Using electronic ballasts instead of inductive ballasts and energy-saving lamps instead of incandescent lamps can save up to 70% to 80% of electricity. The lighting effect of an 11-watt energy-saving lamp, with a 60-watt ordinary light bulb, is 80% more energy-efficient than a normal light bulb every minute. For example, the use of 1.2 billion energy-saving lamps throughout the country saves the electricity equivalent to the annual power generation of the Three Gorges Hydropower Station.
Use new air conditioning equipment
In the process of renovation of the office building, replace the old and air-conditioning equipment with a new energy-saving model. If you consider using a heat recovery chiller or a heat pump unit, you can use the recovered waste heat to heat the hot water while providing the air-conditioning. Can greatly improve energy efficiency.
Installation of automatic control device
In areas with low usage rates (such as conference rooms), the presence Sensor is installed to automatically control the switch of the air conditioner.
Optimize the running time and parameters of energy-using equipment
In fact, not every energy-using device is open to work, and it is closed after work. Some devices only use a few hours a day but keep running for 8 hours or even 24 hours. Carefully study the energy equipment (do not let go of even a small light) when it must be used, when it can reduce the load or turn it off.
Use the natural cold air to pre-cool the room at night
In the case where the minimum temperature is low at night, ventilation is performed in advance, and the structure of the building itself is used for cold storage. In addition to reducing energy consumption, this method also maintains good indoor air quality.
Cooling in the transition season
Most commercial office buildings need to be cooled during the transition season due to internal heat sources (eg, people, computers, lighting, etc.), and can use cold outdoor air to meet all or part of the cooling needs, thereby reducing the energy required for system cooling. This cooling method is also called "free air conditioning."
Office computer set appropriate brightness, power saving and eye protection
Adjust the brightness of your computer monitor to an appropriate value. Excessively high display brightness increases power consumption and is not conducive to protecting vision. China currently has 300 million TVs and tens of millions of computer monitors, and this alone can save 5 billion kWh per year.
