Our LEED Energy Modelling Process
1
3D Building Geometry
AutoCAD polylines converted to DXF and imported to DesignBuilder. Geometry organised by floor and space type.
2
Lighting Load Calculation
LPD computed from the lighting plan or the Dialux report. Proposed and baseline both modelled.
3
HVAC Understanding
Mechanical schedule reviewed end to end. AHU to zone mapping logged. Fresh airflow per person and per area documented to ASHRAE 62.1. Per room airflow recorded.
4
Proposed & Baseline Modelling Setup
Proposed case: Space templates per ASHRAE 90.1, actual lighting wattages, consistent operational hours, detailed HVAC system & fan efficiency.
Baseline case: ASHRAE 90.1 Appendix G & Section G3.1.1, lighting controls per Section 9.4, baseline fan power within allowed limits.
Baseline case: ASHRAE 90.1 Appendix G & Section G3.1.1, lighting controls per Section 9.4, baseline fan power within allowed limits.
5
Simulation Run
Unmet hours rectified. ABUPS reviewed. End use breakdown interrogated where any single end use looks unexpected.
6
LEED Energy Simulation Report
Same template every time. Includes: list of contents, list of figures, list of tables, software validation statement, construction details, internal gains, HVAC network (proposed & baseline), results.
7
MEPC Filed
All required modelling files and documents organised and submitted.
8
USGBC Review Comments Rectified
All review comments addressed.
9
Final Delivery
Model modified, report updated, and response narratives written in the language the reviewer expects.
