Summary

Mr. and Mrs. Smith; Thank you for allowing me the opportunity to inspect your home. You have a beautiful home in a great neighborhood. There are three sections of this report beyond the summary which detail the energy efficiency of your home. The first section titled Current Performance lists the major components of the house and their energy consumption as well as details about the blower door test and air tightness limits. The second section titled IR Report are the infrared photo’s and notes about air leaks, under-performing insulation and other prominent items identified by the infrared camera. The third report titled Home Energy Retro-Fit lists some suggested improvements and their potential energy savings Homeowner reported issues: Fireplace: After inspecting the fireplace and a reviewing the installation instructions I feel confidant in saying the unit is missing the actuator arm controlling the combustion air intake. Not having the ability to close the combustion air intake leaves a 3” diameter hole open to the outside. Installing the actuator arm at this point may prove to be costly and time consuming. The quickest and easiest solution would be to simply seal the outside air intake until actually using the fireplace. Dinette – draft at back door: The infrared photos did not show any smoking gun’s as far as air leakage at the back door but some air leakage was noticeable. What the photos did show was air leakage at the bottom of the wall. Add the small amount around the door and the small amount along the bottom of the wall and a stiff North wind and you will have a sufficient amount of air infiltration that would be noticeable during the winter. A practicable and inexpensive solution would be to pull the base shoe trim along the outside wall and simply foam the area under the base trim. A slightly more involved solution would be to pull the vinyl siding off from the exterior and tape/seal the wall to floor connection and reinstall the siding. Second floor is warm during the summer: As the infrared photos show there is a significant amount of warm air infiltration that is taking place. The most notable concerns are the wall to sealing joints and the duct work that runs through the attic. Sealing up these areas would be a priority for improving the comfort of the second floor during the summer and the overall energy efficiency of the house.

Test Results: Blower door test results were 1800 CFM of air leakage at 50 Pascal’s of pressure. In realistic terms, if we were to add up all of the penetrations allowing air infiltration it would equal a square hole approximately 10” wide x 10” tall. A more practical example would be the infiltration is costing you about $204.00 a year in heating and cooling costs. Break down of the Top 5 Most Energy Consuming Building Components. Above Grade Walls $292.00 Foundation Walls $265.00 Duct Leakage $211.00 Infiltration $168.00 Windows $165.00 Recommendations: HVAC – Given the age and efficiency of your current furnace significant energy savings could be achieved with replacing the unit with a 95% efficient unit. Upgrading the furnace could save you upwards of $200.00 a year in heating bills. Some units are eligible for federal tax credits and would be safer for your family with the power vented exhaust. Basement Walls – Although energy loss in the basement may seem an unlikely place to consider insulating, remember an 8” thick concrete wall has an insulating value of about R2 and is constantly exposed to temperatures different than what is being maintained indoors with the most significant energy loss occurring at the top 4’ of the walls. Air Sealing – A question that always arises is “can a house be too tight?”, and the answer is yes. The home needs a certain amount of outside air on a consistent basis to maintain good indoor air quality for the occupants. The building science community including government building codes and the American Society of Heating, Refrigeration and Air-Conditioning Engineers (ASHRAE) has established minimum ventilation standards for homes. Currently your home is at the minimum threshold of the standards which is one full air exchange every three hours. Additional air sealing measures would improve the energy efficiency of your home but should be done in consideration with adding a managed ventilation system to maintain good indoor air quality. There are many types of systems available but keep in mind the goal is to introduce fresh air in a manner that is cost effective and does not undermine energy efficiency. I have attached a specification sheet for a Broan energy recovery ventilator that I have seen in use for new construction homes for over 10 years with very good results. Air Ducts in Attic - There are a number of cold air returns that traverse through the attic that are not sealed. The unsealed joints allow for unconditioned air from the attic to be pulled into the HVAC system and degrade the performance of the entire system. ALL the joints and connections should be sealed with Mastic or UL approved foil backed tape.


