Energy Efficiency Showdown: New Builds vs. Deep-Energy Retrofits

New construction homes often boast significantly lower utility bills, thanks to modern building codes and advanced materials focused on energy efficiency from the ground up. These homes are designed with airtight envelopes, high-performance insulation, and efficient HVAC systems, leading to substantial savings for homeowners. However, older homes can still achieve comparable energy performance through a comprehensive deep-energy retrofit, transforming them into remarkably efficient living spaces.

Here's why new builds often have the edge and how a retrofit can close the gap:

• Superior Insulation: New homes use advanced insulation techniques and materials, reducing heat loss/gain.
• Airtight Construction: Modern builds prioritize sealing gaps and cracks, minimizing drafts and energy waste.
• High-Performance Windows: Double or triple-paned windows with low-emissivity coatings are standard in new construction.
• Efficient HVAC Systems: Newer heating, ventilation, and air conditioning systems are designed for optimal energy use.
• Renewable Energy Integration: New builds are often prepped for or include solar panels and other renewable energy sources.

A deep-energy retrofit tackles these areas in an existing home, often including upgraded insulation, air sealing, new windows, and efficient mechanical systems, aiming for near net-zero energy consumption.
