Key takeaways
- An investment-grade resort project must set standards across four dimensions at the same time: finance, operations, Thai law and ESG.
- It is important to distinguish clearly which standards are legally mandatory, which come from contracts or lenders, and which are strategic options.
- The 12th edition of USALI takes effect on 1 January 2026, and the compliance costs in this article are budget examples only.
This article uses a hypothetical sample project, a 5-star resort on the Andaman coast comprising a hotel, a restaurant collection, wellness & spa and branded residences, to explain the standards framework. The standards are divided into Must Have, Should Have and Nice to Have, from pre-opening through to stabilised operations.
1. Why international standards matter
A good location and attractive design are not enough. What separates an investment-grade project from an ordinary one is a system of standards embedded in day-to-day operations. Banks and institutional investors treat alignment as part of their assessment: for example, they expect USALI-based financial reporting for benchmarking, and they expect ESG data when sustainable finance is used.
2. Hotel standards
2.1 Accounting and reporting
USALI classifies revenue and costs by department and separates undistributed expenses from departmental profit. The current edition is the 12th Revised Edition, published by HFTP and effective from 1 January 2026. Thai legal entities must prepare financial statements under Thai financial reporting standards, and projects with an HMA must consider TFRS 15 and TFRS 16 based on the facts of the contract.
2.2 USALI KPIs
| KPI | Formula | 5-star luxury benchmark (approximate) |
|---|---|---|
| ADR | Room Revenue ÷ Rooms Sold | THB 12,000–25,000 |
| Occupancy | Rooms Sold ÷ Rooms Available | 65–80% |
| RevPAR | ADR × Occupancy | THB 8,000–18,000 |
| TRevPAR | Total Revenue ÷ Rooms Available | THB 12,000–25,000 |
| GOPPAR | GOP ÷ Rooms Available | THB 6,000–12,000 |
| Cost Per Occupied Room | Variable Cost ÷ Rooms Sold | THB 800–1,500 |
| GOP Margin | GOP ÷ Total Revenue | 45–55% |
| EBITDA Margin | EBITDA ÷ Revenue | 35–45% |
| Labour Cost | Total Labour ÷ Revenue | 25–32% |
| F&B Cost | (Food + Bev Cost) ÷ F&B Revenue | 28–32% |
| Energy Intensity | kWh per Occupied Room | 50–80 kWh |
These ranges are a starting framework, not statistics. Check them against actual market data for the relevant period.
2.3 Quality and ratings
Forbes Travel Guide assesses several hundred points from before arrival to departure. AAA Diamond focuses on physical facilities and service. LQA uses mystery shoppers, and the Michelin Guide has extended its hotel rankings through the Michelin Key since 2024.
2.4 Operations and safety
| Standard | Scope | Level |
|---|---|---|
| HACCP | Food Safety | Practical Must Have |
| ISO 22000 | Food Safety Management | Should Have |
| ISO 9001 | Quality Management | Should Have |
| ISO 14001 | Environmental Management | Must Have when specified in EIA conditions or contracts |
| ISO 45001 | Occupational Health & Safety | Should Have |
| ISO 41001 | Facility Management | Nice to Have |
| ISO 50001 | Energy Management | Should Have |
2.5 Sustainability
Consider certification in at least two areas to support green financing, for example LEED for the building and EarthCheck for operations. Supplementary standards include Green Key, Travelife and Green Globe.
2.6 Brand Standards
| Brand tier (example) | Room size (sq m) | Staff-to-Room | F&B Outlets |
|---|---|---|---|
| Ultra-Luxury Resort | 60–100+ | 2.5–3.5 : 1 | 4–6 |
| Luxury International | 50–85 | 2.0–3.0 : 1 | 3–5 |
| Luxury Villa Resort | 70–100 | 2.0–2.5 : 1 | 3–4 |
| Luxury Collection | 45–65 | 1.8–2.5 : 1 | 3–4 |
Use this as a preliminary design framework. Actual values must be taken from the brand standards documents of the chosen brand.
3. Restaurant standards
3.1 Accounting and KPIs
USAR (Uniform System of Accounts for Restaurants) is applied at outlet-level P&L, which is then consolidated into F&B in USALI.
| KPI | Formula | Fine dining (approximate) |
|---|---|---|
| Food Cost | Food Cost ÷ Food Revenue | 28–35% |
| Beverage Cost | Bev Cost ÷ Bev Revenue | 18–25% |
| Total COGS | (Food + Bev) ÷ Total Revenue | 30–35% |
| Labour Cost | Total Labour ÷ Revenue | 28–35% |
| Prime Cost | (COGS + Labour) ÷ Revenue | Below 60–65% |
| Rent / Occupancy | Rent ÷ Revenue | 6–10% |
| EBITDA Margin | EBITDA ÷ Revenue | 15–20% |
| Average Check | Revenue ÷ Covers | THB 2,500–8,000 |
| Table Turnover | Covers ÷ Seats per Day | 1.5–2.5x |
| RevPASH | Revenue per Available Seat Hour | Depends on the restaurant concept |
Prime cost is a key indicator. Above 65%, a restaurant will struggle to be sustainably profitable. The sample project sets a ceiling of 62%.
