Energy Efficiency
The energy efficiency of Structural Insulated Panels (SIPs) is a key factor in long-term cost savings. SIPs have a high R-value, meaning they provide superior insulation compared to traditional building materials. This increased insulation leads to lower energy consumption for heating and cooling, which directly translates to reduced utility bills for homeowners. According to studies from Oak Ridge National Laboratory (ORNL), SIP-built homes can be up to 15 times more airtight than conventional homes, significantly reducing heat loss due to air leakage, which accounts for up to 40% of a typical home's energy loss.
Proposed energy scores for SIP-built homes are projected to be significantly higher than traditional construction, with an estimated reduction of energy usage by up to 40-60%. The predicted monthly electrical costs for these homes could be as low as $50-$75, depending on the climate and household size. Additionally, homes built with SIPs often achieve Home Energy Rating System (HERS) ratings of 50 or lower, which means they are at least 50% more energy efficient than standard new homes.
The U.S. Department of Energy also indicates that SIPs can save up to 50% on energy costs over their lifespan compared to traditional stick-framing. These documented savings highlight the significant cost benefits of using SIPs for affordable housing projects, making them an ideal solution for energy-efficient and sustainable living.
Energy savings are particularly important for low-income households, as they often struggle with high utility costs. By reducing energy consumption, SIP-built homes help families save money on a monthly basis while also contributing to environmental sustainability goals.
Rapid Deployment
The prefabrication of Structural Insulated Panels (SIPs) allows for significantly faster construction times compared to traditional building methods. SIPs are manufactured off-site in a controlled environment, which reduces on-site labor and construction delays caused by weather or other unforeseen factors. This quick turnaround is crucial in regions like Alabama, where the demand for affordable housing is growing faster than traditional construction can meet.
International factories have demonstrated the capability to produce up to 6,000 units per year, highlighting the efficiency of modular construction. However, our approach focuses on using local assembly factories that can produce one unit per day. This localized model helps to reduce transportation costs, create jobs within the community, and ensure that production is responsive to regional housing needs.
The process begins with component suppliers, such as steel manufacturers, SIP panel manufacturers, and windows manufacturers. These components are delivered to a centrally located assembly plant, where the final package is assembled. By partnering with large manufacturers to supply pre-drilled and pre-tapped components, our assembly factories can focus on efficient, low-skill assembly work, similar to the concept of assembling IKEA furniture.
This approach not only minimizes the need for specialized labor but also reduces transportation complexities. Since the assembly plants are located closer to the target markets, transportation costs are lower, and the environmental impact is reduced. Once assembled, the final packages are loaded onto flatbed trucks and transported to the site, ready for installation. The ultimate goal is to produce housing units efficiently while providing good-paying jobs in the community.
Durability of Modular Homes
