Why Provide a Green Homeowner Manual?

By Home Innovation

Homes today are complex – they involve systems within systems, integrated technologies, and dozens of “pieces” or components that homeowners rely on every day. Each home component – including systems, appliances, finishes, and more – has its own make, model, serial number, user manual, warranty information, and more.

A homeowners’ manual is the key to maintaining and understanding all of these components. It is a compilation of information to help homeowners quickly and easily find the information to operate and maintain their homes properly. With green homes this is particularly important as the efficiency and effectiveness of all the various elements that make the home “green” are very interrelated and cannot be overlooked. Homeowner education and documentation via a homeowners’ manual is a requirement of home certification to the National Green Building Standard™ (NGBS), but beyond that, it’s just good business!

Responses from NAHB and Guild Quality’s recent survey, “Homeowner’s Perspective: The Value of a Green Home,” illustrated that homeowners would like more education from their builders. Owners of Green Certified homes specifically requested education to “understand how to operate and maximize the benefits of the green-related features in their home.” Taking adequate, timely care of a home is extremely beneficial in the long run and a homeowners’ manual helps homeowners – your clients – protect their most significant and important investment.

What Should a Homeowner Manual Include?

A homeowners’ manual is an easy way to guide your clients to useful product information, common maintenance solutions, and homeowner education. It should also provide general green living tips, resources, and additional information.

The NGBS includes Homeowner Education/Maintenance elements as a way to ensure that homeowners are able to maintain and enjoy the long-term benefits from their homes’ green features. For a home to be NGBS Green Certified, the homeowners/maintenance manual must include all the mandatory items and obtain enough optional points to meet the Chapter 10 point threshold.

Where to Start: Inventory Home Components

A good starting point for your homeowners’ manual is the inventory of all of the major components and systems of the home. Each appliance or feature comes with a copious amount of information: a manual (or two); identifying numbers for the product; warranty information; and information on how to properly care for each component.

Ideally, this type of information should all be well organized and easily accessible. Logical ways to organize it may be by room or by system type. A simple spreadsheet, table, or list which references the item and physical location within the home, brand/manufacturer name, model name and number, and serial number is the most basic format.

Examples of home components to include are:

  • HVAC filters
  • thermostat operation and programming
  • lighting controls
  • appliances and settings
  • water heater settings
  • fan controls

Targeted Resources

Provide the homeowner advice, guidance, and resources for home care and research. This may include tips on how to save money on repairs, utilities, and replacements and help to reduce the total cost of homeownership. The key in this section is to make the information practical, easy to find and use.

Home-Related Resources

Homeowners often need references or other resources to conduct their own maintenance and improvements within the home. They can look to their neighbors, friends, or colleagues for these things, or they can rely on information you’ve provided them – and brag about how helpful their builder is to their neighbors, friends, and colleagues! These resources may include a diagram of the safety valves and controls in the home, local service providers for maintenance and service, frost-protected shallow foundation maintenance (where applicable), and photo records of the home’s framing with utilities. Be sure to include your/your business’s contact information in this information.

Guide to Maintenance Solutions

A narrative explaining the importance of maintenance and operation in retaining the attributes of a green-built building is the starting point for maintenance information. Maintenance checklists provide a baseline for homeowners on when to perform various maintenance tasks, as well as provide a guideline for what tasks are DIY versus those that may require calling a professional. Checklists may be organized as seasonal or annual, and you can either us a publicly available template or one you create. Your company may have a maintenance handbook that would be appropriate to include in this section of the manual as well. Other information you want to include: humidity maintenance how to’s; instructions for inspecting the building for termite infestation; maintenance of rainwater diverting systems (gutters and downspouts); and stormwater management.

Green Options & Landscaping

The exterior of homes and the landscaping around them often provide many opportunities for “greening up” practices and products. Options include understanding common hazardous materials used around the home and instructions for proper handling and disposal; information on organic pest control, fertilizers, deicers, and cleaning products; and information on native and/or low-water landscape materials.

Assembly, Presentation & Education

The intent of a homeowners’ manual is to deliver useful and timely information to homeowners – that’s a constant. How this information is delivered is more variable. Information may be delivered in a hard-copy printed version or in some digital/online format. Either way, the information should be organized and categorized for quick and easy access.

Homeowner education is typically conducted upon the walk-through of the house and can be easily reinforced with use of a homeowners’ manual. Good education and a comprehensive homeowners’ manual may even reduce call-backs, especially concerning the most common homeowner questions and concerns. Remember, homeowner education is an invaluable opportunity for you to showcase the quality of the green or high-performance home you have built, and your level of customer service.

