that are built for energy efficiency, professional builders must prepare to discuss this topic with their clients and to provide options for a build that promotes energy efficiency and minimal environmental impact.
The ENERGY STAR certification program is one green building certification homeowners may be familiar with. Let's take a look at the basics of the ENERGY STAR rating system and learn how you can use products from LP Structural Solutions to contribute to ENERGY STAR certifications.
Implemented by the United States Environmental Protection Agency (EPA), the ENERGY STAR program focuses on helping businesses and individuals make more energy-efficient choices, which can help them save money and contribute to a healthier environment.
The program began in 1992 with the goal of reducing greenhouse gas emissions. It expanded in 1995 to include more products, and by 1996 the EPA had connected with the United States Department of Energy to establish additional categories. Today, the ENERGY STAR label is on everything from lighting and home electronics to building materials, and it has contributed to massive energy savings over many years (24 $ billion in 2012 alone).
"The overall movement in energy efficiency is to reduce the energy consumption per home," Neil Freidberg, LP Building Science Manager sums up. "While individually it may not be a lot, whole communities designed to this standard have a large impact on the grid."
For buildings, eligibility for ENERGY STAR certification depends on a score of 75 or higher on the EPA's 1-100 scale. This indicates that the structure in question performs more efficiently than 75 % of similar buildings across the nation. The score is based on measured use of energy in the building and can be calculated via the ENERGY STAR Portfolio Manager tool. Certification is checked for compliance yearly, so structures must maintain their scores to continue achieving certification.
The ENERGY STAR rating system doesn’t just provide a label—it creates tangible impacts on the environment. For example, an office building with an ENERGY STAR certification uses 35 % less energy, generates 35 % fewer greenhouse gas emissions, and may even cost less to operate. When builders focus on structures that also achieve ENERGY STAR certification, they can bring similar savings and reductions to their clients in homes all across the country.
When talking with your clients about ENERGY STAR criteria and product selection, being able to communicate the specific benefits of the program is helpful. Here are a few to highlight:
"A benefit that is difficult to put a price tag on is comfort," Freidberg adds. "Because of all the potential items that an ENERGY STAR home can have, the occupants could see a physical effect where they are comfortable in their home more often."
"Codes have started to include an energy path so that builders can choose how they want to make the homes they build more efficient," Freidberg says. "They can choose materials, equipment and techniques to achieve a specific level of efficiency."
When it comes to LP Structural Solutions, LP® TechShield® Radiant Barrier and LP NovaCore™ Thermal Insulated Sheathing both aid in the evaluation of a building to be certified as ENERGY STAR.
LP TechShield sheathing, for example, can help reduce ambient temperature in an attic. "This helps the code-mandated minimum attic insulation to be more effective," Freidberg explains. "LP TechShield sheathing can reduce the attic temperature by up to 30 degrees Fahrenheit. Without LP TechShield sheathing, there can be an increase in the amount of energy required to cool the ceiling surface. This increases the size and amount of cooling required to make your home comfortable, causing more energy consumption, larger HVAC units and potentially a less comfortable experience for homeowners."
LP NovaCore sheathing can contribute to more efficient wall insulation because it provides continuous insulation, according to Freidberg. “These are things that ENERGY STAR looks for when analyzing products and home performance,” he says.
"There are several national programs builders can reach out to," suggests Freidberg. "They can also reach out to home rating companies and ask them for a consultation to look at all the options available based on their climate zones."

New to the LP® Structural Solutions portfolio, LP® NovaCore® Thermal Insulated Sheathing is a dual-layered wall panel design to protect structures against heat loss and gain. It combines resilient OSB sheathing with XPS foam to provide continuous insulation without the long-term R-value deterioration associated with other foam insulation products.Continue Reading
With an abundance of inspiration at their disposal, clients may have design goals that exceed their budget. We talked to building professional Kyle Stumpenhorst to get his tips for helping clients achieve their goals without breaking the bank.
With today's hot housing market the last thing you want to do is stop, backtrack, and address a customer callback. In any economy, callbacks in construction cost money and time-time you may not have. Some builders are dramatically reducing customer callbacks by choosing building products that promote greater performance.
In recent years, the construction industry has seen an upward trend when it comes to spending on new construction with forecasts of 2,5 trillion U.S. dollars in 2025-but the increased numbers don't necessarily point to industry growth. With labor and supply chain shortages continuing to increase, there has been a significant increase in the cost of such goods and services.
