Grade I insulation is a common term used widely by building professionals; however, how Grade I is defined varies considerably among building professionals. At its core, the term is meant to construe that the home’s insulation is installed properly and will be as effective as possible based on the properties of the material. Learn how to achieve proper Grade I insulation based on NGBS Green requirements.

Two weeks ago, I blogged about a summary of findings to a builder survey, where more than 250 write-in responses to the question, “What are your biggest challenges in constructing homes to meet current energy codes?” were received.
Responses varied widely. In an attempt to summarize the breadth of responses, I would say they indicated that building more energy-efficient homes means the home building industry has to change, and change can be painful — particularly painful when the industry is producing at near capacity, labor and materials costs are rising, and both management and jobsite labor are in short supply. The 85% of respondents who indicated having challenges seemed to convey that the fast pace of building code changes is disrupting the design and construction of homes, and they are trying to sort things out.

In December 2018, Home Innovations Research Labs fielded our Omnibus Survey of 300 U.S. home builders, which included dozens of questions from sponsoring manufacturers. We also included some of our own questions to gain insight into current building construction issues.

It’s been about 30 years since Home Innovation Research Labs built the first Smart House prototype in Maryland research home park. The whole “smart home” concept has been on the verge of exploding in the market for decades, but along the way changing homes, demographics, technologies, and lifestyles have continued to evolve and caused wrinkles in the plans of companies and organizations bringing this technology to market.

The data is in! Home Innovation’s 2018 Builder Practices Survey continues to reveal many new trends and reversals. Some of the most notable changes we’ve seen so far have been highlighted in my recent Trends posts. Here are a few more points I’ve found interesting during my ongoing analysis…

One of the most important aspects of multifamily construction is scheduling. If done properly, it can save the owner and the
general contractor a lot of time, money, and frustration. But all too often, this process is not monitored closely enough. In large multi-million-dollar projects,
the smallest mistakes in construction sequencing can be devastating to
the project by causing costly delays, damages, and legal actions. NGBS Green Verifiers can help you plan so that a small error in scheduling doesn't result in a major catastrophe in your green building.

Despite green building experts’ declarations to the contrary, a truly high-performance, green home is not always easy for builders to design and construct, and there are always additional costs involved as compared to building a code-minimum home. These are facts. But we do all that we can to make the process easier and more affordable for builders, so that more builders will build green homes and verify performance with independent, third-party verification.

Homebuyers want much more out of their homes than just energy efficiency. The research findings proving this point are irrefutable. Yet there are still builders who put all their marketing might onto the single-point message that their homes are energy efficient and will provide a tangible, monetary payback. That's leaving a lot of unclaimed marketing chips on the table for the home features buyers value even more than energy and the related cost savings. Isn't it time to face the facts and deliver what homebuyers really want? Homes that provide a healthy place for their families, comfort, and contribute to a sustainable lifestyle — truly green homes.

With model building codes ramping up thermal envelope requirements for homes, and homebuyers becoming increasingly concerned (and knowledgeable) about managing their energy bills, both builders and buyers are scrutinizing the performance of the insulative products used in their homes. R-value is the most obvious and universal “proof point” that batt insulation will perform as expected, but how confident can you be that the R-value posted on a label actually reflects how that product will perform? Very confident … as long as the product also carries our Lab Certified mark.

It's 2014, the 2012 International Energy Conservation Code (IECC) is gaining ground and being accepted in many states, and it is no longer a question of "if" but "when" you will be required to meet a certain building leakage number. So if you're a home builder still asking, “Isn't it better – and greener – to just let my homes 'breathe' naturally rather than sealing them tightly and relying on mechanical ventilation?” you're in for an abrupt and rude awakening when the new code comes to town. Don't wait. The future is now. And certification to the NGBS is your best tool.

At Elevate Energy, we design and implement efficiency programs that lower costs, protect the environment, and ensure the benefits of energy efficiency reach those who need them most. As a provider of these programs, we understand that future success is dependent upon energy efficiency becoming transparent in the real estate transaction of high performance homes.

High-performance homes appeal to consumers because of their touted benefits: a healthier indoor environment, lower operating costs, and increased durability. Certainly, the benefits are compelling. But do we know if high-performance homes can live up to these elevated expectations?

The next generation of housing industry professionals has to be better trained to deliver the home of the future. The DOE Challenge Home Student Design Competition is part of this important transformation process toward creating better homes and communities.

In mid-December, we closed out registration for the DOE Challenge Home Student Design Competition. The response we got from colleges and universities across North America was really inspiring — all told, 32 teams have stepped up to the challenge in DOE's "race to zero" in energy-efficient home designs. Find out more.

While cost is always a factor with home builders, we've seen through data collected in our Annual Builder Practices Survey that value is often an overriding consideration. See what we've found for how builders address the cost vs. value equation when increasing R-value in their new homes.

It's all relative. That adage certainly holds true when considering moisture content in wood-based building materials. A retrospective on what we've found over the last five years of our investigations on moisture performance of common wall assemblies, and a call for the next round.

The 2008 National Green Building Standard has been helping transform the residential construction industry since it was published in January 2009. With the ANSI approval this week of the 2012 version of the NGBS, I look forward to the even greater transformation to come.

Like many, a new year has me reflecting on past accomplishments, pondering new goals, and committing to a few new resolutions. Why not make a resolution that gives you the possibility of success and provides some extra joy – resolve to build a green certified home this year.

Visions of holiday savings at the mall may be dancing through the heads of consumers across the country this Thanksgiving weekend, but I've been thinking about percent energy savings instead. What can I say? I'm an energy code geek!

With thermal performance requirements being ratcheted up throughout the building code, it's more important than ever to get a true sense of how the building envelope performs as a system. The Home Innovation can help with our large-scale hot box.

What's lurking in those dark attics and creepy crawlspaces just in time for Halloween? Market opportunities, if you know what to look for. An Home Innovation Research Labs nationwide survey of builders earlier this month showed some interesting new trends in unvented attics and crawlspaces.