You may wish to provide education and training on additional items as well. Your homeowners’ manual will offer your clients a lasting reminder of the care with which you built and presented their home.

NGBS Keeps Builders on The Cutting Edge

By Home Innovation

It is a classic conversation in the home building industry, the moves as well rehearsed as the opening of a chess game between two champions. There is an obvious, logical path and arguments for both sides when it comes to the adoption of new technologies and codes and builders’ general resistance to change.

Every green home verifier I know has been asked by a builder, “How green could it really be to air seal my house to such a level that I have to bring in make-up air through mechanical ventilation? Why not just let the house ‘breathe’ naturally by not sealing it up so tight?” This question, and others like it generated by new technology and codes, is one of the best reasons to have an expert verify your home based on the practices of the National Green Building Standard (NGBS). If you were building homes under the NGBS, you would have been asking this question back in 2008, if not earlier. Now it’s 2014, the 2012 International Energy Conservation Code (IECC) is gaining ground and being accepted in many states, and these are no longer questions of “if” but “when” you will be required to meet a certain building leakage number. If you already addressed this issue back in ’08, you’ve nothing to fear. The most current version of the NGBS brings you to the cutting edge of the building industry in terms of new technologies and code changes, which are evolving the industry into something totally different then when we were kids.

That being said, there are codes that make sense, and codes that don’t. During my last conversation that started off with the above question, a builder reminded me of a building code in the 70’s which required plastic (poly) to be stapled over insulation before the installation of drywall. That was stupid; no wonder builders are cautious. But now the industry and its practitioners have evolved. Building technology and innovation has grown into a field of study all its own. Builders need a person whose entire job is to stay up on the changes; someone whose job it is to help decipher which changes are to be embraced and which are to be fought. That person is an accredited verifier.

As a green home building verifier and advocate for high-performance, efficient construction, many people assume I embrace all the changes in the building code that seem to ratchet up energy- and resource-efficiency, but I don’t. I only embrace those that make sense from a building science perspective! To use an example from the 2012 IECC, I don’t think the wholesale installation of hot water pipe insulation (HWPI) makes sense. In my area of the country, many builders use a parallel piping system – the type of system where the hub looks like a spider with red and blue legs sprouting from the sides. A parallel piping system saves about 33 percent energy use over traditional piping. Now, even if you forget the exponential increase in the cost of HWPI between traditional piping and a parallel piping system (which can be around $300), think of the logistics. The difference (besides cost) is putting a two-inch hole through walls, TJIs, and possibly an LVL, and putting nine or more two-inch holes through all the same places. My point is if HWPI is mandated the way it is currently written, builders are more likely to revert to a traditional piping system and lose the 33 percent energy savings in favor of HWPI, which saves less energy.

In cases like this, you need that person there arguing on your behalf for something that makes sense – like an exception in the code for parallel piping systems. Before the NGBS became prominent, there were very few builders in my area who even knew what a parallel piping system was. It’s all about staying on the cutting edge, being ahead of the pack. And enlisting the help of a trained, accredited verifier and a rating system like the NGBS can do just that.

Back to our original question – why seal the house then bring in make-up air? There are plenty of sound reasons:

  • Improved Punch Out: You want to reduce nail pops and drywall cracks? The best way to do that is to reduce air movement and temperature differentiation within the wall. I work with a builder whose punch out list at the one-year walk is very limited.
  • Improved Air Quality: Which would you rather be breathing, the air that seeped through all of the little cracks in the house or air that was brought in intentionally and filtered before use?
  • Energy Savings: The use of point source air allows for a heat recovery ventilator (HRV) or an energy recovery ventilator (ERV) to be installed, saving precious energy and nullifying the argument of wasting conditioned air through mechanical ventilation.
  • Cleanliness: What lives in the aforementioned cracks in the building envelope? Dust. Along with eliminating dust, the elimination of cob webs is another benefit of a well-sealed house. No self-respecting spider would make a web where there is no air flow – no chance of catching anything!

So here’s the bottom line (conveniently located at the bottom of my post!). Why certify under the NGBS? Being at the cutting edge of the innovation implementation curve allows you more time for adjusting to the evolution of our industry. To know what’s out there, to see it coming, and to adjust accordingly. A third-party expert armed with a consensus-based “roadmap” like the National Green Building Standard is necessary to help you navigate today’s building world.

Navigating The ‘Gray Zone’ in Green: Commercial-Grade Residential Construction

By Home Innovation

The application of the National Green Building Standard (NGBS) to multifamily construction has been very successful over the past few years with it being accepted as the green program of choice at near exponential rates. There are many factors that promote its success, including affordability, ease of understanding from a residential builder’s perspective, and less onerous time and documentation demands for builders than other rating systems. These same factors make some feel that it is not a serious certification process. However, the rigorous approach of the NGBS to meeting the various levels of certification and its requirements to meet minimum levels in each of the major construction/building categories can allay the fears of most skeptics.

