Amman, Jordan
Oak Saraya- 8 Villas
The Oak Saraya residential villas consist of eight semi-attached residences with an operational carbon reduction of 88 tCO₂ annually.
The project earned an EDGE Advanced Green Building Certification by achieving:
51% Energy savings as compared to typical local practices by applying many measures including full thermal insulated exterior walls using green cellulose with special attention to detailing, highly efficient window glazing and framing, highly efficient heating and cooling systems and high reflective cool roofs. The rooms also maximize natural sunlight and airflow, reducing the need for lighting and air conditioning.
43% water savings as compared to typical local practices by applying many measures including, an on-site wastewater treatment plant, low flow plumbing fixtures, and an efficient irrigation system.
Further sustainability features include conserving natural resources by preserving all existing trees on site and using local materials.
