GROOF - Greenhouses to Reduce CO2 on Roofs


Project Summary

The GROOF project is an innovative cross-sectoral approach to reduce CO2 emissions in the construction and agricultural sectors by combining energy sharing and local food production. The idea is to use roof greenhouses as a tool for:
   - recovering actively the produced and not consumed heat generated and otherwise lost by the building that supports the structure (through the ventilation system) and passively (30% heat lost through the roofs on average) in vegetables and herbs production,
   - collect CO2 produced by human activity and building activities to "feed" the plants,
   - reduce transport-generated CO2 emissions by producing plants locally.  The greenhouse itself is an extra activity located outside of the building but sharing energy with it in order to make both of the structures more efficient.

Concretely, the project will facilitate the emergence of this type of greenhouse on the market by demonstrating and disseminating among the actors of construction and agriculture good practices favorable to the development of profitable and functional business and social models.

The project will aim specifically at:

   - identifying and reducing barriers to market access (urban planning rules, technical regulations, insurance, etc.),
   - supporting first users in the implementation of their project,
   - experimenting and demonstrating the effectiveness of technology for a representative number of business and social models. The results of each activity will be shared with the target communities (e.g. regional and national public authorities, SMEs and large companies, research centers).


GROOF will invest in four pilots, designed to prove the effectiveness and durability of the models related to different building types. GROOF will then launch this solution on the European market.

On September 24 and 25, 2019, the jury of GROOF experts in construction, energy, vegetable production, business model gathered to analyse the various applications that will benefit from the first part of the one-year coaching, from September 2019 to September 2020, to help them build, develop and implement their rooftop greenhouse.

The group has decided to select 10 projects located in France, Belgium and Luxembourg that aim to reduce the impact on CO2 emissions by building a rooftop greenhouse. These projects bring together different techniques of greenhouses: hydroponic greenhouses, aquaponics, vegetable gardens in-soil, etc. As well as different types of greenhouse projects : educational, social, private, etc.

How rooftop greenhouses can reduce the environmental aspect of horticulture

Posted on

Sealing ground is a problem which negatively impacts the water balance since the soil cannot be used as a water puffer anymore. This results in surface water not being able to be added to the groundwater level which can directly lead to flooding. On the other hand, this water does not get added to the groundwater which can have severe consequences for the quality of the groundwater and the actual amount. Lacking groundwater will lead to more concentrated toxic substances and in the far run to possible draughts. Read More

Increase building's attractivity

Posted on

A rooftop greenhouse (RG) is not a simple agricultural production tool. It is a way to increase the whole building value, and to show your interest in modernity and ecology. Rooftop greenhouse can be used to product fruits and vegetables only, in an intensive way, or can also be seen as a place for people to meet and exchange. Read More

What expertise do you bring to GROOF project?

"We offer knowledge in circular economy and material flow management, especially in regards to energy and resource efficiency and management. HS-Trier/IfaS has also an expertise in environmental assessment methodologies, such as greenhouse gas emission accounting, in order to contribute to the identification of potentials to improve buildings’ environmental performance. Thus, we contribute to GROOF with technical support including technical monitoring of CO2e performance in order to maximise emission savings."

Thomas Anton: Hochschule Trier Institut für angewandtes Stoffstrommanagement, Germany

"Innovation, sustainability, health, three key words representing the impact of GROOF project!"

Pierre Raulier, Project Manager, Centre de Recherche en Agriculture Urbaine, Université de Liège, Gembloux Agro-Bio Tech, Belgium

Quelles seraient les principales raisons pour un développeur de projet d'installer une serre sur toit ?

"Au Luxembourg, un maître d'ouvrage pourra se convaincre de faire une serre sur le toit de son bâtiment en prenant en  compte les arguments suivants :

  • utiliser et rentabiliser un espace perdu
  • augmenter la performance de son bâtiment grâce à un système qui isole, voir chauffe son bâtiment tout en s'autofinançant
  • apporter une plus value dans la vie sociale des bâtiments de logement ou tertiaires."

Marcel Deravet - Sustainable construction project manager, Institut de Formation Sectoriel du Bâtiment, Luxembourg

What were the motivations of the Universitat Autònoma de Barcelona (UAB) to get involved in GROOF project?

"Transfer knowledge accumulated during the last ten years of work and research within ICTA-UAB in urban agriculture in southern Europe. Also, help promote Urban Agriculture in cities and, in this way, reduce CO2 emissions in buildings and make horticultural production more circular."

Xavier Gabarell Durany, Projet Leader, Universitat Autònoma de Barcelona, Spain.
