop building of the Ferme de St Denis, an urban farm run by les Fermes de Gally. This project will produce hydroponic and substrate agricultural products sold locally, in addition to farm production in the ground.
The greenhouse will have to work in synergy with the support building. Its location on the roof offers the advantage of enhancing the flat roof surface and thus preserve the floor space for the activities of the Kersanté Farm of St Denis (FKSD in the following). This feature will also allow it to easily connect to the heating and ventilation network of the building to recover heat and CO2, contained in the stale air, necessary for the cultivation of plants.

Follow the project of Construction21: Ferme de Gally - FRANCE

→ Université de Liège - Pilot

Gembloux, Belgium

The urban greenhouse of the TERRA building is part of the WASABI platform which brings together in one location all the innovative agricultural production systems adapted to the city and in dialogue with biodiversity. The platform and the urban greenhouse is an institutional project supported by Gembloux Agro Bio-Tech and ULiège.

The urban greenhouse will have an area of ​​198m² and will be divided into three compartments dedicated to research, teaching and demonstration of innovative systems adapted to urban agriculture. The main compartment (132 m²) will be dedicated to research only and will host experiments related to urban agriculture (hydroponics, aquaponics and bio-ponics). The second compartment will be dedicated to the demonstration and experimentation of innovative systems, both for students and for other publics. The third compartment will be used as technical hall. The greenhouse will reproduce conditions suitable for temperate crops such as lettuce and tomato. This greenhouse will be characterized by an accurate climate control, the production system will be modular in order to grow different crops.

→ EBF - pilot

Bürstadt, Germany

The ebf pilot is a Sunlight greenhouse, which is a modern approach to the classical lean-to concept. It is a greenhouse which is focused on minimal energy demand and utilizing existing energy flows to achieve a year-round operation. In combination with an internally mounted photovoltaic shadowing system, the greenhouse is becoming the worlds first plus energy greenhouse.

The pilot will be installed on an old packaging hall of a former nursery which is now being reinstated by ebf to show how a futureproof and sustainable horticulture business can look like. It will unite modern plant production technics with a social aspect of creating a community starting from an early age. The rooftop greenhouse will be implemented in the whole operation harboring specialized plants like chili peppers which can be harvested all year. Furthermore, the schools and kindergardens of the surrounding area will participate in the operation. Here, they have the possibility to learn and share the knowledge for food production. This gives the opportunity to help people reconnect with food production and give them back the responsibilty for their own food security.

Follow the project of Construction21: EBF - GERMANY

→ SOTA - Pilot

Bettembourg, Luxembourg

The IFSB pilot project will be installed on the extension of its company restaurant. The size of the greenhouse will be 18 x 20 m. The rooftop greenhouse will be located near the training site and will house plants that can be used directly in the restaurant below.

Here, the idea is to integrate a food production greenhouse above a restaurant. A reconnection between local food production and people in order to raise awareness about their food. In addition, a corridor will allow visibility over the production area without disturbing it.

The connection to the building to recover CO2 and heat makes sense for the construction sector. Indeed, this sector in Luxembourg will thus be able to have a project integrated into the building allowing a recovery of CO2, a future challenge for this sector.