3.2 Quality and ratings
The Michelin Guide is divided into 1–3 Stars, Bib Gourmand and Selected, while World's 50 Best and Asia's 50 Best are based on voting. The Michelin Green Star recognises sustainability. For food safety, use HACCP, GHP and GMP as appropriate, and consider Halal where the target customers require it.
3.3 Restaurant types
| Type | Avg check (THB) | Food Cost | Service Style |
|---|---|---|---|
| 3-Star Michelin | 8,000–15,000 | 35–40% | Tasting menu, sommelier |
| 2-Star Michelin | 5,000–10,000 | 32–38% | Plated, expert pairing |
| 1-Star Michelin | 3,000–7,000 | 30–35% | Refined casual |
| Hotel Fine Dining | 2,500–6,000 | 30–35% | All-day dining |
| Casual / Bistro | 800–2,500 | 28–32% | À la carte |
| Bar / Lounge | 1,500–3,500 | 22–28% | Cocktails, small plates |
4. Wellness and spa standards
4.1 Industry bodies
The Global Wellness Institute produces research and the Wellness Economy framework, and ISPA publishes an annual benchmark. For therapists, CIDESCO and CIBTAC can be used as reference criteria.
4.2 ISPA KPIs
| KPI | Formula | Luxury spa (approximate) |
|---|---|---|
| Treatment Room Utilization | Hours Used ÷ Hours Available | 50–70% |
| Avg Revenue per Treatment | Revenue ÷ Treatments | THB 4,000–8,000 |
| Average Treatment Length | Total Hours ÷ Treatments | 60–90 minutes |
| Therapist Productivity | Treatments per Therapist Day | 4–6 |
| Capture Rate | Hotel Guests Using Spa | 15–25% |
| Retail-to-Treatment | Retail ÷ Treatment Sales | 8–15% |
| Repeat Client | Returning Customers | 30–40% |
| Service Cost | Direct Costs ÷ Revenue | 22–28% |
| Labour Cost | Therapist + Support ÷ Revenue | 35–45% |
| EBITDA Margin | EBITDA ÷ Revenue | 25–40% |
4.3 Medical Wellness
Services involving medical treatment or procedures may fall within the definition of a medical facility under the Medical Facilities Act and require a licence from the Department of Health Service Support. Check the scope with a legal adviser. JCI is the international standard for medical facilities, and laboratories may consider CAP.
4.4 Wellness Economy
The GWI framework covers categories such as Personal Care & Beauty, Healthy Eating, Physical Activity, Wellness Tourism, Public Health & Prevention, Traditional & Complementary, Mental Wellness and Workplace Wellness. The share of each category changes with the reporting year, so refer to the latest report when using figures.
5. Cross-industry standards
5.1 Service quality
SERVQUAL, NPS, CSAT, proactive review monitoring and quarterly mystery shoppers
5.2 ESG
| Standard | Scope |
|---|---|
| GRI Standards | Sustainability Reporting |
| SASB Standards | Investor-grade ESG Disclosure |
| TCFD / IFRS S2 | The TCFD's Climate-related Financial Disclosures have been handed over for monitoring to IFRS S2. |
| UN SDGs | The 17-goal framework |
| HCMI | Hotel Carbon Measurement |
| Carbon Neutral Certification | Net-Zero Pathway |
| B Corp | Social & Environmental Impact |
5.3 Safety
Reference frameworks may include OSHA, NFPA, WHO Guidelines, ASME and crowd safety standards for large events. Thai building and safety laws, however, take precedence.
5.4 Personal data
The PDPA has been fully in force since 1 June 2022. GDPR applies where customers in the European Union are within scope. PCI DSS applies when accepting cards, and ISO 27001 is the information security management standard.
6. Thailand-specific standards
| Standard | Issuer/regulator | Scope |
|---|---|---|
| Department of Tourism accommodation standards | Department of Tourism | A quality certification, separate from the hotel business licence |
| SHA | Tourism and public health authorities | A COVID-era scheme; check its current status before referring to it |
| Green Hotel | Department of Environmental Quality Promotion | Hotel sustainability |
| Thai Spa Standard | Department of Health Service Support | Wellness businesses under the relevant laws |
| Halal Hotel / Restaurant | The relevant halal certification body | Selected outlets |
| MICE Standards | TCEB | Event & Conference |
| Medical Facilities Act | Department of Health Service Support | Services that qualify as medical facilities |
7. Financial and valuation standards
7.1 Valuation
The DCF and cap rate approaches commonly used in the industry, the RICS Red Book for valuation, and market data from STR/CoStar are frameworks worth knowing.
7.2 Banking and project finance
Loan documents may refer to LMA or APLMA terms, and covenants are subject to negotiation. Example conditions for a luxury hospitality project might be a minimum DSCR of 1.30x, LLCR of 1.40x and PLCR of 1.60x, but the actual thresholds depend on the bank and the project's risks.

11. Conclusion
Raising a project to investment-grade level requires integrating four dimensions: finance based on USALI, TFRS and loan documentation; operations based on brand, food safety and spa benchmarks; Thai law; and ESG. There should be a responsible owner who reports to top management, and an annual compliance dashboard to track the status of each standard systematically.
