What do we use IES VE for?

Integrated Environmental Solutions – Virtual Environment (IES-VE)

• Building load calculations

• Annual parametric energy analysis

• LEED energy modeling

• Double wall studies

• Solar shading analysis

• Airflow analysis within and around buildings

• Computational fluid dynamics

Analyzing Double Skin Façade for Different Global Climate Regions

Objective:

Comparison of Double Skin Façade (DSF) with Non-DSF for Chicago, Toronto, Las Vegas, London, Cairo, Abu Dhabi, & Shanghai

Metrics:

•Solar gain

• Sensible load

• Process energy

• Surface temperature

• Annual energy consumption

• Carbon emission

• Comfort Index

Analyzing Double Skin Façade for Different Global Climate Regions

Building description

Floor area:

• DSF model – 11,400 square feet per floor

• Non-DSF model – 11,000 square feet per floor

• Cavity width – 1 feet

• Mechanically ventilated façade system

Fully glazed:

• Exterior skin – Double pane

• Interior skin – Single pane monolithic

Mechanical System: As per ASHRAE 90.1-2007

• Variable air volume with reheat

• Water cooled chiller & natural gas fired hot water boiler

Analyzing Double Skin Façade for Different Global Climate Regions

Modeling process:

• Create 3-Dimensional geometry

• Assign operation schedule, operating set points to spaces

• Assign material properties to envelope

• Assign template mechanical systems or create your own HVAC network

• Run full year simulation

• View multiple simulation outputs with weather variables

• View animations
