Abstract
Description
Technical Field
[0001] The invention belongs to the field of building energy conservation, and its international IPC classification number is E04H14 / 00 or E04B5 / 16, and in particular relates to a passive low-energy building based on a full-process quality control system. Background Art
[0002] Against the backdrop of global warming and energy shortage, building energy conservation with high energy efficiency and low emissions as the core is playing a vital role in achieving national energy security and sustainable development. Passive low-energy buildings refer to buildings that make full use of the natural environment and resources, and combine various passive energy-saving measures such as natural ventilation, natural lighting, solar radiation, and indoor non-heating heat sources with thermal insulation and heat-insulating energy-saving technologies of the building's exterior envelope. The two notable features of passive low-energy buildings are: first, they significantly improve the comfort of the indoor environment, including indoor thermal comfort (temperature, humidity, air velocity), indoor air quality, indoor noise level, indoor lighting level, etc.; second, they can significantly reduce building energy consumption and achieve more than 90% of building energy-saving goals. Developing and popularizing passive low-energy buildings, while ensuring the comfort of the indoor environment, by significantly reducing the building's heat / cold load, and getting rid of the dependence on active mechanical heating and cooling systems to the greatest extent, thereby reducing the building's heating and cooling energy consumption, while making full use of renewable energy to get rid of the dependence on traditional fossil energy, has become an important means of energy conservation and emission reduction for countries leading international building energy-saving technology.
[0003] The key technologies for passive low-energy building applications include: 1. High-efficiency non-transparent external insulation system: The heat transfer coefficient of the roof, exterior wall, floor or unheated basement top plate is K≤0.15W / (m 2 ·K); 2. Efficient external door and window system: total solar transmittance of glass g≥0.35, glass selectivity coefficient S≥1.25, whole window heat transfer coefficient K≤1.0W / (m 2 ·K), glass heat transfer coefficient K≤0.8W / (m 2 ·K), profile heat transfer coefficient K≤1.3W / (m 2 ·K); 3. Ventilation system with high-efficiency heat recovery device: sensible heat recovery efficiency ≥ 75%, total heat recovery efficiency ≥ 70%, ventilation power demand ≤ 0.45W / (m 3 / h), internal air leakage rate ≤2%, external air leakage rate ≤2%; 4. Good building airtightness measures: the setting technology of the overall airtight layer of the building, the setting technology of the sealing structure of windows and walls, and the setting technology of the sealing structure of various pipe openings; 5. The design concept of no thermal bridge and the construction method of building nodes: the anchoring technology of connecting the insulation material with a thickness of ≥250mm to the load-bearing wall, the connection technology of the balcony and the main structure without thermal bridge, and the treatment technology of the key node structure; 6. High-thickness exterior wall external insulation fire protection technology: the thermal conductivity coefficient of the fireproof material λ≤0.045W / (m·K), no spread, no dripping, and no release of toxic gases in case of fire, the setting technology of horizontal surrounding fire isolation belt or fire isolation belt on three sides of door and window openings; 7. Moisture-proof and waterproof technology; 8. Noise protection measures.
[0004] However, the prior art cannot comprehensively and effectively solve all of the above problems.
[0005] Unlike ordinary buildings, the design, construction and operation of passive low-energy buildings are based on indoor environmental indicators and building energy consumption indicators as constraints, and are implemented using performance-based design methods, refined construction methods and intelligent operation modes to achieve refined design, refined construction and refined operation.
[0006] The quality of passive low-energy building projects involves design quality, material / product quality, equipment quality, construction quality and operation quality. Therefore, for passive low-energy building projects, it is an important guarantee to ensure that the expected goals are achieved by controlling the building's energy efficiency goals (i.e. building energy-saving effects) and comfort goals (i.e. building operation effects) as the core, using the whole process quality control system and implementing the whole process dynamic management.
[0007] In the prior art, CN104597884 A discloses a building energy-saving system, in which a data acquisition module is used to collect raw data information indoors and outdoors, and transmits the information to a data processing terminal through a data transmission module; an environmental acquisition device is arranged in a building to collect environmental parameters in the building; the data transmission module is used to transmit the collected data information, and an energy consumption equipment status acquisition module is connected to the data processing terminal.
[0008] However, the above-mentioned existing technologies only involve a single energy consumption monitoring system, which can monitor the energy consumption of buildings or the indoor environment during the operation stage. It cannot achieve full-process control of the quality level of construction projects from the perspective of planning, design, bidding, construction, testing, acceptance, delivery, and operation. Even if it is only for the operation stage, it cannot achieve comprehensive control from the perspectives of the long-term quality, long-term air tightness, user satisfaction, etc. of the construction projects.
