Description
David Weeks introduces the Passive House approach as a holistic framework for ultra-low energy building design, integrating insulation, airtightness, and efficient ventilation to achieve comfort, energy savings, and environmental performance.
Key Points:
- The Five Core Passive House Principles: These include high-performance insulation, airtight construction, thermal bridge-free detailing, high-specification windows, and mechanical ventilation with heat recovery (MVHR).
- Energy and Moisture Management: Proper calculation of U-values, control of air leakage, and positioning of vapor control layers are essential for thermal efficiency and moisture protection, with standards like BS 5250 guiding best practices.
- Ventilation and Certification: MVHR systems and heat pumps require precise design, testing, and certification to maintain air quality and operational efficiency, highlighting the importance of installer training and continuous performance monitoring.
Learning Objectives:
- Understand the passive house design framework and how its principles reduce heating demand and improve occupant comfort.
- Identify how insulation, airtightness, and moisture control interact to influence building performance, durability, and health.
- Evaluate the role of certified ventilation and heating systems in delivering sustainable and efficient building operations.
