The 2020 National Green Building Standard (NGBS) includes some significant revisions from previous versions. One of the most significant is the scope expansion that allows the NGBS to be used for the design and construction of both the residential and non-residential space in mixed-use buildings. Prior to the 2020 NGBS, only the residential portion of mixed-use buildings could seek NGBS Green certification — the non-residential portion was either not included, or was forced to seek certification from another program.

We often hear speculation that because NGBS Green is the most widely used green building certification for residentially-used buildings, it must be the easiest and least rigorous to attain. Clearly, the individuals making those speculations have not taken the time to dig in and understand why NGBS Green is the most popular program. Below is my take on why NGBS Green is the leading green certification program – spoiler alert: it has nothing to do with being less rigorous. In fact, NGBS compliance may be the most difficult of all the green building certification programs when measuring the expected performance of the buildings being certified.

While the markets for new homes and building materials roil with unpredictability, there are some things in the new home construction industry that are a little more stable—such as the types of building lots available. “They’re not making any more land,” the old adage goes, and land for new residential developments is universally reported to be in extremely short supply.

Climate change and its effects are accelerating. Consequently, communities are suffering from more frequent and higher intensity climate-related disasters – from hurricanes to wildfires to flooding. With each new event, we have an opportunity to reconsider how we repair and rebuild disaster-damaged homes and how we design and build new homes.
Enhanced resilience is an essential part of any comprehensive green building certification. A green building standard like the National Green Building Standard ICC-700 (NGBS) is designed to eliminate or reduce the environmental impacts of the homes we build (or rebuild), and also includes practices to help homes better withstand future disasters.

This month we celebrate another NGBS Green milestone with the certification of our 250,000th NGBS Green Home. When we started the NGBS Green certification program in 2009, our goal was to provide a national, credible, rigorous, and affordable green building certification for the residential construction industry. Until NGBS Green started, residential building certifications lagged significantly behind other building types. The places we lived – our homes, townhouses, multifamily buildings, housing for students and seniors, and assisted living facilities – were foregoing high-performance green building programs because they were too difficult and expensive to attain. We had the audacity to believe that needed to change – and understood the role we could play in helping our entire industry do better. Better for the environment. Better for climate change. Better for homebuyers and renters.

With the 2020 NGBS, single-family homes can earn the NGBS Green Certified level if they comply with all applicable green practices from the 2020 NGBS Chapter 12. This streamlined yet rigorous certification path requires homes to be designed and constructed to be more efficient than 2018 IECC code-compliant homes and to include important building practices that ensure the home provides a healthier indoor environment, is more water efficient, and is more durable. The NGBS Chapter 12 Certified Path focuses on the most impactful practices that improve energy and water efficiency, create a healthier living space, and manage potential moisture issues. For energy efficiency, builders have a choice among Prescriptive, Performance, and Energy Rating Index (ERI) paths. For water efficiency, builders have a choice between Prescriptive and Performance paths. This certification option is more streamlined and, to keep verification costs lower, NGBS Green Verifiers can batch multiple homes for both registration and verification report submittal. Find out more about this option.

Energy-efficient home builders report that their homes sell faster, for more money, and perhaps more importantly, that their buyers are more satisfied with their energy-efficient home than with their former inefficient homes. Win-win-win. Builders are rewarded for their energy-efficient homes, the environment benefits from homes that require fewer nonrenewable resources, and homebuyers get a more high-performing home. But, is an energy-efficient home the golden ticket for builders? Unfortunately, no. Energy codes are becoming more stringent, so now, depending on a home’s location, even code-minimum homes can be relatively energy efficient. That makes energy performance less of a distinction among builders. Now may be the perfect time to consider emphasizing the health & wellness features of your green homes over their energy efficiency.

