Commercial Building Envelope Thermal Performance Assessment

Act as an experienced commercial architect specializing in high-performance building envelopes and façade coordination.

Conduct a preliminary thermal performance assessment using the information below.

Project location and climate:

Building type, form, and orientation:
{{building_form}}

Envelope assemblies and glazing:
{{envelope_systems}}

Internal loads and operating profile:

Codes, cost, maintenance, and project constraints:

Assessment requirements:

1. Summarize climate drivers affecting the envelope:
   - temperature;
   - humidity;
   - solar exposure;
   - wind;
   - rainfall;
   - diurnal swing;
   - seasonal variation;
   - coastal exposure;
   - freeze-thaw where relevant; and
   - future climate conditions where supplied.
2. Review building form and orientation for:
   - surface-area-to-volume ratio;
   - façade exposure;
   - self-shading;
   - atria;
   - courtyards;
   - roof area;
   - thermal zoning; and
   - solar asymmetry.
3. Review opaque assemblies for:
   - insulation continuity;
   - thermal bridges;
   - air barriers;
   - vapor control;
   - water management;
   - condensation;
   - penetrations;
   - interfaces;
   - durability; and
   - constructability.
4. Review glazing for:
   - window-to-wall ratio;
   - orientation;
   - U-value;
   - solar heat gain;
   - visible transmittance;
   - frame performance;
   - edge-of-glass effects;
   - glare;
   - daylight;
   - operability;
   - spandrels; and
   - maintenance.
5. Review shading by orientation, including overhangs, fins, screens, dynamic systems, vegetation, and internal blinds.
6. Review high-risk interfaces:
   - slab edges;
   - parapets;
   - roofs;
   - podiums;
   - balconies;
   - canopies;
   - curtain-wall anchors;
   - doors;
   - louvers;
   - loading bays;
   - plant rooms;
   - ground contact; and
   - expansion joints.
7. Assess likely implications for:
   - peak heating and cooling;
   - annual energy;
   - comfort;
   - condensation;
   - perimeter zoning;
   - HVAC sizing;
   - resilience;
   - acoustics;
   - daylight;
   - embodied carbon;
   - maintenance; and
   - replacement.
8. Develop at least three envelope improvement packages:
   - low-cost optimization;
   - balanced performance upgrade;
   - high-performance option.
9. Compare packages for performance, cost complexity, maintenance, aesthetics, constructability, and risk.
10. Create a thermal-bridge and interface register.
11. Identify simulation, testing, mockup, and commissioning needs.
12. Do not invent thermal values, simulation results, climate data, costs, condensation outcomes, or code targets.
13. Do not certify energy, hygrothermal, façade, waterproofing, fire, structural, or code compliance.
14. Flag all items requiring façade, energy, mechanical, structural, fire, waterproofing, acoustic, daylight, sustainability, cost, commissioning, and authority review.

Present the result as:
