Formula Used in “Passive House Savings Calculator”
The Passive House Savings Calculator provides a powerful framework for understanding potential energy savings associated with implementing passive house principles. The core formula used in this calculator can be represented as:
Savings = (E_{Current} – E_{Passive}) times Cost_{Energy} times 12
Where:
- E_{Current} = Energy consumption of the current home (in kWh/year)
- E_{Passive} = Estimated energy consumption of the passive house (in kWh/year)
- Cost_{Energy} = Cost of energy per kWh (in $/kWh)
Step-by-Step Breakdown of the Formula
To accurately calculate your potential savings when transitioning to a Passive House, follow these steps:
- Determine Energy Consumption: Measure your current home’s energy use (E_{Current}) in kilowatt hours (kWh) over a year.
- Estimate Passive Energy Needs: Calculate or project the energy consumption for a Passive House (E_{Passive}), typically lower due to energy-efficient features.
- Find the Cost of Energy: Check your utility bill to find out how much you pay per kilowatt hour (Cost_{Energy}).
- Plug Values into Formula: Substitute the values into the formula to calculate your yearly savings.
Example Calculation
Let’s dive into an example to visualize how to implement the Passive House Savings Calculator with real-world figures:
| Input Variable | Value |
|---|---|
| E_{Current} (Energy consumption of current home) | 12,000 kWh/year |
| E_{Passive} (Estimated energy consumption of Passive House) | 3,500 kWh/year |
| Cost_{Energy} (Cost of energy) | $0.15/kWh |
Now, we will substitute these values into the formula:
Savings = (12,000 – 3,500) times 0.15 times 12
Calculating it step by step:
- 12,000 – 3,500 = 8,500 kWh/year
- 8,500 kWh/year × $0.15/kWh = $1,275/year
- $1,275/year × 12 = $15,300 over 12 years
Total Potential Savings: You would save $15,300 over 12 years by switching to a Passive House, according to our example calculation.
