A Deep Energy Retrofit

Full Details...

The details include a 30 page description of he design and construction process, a photo gallery, and a detailed thermal analysis spreadsheet.

NEW -- After 1 Year Report...

This is the most carefully thought out energy retrofit I have seen.  Gordon and Sue took a drafty 1963 brick schoolhouse with almost no insulation and converted into a home with a heating bill that is 6% of a similar size code built home in their area.   

Features include: R40 Larsen Truss walls, triple glazed R6 super windows, glazing revamped for passive solar heating, a new solarium, a hand crafted masonry heater, and much more.  In addition to a very good thermal envelope. Like most good designs, this one is simple and robust without a lot of gadgetry.

solar zero energy home

This is Greg's solar heated remodel in NM.  The combination of improvements to the homes' thermal envelope coupled with aSolar heat storage tank solar space heating system with lots of heat storage make this a zero energy home for space and water heating.  When the  planned PV array is completed, it will be a full net zero energy home.

NEW -- ''as built" plans for this home...

This is a very impressive less than net zero energy home in MA.  It actually generates significantly more energy than it uses.
It uses a combination of a very good thermal envelope, solar passive and active heating, solar water heating, and a PV powered heat pump to achieve this performance.

The UK is going to require that new homes be carbon emissions neutral by 2016.

This is one of the early cuts at such a home.

It will be interesting to see the designs that come out of this requirement.

Passive Solar Cooled House in Tropical Areas

http://kotaronishiki.com/

 

passive cooled house in tropicsThis is a fascinating house in Leyte Philippines that is passively cooled using a number of unique methods including a double roof, a strategy for shading south and north walls in low latitudes using the roof, and double walls on the east and west for shading.

The house also uses day to night temperature differences and basement cooled air as part of the cooling strategy.

This house is definitely worth taking a look at if you live in a low latitude hot climate.

User and Technical manuals for the engineered "I" beam studs and sole plates.

 

A very interesting solar home in the UK. 
Features include super insulation, passive solar design with an attached sunspace, heat recovery ventilation, efficient wood heating, 1300 gallon rain water tank, and a 1KW solar electric system.  All packaged in a  very open and appealing floor plan.
The walls are nearly 10 inches thick and use engineered "I" beams with thin webs for studs -- this provides very high R values and low thermal bridging compared to conventional studs.  Blown in cellulose is used for insulation.
The total energy use is about 4000 KWH per year -- about 1/4 of this is supplied by the current PV rig, with more planned.
Many pictures are provided.  The house is located in Sheffield/Nottingham/Derby triangle.
Hanover House

Mother Earth News Article, Issue 100  July/Aug 1986

An interesting article on a California desert house that uses passive solar and earth tube strategies to both heat and cool. 

"The design I used incorporates a bit of commonsense technology, some ancient architectural methods of the Middle East, and a smattering of Southwestern American Indian building techniques. The result is a structure that's almost wholly passive, uses native building materials where possible, and—this is quite important to me—leaves an almost indiscernible impression on the landscape."

"Secondly, when moving into their self-built houses - at least one person in every household must start his/her own business or telecommute. Hopefully, in time Friland will become a local power centre and a valid contribution to the regeneration of rural areas."
