LEED (Leadership in Energy and Environmental Design) homes are green homes, and they are transforming the residential market and people’s lives around the world. LEED homes are built to be healthier and safer by providing cleaner indoor air. They use less energy and water, leading to monthly savings on utilities, and maintain their value over time. More than 370,105 residential units have earned LEED certification as of October 2017, and both certified single-family homes and multi-family projects are selling faster and for more money than comparable, conventional homes.

“Since 2005, the green share of new single family residential construction has grown dramatically—increasing from 2 percent in 2005 to 23 percent in 2013. This 23 percent market share equates to a $36 billion market opportunity,” according to a study on green labels in the California housing market.

Green homes create value

  • Nationwide, the typical household spends about $2,150 on residential energy bills each year, but LEED-certified homes are designed to use about 30 to 60 percent less energy. Over the seven or eight years the typical family lives in a home, this adds up to thousands of dollars in savings. Levels of indoor air pollutants can often be four to five times higher than outdoor levels, and with people spending an average of 90 percent of their time indoors, the average American suffers from significant exposure to unhealthy indoor environments. LEED residential units provide significant value to consumers through dramatically improving upon these environmental health factors.
  • Green homes are built to be energy-efficient, ensuring that they can be comfortably heated and cooled with minimal energy usage. They are individually tested to minimize envelope and ductwork leakage and designed to minimize indoor and outdoor water usage.
  • Green homes are increasingly desirable. More than half of consumers rank green and energy-efficiency as top requirements for their next homes, and LEED certification is a top individual attribute of apartment rentals, second only to location near a central business district.
  • Green homes can be built for the same cost as—and sometimes less than—conventional homes. Average upfront costs of 2.4 percent are quickly recouped, as a homeowner will save money for the duration of his or her green home’s lifespan.
  • Green homes sell at higher prices and faster than comparable, conventional homes. According to a 2016 report, “What Is Green Worth? Unveiling High-Performance Home Premiums in Washington, D.C.," by real estate appraiser and author Sandra K. Adomatis and the Institute for Market Transformation, high-performing single family and multi-family homes with green features in Washington, D.C. will sell for 3.5 percent more than those without green features.

Green homes are growing

  • It is estimated that by 2018, the green, single-family housing market will represent about 40 percent of the market, and 84 percent of all residential construction will have sustainable features.
  • More than 370,105 residential units have earned LEED certification as of July 2017 around the world, and this number continues to rise in countries like the United States., Canada, Saudi Arabia and China. Within the United States, states with the most LEED-certified homes include California, Texas, New York, New Jersey and Georgia.
  • The 2015 Green Building Economic Impact Study, released by USGBC and prepared by Booz Allen Hamilton, found that the residential green construction market is expected to grow from $55 million in 2015 to $100.4 million in 2018, representing a year-over-year growth of 24.5 percent.

From lawn mowers to power tools, summer is the season for noisy equipment. There is certainly a lot to consider when you begin home improvements, but how often do you think about protecting your hearing?

You may assume the ringing sensation in your ears after using loud equipment is just an annoyance that will fade with time, but that is not always the case. Not only is it an indication you have come into contact with dangerous noise levels, it could also be a condition that lasts much longer than a minute or two.

Loud noise has the ability to harm your eardrum or your ear’s hair cells, which can lead to noise-induced hearing loss and/or constant tinnitus. Tinnitus is the perception of a ringing or buzzing sound even when the sound is not actually present. This can be permanent or temporary, but there is no known cure.

Hearing loss or tinnitus can occur after exposure to noise above 85 decibels, and the sound made by common tools often exceeds this. Many tools reach about 90 to 115 decibels, which can cause damage in a short amount of time. Even using a loud power tool for a few minutes without hearing protection could leave you with permanent hearing damage.

It is always good practice to wear hearing protection when using most tools. Even if they are not high-powered devices, they can easily reach above 85 decibels. Luckily, hearing protection is easy to find and won’t break your budget. Disposable foam earplugs are inexpensive and can be found at most pharmacies and hardware stores. For more heavy-duty protection, you can use silicone earplugs or noise-canceling earmuffs. These devices vary in the amount of noise they reduce, so make sure you are using ones appropriate for your needs.

