Part 1
“Energy conservation has been a major concern in the recent decades. There are critiques that buildings.in Hong Kong has been too much relying on use of air conditioning to maintain a pleasant indoor environment. Since air conditioning systems consume a lot of power supply, consequently most of the buildings are not regarded as environmental friendly.” Evaluate the above statements. From the perspective of an architect, discuss how a residential building may be designed to reduce energy consumptions.

In the recent decades, the issue of global warming triggers a heated debate. Global warming refer the phenomenon that
This can alleviate heat island effect and make the urban landscape more pleasant. Also they install the hybrid chiller system to improve the air quality. It highly concern about the reduction energy consumptions.

On the other hand, lighting is another main factory that controlling the Building Energy Efficiency. According to the Electrical and Mechanical Services Department (EMSD), the electricity consumed by lighting in residential sector in Hong Kong usually account for 24% of the total consumption respectively. It is the second highest electricity consumer following air-conditioning. Therefore, the use of energy-efficient lighting system is important in order to reduce resource wastage and enhance the effectiveness of energy use.

In our daily life, we might less energy consumption light equipment, such as Light Emitting Diode (LED), Occupancy sensor, Scotopic lighting, Tri-phosphors tube, etc. But From the perspective of an architect, we should not only depend on the equipment, we could start from the nature design of the building. For example: using tinted large window for the resident to enjoy the nature of sunlight and save the energy for lighting in a sunny
The amount of light required is control by the size of the holes or windows. But in case of Hong Kong, architect should concern the direction of the declination of sun as Chinese much care about the angle of sun.

To conclude, energy consumption should be reduce due to the global warming. The Paris Agreement aims to holding the increase in the global average temperature to well below 2 °C above pre-industrial levels and to pursue efforts to limit the temperature increase to 1.5 °C above pre-industrial levels. From the perspective of an architect, we could also follow this trend. Below is a sustainable design demonstration extract from secondary school book.

Architecture and Nature interact with each other, there are no conflicts. Architect could appreciating the elements in nature and make use of the nature element in order to reduce the energy consumption. Good urban planning and sustainable design for the building regarded as environmental
