"We contacted Voltaire Engineering, Mr. Dan Rosenbaum, when we were preparing for a major remodel of our house.
It started with an energy audit but that was by far not where it ended.
After installing a new foam insulation in the roof/ attic area and exchanging the bedroom windows, we discovered a drastic reduction in our utility bills. Thanks to the advice we took from Voltaire Engineering.
Later in the process of remodeling, Voltaire Engineering did the electrical work and we couldn't have asked for a more engaged contractor. Whenever we discovered something unexpected, and we found plenty, Dan and his team reacted in our interest, showing us options and presented solutions.
Dan's biggest goal was, getting the job done, even if he and his team had to work longer or on the weekend.
If there was something he couldn't do, he sure knew somebody who was able to.
Living in the house during the remodel, as a stay- at- home- mum with a toddler was challenging, but Dan and his work crew did everything to make it as easy on us as possible. There is little privacy, if you remodel all your bathrooms, people are running through the whole house, and it helps to see, that they treat your belongings (and your dog) like you would. It helps, that you get called in advance to get a heads up, that they clean up after work is done, that nobody is yelling and screaming through the house, that you were treated with respect.
We recommend Voltaire Engineering, whenever we get an opportunity, and we hope this review helps you, as a future customer, to feel confident.
If you pick Dan Rosenbaum, you will be picking a good one."

"Voltaire Engineering, Inc. completed a home energy audit for me. I was very happy and surprised with the thoroughness of their inspection and follow-up report. They arrived on time, were very pleasant to work with, took the time to explain what they found and answer all of my questions. I highly recommend Voltaire Engineering, Inc. for home energy audits."

Energy Efficiency Auditing FAQs, answered by experts

Yes, skylights can affect a home’s energy efficiency, either positively or negatively. Properly installed, energy-efficient skylights with Low-E coatings, double glazing, and UV-blocking glass can help regulate indoor temperatures and reduce heating and cooling costs. However, poorly insulated or older skylights can contribute to heat loss in winter and excess heat gain in summer, lowering overall energy efficiency.

ENERGY STAR®-certified windows are the most energy-efficient windows on the market. This certification means that the window meets strict efficiency guidelines set forth by the Environmental Protection Agency. While they might cost more upfront, they can save you money on your energy bills in the long run. ENERGY STAR®-certified windows lower household energy bills by an average of 12% annually.

Setting your AC unit to 78 degrees can, indeed, help you save energy. In fact, according to experts, every degree you turn the unit up could save you between 1% and 3% on your energy bills. That said, turning your unit off entirely while you’re out might actually be less efficient than keeping it on at a higher temperature. Why? The unit will need to work extra hard to cool the house back off again after all those hot hours. 

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.
