Comprehensive Study Guide: Insulation, Solar Thermal, and Renewable Energy Systems

Flashcards covering essential vocabulary and definitions from the Comprehensive Study Guide on insulation, solar thermal systems, and renewable energy.

Dewpoint

The temperature at which air becomes fully saturated with water vapor, leading to condensation.

Heat Transfer

The movement of heat through conduction, convection, and radiation in buildings.

Conduction

Heat transfer through solid materials, such as walls or floors.

Convection

The transfer of heat through air movement, such as warm air rising to the roof.

Radiation

The transfer of heat through infrared waves, like sunlight warming surfaces.

R-value

A measure of insulation's effectiveness; higher R-values indicate better insulation performance.

Vapor Barrier

A material installed to prevent humidity from reaching cold surfaces, typically made of polyethylene.

Occam’s Razor

A principle suggesting that the simplest solution is often the best; applies to building design.

Single-Point-of-Failure

A design flaw where the failure of a single component causes the entire system to fail.

Thermal Mass

Materials that absorb and store heat, releasing it slowly; beneficial for passive solar homes.

Frost Patterns

Visual indicators on roofs that reveal thermal performance, showing areas of heat loss.

Blower Door Test

A method for measuring air leakage in buildings by depressurizing them.

Smart Vapor Retarders

Advanced vapor barriers that adjust their permeability based on humidity levels during different seasons.

Multi-Pane Windows

Windows designed with multiple layers to enhance insulation and reduce heat loss.

Net Metering

A billing mechanism that credits solar energy system owners for the electricity they add to the grid.

Pumped Storage

A method of storing energy by moving water between reservoirs, used to balance supply and demand.

Low-Emissivity Coatings

Thin films applied to windows that reflect infrared energy while allowing light to pass through.

Ductless Mini-Split Heat Pumps

Heating and cooling systems that do not require ductwork, improving efficiency and reducing energy loss.

Reflective Barriers

Materials, like foil, that reflect radiant heat away from living spaces, improving energy efficiency.
