As Green Building begins to reach out and grasp the attention of consumers, builders, lenders, etc. - The terms commonly used appear to be getting used interchangeably. I think this is creating confusion and misunderstanding. It is very important to understand the marketing behind the words.
I was speaking with a builder earlier today about Residential Construction in the Green Community and we were talking about the differences between certain products. I thought it would be a good topic to write on. Here are the items that jumped out at me.
When Green Building first started it brought together many topics. Environmentally Friendly, Energy Efficient, Recycled Products, Low Toxin and other products that are considered to make a Healthier Environment. Now that the number of products available grows, we are seeing various new categories develop:
- Energy-Efficient- a good example would be Energy Star
- High Performance- a good example would be one built with ICF's
- Green- built with a variety of products
- Homes with a mix of these. One example would be LEEDwhere it starts with design like a High Performance Home and can use Green products such as Low VOC Paints, Recycled Flooring, Solar Tube, Solar Panels, etc. Follow the link above to learn more about LEED Certified homes.
Now, for the difference between a High Performance Home and a Green Home. Can a home be both of these, absolutely, and often times they are. The purpose of this post is to be able to understand what the difference is between a home marketed as a High Performance Home and Green Home.
JaneAnne Narrin of EcoSteward Realty in North Carolina wrote and excellent post on High Performance Homes that I invite you to read. To summarize, the High Performance Home starts with design. These homes are going to be a very Tight Construction called the "envelope". Due to the tight "envelope" the home will need more attention to Air Circulation and transfer of indoor/outdoor air. Indoor Air Quality (IAQ). Here are the some of the key points for a High Performance Home:
- Energy Efficiency
- Water Efficiency
- Indoor Air Quality Efficiency
- Site Planning and Lot Development
- Homeowner Education
These homes are what I would call, with my slang, an Ultra Efficient Home. You will see a difference in your Utility Savings and there should be a significant reduction in allergy and asthma symptoms. Believe it or not High Performance Homes built with Insulated Concrete Forms have shown that the larger the home, the more efficient it is. Typically these will not have Wood Framing which also makes the Fire Rating of these homes amazing.
Now, a GREEN Home. We have gone in past years from GREEN being only Environmentally Safe Products, then Green was affected some by Greenwashing, and now Green Products are even more environmentally safe than typical products (i.e. recycled, less wasteful manufacturing, etc) and we are finding they are better for us too. Thus making the difference between a High Performance Home and a GREEN Home. Here are some things you might find on/in a GREEN Home:
- Some WILL have wood framing
- Bamboo or Recycled Flooring
- Perhaps Recycled Insulation
- GreyWater System (capturing rain water for household use)
- GeoThermal Technology
- Special Roofing Materials
This is just a SHORT list. But you will see that a GREEN HOME uses materials that are really GREEN, like the recycled products. These will also be Energy Efficient while utilizing Environmentally Friendly Products.
As I said earlier, there will be homes that combines features from both systems. I hope that I have cleared up some of the confusion so that now when you see High Performance Home or GREEN Built Home, hopefully you will have some ideas on what to look for. If you are wanting to build, pick out the aspects that are most important to you. It doesn't have to be one or the other. It could be Hybrid so to speak.

Let me know if you have any questions. If I don't know the answer, I will find one. :)
Thanks Mary for your help!
Stephanie! It looks great! I'm glad you posted this because these terms do tend to get confusing!
You make a very important point, "If you are wanting to build, pick out the aspects that are most important to you. It doesn't have to be one or the other. "
What works for you in Texas where you have a lot of heat may not work so well for me in Michigan where we have 4 seasons and very little sunshine during the winter months!
Excellent post!
Stephanie,
A lot of these products are great products whether they are green or not! Bamboo floors are just beautiful. Geothermal heat can slash your energy bill in half or more depending on where you live. I hope some of these like geothermal heat become more accepted so that the initial price comes down. Right now the high initial cost of some of these items deters many buyers and builders from using them.
Hi Paula, I'm glad it helped.
Hey Thesa, you are very fortunate. :) Thanks.
Hi Chris, I still think there are a lot of misconceptions regarding green..like price. For instance, one can buy a High Performance Home for about 10% more, sometimes less. So, on a 200,000 home it would be 20,000. (just because I like round numbers) ...how much would that affect mortgage? and the utility bills would be maybe...I've seen different reports..45% less. I think it is all about educating the consumer.
Ok..Jeff, I waited because I thought this might be a long one. :) My conversation with the builder yesterday morning was along the same lines. It really is not that clear cut. I agree. There are many homes that have both characteristics. We were talking about how green and high performance homes were being thrown in to the same basket....which is starting to give a misleading name to "green" homes and how High Performance Homes are really breaking off on to their own group. I challenged this a little as well, but it made a lot of sense. Should I change this somehow.
Stephanie,
Thanks for clarifying the two. I see a lot of builders advertising green homes now I can really pick out which ones are green and which ones are high performance.
