AEI / Affiliated Engineers, Inc. presents the Purdue University Center for High Performance Design at the Ray W. Herrick Labs, a 68,000 square foot research building focused on systems and environments that improve building performance. Laboratories and research areas include:
• The Perception-Based Engineering Laboratory enables cross-disciplinary research that measures human behavior against an array of stimuli such as lighting, acoustic environment, air quality, temperature, humidity, airflow, and vibration.
• The Electro-Mechanical Vibrations Area allows for both large-scale testing (e.g., aerospace components) and fine-scale testing (e.g., microprocessor scale) with exceptional isolation of vibration and sound.
• Geoexchange research includes ground/earth analysis and simulation.
• Thermal sciences research includes the development of new HVAC technologies, including the use of psychrometric chambers, indoor air quality chambers, wind tunnels, solar thermal arrays, benchtop experiments, and simulated environmental testing.
• The unique Living Laboratory office wing serves as both working office space and as a test site for building systems and concepts.
• The Powertrain/Engine Test Cell Wing is dedicated to testing alternative fuels and emissions to advance engine fuel economy, horsepower, and torque.

2. Learning Objectives
Understand error margins in Energy Modeling and
CFDs (Computational Fluid Dynamics)—and how they
relate to both sustainable design and lab safety.
Understand Data Acquisition System Architectures—
and the importance of ‘right tool for the job’
options/choices to be made early in a project.
Understand the keys to measurement, metering and
baseline when predicting building systems
performance.

6. An in situ HVAC research factory.
Thermal Systems Laboratory
• Raw idea
• Bench top
• Still very much “what if” stage
Psychrometric Chambers Laboratory
• Commercially viable
• Test in 7,000 ft3 chambers
• Precision energy balance is end goal
Living Laboratories
• Four 20-person office suites
• Highly reconfigurable
• Dedicated empirical baseline
• Quantifiable-primarily;
qualitative-secondarily

12. Living Laboratories
Concept:
Four open-plan, occupied, side-by-
side office spaces with reconfigurable
envelope, lighting, and HVAC/comfort
delivery systems and controls. The
facilities allow independent monitoring
and environmental control with
occupant-environment interaction.
Features:
• Two baseline labs. Two experimental
labs: hydronic and air.
• Highly reconfigurable, modular construction
• Rigorously instrumented
• Dedicated baseline (aka “placebo” spaces)
• Ease of device and instrumentation accessibility and changeover.
Modular, flexible and reconfigurable – comparison and evaluation of
design and control options

28. Air Quality Via Empirical Measurement
Air Quality Chamber
Particle Image Velocimetry Measurement
In PIV measurement, the air is seeded with tracer particles for flow
visualization. The particles are sufficiently small to be assumed to completely
follow the flow dynamics.
29. Air Quality Via Empirical Measurement
Current Subject Environment Examples
Infectious disease air side transmission:
e.g., Ebola, Measles
Clean Rooms: Biological,
Semi-Conductor, Nanofabrication
Aerospace: Thermal comfort, humidification,
cabin pressurization, air filtration
31. “Research in Herrick’s new facilities will
attack some of the most daunting and
complex problems confronting the world,
such as rising energy consumption and
environmental pollution, climate change,
public health, comfort and security, and
issues associated with an aging
population.“
