Zero energy buildings built in hot

Zero Energy Project Almost 48 percent of energy in the U. Zero energy buildings drastically reduce that energy use by slashing the demand for energy, while supplying the remaining energy needs from renewable energy sources, such as solar panels.

Light bulb regulations, LEED and Energy Star ratings for homes and appliances, stricter construction codes, and government incentives are all parts of a national effort to cut energy waste in the building sector.

So a handful of builders are taking the idea one step further: Why construct a building that uses less energy when we can make one that uses no energy at all? By the purest definition, a net-zero building produces all the renewable energy it needs on site, drawing no more power from the grid than it gives back.

But advances in technology over the past decade have made it easier to design sophisticated buildings that produce percent of their own energy. At least 21 commercial buildings in the United States meet net-zero standards, according to a study released yesterday by the New Buildings Institute and the Zero Energy Commercial Building Consortium.

They run the gamut from offices to libraries to elementary schools. Researchers identified eight more unverified buildings that may also be net zero and an additional 39 that would classify if they installed more on-site renewable energy systems, plus dozens more under construction. Expanding the possibilities The first commercial-scale net-zero building was a center for environmental studies, completed at Oberlin College in Ohio in At that time, the project was largely an experiment in sustainable architecture.

Thanks to advances in structural insulation, energy-efficient appliances, new government incentives and the falling price of solar, expensive green-building projects -- like net zero -- are now within reach.

When Frank Walker first stepped inside a net-zero house in Denver two summers ago, he knew he wanted to trying building one himself. The design was so efficient, says Walker, that "you could heat the house using a hair dryer.

Inspired by what he saw, Walker decided to replicate the building. Having perfected its net-zero design, Oakwood plans to start marketing more of the homes in Colorado later this year. Each four-bedroom house will feature rooftop solar panels, a high-efficiency tankless water heater, super-insulated windows and airtight construction.

Each commercial and residential building employs a unique blend of renewable energy and architectural design to reach net zero, but there are some characteristics that nearly every structure shares.

Most use solar panels to achieve the bulk of their power and have numerous windows to minimize the need for artificial light.

Getting to Zero National Forum presentations are now available.

Tight insulation and low-energy appliances are also key elements. Paradoxically, most buildings actually receive electricity bills -- though not very many. This happens because a net-zero building may need to draw electricity from the grid to power its lights at night, for example, then returns that energy the next day, when its solar panels are most efficient.

Likewise, residents may have to pay for heating costs in the winter, but in the summer they would receive a check for their overflow of energy.New Buildings Institute, CPUC and utilities collaborated to host two southern California training on zero net energy trends, policy and funding opportunities, case studies, and tools for communicating and planning zero energy buildings.

Since , Natural Energy Applied Research and Zero Energy Design® have developed HUNDREDS OF NEAR-ZERO ENERGY HOME DESIGNS that have been built across the U.S., Canada, and Australia, in every type of climatic zone. Each one is uniquely designed for its site-specific and owner-budget / lifestyle objectives.
