PASSIVE SOLAR BUILDINGS



 A passive solar home means a comfortable home that gets at least part of its heating, cooling, and  lighting energy from the sun.



It is designed to use the energy of sun. It’s material  and building works together to create energy. energy.

Large window expansion that allows sun energy, energy, it faced fa ced 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 future fuel cost, save money long after initial cost recovery recovery.. High owner satisfaction and resale value. Reduced operation and repair. No operating noise, act as warmer  and cooler cooler accord according ing to to the clim climate ate even in power  power  failure .

Passive solar design 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 solar building 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.

uses the basic 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 sunli su nligh ghtt co cont ntai ains ns ab abou outt a kW kW of he heat at .

Active solar technologies

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 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 e n e r g y - p l u s - h o u s e  produces more energy from renewable energy sources, over the course of a year, 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 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

In the United 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.
