When to use this service
Start with the decision that needs to be made. For comparing envelope, glazing and building-services scenarios, define the objective and verification criteria before selecting equipment or materials.
Inputs
Provide geometry, climate, materials and operating assumptions. Missing information is recorded as an open question so assumptions do not silently become design facts.
Scope and deliverables
Deliverables: a calculation model with assumptions and option comparisons. The drawings, calculations and consultations are agreed in the brief. Options are compared using consistent starting assumptions.
Stages
Brief → input review → option analysis → agreement → delivery. Each stage records decisions and questions that affect the next.
Scope boundaries
Surveys, specialist investigations, approvals and independent certification are included only where explicitly agreed. Cost and timing depend on scope and input completeness.
