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

围护部位清单与照片＋漏风点标记记录＋温差实测＋排序改造清单 / envelope element inventory with photos + marked draught paths + measured temperature difference + ranked retrofit list

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. 逐个围护部位记录构造与保温现状。 / Record the construction and current insulation at every envelope element.
2. 用手感与飘带法逐处标记漏风点。 / Mark every draught path by hand feel and a tell-tale ribbon.
3. 记录门窗密封条状况与缺失长度。 / Record the condition of the door and window seals and the missing lengths.
4. 测量并记录代表性房间的室内外温差。 / Measure and record the indoor to outdoor temperature difference in representative rooms.
5. 出具按投入产出排序的改造清单与粗略工程量。 / Produce a retrofit list ranked by payback with rough quantities.

What counts as done

• 逐个围护部位的照片与构造记录 / Photo and construction record for every envelope element
• 漏风点位置标记与照片 / Draught paths located and photographed
• 门窗密封条缺失长度实测 / Measured length of missing door and window seal
• 室内外温差实测与排序改造清单 / Measured temperature difference with the ranked retrofit list

Proof is measured against these, not judged by taste.

The standard this serves

Weatherization Readiness. Weatherization readiness is the survey that turns a cold, expensive-to-heat home into a fundable plan. Following the Department of Energy's program, the surveyor maps where the house leaks air, which attics and walls lack insulation, what fresh-air path must follow the tightening, and which safety checks must clear first. Mastery looks like a walkthrough that ends with a package a weatherization crew can price without a second visit. This packet is one piece of one such survey, done carefully and written down, so a real family's real house gets closer to warm.
