2 Air Infiltration Current Air Leakage 2,852 Current Air Changes Per Hour 0.91 Recommended Air Changes Per Hour 0.35 Percent of Heating and Cooling Energy Lost Through Air Leakage Potential Savings 5 19 CFM50 Reducing air leakage in your home can decrease your heating and cooling bills Enhance room comfort by reducing drafts 14" HOLE If all the holes in your home were in one spot, it would be like having a 14 inch hole in the side of your house Improve health and air quality by reducing air pollutants, particulates, and pest access Blower Door Test A blower door measures the rate at which air leaks through your home and consists of three parts: (1) a calibrated fan to depressurize the house, (2) an adjustable frame and jacket to close off the door, and (3) a pressure gauge. The blower door depressurizes your home to a standard test pressure (50 Pascals) and a digital meter reads how much air flows through the fan at that pressure. Using this data we quantify how much air leaks out of the building in cubic feet per minute (CFM), at ambient temperatures and pressures over the course of a year. Seal the holes from above in your attic, and below in your crawlspace and/or basement. We dramatically reduce the amount of air leaking in and out of your home, with no visual impact.

3 Insulation Insulation Ratings Your Home Ceiling R31 R38 Walls R0 R13 Floor R0 R19 Recommended Values 54 Potential Savings 35 Percent of your heating and cooling energy lost through poor insulation By insulating your house to current building standards, you can significantly reduce your heating and cooling bills Proper insulation keeps you warmer in the winter and cooler in the summer Your Ceiling Insulation Your Floor Insulation Recommended Ceiling Insulation Today s insulation materials are less likely to have harmful chemicals such as formaldehyde Thermal insulators are materials specificially designed to reduce heat flow by reducing conduction and radiation. Insulation s ability to inhibit the heat flow through a building assembly is measured as an R-value, or resistance to heat flow. The greater the R- value, the better insulation performs. We can add insulation to areas of your home that are under-insulated.

4 Windows Current Windows Double Pane, Wood or vinyl Frame, Clear Glass Percent of Heating and Cooling Energy Lost Through Your Windows 12 Potential Savings 2 Reduce your heating and cooling bills by replacing your windows with double paned, low-e windows Reduce outside noise and drafts High performance windows add style and value to your home Your Windows Floor to Ceiling Windows Operable Windows The National Fenestration Rating Council (NFRC) grades windows on the following attributes: U-Factor measures how well a window prevents heat from escaping a home Solar Heat Gain Coefficient (SHGC) measures heat blocked from sun Visible Transmittance (VT) measures how much visible light comes through window Air Leakage (AL) measures outside air that comes into a home Condensation Resistance (CR) measures how well window resists condensation We can recommend replacement windows in your house with double pane, low-emissivity (low-e) windows. We also recommend that all replaced windows are properly weatherproofed and air sealed.

5 Heating Current Furnace Size 66,000 Required Furnace Size 43,886 Current Operating Efficiency 95 Recommended Operating Efficiency 95 Potential Savings 0 BTU BTU Save on your heating bill by installing a properly sized, high efficiency furnace Improve comfort with a furnace that quickly and efficiently heats your home 1.5 HOMES Your existing furnace is 2 years old, 50 oversized and has the potential to heat 1.5 homes Reduce the risk of carbon monoxide poisoning and fires with a high efficiency, closed combustion furnace Your Heating System A correctly sized heating system is designed to provide heat at the same rate that air cools or escapes to the outdoors. Properly sizing a heating system is important for a number of reasons, including the overall efficiency of the system and maintaining a comfortable temperature in your house. A heating system that is oversized operates at lower efficiency and short-cycles, meaning it turns on and off more frequently than necessary. This results in higher cost, overheated air and increased wear on your furnace. Most furnaces are expected to operate for 18 years. We can replace your existing furnace with a high efficiency unit. Your new unit will produce heat more efficiently, and the blower that delivers air will be more efficient.

6 Cooling Current AC Size 3.0 Recommended AC Size 3.0 Current Operating Efficiency 13 Recommended Operating Efficiency 16 Potential Savings NA TON TON SEER SEER 1 HOME Your existing AC is 2 years old, 0 oversized and has the potential to cool 1 home Reduce cooling bills by installing a properly sized, high efficiency air conditioning unit Keep your home cool with a properly sized air conditioner Keep air clean and reduce allergens with a better air filter New AC technology uses environmentally friendly refrigerants without CFC Your AC Outdoor Condenser High Efficiency AC Unit The efficiency of air conditioners is often rated by the Seasonal Energy Efficiency Ratio, or the SEER value. The SEER rating of a unit is the cooling output in BTUs during a typical cooling-season divided by the total electric energy input in watt-hours during the same period. The higher the unit s SEER rating, the more energy efficient it is. There have been significant advances in refrigerant and compressor design in the last few years, enabling much more efficient AC systems. Most air conditioners are expected to operate for 15 years We can replace your existing air conditioning unit with a high efficiency unit that keeps your home cooler for less money.

7 Duct Leakage Current Duct Leakage Current Leakage Percentage 13 Potential Savings 7 CFM25 Percent of your heating and cooling energy wasted by your duct system Save 7 on your heating and cooling bills if we can reduce duct leakage to 5 Reduce room by room temperature differences. Make rooms warmer in the winter and cooler in the summer Your Ducts Sealed Duct Duct Blaster Test Prevent dust and mold being sucked into your home from your crawlspace, garage or attic The duct blaster is a diagnostic tool used to measure air leakage through a ducted system. After sealing all the heating and cooling vents, the duct blaster fan pressurizes the duct system to a designated test pressure (25 Pascals) that mimics the operating pressure when the furnace or air conditioning is on. The fan measures the amount of air leaking through the ducts and we can convert that to a percentage based on the size of your system. Seal and/or replace or insulate your existing duct system to address the leakage, temperature loss and sizing issues that cause room-by-room variations in temperature.

8 Water Heating Current Capacity Current Age 1 GPM YEAR Current Energy Factor 0.93 Recommended Energy Factor 0.91 $ 0 Save $0/year by upgrading to a high efficiency water heater Save by upgrading your water heater to a unit that has an EF of 0.91 and thermal efficiency of 0 Reduce the risk of running out of hot water Eliminate standby loss and improve safety with a high efficiency tankless unit Your Water Heater Clean Out Kit High Efficiency Tankless Energy Factor (EF) is a measurement of how efficiently a water heater produces and stores hot water. EF is a function of recovery rate (how efficiently heat is transferred to water), standby losses (associated with the insulation around the water heater) and cycling losses (the loss of heat as water circulates in and around the tank). The higher the EF the more energy efficient the water heater. Most water heaters are expected to operate for 10 years. We can replace your existing water heater with a new high efficiency tankless unit

9 Appliances Appliance Type Make Model kwh / Year $/Year Potential Savings/Year Refrigerator 1 sub zero BI-36u/S/TH 579 $74 $26 Dishwasher 1 Miele G2872scvi 134 $17 $5 Clothes washer 1 maytag FAV $17 $10 Clothes dryer 1 Maytag MDE6800AYW 485 $62 $0 Of all the appliances in your home, washers, dryers and refrigerators use the majority of the total appliance bill (nearly 90). As a rule of thumb, major appliances more than 10 years old consume more than twice the amount of energy that current Energy Star appliances use. Our savings calculations are based on Dept. of Energy studies for appliance energy consumption, annual savings potential and what you can expect to save by replacing existing appliances with current energy saving models. Replace your existing appliances with current EnergyStar models.
