Steered since January 2016 in the French region of Provence-Alpes-C\u00f4te-d\u2019Azur with the aid of Geres, the Agrithermic consultancy<\/a> and Groupe de recherche en agriculture biologique (GRAB)<\/a>, the concept of bioclimatic greenhouses is attracting more and more attention from growers. Both ecologically sound and economical, a bioclimatic greenhouse can regulate itself using the sun’s energy. By early 2020, 685 m\u00b2 of greenhouses were finalized, with six pilot operations using five different technologies. Principles and testimony.<\/p>\n

Proof of the growing enthusiasm: last March, some sixty professionals, producers, budding nursery operators and students from the region showed up during a visit organized by Bio de Provence<\/a> under the bioclimatic greenhouse of Marie Moyet, owner of an organic nursery in Aubagne.[\/et_pb_text][et_pb_text _builder_version=”4.4.2″ min_height=”572px” custom_margin=”||3px|||” custom_padding=”0px|0px||0px||” custom_padding_tablet=”|0px||0px” custom_padding_phone=”” custom_padding_last_edited=”on|tablet” link_option_url_new_window=”on”]<\/p>\n

The aim, as explained by Marc Glass, Energy project officer at Geres and the main speaker on that day, is to “capture<\/u>, store<\/u> during sunny periods and finally re-radiate<\/u> the heat during the night and cloudy periods”<\/em>.<\/p><\/blockquote>\n

“It’s now four years since I began operating with a bioclimatic greenhouse and, in my case, the system helps me to ensure earlier plant growth, secure my production and, more broadly, keep my business going”.<\/h3>\n

\u2026says Marie, who specializes in vegetable seedlings, beneficial flowers and herbs, working with professionals.<\/p>\n

“There is an element of security for operators too” <\/em>adds Marc Glass, who is also in charge of the whole thermal component of the project (\u2026) If it freezes in a traditional greenhouse, someone may have to go out at night to regulate the heating. With a bioclimatic greenhouse, operators can sleep easy because frost is virtually non-existent.” <\/em><\/p><\/blockquote>\n

Genesis of a 100% eco-responsible farming model<\/h2>\n

To find the origins of this ingenious idea, you have to travel to northern Asia and especially the Himalayas.<\/p>\n

Faced with very cold temperatures by night (as low as -20\u00b0C in winter) and exposed to very high levels of sunshine by day, the region decided in the 1990s\/2000s to redynamize classic greenhouse production by offering a model based on the passive aspect of the sun. Result: growing then becomes possible courtesy of the re-radiated solar heat, even when the night-time temperature outside is cold.<\/p>\n

A decade later, the concept slowly began to take hold in southern France. It was the turn of the Provence-Alpes-C\u00f4te-d\u2019Azur region to have a go. And it’s working.[\/et_pb_text][et_pb_image src=”https:\/\/www.geres.eu\/wp-content\/uploads\/2019\/10\/07-Visite-serre-bioclimatique-MMoyet-MGlass-040320-.jpg” _builder_version=”4.4.2″ min_height=”459px” custom_margin=”25px||46px|||”][\/et_pb_image][et_pb_text _builder_version=”4.4.2″ min_height=”267px” custom_margin=”||3px|||” custom_padding=”0px|0px||0px||” custom_padding_tablet=”|0px||0px” custom_padding_phone=”” custom_padding_last_edited=”on|tablet” link_option_url_new_window=”on”]<\/p>\n
