Greenbuild 2017 is Here! Visit Mitsubishi Electric in Booth 838

Greenbuild_resized

This week, the Mitsubishi Electric team is in Boston for the Greenbuild International Conference and Expo. Greenbuild is the world’s largest conference that brings together industry leaders, experts and professionals that specialize in sustainable building.

This year will include more participants than usual as Greenbuild and the ArchitectureBoston Expo (ABX) are co-locating at the Boston Convention & Exhibition Center (BCEC). Between the two shows, 25,000 people are anticipated to attend, with over 800 exhibitors.

Net zero building technology is expected to be one of the most popular topics at the conference. Parts of the exhibit hall will use onsite power generated by the Greenbuild Net Zero Zone and Microgrid Showcase. This showcase provides a unique opportunity to highlight sustainable technologies and products designed for the net zero building market, which is predicted to grow into a multi-billion-dollar market in the next few years.

If you are at the show, stop by booth #838 to learn about energy-efficient HVAC innovations from Mitsubishi Electric. We are proud to offer both residential and commercial products that minimize energy consumption while giving our customers maximum comfort and control over their environment.

Chattanooga Gets a Net-zero Home

Source: green|spaces

Last year, we told you how our M-Series systems were featured in the winning design at the NextGen Homes Design Competition. The purpose of the competition was to push the Chattanooga, Tennessee, region’s boundaries by designing, building and offering four homes with net-zero capabilities. The winning design achieved net-zero by pairing our energy-efficient systems with a 9 kW solar photovoltaic array on each home’s roof.

When we last wrote, construction was just beginning. Now, one of the homes is completed and on the market. The house is truly the first of its kind in the area, and we’re honored to have our technology contribute to its sustainability and healthfulness.

Within the next year, all four homes will be completed. We look forward to seeing how this next generation of houses fares – and we’ll keep you updated. Something tells us it will be very inspiring!

The Truth About Buzzwords

Talking with homeowners about our products often means using words like “sustainable,” “net-zero” and “green.” But should these words come up? Do homeowners respond well to them?

These are the exact questions the Shelton Group set out to answer in a recent study of over 2,000 U.S. respondents. The resultant report, “The Buzz on Buzzwords,” sheds light on the market’s perceptions of 11 words relating to “green.”

The results are surprising in places, and should influence how certain conversations occur with homeowners. It is helpful to know, for example, that 76 percent of respondents believe the word “green” indicates a steep price. Likewise that only 30 percent of respondents know what “net-zero” means, and an ample 43 percent believe it is an undesirable quality.

Just as technology shifts and progresses, so does the language we use to discuss it. Keeping current is a challenge, especially since it is now apparent that listeners might not fully grasp what we think of as everyday terms. Educating homeowners seems more important than ever before.

Project Profile: Full Plane Passive House


Homeowner Lisa Whitridge aimed high on the sustainability scale when planning her new 1,950-square-foot home. The Portland, Oregon, house complies with Passive House standards that focus on an airtight building envelope to achieve a 90 percent reduction in space heating and an overall 60 to 70 percent energy reduction. The house also meets the more rigorous Living Building Challenge by achieving net zero energy, waste and water.

A sailing enthusiast, Whitridge calls her new Passive House “Full Plane,” which means skimming over the water at high-speed under full sail, using natural energies from the wind.

Builder James Ray Arnold, JRA Green Building, Portland, called this a “dream Passive House project” because of its ideal location on a south-facing slope and meticulous, airtight construction that provides a low cooling and heating load.

But the home’s unique structure posed an HVAC dilemma. “The complicated framing in this house makes creating ductwork space within the walls almost impossible. We could not have made this installation without Mitsubishi Electric’s great ductless engineering,” Arnold said.

JRA Green Building worked with Imagine Energy, Portland, to specify and install a Mitsubishi Electric ductless system with an INVERTER-driven compressor and two 9,000-Btu ductless indoor units – one on each floor.

David Landau, project manager at Imagine Energy, says our ductless systems are the company’s go-to system for Passive Houses. “You get very high efficiencies for low loads, and the units are variable-speed and adapt well to the environment. The SEER ratings are as good as or better than the other products with INVERTER technology and the ductless system is nice because we need only a small amount of space to move the energy from the outdoor unit to the wall-mounted heads,” he says.

Net Zero Breaks New Ground with First Retrofit

Forbes, a leading business and finance news outlet, is exploring high-efficiency building. In a June 5 article, “Building The Capacity to Increase Net Zero Construction,” energy contributor Peter Kelly-Detwiler takes a deep dive into the growing phenomenon of net zero buildings.August 13_Net Zero Image 2

While the concept – buildings that produce as much or more energy than they consume – is well-known, net zero is often associated solely with new constructions. But as Kelly-Detwiler points out, “since less than one percent of the U.S. building stock gets added each year, the focus on rehabs is critical if the net zero movement is to gain any significant traction in the U.S.”

The article chronicles the development of the first retrofit to be recognized by the U.S. Department of Energy as meeting the requirements for net zero. Not only does the Zero Net Energy (ZNE) Center, San Leandro, Calif., pave the way for other energy-efficient rehabs, it is a space designed as a “learning hub for trainees in net zero and sustainable energy programs.”

August 13_Net Zero Image 1The designers of the ZNE Center (pictured left) tackled the net zero design process with a two-pronged approach. First, they focused on consumption, addressing energy efficiency with products and practices that would reduce energy use. Second, a renewable power was added to achieve a “grid neutral,” or zero net energy status.

Effective space conditioning is a critical part of reducing energy consumption and an area that Kelly-Detwiler addresses throughout the article. The ZNE Center uses VRF zoning systems, which are “smart enough to take heat from an overheated room and move it to where it is needed.”
