EcoFresh Educational & Recreational Areas - Case Studies

Sham Shiu Po Primary School, Kowloon, Hong Kong is totally airconditioned.

Recognizing the need for maintaining IAQ in the class rooms, the project consultant specified Ecofresh ERVs (Energy Recovery Ventilators) to be installed in every classroom. We have already shipped out and installed RO noc ERVs to Hong Kong.

Why is lAQ important in School?
Indoor Air problems can be subtle and do not always produce easily immediately recognized impact on health or well-being of people.
Children are especially susceptible to long term effects from air pollution. Therefore, air quality in schools is of particular concern. Proper maintenance of indoor air is more than a "quality" issue; it includes safety and good management of our investment in the students, staff, and facilities.

IT Complexes mushroom as Software booms!

With the software boom, IT complexes are mushrooming to provide the software developers the "best quality work environ'. These "state-of-the-art" complexes are totally air conditioned. Software Professionals spend most of their lives inside these conditioned "quality" spaces While these spaces are comfortable, the may not be completely healthy. The Indoor Air Quality (IAQ) in a conditioned space is generally poor, as not enough importance is given to ventilation.

The closed and conditioned "in''vironmen of such complexes provide the perfect environment for growth of microscopic airborne contaminants responsible for poor Indoor Air Quality (IAQ).

Indoor air problems can be subtle and do not always produce easily recognized impacts on health and the well being of people.
Air in Conditioned Spaces can be more Polluted than outdoor air. Airconditioning is a major factor affecting Indoor Air Quality (IAQ). Majority of airconditioning systems are designed with very little or almost no provision for fresh air, as fresh air means, more kilowatts of conditioning and thus higher energy cost.

Inadequate ventilation, coupled with re-circulation of stale , results in poor Indoor Air Quality (IAQ), due to a buildup pf pollutants like cigarette smoke, carbon-dioxide, mold, bacteria, viruses and potentially dangerous chemical emitted from copying machines, furniture, carpets and paint.

The high concentration of pollutants in indoor conditioned space causes a phenomenon known as the "Sick Building Syndrome" (SBS). SBS is a cluster of complex symptoms that include irritation of the eyes, blocked nose and throat, headaches, dizziness, lethargy, fatigue, irritation, wheezing, sinus, congestion, dry skin rash and nausea.

These symptoms are generally work related, that is, they begin shortly after the person enters the building disappear within a few hours, after he leaves it. A more and long term effect on health may arise due to a continued exposure and lead to "Building Related Illness (BRI)".

The solution to Pollution is Dilution

Increased ventilation results in improved indoor environment but adds to the first and operating cost of airconditioning systems.

Proper balance between energy efficiency and ventilation of acceptable Indoor Air Quality (IAQ) has thus, become a critical problem for designers as well as building owners,operators and maintenance personnel.
