Designing Low-Energy Buildings: Principles of Energy Demand

Every building consumes energy, but how we design and use these spaces determines their ultimate environmental impact. Understanding the drivers of energy demand is the first step toward creating sustainable, low-energy structures. This written course guides you through the foundational principles of building physics, occupancy patterns, and energy-efficient design. You will transition from understanding basic thermodynamic concepts to analyzing how architectural choices and modern technologies can drastically reduce a building's carbon footprint. What you'll learn: - Understand foundational energy concepts, heat transfer mechanisms, and thermal comfort definitions. - Analyze how building orientation, insulation, and glazing impact heating and cooling loads. - Evaluate the role of occupancy behavior and internal heat gains on overall energy demand. - Explore modern passive design strategies and high-efficiency ventilation systems. - Apply basic energy balance equations to estimate a building's thermal performance. - Integrate net-zero carbon concepts and smart energy management principles into building design. The text begins with essential terminology and thermodynamic fundamentals before exploring envelope design, occupancy dynamics, and modern efficiency strategies. Through comprehensive explanations and practical written exercises, you will develop a clear framework for analyzing and reducing building energy use. This course is designed for beginners, aspiring architects, sustainability coordinators, and students looking for a solid introduction to building energy performance, with no prior engineering background required.
