LIGHTING – Exterior

IES CRITERIA:

• Facial Modeling, peripheral detection, and shadows are issues that must be addressed in this area. The building is open until 10:00 p.m. at night, so security is a concern.

• A horizontal illuminance of 5 footcandles and a vertical illuminance of 3 footcandles is required near the entrance.

• Since I am dealing with the exterior, light pollution is always an issue.

LIGHTING – Exterior

DESIGN GOALS:

• Metaphorically, I want the front porch to act as a beacon, or guiding light to the entrance of the Recreation Center

• Distinct separation between the road and the sidewalk

• Wanted to create a streetscape theme to define pathways and draw attention to the front façade to highlight the architecture

EQUIPMENT USED:

• Davit Mounted 16’ Pole Fixtures Lining the Drive-Around

• Bollards Lining the walkways

• Two metal halide pendant-mounted fixtures in the porch

• Inground wallwashing fixtures to accent the façade

CONCLUSIONS:

• The power density for an entrance with a canopy is 3W/ ft2, so 0.4 W/ ft2 is significantly under this requirement.

• The allowable power density for façade area is 0.25 W/ ft2 , so the power density for my façade just meets this.

• The average porch illuminance is 8.83 fc, which is more than the required 5 footcandles.

• Pole fixtures provide distinction between the road and the sidewalk.

• Pendants in porch area give the area a glow without adding light pollution.

Key Plan

LIGHTING – Community Room

IES CRITERIA:

• Very Important: Appearance of the space and color appearance/contrast are issues here because this is an elegant area. Color correlated temperatures should be kept around 3000K.

• Important: Modeling of faces is important in this area since people will most likely be dressed nicely and their facial modeling should reflect this.

• Important: Light distribution on surfaces should be even, there should be no glare and there should be no distracting shadows.

LIGHTING – Community Room

DESIGN GOALS:

• Metaphorically, the community room is like the gem of the recreation center. It is the most formal of all of the spaces and I wanted to reflect that in my design.

• This area is used for banquets, luncheons and dinners most often, so I wanted to design it as a dining area with adequate light for note-taking, since there is a speaker every now and then.

• I wanted the room to look like a theatre-type setting with a simple elegance to it for fine dining. I wanted to keep it as uncluttered as possible.

EQUIPMENT USED:

CONCLUSIONS:

•The power density for a cafeteria is 1.8 W/ ft2 and the power density for family dining is 1.9 W/ ft2 , so 1.4 W/ ft2 falls below both of these and is therefore okay.

•Pendants and wall sconces add an air of elegance, while still maintaining a non-cluttered look

• The cove is does not look ‘washed out’ since only one-lamp strip fixtures are used

Power Factor Correction AnalysisPROCESS:

Many utilities charge a penalty for low powerfactors. The power factor is the ratio of workingto total power – the reactive componentperforms no useful work.

* Analyzed the financial impact of improving the power factor to 90% by adding capacitors

* Based off of12 months worth of utility bills supplied by the city’s engineer

Power Factor Correction AnalysisPROCESS:

1) Calculated the PF for all 12 months using the formula:

PF = cos [tan-1(rKVA Demand/Measured KVA load)]

2) Checked the reactive billing demand:Reactive billing demand = KW*(kVAR

Hours/ kW Hours) – 30

3) Calculated the kVAR cost per month based on a Medium General Service Schedule:

REACTIVE DEMAND CHARGE = $0.48 per rKVAActual cost per month = Reactive billing demand*($0.48 / hour)

Power Factor Correction AnalysisPROCESS:

4) With the existing and desired power factors use the capacitor correction table to find a multiplier

5) Multiply the building’s electrical kW load by this number to get the KVAR of capacitors required

RESULTS:Total KVAR cost for 2002: $1691.15100 KVAR of capacitors needed to correct PFCost of 100 KVAR capacitor = $828 (comSprague)

Total savings for one year = $863.15*Almost an immediate payback!!

Exterior Controls

I selected an outdoor controller to control the exterior lighting loads (Poles, Inground fixtures, bollards). The Outdoor Controller uses the exterior photocell sensor to read light levels and transmit the data to the controller module. The photocell will be mounted on the porch roof, which faces the northern sky.
