The ReYard House has been designed and built by Team Bosphorus for the Africa edition of an
international collegiate sustainable and energy efficient building competition ‘Solar Decathlon’. TeamBosphorus is-the first Turkish team competed in Solar Decathlon-including students and professors fromtwo well-known universities of İstanbul/Turkey; İstanbul Technical University and Yildiz TechnicalUniversity.
The team has been awarded at 3 categories in the competition; Innovation, Engineering andConstruction, Communication and Social Awareness.The team won the first place in the “Innovation” category because of being reusable and modular (easy tobuild) by combining local materials with today's technology and using microalgae technology in anarchitectural project. It is also in the first place in the “Construction and Engineering” category with itssoil panels which can be easily constructed with wooden modular structure and energy efficient /sustainable engineering systems.
As well as through the written and visual publications on online andsocial media channels during the preparatory process that spanned 1.5 years, their presentations andhospitality in the competition process and even the methods of transferring knowledge to the visitors andother teams’ members through gamification, Team Bosphorus gained the “Communication and SocialAwareness” award.Riad is the name typology of traditional soil based Moroccan house which re-minds the life of TraditionalTurkish houses with yards and open corridors.
ReYard as a name of our house consists of two syllables"re" and "yard". First syllable "re" means "again" and "recycle", second syllable "yard" refers to "courtyard"and Riad.The design of the ReYard House is inspired by both traditional Turkish and Moroccan architectural stylesand reflects the "art de vivre" of a modern 5-members Moroccan family.
For both cultures privacy has anutmost importance which shaped the architecture of the houses. Families generally spend their times in theyards, which are considered as integral parts of a living unit. This is the reason why comfort conditions ofthe yard is important.ReYard House courtyard is designed to be comfortable, shaded, comfortably humid space for the hot anddry desert climate.
The separator walls are designed to allow the wind through the yard to cool down thetemperature while limiting the visual contact from outside South and West facades of the house do nothave any transparent elements.Solar panels of ReYard House are inclined at 15 degrees with respect to earth on top of the woodencanopy for maximum efficiency.
This canopy protects the yard from the sun and ensures climate comfort. Italso captures and redirects wind into the yard where the evaporation from the algae pond helps to cooldown the courtyard.The rammed earth based and wooden framed panels are the fundamental building elements of the ReYardHouse. The walls of the House are brought together by connecting them side by side.
Bamboo sticks areused in between the inner and outer panels as insulating material. The house is designed as a modularsystem. The traces of the modular setup, which was constructed outdoors, are also observed in the interiorspace. The selected furniture and space setup created a modular and flexible interior. Garden furnituresmade by the team’s skilled product designers using waste pallets and residual rammed earth panels toreduce waste and minimize environmental impact of the house and the ecological foot print.What is also aimed in ReYard was mainly to reduce water and carbon footprints of the project by using amicroalgae-based advanced waste water treatment system.
Domestic wastewater coming from bathroomand kitchen, is biologically treated in Membrane Bioreactor. This operation gives us an advantage to useremaining inorganic nutrients in algae pond. This method provides an advanced treated reusable water forsecondary purposes.We produce organic fertilizers through composting using organic kitchen waste and microalgae biomass.Additionally, algae pond water which promotes plant growth, is used for landscape irrigation directly.In algae pond we grow microalgae which can be considered as tiny single-cell plants growing throughphotosynthesis.
Comparing to the terrestrial plants, growing in the same area, they are able to produce 5-
10 times more Oxygen through photosynthesis. So, the algae pond acts like a tiny forest in the courtyard of
ReYard and uptakes CO 2 from the atmosphere. Through these innovative systems we are able to reuse80% of our waste water to provide water supply.We used beneficial innovative HVAC systems for the ReYard house in order to reach maximum energyefficiency.
Plate type heat recovery unit provides night cooling for the living room whileSingle room heat recovery units with ceramic cartridges are used to cool down the fresh air aspirated intoliving room and bedrooms.The COP of the air source heat pump is increased by means of evaporative cooling where the higher HPCOP values at night makes it possible to store “cold water” in the accumulation tank.
Reyard house’scooling and heating demand is covered by an air source heat pump system with support of a thermalsolar system.During 2 year design period of the ReYard House, members of Team Bosphorus conducted numerous ofResearch and Development studies in their universities in collaboration with industrial sponsors.In the end, they ReCycled, they ReUsed, they ReInterpreted and they call it ReYard.Project Team:Team Bosphorus from TurkeyClient:Solar Decathlon AfricaLead Architects:Aslı Aldemir, Bekir Süleymanoğlu, Ilgın Yeşim Eldeş, Avni YılmazDesign Team:Aslı Aldemir, Bekir Süleymanoğlu, Ilgın Yeşim Eldeş, Avni Yılmaz, Onur Yılmaz, Ceren Çakar, Ege Nurcan, Serhan Kaya, Cem Fırat, Esra Kıygın, Fatih Seymen, Ayşe Yılmaz, Mustafa Demirel Clients: Solar Decathlon AfricaEngineering And Construction:İsmail Çelik, Tarık Ateşer, Recep Tuna, Ece Zeynep Kalyoncuoğlu, Seda Kundakçı, Ahmet Can Bölük, Özge Aslan, İrem Esen, Hamdi Ergök, Ali Uğur Tülüoğlu, Talha Öz, Batuhan Üzümcüoğlu, Merve Derinpınar, Erdem Akım, Ayşenur Uzaslan, Saniya Üstün, Berrak Ecem Ozan, Elif Nur Tepe, Rami Rafil Abdulwahhab Al-Samaraae, Merve Karamustafa, Derya DikbıyıkConsultants:Prof.
