  18. NATURAL HOME DESIGN TECHNIQUES (FOR LIVING, HEALTH AND ECONOMICS) DESIGN FACTORS • ENERGY TRANSFER AND HEAT EXPLANATION • GENERAL • Heat moves from warmer to cooler • RADIANT HEAT • Heat from the Sun or an electric radiator is Radiant Heat • Radiant transfers through the Air & absorbs onto surfaces it falls on. • Surfaces have different capacities to absorb (or reflect) heat. Dark surfaces absorb; light surfaces reflect. • All objects radiate heat in all directions • Warmer ones have more heat to exchange with cooler until it balances out. • Uncontrolled Radiant Heat is cause of discomfort; temperature reads OK but feel overheated. • In reverse, if surfaces not insulated then a large loss of Radiant Heat. Natural Home / Passive Solar Design ANZA VALLEY ARCHITECT

  19. NATURAL HOME DESIGN TECHNIQUES (FOR LIVING, HEALTH AND ECONOMICS) DESIGN FACTORS • ENERGY TRANSFER AND HEAT EXPLANATION • CONVECTION HEAT • Air heats, expands, is lighter and rises. • When passing over cooler objects it gives off some of its heat, cools, contracts and falls. • Faster air movement speeds up the Heat Exchange. • However, if air is trapped in spaces of porous objects & pockets, the air does not change. This is the basis of insulation. • CONDUCTION • Heat transferred from molecule to molecule in a solid material & from one material to an adjacent material. • Metals are very conductive, wood less, gases even lower. Natural Home / Passive Solar Design ANZA VALLEY ARCHITECT

  20. NATURAL HOME DESIGN TECHNIQUES (FOR LIVING, HEALTH AND ECONOMICS) DESIGN FACTORS • ENERGY TRANSFER AND HEAT EXPLANATION • SUMMARY • Heat Movement is calculated in the following Formula • RADIANT HEAT + CONVECTION + CONDUCTION = TOTAL • The total is measured in R Value which measures Thermal Resistance, and in U Value which measures Heat Transfer. U Value is the coefficient of R Value. Natural Home / Passive Solar Design These are the same principles forming the origins of Mechanical Systems/AC Systems designs / systems and equipment. It is applied to the house as the Mechanical Unit itself. ANZA VALLEY ARCHITECT

  21. NATURAL HOME DESIGN TECHNIQUES (FOR LIVING, HEALTH AND ECONOMICS) DESIGN FACTORS MICRO-CLIMATES Understanding the Micro-Climate is essential to proper design. Natural Home / Passive Solar Design ANZA VALLEY ARCHITECT

  22. NATURAL HOME DESIGN TECHNIQUES (FOR LIVING, HEALTH AND ECONOMICS) SOLAR HOME The Sun & Earth Relationship is the basis of the Solar Home. It is the same relationship with the Sun. Natural Home / Passive Solar Design Heat Radiates Heat Retained near Surface by Atmosphere, Land & Water Winds and Water Currents Circulate Heat ANZA VALLEY ARCHITECT

  23. NATURAL HOME DESIGN TECHNIQUES (FOR LIVING, HEALTH AND ECONOMICS) SOLAR HOME • PASSIVE SOLAR • Sun heats Spaces directly • Liquid stores Heat better than Solids Natural Home / Passive Solar Design • ACTIVE SOLAR • Utilize Solar Panels for PV or Water Heating • MAIN SOLAR SYSTEMS • Solar Windows such as Windows, Skylights & Storefront. • South facing glass & can add Light Scoops & Clerestory for North rooms. • Solar Walls such as Trombe’, Masonry, Stone, along with Glass Layer, Air Space & Fans as required to circulate. • Sunspaces such as Greenhouses, Verandas & Glazed Areas on South. • Active Systems such as Solar Panels. ANZA VALLEY ARCHITECT

  24. NATURAL HOME DESIGN TECHNIQUES (FOR LIVING, HEALTH AND ECONOMICS) EARTH INSULATED HOME • HISTORICAL PRECEDENCE • First Homes in Caves • Structures built into Ground or Hillsides, and/or Structures designed for Earth on Roof for Centuries in Many Areas of the World Natural Home / Passive Solar Design • THERMAL PROPERTIES • Earth is a natural Heat Moderator • Below frost line, Earth remains at a constant temperature of 55 degrees F • Even between surface and frost line Earth is the best performing insulation. ANZA VALLEY ARCHITECT

  25. NATURAL HOME DESIGN TECHNIQUES (FOR LIVING, HEALTH AND ECONOMICS) EARTH INSULATED HOMES Natural Home / Passive Solar Design LOCAL ANZA VALLEY EXAMPLE (Not by AVA) The Cave *ChilliAinsworth ANZA VALLEY ARCHITECT

