Shield a corridor light fixture to a dark-sky-compliant full-cutoff design, fixture 2, Holland Avenue / US Highway 90 corridor, downtown Alpine, TX 79830 (public right of way)

A ground-accessible outdoor light fixture along this downtown Alpine corridor throws unshielded glare upward and outward, wasting electricity and washing out the Trans-Pecos night sky that the region's dark-sky tourism and McDonald Observatory research depend on. Standard: ASHRAE Level 1 energy audit plus Living Building Challenge Energy petal screening, applied here against Alpine's high-desert cooling and heating load and its dark-sky night-lighting footprint. Proof: before/after photos (day and night) + fixture spec sheet + power-off confirm + GPS Method (ASHRAE Level 1 energy audit plus Living Building Challenge Energy petal screening, applied here against Alpine's high-desert cooling and heating load and its dark-sky night-lighting footprint.): 1. 1. Confirm the fixture with city staff: ground-accessible, building- or park-pole mounted only, never an overhead utility-owned cobra-head streetlight, and photograph the bare, unshielded fixture before starting. 2. 2. Power off the fixture at its switch or breaker before touching any wiring or lamp. 3. 3. Install a full-cutoff, dark-sky-compliant shield or fixture housing so light points down and not outward or upward, working from a properly rated ladder with a spotter. 4. 4. Restore power and photograph the shielded fixture lit at night alongside the daytime after photo, confirming no upward glare. Done when: before/after photos (day and night) + fixture spec sheet + power-off confirm + GPS

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.

Proof

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.
