Solid Green Systems is announcing the launch of their patented technology: a wall and roof system based on a foam insulated panel manufactured from expanded polystyrene (EPS), a byproduct generated in the refining of crude oil. When combined with light-gauge metal framing, the EPS adds rigidity in the exterior walls and roof. The resulting patented system provides superior insulation, vapor barrier and sound barrier while reducing air infiltration to result in unparalleled energy efficiency.

David Carolan, Founder and President of Solid Green Systems believes their building system will help meet the growing demand for green and energy efficient structures “As the alternative building market grows at 30% or greater annually, we have invested in a process that allows us to integrate our panels with other technologies to provide a solid, sustainable and smart building solution while being as cost effective for construction as traditional building systems.”According to Carolan, “The panel system provides a sustainable and competitive building system. Increased demand for energy and alternatives continues to drive the need for design and innovation. The system benefits include:

Expanded polystyrene is an organic material manufactured from crude oil by-products. The manufacturing process consists of the expansion of polystyrene beads in a mould, which contains an expanding agent, pentane. When submitted to water vapour, the beads expand until they completely fill the mould. During the expansion process, the expanding agent dissipates and air is introduced to the cell structure. The final product is a rigid insulation comprised of a closed cell structure consisting of 98% air.

What is EPS used for?

EPS is widely used in packaging applications for the transport of produce, seafood and fragile items. EPS is also becoming a popular material for use in building and construction applications. Examples include geofoam, a light-weight void filler, insulated panel systems, wall cladding systems and concrete slab footing systems known as waffle pods.

What are the benefits of using EPS?

EPS is widely used in many everyday applications where its light weight, strength, durability, thermal insulation and shock absorption characteristics provide superior benefits over other materials. These characteristics, combined with its versatility, performance and cost effectiveness have made EPS a packaging and building material of choice for over 50 years.

“It’s one of the most rewarding experiences of my career,” says David Carolan, Founder and CEO of Solid Green Companies, describing his company’s participation in the rebuilding of several homes after the forest fires that devastated Bastrop, Texas, in September 2011, destroying 67 homes. “I’m happy we could step in and quickly help with the rebuilding process. Thanks to our unique wall and roof system we were able to rebuild several homes is just 60 days.”

American Builders Quarterly reported on this story, sharing details of how such a fast build of quality homes was possible, including the ability to get the wall and roof system ready to install in record time. The system allows builders to construct homes and offices approximately 25 percent faster by reducing the work it takes to prepare walls.

As David explains in the article: “From a builder’s perspective, it’s a lot like getting a truss package. You send us the plans and order the system so it hits the jobsite just after the foundation is complete, then you unbundle it and get to work.”

The article also mentions that the wall and roof system is not just appropriate in natural disaster situations, but also in typical building situations — such as homes for oil company workers in Eagle Ford Formation, Texas. “We were able to build the four multiunit apartment buildings the company needed to house its workers in less than 75 days,” said David. “This helped the company keep their project running, with no down time.”

The tipping point for Net Zero homes and office buildings was 2012. That’s when Professional Builder reported on the fact that “the growing number of production builders focused on bringing net-zero energy homes to the masses.” Net Zero is where all energy consumption in a building is offset by the structure’s energy production system.

The article further states: “Unlike their predecessors in the budding ZEH (zero-energy homes) market, which made a living by designing and building primarily one-off, high-cost zero-energy homes, these builders are keenly focused on offering ZEHs on a production scale, and at price points that are affordable to virtually anyone who walks into their sales centers and models.” This watershed moment in the building industry means that Net Zero energy structures have gone mainstream.

As Net Zero energy buildings grow more popular, many have called for a standard language and certification processes. The Net Zero Energy Building Certification has taken on the task — and it is rigorous indeed, according to an article on

The author wrote that it was time to tackle this task, because “you can make a canvas tent net-zero if you have the money to put enough solar panels on it.”

The article notes the urgency for these definitions: “Net Zero energy is quickly becoming a sought-after goal for many buildings around the globe – each relies on exceptional energy conservation and then on-site renewables to meet all of its heating, cooling, and electricity needs.”

The certification will verify that the building actually operates as claimed, “harnessing energy from the sun, wind, or earth to exceed net annual demand.”

The article includes an overview of The David and Lucile Packard Foundation in Los Altos, California — an attractive and inspiring Net Zero Energy Certified building with impressive energy savings.

This year, the Washington Post reported that a third of all new office spaces built in 2011 were green. This high percentage is being driven by corporate tenants’ demand for sleeker and brighter spaces, as well as their growing concern “over rising energy costs.” As a result, they are “seeking to minimize their environmental footprints (and) are putting green office space high on their wish list.”

What’s more, many markets across the country are taking measures to meet federal incentives, for example, the Energy Independence and Security Act of 2007, included energy efficiency requirements for federal buildings.

Washington D.C. is one of these markets. “Since 2009, almost two-thirds of all office space built here has been either LEED-certified or Energy Star efficient. Demand has been strong during their leasing periods, as green buildings command lower vacancies (20.7 percent vs. 17 percent) than non-green counterparts.”

Speaking directing to the increasing demand for green, the article points out that green buildings that have leased quickly, while “multiple non-green buildings in nearby Capitol Hill that delivered during 2009-2010 are still not yet fully leased.”