  26. NATURAL HOME DESIGN TECHNIQUES (FOR LIVING, HEALTH AND ECONOMICS) EARTH INSULATED HOME • TIME LAG FACTOR CALLED “THERMAL FLYWHEEL” • Soil Heat Transfer Diagram Natural Home / Passive Solar Design • This process allows homes to function with almost no need for additional heating or cooling, meaning minimal use of conventional modern air conditioning methods, utilizing fossil fuels. ANZA VALLEY ARCHITECT

  27. NATURAL HOME DESIGN TECHNIQUES (FOR LIVING, HEALTH AND ECONOMICS) COOL HOME for Hot Climate • HOT (& HUMID) CLIMATE NEEDS • Lower Air Temperature • Speed up Air movement • Make surfaces cooler • Reduce Humidity Natural Home / Passive Solar Design • SHADING THE STRUCTURE • (Block/Reflect Sun Radiation) • Trees, Shrubs, Creepers, Earth cover all block Solar gain. • Long Overhangs, Awnings, Shutters, Screens, Shade Cloth, Pergolas, Trellises, Verandas, Low Emission Glass, Sails • Reflect radiation with light colors in roof & wall colors ANZA VALLEY ARCHITECT

  28. NATURAL HOME DESIGN TECHNIQUES (FOR LIVING, HEALTH AND ECONOMICS) COOL HOME for Hot Climate • SHADING • FORM & LAYOUT AFFECTS COOLING • Example: Courtyard Design • (Courtyard Plants & Water add Humidity as well) • SUMMER • Thick outer Walls & Roof keep spaces cool and Sun hits the courtyard for short time. • Convection Currents keep cool air pockets in smaller rooms. • As courtyard heats up, the cool air is drawn from the rooms to the courtyard, creating cooling breeze effect. • At night, heat from the courtyard roofs, stone floors cause reverse convection, drawing heated air to the back rooms. Also sleeping is accommodated in or near the courtyard. • WINTER • Reverse process, and heat is left in rooms by shuttering windows and openings to retain the heat. Natural Home / Passive Solar Design ANZA VALLEY ARCHITECT

  29. NATURAL HOME DESIGN TECHNIQUES (FOR LIVING, HEALTH AND ECONOMICS) COOL HOME for Hot Climate • SHADING • FORM & LAYOUT AFFECTS COOLING • Example: Courtyard Design • (Courtyard Plants & Water add Humidity as well) Natural Home / Passive Solar Design ANZA VALLEY ARCHITECT

  30. NATURAL HOME DESIGN TECHNIQUES (FOR LIVING, HEALTH AND ECONOMICS) COOL HOME for Hot Climate • VENTILATION • GENERAL • Increasing air movement helps evaporation from the skin & makes one feel fresher and active. • Hot regions generally have winds to help cool the areas and building. • When designing vent locations, air to enter low (cool air) and exit high (heated air). • Have air pass over water in dry climate; water in bowls and/or pools, and through vegetation. Natural Home / Passive Solar Design ANZA VALLEY ARCHITECT

  31. NATURAL HOME DESIGN TECHNIQUES (FOR LIVING, HEALTH AND ECONOMICS) COOL HOME for Hot Climate • VENTILATION • Wind Scoop Idea to Generate Winds • Wind scoops grab upper cooler winds at roof level. Air is sucked down to lower floor rooms, which pushes the heated air out (This is assured by high pressure at the windward side, and low pressure on the leeward side. • Window screens or lattice also used to reduce direct Sunlight. Natural Home / Passive Solar Design ANZA VALLEY ARCHITECT

  32. NATURAL HOME DESIGN TECHNIQUES (FOR LIVING, HEALTH AND ECONOMICS) COOL HOME for Hot Climate • THERMAL STACK EFFECT • Induces Ventilation & Cooling • Works like convection with passive solar heating elements in place, like sunspaces and solar windows. • Passive Solar when Heating, the space is radiated. • Passive Solar when Cooling, is the reverse. The Heat is allowed out at the top of the space, and the Cold Air is drawn from below. • Thermal Mass materials keep the process working. • The example home in the poster is this process. The central stair has open treads to allow the “chimney” effect allowing the air to work per the rules. The mass is the concrete slabs at the bottom level.

  34. NATURAL HOME DESIGN TECHNIQUES (FOR LIVING, HEALTH AND ECONOMICS) COOL HOME for Hot Climate • RADIANT COOLING • Induces Cooling with Greenhouse Space • The greenhouse space thermal mass elements are cooled at night. • Windows are opened to absorb the cool air at night. • During the day, as the Heat rises in the space, vents at upper levels are opened to remove the Heat. • This also induces the cooler air flow with opening lower vents or windows, pulling the cool air through the home to the greenhouse space. • The case study home is intending to use this process. The greenhouse space will work with water mass, concrete, tile or stone elements, and pull cool air from the north shaded deck and under-building cooler air.
