This comprehensive presentation is designed for architects, engineers, and building specifiers, providing in-depth insights into the effective specification and use of skylights to enhance energy efficiency, natural lighting, and indoor comfort. The session will cover the fundamental principles of skylight design, focusing on key considerations such as light transmittance, Solar Heat Gain Coefficient (SHGC), and U-Values. Attendees will learn how to balance daylighting with thermal performance, ensuring compliance with Building Codes. Practical examples and case studies will illustrate the benefits of using advanced glazing technologies and proper skylight placement to achieve sustainable and comfortable indoor environments. By the end of this presentation, participants will have a thorough understanding of how to specify skylights that meet energy performance criteria, improve occupant well-being, and contribute to the overall sustainability of residential and commercial buildings.
