1. What is Part G Water Efficiency?

Part G Water Efficiency refers to the calculation of total water consumption per person per day, which includes fixture consumption plus an additional fixed amount. This calculation helps in assessing and improving water efficiency in buildings.

2. How Does the Calculator Work?

The calculator uses the Part G Water Efficiency equation:

Where:

• \( fixture\_consumption \) — Water consumption by fixtures (l/person/day)
• \( 5 \) — Additional fixed water consumption (l/person/day)

Explanation: The equation calculates the total water efficiency by summing up the fixture consumption and adding a fixed value of 5 l/person/day.

3. Importance of Water Efficiency Calculation

Details: Calculating water efficiency is crucial for sustainable building design, reducing water waste, and complying with regulatory standards for water consumption.

4. Using the Calculator

Tips: Enter the fixture consumption in l/person/day. The value must be valid (greater than 0).

5. Frequently Asked Questions (FAQ)

Q1: What is included in fixture consumption?
A: Fixture consumption includes water used by toilets, faucets, showers, and other water-consuming fixtures in the building.

Q2: Why is there an additional 5 l/person/day?
A: The additional 5 l/person/day accounts for miscellaneous water uses that are not covered by standard fixtures, such as cleaning and maintenance.

Q3: What are typical values for fixture consumption?
A: Typical values vary based on fixture efficiency, but modern efficient fixtures often consume between 20-50 l/person/day.

Q4: How can I reduce total water consumption?
A: Installing water-efficient fixtures, fixing leaks, and promoting water-saving behaviors can significantly reduce total water consumption.

Q5: Is this calculation applicable to all building types?
A: While the principle is universal, specific regulations and standards may vary by region and building type. Always check local codes.
