Green building has moved from a trending industry practice to an industry standard. With the growth in demand for sustainable practices, there are a host of initiatives surrounding green building codes and standards. Keeping track of these standards can be difficult. We've created a resource for building professionals to refer to as you navigate the world of green building.
Generally, green building codes are the standards implemented by a state or organization to ensure environmental practices in the building industry. According to the U.S. Green Building Council, these codes aim to address sustainable tactics such as water, energy and resource conservation. Implementing these standards helps ensure longevity in the building industry and contributes to a cleaner world by reducing toxins and harmful emissions.
The green building code glossary below breaks down the must-know terms for rating systems, initiatives and codes commonly implemented in green building.
LEED, a program started by the USBGC, is the most widely used green building rating system. It operates through a four-level point-based certification that rewards projects for implementing green building strategies:
Certified: 40-49 points
Silver: 50-59 points
Gold: 60-79 points
Platinum: 80+ points
Depending on the attributes of your building, it may be eligible for LEED credits that range in point value and category. For example, a building built to accommodate bikes would get a "Bicycle Facilities" credit, which is one point in the location and transportation category. If that same building used a product like LP FlameBlock panels it could qualify for "Heat Island Reduction," which is two points in the sustainable sites category. These credits add up for placement under one of the four LEED levels.
The HERS index is the industry standard to measure a home's energy efficiency. The lower the HERS score, the more energy-efficient a home operates. LP® TechShield® Radiant Barrier can help builders meet various energy codes, including HERS, by blocking up to 97 % of radiant heat transfer through roof sheathing.
SFI is an independent, nonprofit organization that provides sustainable forestry options and voluntary certification opportunities. There are three standards of certification through SFI, all of which LP is certified to. These standards of Forest Management, Fiber Sourcing and Chain of Custody ensure the responsible forestation of wood building materials.
According to the state of California, buildings that qualify as ZNE produce the same amount of clean renewable energy as they consume each year. As of 2020, the state required that all new residential construction was ZNE with commercial construction to follow by 2030. LP WeatherLogic® Air & Water Barrier helps make this possible by creating a tighter home with the seams taped up, which helps protect the build from the elements by preventing air from leaking in and out.
Understanding green building standards will equip you to meet codes and improve your builds. Visit this page for more information on LP’s commitment to environmental responsibility.
The trend to live near downtown hasn't waned in recent years. However, finding empty lots to construct new houses continues to pose a challenge. Builders are finding solutions within the Horizontal Property Regime (HPR) zoning policy, which allows tall and skinny row homes. However, with as little as six feet between structures the potential for row home fires dramatically increases. Let's take a look at some of the concerns for both builders and homeowners-and how LP® FlameBlock® Fire-Rated Sheathing can help builders meet code.Continue Reading
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.
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.