[0009] The energy-saving mechanism of passive low-energy buildings is as follows: reducing the temperature difference and heat transfer between the indoor and outdoor areas of the building through an external envelope structure with excellent thermal insulation performance without thermal bridges; regulating the solar radiation heat gain of the building through Low-E coating technology of external window glass and effective external shading facilities; reducing the ventilation infiltration and heat transfer between the indoor and outdoor areas of the building through good airtightness measures and a fresh air system with high-efficiency heat recovery; and effectively utilizing non-heating heat sources such as indoor personnel, lighting, and equipment to dissipate heat, so that the building can maintain appropriate indoor thermal comfort with extremely low auxiliary heating and cooling loads / energy consumption.
[0010] Among the above energy-saving mechanisms, the external envelope structure with excellent thermal performance, effective external shading facilities and good airtightness measures belong to the building envelope structure energy-saving technology, and the fresh air system with efficient heat recovery function belongs to the equipment energy-saving technology. It can be seen that the high-efficiency operation of passive low-energy buildings is the result of the coordinated work of the building's external envelope structure and ventilation equipment. Under this operating mechanism, the annual heating demand of passive low-energy buildings does not exceed 15kWh / (m 2 a) is one-tenth to one-quarter of that of ordinary energy-saving buildings, and the annual total primary energy demand (including heating, cooling, ventilation, domestic hot water, lighting and primary energy demand of household appliances) does not exceed 120kWh / (m 2 a). On the basis of passive low-energy buildings, further utilizing renewable energy will make it possible to build zero-energy buildings or even energy-generating houses. Summary of the invention

The 50mm thick rock wool belt on the lower side of the basement top plate extends from the basement top plate to the inner side of the basement outer wall, with an extension length of 1m.
[0105] The highly efficient non-transparent external insulation system adopts a 240mm thick second extruded polystyrene board laid on the outside of the main structure wall buried below the soil, with a laying range extending 1m downward from the outdoor floor and 500mm upward from the outdoor floor. The heat transfer coefficient reaches 0.13W / (m 2 K); double-layer insulation material is staggered and pasted, dry density ≥30kg / m 3 , thermal conductivity ≤0.030W / (m·K), combustion performance grade B1.

[0107] The high-performance exterior door and window system adopts aluminum-wood composite profile exterior windows, three-glass two-cavity hollow argon-filled fire-resistant glass, and durable warm edge spacers. The heat transfer coefficient of the exterior window is K≤1.0W / (m 2 ·K), profile heat transfer coefficient K≤1.3W / (m 2 ·K), glass heat transfer coefficient K≤0.8W / (m 2 ·K), the total solar transmittance of the glass is g=0.35, and the glass selectivity coefficient LSG≥1.25.

The fire resistance integrity is not less than 0.50h.
[0108] The design concept of no thermal bridge and the construction method of building nodes are as follows: the external doors and windows should be installed close to the outside of the structural wall, and the joints between the external door and window frames and the structural wall should be sealed with a durable door and window opening sealing system composed of a waterproof vapor barrier membrane, a waterproof vapor permeable membrane and a special adhesive. The waterproof vapor barrier membrane is used on the indoor side, and the waterproof vapor permeable membrane is used on the outdoor side.

The overlap width of the waterproof vapor barrier membrane or the waterproof vapor permeable membrane should not be less than 100mm. The external wall insulation should cover the door and window frames as much as possible, and the width of the exposed part of the door and window frames should be reserved for 15mm. The exterior window sill should be equipped with a durable metal window sill to prevent rain erosion and damage to the insulation layer. The outdoor metal window sill should have a structural connection with the lower opening of the window frame and be embedded 10 to 15 mm into the lower opening of the window frame. A drip line should be provided at the bottom edge of the metal window sill. The joint between the lower side of the metal window sill and the insulation layer of the exterior wall should be sealed with a pre-compression expansion sealing tape. The ends of the metal window sill on both sides should be turned up and embedded 20 to 30 mm into the insulation layer of the exterior wall at the side opening of the window. The joint between the turned-up ends on both sides of the metal window sill and the insulation layer of the exterior wall should be sealed with a pre-compression expansion sealing tape.