When first approved by ANSI in 2009, the NGBS was notable because it was the first national green building rating system specifically designed for residential buildings. Before the NGBS, national programs such as LEED and Green Globes were designed to address the specifics of commercial buildings. Consequently, only a few multifamily buildings in the pre-NGBS days tried to adapt to the compliance requirements of the early green certification options. But even the first few iterations of the NGBS did not cover all types of residential construction. The 2020 NGBS Consensus Committee sought to remedy this issue by revising the NGBS’s definition of residential. Now the NGBS is inclusive of all buildings within which we live during the various stages and phases of our lives. Find out more about the new opportunities now available to multifamily and mixed-use builders and developers.

Today, it can seem impossible to find a new appliance that isn’t a “smart” product. I recently purchased a new washer and dryer set, and I noted so many models with mobile and voice notification and control. Some products even featured automatic reordering of detergents and softeners based on sensor feedback!

Prior to COVID-19, a tightening labor supply and hot housing market portended a bright future for offsite housing construction methods, such as panelization and modular. In the wake of coronavirus and rising availability of workers sidelined from other industries, at least one key driver of builders adopting offsite methods may have faded. Are builders less inclined to adopt offsite construction now? Or are there other factors making them more ready for the change? A recent survey aimed to find out the answer to these and other related questions.

In early 2020, ANSI approved the fourth version of the National Green Building Standard ICC-700 (NGBS) as an American National Standard. Now, builders and developers have a choice to seek NGBS Green certification based on either the 2015 NGBS or the 2020 NGBS. Which is the best version for your project and your market? Some may presume that compliance with the 2015 NGBS would be less challenging and/or less expensive to achieve compliance. But, don’t be so quick to dismiss the 2020 as a more beneficial option. The 2020 NGBS Consensus Committee made several important improvements that warrant strong consideration before embarking on your next green building project. Check out this post on some factors to consider as you make the decision.

A lot of attention has been given to offsite building solutions in recent years, and data show that it’s quickly making inroads in multifamily and commercial construction. Offsite construction has also been touted as a solution to the shortage of skilled construction labor that has hampered housing production in the past few years. Large single-family builders have told us repeatedly how difficult it has been to keep up with housing demand because they can’t get homes built fast enough – they attribute this to the tight schedules of subcontracted labor who can’t find enough skilled workers to keep up. NAHB reports that the average cycle time for building a single-family home has increased from 6 months to 7 in the past few years.

Homebuyers look for sustainable and efficient design, but they also bring their own values to the home search. Health is top of mind for consumers right now, and many buyers recognize the role that our homes play in keeping us healthy and safe. Since we’re all spending more time at home, some buyers look for the convenience afforded by smart home systems and accessible design. And, while there is so much uncertainty globally, some crave the security that is afforded by energy and water independence and resilient design.

The national news and trade press have regularly kept us up-to-date on the COVID-19 traffic boost in home improvement warehouse (HIW) stores, largely due to their visibility with retail locations across the country and publicly-traded stock, which makes information on their performance readily available.

Building products manufacturers, mills, and wood treatment facilities are keenly aware of the COVID-19 traffic boost in home improvement warehouse (HIW) stores, such as Home Depot, Menards, and Lowes. If they have a strong presence in those locations, these manufacturers are happy about that boost. But many who aren’t well established in HIW stores and are more dependent on lumber and building materials dealers are feeling like they’re missing an opportunity.

With most of the 2020 Builder Practices Reports now available, we’ve been anxiously reviewing each report for new trends in building products for new homes. In addition to our traditional line up of questions, the 2020 survey contained some new topics—for example, we added questions on air sealing methods for new homes.

The 1970’s was the greatest home building decade in U.S. history in terms of the total number of new homes built—nearly 18 million residences in that decade. Fueled by the Baby Boom generation’s need for housing, there was a rental housing boom in the early 70’s, followed by a very strong starter home market, and later as the Baby Boom generation continued to move through its life cycle, began buying move-up homes like they did starter homes a decade earlier.

For the past several years, Outdoor Living upgrades have been getting a lot more attention as homeowners seek to expand their living space from within the walls of the home to beyond those borders. Average new home size has shrunk in the past few years, but the expansion of outdoor living space has more than filled the gap the shrinking home has left.