Hi Stephanie -
I'm just reviewing notes from my conference with Mike Holcolmb. Mike was instrumental in putting together Green Built (TM) Michigan.
We had a very similar discussion and when I asked his definition of "Green" his reply was,
"Green is a collection of things. A system for energy efficiency. "Green" homes are designed and constructed to ensure
The program used for certification will have recognizable and measurable controls to insure that it meets a set standard." Standards for programs are derived by consensus from a community of individuals.
A Green home must address the needs of the occupant, as you said in your article. Mike feels the biggest factors to the occupant would be
(not neccesarily in that order).
Again, just one individual opinion.
I think your article creates a very good awareness that we all have different ideas about "green" and "high performance". The comments you have received also reflect that. We need to be careful not to become too specific in our classifications. It's all good!
Hi Mary, I agree. I thought this would be a good way for people to know the difference when a home is being marketed as either a "High Performance Home" or a "Green Built Home". There are many builders that are going in between, which is great.
I just wanted to put this out there. With all of the recent talk regarding High Performance Homes I thought people may want to know a little about why it's somewhat different.
By the way, did all of you read the article regarding ICF's in EcoStructure Magazine this month? It's a GREAT article.
Stephanie~
Now THIS is quite an interesting and informative post...I know a batch o' REALTORS (of the ECO kind) who would love to see this all plotted-out and numbered and with a rating scale attached.
Thanks Wayne and Linda!
Hi JaneAnne, that would be a great idea wouldn't it. :) I am working on some pretty neat posts right now. I have had an amazing week and received a lot of GREAT blog fodder.
Hi Jennifer, you are probably right. Homes can have BOTH features, but because of instances like what you are saying...it's exactly what the builder was talking about the other day. Hybrid Homes is a builder in MI but he has THE PERFECT name for it. You can contact me anytime with questions. I'll help the best I can. Good Luck with it.
Hey Sally, I bet Hawaii is doing some great stuff too. I'll try to find a good product for you to go see there.
This is a very educational post. Thank you for all the work you put into this post.
Chris- Bamboo is a greener choice because it is a renewable energy source. It can be harvested and regrows very fast! I am not sure of the stats but it is amazing!
We have the tankless water heaters and love them! We live in Florida and they work very well here because the ground temp water is warm. The same is true for Hawaii. In fact the company we bought them from are in Hawaii and Florida.
Hi Dena, by all means...please! :) I'm learning more about Bamboo floors right now. Add anytime. My fellow EcoBroker!
Hi Beth, Green is hitting many areas of the nation right now so it's important that we as agents stay informed as well. You never know when you might get a green question. :) Thanks for the great compliment.
Stephanie,
How about "High Performance Green Home" as a hybrid term.
I actually had not thought Green and High Performance were different. Thanks for making me aware of the difference. This is a great blog!
I have been a high performance building guy for a while now. I got into energy auditing as a new branch of my home inspection business. So saving energy and building performance have been my focus. It did not occur to me this was in fact not Green.
Someone had discussed cost. This is where many people lose interest in having an energy audit because they can not understand investing in their home. They want to lower their energy bills, but when they find out a professional assessment of the home cost several hundred dollars, they opt out.
You had said a Green home on average costs about 10% more to build than a conventional home. Is there a pay off over the life of the mortgage that makes this a good investment? Do people balk at spending more money up front to be Green?
The pay off for high performance is lower energy bills which out weigh the higher mortgage payment. I would guess the same is true for Green.
Again great educational blog. I'll be visiting here often.
Stephanie,
You blog is great, don't second guess yourself. Writing is an evolving process. I have revised so many pieces I have written. Just part of learning.
Geothermal is costly here, but has been used. I have not personally seen a house with a system installed.
ROI is the key to any of these types of homes. There comes a point where the upgrades do not justify the expense.
Hi James, I agree about costs. Mary Bigelow yesterday related this to CD's and CD Players. Once the demand came around the prices dropped significantly. Also, there is a point (like was mentioned to me yesterday by a builder) where since the products are still new that there will be vendors that feel the need to price gouge.
Thanks again.
This is an amazing post and one of the many reasons why I keep coming back to your blogs. I learned something and it was painless. :)
I look forward to many more blogs like this.
Stephanie, amen to the "hybrid" of the two. Being GREEN has more to it than simply being environmentally wise. Being GREEN is also about being economically wise. We love our GREEN earth, but we are wise to watch how much GREEN is leaving our pocket books as well.
So watching all aspect of the GREEN issue is truly the only way to go. We must remind ourselves that being GREEN is a very BIG and complex issue, and we should do all that we can to be educated on as many aspects of it as possible, or be sure to hire those that we trust to be that professional for us.

Thanks Pamela, what a great compliment! I am glad it was helpful.
Hi DJ, Absolutely! It is complicated and very important to hire the experienced and educated when building/buying green. These homes work as systems and it is imperative to make sure the systems work/installed properly. Great comment!
Hi Michael, You bring up a very good point. It is very important to make sure the glues have less/no toxins. Thank you for bringing that up. Good luck with your flooring!