As an accredited Home Innovation NGBS Green Verifier since the certification program started, I have had an opportunity to verify 41 single-family homes and 29 multifamily buildings accounting for 740 apartments. In addition to new construction, I have also had considerable experience verifying green land development and renovations of existing buildings using the NGBS. All NGBS Green Verifiers are trained by Home Innovation to verify all types of green projects eligible for NGBS certification, but on-the-ground expertise in different verification types varies from verifier to verifier.

During a recent job site visit to conduct my initial team meeting and make introductions, it quickly became apparent that the level of code controlling this particular multifamily project fell under commercial construction guidelines. The questions being asked by the architect, engineer, and the mechanical, electrical, and plumbing (MEP) contractors made me realize how important it was to have the benefit of many years of experience working in both the residential and commercial construction industry.

Transitioning from multifamily low- and mid-rise buildings to multifamily high-rise buildings, it is important that your NGBS Green Verifier has experience in commercial-level construction and codes. Without this kind of experience, a verifier can be placed in a role that taxes the extent of his/her knowledge, thus requiring extra time, effort, and cost to understand the situation and research the proper interpretation. For example, construction tasks that are normally relegated to a subcontractor for smaller, garden-style projects are more typically handled by the larger nationally-oriented engineering and architectural firms for high-rise projects. Verifiers for these types of buildings are sometimes even called on to train the various subs for the project on green requirements and criteria of the NGBS. Also, ASHRAE 91.1-2007 plays a larger role in the energy and building envelope; the energy analysis for high-rise multifamily buildings is more complex. Even the building materials themselves become less familiar – high-rise buildings present a very different landscape of steel, concrete, and glass, as opposed to the wood, brick, and vinyl that are so familiar in single-family and smaller multifamily projects. You can see where there is a specialization for this type of verification work.

The housing market has seen trends towards higher-end, all-inclusive communities as multifamily living becomes the preferred residential lifestyle for many generations. With that trend increasing, more residential building will include commercial features, be located in urban areas, and be considered a high-rise structure. The NGBS scope clearly encompasses high-rise residential structures, but the proper application of certain practices is not explicit in the practice. It is therefore critical to understand the intent of the rules within the NGBS in order to provide an effective verification process for this sector of the industry. An NGBS Green Verifier’s role in confirming a building’s compliance with the NGBS is critical to the developer. However, because of the unique questions that arise with high-rise buildings, I also believe that involving an NGBS Green Verifier with appropriate high-rise/multifamily experience can offer valuable guidance and expertise that the developer’s entire project team will find useful from the beginning of the design process.

I am pleased to have been selected to serve on the ANSI Consensus Committee charged with development of the 2015 version of the NGBS, assigned to the Multifamily Task Group. I served previously on the ANSI Committee that developed the current 2012 version of the NGBS. I look forward to working with my peers on the Committee and the Task Groups to improve the sustainability practices and clarity of the NGBS, especially with regard to high-rise multifamily construction, to ensure the NGBS continues to be an affordable, yet rigorous, green building standard for all residential development.

Real Estate’s Market Value Shows Minimal Growth in Q2 2019

By Housing, Uncategorized

The recently released Federal Reserve’s Z.1 Financial Accounts of the United States report (formerly known as the Flow of Funds report) shows the latest transactions in households’ balance sheets as they occurred in the second quarter of 2019. The growth in the market values of homes in the U.S. grew less proportionately to the growth in mortgages taken on them than in previous quarters, i.e., households’ liabilities grew more than their assets. Thus, for the first time since the first quarter of 2012, owners’ equity in real estate as a percentage of household real estate declined, from 64.3% to 64.2%. On a non-seasonally adjusted basis, the market value of homes in the U.S. totaled $29.1 trillion and their mortgages totaled $10.4 trillion, leaving net equity at $18.7 trillion.

The above figure shows the plateauing of total real estate’s market value in the most recent quarter of data. As noted above, this is the first time since the first quarter of 2012 that the net owners’ equity as a percentage of household real estate declined. The first quarter of 2012 was also the trough of household’s assets’ market values following the Great Recession.

Gains for Top Builder Share

By Housing

The top 20 builders produced 29.0% of all the homes constructed in the country in 2018, according to data from BUILDER magazine. That share is a notable gain from 2017, when the largest 20 builders were responsible for 26.8% of all completions.

