Measurement & Verification
2 referenced standards
ASHRAE
ANSI/ASHRAE Guideline 14 — Measurement of Energy, Demand, and Water Savings
Guideline 14-2014, Table 5-2
Statistical acceptance criteria for energy-savings measurement models.
- Hourly regression: CV(RMSE) ≤ 30% and |NMBE| ≤ 10%
- Monthly (utility-bill) regression: CV(RMSE) ≤ 15% and |NMBE| ≤ 5%
- Annual savings uncertainty must be less than 50% of annual savings at 68% confidence
Efficiency Valuation Organization (EVO)
International Performance Measurement & Verification Protocol
IPMVP Core Concepts — Options A/B/C/D
Framework for measuring and verifying the results of energy-efficiency projects.
- Option B — Retrofit isolation, all parameters (measure all inputs to the affected system)
- Option D — Calibrated simulation (whole-facility or system, calibrated to metered data)
- Savings are valid only when they exceed 2× the standard error of the baseline energy model (68% confidence)
Audit & Maintenance
2 referenced standards
ASHRAE / ACCA
ANSI/ASHRAE/ACCA Standard 180 — Standard Practice for Inspection & Maintenance of Commercial Building HVAC Systems
Standard 180
Minimum HVAC inspection and maintenance tasks and frequencies for commercial buildings.
- Prescribes inspection tasks, frequencies, and documentation for HVAC assets
- Frames operational deviations (locked VFDs, low-ΔT, keycard bypass) as maintenance non-conformances
ASHRAE / ACCA
ANSI/ASHRAE/ACCA Standard 211 — Standard for Commercial Building Energy Audits
Standard 211
Defines the scope and deliverables of commercial building energy audits.
- Level 1 — Walk-through analysis
- Level 2 — Energy survey and analysis
- Level 3 — Detailed survey and analysis (investment-grade audit)
- Somerset Greenways baseline framed as Level 3 investment-grade
Commercial Model
1 referenced standard
BASE · SET Alliance · Clean Cooling Collaborative (fmr K-CEP)
Cooling-as-a-Service Initiative — Basel Agency for Sustainable Energy
CaaS methodology & contract framework
Pay-per-use servitisation model for cooling — provider installs, runs and maintains the equipment; user pays a fixed cost per unit of cooling delivered.
- Tariff basis is ₹ per TR-hour delivered (not equipment purchase)
- Provider pays for electricity — strong incentive to install the most energy-efficient equipment
- Zero-capex for the client; efficiency risk sits with the provider
Development Finance
1 referenced standard
International Finance Corporation · UNEP
IFC — Cooler Finance: Mobilizing Investment for the Developing World's Sustainable Cooling Needs (IFC/UNEP, 2024)
IFC Cooler Finance, 2024
IFC's investment thesis for scaling sustainable cooling in developing markets.
- Blended finance guidance for cooling projects
- Highlights CaaS servitisation as a mobilisation vehicle
ESG & Green Building
3 referenced standards
IFC · GBCI
IFC EDGE — Excellence in Design for Greater Efficiencies
EDGE Certification Standard
Green-building certification for emerging markets.
- EDGE Certified: minimum 20% projected reduction in energy, water, and embodied carbon vs a standard local building
- EDGE Advanced: 40%+ energy savings
- EDGE Zero Carbon: on-site + off-site renewables to net zero
GRESB Foundation
GRESB — Global ESG Benchmark for Real Assets
Real Estate Assessment
Investor-driven ESG benchmark for real-estate and infrastructure portfolios.
- Annual assessment scored against sector peers
- Energy-intensity trajectory and verified savings are direct inputs
Securities and Exchange Board of India (SEBI)

- BRSR Core (assured subset) phasing to all top 1,000 by FY 2026-27
- Requires energy-intensity, GHG, and water disclosures
Carbon Markets
1 referenced standard
Ministry of Power · Bureau of Energy Efficiency (BEE)
India Carbon Credit Trading Scheme
Notified 28-Jun-2023, Energy Conservation (Amendment) Act 2022
India's domestic compliance carbon market. BEE is administrator and issuer of Carbon Credit Certificates (CCCs).
