Standard is the leader and guardian of building lighting energy saving

2015 is the full implementation of the "standard" architectural lighting design GB50034-2013 a year, especially the lighting power density value of LPD plays a crucial role in the construction of energy-efficient lighting, have more strict requirements in the standard. Table 1 residential building LPD value changes, compared with the 2004 version of the version of the 2013, the level of illumination has not changed, but the current value of LPD and target values were reduced by 14% and 17%, residential building lighting energy saving is very significant.

Table 2 is the office building site LPD value variation, compared to two editions, illuminance levels remain the same, but the LPD of the current value and the target value changes, according to different places, the current value of 15%~18% reduced, the target value decreased to about 10%, office building energy-saving lighting is also very obvious.

Table 3 is the commercial building part places the changes of LPD values, similar to the old two version of the standard illuminance values remain unchanged, but LPD has changed greatly. According to different places, the current value is reduced by more than 15%, the target value is reduced by nearly 10%, store building lighting energy saving is also very obvious.

Table 4 is the hotel building part places the changes of LPD values, the two version of the standard illuminance value remained unchanged (lobby, foyer, except) but LPD has great changes. According to different places, the current value and target value of up to 53%, mainly because the hotel can be a large number of LED lights, lighting energy saving is very obvious.

Sports lighting will need to meet the relevant requirements of "standard" electric sports building design JGJ354-2014, section 19.3.1 of the code, site lighting unit of illumination power density B and above grade sports building value should be consistent with the requirements in table 5.

Table 5 suitable for television lighting, illuminance table corresponding to the main camera field lighting direction, area is the largest sports venue PA value. Unit lighting power density can be used to control the excessive use of lighting fixtures, to avoid unnecessary investment, energy saving.

The two part is the standard of building lighting overall energy efficiency requirements, no matter what the technology, what products, what kind of system must meet this requirement. Therefore, the standard is the leader in building lighting energy saving, but also the patron saint of building lighting energy efficiency.
