公共用房照明改造为LED并计量前后功率（滨海新区文化中心公共广场） / Retrofit the public building's lighting to LED and measure the load before and after (the Binhai Culture Centre public plaza, Tianjin, CN).

滨海新区文化中心公共广场的公共用房仍在使用高功率旧灯具，照度不足而电费偏高，改造前后的差值也从来没有被计量过。 / The public building at the Binhai Culture Centre public plaza still runs high-wattage old fittings that light poorly and cost heavily, and the difference a retrofit makes has never been measured.

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 — recorded, and readable any time at vealth.net/labor/credit/(your wallet). You see which before you claim, never after.

Proof

改造前后灯具清单＋照度实测＋回路功率实测＋年节电估算 / fitting inventory before and after + measured illuminance + measured circuit load + estimated annual saving

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.

Steps

1. 由持证电工在配电箱处将该回路断电并挂牌确认无电。 / A licensed electrician isolates the circuit at the distribution board and confirms it is dead.
2. 记录改造前灯具数量、功率与实测照度。 / Record the existing fitting count, wattage and measured illuminance.
3. 更换为LED灯具，接线由持证电工完成。 / Change the fittings to LED, with the licensed electrician making every connection.
4. 复电后实测照度与回路功率。 / Restore supply and measure illuminance and circuit load.
5. 出具前后功率与照度对比及年节电估算。 / Produce the before and after load and illuminance comparison with the estimated annual saving.

What counts as done

• 改造前灯具数量、功率与照度实测 / Existing fitting count, wattage and measured illuminance
• 持证电工断电确认记录 / Record of the licensed electrician's isolation confirmation
• 改造后照度与回路功率实测 / Measured illuminance and circuit load after the retrofit
• 前后对比与年节电估算 / Before and after comparison with the estimated annual saving

Proof is measured against these, not judged by taste.

The standard this serves

Living Building Challenge, Energy Petal. The Energy Petal is the Living Building Challenge's boldest promise: a building that makes more energy than it uses, proven over a full year of lights, laundry, and cold mornings. Mastery looks like a house so tight and so carefully tuned that its rooftop panels run the meter backward. Every such house began the same humble way, with someone finding the leaks and sealing them. A packet like this one, a few honest hours of sealing and measuring, is the first rung of that ladder. Buildings become net positive one closed gap at a time.