[0109] The ventilation and air conditioning integrated system with high-efficiency heat recovery device provides a fresh air volume of 30m per person per hour. 3 The system has the function of adjusting the air volume, which can be adjusted automatically according to the indoor conditions, and can also be adjusted manually. It can start and stop automatically according to the indoor carbon dioxide concentration. The fresh air heat recovery system adopts a full heat recovery movement, with a full heat recovery efficiency of ≥70% and a sensible heat recovery efficiency of ≥75%. The fan power per unit air volume of the heat recovery device is not more than 0.45Wh / m 3. Primary filters that can filter large particles, flying insects, etc. are installed at the outdoor fresh air and exhaust vents. Filters are installed at the fresh air vents and return air vents. The filter grade of the fresh air vent is not less than G4+F8, and the filter grade of the return air vent is not less than G4, and it has a reminder replacement function. The internal air leakage rate of the fresh air system is less than 2%, and the external air leakage rate is less than 2%. The fresh air duct leading to the outdoors is covered with 80mm thick rubber and plastic insulation, and the exhaust duct leading to the outdoors is covered with 60mm thick rubber and plastic insulation, and should be marked on site to distinguish them; the indoor air supply duct is covered with 20mm thick phenolic insulation. The indoor unit and the outdoor unit each have independent condensate risers to collect and discharge the condensate generated by the unit. The condensate pipe uses a 20mm thick rubber and plastic insulation casing.
[0110] The ventilation and air conditioning integrated system with high-efficiency heat recovery device is installed in each apartment. The bedroom, living room and dining room are equipped with air supply outlets, which are connected to the equipment through air supply ducts; each bathroom is equipped with a return air outlet, which is connected to the equipment through a return air duct; the dining room or corridor is equipped with a circulating air outlet, which is connected to the equipment through a circulating air duct; each exterior wall is opened as an air inlet and an air outlet to obtain fresh air from the outside, or to discharge the dirty air after heat recovery to the outside. The air inlet and exhaust ducts are equipped with heat-insulating and sealed electric valves, which are interlocked with the fan to ensure the air tightness of the building. Outdoor fresh air enters the equipment through the air inlet duct, and the fresh air after processing (heat exchange, haze removal, cooling, heating, dehumidification, etc.) is sent to each room through the air supply duct, which is responsible for processing the cold and heat loads of each room and diluting the indoor carbon dioxide, and then overflows to the bathroom through the door gap or air guide groove of the room, enters the heat exchange core of the equipment through the return air outlet of the bathroom, exchanges heat with the outdoor fresh air, and then is discharged to the outside through the exhaust duct. When the indoor cold (heat) load is large, start the circulating air, which can quickly reduce the indoor cold and heat load. When starting the circulating air, it should also include the minimum amount of fresh air required indoors. The indoor main air duct wind speed is 3-4m / s; the branch air duct wind speed is not more than 2m / s; the air outlet wind speed is 1.5-3m / s; the return air outlet wind speed is not more than 4m / s; the outdoor air inlet wind speed is 2-4m / s; the outdoor exhaust outlet wind speed is 3-5m / s; the indoor air flow rate is not more than 0.15m / s.
[0111] The ventilation and air conditioning integrated system with high-efficiency heat recovery device adopts frequency conversion technology for the compressor, and the fresh air fan adopts stepless speed regulation EC fan. The control system supports multiple partitions and multiple indicators (temperature, humidity, carbon dioxide, PM 2.5 ) Independent control. The system performs regional and variable air volume intelligent control according to the real-time indoor cooling and heating loads, fresh air volume requirements, cleanliness, etc. The indoor thermostat and carbon dioxide monitoring point are set in the living room.
[0112] The integrated ventilation and air conditioning system with a high-efficiency heat recovery device operates in the following mode:
[0113] (1) Comfort mode. The indoor environment is controlled to provide comfort with the highest hygiene and health standards. In terms of air source, outdoor fresh air is used as much as possible to meet the needs of indoor cooling and heating and reduce pollutant concentrations. In terms of air flow organization, fresh air first enters the bedroom, then flows to the living room, and finally is discharged from the bathroom to the outdoors. Avoid the use of circulating air as much as possible to minimize cross-contamination caused by wind between bedrooms.
[0114] Under normal working conditions, when the temperature fluctuates within the set range of ±2℃, or PM 2.5 Concentration 50-115 μg / m 3 Floating, or relative humidity greater than 70%, or carbon dioxide concentration greater than 1000PPM, the system only uses fresh air with adjusted temperature (when necessary) to optimize indoor air quality.
[0115] In the following situations that seriously affect comfort and health, the circulating air will be turned on to increase the total air volume in order to quickly improve the indoor air quality: 2.5 The concentration exceeds the national third-level standard of 115 μg / m 3 When the indoor temperature exceeds the set value by ±2°C; when the indoor relative humidity exceeds 80%.