Keep your ears safe and pick up some hearing protection next time you make a trip to the hardware store. Your ears will thank you!

LEED (Leadership in Energy and Environmental Design) has become the world’s most recognized rating system for green buildings. The LEED for Homes rating system was created in 2008 as a way for single-family homes and multi-family buildings to achieve LEED certification. LEED for Homes projects undergo a technically rigorous process to become certified, including multiple on-site inspections and diagnostic tests. Quality control and quality assurance are built into the process so that builders, architects and homeowners can rest assured they get what they paid for and specified. More than 1.2 million residential units are currently participating in LEED. USGBC’s recent Green Building Economic Impact Study found that the residential green construction market is expected to grow from $55 million in 2015 to $100.4 million in 2018, representing a year-over-year growth of 24.5 percent.

Tips about responsible household practices

What is a home energy audit, and what does it usually cost? A variety of approaches, price points and follow-up actions may be chosen. Here is an overview of what to expect when choosing the right audit for your needs.

1) How much does an audit cost?

  • Free audits are often available from utility companies. They usually consist of an energy survey by a third-party professional who visits many homes and can identify common problems. You can also get a free audit from a contractor or supplier from an HVAC, window or lighting company, for example. These professionals may be more likely to make a sales pitch for their product, but if you have already identified a particular area to make an improvement, going with a specific contractor may be helpful.
  • Audits for problems that are more difficult to diagnose may run $300 to $1,500. In a scenario where you need an expert to provide more thorough diagnostic testing, energy modeling and assistance with determining the best installation choices, you can expect to pay more. However, if you think you may need to make a major investment in upgrading your home's energy efficiency, it could be the lower-cost solution in the long run.

2) What does the audit involve?

  • An energy survey usually takes about an hour and consists of a brief interview with the occupants of the home, a walk-through and completion of a checklist. The auditor will then give recommendations for improvements, based on the results of the survey.
  • In contrast, a comprehensive home energy audit combines a survey with additional diagnostics, such as home and duct tightness testing, utility bill analysis and energy modeling. The energy model can show you the baseline of where you are starting from and then quantify the improvement you would likely see from implementing different measures.

3) Who performs the audit?

  • A consultant is trained in building science and can perform the energy audit, give advice, help you choose contractors and then test to make sure that the work was properly completed. These consultants are often HERS raters. A consultant may be less biased than a contractor in making recommendations.
  • Contractors have the same training as consultants, but can also perform the improvement work itself with their own crews (or act as the general contractor and supervise the work). Such contractors may also be known as "building analysts" and some deliver what is known as Home Performance with Energy Star, a DOE/EPA program. A contractor may provide faster estimates and follow-up for implementation.
  • A combined approach is also possible through organizations or partnerships that offer both consulting and implementation.

4) Choosing an auditor

Whatever route you take, look for an experienced auditor who has a certification, such as HERS Rater, HERS Auditor or Building Performance Analyst. Awards from BPI, Resnet or major trade organizations are also a good sign, as is a positive Better Business Bureau rating.

While LEED-certified homes have some common characteristics, the rest is up to your imagination.

"Doing my part to contribute to sustainable development is all well and good, but what will my house look like?" This is often the secret (or not so secret) thought running through the minds of many homebuyers and builders considering a LEED-certified home. How can you balance environmental responsibility with your tastes in architectural style and your desires for the house of your dreams?

Fortunately, the market for environmental building products is growing rapidly. This is happening as consumers become more aware of the collective ecological impact of the building industry, and as the many rating systems, environmental laws and certification programs, such as LEED, help push the market down the path to sustainability.

So what does a LEED-certified home look like architecturally? And how does it compare with what a sustainable house should look like? 

Photo credit: Natural Balance Home Builders, original photo on Houzz

That latter question is what sometimes launches LEED into a controversial whirlwind, which I will now try to sum up for you in a very basic way: 

A LEED-certified home, as you’re about to see from the photos in this article, can pretty much look like anything you want. The strength (and weakness) of the LEED for Homes rating system is that it attempts to reconcile sustainable building objectives with the current reality of the green building market and the range of options that are realistically available to the majority of people.  

