As a “Third Generation” licensed general contractor in Lake Havasu City and certified home energy rater through the Residential Energy Services Network (RESNET) and the Building Performance Institute (BPI) Trevor has worked with EPA’s ENERGY STAR for new homes program as well as both of UniSource’s Energy Efficiency Programs (UES Energy Smart Home’s and Bright Solutions program).
 

Evo Energy Solutions is focusing on perfecting the ENERGY efficiency of your home, by increasing energy performance we can help you decrease electric costs and put more savings into your pocket. In Lake Havasu we have started re-insulating many homes and this has decreased heat loss during the winter months.

 

HOW INSULATION WORKS
To understand how insulation works it helps to understand heat flow, which involves three basic mechanisms -- conduction, convection, and radiation. Conduction is the way heat moves through materials, such as when a spoon placed in a hot cup of coffee conducts heat through its handle to your hand. Convection is the way heat circulates through liquids and gases, and is why lighter, warmer air rises, and cooler, denser air sinks in your home. Radiant heat travels in a straight line and heats anything solid in its path that absorbs its energy.

Most common insulation materials work by slowing conductive heat flow and -- to a lesser extent -- convective heat flow. Radiant barriers and reflective insulation systems work by reducing radiant heat gain. To be effective, the reflective surface must face an air space.

 


Regardless of the mechanism, heat flows from warmer to cooler until there is no longer a temperature difference. In your home, this means that in winter, heat flows directly from all heated living spaces to adjacent unheated attics, garages, basements, and even to the outdoors. Heat flow can also move indirectly through interior ceilings, walls, and floors -- wherever there is a difference in temperature. During the cooling season, heat flows from the outdoors to the interior of a house.

To maintain comfort, the heat lost in the winter must be replaced by your heating system and the heat gained in the summer must be removed by your cooling system. Properly insulating your home will decrease this heat flow by providing an effective resistance to the flow of heat.

R-VALUES
An insulating material’s resistance to conductive heat flow is measured or rated in terms of its thermal resistance or R-value -- the higher the R-value, the greater the insulating effectiveness. The R-value depends on the type of insulation, its thickness, and its density. When calculating the R-value of a multilayered installation, add the R-values of the individual layers. Installing more insulation in your home increases the R-value and the resistance to heat flow. To determine how much insulation you need for your climate, use an insulation calculator or consult a local insulation contractor.

 


The effectiveness of an insulation material’s resistance to heat flow also depends on how and where the insulation is installed. For example, insulation that is compressed will not provide its full rated R-value. The overall R-value of a wall or ceiling will be somewhat different from the R-value of the insulation itself because heat flows more readily through studs, joists, and other building materials, in a phenomenon known as thermal bridging. In addition, insulation that fills building cavities densely enough to reduce airflow can also reduce convective heat loss.

Unlike traditional insulation materials, radiant barriers are highly reflective materials that re-emit radiant heat rather than absorbing it, reducing cooling loads. As such, a radiant barrier has no inherent R-value. Although it is possible to calculate an R-value for a specific radiant barrier orreflective insulation installation, the effectiveness of these systems lies in their ability to reduce heat gain by reflecting heat away from the living space.

The amount of insulation or R-value you'll need depends on your climate, type of heating and cooling system, and the part of the house you plan to insulate. To learn more, see our information on adding insulation to an existing house or insulating a new house. Also, remember that air sealing and moisture control are important to home energy efficiency, health, and comfort.

 

INFRARED CAMERA IMAGES

Here are a few pictures taken with our infrared camera showing missing insulation in a back bedroom of a home. The homeowners were complaining about the room being warmer than the rest of the house. You can easily see that the room wasn’t properly insulated. The second picture is of an attic knee wall you can see that the insulation has fallen and the red spots indicate the heat gain. This causes the air conditioning to work overtime to compensate for this loss. At Evo Energy Solutions we have the tools to solve problems and save you money.

 


 

Our Process / Advantage:

Evo Energy Solutions has a much different approach that the typical contractor. Because we understand the science behind the building we use the “Building as a system approach.” You understand that your car is made up of interacting components and systems – when one component fails, it affects the performance of the entire vehicle. That same principal also applies to your home?


High energy bills, uneven temperatures from room-to-room, drafts, moisture, mold, mildew, poor indoor air quality, pest infestations, seemingly uncontrollable humidity levels and even premature deterioration of building materials can all be the result of a breakdown in the relationship between the systems in your house – the building envelope (shell), heating and air conditioning (HVAC) equipment and you, the occupants.


If one system has a problem, it impacts the other systems’ ability to function properly. Treating the obvious symptom without knowing the real culprit behind it can actually make the problem worse or create new problems. Properly diagnosing and fixing the root cause requires a house-as-a-system approach based on building science.


Evo Energy Solutions will conduct a comprehensive whole-home assessment to find the real problems, then prescribe and prioritize improvements that make the system as a whole function at its best.
