|Dear Colleagues and Students,|
To further promote energy conservation awareness to faculty and students, and encourage everyone to develop good habits of energy conservation. In 2017, Energy began a feasibility study on energy-saving renovation of public area in the university, especially in the pantries. Considering that the general use time of the pantry is not long, the air conditioner is still being turned on for a long time when nobody there, which may cause unnecessary waste. To this end, with the support of the Student Resources Section, starting from October 2017, the Energy Section launches the renovation work of air-conditioners by phases in 52 pantries at PGH (S1 to S4). The main purpose of this project is to maintain a balance between good ventilation and energy saving in the pantry. Therefore, the original air conditioner is disassembled and replaced by a high air volume fan, which not only meets the actual needs but also saves energy. The next stage of this measure will be extended to the pantries in Residential colleges.
Energy saving information:
It refers to the natural air flow caused by the difference in air pressure or temperature difference between the air inside and outside the building without using any mechanical equipment. In addition to reducing energy consumption, it also enhances indoor air quality and comfort through natural ventilation. Natural ventilation can generally be divided into the following two types:
Due to the pressure difference caused by natural wind acting on the building, which drives the air exchange between indoor and outdoor.
Due to the density difference caused by temperature, difference between interior and exterior air, which forces upflow buoyancy and drives the air exchange.
Therefore, please try to enjoy natural ventilation instead of mechanical ventilation while outdoor temperature is suitable. It can not only improve the indoor air quality, but also contribute to energy conservation.