This means that some LEED-certified homes will offer the best of environmental features, respect local and traditional building techniques, maintain small and compact forms that are easier to heat and cool, and push the envelope in innovative sustainable construction methods. 

Meanwhile, others may be the result of a calculated attempt to gain the minimum credits for certification while maintaining floor plans and luxury amenities to compete with other high-end options.

The range between the two can be quite large, hence the controversy. 

The best course of action as a prospective homeowner is to understand the background of this controversy so that you can make more informed decisions about a specific LEED-certified home. 

Here are some key visual clues to help you understand what you're likely to see in a LEED home and with a sustainable home in general:

Size: How big can my LEED home be?

Ideally, an ecologically responsible home is small and compact in form. Small houses consume less energy and require fewer resources to build. Fewer irregularities in the form mean fewer opportunities for thermal bridges, which are points in the building’s envelope or skin that make it easy for heat to escape in winter and enter in summer. To keep costs down for construction, heating and cooling, a small, compact footprint usually exhibits the best conservation practices. 

Still, you will find many LEED homes with massively luxurious floor plans. Here we find ourselves at the heart of one of the LEED controversies: Some people believe that allowing a home over a certain size to pursue certification is hypocritical if the message is supposed to be about conservation. 

The flip side to that argument is that someone who wants to build a big house will probably do so anyway. If that big house is LEED-certified, many aspects of it will help reduce its impact. While some view this as too small of a step, others point out that at least it's a step in the right direction.

Setting (rural): Can my LEED home be in the countryside?

Another visual clue for understanding the look of a LEED home is its relationship with its site.

A rural home that is well integrated with its site can respond to the local natural environment and even contribute to the area's biodiversity and ecology. By using resources already in the future building footprint (for example, using excavated dirt for rammed earth walls, as in this Caterpillar House) and by employing landscaping techniques such as xeriscaping (the elimination of irrigation needs), the impact of the building can be minimal and the site can serve as an extension of the natural surroundings.

Setting (urban): Can my LEED home be on an urban infill lot?

Similarly, in an urban setting, the strengths of the natural surroundings take the form of existing infrastructure. Is the house close to local transportation and public parks? Does the lot use building volume while providing open space, perhaps a roof deck or green roof? Urban LEED-certified houses often take in many of these considerations in an attempt to promote the development of infill sites while mitigating what's called the "heat island effect." 

This phenomenon is the reason the temperature downtown is always a bit higher than outside the city. When buildings, streets and sidewalks are packed together, the combined effect of all of that asphalt and dark colored roof material can be an “island” of warmer temperatures. The LEED rating system rewards homes that use permeable paving systems, shading and other strategies to help mitigate that effect.

Orientation: Will my LEED home need to face a certain direction?


Photo credit: Kipnis Architecture + Planning, original photo on Houzz

Along the same lines, one thing you may notice about a LEED-certified home is that it will be oriented to take advantage of passive solar heat gains in the winter and shaded from the heat of the summer sun. This is a fundamental concept in designing any building that claims to consume less energy. 

Tip: When looking at a house to possibly purchase, take a compass with you to see how well the house is oriented relative to the path of the sun. Several smartphone applications can help you track the sun’s path at a given location.

Materials and methods: Do I have to use certain materials in my LEED home?

A home design that responds appropriately to local building traditions and available materials can be another visual indicator of a LEED home and an environmentally responsible building.

Vernacular (domestic or functional) architecture of a specific region plays an important role in design considerations. But it doesn't mean that your LEED home must be in the architectural style of the region you live in. 

Sometimes local building methods and materials can be used in new ways while still reaping the benefits of being cost-effective and geographically appropriate.

High-quality construction details: Why does my LEED home design need to be so detailed and specific?

A truly sustainable home requires durability and attention to construction details. We want this house to have a long, healthy life, so the details are extremely important. For example, it's not just the design of the wall section, or even just the selection of a specific kind of insulation; it's also how that insulation is installed and how well it is tested and verified. 

One of the reoccurring arguments in favor of the LEED rating system (as well as many other voluntary third party certifications) is that it provides a framework for this quality control check. It provides a prescribed path for builders to take, keeping them accountable to their original objectives. And it gives the clients an extra set of verifications on the construction site.
