Truth or Fiction?
Sustainable or greenwashed? It’s an easy claim to make and a harder one to live up to. As a Structural Insulated Panel (SIP) manufacturer, we’d rather you judge us on what’s actually behind ours, starting before your home or building is even built.
How Much Carbon Do SIPs Actually Save?
For an average 3,000-square-foot house in Virginia, building with SIPs eliminates roughly 10,326 lbs. of carbon emissions a year compared to stick-built construction, and more than 1,000,000 lbs. over its lifetime. It’s what happens when a home is built tighter and leaks less. Less energy burned every year means a lighter footprint for as long as your family calls it home. It’s the biggest carbon reduction you can make for the investment, whether you’re building where you’ll raise a family or where someone else will.
SINCE 2010, ACME Panel has helped build over 500 buildings with SIPs, preventing approximately 10,700 metric tons of carbon dioxide, equivalent to 215 cars taken off the road every year.
Why This Matters
Carbon numbers show up differently depending on who you are.
Building a home: it’s less carbon produced for as long as your family lives there, and the one after that. A quieter kind of legacy than most people think about when they picture “sustainable.”
Building for a client, or building your business: a certification or a completed project with real numbers gives your client something concrete to see.
The ACME Proof, Not the Promise
- 406 solar panels power our Radford, Virginia facility, generating 44,100 watts, more than 70% of everything our plant and offices run on. Every SIP that leaves here starts on clean energy, before it ever becomes part of somebody's home or building.
- We strip and recycle all the waste foam from manufacturing, instead of sending it to a landfill.
- Our SIPs contain much less embodied energy than other comparable products – this means the carbon footprint of concrete, metal, and other buildings damage our environment much more than a SIPs house will.
- We've worked with builders, architects, timber framers, and homeowners to design and build to standards like Energy Star, LEED, Net Zero, and Passive House
How SIPs Cut Carbon
SIPs reduce carbon in two places most people don’t think to look.
During construction: your walls and roof are cut to fit in our factory and show up ready to install. Less waste on the jobsite, and less energy burned to make the materials in the first place, compared to concrete or steel.
During the life of the building: a SIP home holds its temperature instead of leaking it out through the studs, the way stick-frame construction does. That’s why SIP homes commonly score below 50 on a HERS rating, using less than half the energy of a standard new build to heat and cool, year after year.
Less energy used, year after year, for decades. That’s where the real savings come from. It adds up.
Certifications & Third-Party Verification
Here’s how to verify it yourself, and what the major certifications actually mean.
HERS Rating. A Home Energy Rating System score measures how efficient a building actually is. Lower is better. SIP buildings commonly score below 50, meaning they use less than half the energy of a standard code-minimum new build to heat and cool.
Third-party certifications. ACME is a SIPA member, NTA quality-control audited, and holds ICC ESR-4524. Independent verification from organizations outside ACME.
Request the Life Cycle Analysis. A full LCA compares a product’s total environmental impact, from manufacturing through decades of use. Check the date on ours and ask us for a current one if it’s aged out.
Green building certifications, if you want one:
- Energy Star: rates appliances, windows, and materials. An Energy Star-rated building can cut overall energy output by up to 35%.
- LEED (USGBC): a points-based certification across site, water, energy, and materials, scalable from a single building to a whole neighborhood.
- National Green Building Standard: ANSI-certified, focused on site, resource, water, and energy efficiency, with separate tracks for remodels, single-family, and multi-family.
- Zero Energy Ready: a Department of Energy standard targeting roughly 45% less energy use than a standard new build, typically paired with solar.
- Passive House: focuses on an airtight envelope and solar positioning. Can achieve roughly 75% less energy use than a standard build.
- Net Zero: energy generated balances energy used. Net zero emissions (carbon neutral) goes a step further and offsets any remaining output.
- Living Building Challenge: the most rigorous standard. Buildings must operate as intended for a full year before certification.
You don’t need a certification to build better. These are simply ways to prove it, if you want one.
Frequently Asked Questions
What is Green Building?
Green building means reducing a building’s impact on the environment: less energy consumed, fewer raw materials used, a healthier indoor environment, and less water waste. SIPs address the first two directly. They use less energy to operate and fewer total materials to build than stick-frame construction.
What is a carbon footprint, and how do I measure a building's?
A building’s carbon footprint is the greenhouse gas output from the energy used to build, heat, and cool it over its lifetime. You can evaluate it through a Life Cycle Analysis (LCA), which compares total environmental impact from manufacturing through decades of operation, or more simply through a HERS score, which rates how efficiently the finished building performs.
How are SIPs eco-efficient?
An independent Life Cycle Analysis found that SIPs use significantly less energy during operation and fewer raw materials during construction than code-minimum buildings. Both translate directly into lower lifetime carbon output for the finished building.
Do I need my building certified to know it's green?
No. Certification (LEED, Energy Star, Passive House, etc.) is one way to verify performance, but it isn’t required to build efficiently. A REScheck, blower door test, or HERS rating after construction will tell you how your specific building performs, certified or not.
What has ACME actually done to reduce its own footprint?
406 solar panels power our Radford, VA manufacturing facility, covering more than 70 percent of everything our plant and offices run on. We recycle all waste foam from production, use Sustainable Forestry Certified materials, and retrofit our own offices with SIPs, cutting our office energy use by 60%.
ACME Panel is Proudly Green
We started our company to help reduce carbon emissions in a practical and substantive way.
At ACME, our first major investment were the 300 Solar Panels on the roof of our factory to produce green energy to power our manufacturing. From the beginning and now more than ever, we remain committed to our original purpose and to producing the finest, greenest panels using sustainable practices.
We are a family owned company with a mission to build a sustainable future by reducing our carbon footprint and by helping our customers reduce theirs.
