Builders aim for super-energy-efficient homes

Builders aim for super-energy-efficient homes | Développement durable et efficacité énergétique | Scoop.it

Crowned with three gables and painted in hues of gray and white, the suburban home in Lake Forest doesn't look much like the domicile of the future.

But as summer heat radiates off the fresh asphalt outside, the home runs comfortably at full tilt indoors. Recessed lights shine, radios blare and air-conditioned splendor greets hot skin. Despite all systems going, the property is producing more electricity than it can consume on a warm summer day — and that's the goal.

FirstFuel, inverse modeling and speeding up the U.S. utility energy efficiency mandate market.

“In the time it takes that entire lifecycle to happen for one building, we’re doing 100 buildings, identifying 100 times more opportunities, doing 100 times more engagements,” he said. While that’s not so important to individual building owners, it’s a big deal to a utility that has millions of commercial and industrial customers to sift through, looking for the best targets for efficiency gains.

We propose a new approach — which we call 'wedging the gap' — consisting of 21 coherent major initiatives that together would trigger greenhouse-gas emission reductions of around 10 gigatonnes of carbon dioxide equivalent (Gt CO2e) by 2020, plus the benefits of enhanced reductions in air-pollutant emissions.

CBO | Addressing Market Barriers to Energy Efficiency in Buildings

A large share of total U.S. energy consumption—40 percent—occurs in homes and buildings. Homes and buildings are less energy efficient than they would be if people could assess the value of energy savings more easily and correctly, and if energy prices provided them with stronger incentives to do so. This paper identifies three reasons why people undervalue energy savings: misperceived energy prices, imperfect information about energy efficiency, and biased reasoning about energy savings. The paper then examines four types of policy options for addressing those underlying market imperfections: prices that reflect the social costs of energy use, financial incentives, energy-efficiency standards, and better information about energy efficiency.

Due to risks associated with upgrade projects or the age of the building itself, cost savings aren't always maximized. Learn how to shift your risk while offering incentives to others.
