Ensuring thermal comfort in your home or building

Schedule A Call

Thermal comfort is a condition where an individual(s) express the satisfaction or dissatisfaction within the thermal environment. The thermal environment is those characteristics of the environment which can result in a person’s thermal discomfort response. In terms of the individual’s senses, thermal comfort or discomfort is a sensation of hot, warm, slightly warmer, neutral, slightly cooler, cool and cold.

Relative humidity and ambient temperature become the most critical factors for maintaining satisfactory thermal comfort. Unfortunately, however, temperature preferences vary greatly among individuals and there is no one temperature that can satisfy everyone. Therefore, maintaining consistent thermal conditions in the environment (office/home) is very important.

We are available to assist our clients in understanding the cause(s) associated with thermal discomfort, we also have the required experience and equipment to evaluate complex thermal issues in residential and commercial settings.

Heat Gain / Heat Loss Analysis

A heat gain/heat loss analysis is a process by which the amount of heat entering (or exiting) a building is quantified. The reason that the total heat entering (or exiting) a building must be determined is to properly size the heating/cooling equipment for the building.

A building’s HVAC (Heating, Ventilating & Air Conditioning) system has two main functions: controlling indoor temperature and controlling indoor moisture levels. A properly sized HVAC system will maintain indoor temperature and moisture levels at a given design condition. HVAC systems that are too small for a given application will have trouble maintaining indoor setpoint temperatures during peak load times. HVAC systems that are too large for a given application will have trouble maintaining indoor moisture levels within an acceptable range. Both cases can lead to different forms of occupant thermal discomfort.

Enviro Team North America has the ability to assess heat gain/heat loss calculations on both residential and commercial buildings to assist our clients on a variety of projects.