Historical data shows a rising trend in the market share of the top 20 builders[1].  In 2000, these businesses built 16.6% of homes completed.  By 2005, the share was 22.1%.  The impact of the Great Recession drove the share down to 21.0% by 2008, but it bounced back in the following years, surpassing 25% for the first time in 2013.

Large builders have grown by both entering new markets and expanding their operations in existing markets. An important component of this growth strategy has been the acquisitions of smaller firms and their land.  The recent purchase of American West by Pulte is an example of this phenomenon. Large builders have also been able to leverage their size to access credit markets to acquire land and to achieve economies of scale in the purchase of building materials.

Nonetheless, local and regional builders continue to be responsible for the majority of the homes constructed in the nation.

[1] The exact composition of the top 20 builders has varied over the years, so this analysis is based on the 20 builders with the largest number of closings in any given year and not on a fixed set of builders.

Examining Rental Housing Spatial Distribution

By Housing

With disruption to home construction from the Great Recession and more recently, declining affordability of homeownership, the number of renters in the US has expanded, reaching 109 million in 2017 or 34 percent of the population (up from 89 million and 30 percent in 2007).

As renting becomes more common, it is important to examine the types of rental structures people live in and their spatial distribution. Using the 2017 American Community Survey (ACS), this post explores the distribution of renter-occupied housing in the U.S.

Detached Rental Housing

After the recession, demand for detached rental homes rose significantly. In fact, detached renter-occupied housing accounted for 40 percent of all rental stock added between 2007 and 2017, more than any other structure type.

Concentrations of detached rental housing are scattered throughout the country, but many metro areas in the Southeast as well as the West have higher concentrations (Figure 1). Of the 10 metro areas with the highest concentrations, five are in California – Merced (59.7%), Visalia-Porterville (53.8%), Modesto (53.2%), Stockton-Lodi (52.4%) and Bakersfield (51.7%). These five metro areas also had some of the highest foreclosure rates at the height of the downturn, indicating an association between areas with high foreclosure rates and detached rental units.

ACS data also show that metro areas with higher concentrations of detached rental units are negatively associated with family income, indicating that detached rentals are more common in areas with lower-income families who cannot afford to buy a home, but are looking for more space than what a typical rental apartment would typically provide.

 

Attached Rental Housing

Attached renter-occupied units (townhouses) are a small share of the rental stock (6.4 percent in 2017) and accounted for 10 percent of rental stock growth between 2007 and 2017 (2.1 million to 2.7 million units). They do, however, make up a large share of the new construction rental segment: single-family built-for-rent (SFBFR) homes.

Attached rentals are concentrated in metro areas in the Mid-Atlantic region (Figure 2). The metro areas with the largest concentrations are Lebanon, PA (28.4%), Philadelphia (27.7%) and Baltimore (27.1%). The southeast coastal areas and the west coast have moderate concentrations of attached rental units.

Attached units are more common in areas with land constraints. Behind New England, the Mid-Atlantic region has the most expensive lot prices, indicating a shortage of lots. Research also shows that Millennials want to live in medium-density, walkable developments. Going forward, areas with higher shares of millennials may see growth in this structure type.

 

Large Rental Housing (Buildings with 50 plus units)

Renter-occupied units in buildings with 50+ units make up 12.6 percent of the rental stock and accounted for 21 percent of the rental stock growth between 2007 and 2017, second only to detached renter-occupied units.

Like detached rentals, the concentration of 50+ unit rental structures are relatively dispersed throughout the country (Figure 3). However, the concentration of 50+ unit rental structures reaches 20 percent in only six metro areas – Minneapolis (29%), New York (28.5%), Washington, DC (28%), San Jose (22.8%), Honolulu (21%), and Seattle (20.9%). With the exception of Honolulu, these metro areas have large populations, with at least 2 million inhabitants.

50+ renter-occupied units are most concentrated in metro areas with large urban centers and renter populations.  These areas tend to have lot shortages, but possess zoning for high-density construction.

 

Manufactured Rental Housing

The manufactured housing share of the rental stock is small at 4.4 percent, and grew by 7 percent between 2007 and 2017. Going forward this segment may grow at a faster pace given ongoing housing affordability challenges.

Manufactured rental housing is concentrated in metro areas in the Southeast and the Southwest regions (Figure 4). The Midwest, Northeast and the coastal west regions have lower concentrations.

Manufactured rental housing is more concentrated in metro areas with lower incomes, many of which are in the South. It provides an affordable option for households who cannot afford to rent single-family structures or to own. Research also shows that demand for manufactured housing is growing among retirees, as it provides a low-cost option for this submarket. This may be why manufactured housing shares are higher in states such as Arizona and New Mexico.
