Buildings lighting systems

Key technologies that are used in modern lighting include electronic ballasts, more efficient tubular fluorescent lamps, compact fluorescent lamps, and lighting controls. Fluorescent lighting is the predominant lighting system installed in post-1980 buildings and is used in 71 percent of floor space. Specialty retail stores use a combination of fluorescent and... 

The flip side of consumer bias is that some people argue that only fluorescent lamps should be used in buildings. This attitude, while well iiitentioued, is based on an unsophisticated knowledge of the performance of lighting systems. As previously discussed, the efficacy of a lighting system cannot be characterized by lamp efficacy alone. For example, although a fluorescent lamp and ballast may produce... 

A quantified value for stray light within a turbidimeter is difficult to determine. One method uses a standard addition to a formazin suspension of a known low turbidity. But some instruments have a build-in system to determine the stray light and to correct the turbidity reading accordingly (i.e. Instrument C).

To effectively decrease the amount of pollutants resulting from the consumption of electricity in the building, the most effective method of pollution prevention, i.e., source reduction, is to be implemented. An effective guideline for properly retrofitting a new lighting system is to keep the watts per square foot to a maximum of 1.5.

Furthermore, when considering the building construction phase, light systems could perform with lower impacts due to the minor energy needs both for material transportation and installation. 

The electrical contracting industry provides lighting and power installations so that buildings and systems may be illuminated to an appropriate level, heated to a comfortable level and have the power circuits to drive electrical and electronic equipment. Emergency lighting and security systems are installed so that buildings are safe in imforeseen and adverse situations. 

Lighting Visibility is important in exiting a fire. Not only can smoke build up rapidly and obscure vision, but there may be a power interruption to building interiors. Loss of normal fighting is particularly a problem for buildings with few or no windows. The code specifies details for emergency lighting systems, which require routine maintenance to ensure they work when needed. 

The nickel-cadmium battery is also used in power-generating stations and power distribution networks where power supplies must not break down. The batteries are used in switch-gear applications and for control and monitoring functions. In centralized emergency lighting systems in hospitals, public buildings, sports arenas, and schools, nickel-cadmium batteries are often specified in building codes and by consultants in many industrialized countries. 

Once a system has been installed it is necessary to ensure that its continued operation is effectively monitored. Those who find themselves responsible for the means of escape within buildings will need to ensure that the emergency escape lighting system ...
