Every audit measures your unit on 9 inputs — facing, Period 9 chart, surrounding sha, road flow, sector qi, building shape, entrance, support behind, and frontage. Each gets an element reading (Fire / Water / Wood / Metal / Earth) and a weight. Together they produce a single locale element profile that gets matched against your trade.
| # | Input | Headline weight | What it captures |
|---|---|---|---|
| 1 | Building facing | ~25% | 24-mountain compass direction the entrance faces |
| 2 | Period 9 flying-star chart | Period overlay (2024–2043) based on facing + build year | |
| 3 | Surrounding sha (杀气) | ~15% | Visible threats: road daggers, knife corners, hospitals, viaducts |
| 4 | Sector qi | ~15% | District element character (Orchard = Fire-Metal, Ubi = Earth, etc.) |
| 5 | Entrance configuration | ~15% | Where qi enters: visibility, threshold, door alignment |
| 6 | Road / virtual water | ~10% | Roads read as Water: flow direction, gradient, intersection proximity |
| 7 | Building shape + material | ~10% | Container effect: glass-tower = Metal, concrete-rectangle = Earth |
| 8 | Support behind (背山) | ~5% | Retention: solid building / hill behind = good; drainage / empty = drain |
| 9 | Frontage / accessibility | ~5% | MRT distance, foot-traffic, line-of-sight from approach |
Weights shift by trade. F&B-cooking-led puts more on facing + Period 9; finance / legal puts more on building shape + sector qi.
Input 3 — Surrounding sha (drag −9). A T-junction road points directly at the unit frontage (路冲, road dagger). Classical severity Tier 4 of 5. The road's Water-element flow drives qi at the entrance rather than letting it accumulate. Remediation: angled door rework, partial visual screening, or a counter-element water feature on the affected side.
Every audit returns a finding like this for each input that moved the score meaningfully — risk side and lever side.
Classical fengshui uses a 24-mountain compass: 8 cardinal directions × 3 sub-divisions each = 24 facings. "Facing" is where the entrance points; "sitting" is the opposite.
Source: satellite + Google Maps. Tier 2 site visit corrects with an on-site compass reading.
Element map: S = Li (Fire), N = Kan (Water), E = Zhen (Wood), W = Dui (Metal), NE = Gen (Earth), SE = Xun (Wood), SW = Kun (Earth), NW = Qian (Metal). 24-mountain subdivisions refine further.
Period 9 (2024–2043) is governed by Li (Fire, South). Every building inherits a Period 9 base chart based on facing + build year (or last major renovation). Annual flying stars cycle on top.
Source: computed deterministically by flying_stars_calculator.py.
Period 9 specifically: south-favored; fire-element trades at peak; water-trades need careful sector placement. See the Period 9 page for full detail.
Sha qi (杀气) = sharp, hostile, draining energy patterns nearby. The audit catalogues:
Each sha has a documented severity scale and remediation options.
Source: intake photos + satellite. Claude vision flags candidates; methodology rules confirm.
Element role: sha contributes drain rather than element — it reduces the effective score for any trade whose element passes through the sha's affected sector.
In classical fengshui, roads are virtual water: they bring qi in and out.
Element role: roads = Water; the flow dynamic adjusts how that Water contributes.
Every SG district has a documented qi profile based on its historical use, current commercial mix, and topography.
| Sector | Element character |
|---|---|
| CBD (Raffles Place, Marina) | Metal |
| Orchard | Fire-Metal hybrid |
| Geylang | Fire (historical) |
| Marina Bay (Sands area) | Water-Metal |
| Tuas / industrial | Metal + Earth |
| Bishan / AMK / Toa Payoh | Earth |
| Tampines / Punggol | Earth (new town) |
| Bukit Timah / Holland | Wood-Earth |
| Ubi / Bedok / Paya Lebar | Earth |
Full sector pages at SG sectors. Per-trade per-sector weights stay proprietary.
The building's own element modifies the unit's effective field. A Wood-trade in a glass tower (Metal building) faces inherent ke-cycle pressure from the container itself.
One of the highest-weight inputs in classical commercial fengshui — qi enters here.
Classical fengshui prizes support from behind. In urban SG:
Support adjusts retention rather than adding element.
The intentional overlap between fengshui and commercial real-estate analysis. The methodology treats these as element-relevant: visibility = Fire, flow = Water, accessibility = Metal.
You submit address + photos + a short intake form. The audit derives all 9 inputs from that — no on-site visit at Tier 1. The report shows you each input's element reading, its contribution to the score (positive or negative), and the top 3 inputs we'd act on first. You don't need to memorise the framework to read the report; the framework is published so the report's reasoning can be verified.
