Building Demographics
This is a two family brownstone which the bottom floor is occupied by a day care during the day time from 9am to 4pm. The total size of the house is 2500 sq ft
and has 10 rooms. There were some renovations made to this house a couple of years after this floor plan was made. There now is a added bedroom on the first
floor and a small kitchen on the second floor. The top floor is occupied by 3 member family.
Backgroundnotes
My company was called by the owner of the audited house because he believed his utility companies might have been over charging him on his monthly bills. He
also wants to improve the greeness of his property and become more energy efficient.
Plan
My plan is to visit the owner’s residents; inventory and energy audit his entire home. When I create an estimate of the energy use annually in is home I will the
compare it to his actual utility energy charges annually.
Objective
Energy Audit the Owners home in order to give some suggestions on the best energy efficiency practices for residential homes.

Notes to consumer:
Your energy estimate was almost equal to your actual energy utilities bill minus utility taxes. There were no signs of foul play from your utility provider.
Suggestions:
To receive maximum efficiency on your energy use:
1. Search for utility companies with the best supply and delivery rates.
2. Shop for appliances and equipment with the energy star standard.
3. Make sure airconditioners and heaters have clean filters.
4. Switch lights of when not in use, buy energy efficient light bulbs instead of incandescents.
5. Unplug and turn of electricity requiring electronics and appliances when not in use.
6. Utilized natural sun light if applicable.
7. Upgrade Air conditioner units of 8,000 BTU’s/ 12,000 Watts/hr, on the 1st floor and two 8,000 BTU’s/ 7,000 Watts/hr on 2nd floor. Purchase updated energy
saving Kenmore Energy efficient AC with human body heat sensor. This version supplies 12,000 BTU’s and requires 5,000 Watts/hr to operate. See Excel Spread
sheet for data analysis.
