Verdiem Surveyor software provides the power management for ICT devices, helping
enable energy consumption control over approximately 600 PCs, 120 Cisco IP phones,
150 Cisco wireless access points, a video surveillance system with over 75 IP cameras,
and 60 Cisco Catalyst switches, with the potential for adding the interactive white boards
and projectors in classrooms. Within the solution, devices are grouped into several
categories, and management can select devices by any category to which they have been
assigned. Each device is identified by its location, type of device, and by department or type
of use. This arrangement allows granular development of policies to turn groups of devices
on and off for better energy management.

3. Surveyor provides an easy-to-use, web-based console for a unified view of all the
networked devices. It generates energy management and IT efficiency reports that dive
down into data based on group, location, and other categories of interest. The software
also assists with a common need for the schools’ computers to receive software updates
overnight. For these situations, Surveyor integrates with Microsoft System Center and other
client management solutions, and Verdiem’s patented Wake-on-WAN capability provides a
network-friendly approach to reliably wake up computers for the updates and then turning
them off upon completion.
At Rainha D. Amélia School, a Schneider Electric building management system (BMS)
provides a dashboard to monitor and control the HVAC, lighting, and access control
systems. The BMS controllers integrate with room lighting systems and occupancy
detectors as well as key components of the HVAC system, including variable air volume
(VAV) air handlers, fan coil units (FCUs), heat pumps, and chilled beams. The open
architecture of the BMS allows cohesive integration with Cisco EnergyWise and
Verdiem Surveyor software.
In all three schools, the primary technique for network-managed energy savings consists
of scheduling the operation of HVAC, lighting, and ICT equipment to coincide with the
occupancy plan for the buildings. Core school hours and official school breaks are quite
similar at all three schools, but exam periods and night courses, as well as public usage
of facilities outside of school hours, can be quite different at each school. Despite the fact
that the details of device grouping and scheduling vary from school to school, the pilot
has proven an effective venue in which to test different approaches.
For example, most of the phones can be shut off at night, while emergency phones remain
active. Additionally, some devices are controlled based on occupancy or current use, such
as PCs running a specific application or used for specific services, such as backups. In
addition, so as not to interrupt work in progress by individual users, PC users receive pop-
up messages that allow them to override or delay an impending shut-down command from
the central system.
Policies can also be applied to centrally turn off HVAC and lighting systems in all of the
buildings outside of occupancy hours. As a result, room temperatures can be maintained
at a comfortable level while student, staff, or community groups are present, and be set
to conserve power after hours. The lighting system controls provide automatic means to
optimize lighting based on three main variables: time, intensity, and occupancy. Because
lighting systems can create a significant heat load for a building, optimized lighting policies
can reduce the cooling load on the HVAC system for overall lower energy use.
The pilot included the launch of Web 2.0 tools to connect the schools and promote
engagement around energy conservation among students, teachers, and staff. Interactive
displays with real-time data, benchmarks, and carbon footprint calculators encourage
greater awareness and energy-saving behaviors among the school population. The use
of project results data as educational material also reinforces the fact that energy savings
promote sustainable school communities.
Results
Reductions in energy use by HVAC, lighting systems, and ICT devices at the schools are
expected to provide significant cost savings, which can then be applied by the schools
to capital improvements, teacher training, and other learning initiatives in concert with
its mission.

and some have expressed interest in pursuing careers in environmental sciences.
“This Cisco-Schneider Electric-Verdiem initiative delivers greater energy efficiency and
important cost savings for Portugal’s schools. At the same time, it fosters “green” individual
behaviors and organizational policies that help increase the momentum for sustainability on
a global scale,” says Parque Escolar.
