Three Prompts to Build a Personal Heatwave Cooling Plan

posted on X

Delhi just hit 44.5°C the hottest April day in recorded history. At 2:37 AM, my friend (a senior product manager in Noida, 3BHK apartment) messaged me: “Bro, I’m done. AC running 24×7. Electricity bill already crossed ₹11,200 this month. We can’t sleep, can’t focus, can’t work.” Then he did something actually smart. Instead of complaining or buying expensive gadgets, he used Claude 4.7 to build a personal Heatwave Survival System in 12 minutes. Result in 7 days: Cooling cost dropped 42% → Saved ₹4,700 without buying anything new. Here are the exact 3 prompts he used (copy-paste ready for any city facing this heat): 1. Heatwave Analyzer “Act as an elite energy optimization expert. Delhi/NCR at 44.5°C heatwave. 3BHK home, two 1.5-ton ACs, electricity rate ₹8/unit. Build the most efficient daily cooling plan that keeps indoor temp under 26°C at minimum cost.” 2. Smart AC Schedule “Create a precise 24-hour AC + fan schedule for this extreme heatwave. Prioritise deep sleep at night and lowest cost during day. Give exact on/off times + expected savings.” 3. Bill Predictor “Calculate exact electricity cost for the above plan vs running AC 24×7. Show daily and weekly savings in rupees with clear comparison.” This heatwave is exposing how expensive “normal life” has become. But the winners aren’t the ones buying bigger ACs. They’re the ones using AI to outsmart the heat. Serious question for verified professionals: Are you using AI to fight this heatwave and cut bills? Reply with your city + one prompt or hack that actually worked. (Example: Gurugram - Smart AC schedule saved me ₹5k)

Use these three Claude prompts to generate a cost-optimized AC schedule and predict electricity bill savings during a heatwave.

Prompt

1. Heatwave Analyzer
"Act as an elite energy optimization expert. Delhi/NCR at 44.5°C heatwave. 3BHK home, two 1.5-ton ACs, electricity rate ₹8/unit. Build the most efficient daily cooling plan that keeps indoor temp under 26°C at minimum cost."

2. Smart AC Schedule
"Create a precise 24-hour AC + fan schedule for this extreme heatwave. Prioritise deep sleep at night and lowest cost during day. Give exact on/off times + expected savings."

3. Bill Predictor
"Calculate exact electricity cost for the above plan vs running AC 24×7. Show daily and weekly savings in rupees with clear comparison."

Why it works

Each prompt is scoped to a single, concrete task — analysis, scheduling, and cost calculation — which prevents the model from producing vague advice and instead forces structured, actionable output. Providing specific parameters (home size, AC tonnage, electricity rate, target temperature) gives the model the variables it needs to do real arithmetic and generate a plan that maps directly to the user's situation. Sequencing the prompts matters: the first establishes the constraints and goal, the second converts that into a time-based schedule, and the third quantifies the financial impact. This chain of reasoning mimics how a consultant would work through the problem, and each step builds on the previous output. The bill predictor prompt in particular works well because it asks for a direct before/after comparison in concrete currency, which makes the recommendation actionable and verifiable — the user can check the model's math against their actual bill.

When to use

•You're running ACs continuously and want to reduce electricity costs without buying new hardware
•You need a room-by-room or time-of-day cooling schedule tailored to your specific home layout and local electricity tariff
•You want to estimate bill savings before committing to a new cooling routine, so you can decide if the trade-offs are worth it
