In the realm of building science and energy efficiency, understanding and calculating heat loss is a fundamental skill. Whether you’re an aspiring HVAC technician, an architect focused on sustainable design, or a homeowner looking to optimize your energy consumption, a solid grasp of thermal performance is invaluable. I recently completed the Udemy course “Calcul de la déperdition thermique d’un local” (Calculating Heat Loss in a Room), and I’m excited to share my thoughts.
This course provides a comprehensive guide to the principles and methods behind calculating heat loss in a building space. It meticulously breaks down the process, starting with the absolute basics of heat, temperature, and thermal transfer. The instructor clearly explains why calculating these losses is crucial, highlighting the significant energy and economic implications. The initial modules lay a strong theoretical foundation, covering conduction, convection, and radiation, and introducing key concepts like thermal resistance (R-value) and thermal transmittance (U-value).
What I particularly appreciated was the practical, step-by-step approach to calculation. Module 3 dives deep into the formula Φ = U × S × ΔT, applying it to various opaque and glazed surfaces like walls, roofs, windows, and doors. The inclusion of tables with common material values makes the calculations much more accessible. Module 4 addresses heat loss due to air renewal and infiltration, a critical aspect often overlooked in basic analyses.
The course shines in its practical application. Module 5 features a detailed case study where a hypothetical room is analyzed, with heat loss calculated for each component and a global balance presented. This section even touches upon the indicative sizing of a heating system, bridging the gap between theoretical calculation and real-world application.
Furthermore, the course doesn’t stop at just identifying problems; it offers solutions. Module 6 explores technical strategies for reducing heat loss, such as improving insulation, using high-performance glazing, and implementing double-flow ventilation systems (VMC double flux). It also introduces the concept of energy gains and briefly touches upon thermal simulation software.
The final module provides valuable reinforcement through exercises and a mini-project, allowing learners to apply their newly acquired knowledge. A QCM (multiple-choice quiz) helps validate understanding.
Overall, “Calcul de la déperdition thermique d’un local” is an excellent resource for anyone needing to understand building heat loss. It balances theory with practice effectively, making a complex topic digestible and actionable. The instructor’s clear explanations and structured approach make it suitable for both beginners and those looking to solidify their knowledge.
I highly recommend this course to students in building sciences, energy auditors, HVAC professionals, and even informed DIY enthusiasts who want to improve their home’s thermal performance.
