Concept Design LOD 100—Conceptual | Preliminary Design LOD 200—Approximate Geometry | Developed Design LOD 300—Precise Geometry |
Evaluate micro-climate conditions | Study building geometry, spatial configuration, layouts and wall-to-window ratio (WWR) to reduce envelope heat gains and losses | Refine and finalize the detailed architectural design from inside to outside and top to bottom specifying all characteristics of the envelope, openings, constructions types, materials, layers and thermal properties |
Study large scale design alternatives (e.g. building masses and form) | Identify and access the high-performance options based on lifecycle cost (LCC) | Complete advanced analysis of the selected options (architectural and mechanical) |
Investigate building orientation to maximize daylighting | Run the preliminary ES to estimate the heating and cooling loads | Run the final ES to provide a detailed and accurate building energy prediction |
Evaluate the building site and topology | Select the Heating Ventilation Air-Conditioning (HVAC) | Life Cycle Inventory (LCI) data source |
Assess steady-state operational energy calculation | Assess dynamic operational energy calculation | Assess embodied energy calculation |
