A healthy indoor
environment is one in which the surroundings contribute to
productivity, comfort, and a sense of health and well being. Failure
to respond promptly and effectively to IAQ problems leaves building
owners and facility managers vulnerable to unnecessary risks such as
building-related illness, reduced productivity, accelerated building
deterioration, strained relations between employers and employees
or landlords and tenants, negative publicity, and potential
liability problems.
Provision of good air
quality requires conscientious effort by both building staff and
occupants. The commitment to address IAQ problems starts with the
building owner or facility manager, the person who has an overview
of the organization, sets policy, and assigns staff
responsibilities. You have the authority to see that an IAQ policy
is articulated and carried out, the ability to identify staff with
skills that enable them to react promptly and effectively to
complaints, and the incentive to initiate a program that will
prevent indoor air problems in the future. As you decide how best
to respond to the challenge of preventing and resolving indoor air
quality problems in your building, it will be helpful to keep in
mind the following thoughts:
It is
important to establish a process that encourages an active exchange
of information.
Without an open
communications policy, an atmosphere of distrust may be created that
complicates your efforts to diagnose and correct problems.
Facility staff are in a position to notice
malfunctioning equipment or accidental events that could produce
indoor air quality problems. They can play a critical
role in identifying problem situations and averting IAQ crises. On
the other hand, if staff are not aware of IAQ issues, their
activities can also create indoor air quality problems.
Facility staff are often instructed to keep
energy costs to a minimum. Changes in building operation
intended to save energy may create even greater problems (for
example, by reducing the flow of outdoor ventilation air without
taking action to maintain the quality of the re-circulated air).
The correction of IAQ problems may result in reduced energy use due
to the efficiency associated with a cleaner, and better controlled
heating, ventilation, and air conditioning (HVAC) system. The
energy needed to condition and distribute ventilation air is only a
small part of total building energy consumption and is far
overshadowed by other operating costs (such as personnel).
Attempting to limit operating costs by reducing ventilation can be a
false economy, if it leads to problems such as increased occupant
complaints, reduced productivity, and absenteeism.
Every complaint merits a response.
Many issues are not
difficult to correct and can be solved with in-house expertise.
However, gathering relevant information about the problem and
identifying appropriate corrective actions is likely to require a
coordinated effort by people with a variety of skills.
An indoor air quality problem may be the
direct or indirect result of an apparently minor modification.
Actions such as the placement of interior room dividers, the
introduction of new office equipment, and personal activities such
as cooking can have an impact on indoor air quality. Communication
between building management and building occupants regarding their
respective responsibilities is a critical element in the management
of indoor air quality.
Indoor air quality in a large building is the
product of multiple influences, and attempts to bring problems under
control do not always produce the expected result. Some
indoor air quality problems are complex and may require the
assistance of outside professionals. When contracting for services,
you need to be an informed client to avoid unnecessary costs and
delays in solving the problem. |
