Iowa State University has
deployed a facilities
operations data
warehouse and business
information system that
currently includes 41
campus buildings. The
buildings integrate HVAC
operational data with
various combinations of
smoke systems, electric
meters and generator,
domestic water and
sewage, fire/emergency
systems, lighting
systems,
and space
planning
data.

These systems are integrated at both an
Administrative Services Bldg
operational level, through Johnson
Agronomy Hall
Controls, and at the information level,
Alumni Hall
using EnergyWitness from Interval Data

Iowa State collects data from
approximately 75,000 points across
campus. The system collects data every
15 minutes, 24x7, and is stored in the
data warehouse providing a permanent
historical record of operations. Although
it is a technical accomplishment to
collect complete operational data
without interfering with control systems
operation, the value to Iowa State is
realized through the many ways the
information is used.
There are over 100 users of the
information just within Facilities
Planning & Management. Different types
of users have unique information
views—engineers have a detailed,
systems/equipment view, while area
mechanics have a view that allows them
to review all systems they are
responsible for in a few minutes. Every
user gains significant insights. They all
see consistent information, and can
share insights and communicate more
effectively. This gives ISU a more
knowledgeable workforce that results in
major productivity and quality gains for
the school.
On top of the raw data are calculations
that provide ISU with additional levels
of operational and business knowledge
about the buildings. The system
Interval Data Systems, Inc.
104 Summer St.
calculates operating costs for every piece of
mechanical equipment, which is summarized at the
system and building levels. For each room (or space),
the system also measures comfort, combining
environmental readings into a single rating for that
space. This gives ISU a historical record of cost versus
comfort that is used to manage operations,
communicate with customers, and inform university
management.
The information available from the EnergyWitness
system is a catalyst in facilities’ continuing effort to
better serve the business needs of its customers and
reach its goal to be the best land grant institution in
the country.
