Example Energy Audit Report: Los Pollos Hermanos - Restaurant

1. Executive Summary

The energy audit for Los Pollos Hermanos reveals efficient electricity usage patterns for a quick-service restaurant. Despite the efficient energy practices, opportunities exist to optimise costs and reduce the energy footprint further, ensuring smooth operations for the "front business."

Key Findings:

• Total Consumption:  During October 2024, Los Pollos Hermanos consumed approximately 320.5 kWh (equivalent to 3,846 kWh annually). This is relatively low compared to typical quick-service restaurants, which average around 14,500 kWh per year.

• Cost Comparison:

  • Under the market average tariff, their monthly energy cost was £110.45.

  • By switching to Tariff Tribe, their cost could be reduced to £86.05, resulting in a potential monthly saving of £24.10.

  • A time-of-Use (TOU) tariff that offers lower rates for weekend usage could reduce costs further to £89.64, aligning with their higher weekend energy usage patterns.

• Usage Patterns:

  • Most energy is consumed during weekdays, reflecting operational activity.

  • Weekend usage, while lower overall, represents a significant proportion of their total consumption, suggesting a potential for cost savings with a TOU tariff.

Opportunities for further savings:

1. Switching to Tariff Tribe: Offers the most immediate savings by lowering their energy rates and standing charges.

2. TOU Tariff: Tariffs with specific off-peak times align well with Los Pollos Hermano's energy usage patterns, particularly for weekend activities.

3. Low standing Charge: Because you have relatively low electricity consumption, it is worthwhile trading off a lower standing charge for slightly higher unit rates.

4. Energy Efficiency Measures: Implementing small changes, such as upgrading to energy-efficient appliances and optimising usage schedules, can further reduce costs and consumption.

2. Current Energy Consumption Analysis

2.1 Total Weekly Energy Consumption

Los Pollos Hermano's weekly energy consumption demonstrates variable weekly energy consumption

Insights:

• Consumption is volatile across the weeks, with significant spikes and troughs.

• Slight variations may correspond to specific activities or events but are minimal overall.

3. Consumption Patterns

3.1 Average Daily Energy Consumption

Los Pollos Hermano's daily energy consumption patterns reflect operational priorities, with higher usage during weekdays and lower activity on weekends.

Insights:

• Weekdays: Energy consumption is higher, aligning with typical organisational activities. This suggests that most of Los Pollos Hermanos’s energy usage supports core operations.

• Weekends: Usage drops significantly, reflecting reduced activity levels. This indicates that weekend consumption is limited to essential or standby operations.

3.2 Half-Hourly Energy Consumption

Graphs:

Energy usage patterns throughout the day provide a granular view of how and when electricity is consumed. A TOU tariff could amplify these savings by taking advantage of lower weekend rates.

Insights:

• Weekdays:

  • Peak consumption occurs between 9 AM & 4 PM, corresponding to core operational hours.

  • Energy use tapers off after 5 PM, reflecting reduced activity outside of business hours.

• Weekends:

  • Energy usage is lower overall but shows a slight increase around midday, possibly due to specific maintenance or limited activities.

  • Minimal energy is used in the evenings, indicating efficient energy management during non-operational hours.
