| Passive Solar Homes -- 91 new
award-winning, energy-conserving single family home plans, U. S. Department of Housing and Urban Development, 1982
|
This
is (I think) a really interesting and useful collection of passive solar
home plans. It came out of a competition that HUD sponsored in 1982 for passive solar home designs. These 91 award winning plans were selected from more than 500 entries by builders, designers, and architects. This was a very active time in passive solar home design, and the plans show a high level of innovation. This is the first 30 -- rest to come as time allows. |

A
plan book of affordable passive solar homes from Appalachian State
University. Sizes range from 900 to 1300 sqft, and all include passive
features such as south glazing with overhangs for summer overheat
protection, thermal mass floor slabs, carefully thought out wall and ceiling
details to reduce heat loss and allow good insulation. The modest size
of these house, coupled with using only the most cost effective solar and
energy saving features makes these homes both very energy efficient and very
affordable. Good job ASU!I'd think about adding or making provisions for solar water heating, and, perhaps a whole house fan for summer cooling if you have cool nights. Each house has a downloadable full plan set available -- all free. |
| Lakeland, Florida -- Side by Side
Test, Florida Solar Energy Center Comparison of energy of a home designed with many energy efficiency features to a same size conventional construction home.

This
is a very detailed and carefully done study of two houses of the same size
in Lakeland Florida. One house was built conventionally, and the other
was equipped with a wide array of features to reduce energy consumption,
including: reflective roof, internal duct system, thermal mass inside
insulation, high efficiency and properly sized AC, well designed
overhangs, and optimal windows. The measured energy consumption was 70% less on the house with low energy use features. A solar PV system offset and additional 22%, bringing the net energy use to near zero. The reports provide quite a bit of detail on the saving achieved by each energy efficient design feature. |

| Habitat For Humanity Zero Energy
Demonstration Home in Denver Description of home: Energy use report:
|
This
Habitat for Humanity home is similar in size to the one just above and is in
the same area, but has additional features that result in further net energy
use -- in fact, less than zero net energy use. Added features include double stud R40 walls, R60 ceiling insulation with raised heel trusses, R30 floors, enhancements to solar water heating system, more attention to air tightness, more attention to glazing, and a PV system increased from 1.8 KW to 4 KW. The 2nd link shows that the natural gas uses for space heating and backup water heating is more than offset by the PV array generating excess electricity which is sent back to the grid -- so, net energy use is less than zero. It would be nice to see how well each of the energy saving/generating features pay on their own. |

From the Architecture Week article:
"It's
an environmental dream: a self-reliant house that produces its own
electricity, water, and cooking gas. Solar energy powers the
air-conditioning, lights, and household appliances. Rain, dew, and
condensation from the cooling system produce enough water for a family of
four. Recycled water irrigates the garden, and surplus electricity is sold
to the power company or used to drive an electric car 30 miles (50
kilometers) a day." |

Earth News Article, Issue 91 Jan/Feb 1985An article describing a scheme for passive solar heat storage on an annual basis. The scheme uses a large "bubble" of dirt around the house that has a good thermal connection with the walls of the living area, but is isolated from the surrounding dirt by insulation and waterproofing. Over time the temperature of the dirt bubble can be brought up to a comfortable temperature that varies only a few degrees over the year. More information and a book on this scheme is available here: Here is a review of John Hait's Passive Annual Storage book by by Nick Pine. |

Florida Zero Energy Test House Florida Solar Energy Center The Report (pdf)

A
home constructed in a very difficult cooling climate (central Florida) to
see if a combination of passive cooling techniques to reduce heat gain, high
efficiency AC, efficient appliances, and a fairly large PV rig could produce
near zero net energy use. The home was largely successful in
meeting these goals.Net energy use was only about 18% of a control house built to current codes. Pretty good detail on how much energy each feature saved. My 2 cents would be that the passive cooling, high efficiency AC, and efficient appliances contributed 67% the of the savings, while adding little to the cost of the house. The 4KW PV rig contributed the other 33% of the savings, and probably cost about $40,000. |

RuralZED - The Zero Carbon House Is Ready
Detailed Description:

This
is a very carefully thought out design that meets the UK requirement for new
homes to be zero carbon by 2016.Many interesting features including prefab construction, flexible layouts, a base design for the near term that is affordable and yet can be upgraded over time to the full zero carbon requirement. The houses are planned to fit into eco villages rather than thinking solely in terms of single family, detached designs. The website is in work, but the "Full Brochure" pdf gives a pretty detailed rundown on the whole concept. |

steps that will reduce new home energy consumption by 65% by 2015.
Energy efficiency requirements for new homes are increased each three years
starting in 2006 with a specific set of energy efficiency features."Zero
Energy Capable" means that energy use is sufficiently low that it could be
completely offset by local generation -- e.g. a solar electric generation
system. |

energy through good insulation levels and passive solar design. The
homes also include a grid tied PV system that offsets some of the homes
