be the same. The first priority is to consider the process, but other important
issues, such as occupants, energy, environment, and corporate image, must
also be considered.
Energy is a key issue and is closely associated with the environment. Glo-
bal environmental issues must be addressed, where the energy chain from re-
sources to end users is of vital importance.
It is recognized that some countries are leaders in the area of scientific re-
search and experimental development. It is also known that Scandinavian
countries have been in the forefront of implementing leading-edge technology
for good environmental practice and energy-efficient plants in the 1980s and
1990s. The challenge is the implementation of the best industrial ventilation
technology and practice to all workplaces on a global basis.
The objectives of new innovations, procedures, systems, and equipment to
fulfill the end user's needs must be included as a part of the ongoing develop-
ment program. Significant advances in technology presented in this book are
target levels, systematic design methodology, indoor air quality strategies, and
control of flow in facilities. The objective is to make them work in practice
and to continue the development process.
It will be critical to update publications such as the Design Guide Book in
the industrial ventilation field on a regular basis. Never stop the developing
process; study, develop, and update everything, taking into account life-cycle
ecological issues.
When we compare industrial air technology (IAT) with comfort ventilation,
we can see that technologically our task is very challenging. To fulfill all the
needs of the end user is often impossible. If the IAQ is fulfilled, the amount of air
may be so large that draftiness is too high. We must also have the courage to say
what is possible and what is not. We also have to create tools to validate this.
The benefits of advanced industrial air technology are:
* Improved health of workers and reduced absenteeism as a result of
better IAQ
* Improved work satisfaction, higher productivity, and reduced
production failures as a result of improved indoor air quality
* Reduction in maintenance costs for the building fabrics, machinery, and
products
* Reduction in energy consumption as a result of improved usage
patterns and reduced air flow rates
* Increased awareness, and therefore improved selection, of new energy-
efficient systems in ventilation design, also leading to reduced energy
consumption
* Cleaner surroundings, and thus an improved image of the company,
resulting from improved systems and equipment
* Reduction in environmental pollution due to lower energy usage and
lower emissions to the surroundings
* Improved life cycle economy resulting from the use of high-level
industrial air technology systems and equipment
Field studies have revealed a significant potential for energy saving by
modern industrial air technology. For example, one study revealed great varia-
