Al Wahat al-bahareya, Egypt

Royal Herbs Farm Complex-Workers' Housing

Royal Herbs, Egypt’s cultivator, producer, and supplier of premium quality, all-natural healthy infusion, inaugurated the first ever certified green building for local workers, named ‘The Bahareya Village’, in an effort to give back to the community and promote a more-sustainable way of life for its employees. Incorporating only local labor force as well as material in its design, the sustainable facility, located near Baweety, Bahareya Oasis, is capable of housing up to 150 workers. The workers' housing building saves up to 58% of energy and 53% of water.


One of the project’s highlights is its approach to energy efficiency. All air conditioning devices were removed to reduce greenhouse gas emissions. The passive design of the building (i.e. building orientation, wall thickness, exterior colour, and ventilation) increased its ability to remain 8-10 degrees cooler in summer and warmer in the winter. A number of measures are undertaken in the building such as: reflective tiles for roof and outdoor paving is used, outdoor lighting full cutoff, proper disposal of construction waste in municipal landfills, recycling construction waste, waste segregation at source and reduced indoor air contaminants in the form of VOC (volatile organic compounds) that are harmful to occupants. The building also has a garden attached with organic fruits and vegetables.
