AHRI vs. City of Albuquerque, a case that I first posted on in 2008, finally reached its conclusion last week.  In line with the preliminary injunction she ordered on October 3, 2008, Judge Maria Vazquez of the District of New Mexico decided that Albuquerque’s energy code was preempted by Federal law mandating the energy efficiency of HVAC (more…)

When it’s hot in the summer, we want our air conditioners blasting to keep us cool. And when winter brings shorter days and freezing temperatures, we want the heat and lights full on. Until spring – and daylight savings time – arrives. We don’t want to waste precious resources, but we do want to be comfortable! (more…)

Once a building or facility manager has an ENERGY STAR statement of energy performance in hand they’re ready to set goals for improvements that will raise their rating but are often faced with no budget and minimal management support. The key to turning that situation around is showing how common best practices that cost little or provide quick payback can create both (more…)

As most parents are giddily aware of, this week marks the annual migration back to school for children and teens across the US and Canada. For the next ten months, kids will be ensconced in their daily routines, busy learning how to grow up to become mostly coherent, socially acceptable adults. Parents left with a delightfully quiet house during the day are not the only ones (more…)

As restaurateurs struggle to keep their business afloat with fewer customers, some are turning to greening as a way to stand out from competitors, from serving local foods to making deliveries in hybrid electric vehicles. When greening includes energy-saving strategies, the benefits can increase profits in addition to helping the environment. (more…)

Hallowell International in Bangor, Maine, is the manufacturer of the Acadia, a combined heating and cooling system that can be combined with solar or wind installations to take users off the grid. The system can be installed in new buildings or can be retrofitted when consumers are considering green upgrades.

CleanTechies has three questions for president and founder Duane Hallowell.

CleanTechies: Acadia uses something called “boosted compression” technology. Tell us about that.

Duane Hallowell: Since the 1950s, heat pumps, which operate by exchanging air for heating and cooling, have been the most popular and environmentally-friendly heating ventilation and cooling (HVAC) application. However, because they absorb heat from the outside air, they are inefficient in cold-weather climates, requiring additional, costly heating elements in order to work correctly.

There are plenty of companies and individuals that are cashing in on the green building market proliferation, but how is a designer, contractor, or home buyer supposed to decipher the information and separate greenwashing from legitimacy? Unquestionably, there is no shortage of information on the subject – right or wrong. Unfortunately, there are very few adequate resources that have mainstream appeal and effectively represent the sustainability movement from the various perspectives of all of the individuals that need to be involved.

I came up with this long list of rhetorical questions. My intention is to illustrate the disconnect that seems to be prevalent among industry professionals, design clients, the media, and the general public regarding sustainable building.

It is understandable why some utilities might be hesitant to embrace smart grid technology. It’s expensive (Repower America says implementation will cost upwards of $400 billion) and at the same time will reduce their ability to sell their core product (energy).

Getting the utilities and regulatory agencies on board requires ample amounts of carrots (financial incentives) and sticks (limiting carbon emissions), according to energy efficiency experts Portland Energy Conservation Inc (PECI).

PECI’s new report “Wiring the Smart Grid for Energy Efficiency goes into deeply depressing detail about the many formidable challenges to implementing the smart grid. Among the toughest to tackle are that buildings are ill-equipped to participate in demand response systems, and the near total lack of interoperability today between grid equipment and building energy management tools. There’s also a lack of university and professional training programs to fill the gaping hole in HVAC engineers who can maximize energy efficiency programs.
