A recently completed project tested and proven combinations of passive and active energy efficiency technologies across different European climate zones.

Tools, techniques and resources have been developed to help navigate the latest in building know-how and businesses models, as well as understand continuous operation strategies and their costs.

Significant energy saving and CO2 emission gains have been achieved following applied research and real-world testing at two demonstration sites and one building simulation. A blend of active and passive solutions has been tested in different countries and with different end-uses. The result is a wealth of resources now available helps others implement targeted and cost effective retrofitting strategies using an appropriate mix of technologies.

Panasonic Develops Unique Vacuum Insulated Glass Based on Its Plasma Display Panel Technology

Posted by Green Builder Staff

Mar 5, 2018 4:55:33 PM

The vacuum insulated glass achieves the industry's top-class(*1) insulation performance for glass of approx. 6 mm total thickness.

Panasonic Corporation today announced it has developed and succeeded in mass production of thin, high-performance vacuum insulated glass by applying technologies the company accumulated in the development and manufacturing of plasma display panels (PDPs). The glass achieves a heat transfer coefficient (Ug value) of 0.7 (W/m²K)(*2), the industry's top-class(*1) insulation performance for glass with a total thickness of 6 mm, which is equal to or greater than triple glass containing argon gas(*3) with a total thickness of about 3 cm.

The Incredible Predictability of Building Moisture Problems

Suppose there was a tool that could predict the likelihood of whether your building would fail. What if this tool could also provide you with information to dramatically decrease risk factors?

At the risk of oversimplifying a complex process, we believe we have created such a tool. Our moisture prediction charts have been adapted from a mold and moisture manual Liberty Building Forensics Group (LBFG) developed for Disney Corporation in the early 1990s. Since then, they have been beta tested on literally thousands of hotels, and have proven repeatedly to be as true today as they were 20 years ago.

After spending almost six years consolidating separate parcels into a contiguous 634-acre tract of mature forest touching seven different lakes—and another four years negotiating a development agreement with the regional Canadian government—the Penney Group embarked on a unique challenge: creating an open-space conservation community restricted to only 634 moderately sized and priced residences, while leaving 60 percent of the pristine landscape undisturbed. It also needed to implement a septic system for the homes without risk of contaminating the lakes..

These housing design breakthroughs could be in all new homes in a few years.

One of the most important questions in construction is the open-ended, “Wouldn’t it be great if…?” This is usually followed by “That will never work” or “How could somebody actually make that happen?”

Airtight Home Pays Its Own Way in Energy Use

Posted by Green Builder Staff

Dec 20, 2017 3:14:57 PM

“Why aren’t zero-energy healthy homes the norm for new homes in our market?” The answer from builders: “Because people aren’t asking for them.” The answer from buyers: “Because builders aren’t building them, or I can’t afford the upgrades.”

Sustainable living advocate green|spaces sought to solve this problem by designing, developing and ultimately selling a series of spec-built net-zero-energy homes. In the process, the nonprofit educated the entire market, including designers, builders, real estate agents, appraisers, buyers, lenders, students and teachers. With simple, off-the-shelf features, the design team delivered a home that can produce as much energy as it consumes, protects and promotes the health of its occupants, and uses water and materials responsibly—all at a conventional price point for the neighborhood in which it is located.
