GreenBuilding project promotes the use of renewable energy sources and energy efficiency measures in public buildings. The project will support 3 cost-effective public buildings energy refurbishment in Greece, Tunisia and Jordan. One of the energy refurbishments will take place at the Greater Irbid Municipality in Jordan.
Greater Irbid Municipality main building is more than twenty years old (1992) and located in the old city center.The municipality building consists of seven floors including employees parking. This building includes most of the main departments of the municipality, which is often crowded during working hours (thirty six hours per week).
The building is located in Jordan. Greater Irbid Municipality is responsible for this pilot case.
The building has several meeting rooms and a large main hall for ceremonies and events. There are different departments that wokr from eight hours to ten hours per day. This building contains a computer center for training and development, equipped with about forty computers, printer, five (5) meeting rooms, served by lighting, cooling and heating systems and a large main hall (theater) for celebrations and large events.
- Number of employees: 618 persons
- Number of citizens/visitors: 380 persons/day
The lighting system of the building is mostly fluorescent with narrow use of LED.The building contains a central heating system, often used in the very cold months, consuming ca. 18000 liters/year. This rate varies by weather conditions and low temperatures. Electric heating units, or electric heaters (candles) at other times, are used for heating.
A review of consumption of electricity throughout the year shows that lower consumption periods occur when the temperature is average and use of air conditioning or heating is not required. According to the consumption analysis, lighting has the highest contribution, accounting for 76% of total consumption. The Schiller system is used for cooling at capacity of 120 tons and cooling units (2 tons thermal) distributed over the building (feeds: 60 units). Sixty percent of cooling uses inverters. Central heating system on bio-fuels is often used in very cold months and consumes ca. 30000 liters/year. The current heating system is based on five gas boilers, two hot water generators, ten solar heaters. Cooling is based on four air conditioning plans, about 300 splits, and two rooftops.
Municipality of Greater Irbid addresses the high energy consumption by developing a Sustainable Energy & Climate Action Plan (SECAP).
