Building Insulation and Energy Efficiency

What is the primary concern of the protected volume in a building?

Cold bridges in insulation can help retain heat within a building.

What is the significance of the U-value in building insulation?

A __________ is essential to prevent heat loss around windows and doors.

Match the following energy efficiency levels with their corresponding ratings:

Which of the following is NOT a preventive measure against condensation?

The S-peil energy efficiency rating has replaced the K-peil rating.

What are cold surfaces often a cause of in a building?

The Flemish government sets a maximum allowable __________ for insulation materials.

What does a lower thermal conductivity (λ) value indicate?

Protected Volume

A protected volume is a space that is not heated, but is next to a heated room
The insulated area must be well isolated from adjoining heated rooms
A cold bridge occurs when a heated room transitions to a non-heated room, potentially leading to heat loss
Example of a cold bridge: a non-heated garage attached to a house

Insulation

Insulation is crucial for maintaining the temperature difference between heated and non-heated sections.
If poorly insulated, cold air will enter the non-heated section, leading to wasted energy and problems in the heated area.

Energy Efficiency

The document details various energy efficiency levels (e.g., K33, K45) for different types of buildings (e.g., low-energy homes, passive homes).
Higher K-values represent better insulation
Example: A passive home has a K-value of 00

U-value

U-values relate to the amount of heat transferred through a material or structure.
Lower U-values are ideal as they indicate less heat transfer.
U-values determine maximum heat transfer rates per unit of area (e.g., 0.24 W/m²K)

Windows and Glazing

Double-glazing in windows is a good practice for low-energy homes as it significantly improves thermal efficiency compared to single-glazing.

This quiz explores key concepts related to building insulation, energy efficiency, and the implications of protected volumes. You'll learn about U-values, K-values, and the importance of proper insulation to maintain energy efficiency in buildings. Test your knowledge on how insulation affects heat transfer and energy conservation.
