看看老美关于应急照明部分

Under the 2008 standard, most buildings had a lighting allowance of 0.3 WSF for security and egress purposes at all times. The 2013 standard has a maximum security and egress lighting allowance of 0.2 WSF during normal business hours in a building (this lighting may remain energized even if the space is unoccupied during normal business hours). However, general and egress lighting must be shut off when unoccupied after regular business hours. To meet fire codes, the egress lighting must be responsive to occupants (it must turn ON automatically after hours), and the controls have to fail into a functioning state. As an exception, offices are allowed up to 0.05 WSF, for lighting during unoccupied periods, but only along emergency egress areas designated on the building plans.
Note that an egress lighting system provides enough illumination for occupants to safely leave a space under normal building operating circumstances. Emergency lighting provides a minimal amount of light for egress when the normal lighting system has failed.
This change in egress lighting doesn’t affect emergency lighting system requirements, but it does impact the way emergency lighting initiates the operation of battery packs and charges the batteries. A generator and transfer switch emergency lighting system may also have design impacts to consider.
哪个大师可以翻译下？ 。。。。0.5W per sq ft (WSF) 。。。。 安全法规和出口照明关闭都发生了巨大变化在这个新版本的标准。根据2008年标准,大多数建筑的照明津贴0.3 WSF安全与出口的目的。2013标准最大安全性和出口照明津贴0.2 WSF在正常营业时间在建筑照明(这可能仍然精力充沛,即使空间无人在正常营业时间)。然而,一般出口照明时必须关闭正常营业时间后无人居住。满足消防法规,出口照明必须适应居住者(一定时间后自动打开),和控制失败一个运作正常的国家;作为例外,办公室允许0.05 WSF、照明在空闲的时间,但是只有在紧急出口地区指定的建筑计划。
注意,乘客的疏散照明系统提供足够的照明安全正常的建设运营情况下留下一个空间。应急照明为出口提供了少量的光,当正常照明系统已经失败了。
这个出口照明的变化不影响应急照明系统需求,但它确实影响应急照明的方式启动电池的操作和收费的电池。发电机和转换开关紧急照明系统也可能设计要考虑的影响。 自动翻译的，不够正确
