For Better Homes, Is it Net Zero or Passive House?

While solar homes have reached a milestone, superior envelope efficiency must be primary

U.S. Department of Energy (DOE) recently announced that the number of U.S. homes with solar panels has reached 1 million. As the primary on-site renewable power generation source, the expansion of rooftop solar photovoltaic (PV) means a much more distributed network of energy production and a more resilient energy grid.  But is the expansion of solar overshadowing basic tenets of optimizing energy efficiency?

Providence Homes on Selling Comfort

Research shows that consumers want energy efficiency, but they’re motivated by comfort. As builders pursue energy efficient homes, they may need to shift how they promote the benefits of high performance homes to potential buyers, so that their messages resonate on an emotional level in an area that consumers really care about: comfort.

5 Things Builders Can Do to Reduce Comfort Callbacks

Comfort callbacks are both timely and cost consuming, so here’s what you can do to reduce them.

The single largest financial investment that consumers will make in their lifetime is their home and a wealth of research finds that homeowners want their abodes to be energy efficient and comfortable.  Both comfort and energy efficiency rely heavily on the delivery of consistent, quality construction, yet despite builder efforts, that goal falls short at times, leading to problems with home comfort. What can builders do to reduce comfort callbacks?

Manufactured Housing to Get Energy Efficiency Boost

With a goal of reducing energy use while increasing efficiency and cutting carbon emissions, the U.S. Department of Energy (DOE) in June proposed the first new energy efficiency standards update for manufactured homes in more than 20 years. The changes would cumulatively cut energy use by an estimated 30 percent over a 30 year period compared to the current standard and include a focus on the thermal envelope/insulation as the foundation of energy efficiency.

What’s the ROI of Attic Insulation?

As fall approaches it’s time to consider options to weatherize your home. This means making improvements that can help improve comfort and lower energy bills, in the winter months and beyond. For homeowners trying to prioritize their home improvement dollars, and time, the question of what to focus on first often comes up. We’re going to make the case for attic insulation, as new data has come to light regarding its benefits.

“Trades may grumble but customers are lining up”

Addison Homes, a green builder in Greenville, South Carolina, certainly didn’t set out to cause trade partners to grumble, murmur or gripe. They set out to build DOE certified Zero Energy Ready Homes (ZERH) to provide their customers with the energy savings, comfort and indoor air quality such homes deliver. To do that, Addison Homes had to get local trades on board by doing things a bit differently. In doing so, they provided award-winning homes that customers rave about. They even show off the energy-efficient features included in the home (the homeowners in their winning Cobbler Lane project show their guests the pristine conditioned crawlspace…seriously).

New Guide Reveals What Builders Think of HERS Raters

HERS ratings are fast becoming a norm for residential new construction. In 2008, 100,000 homes received a HERS rating. In 2016, we passed the 100,000 market in just the first half of the year. The growth in HERS ratings has in turn elevated HERS raters into an increasingly important advisory role for many builders. More than just providing a score, raters frequently influence the specification and purchase of energy-related home products, train subs on proper installation, perform QA, troubleshoot and of course provide needed building science knowledge. All this begs one question: what do builders think about this new player in the space?

Lab Test vs. Eye Test: Slumping and Settling

Over the years, there has been significant discussion about batt insulation slumping and loose fill insulation settling. Manufacturers often discount these claims as inaccurate or the result of rumors spread by competitors. They do this because they have test data they believe proves these defects are not real issues. But the perspective of builders, HERS raters, insulation contractors and other boots on the ground is driven by what they see in the field, and that includes settled loose fill and slumped batts. How do we reconcile the lab test with the eye test?

A Custom Builder’s Approach to Economical, Energy Efficient Insulation

As both a green and custom home builder, Eddie Fort of PD & M Contractors has a client base that is affluent and knowledgeable about energy efficiency.  Fort, winner of the 2015 EarthCraft “Home of the Year,” award, builds shorefront properties in Smith Mountain Lake, Virginia, near the geographic center of the state and adjacent to Lynchburg.  At a price point of $750,000 and above, Eddie works closely with his clients to deliver a dream home that includes all the “bells and whistles” you expect with a custom home, which typically means “high end” everything. But for PD & M, delivering energy efficiency and quality doesn’t have to come at a super premium price. In fact, the company insists on spending its client’s money wisely. One area where they achieve that goal is through using hybrid insulation systems – particularly “flash and batt.”

Air Sealing “Like a Boss”

Insulation Institute has been focusing of late on the topic of air sealing and what it takes to construct a home that is airtight using the “3 Ps,”  — People, Practices and Products. Proper air sealing is critical for meeting stringent air change rates required for green building targets such as HERS, Energy Star, Net Zero or Passive House.  While there’s a plethora of guidance available on air sealing from many sources within the building industry, the best guidance to convey to the various contractors involved in home construction can be distilled to this: air seal “like a boss.” That is to say that everyone involved in the construction of that home has a role to play and their role should not be viewed as that of a “jobber” but a “boss” when it comes to air sealing, because getting to stringent targets requires that one think “holistically” versus individually.
