The Hartman Company Newsletter

Issue: June 2003
Topic: New Industry Opportunities

Dear Hartman Company Newsletter subscriber,

The results of recent projects confirm new network enabled control 
technologies offer enormous opportunities to those in the industry who are 
willing to change their perspective from the century old concepts that have 
guided and continue to guide building HVAC system design and operations.

Without raising first costs it is now possible to build and operate 
commercial building HVAC systems that consume about 50% of the electricity 
of fully optimized conventional systems and at the same time incorporate 
simpler system configurations and simpler operations. These benefits are 
now being demonstrated in the early projects we have completed that have 
been designed around the new control technology called "demand based control"

Although demand based control offers a sound and straightforward path to 
improving energy efficiency and comfort in buildings, it is by no means 
universally accepted by the industry at this time. Many manufacturers, 
designers, and building operators appear willing to continue employing 
older technologies in their work. For the first time in a long while, this 
creates in our industry a true opportunity for differentiation and a 
potential competitive advantage for those who are willing to incorporate 
and support more advanced control technologies in our products, designs, 
and building operations.

To get a better idea of the potential benefits that demand based control 
offers designers and manufacturers, and how this technology is applied most 
effectively, we have assembled the following elements from our firm's 
resource database:

1. An on-line essay written by  Mr. Hartman for automatedbuildings.com 
outlines the two most critical problems in our industry and how network 
enable demand based control can provide improvements that are orders of 
magnitude beyond the performance of current technologies. This essay can be 
found at:

2. A recent HPAC Engineering Magazine Article Mr. Hartman wrote on 
ultra-efficient building comfort cooling that describes some of the 
features of demand based control and outlines a case study of this exciting 
new technology. This article is available at:

3. An article Mr. Hartman wrote a few years ago that discusses the critical 
issue of comfort control in commercial buildings. This article shows why 
maintaining suitable comfort requires some capacity for individual control 
which is now becoming more straightforward to apply. This article can be 
found at:

Finally, an important notice. The Hartman Company is moving. This fall we 
will have a new address and new phone numbers. We will alert you about 
these new contact points in a later newletter. This information will also 
be available on our Website. Our website and email addresses will remain 
the same.
