Maximizing natural light in a sunroom while maintaining energy efficiency is crucial. Our sunrooms use energy-efficient windows with low-emissivity (low-E) glass to reduce heat transfer and enhance insulation. Consider a design with more sunlights, as those increase the energy efficiency of the room. Use light-colored or reflective surfaces for flooring and walls to bounce light around the room. Additionally, avoid heavy window coverings that block light when not needed, and instead, opt for adjustable blinds or shades that allow you to control the amount of sunlight entering the room.
