Building electricity?Design expert support

A few days ago, the Chengdu Housing and Construction Bureau introduced a series of policy measures around promoting the development of green buildings in Chengdu. The continuous and high temperature in recent times has also made everyone pay more attention to saving electricity.

So, what are the power -saving methods in architectural design?

Experts from Chengdu Architectural Design and Research Institute under the Chengdu Design Consulting Group conducted tips.

"In electrical design, we generally take the following energy saving measures: the energy efficiency level of electric transformers, motors, AC contactors and lighting products is selected than the requirements of energy efficiency levels of energy efficiency or energy efficiency levels." He said.

In terms of power supply and distribution system, the substation is located in the center of the load. The electrical well is close to the position of the distribution place, which can reduce the radius of power supply and reduce line loss. Reasonably determine the capacity of the transformer, and choose a energy -saving transformer with low loss, efficient, low noise. The air load loss and load loss of the power distribution transformer meet the value -saving evaluation value stipulated by the current national standards. In addition, energy -saving products should be selected for power distribution and control components.

Through lighting measures, energy saving can also be achieved. For example, if natural light is fully and reasonable, when there is an outer window, the decoration of the lighting furnishings corresponds to reasonably group control according to the window area and other regions. Group control is used to organize organic lighting with indoor artificial lighting to save artificial lighting power.

Indexing, uniform glare value, and color rendering indexes such as the "Standards for Building Lighting" GB 50034 related regulations, and the lighting power density value (LPD) is not greater than the requirements in the "General Specifications for Building Energy Conservation and Renewable Energy".

Select T5 triple -color fluorescent light sources, configure high -quality low harmonic electronics flowers, or compact energy -saving light sources and high -efficiency LED lamps to achieve energy saving.

Set up intelligent lighting control systems to optimize and control public areas, underground garages, and outdoor landscape lighting in the building to achieve energy -saving control of lighting electricity.

Single -phase lighting load is evenly balanced as possible to the three -phase load as possible to reduce the luminous efficiency of voltage loss affecting the light source.

In terms of energy consumption metering and management, the power monitoring and metering system is set up, and electrical energy monitoring and measurement is performed according to the subtraction of the socket, outdoor lighting, air conditioning, pump pumps, and special power consumption. In addition, the building self -control system (BAS) can be adopted to centrally monitor, control and manage mechanical and electrical equipment to improve equipment use efficiency, energy conservation, and extend the life of the equipment.
