Keep Your Cool

A well designed solar house is both warm when you want it and cool when you want it; that is to say, the temperature tends to stay fairly even. Another good way to keep your cool is to dig into the earth. About six feet under the earth, you will find that the temperature varies by only a few degrees year round. While this temperature (about 50-55 degrees F.) might be too cool for general living comfort, you can use the stability of the earth's temperature to moderate the thermal fluctuations of the house. If you dig into a south-facing hillside to build, or berm the north part of the house with soil, you can take advantage of this. The part of the house that is underground needs to be well insulated, or the earth will continually suck warmth out of the house.

PSP

PSP refers to a method of building developed by Mike Oehler, who wrote The Fifty Dollar and Up Underground House Book. Mike definitely has some ideas worth relating, although they won't appeal to everyone. He did indeed build a fifty dollar house that he is still living in, although I believe he has added on a few hundred dollar wing to it. Much of the savings that Mike has been able to attain is through a combination of using recycled materials, logs harvested from his own land, and a simple method of building underground.

PSP stands for Post/Shoring/Polyethylene. The framework of the building is created with posts that are preserved in various ways and planted in the earth. These posts serve to support both the walls and the ceiling. The space between the posts is planked with used dimensional lumber, such as from wood pallets. This is what he calls the "shoring". Then the whole thing is wrapped in polyethylene plastic before it is backfilled with earth, making a truly underground home. Instead of conventional flooring, Mike advocates using the existing earth, finely raked and smoothed, and then carpeting thrown over it.

To me the most impressive aspect of what Mike has to offer is in his design concepts for building underground. He has come up with a system for designing rooms that can provide daylight and proper drainage for a wide variety of arrangements. His thinking goes way beyond what most underground architects have accomplished.

Passive Solar Architecture: Heating, Cooling, Ventilation, Daylighting and More Using Natural Flows by David Bainbridge and Ken Haggard, 2011. New buildings can be designed to be solar oriented, naturally heated and cooled, naturally lit and ventilated, and made with renewable, sustainable materials - no matter the location or climate. Bainbridge and Haggard draw upon examples from their own experiences, as well as those of others, of more than three decades to offer both overarching principles as well as the details and formulas needed to successfully design a more comfortable, healthy, and secure place in which to live, laugh, dance, and be comfortable. Even if the power goes off. Passive Solar Architecture also discusses "greener" and more-sustainable building materials and how to use them, and explores the historical roots of green design that have made possible buildings that produce more energy and other resources than they use. Fully illustrated with many diagrams and photographs, Passive Solar Architecture is an invaluable resource to anyone who wants to undertake a sustainable building project, from planning and design, to building, remodeling, and operating the completed building.

Earth-Sheltered Houses [Kindle Edition] by Natan Snider, There are many advantages to earth-sheltered construction. An earth-sheltered home is less susceptible to the impact of extreme outdoor air temperatures, so you won't feel the effects of adverse weather as much as in a conventional house. Temperatures inside the house are more stable than in conventional homes, and with less temperature variability, interior rooms seem more comfortable. Because earth covers part or all of their exterior, earth-sheltered houses require less outside maintenance, such as painting and cleaning gutters. Constructing a house that is dug into the earth or surrounded by earth builds in some natural soundproofing. Plans for most earth-sheltered houses "blend" the building into the landscape more harmoniously than a conventional home. Finally, earth-sheltered houses can cost less to insure because their design offers extra protection against high winds, hailstorms, and natural disasters such as tornados and hurricanes.

Earth sheltering: Burdei, Basement, Dugout (shelter), Ground-coupled heat exchanger, Earth house, Earthship, Green roof, Passive house, Passive solar, ... Underground living, Grubenhaus, Earth lodge by Frederic P. Miller, Agnes F. Vandome, John McBrewster, 2009. Earth sheltering is the architectural practice of using earth against building walls for external thermal mass, to reduce heat loss, and to easily maintain a steady indoor air temperature. Earth sheltering is popular in modern times among advocates of passive solar and sustainable architecture, but has been around for nearly as long as humans have been constructing their own shelter.

