Apply a reflective lime-wash cool-roof coat to an invited single-story home in Vasna

Vasna's densely packed single-story homes trap heat under dark, uncoated roofs during Ahmedabad's extreme summer heat waves, part of what the city's Heat Action Plan was built to address. A reflective lime-wash coat, applied from a safe standing position, cools the room below. Standard: Ahmedabad Municipal Corporation Heat Action Plan (South Asia's first, since 2013) cool-roof guidance + SDG 11 / SDG 13. Proof: Photo of fully coated, dry reflective roof Method (Ahmedabad Municipal Corporation Heat Action Plan (South Asia's first, since 2013) cool-roof guidance + SDG 11 / SDG 13.): 1. Confirm the household invitation and access the flat roof by interior stairs only. 2. Sweep the roof clear of debris and wash the surface, letting it dry fully. 3. Mix the reflective lime-wash coating per instructions. 4. Apply an even coat with a roller from a standing position only, then a second coat once dry. 5. Photograph the finished white roof with GPS and date as proof. Done when: Photo of fully coated, dry reflective roof

$200 proposed

This packet is not funded yet, so this figure is a proposed price and not money waiting in escrow. If a buyer funds it, approved proof settles that price onchain. If nobody funds it, approved proof earns provable credit toward the work instead of cash. You see which before you claim, never after.

This is exactly what gets it approved. Nothing settles without it.

How this work is done

A documented method, so this packet comes out the same whoever does it. Typically 60–120 minutes. Method of record: ASHRAE Level 1 energy audit

Bring

• tablet/clipboard
• tape measure
• light meter (lighting scope)
• clamp thermometer (refrigeration scope)
• 12-month utility bills
• camera
• ladder + spotter (high fixtures)

Steps

1. 1. Confirm the address; arrange a staff escort for mechanical/back-of-house.
2. 2. Photograph HVAC, lighting, envelope, and any in-scope systems.
3. 3. Inventory systems: HVAC type + age; lighting fixture count/type/wattage; refrigeration units; envelope condition.
4. 4. Summarize 12 months of utility use (kWh / therms) from the bills.
5. 5. Take the in-scope measurements (light levels, unit temperatures, seal condition).
6. 6. Rank no-cost/low-cost measures, then capital measures, with rough savings logic.
7. 7. Enter inventory, measurements, utility summary, photos, and the ranked measure list; sign.

If it does not match the plan

• Knob-and-tube, ungrounded or overheated wiring, scorched outlets, or a hot electrical panel -> STOP: do not operate the circuit; route to a licensed electrician and restrict use (NEC / fire hazard).
• Gas odor, or a combustion appliance with absent/blocked venting (backdrafting / CO risk) -> STOP: evacuate, ventilate, call the gas utility. The agent escalates, never relights or adjusts gas.
• Any live-electrical/gas hazard -> document, do not touch, flag for a licensed pro.
• Refrigeration unit out of food-safe range -> flag as both energy and food-safety risk.
• Suspected asbestos/lead in materials -> flag and stop.

What counts as done

• System inventory complete for the in-scope equipment
• 12-month utility use summary recorded
• In-scope measurements recorded with units
• Ranked no-cost/low-cost + capital measure list produced

Proof is measured against these, not judged by taste.