www.iesgreen.com

Attic – At a minimum an attic should have sufficient insulation to achieve an R-38 insulation value, this is only the minimum, R50 is recommended. Currently your attic would rate about R-20. Due to the simple principle of warm air rising and accessibility, one of the most effective places to increase the energy performance of your home is at the attic. When it comes to increasing the performance of the thermal boundary at the attic not only do you want to attain a high R value but you must air seal as well. Any location where air can pass from the conditioned area of the house to the attic should be air sealed. This would include sealing around all penetrations such as plumbing pipes, electrical connections and light fixtures. Most notable in your house was the air leakage at the wall to ceiling intersections, air sealing these areas would be a priority prior to adding insulation. Please refer to the photo where you can see the wood framing and drywall on each side of it. Those types of areas are considered thermal bypasses where conditioned air is escaping from the house into the attic and in the opposite direction during the summer. The air is also escaping into the wall cavities and causing the insulation to under-perform. Simply covering the area with fiberglass insulation is not enough. Fiberglass insulation is an insulator and not an air sealer. Fiberglass works on the premises of trapping air and holding it. If you allow air to pass through it you are allowing for its performance to be degraded. It is also very important to install soffit dams and wind baffles at the eves to block the wind from blowing through the insulation yet maintaining ventilation for the attic. The key is to eliminate air movement into the insulation. Fiberglass is an effective insulator only when it can trap air and hold it. Windows – Replacing all three basement windows with energy efficient units that have a U value of .30 or lower and a SHGC value of .30 or lower, would save you about $58 a year in energy bills. Many replacement widows are also eligible for federal tax credits.

Other Suggestions: Hot Water One of the most cost effective ways to save money on hot water heating bills is simply to install low flow shower heads and faucets. EPA’s Water Sense web site provides many great ideas for saving water and saving money on water heating bills. http://www.epa.gov/watersense/ TAX CREDITS – Currently the Federal government has tax credits available for improving the energy efficiency of your home although individual tax situations may very, we encourage everyone to consult with their tax advisor and review specific tax credit information at; http://www.energystar.gov Thank you again for the opportunity to inspect your home and please feel free to contact me should you have any questions.

Home Energy Retro-Fit

The Home Energy Retro-Fit report lists changes, or retrofits, that you can make to your home to save energy andmoney. Acting on the energy retrofit recommendations will make your home more comfortable, more valuable, andmore affordable.

Intelligent Energy Solutions recommends these retrofits, based on data gathered in a detailed inspection of your home. If you desire more detail on the retrofits or the cost estimates, contact Intelligent Energy Solutions, which provided youthis service.

Energy Retro-Fit Table

The Energy Retro-Fit table shows a package of energy retrofits for you to consider. Both the individual and total annualsavings are based on the whole package. You can see how good of a financial choice these measures are by lookingat the last column.

* SP is Simple Payback: the number of years until the retrofit has paid for itself.

** The monthly finance cost is the monthly payment, including interest, that will pay for all the tabulated improvementswhen financed with a 10-year mortgage at 6.00%.

The home's energy efficiency is rated using the HERS Index as defined in the RESNET "Mortgage Industry National Home EnergyRating Systems Accreditation Standards," 2006. An Index of 100 represents a home that meets current energy codes. A lower Indexindicates the home uses less energy than a code home, a higher Index indicates the home uses more energy than a code home. Therating considers all energy use in the home. The rating should be used only for comparison, since it assumes average climate andthermostat settings, quantities of hot water, and internal loads for a typical household. Energy costs are based on local energy prices atthe time of rating. If energy efficiency improvements are made to the home, or energy prices change significantly, the rating andannual energy costs may change. Although every effort has been made to provide accurate information, this rating does not constitutea warranty, expressed or implied, about the energy efficiency or operating costs of the house. Estimated savings are calculatedassuming that the improvements are implemented in the order listed, and in accordance with all local codes and standards. The costestimates for improvements are established by the local HERS provider.



Energy Costs by End-Use

The Energy Costs table compares the "before" and "after" annual energy costs to show energy cost savings. Itgroups retrofits by "end-uses," which are broad categories of how energy is used (or generated) in a home. Note thatPhotovoltaic panels (PV) generate energy, so as a result this "end-use" shows negative costs, if present.

The Total Costs bar chart gives a visual sense of how the annual operating costs of your house could change byincorporating all the listed energy retrofits.

The HERS Index bar chart provides a snapshot of your home’s energy efficiency before and after retrofits. The HERSIndex shows the energy efficiency rating of your home, similar to the way a miles per gallon rating shows theefficiency for a car.

Some retrofits interact with one another, and the total savings offered by each can change if the package ofcombined retrofits changes. For example, if you increase the insulation of your home, the energy savings you can gainfrom installing a more efficient furnace will be less than if you only install the furnace. However, the total savings willbe greater if you choose both retrofits.
