NATURE LIVINGSEA OF CORTEZ, MÉXICOThe proposed project for the first Prototype House in this sustainable development will use innovative advanced proven technologies to develop zero energy homes optimized for Baja California conditions. Prototype house design is based in the following concepts:-Energy-efficient building.-Renewable energy.-Passive Solar.-Auto sufficient & off-the-grid Hydraulic and Septic systems-Optimize material use.-On site recycle waste management.The project goal is to create efficient “zero energy homes” using only on-site power. Developing zero energy home technology will create opportunity for marketable products that exceeds the world energy and environmental standards.The design purpose of “zero energy homes” will be reached through the use of 3 systems which act together since the very initial phases of the project:I.- PASSIVE DESIGN SYSTEMSII.- BUILDING SYSTEMSIII.-MECHANICAL SYSTEMSI) PASSIVE DESIGN SYSTEMSA) – BASIC TECHNIQUE,Passive design uses two basic concepts:1) Preventing heat gain.2) Rejecting unwanted heat.1) The heat-gain control, is of far greater importance than is generally recognized.Factors involved include:1.Site Considerations.LocationOrientationVegetationLand massingMicroclimate modification2. Architectural FeaturesBuilding exposureSurface/volume ratioScreensShadesWing wallsOverhangs3. Building Component Feat.InsulationGlazingThermo massMaterial typeTextureFinishes2) The rejection of unwanted heat, can be divided into three major categories:1.Direct LossNatural ventilationInduced ventilations.Thermal chimney.2.Indirect LossRoof pondDouble roofEvaporative pondsEarth Integration3.Isolated LossCooling body of waterGround coolingCooling tubeCooling fieldCooling pondThese objectives of heat gain control and the rejection of unwanted heat are accomplished bythe following different methods:1.Shading from the sun2.Reflection of solar heat3.Insulation4.Ground cooling5.Wind cooling (natural breeze or inducedconvection)6.Water cooling7.Evaporative cooling8.Dehumidification9.Night radiant cooling10.Night cooling of thermal mass inbuildings11.Exotic passive cooling methods12.Seasonal cold storage13.Site Resources14.Orientation15.LocationII ) CONSTRUCTION SYSTEMSA -- SLABS--Light concrete slab-Design flexibility-Short time to complete the job.-Savings in the use of columns and beams.-Long spans available-Fire Resistant-Durable.-Maintenance-free-Energy efficient.-All-Season Construction-Economy and valueB -- WALLS--Building insulation system -Concrete panels poured in-site or pre-casted in a warehouse-Insulation system sandwiched between 2 layers of concrete-No-heat transmitting materials-Prevents mold, leaving humidity outside-Eliminates threat of termites and other pests that can attack insulation systems.-Proven under fireC – WINDOWS-- Sliding window systems-UV rays filter system, to protect flooring, furniture and art.-Insulated glass to avoid thermal transmission.-Laminated glass to resist hurricane impact.-Recycled aluminum frames-Ability to cover long openings.-Recycled glass window panels.III) MECHANICAL SYSTEMSA – HYDRAULIC SYSTEMS-Large amounts of fresh water produced from Seawater-Drinking potable water produced from Seawater.-Pure water straight from Seawater-Desalinization units for exterior operation2.- Residential septic system --2 anaerobic filter tanks-Contact aeration tank-Sedimentation tank-Disinfection tank-No steel post needed3.- Solar thermal power-System gathers energy radiated by the sun and converts it into useful heat inthe form of warm water.-Eliminates the use of fossil fuels-Powered by electricity generated by solar panels.-Used for domestic water heating as well for pool water heating.B – GEOTHERMAL ENERGY-The most energy-efficient conditioning system available.-Same system cools or heats the house depending on the season.-Environmentally clean and cost-effective.-Electricity used to move heat, not to produce it-5KW of heat produced by each KW of electricity used-Energy extracted from the ground. Clean, free and renewable.-Geothermal heat pumps take advantage of cool ground temperatures forcooling with high efficiencyC– SOLAR PANELS-Silent conversion of light into electrical energy.-No mobile parts, require minimal maintenance.-Designed to last for many years.-Panels work best in direct sunlight, but also work well even on cloudy days.-Affordable production of clean energy.
