   A passivesolar home means a comfortable home that gets at least part of its heating, cooling, and lighting energy from the sun.
• 4.
   It isdesigned to use the energy of sun. It’s material and building works together to create energy.  LARGE WINDOWS SOLID WALL WATER FANS OVERHANGS.

   Large windowexpansion that allows sun energy, it faced south, made improvements in more low cost.  It is a construction material which stores or collect energy from sun.  Once power of the sun is collected, it should not be waste. So, it eliminates the air leak around the building.  Helps to circulate the stored solar energy when needed.

  Independent from futurefuel cost, save money long after initial cost recovery. High owner satisfaction and resale value. Reduced operation and repair. No operating noise, act as warmer and cooler according to the climate even in power failure .

   Passive solardesign save energy by maximizing the homes natural heating.  Passive solar building design very important role in reducing the greenhouse emissions in our society.  Creating passive solar building to save energy & which voluntary comply with openings are also important compliments to passive heating & cooling.

   Passive solarbuilding design…These standards are much higher then houses built to most normal building.  About 15% space heating in an ordinary home comes from solar energy passive solar houses are designed to let heat into the building during the winter…simple huge difference in comfort  The building it self server as solar collector & storage device where as ordinary building not like that.

  It uses thebasic design to trap heat when needed. So, it keep the house cool in summer and hot in winter. It picks up lot of free heat in winter from sunlight contains about a kW of heat .

   Active solartechnologies are employed to converts into solar energy another more useful form of energy.  This would normally be a conversion to heat or electrical energy.  Active solar uses electrical or mechanical equipment for this conversion.  Passive solar relies on the inherent thermo-dynamic properties of the system or materials to operate.  They do not need external energy source.

   An energy-plus-houseproduces more energy from renewable energy sources, over the course of a year, than it imports from external sources.  This is achieved using a combination of micro generation technology and low-energy building techniques, such as: passive solar building design and careful site selection and placement.  A reduction of modern conveniences can also contribute to energy savings, however many energy-plus houses are almost indistinguishable from a traditional home, preferring instead to use highly energy-efficient appliances, fixtures, etc., throughout the house

   A zero-energybuilding(ZEB) or net energy (ZNE) building general term applied a building with zero net energy (ZNE) consumption and zero carbon emission annually.  Reduce carbon emissions and reduce dependence on fossil fuels  zero energy buildings remain uncommon even in developed countries, they are gaining importance and popularity.

   No ZEBregulations or standards  Existing Energy Conservation Program  Existing Green Building Label System

  =  “First efficiency, thensolar”  Together, they can make a big difference.  = Zero Energy Building.

  Buildings are theLargest Energy Consumer in the U.S. 40% of primary energy, 72% of electricity, 55% of natural gas.

   Money Savings(>$1,000s/year)  Greater comfort.  Better quality of life, more free time, more money.  Less use, Less maintenance.  Longer lasting heating and cooling equipment.

   In theUnited States, buildings account for almost 40% of primary energy use and greenhouse gas emissions.  Energy use will help address climate change and extend the life of our national resources.  Has set a goal to achieve cost-effective, net-zero energy commercial buildings in all U.S. climate zones by .  Renewable Energy Laboratory (NREL) leads the way in net-zero energy building (NZEB) innovation.

  Can achieve zeroenergy home now  Design for efficiency and solar up-front.  Super high level of energy efficiency.  Encourage conservation of residents.  Choose solar thermal for water and pool heating.  Use small PV systems of 4kW or so this is still not cost effective at present electric rates without subsidies  Consider some PV on West side to reduce utility peak.  Watch your meter spin backwards

   This housewill save a projected $165,000 in fuel and energy cost.  Over the next 20 years.

   We aresaw about how to save energy.  In this way we are follow to reduce usage of electricity.  It will be help us and also our Future generation.
