R-38 Attic Insulation
Lowers Energy Costs
Used in conjunction with Open-Cell Foam Insulation for optimal effectiveness, traditional R-38 insulation serves as a further barrier to heat transfer.
Open-Cell Foam Insulation
Lowers Energy Costs and Reduces Noise
Spray foam insulation is your home’s first line of defense. Applied as a liquid, Open-Cell Foam expands to form a continuous air barrier, sealing leaks and preventing both active and passive heat transfer. Open-Cell Foam Insulation also offers the added benefits of dampening noise, and improving indoor air quality by reducing infiltration of outdoor allergens.
High-Efficiency Light Bulbs
Increases Lighting Efficiency
Provide approximately 90% more lighting efficiency than incandescent bulbs. High-Efficiency bulbs use less electricity, remain cool, save on replacement costs, and provide more light.
Micro-Seal Caulking
Lowers Energy Costs
Applying caulking where Open-Cell Foam Insulation can’t reach completes the air barrier that helps maximize the effectiveness of the energy efficiency measures incorporated in your home.
HERS Scores
Once construction is complete, each homeowner receives a personalized Home Energy Rating System (HERS) score. This score helps us understand how well your home rates in energy efficiency.
Blower Door Testing
Upon completion of construction, we utilize a third-party provider to perform blower door testing. This diagnostic test involves using a powerful fan in an exterior doorway to measure your home’s airtightness. With this, we’re able to verify building performance by ensuring the home is sealed properly.
Programmable Thermostat
Lowers Energy Costs
A Programmable Thermostat offers more comfort for your dollar by creating a custom schedule that matches your daily routine. The combination of a modern climate control system, smart thermostat, and control from anywhere helps optimize your energy usage.
Energy Star Appliances
Lowers Energy Costs
Modern Energy Star® appliances provide the same service, but use less energy. This saves you money on your energy bill and reduces the amount of greenhouse gases going into the atmosphere. When you shop for appliances, think of two price tags; the first one covers the purchase price and the second one is the cost of operating the appliance during its lifetime. The familiar Energy Guide labels can help you shop for energy-efficient appliances.
