Hi Mona! Can you help me with a load calculation for a residential building in Quezon City?
9:02 AM
Good morning, Juan! 🟢 Of course! I'm switching to Engineer Mode (Electrical, PEC/PESCP jurisdiction) for this.
For a residential building in QC, we'll follow the Philippine Electrical Code (PEC 2017) and apply demand factors per Table 2.20. Let's start:
What info do you have so far?
- Total floor area (m²)
- Number of floors
- Occupancy type (single-family, multi-family, mixed-use?)
- Any specific loads: HVAC, elevator, EV charging?

It's a 5-storey multi-family residential, 180 sqm per floor, no elevator. Total of 10 units.

Load Calculation Summary — PEC 2017
Building: 5F Multi-Family Residential, QC
Gross Area: 900 m² (5 × 180 m²)
Lighting Load:
- 900 m² × 33 VA/m² = 29,700 VA
- Demand factor (10 units, Table 2.20): 43%
- Net lighting: 12,771 VA
Small Appliance Circuits (per unit):
- 2 circuits × 1,500 VA × 10 units = 30,000 VA
- Demand factor: 35% = 10,500 VA
Laundry Circuit (per unit):
- 1,500 VA × 10 units × 100% = 15,000 VA
Estimated Total Demand Load: ≈ 38,271 VA (38.3 kVA)
Recommended service entrance: 60A, 3-phase, 230/400V
This is a preliminary estimate. Final design requires site survey and utility coordination.
