Puerto Ricans Turn to Zimmetry Environmental for Answers to their Ventilation and IAQ Questions

SAN JUAN, Puerto Rico - Nov. 10, 2014 - PRLog -- It is not uncommon for indoor pollutants to accumulate to levels that can pose health and comfort issues when too little outdoor air enters a building. These may include mold, bacteria, tobacco smoke, chemicals such as volatile organic compounds (VOCs), radon, allergens, elevated levels of carbon dioxide and carbon monoxide, and other pollutants.

For those who live or work in a building with this type of problem, one approach to lowering the concentration of indoor air pollutants is by increasing the amount of outdoor air coming into a structure.

Outdoor air enters and leaves a building thru infiltration, natural ventilation and mechanical ventilation.  With infiltration, outdoor air flows into the building through openings, joints, and cracks in walls, floors and ceilings, and around windows and doors.  Air may also move out of the building in this manner and this is known as exfiltration. With natural ventilation, air moves through opened windows and doors. Air movement associated with infiltration and natural ventilation is caused by air temperature differences between indoors and outdoors and by wind. Finally, there are a number of mechanical ventilation devices, from exhaust fans that remove air from a single room, such as bathrooms and kitchens, to air handling systems that use fans and duct work to continuously remove indoor air and distribute filtered and conditioned outdoor air to strategic points throughout the building.

“When there is little infiltration, natural ventilation or mechanical ventilation, the air exchange rate is low and pollutant levels will often rise,” said Harry Pena, President of Zimmetry Environmental. “Some residential heating and cooling systems, including some forced air heating systems, do not mechanically bring fresh air into the house. At Zimmetry, our indoor air quality experts can identify indoor pollutants, ventilation issues and provide recommendations on ways to resolve any problems that may be found in residential, commercial and institutional buildings.”
