Energy Conservation and Energy Efficiency: Reducing Dependence on Imports
- Energy conservation and energy efficiency are two key strategies that help countries reduce their dependence on imported energy resources.
- Energy conservation focuses on behavioral changes that reduce energy use, while energy efficiency involves technological advancements that improve energy use without compromising functionality.
Both strategies contribute to energy security, cost savings, and reduced environmental impact
Passive House Design (Energy-Efficient Buildings)
Definition
Passive house concept
The Passive House (Passivhaus) concept is an architectural approach that significantly reduces energy consumption for heating and cooling by maximizing natural insulation, ventilation, and solar gain.
Buildings designed using this standard can cut heating and cooling energy use by up to 90% compared to conventional buildings.
Key Features:
- Superinsulation: Thick walls and high-performance windows minimize heat loss.
- Airtight Construction: Prevents energy loss through leaks and drafts.
- Heat Recovery Ventilation (HRV): Ensures fresh air while recovering heat from outgoing air.
- Solar Orientation: Maximizes sunlight exposure in colder climates and minimizes overheating in warm climates.
Effectiveness:
- Reduces heating/cooling demand: Houses require minimal external heating or air conditioning, leading to lower energy imports for gas or electricity.
