Human Thermal Comfort

Our human thermal simulation technology places test dummies in complex environments.Our human thermal simulation technology places test dummies in complex environments.

The virtual human is composed of individual body segments that allow the  user to define individual layers of clothing and highly localized heating and cooling loads. The methods and parameters of the model were developed by our team of thermal simulation researchers, including in-house subject matter experts Dr. Mark Hepokoski and Dr. Allen Curran, who regularly contribute literature to the scientific community. The environmental models support full weather inputs, solar models, transparent glass with greenhouse effects, and all other significant thermal variables. Multiple humans can be placed into realistic systems to capture the net human metabolic load, which can be included as part of the total system energy load when necessary. 

Berkeley Comfort Model

The Berkeley Comfort Model provides localized sensation and comfort results for each body segment computed from temperatures predicted by our Human Thermal Module. The Berkeley Comfort Model was developed at the University of California-Berkeley’s Center for the Built Environment. It is an advanced design tool for assessment of localized thermal comfort designs and functions as a module in our software.

The Berkeley Comfort Model enables an engineer to study, for example, how comfortable a passenger’s feet or hands would be in an aircraft or vehicle and determine cost/benefit to a design change in ECS or HVAC.

Total Thermal Solutions

ThermoAnalytics Human Thermal Module provides a full transient analysis of human comfort within complex asymmetrical environments. Because our software predicts a full multimode heat transfer solution, the mechanisms behind human comfort are also studied and new designs can be quickly performed for cost-benefit optimization analysis.

The Human Thermal Module accurately assigns thermal and mass resistances to each layer of clothing and connects it to the skin beneath. While the resistance of clothing to both heat transfer and diffusion of moisture can be defined by the user, a full library—including over 100 standard articles of clothing—is provided.

Custom Analysis

Our research engineers can deliver a fully positioned and clothed virtual dummy placed into your environment. User routines to tailor the comfort metrics or implement feedback control systems can also be delivered with full engineering reports and analyses.
