Energy rating:
Benefits of High Energy Efficiency
- Lower Bills: Reduced energy consumption means lower utility bills.
- Increased Comfort: Better temperature regulation and reduced drafts.
- Environmental Impact: Reduced carbon footprint and greenhouse gas emissions.
- Property Value: Energy-efficient buildings typically have higher market values.
- Tax Benefits: Potential access to tax incentives and rebates.
- Future-Proofing: Better prepared for stricter energy regulations.
How the Energy Efficiency Score Is Calculated
The Energy Efficiency Score Tool evaluates your building's energy performance based on several key factors:
| Factor | Description | Impact on Score |
|---|---|---|
| Building Type | Different types of buildings have different baseline energy requirements | Affects the baseline energy consumption calculation |
| Construction Year | Year when the building was constructed or last renovated | Newer buildings typically have better energy performance standards |
| Insulation Level | Quality and thickness of wall, roof, and floor insulation | Better insulation significantly reduces heat loss |
| Window Type | Type and quality of windows installed | Modern windows can reduce heat loss by up to 70% compared to single glazing |
| Heating System | Primary method used to heat the building | More efficient systems improve overall energy performance |
| Renewable Energy | Presence of solar panels, geothermal, or other renewable sources | Reduces dependence on external energy sources and improves score |
Score Interpretation:
- A (91-100): Extremely energy efficient, minimal energy usage
- B (81-90): Very good energy performance
- C (69-80): Good energy performance, meets modern standards
- D (55-68): Average energy performance
- E (39-54): Below average, significant potential for improvement
- F (0-38): Poor energy performance, urgent improvement needed
The calculator uses standard industry metrics and formulas to evaluate energy performance. The recommendations are tailored to your specific situation and focus on the most cost-effective improvements.
