Project Description: (version fran莽aise ci-dessous)
The ability of greenhouses to capture solar energy is one of the key principles of passive solar design. Greenhouse technology offers many advantages for integrating food growing systems directly into buildings conceived principally for other purposes. In addition to potential energy savings, greenhouse spaces serve as buffer zones for habitable spaces, extend the growing season to improve yields, and allow the cultivation of delicate and exotic plants that may otherwise not survive in exposed conditions. Greenhouse technologies can also be combined with strategies such as hydroponics and aquaponics to further increase production.
The history of greenhouse technologies goes back to Roman times when various techniques were used to extend the growing season. The story of the technological evolution of the greenhouse is one of a gradual lightening of structures, increasing of spans and refining of materials. Recent decades have seen technological breakthroughs in glazing systems that improve thermal performance, reducing the energy consumption of modern greenhouses, lessening the need for heating or cooling to maintain consistent temperatures. Modern glazing systems can also reduce weight so that greenhouse systems can also be more readily integrated into, or on top of, buildings. Greenhouse systems are no longer restricted to using glass. A variety of plastic materials offer interesting opportunities and have been used widely in commercial greenhouse applications.
Greenhouse systems can range from the very simple, created from repurposed, found, or used components, to very sophisticated, state-of-the-art technologies. Designers of late have used their form to create ingenious spaces for urban agriculture that often contribute greatly to the built environment. New building forms and components such as productive double-skin facades suggest a new architectural language is evolving out of the integration of greenhouse systems with other building components and systems.

Description du Projet:
La capacit茅 des serres de culture 脿 capter l鈥櫭﹏ergie solaire constitue un des principes cl茅s de la conception solaire passive. Les technologies de la serre offre de nombreux avantages en ce qui concerne l鈥檌nt茅gration de syst猫mes de culture alimentaire directement dans des b芒timents con莽us avant tout 脿 d鈥檃utres fins. Outre les 茅conomies d鈥櫭﹏ergie qu鈥檌ls permettent de r茅aliser, les espaces sous serre servent de zones tampons aux zones habitables ; de plus, ils prolongent la saison de croissance, augmentant ainsi les rendements, et offrent la possibilit茅 de cultiver des plantes fragiles et exotiques qui ne survivraient pas n茅cessairement 脿 l鈥檈xt茅rieur. Afin d鈥檃ugmenter encore la production, on peut associer ces technologies 脿 des modes de culture telles que l鈥檋ydroponie et l鈥檃quaponie.
L鈥檋istoire des technologies de la serre de culture remonte 脿 l鈥櫭﹑oque romaine o霉 l鈥檕n se servait de diff茅rentes techniques permettant de prolonger la saison de croissance. Leur 茅volution s鈥檈st faite progressivement avec l鈥檃ll猫gement des structures, l鈥檃llongement des trav茅es et l鈥檃ffinage des mat茅riaux. Au cours des derni猫res d茅cennies, les avanc茅es technologiques dans la conception des syst猫mes de vitrage ont am茅lior茅 la performance thermique ; les serres modernes consomment ainsi moins d鈥櫭﹏ergie et les besoins en mati猫re de chauffage et de refroidissement afin de maintenir des temp茅ratures stables ont 茅t茅 r茅duits. Les syst猫mes modernes de vitrage permettent 茅galement un all猫gement des structures qui facilite leur installation 脿 l鈥檌nt茅rieur ou sur le toit de b芒timents. Le verre n鈥檈st plus le seul mat茅riau utilis茅 dans la construction de serres. Diff茅rentes mati猫res plastiques offrant des possibilit茅s int茅ressantes ont 茅t茅 largement employ茅es dans la conception de serres utilis茅es 脿 des fins commerciales.
Les syst猫mes sous serre vont de la structure tr猫s simple faite de composants recycl茅s, trouv茅s, ou d茅j脿 utilis茅s, aux technologies de pointe tr猫s complexes. Les concepteurs se sont r茅cemment servis de leurs formes afin de cr茅er des espaces ing茅nieux destin茅s 脿 l鈥檃griculture urbaine, qui apportent souvent beaucoup 脿 l鈥檈nvironnement b芒ti. Des formes et composants de construction r茅cents, comme les fa莽ades double-peau productives, sugg猫rent un nouveau langage architectural d茅velopp茅 脿 partir de l鈥檌nt茅gration de syst猫mes sous serre 脿 d鈥檃utres composants et syst猫mes de construction.