Our 2020 Annual Consumer Practices Survey is complete, data compiled, and reports will be available starting this week. More than 110,000 U.S. and Canadian households participated this year and provided highly-detailed information on their remodeling activities and purchases from nearly 40 different product categories. This is an incredibly important data year as it establishes a pre-COVID-19 benchmark to measure against. The home flooring replacement market, for example, was anything but static in the preceding year.

Occasionally, unforeseen opportunities arise in the course of research where data can be analyzed for a purpose that was not originally intended. Collecting data from our 100,000-response Consumer Practices Survey (CPS) occurred from mid-February to mid-April 2020; this collection period spanned the period of time when we first began seeing COVID-19 as a serious threat in the Unites States and governments began restricting certain businesses and activities.

While in most states home construction has been considered “essential” in our COVID-19-restricted economy, that doesn’t mean that all things have been “business-as-usual.” Quite the contrary. Builders and contractors are reporting that social distancing measures and shut downs in other sectors of the economy have slowed sales, lengthened construction times, and reduced the reliability and flexibility of their workforce. As states begin allowing limited re-opening of more businesses, construction companies are focusing on how to handle a surge in demand. But will the building product industry, with its own COVID-19 curtailments, be able to sufficiently supply a robust rebound of the residential construction industry? And, just as importantly, what product mix will satisfy the needs of the new industry environment?

In theory, business disruptions, even one as unexpected and drastic as COVID-19, can spur innovation in an industry as companies adapt to overcome new challenges to their economic viability. However, reality often favors the opposite end of the spectrum, where companies opt to retrench, preserve cash, and focus on short-term, revenue-generating functions as they prepare for a potential protracted downturn. This tactic likely results in reallocating dollars away from R&D and market expansion efforts. And, since these activities are generally associated with a company’s innovativeness – and further, its long-term health and viability – the chasm between the theoretical benefits and harsh reality of major disruptions widens.

One of the hottest topics in the industry press prior to March of this year was the ongoing and growing shortage of skilled construction labor. The coverage reflected the perceptions of home builders across the country as they faced this daunting issue and its effects on their businesses. Over the past few weeks, however, with builder confidence about future sales dropping sharply in response to COVID-19, we felt it was time for us to re-assess the labor environment as a builder priority.

Moisture control and dehumidification are increasingly hot topics among residential builders and property managers in hot-humid climates. Home Innovation's Cindy Wasser recently spoke with a couple of our manufacturer partners with NGBS Green Certified Products to learn more about the industry trends they’re seeing, and the solutions their companies are implementing to ensure energy-efficient green homes maintain proper moisture and humidity.

Most researchers associate discrete choice methodologies with surveys where the objective is to measure the “What” of buyer preference. But in qualitative research, where exploration is a common objective, discrete choice methodology can be applied to better understand the “Why” of decision dynamics and to identify what tradeoffs buyers are making when choosing building products or services. Home Innovation offers clients this powerful way to explore decision making through discrete choice qualitative research.

The NGBS Green Certification program team is monitoring the ongoing situation affecting the nation and the globe with the coronavirus/COVID-19. We have put certain practices into place and provided guidance to our NGBS Green Verifiers (who are all independent contractors subject to their own business requirements) and other program partners, and will continue to update as best practices and guidance from the CDC dictate.

You know your product addresses the growing construction labor shortage, but your claims are falling on the deaf ears of skeptical potential buyers. They’ve heard that claim before and want someone to provide verification that it really works. Unfortunately, for manufacturers who have developed truly improved products, there are few standard test methods to empirically validate benefits like these.

Historically, one of the biggest challenges home builders have faced is keeping rainwater out of wood-framed walls. Earliest techniques included big roof overhangs to shelter walls from rainwater, lapping siding boards to push water away from walls, protecting the framing with moisture-resistant sheathing materials, and later, placing a water-resistant layer like asphalt felt beneath siding to protect wood elements from rot.
