"Jonathan handled our Home Energy Audit and did an excellent job. He was on time, did exactly what he said he would do, and was thorough in his work. I appreciated his relational approach to Eco Three's work. He clearly communicated with me throughout the process and offered solutions for our home moving forward.

Energy Efficiency Auditing questions, answered by experts

R-value is calculated by dividing the thickness of an insulation material by its thermal conductivity. The material's composition and density influence thermal conductivity. Materials with lower conductivity values provide better insulation. The higher the R-value, the better the material is at insulating, helping homeowners select insulation that meets the energy needs of their climate and home layout.

R-value measures an insulation material's thermal resistance, indicating its ability to resist heat transfer. A higher R-value signifies better insulation performance because the material is more effective at slowing heat flow. The R-value depends on the type, thickness, and density of the insulation material, such as fiberglass, foam, or cellulose. Each inch of insulation typically provides an R-value between 3 and 8. There is no single universal R-value; the optimal choice depends on your climate zone. Colder climates require a much higher R-value than warmer ones to maintain energy efficiency, keep the home warm in winter and cool in summer, and manage costs.

Smart glass doesn’t use a lot of electricity, and you can expect a standard window to add between $1 and $2 per year to your electric bills. Smart glass is proof that energy-efficient windows work. Although your smart windows may consume a little energy to operate, they can save enough energy to offset the costs. If you’re concerned about the minimal bump to your electricity consumption, you can opt for smart tint, which doesn’t require electricity to work.

Attic and whole-house fans improve a home's energy efficiency and comfort. They ventilate hot air from the attic, which reduces peak cooling loads, lowers reliance on air conditioning, and decreases indoor temperatures. This improved air circulation and expedited heat exit helps lower cooling costs, balance moisture levels, and enhance overall natural airflow, contributing to the efficient operation of other home equipment.

Hawaii is currently rated as the most expensive state for utilities. How much are utilities for a house in Hawaii? With electricity costs in Hawaii totaling nearly 42 cents per kilowatt-hour, residents are paying more to run their households than any other residents. Electricity costs in Hawaii are so high, mostly due to the fact that most of the electricity available to residents is produced using oil that must be shipped in from other places.
