Luxury homes offer the architect, builder and buyer a unique opportunity to create dwellings that are distinctive, comfortable and aesthetically pleasing. Increasingly, sustainable design is becoming more important to luxury home owners. Opulence does not need to be wasteful of natural resources. Even large floor plans can prove to be conservation-minded if the architect, builder and homeowner decide to pursue a “green” route. Designing a luxury home that is environmentally responsible must take into account many aspects of the building process including design, construction practices, air sealing and insulation, and material selection. Windows sit at the crossroads of sustainable material selection and luxury design. The right window can reduce energy use, contribute to green building goals and also provide the touch of quality and beauty a luxury home requires.
