What are the lighting standards that would be appropriate for space? Show your work.

Activity	Illumination (LUX)
Public areas with dark surroundings	20-50
For short visits simple orientation	50-100
Working areas	100-150
Warehouse, homes, theaters, etc.	150
Classes, easy office work	250
Routine office work, PC work, Library study	500

 

a.       The LUX factor must be considered while designing the bulb. As according to the requirement the workstation is 40 inch by 40 inches thus for caring out the details work that 25-watt lamp unable to give luminous. The detailed work carried out with the LUX range is among 300-500 as well as for that type of bulb it lies on the D category. For routine activities, it was familiar with light levels range 100-300 Lux. But now depending on activity it is in the range of 500-1000 lux [1].

b.      As we consider the case two now the spacious room is about 40 inch into 20 inches into 10 inches high as well as four fluorescent bulbs are used, it is 4 inches long as well as for eight hours it is used. The standard lightning range of lux is among 150-300 lux four-inch tube lights. There are lamps amide every two chairs this is for the critical visual task. The category of the bulb is D, and the standards are around 300-500 lux.

c.       For the 60 by 60 inch the last location the ceiling of the shop is 15 inch the range of lux is required among 500-1000 lux for that case, as well as the bulb, is 100 watts. In this case the category of bulb E.

·         What bulbs and fixtures could or would help meet this standard

a.       In the open area the first location, where the LED bulbs should be used in the lamps for that place the Lux is equally required. Canopy is used for the fixture because this fitting is cheaper for that area as well as also energy efficient.

b.       The given next place is meeting place fluorescent bulb are used in that place as well as they are following the fitting which includes the fixture of the ceiling because the height is approximately equal to ten inches.

c.       The last location that is given is for the shops.  For the fixture LED, bulbs are used in the blubs, to meet the standards the ceiling fixture is used that might  help.

·         What savings in energy and cost could be realized assume 1kwh cost 0.10 dollars. The answer should be a simple dollar per year calculations.

a.       The bulb used for 8 hours for the first location:

Usage = 8 hours

1 Kwh cost 0.10$

Dollar per year calculation= (wattage*per day usage)/1000 for the year multiply the 365 days [2].

b.       

  Bulb= 4

Usage = 8 hours

1 Kwh cost 0.10$

Dollar per year calculation= (wattage*per day usage)/1000 for the year multiply the 365 days.

c.       Bulb= 2= each bulb has 100 watt

Usage = 24hours

1 Kwh cost 0.10$

Dollar per year calculation= (wattage*per day usage)/1000 for the year multiply the 365 days.

·         Any rebates available through consumers’ energy?

a.       For the first place LED bulbs are used as it is in the open area there are rebates available

b.      Rebates are also present in the meeting place, in the whole day they only used for eight hours

c.       For the entire day and night the bulbs are used so there are no rebates.
