1. Building geometry layout data was put to the Design Builder soft-ware. These data was extracted from the designed drawings and technical specifications;2. Characterized the building’s architectural elements (roofs, external walls, windows, ceilings, internal partitions, and doors, etc.)and then characterize their thermal properties;3. Specified the building’s utility supplies and thermal equipment in the energy model;4. Performed the monthly energy simulations for the studied green building.5. Performed the hourly energy simulations for a typical week in summer (July 7th 00:00 a.m. to July 13th 00:00 a.m.) and winter(January 13th 00:00 a.m. to January 20th 00:00 a.m.) according to the weather data translator in Design Builder
