Glare, solar heat gain, and direct sunlight diminish the
comfort of interior spaces, making it more difficult for people to perform
basic work functions. A 2003 study showed that the greater the glare potential
from primary view windows, the greater the impact on office worker performance.
All other things being equal, productivity decreased by 15 to 21 percent.

While specifying a shading system is a key element in
addressing these concerns, the shades are only part of the solution.
Motorization adds efficiency and ease of use, but adding automation truly
allows you to get the most out of a shading system.

Adding automation can seem like a scary, complicated step,
but it doesn’t have to be. There is a range of solutions from basic sensors to
full building control, depending on each individual project’s needs and goals.

Draper® separates automated glare control into three categories.
None of our solutions require a PC or external software—setup is accomplished
through integrated human-machine interface controls.

Basic sensor-based control.
Technically, this category isn’t really automation. It is a mostly reactive approach that mimics automation, but it is a good first step for small projects or tight budgets.

This approach combines the IntelliFlex®
I/O Sensor/Schedule Interface (SSI) and up to four sensors. Built-in features
support brightness, wind, and precipitation sensors, as well as pyranometers,
in up to four different zones. You can also schedule override events that can
be configured to run on any combination of days of the week.

Simple automated glare control.
Some areas, such as atriums, reception and waiting areas, wellness center, and school gathering areas require a more automated solution. This approach is also helpful when shades on an entire floor of an office or mixed-use building need to be automated.

Our solution is the IntelliFlex I/O Sensor/Schedule
Interface + (SSI+) with Automated Glare Control. The SSI+ utilizes a model of the
building’s orientation and geographic location to calculate where shades should
be and adjusts them accordingly. This allows us to control solar depth
penetration—how much sunlight you want to enter the room.

In addition, you can integrate up to four sensors—by
third-party or Draper®—and schedule up to eight override events to run on any
combination of days of the week.

Full automated glare control.
We use a complete automation solution when shades throughout multiple floors or an entire building need to be controlled.

As with the SSI+, we are looking to limit the solar depth
penetration. But for whole building control, we offer the IntelliFlex Central
Network Controller (CNC). The CNC uses an algorithm-based software to determine
the sun’s location in the sky. By using a formula that includes building
coordinates and time of day/year, the software automatically moves the shades
to a position that is based on the parameters set up for the solar depth
penetration for each project. For example, if we set the standard at 3 feet,
the automation system will adjust the shades throughout the day so more than
that predetermined amount of sunlight penetration never occurs.

The CNC acts as a router between control and IP networks. It allows communication between networks and IP integration with other systems for whole building automation. In addition to automated glare control, the CNC allows the logging of shade movements, sensor readings, and user overrides.
