Gas Consumption Estimator
Gas Consumption Estimator
Calculate your annual natural gas consumption based on your home and usage habits.
How to Use This Calculator
This calculator allows you to estimate your annual natural gas consumption based on your housing characteristics and usage patterns.
Basic Usage
Follow these simple steps to calculate your gas consumption:
- Select your housing type (house or apartment)
- Enter your home's surface area in m²
- Specify the number of inhabitants
- Choose your insulation quality
- Select your gas usage types and enter the price per m³
Factors Affecting Consumption
Several factors impact your natural gas consumption:
- Housing Type: Houses generally consume more than apartments
- Surface Area: Larger surface areas increase heating consumption
- Insulation Quality: Poor insulation can increase consumption by 30%
- Number of Inhabitants: Affects hot water and cooking consumption
- Usage Types: Heating, hot water, and cooking have different consumption patterns
Calculation Method
The calculation is based on French energy consumption standards:
Formulas used:
- Heating: Surface × 100 kWh/m²/year (house) or 80 kWh/m²/year (apartment)
- Hot water: 1500 kWh/person/year
- Cooking: 300 kWh/person/year
- Conversion: 1 m³ of gas ≈ 10.3 kWh
Calculation Examples
Here are some concrete examples to better understand:
Example: Single-family House
Scenario:
- Surface: 120 m²
- Inhabitants: 4 people
- Insulation: Good
- Usage: Heating + Hot water + Cooking
- Price: €0.08/kWh
Estimated result: ≈ 1,800 m³/year or €1,440/year
Example: Apartment
Scenario:
- Surface: 70 m²
- Inhabitants: 2 people
- Insulation: Good
- Usage: Heating + Hot water
- Price: €0.08/kWh
Estimated result: ≈ 840 m³/year or €672/year

Frequently Asked Questions
How accurate is this gas consumption calculator?
Our calculator provides estimates based on French energy consumption standards and national averages. The accuracy typically ranges from 80-90% for standard homes. However, actual consumption can vary due to personal habits, local climate, equipment efficiency, and building characteristics.
What factors most influence my gas consumption?
The main factors are: 1) Home insulation quality (can impact consumption by 30-50%), 2) Surface area to heat, 3) Housing type (houses vs apartments), 4) Number of inhabitants, 5) Usage types (heating, hot water, cooking), and 6) Local climate conditions.
Why do houses consume more gas than apartments?
Houses typically have more exterior walls exposed to outside temperatures, larger surface areas to heat, and often less efficient heating systems compared to apartments in buildings with shared walls and centralized heating.
How can I reduce my gas consumption?
Key strategies include: improving insulation, setting thermostats to 19°C in living areas and 16°C in bedrooms, regular boiler maintenance, using programmable thermostats, sealing air leaks, and adopting energy-efficient habits like brief daily ventilation.
What's the difference between kWh and m³ for gas?
kWh (kilowatt-hours) measures energy content, while m³ (cubic meters) measures gas volume. The conversion factor is approximately 1 m³ = 10.3 kWh for natural gas, though this can vary slightly based on gas composition and pressure.
How often should I check my gas consumption?
Monitor your consumption monthly to track patterns and identify unusual increases. Annual reviews help you assess the effectiveness of energy-saving measures and plan for seasonal variations in usage.
Does the number of inhabitants significantly affect gas consumption?
Yes, particularly for hot water and cooking. Each additional person typically adds about 1,500 kWh/year for hot water and 300 kWh/year for cooking. However, heating consumption is mainly determined by surface area and insulation quality.
When is the best time to use this calculator?
Use the calculator when moving to a new home, planning energy improvements, comparing gas suppliers, budgeting for annual expenses, or after making home modifications that might affect energy consumption.
