1, load category percentage. Electrical equipment is divided into lighting load and power load. They are in different categories of buildings in different percentages of the load, - general lighting and sockets, air conditioning units account for a larger share.
2, office buildings. Including party committees at all levels, government, enterprises, institutions, organizations, community offices, often by the office, meeting rooms. Computer room and supporting rooms (restaurants, garages, etc.).
1) load characteristics: electrical load according to normal working hours, working days for Monday to Friday, working hours are 8:00 a.m. - 5:00 p.m. Air-conditioning load accounted for the total electrical load of 1/4-1/3, the electrical load by the great influence of temperature changes, but the duration of the power time is shorter.
2) in line with the parameters: lighting design should meet the "architectural lighting design standards" GB 50034-2004 on the office building lighting power density value requirements.
3, medical buildings. Including general hospitals, specialty hospitals, rehabilitation centers, emergency centers, nursing homes.
1) building characteristics: general hospitals can be divided into 300, 400, 500, 600, 800 and 1000 beds; according to the hospital level can be divided into three. Two, a hospital. A few days ago often involved - generally for the hospital above the second level. Hospitals are generally divided into outpatient clinics, medical technology, inpatient department, administrative department, logistics department. The layout of general hospitals are decentralized, centralized and semi-centralized. Considering energy saving and convenience of use, the semi-centralized type is mostly used.
2)Load parameters: lighting design should meet the "architectural lighting design standards" GB 50034-2004 on the hospital building lighting power density value requirements.
4, cultural monuments building. Including theaters, cinemas, libraries, museums, archives, cultural centers, exhibition halls, concert halls and so on.
Load characteristics: the electrical load is calculated according to the working time, the working time varies with the service object. Empty withering load accounted for 1/4-1/3 of the total electrical load, greatly affected by changes in temperature, but the duration of electricity is shorter.
5, commercial buildings. Including department stores, supermarkets, food markets, hotels, restaurants, food establishments, bath centers, beauty centers and so on.
1) Load characteristics: electrical load calculated by working hours, with the work called with different service objects and changes. Air-conditioning load accounted for the total electrical load of 1/4 ~ 1 / 3, greatly affected by changes in temperature, but the duration of electricity is shorter. Commercial buildings throughout the lighting should be configured according to the characteristics of the type of business, divided into the store lighting, foyer lighting, window lighting, store lighting and the entire building facade (appearance) lighting, to achieve both differentiated, but also coordinated with each other.
2)Load parameters: lighting design should meet the "Architectural Lighting Design Standards" GB 50034 - 2004 on the commercial building lighting power density value requirements.
6, sports buildings. Including stadiums, gymnasiums, swimming pools, gyms and so on.
1) load characteristics: sports building power load should be differentiated according to the use of the requirements. Only used during the game of large-scale power equipment is appropriate to set up a separate transformer power supply. In determining the number of transformers, should take into account the characteristics of the sports building power load and economic operating conditions, as well as the reliability of the power supply system, it is appropriate to choose more than one small-capacity transformer power supply program. Large sports venues should also reserve a certain amount of spare capacity, as the venue to hold other activities within the temporary power supply.
2)Load parameters: sports buildings playing field illumination standards should be in line with the "architectural lighting design standards" GB 50034 - 2004 regulations.
7, teaching Ken building. Including nurseries, kindergartens, primary and secondary schools. Colleges and universities. Vocational schools, special education schools. Mainly by the classroom (ladder classroom), laboratory, office, reading room and other components.
1) load characteristics: lighting load-based, general classroom lighting using fluorescent lamps, art classrooms should be used with a high transmittance index light source. In order to avoid light curtain reflection and reduce glare, fluorescent lamps long axis should be perpendicular to the blackboard, lighting fixtures from the height of the desktop should not be less than 1.7 m. The blackboard should be set up for special lighting facilities, the average vertical illuminance can not be less than 2001x. other functional rooms see other chapters of the design of the main points.
2) load parameters: lighting design should meet the "architectural lighting design standards" GB 50034 - 2004 on the school building lighting power density value requirements.
