With the continuous progress and development of the construction industry, architects and engineers have introduced the concept of energy-saving and green building designs that utilizes less energy and electricity. This advancement in the construction industry has made green buildings more attractive, thanks to their low energy consumption also compliance with environmental and ecological requirements. This paper examines the principles and advantages of energy-reduction technologies for building heating, ventilation, and air-conditioning (HVAC) applications, and discusses the technical optimization measures for the technology.

Conditioning Control

About 7% of people’s daily time is spent in taking vehicles between office and home. Besides, with the improvement of the living standard in today’s society, people’s requirements for a comfortable environment inside the car are constantly increasing and this must rely on an effective vehicle air conditioner to maintain the comfort of the cabin environment. In general, a vehicle air conditioner uses the air-mixing mode to regulate the temperature control system. In this mode of operation, the compressor needs to work continuously, which is extremely energy consuming. The vehicle’s air conditioner is greatly affected by the inner and outer heat load, which are generated therein. Furthermore, the heat load is instantly changeable. Therefore, only when the controller can adapt to the feature of heat load, then we can find the optimal control method, thus enabling the vehicle’s air conditioner to interact with the actual heat load to supply the balanced cooling capacity and, as a result, create the most comfortable environment inside the cabin with minimum energy consumption. For this purpose, we bring up in this paper a low-energy-consumption smart vehicle air-conditioning control system to detect total heat load, which can change the vehicle’s air-conditioning capacity mode to maintain the average temperature at 25.2°C∼26.2°C and the average humidity at 46.6%∼54.4% in the cabin. When the inner heat load is stable, the rest times of the compressor can reach 16∼23 times per hour, which attains a rate of fuel saving around 21%∼28%. With the proposed architecture, the purpose of the low-energy-consumption vehicle air-conditioning system can be achieved, which, at the same time, creates a comfortable environment inside the cabin.

Zero Carbon

In order to accommodate the global climate change, the idea of constructing zero-carbon green buildings has become the main stream and highest standard in building design in many countries. Located in subtropical zone, Taiwan features hot and humid weather in summer. The high usage of air conditioning is the main challenge to design zero-carbon green buildings in Taiwan. However, the temperature in the middle and high mountain areas decreases as altitude increases and makes it possible to create a living environment without using air conditioning in the summer. This project analyzed weather data in the middle and high mountain areas of Taiwan. The degree hour method and weather research and forecast model were used to evaluate the demand of air conditioning in the summer based on outside air temperature. The results showed that the low air conditioning load areas are above 1000 m elevation. This project then simulated energy consumption of a two-floor building near the Sun Moon Lake, an area of low air conditioning load, to explore the feasibility of zero-carbon green buildings in Taiwan. Based on the life style of a four-member family, a simulation process was conducted to estimate energy consumption of various appliances and different life habits. This study showed that the energy consumption in the buildings can be reduced up to 70% by using three major design strategies. These strategies include selection of a low air conditioning load location, using high energy efficient appliances, and application of energy conserving habits. Followed by renewable energy evaluation, it is possible to put zero-carbon green building into practice in Taiwan.
