Performance of World Health Organization as a Green Building
The rapidly growing world energy use has already raised concerns over supply difficulties, exhaustion of energy resources and heavy environmental impacts. The global contribution from buildings towards energy consumption has steadily increased. Jordan relying on importing more than (97%) of its oil needs. The household in Jordan consumes 43% of the total electricity produced. The current situation enforces us to have more efficient use of energy in this sector. For this reason, energy efficiency in buildings is today a prime objective for energy policy at national and international level. The Jordanian buildings codes such as the Jordan green building code were developed to face energy challenges that Jordan has recently encountered. In residential sector, energy is used for equipment and appliances that provide heating, cooling, lighting, water heating, and other household demands. In this study, an efficient energy building has been selected and studied. The present study concentrates on the one of the energy saving examples, which is Green building represented in the World Health Organization (WHO) building in Amman. A comprehensive study of energy consumption in the building has been carried out. A comparison between the Jordanian regular buildings and the current building was made; EnergyPlus was used to make all calculations. It is found that the WHO building saves 23.9% of the total energy saved from HVAC systems, and widely dependent on the natural lighting. WHO reduces the Greenhouse gases emissions of CO2, about 57563.12 kg of CO2 were reduced, which helps in the global warming.
