A Practical Guide: Testing Normative Prompts to Reduce Guest Energy Use
Translating behavioural insights, like using normative prompts to reduce guest energy use, requires accurate, granular measurement. This practical Nudge & Analyse Pilot guide provides the framework for testing these prompts in your hotel. It starkly contrasts the verifiable results from Augos HVAC Circuit Monitoring (Ideal Method) against the severe limitations of basic main meter data, proving why precision is essential for claiming true ROI.
The Challenge: Proving Behavioral Savings
In our previous article, we explored the effectiveness of normative prompts in influencing guest energy behaviour. However, without accurate measurement, it's impossible to verify if your behavioural intervention actually delivers the claimed savings.
Main meter data is too crude to isolate the effect of a guest-facing nudge from other consumption variables. You need granular, circuit-level monitoring to prove ROI.
The "Nudge & Analyse" Pilot: Step-by-Step
This guide provides the necessary framework—the "Nudge & Analyse" Pilot—for translating psychological insight into a measurable, verifiable operational result.
Step 1: Define Scope & Groups
- Objective: Test if a specific normative prompt reduces air conditioner energy usage
- Location: Select two comparable hotel sections (e.g., Wing A vs. Wing B)
- Groups: Designate one as Control (no change) and the other as Test (receives the prompt)
Step 2: Establish Baseline Measurement (Crucial)
- Duration: Collect data for 2–4 weeks before the pilot starts
- Ideal Method: Utilise Augos to monitor dedicated HVAC circuits for rooms in both groups. Calculate average daily kWh per occupied room night (kWh/ORN) for each
- Basic Method: Record total property daily energy use (demonstrates why granular data is essential)
Step 3: Implement the Nudge
Introduce prompts in the Test Group rooms and run for 4–8 weeks while collecting the same data for both groups.
Step 4: Analyse the Results
The most critical step in the pilot is analysis, which starkly reveals the difference between estimation and verification:
- Ideal Method: Compare the change in average kWh/ORN (Intervention vs. Baseline) specifically between Test and Control groups
- Basic Method: Compare overall trends with rough adjustments for occupancy/temperature (cannot confidently attribute savings)
Why Precise Measurement Makes the Difference
Running this pilot, especially when attempting analysis with only main meter data, demonstrates the necessity of precise measurement. Only granular, sub-meter data can truly verify if your behavioural nudge is delivering the expected savings.
The Augos platform uncovers hidden inefficiencies and patterns your main meter cannot see, allowing for targeted optimisation through features like Smart Triggers that alert you to operational deviations.
Localized E-E-A-T Fact
In South Africa's highly competitive hospitality market, accurate kWh/ORN reporting is becoming a key differentiator in sustainability reporting for international corporate bookings. Utilizing granular, sub-metered data validated by Augos provides an auditable, credible energy performance metric that can be leveraged to secure premium contracts and justify verifiable operational savings, minimizing the financial risk associated with unverifiable main meter data claims.
