the InterHouse prototype winner of the solar decathlon Africa 2019 contest

the InterHouse prototype  boasts the following features:

Architecture and construction

-architecture concept to benefit from the sun path and optimize natural sunlight

-compact envelope to limit heat transfer

-cross ventilation windows for night cooling and indoor air quality control

-a courtyard that acts as a buffer space to the main entrance of the house

-a green wall for evaporative cooling

a bioclimatic pergola with rain and wind sensors to protect the courtyard and to control the amount of sunlight that gets in 

-45cm thick CSEB (compressed stabilized earth bricks), made locally, with a high thermal capacity that contributes with the slab on grade to modulate the indoor air temperature

-20 cm of straw for the roofs thermal insulation

HVAC

-in-house made smart system monitoring the indoor environment quality, air temperature & humidity, lighting, CO2 and VOC

-Smart control of the ventilation system

-Smart control of the windows blinds

-Data monitoring via internet

Energy & electricity system

PV Solar panels : 4kWp rooftop PV panels & & 1.6

kWp semi-transparent BIPV (building integrated photovoltaics)

– South-East oriented BIPV panels act as sun protection of the seating beneath it from rain and summer overheating.

– 5kWh, 48V recycled electric car battery system

Wastewater Treatment & Rain Water Collection

– Wastewater treatment system: phyto-purification and UV purification filtration of grey water (dishwasher and kitchen sink).

– Filtred water collected in a tank along with the rain used for cleaning and for watering the landscape and green wall.

along with winning the solar decathlon Africa 2019 contest the interhouse prototype in built in Benguerir won many sub contests : 

1st place in electrical energy balance

2nd place in innovation contest

3rd place in market appeal

4th place in engineering and construction
