HALF?!? That's a SERIOUS Number! What type of efficiency design mods/equipment upgrades are able to achieve these results, and what are the standard building practices/designs/materials you're comparing it to?

It’s a question that would require more bandwidth than Para would want but here it is in a nutshell. A standard code built home is assigned a HERS Rating of 100 and a home that tests out to let’s say 50 will be twice as efficient as that. See here for more info. https://www.resnet.us/about/he...%2520increase%2520it. Basically it starts with the design but that can be adjusted to virtually any home. Then there are framing details like California corners, 2x6 framing, outsulation, etc. that contribute to the home’s ability to be properly insulated. When you really insulate a home well than you have to introduce an air exchanger to keep fresh air in while exhausting stale air. There are several steps that need to be accomplished. There is an 8 page checklist that the independent HERS rather uses to verify things are done properly. At the end of the project the house is tested for air tightness. This is referred to as ACH. It stands for air exchanges per hour. Houses built 10 or more years ago have an ACH in the range of 7 to maybe 20. Modern regular code usually requires an ACH of 5 or below. Our homes usually tested out between 1.5 and 3. These improvements allow your HVAC company to conduct what is known as a Manual J Calculation and typically will allow a 50% reduction in the size of your HVAC unit. That coupled with a high efficiency unit of say SEER 2 rating of 18 or better will really reduce your utility bill. These are only a few of the things that need to be done but it is doable and well worthwhile. The key is finding a firm that is ENERGY STAR qualified and experienced with the techniques. ------------------ Eddie Our Founding Fathers were men who understood that the right thing is not necessarily the written thing. -kkina | |||

Thank you Very little |
Yes, then it's feasable to put solar onto the house only after you maximize the HERS rating and get to the lowest amount of power required per month on averge. At that point you can put in a lower cost solar system. This I would only do on a new build where the solar cost can be factored into a mortgage and eliminate a monthly fuel bill. Fuel costs never go down from power companies, on a new build you have the opportunity to reduce your needs and replace the power company all at once. | |||

I ‘assume’ the location(State) of this new home is settled? To me, that’s as important as the house details. Sorry if I missed that part. | |||

Considered solar? Our home is about 2,300 sq.ft. and we have a pole barn (2,100 Sq.ft.) The house is a ranch, 3 bedrooms, 2 bath. Lots of covered porch attached. - the solar idea - we had an 11kw system put on our barn roof. It cut our electric bill by 75 percent. We are in Pennsylvania. 8-9 months of the year we don’t have an electric bill. Another thought - geothermal HVAC? I believe one of the most economical systems for heat and AC. | |||

I had the solar put on the roof after the house was completed. ________________________________________ -- Fear is the mind-killer. Fear is the little-death that brings total obliteration.

If possible get your natural gas line inlet as close to your electrical inlet as possible in the event you decide to install a back up generator system to reduce install cost. | |||

It's pronounced just the way it's spelled |
My lovely wife chimed in with “make sure all the wiring uses the standard for wiring insulation colors, and does so ALL through the house” based on our many experiences with putting in lights, ceiling fans, etc. in various houses. My favorite was orange, yellow, white and white with some odd color stripe. | |||

Looks like CT adopted the 2021 IECC, so it's going to be a pretty tight house whether you like it or not.

We built ours in 2015, my advise is 6 inch walls and insulation, the more the better. That has saved me a ton in utilities. I’ve since added solar, expensive but has a payback time that can work to your advantage depending on utility costs. “Government exists to protect us from each other.
