Your utility provider(s): Home Energy Assessment Your Energy Smart Analyst: Charles Cady (970) 379-2961 Woodruff Residence 312 West Hyman, Aspen, CO 81611 Pitkin jeffrey@cloudhilldesign.com (970) 452-9008 Building type: Single Family Year built: 1956 Square footage: 1,536 Primary heating fuel: Natural Gas Number of bedrooms: 3 Number of occupants: 2 Welcome to Energy Smart! Chalet style home in Aspens west end. The owner is planning a renovation with efficiency upgrades in mind. Currently in the planning stage. The assessment was completed as a beginning baseline. Air sealing would be a huge improvement. Assessment overview: Energy Usage Your Energy Smart Analyst: Charles Cady (970) 379-2961 Electric utility provider: City of Aspen Electric Electric account #: 012503656000 Electricity cost per kWh: $0.11 Annual electric usage: 0 kWh Annual electric cost: $0 Gas utility provider: Black Hills Energy Gas account #: 3604100130 Gas cost per Therm: $0.85 Annual gas usage: 0 Therms Annual gas cost: $0 Woodruff Residence 312 West Hyman, Aspen, CO 81611 Pitkin jeffrey@cloudhilldesign.com (970) 452-9008 2 Recommended Upgrades Your Energy Smart Analyst: Charles Cady (970) 379-2961 When your Analyst performed your Home Energy Assessment, information was collected to estimate annual energy savings on projects you might consider completing to save money on your energy bills. Below is a breakdown of those suggested improvements, the estimated costs and potential annual savings, which were calculated through software modeling. A Savings to Investment Ratio (SIR) of 1 or greater means that the resulting energy savings will pay for the cost of the project. Energy Detail (estimated)Existing Home Improved Home Units Annual energy consumption MMBTU Annual electrical consumption kWh Annual gas consumption THERMS Potential PV system size to offset annual electric usage (estimated)KW Recommended Improvement Estimated Cost Estimated Annual Savings SIR Increase wall insulation to save energy and increase comfort.$0 $84 Replace incandescent lights with CFLs or LEDs to save energy and replacement costs.$5 $5 6.4 Increase attic insulation and coverage to save energy and increase comfort.$1,206 $59 1.0 Insulate your slab to save energy and increase comfort.$2,895 $51 0.4 Add storm windows or install new windows to save energy and increase comfort.$5,571 $89 0.3 114.3 4,001 1,007 2.9 77.3 3,928 639 2.8 3 Cubic volume: 11,520CF Blower door flow rate: 2,972CFM50 0 0.2 0.4 0.6 0.8 1 1.2 Your Home Average Home Tight Home Leaky Home Natural Air Changes per Hour (ACHn) Air Leakage Energy Smart Tip: Your analyst used a blower door fan to test for air leakage. This test helps determine how leaky or tight the home is relative to other homes. Your home’s natural leakage rate is shown in the chart on the left. A very leaky home costs more to heat, while a very tight home may require continuous mechanical ventilation. Leaks can be repaired through attic floor sealing, caulking, weather stripping, and other means. Your Energy Smart Analyst: Charles Cady (970) 379-2961 CF = Cubic Feet. The volume of air contained in a 1’ x 1’ x 1’ cube. CFM50 = Cubic Feet per Minute at 50 Pascals negative pressure. This number estimates how much air your home loses each hour. ACHn = Natural Air Changes per Hour. Expressed in the chart above as 1.05, this means that about 105.00 % of the air in your home is lost to the outside every hour. Infiltration at the upper level door.Infiltration at the sill plate .Blower door set up for the pressure test. Recommendations: Air infiltration observed at exterior doors, attic access, windows and trim, switches, outlets and sill plates. Exterior doors need new weatherstripping to replace the old. The attic access should be weatherstripped to keep out unwanted attic air. Windows and trim should be caulked to seal. Window replacement would be optimum. Switches and outlets can be sealed with gaskets and caulk to reduce infiltration. Sills and baseboards need to be caulked also.

When replacing windows, install energy efficient units with a U-factor of .28 or lower and ensure that the rough opening of the window is properly air-sealed with a low-expanding foam that is approved for doors and windows. U-factor – This number refers to the ability of your windows to resist heat loss. It is the numerical reciprocal of R-value. Low-e – These coatings are applied to glass when windows are manufactured and help to reduce the window’s emissivity, which can improve insulating properties when properly applied. Gas filled – Noble gasses are used as an air barrier between panes of glass to help increase a window’s thermal performance. The seals that keep these gasses trapped inside can fail over time and should be inspected periodically. Your Energy Smart Analyst: Charles Cady (970) 379-2961 Single pane window with signs of deterioration . Double pane replacement doors with broken seals. Large expanses of single pane glass . Recommendations: Single pane windows are quite inefficient. Currently the windows have insulating shades and most have plastic window kits. Replacement would be optimum. Woodruff Residence 312 West Hyman, Aspen, CO 81611 Pitkin jeffrey@cloudhilldesign.com (970) 452-9008 5 Heating & Cooling Energy Smart Tip: Your home’s heating and cooling systems were inspected for safety and efficiency. Older heating systems should be replaced with energy efficient, sealed-combustion units or highly energy efficient heat pumps. This is often a significant upgrade so considerations beyond energy savings should be made. ENERGY STAR certified equipment will provide the best efficiency and savings. AFUE – Annual Fuel Utilization Efficiency is the measure of your heating system’s efficiency. Higher numbers are more energy efficient. SEER – Seasonal Energy Efficiency Ratio is the measure of your cooling system’s efficiency. Higher numbers are more energy efficient. Sealed combustion gas boiler Uninsulated heat pipes Recommendations: All exposed heat pipes should be insulated to reduce heat loss. Your Energy Smart Analyst: Charles Cady (970) 379-2961 Heating system type: Boiler-Baseboard Fuel: Natural Gas Efficiency rating (AFUE): 92 Recommended AFUE: Secondary heating system: Cooling system type: None Efficiency rating (SEER): Recommended SEER: Fireplace type: Wood Woodruff Residence 312 West Hyman, Aspen, CO 81611 Pitkin jeffrey@cloudhilldesign.com (970) 452-9008 6 Hot water system type: Indirect Fuel: Natural Gas Set temperature: 120 Solar thermal assist: N/A Pipes insulated?: No Existing EF: Recommended EF: Water Heating Energy Smart Tip: Many water heating systems are set to temperatures that are too high for safety and energy efficiency. Keep your water temperature at 120˚F for optimum energy performance and to keep your family safe. EF – Energy Factor is a metric used to compare the energy conversion efficiency of residential appliances and equipment. EF ratings vary by appliance size and type, but in general, bigger numbers are more energy efficient. Sidearm DHW tank with uninsulated pipes . Recommendations: All exposed hot water pipes should be insulated to reduce heat loss.

LEDs use about 20% of the energy and last up to 25 times longer than traditional incandescent bulbs. They also contain no toxic mercury and turn on instantly. Your refrigerator is usually one of the biggest consumers of electricity in your home. If your fridge is more than 10 years old, consider replacing it with an ENERGY STAR certified unit. Tips to reduce kWh base-load: 1)Use smart power strips for big energy users like home entertainment systems 2)Use laptop computers instead of big towers – they use up to 90% less power 3)Upgrade all of your appliances as they age to ENERGY STAR Your Energy Smart Analyst: Charles Cady (970) 379-2961 Seldom used wood fireplace .Infiltration at a wall outlet.See photo at left. Recommendations: When purchasing appliances choose ENERGY STAR models to reduce energy and water consumption.
