LIGHTING – Lobby
Design Issues: Daylight
Design Ideas: Since the ceiling is so high, I wanted to
choose lighting that would bring it down some to make the lobby more inviting
Warm up the reception area so people will be drawn towards it
Carry in the fixture theme from outside

LOAD REDISTRIBUTION PROCESS:
1) Determined Essential Loads: Gym lighting, receptacles Locker room lighting, receptacles Kitchen Lighting, Receptacles, and Equipment –
Refrigerator, ovens, microwaves HVAC equipment that services these areas
2) Sized a generator and emergency transfer switch based on the calculated loads (taking all demand factors into account)
3) Selected an emergency panel
4) Located generator 25’ from side of building (NEC code)

• The selected equipment will appear here with an explanation of why it was chosen
• A map of the gym in relation to the exits,
locker rooms and kitchen will also be shown

*Analyzed the financial impact of a power factor correction
based off of 12 months worth of utility bills
PROCESS1) PF = cos [tan-1(rKVA Demand/Measured KVA
load)]2) Calculated the PF for all 12 months Medium
General Service Schedule: REACTIVE DEMAND CHARGE = $0.48 per rKVA
3) Reactive billing demand = KW*(kVAR Hours/ kW Hours) – 30
5) Actual cost per month = Reactive billing demand*($0.48 / hour)
CM – PF CORRECTION
![Page 28: Senior Thesis Presentation: The Westlake Recreation Center Summer Padgett Faculty Advisor: Dr. Mistrick Westlake Recreation Center Westlake, Ohio Electrical](https://reader030.vdocuments.site/reader030/viewer/2022020106/56649e915503460f94b966cf/html5/thumbnails/28.jpg)
PROCESS (continued):
6) With the existing and desired power factors use the capacitor correction table to find a multiplier
7) Multiply the building’s electrical 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 (Sprague
Corp.)Total savings for one year = $863.15*Almost an immediate payback!!

Here I plan to show the results of a mechanical
energy analysis when a more efficient glazing is
used on the windows in the lobby
CURRENT GLAZING PROPERTIES:1. Shading Coefficient: 0.812. Visible Light Transmittance: 73 percent3. Visible Light Reflectance: 17 percent4. Summer Value: 0.385. Winter U Value: 0.35

heat load calculations
