Understand how cold walls and glazed openings affect indoor comfort in winter, with practical guidance drawn from controlled experiments and real-world scenarios.
This technical note explains how room temperature, wall temperature, glazing type, and window coverings interact to shape thermal comfort near cold walls and near glazing openings.
This edition presents the concept of an air–radiation comfort requirement, defined for a plane surface near a wall and explored through experiments in a three-room test setup. It also examines how to meet this requirement in living rooms with different climatic zones, window sizes, and curtain configurations. The discussion covers how glazing type (single vs. double) and shading influence comfort, and how changing heating and ventilation affects results. The work highlights average conditions and how variations in outside temperature, inside temperature, and shading alter comfort outcomes.
- Clear explanation of the air–radiation comfort concept for cold walls and glazing openings
- Practical guidance on selecting window sizes and glazing types for different climates
- How curtains, heating method, and room layout impact perceived comfort
- Data-driven insight from experimental conditions and calculations
Ideal for engineers, architects, energy researchers, and students seeking a concrete, data‑driven look at winter comfort near cold walls and glazed openings.
