(4) The thermal performance limits of exterior windows in cold regions, hot summer and cold winter regions and hot summer and warm winter regions are heat transfer coefficient (W/M 2K) and shading coefficient SC;

(5) Thermal performance limit index without external window control in mild areas; (6) If the limit value of thermal performance cannot be met, the balance judgment of thermal performance of envelope can be adopted. 6. Answer:

(1) Take different window-wall ratios as the basis for determining the thermal performance limit of external windows; (2) The climatic zones in China include cold zone, cold zone, hot summer and cold winter zone, hot summer and warm winter zone and mild zone.

(3) The index of thermal performance limit of external windows in severe cold area is heat transfer coefficient (W/M 2K);

(4) The thermal performance limits of exterior windows in cold regions, hot summer and cold winter regions and hot summer and warm winter regions are heat transfer coefficient (W/M 2K) and shading coefficient SC;

(5) Thermal performance limit index without external window control in mild areas; (6) When shading from the outside, shading coefficient = glass shading coefficient × external shading coefficient; Without external shading, shading coefficient = shading coefficient of glass 7. Answer:

(1) circulation of main pipe and riser to reduce cold water loss; (2) avoiding the leakage of the pipe network and improving the transportation efficiency of the pipe network; (3) Limit the outlet pressure of water supply system, and use water appliances to save water.

(4) Use water-saving appliances such as water-saving showers and faucets to save water. (5) Make a water plan to reduce the energy consumption of hot water transportation. 8. Answer:

(1) direct utilization, roof rainwater quality treatment can choose the following processes according to the raw water quality; A. Rainwater → (initial flow abandonment) → landscape water body; B rainwater → initial flow abandonment → rainwater storage and precipitation → rainwater cleaning.

Pool → plant watering and ground washing; c.

Rainwater → initial flow abandonment → rainwater storage and precipitation → filtration → disinfection → rainwater cleaning pool → toilet flushing, car washing and leisure waterscape; d.

When rainwater is used to make up water for cooling towers or users have higher requirements for water quality, corresponding advanced treatment measures should be added. (2) After proper treatment, the rainwater will be reinjected into the groundwater layer through indirect utilization, or the runoff will be purified through soil infiltration to conserve groundwater.

9. Answer: Dew condensation refers to the phenomenon that the partial pressure of water vapor somewhere inside the envelope is greater than the saturated partial pressure of water vapor at this temperature, which leads to the solidification of water from gas to liquid. Control method: 1. The enclosure structure is arranged on the steam path, which is "difficult to enter and easy to exit"; 2. Set the steam barrier 3. Ventilation interlayer and steam discharge channel.

10, Answer: Curtains are arranged on the inner side of the window to block direct sunlight and often block scattered light, which affects indoor natural lighting. The inner curtains have little effect on reducing the air conditioning load caused by direct sunlight entering the room. An adjustable sunshade device is arranged outside the window, which can adjust the position of the sunshade device as needed, prevent the strong sunlight from entering the room directly through the window glass in summer, effectively reduce the heat gain of the building due to solar radiation and outdoor air temperature through the building envelope and windows, and play an important role in improving indoor thermal comfort in summer.

The reason why the external sunshade is adjustable is because the residents' demand for sunlight entering the room through windows in winter and summer is completely opposite, no matter from the physiological or psychological point of view, and the fixed external sunshade (such as the sunshade on the upper edge of the window) can not well adapt to this opposite demand.

1 1. Answer: Enterprise 201200 * 0.7143+2300 * 4.04+80 *1.4714 = 65438.

Energy consumption per 10,000 yuan output value of this enterprise: 10267 tons of standard coal/250 million yuan = 0.4 1 ton of standard coal/10,000 yuan 12. Answer:

① Energy consumption of urban buildings in northern China ② Energy consumption of rural buildings ③ Energy consumption of urban houses and general public buildings ④ Energy consumption of large public buildings.

13, Answer: The prefabricated concrete structure is a concrete structure formed by assembly, connection and local cast-in-place with precast concrete members as the main components. Housing units or components are manufactured according to the unified and standard specifications of building components, and then transported to the construction site for on-site assembly to produce houses and public buildings.

The characteristics of the prefabricated concrete structure are: (1) various light partition walls can be made to divide the indoor space, and the room layout can be flexible.

(2) The construction is convenient, and the formwork and cast-in-place concrete work are less, which is beneficial to environmental protection and reduces noise pollution and waste of materials and energy.

(3) The construction speed is fast, which has little influence on the surrounding work and life; The building size conforms to the modulus, the building components are relatively standard, the adaptability is strong and the technical and economic benefits are good.

(4) The assembled structure has short cycle, quick capital recovery, reduced overall cost and obvious economic benefits.

(5) In prefabricated buildings, components manufactured by component factories are transported to the construction site by special component trucks for mechanical installation, which can give full play to mechanical efficiency.

(6) Assembled buildings can make full use of industrial waste and save fertile land and other materials in design and production.

(7) Fully automatic production and modern control can be realized during the construction of prefabricated buildings, which promotes the industrial production of the construction industry to a certain extent.

14, answer: (1) Good persistence. Wood is a renewable building material, and the choice of wood structure can reduce the consumption of energy and resources. (2) Save energy. The honeycomb structure of wood makes it 400 times better than steel.

Because of its good thermal insulation performance, wood frame structure can easily reach the high standard of thermal insulation.

(3) Excellent seismic performance. Wood has the best earthquake resistance, and the wood structure shows excellent stability and structural integrity under various extreme conditions.

(4) Good sound insulation performance. The low density and porous structure of wood, as well as the sound insulation wall and floor system, make the wood structure also suitable for buildings with sound insulation requirements, creating a quiet living and working space.

(5) In addition, due to the low ignition point of wood and poor fire resistance of wood structure, it is difficult to meet the larger and more complex space requirements.
