Passive solar heating and passive cooling-approaches known as natural conditioning-provide comfort throughout
the year by reducing or eliminating the need for fossil fuel. Chiras explains in methodical detail how today's
home builders can succeed with solar design.
This text presents a relatively nontechnical description of passive solar heating and cooling principles that can
be used in the construction of homes heated and cooled simply through the absorption or dissipation of sunlight.
The author, who has designed a number of these homes, discusses region-specific design strategies, the integration
of environmentally friendly back-up heat, the maintenance of indoor air quality, and step- by-step design processes.

Shelter, like many other elements of human existence, comes at an extraordinary cost to our planet and its inhabitants.
In the US alone, construction of 1.2 million new homes a year results in a massive drain on the Earth's natural
resource base. Today, nearly 60 percent of all timber cut in the US is used in building houses. Not to mention
construction wastes and the huge amounts of resources used in the day-to-day operation of the "modern"
household. In addition to environmental costs, there are the personal economic costs -- the thousands of dollars
each home owner spends each year to heat, cool, and power our homes.Today, a new generation of architects and builders
is emerging, intent on creating homes that meet human needs for shelter while causing only a fraction of the environmental
impact of conventional housing. The New Ecological Home provides an overview of green building techniques, materials,
products, and technologies that are either currently available, or that will be in the near future. Author Dan
Chiras provides a wealth of up-to-date, practical information for home buyers, owner-builders, and anyone interested
in building for a sustainable future.Included are chapters on: The Healthy HouseGreen Building MaterialsWood-Wise

Passive solar heating and passive cooling--approaches known as natural conditioning--provide comfort throughout
the year by reducing, or eliminating, the need for fossil fuel. Yet while heat from sunlight and ventilation from
breezes is free for the taking, few modern architects or builders really understand the principles involved. Now
Dan Chiras, author of the popular book The Natural House, brings those principles up to date for a new generation
of solar enthusiasts. The techniques required to heat and cool a building passively have been used for thousands
of years. Early societies such as the Native American Anasazis and the ancient Greeks perfected designs that effectively
exploited these natural processes. The Greeks considered anyone who didn't use passive solar to heat a home to
be a barbarian! In the United States, passive solar architecture experienced a major resurgence of interest in
the 1970s in response to crippling oil embargoes. With grand enthusiasm but with scant knowledge (and sometimes
little common sense), architects and builders created a wide variety of solar homes. Some worked pretty well, but
looked more like laboratories than houses. Others performed poorly, overheating in the summer because of excessive
or misplaced windows and skylights, and growing chilly in the colder months because of insufficient thermal mass
and insulation and poor siting. In The Solar House, Dan Chiras sets the record straight on the vast potential for
passive heating and cooling. Acknowledging the good intentions of misguided solar designers in the past, he highlights
certain egregious--and entirely avoidable--errors. More importantly, Chiras explains in methodical detail how today's
home builders can succeed with solar designs. Now that energy efficiency measures including higher levels of insulation
and multi-layered glazing have become standard, it is easier than ever before to create a comfortable and affordable
passive solar house that will provide year-round comfort in any climate. Moreover, since modern building materials
and airtight construction methods sometimes result in air-quality and even toxicity problems, Chiras explains state-of-the-art
ventilation and filtering techniques that complement the ancient solar strategies of thermal mass and daylighting.
Chiras also explains the new diagnostic aids available in printed worksheet or software formats, allowing readers
to generate their own design schemes.
