CES Calculo

Use this skill for a preliminary energy-performance review with CES framing.

Normative framing

• CES (Certificación de Edificio Sustentable) is a voluntary certification system (MINVU/IDIEM); Res. Ex. N° 1.827, 10-12-2025, MINVU approves its Application Manual; Manual CES v1.1 is the current evaluation basis.
• CVS (Certificación de Vivienda Sustentable, MINVU) is the analogous system for housing.
• Thermal/energy baselines: OGUC art. 4.1.10 (in force since 28-11-2025) and Ley 21.305.

Operative steps

1. Check references/normative-registry.yml and references/source-lookup-protocol.md before using thermal or energy sources.
2. Identify the building type and climate/location context.
3. Collect available envelope data if present.
4. Summarize the likely leverage points:
   • envelope
   • shading
   • glazing
   • ventilation
   • systems
5. List what must be verified in a formal energy model or certification workflow.

Output shape

• Executive summary
• Inputs reviewed
• Preliminary CES notes
• Improvement opportunities
• Verification items

Guardrails

• Do not claim an official CES score without the underlying model.
• Distinguish between screening advice and certification evidence.
• If thermal or energy data is missing, recover it from references/source-of-truth/ and identify the source category used.
