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
