5、 Control for Energy-Efficient Buildings The building sector is responsible for about 40% of energy consumption and more than 40% of greenhouse gas emissions; hence the interest in increasing energy efficiency in buildings.Heating,ventilation,and air conditioning (HVAC) is the principal building system of interest,but there are others:lighting,active faade systems,renewable generation sources,and storage.Real-time control and optimization can help building owners and tenants minimize energy consumption and costs based on inputs from occupants,local utilities,and weather conditions.Challenges for implementation of advanced control solutions include the heterogeneity and complexity of typical building environments.New developments in building models and in building automation systems are addressing these and other challenges.

While driving only two places at a time is efficient for continous mining,conventional mining with five unit operations requires driving at least one working place for each operating machine,with a total of 7 to 10 working place desirable for greater efficiency.Because safety conditions override production considerations,as many as 16 working place may be driven in parallel,primarily to provide sufficient ventilation and haulage capabilities.Thus,usually a minimum of five main entries will be driven in opening a drift mine into a coal outcrop,as is shoun in Fig.8.2

Priscilla Ouchida’s “energy-efficient” house turned out to be a horrible dream. When she and her engineer husband married a few years ago, they built a $100,000 three-bedroom home in California. Tightly sealed to prevent air leaks, the house was equipped with small double-paned (双层玻璃的) windows and several other energy-saving features. Problems began as soon as the couple moved in, however. Priscilla’s eyes burned. Her throat was constantly dry. She suffered from headaches and could hardly sleep. It was as though she had suddenly developed a strange illness. Experts finally traced the cause of her illness. The level of formaldehyde (甲醛) gas in her kitchen was twice the maximum allowed by federal standards for chemical workers. The source of the gas? Her new kitchen cabinets and wall-to-wall carpeting. The Ouchidas are victims of indoor air pollution, which is net given sufficient attention partly because of the nation’s drive to save energy. The problem itself isn’t new. “The indoor environment was dirty long before energy conservation came along,” says Moschandreas a pollution scientist at Geomet Technologies in Maryland. “Energy conservation has tended to accentuate the situation in some cases.” The problem appears to be more troublesome in newly constructed homes rather than old ones. Back in the days when energy was cheap, home builders didn’t worry much about unsealed cracks. Because of such leaks, the air in an average home was replaced by fresh outdoor air about once an hour. As a result, the pollutants produced in most households seldom build up to dangerous levels. 1. It can be learned from the passage that the Ouchidas’ house __________ A. is well worth the money spent on its construction B. is almost faultless from the point of energy conservation C. failed to meet energy conservation standards D. was designed and constructed in a scientific way 2. What made the Ouchidas’ new house a horrible dream? A. Lack of fresh air. B. Poor quality of building materials. C. Gas leak in the kitchen. D. The newly painted walls. 3. The underlined word “accentuate” in the third paragraph most probably means ___________. A. control B. worsen C. relieve D. improve 4. This passage is most probably taken from an article entitled “_________”. A. Energy Conservation B. Houses Building Crisis C. Air Pollution Indoors D. Traps in Building Construction
