In 1980, we offered the much smaller early version of our ZED book in hardcopy form.
In a few years, it grew too large to print, so we converted it to eBook form on compact disc (CD).
We have taken significant steps toward paperless business operations - No killing trees.

With widespread access to broadband communication links and video capability,
we have converted our ZED CD to immediate download (only) - No paper from killing trees,
No unsustainable petroleum-based plastic CD's, and NO WAITING FOR SNAIL MAIL.

Our goal is to leave a valuable lasting legacy

for a sustainable planet.

Our download material is over 400 megabytes (and still growing).
It takes a long time to download through slow-speed dialup (but it is possible).
We give you the option to download all-or-part of our ZED materials.
Study part of it, and then come back for more (within your download time window).
If you want a future eBook update, email us from the same email account ID as your original order.

Our popular two hours of videos are also available online at:



Comments from folks like you who have read our Zero Energy Design® materials:

From David in Arkansas:

 I used to build passive solar homes in Ft. Smith, AR.  I used your plans and your books and everything that I built is still working great.  The Mxxxx's home in Van Buren, AR. that  I built in 1984 used your plans. They are now 86 years old.  Last year they told me they have had a wonderful healthy 26 years in the home.  Through research I have found out that not only are these homes energy efficient they are also health efficient. 

From Ray:

I've been reading/ studying / collating/ designing / thinking/ about your Book... about All Things ZED.

I still have a lot more to absorb and blend in from your super ZED Book.  I'm an architect / designer trying to reinvent myself for the growing Solar economies. I thank you Mr. Hartweg, for your time.  

From Bob in Arkansas:

I previously purchased your Book. I have read it 5 times from cover to cover (so to speak). Some sections I had to read even more often. I have been actively working on changing the energy usage on my two homes ever since.

I imagine that you may not see the effects of your writings often, so I thought that I would write to say, THANK YOU. You have opened my eyes to so much. Your perspective and experience has been very helpful to me in my efforts to bring my energy consumption down.

After having succeeded at much of what you suggest, I am beginning to feel comfortable in energy saving. I suppose the comment that you made about working from the top down being a failure, and that working from the bottom up was the intended path today is right on point. I will be giving cash presents to a few of my friends with the proviso that they buy your Book. At the moment, they have somewhat of a glazed look in their eyes when the subject comes up, but the changes in performance of my houses cannot be denied.

From Terrah in Tennessee:

I bought your book. Thanks for making your ZED information available to a mother trying to encourage her children to tread lightly on earth.

From Jerry and Janet:

Our names are Jerry and Janet. We’re Permaculturists. Jerry is a 3rd generation musician (Drums/Guitar/Bass/Composer/Recording Engineer (I’ll need a studio facing the solarium)/keyboards/violin. Both of us are teachers. We’re learning a lot through Your ZED CD ROM. We hold Masters degrees and are avid researchers of what interests and then motivates us.

We've tried some ZED principles on our home (we didn't use A/C this summer b/c shading on south side/backyard made conditions bearable).

From: Pat and Larry:

ZED Master et. al. Pat and I are studying your cd and we are becoming ZED advocates. Gratefully, you have spoiled us for any other type of design. Thank you.   

You have lots of great tech info, and a lot of articles that we already agree with.   

Thanks again for you life dedication.  Two new advocates,