ClimateSkin: Building-skin Concepts that Can Do More with Less Energy by Gerhard Hausladen, Michael de Saldanha, and Petra Liedl, 2008. The facade plays a critical role in the conception of energy- and climate-optimized buildings: it is the building's skin and functions as an interface between interior and exterior space. It provides thermal and sound insulation and ventilation, and controls and guides the entrance of daylight into the building. Climate Skin offers concrete planning advice for architects and engineers who wish to exploit not only the architectural potential of facades but also their energy and climate-control possibilities, treating the building envelope as an essential component within a complete climate-control and technology solution. It provides a solid foundation of knowledge that equips the reader to make competent technical and economic evaluations of building envelopes. For everyone concerned with facades, Climate Skin is a comprehensive planning handbook and reference work that covers all of the relevant technical and physical aspects of the design and detailed planning of energy-efficient facades.

The Earth Sheltered Solar Greenhouse Book by Mike Oehler, 2007. The author writes, "my secret is that on the south wall of the greenhouse I dig a pit down eight feet and build a walkway up four or five feet where I can walk and bend over the growing beds to work on the plants. The pit allows cold winter air to flow downward to be heated by the earth rather than lying on the plants. On flat land I'd sink my north wall and all the grow areas about four foot deep and pile the earth up on the north side leaving at least a foot of north wall exposed for ventilation "windows" that can be opened as needed. I'd put some rigid foam insulation over that mound of earth on the north and a layer of polyethylene to keep it dry and some inches of earth to protect the poly from the sun. That north mound will serve as a heat sink then, to radiate heat back into the greenhouse at night." A complete review of this book by Kelly Hart can be read here.

The Earth-Sheltered House: An Architect's Sketchbook by Malcolm Wells, 2009. The author's perspective on design and the building process is based on millennia of use of earth-sheltered homes by animals and humans, using the earth to keep warm in winter and cool in summer. His imaginative architectural drawings, sketches, and design plans are surrounded by his handwritten commentary about Earth-friendly building and design, cryptic remarks and humorous asides that make this book a pleasure to browse or read. He offers a breathtaking assortment of some of the most creative and unusual home and building designs ever assembled. Some are fully underground structures, some partially earth-sheltered, but all make the best use of light sources, designed to benefit from the sun and seasonal changes, and to protect or restore the natural habitat around and above them. Wells's work is revolutionary, but readers will find his message to be pure common sense. Earth sheltering offers superior comfort with minimal energy input, and it is adaptable to diverse terrains as well as a variety of architectural aesthetics.

Earth-Sheltered Houses: How to Build an Affordable Underground House by Rob Roy, 2006. An earth-sheltered, earth-roofed home has the least impact upon the land of all housing styles, leaving almost zero footprint on the planet. Earth-Sheltered Houses is a practical guide for those who want to build their own underground home at moderate cost. It describes the benefits of sheltering a home with earth, including the added comfort and energy efficiency from the moderating influence of the earth on the home's temperature (keeping it warm in the winter and cool in the summer), along with the benefits of low maintenance and the protection against fire, sound, earthquake, and storm afforded by the earth. Extra benefits from adding an earth or other living roof option include greater longevity of the roof substrate, fine aesthetics, and environmental harmony. The book covers all of the various construction techniques involved, including details on planning, excavation, footings, floor, walls, framing, roofing, waterproofing, insulation, and drainage. Specific methods appropriate for the inexperienced owner/builder are a particular focus and include: pouring one's own footings and/or floor, the use of dry-stacked (surface-bonded) concrete block walls, post-and-beam framing, plank-and-beam roofing, drainage methods and self-adhesive waterproofing membranes.

Vertical Gardens by Anna Lambertini, 2007. Bringing nature into urban environments has always been a challenge; one of the most spectacular solutions to this problem is the vertical garden. Far more than just an unusual decoration attached to a wall, these gardens are an exciting means of bringing life and greenery to a bleak courtyard, a gray city street or a cold modern building. Vertical Gardens is the first publication to present a collection of the most important examples of this emerging trend. Those who create vertical gardens apply the principles of hydroponics and use ingenious framing systems that allow luxuriant compositions of plant life to colonize the exteriors of buildings. The aesthetic result is truly stunning and has attracted the attention of many architects and designers. Vertical Gardens explores this phenomenon in thematic sections, which are enriched by the reflections of its most innovative practitioners. This richly illustrated book will be essential reading for all professionals or anyone interested in this fertile new area of landscape design.

