Energy-efficient design connects architecture, envelope and services. The brief and agreement define the actual scope, not the service name alone.
When to start
The most options remain open before shape, glazing and service routes are fixed. For an existing design, first establish what can change without disrupting other agreed packages.
Inputs
Provide room requirements, site, orientation, available utilities and budget constraints. Supply verified surveying and ground information or record the need to commission them separately.
Coordinating disciplines
Architecture defines geometry, structure defines load-bearing solutions and services define systems and routes. The energy balance compares options and informs envelope and equipment requirements.
Client deliverables
The Studio page describes a coordinated concept, agreed design packages and details. List drawings, calculations and consultations in the brief with delivery formats and acceptance criteria.
Boundaries and common mistakes
Investigations, specialist inspections, approvals and independent certification are not automatic inclusions. Do not replace missing data with optimistic assumptions or buy systems before loads are coordinated.
| Item | Parameter | Check / result |
|---|---|---|
| Architecture | Geometry and use | Concept |
| Calculations | Comparable inputs | Rationale |
| Documentation | Agreed list | Delivery |
What this means for your project
Start with the decisions and outputs you need. Agree discipline boundaries and responsible specialists before work begins.
