Our house was designed by my Architect father and was built in 1979. It's in Groton, MA. Currently we have the original 33 year old HS Taum tankless oil/wood boiler…
I am designing Eco-friendly passive solar homes in southern New Hampshire. These homes will use active solar as well. I do not want to use fossil fuels on this project.…
building eco-friendly homes/Cathedral ceilings & insulation I'm designing and building passive solar slab homes (6-8" concrete floors) which range from 1000-1700 s.f. in Jaffrey New Hampshire area. The framing will be Advanced Framing 2x6 24 oc exterior walls, 2x4 interior walls and 2x10 rafters. Most of the houses will only be 20' (true south-North) deep due to sun penetration. My roof pitches will be 8, 10 & 12 depending on the design. There will be no attic space only insulated cathedral ceilings with lofts. There will be also be ridge and soffit vents. I am leaning towards the National Fiber Cell-Pak Cellulose for insulation. I like the fact that it is made from recycled newspapers and borates. I would like to use the ZIP system sheathing with Metal roofing & gutters for rainwater harvesting and also the Zip system for the walls. The siding will be fiber cement. Your input on the following questions would be helpful: Have you used the Zip Roof and Wall sheathing and how do they hold up with metal roofing? Regarding energy savings is there a real difference using 2x12 rafters rather than 2x10 rafters? What is the best non toxic insulation for cathedral ceilings? Is National fiber cell-pak cellulose a good fit? From the above sound board it's a little bit confusing. Thanks,

advanced framing etc As a new residential sustainable designer I have researched and studied advanced framing. A great site to look at is www.buildingscience.com. The site is very informative. 24 oc. framing has been around for 100's of years under different names. I for one believe in trying new techniques. Everything has a price. Double walls are a huge upfront expense and a waste lumber and other materials. The majority of builders can continue to build their cookie cutter style colonials where all the windows face North because that is the front of the house: Waste materials so they can have their super insulated houses that are full of toxins which compromise the health of the inhabitants. All for what? I for one will never follow their train of thought. Working with people who have a passion for sustainability (not just energy efficiency) is key. It all comes down to designing a home around solar gain and the site. Followed by using innovative materials and construction methods that are sustainable and non toxic.

Thanks for writing. When I had the window open I had my heat off-last year. We are burning the same amount of fuel with windows closed but the cost of fuel has risen over $1/gallon which hurts. I need to speak to Eco-friendly HVAC companies. I am also looking at Pellet Boilers. What do you think of them verses oil or natural gas? I will look into an energy audit as well.
