What is indoor environmental ergonomics?

What is radiant based HVAC?

 

HVAC

HVAC is the acronym for Heating, Ventilation and Air Conditioning.

Most people confuse HVAC with comfort when in fact HVAC has very little to do with comfort. Why?

Heating a space is easy and can be accomplished easily and cheaply with a hot air furnace. But as many North Americans experience, far too often we can be in a heated space and still be uncomfortable.

Ventilation whilst important for indoor air quality is not directly related to thermal comfort. Why? Because we can be simultaneously comfortable and  inhaling deadly carbon monoxide fumes. 

Air Conditioning is not 'cooling'. A/C is conditioning the air which means it could be about humidity control, air speed, filtration and temperature.

Our message is:

Heating a space does not make you comfortable nor does it control the quantity of moisture in the air. See Myth #9 in Radiant Mythology.

You can be comfortable in an environment with poor air quality.

Conditioned air can be cool-dry and dirty or hot-moist and clean...ideally it should be anything but the above.

When discussing HVAC with your builder or mechanical contractor please understand the folks designing your interior environment very rarely study the relationship between architecture, mechanical systems and human physiology. Unfortunately that's our North American system.

Fortunately good information on indoor environmental quality is readily available, is based on fact, is desireable, specifiable and obtainable in your home or cottage - Click Here To Learn More.