Underground Buildings: More Than Meets the Eye, by Loretta Hall, 2003. Unusual as they seem, underground buildings are surprisingly common. Every day, millions in North America work, shop, dine, study, and play in the more than three hundred public and commercial structures and five thousand private homes nestled in the earth. Underground buildings are safe, attractive, useful, and comfortable places to frequent and live. Unlike a common misconception, most are dry and warm, and they are often sun-filled. More than one hundred underground buildings are included in this fascinating subterranean tour. These buildings range from the famous to the unnoticed. Some were built for pragmatic reasons, others for aesthetic considerations, still others, for a combination of both. There are impressive success stories and discouraging tales of failure. Some underground buildings are incredibly energy-efficient, for example, while others leaked so badly they were abandoned. A vast spectrum of structures is presented, ranging from stunning examples of hidden opulence to humble subterranean cubbyholes where unassuming people immerse themselves in nature’s simplicity.

Heating or Cooling Your Building Naturally: Solar Architectural Solutions by Virginia B. Macdonald, 2006. Through an initial explanation of her principles and ten case studies, the author relates how vertical ventilation and controlled daylighting--to the exclusion of air-conditioning and daytime electric lighting--can be applied. The author explains in simple language, with photos and diagrams, how to use the sun to cool or warm a building as needed, while at the same time reducing mildew, dust, and many pathogens. The premise is simple and has been used throughout the ages in all cultures and climates: hot air rises. That's the starting point for all the ideas and designs contained in this book, taking advantage of the natural vertical flow of air to regulate the temperature of enclosed spaces. Likewise, the documented health benefits of controlled daylighting are well-known, and the projects here described make ample use of skylights (with spectrally-selective glazing) in addition to windows, so that electric lighting is seldom needed during the day.

Stay Cool: A Design Guide for the Built Environment in Hot Climates by Holger Koch-Nielsen, 2002. In hot dry or warm humid countries, more than half of the urban peak load of energy consumption is used to satisfy air-conditioning demands alone. Since the urbanization rate in developing countries is extreme, the pressure placed on energy resources to satisfy the future requirements of the built environment will be great, unless new, more cost-effective measures can be introduced. Stay Cool is an essential guide for planning and design using active design principles and passive means to satisfy human comfort requirements specifically in these climate zones, based on examples of traditional and modern constructions. The book demonstrates how a design strategy for urban environments and individual buildings, incorporating naturally occurring resources and specific energy-efficient technologies, can create a location, form and structure that promotes significant energy savings. Such strategies can equally be applied to low cost housing, or indeed to any other buildings, in order to improve comfort with passive means and low energy budgets.

PLANS

SunEarth House Paul Shippee, Designer

This earth-covered, passive solar, 1863 sq ft house achieved the very best performance in a HUD-sponsored energy survey when it was first built in the late 1970's. For three years after the house was built, it was computer-monitored, and according to the National Solar Data Network, the SunEarth house out-performed hundreds of passive solar houses in the country. The house was designed, built, and marketed by Colorado Sunworks. The furnace was put to rest during its first winter because the pilot light was wasting natural gas. All of the space heating demand is supplied by the passive solar system.

The heating system is a direct gain, passive solar system and drum wall. The south side exposes 300 square feet of glass windows. The windows are two panes of insulated glass that run floor to roof. Behind the windows are 54 large, vertically stacked barrels. Sunlight directly warms these 55-gallon oil drums that are painted with a flat black finish and filled with water. During the day, the water and interior concrete walls inside the house absorb the sun's heat. The heat is released slowly after the sun sets.

At night, when temperatures begin to drop, a blower pushes polystyrene beads between the two panes of glass, providing insulation to keep the daytime heat inside the home. On winter nights, this moveable Beadwall insulation converts the large window areas to R20 heat loss barrier. Six vertical skylights are arranged on the north side of the earth roof. Maximum solar energy takes place during the winter, and minimum solar energy occurs in the summer.

Winter Mode

Stored solar heat is released from the water containers as needed. Heat flows naturally by low temperature radiation and by warm air convection to the north side of the house, thus balancing comfort zones throughout the living space.

Summer Mode

Interior thermal mass is cooled down on summer nights by providing a natural air now path. Daily heat gains aree rejected by this method through turbine roof ventilators. The cooled massive house is then closed up on hot summer days for comfortable living.