[0116] (2) Energy-saving mode. Minimize energy consumption while meeting basic hygiene and health needs. In terms of air source use, use indoor circulating air as much as possible to meet the needs of indoor cooling and heating and reduce pollutant concentrations. Fresh air is only delivered to the room when the carbon dioxide concentration exceeds the standard or the daily minimum ventilation volume needs to be met. The airflow organization of the circulating air is that the circulating air is taken from the living room, filtered and temperature-adjusted, sent to the bedroom, and then flows back to the living room. In this mode, pollutants in each area will be mixed together and diluted together in the entire apartment, posing a risk of cross-contamination. However, since the circulating air is also filtered, it can meet basic hygiene needs.
[0117] Under normal working conditions, when the temperature fluctuates within the set range of ±2℃, or PM 2.5 When the concentration exceeds the standard, or the relative humidity is greater than 70%, the system uses circulating air as the air source to improve the indoor air quality. Whether to mix fresh air depends on the carbon dioxide concentration. When the indoor temperature exceeds the set value by ±2℃, or the relative humidity is greater than 80%, the unit uses the maximum cooling and heating capacity, that is, fresh air plus circulating air, to quickly adjust the temperature and humidity.
[0118] The energy consumption of the building test samples was tested during the heating and cooling periods, and the test comparison results are as follows:
[0119] Terminal energy consumption analysis
[0120] During the test, the only energy used in the sample rooms (East Room on the second floor, 132m2; West Room on the second floor, 134m2) was electricity. Three electric meters were used to measure the electricity consumption of the air conditioning unit (including heating, cooling and ventilation electricity), lamps (including lighting electricity), and sockets (including household appliances, cooking and domestic hot water electricity). The actual electricity consumption during each test period is shown in Table 1.
[0121] Table 1 Electricity consumption statistics
[0122]
[0123]
[0124] Based on the data from the second heating and cooling periods, the average daily electricity consumption of the air-conditioning fresh air unit during the winter heating period is approximately 13 degrees per day, and the average daily electricity consumption during the summer cooling period is approximately 6 degrees per day.
[0125] Energy cost analysis
[0126] According to the electricity metering results, the electricity costs for heating and cooling (including fresh air) during the entire heating or cooling period are calculated and compared with the heating and cooling energy costs of ordinary residential buildings. The comparison results are shown in Table 2. The electricity fee in the table is calculated at 0.52 yuan / kWh, and the municipal central heating cost of ordinary residential buildings is calculated at 0.24 yuan / m 2 / day, the heating area is calculated as 70% of the building area, and the cooling cost is calculated based on the electricity charge of an air conditioner with a power consumption of 0.8 degrees per hour and turned on for 5 hours a day.
[0127] Table 2 Energy cost analysis
[0128]
[0129] Compared with ordinary residential buildings with centralized heating, the heating cost of passive low-energy buildings can be reduced by 70-80%, and the cooling cost can be reduced by 50-60%. Taking the energy cost of the east room in the second heating and cooling period as an example, the heating and cooling (including fresh air) electricity costs of passive low-energy buildings are 1,007 yuan and 189 yuan respectively, while the corresponding heating and cooling energy costs of ordinary residential buildings are 3,371 yuan and 374 yuan respectively, which are 2,364 yuan and 185 yuan higher than the passive house in a single heating and cooling period.
[0130] According to the average level, passive low-energy buildings save about 0.13 yuan per square meter in heating and cooling costs. 2 / day, 0.02 yuan / m 2 / sky.

[0186] Table 3 Energy efficiency targets for buildings
[0187] Evaluation Project Index requirements <![CDATA[Primary energy demand for heating + cooling, kWh / (m 2 ·a)]]> ≤30 <![CDATA[Total primary energy demand, kWh / (m 2 ·a)]]> ≤120
[0188] As shown in Table 3, the index requirements are applicable to all climate zones in my country. The sum of the primary energy demand for heating and cooling of the building, as well as the total primary energy demand of the building, shall meet the limit requirements at the same time, where the total primary energy demand includes heating, cooling, ventilation, lighting, domestic hot water, auxiliary electricity for equipment and primary energy demand for electrical equipment. The standards are applicable to residential buildings and typical dormitories, hotels, offices and educational buildings. For buildings with other functions, due to differences in internal personnel, lighting, and equipment heat dissipation, the primary energy demand limits for heating and cooling of the building should be adjusted accordingly. A reasonable limit should be that when the technical solution is further optimized, the change in the heating and cooling demand of the building does not exceed 1kWh / (m 2 a) Heating and cooling load changes do not exceed 1W / m 2 , the heating and cooling primary energy demand corresponding to the indoor surface temperature of the exterior wall in winter is not less than 19.5℃. For high energy demand caused by special-purpose lighting and equipment, the total primary energy demand limit of the building can be adjusted accordingly, but high-efficiency equipment should be used.
