Now,an energy-sufficient computerised house

Such homes could reduce overall energy consumption and harmful pollution,and save people's money on their monthly utility bills.

Researchers have developed a new typical-looking suburban house which can generate as much energy as it consumes.

The laboratory designed house,for a family of four incorporates energy-efficient construction and appliances,including energy-generating technologies.

Following an initial year-long experiment,the facility will be used to improve test methods for energy-efficient technologies and develop cost-effective design standards for energy-efficient homes.

Such homes could reduce overall energy consumption and harmful pollution,and save people’s money on their monthly utility bills,according to a statement.

The unique facility was unveiled by the US Commerce Department’s National Institute of Standards and Technology (NIST).

The two-story,four-bedroom,three-bath Net-Zero Energy Residential Test Facility incorporates energy-efficient construction and appliances,as well as solar water heating and solar photovoltaic systems.

“Results from this lab will show if net-zero home design and technologies are ready for a neighborhood near you,” said Under Secretary of Commerce for Standards and Technology and NIST Director Patrick Gallagher.

“It will also allow development of new design standards and test methods for emerging energy-efficient technologies and,we hope,speed their adoption,” he added.

For the first year of its operation,the house will be used to demonstrate net-zero energy usage.

NIST researchers will use computer software and mechanical controls to simulate the activities of a family of four living in an energy-efficient home.

No actual humans will be allowed to enter the house during this time so that researchers can monitor how the house performs,but lights will turn on and off at specified times,hot water and appliances will run-and small devices will emit

heat and humidity just as people would.

A solar photovoltaic system will generate electricity to power lights and appliances when weather permits,and excess energy will be sent back to the local utility grid by means of a smart electric meter.

The house will draw energy from the grid on days it cannot generate enough on its own,but over the course of a year it will produce enough to make up for that purchased energy,for a net-zero energy usage.
