Intelligent Building Control

in a Unified Front End


WebLink Custom

User Interfaces

Intelligent Building Interfaces

Networked monitoring
and control through
single, unified interface

Update control logic,

access codes, schedules

over WWW or dialup

Users can schedule
after
-
hours usage,

self
-
manage logins
and door card access

Authorized access so

visibility and control

appropriate to user role

Intelligent Building Systems

Odyssey System


CCTV + DVR and Card Access
integrated into unified ASI WebLink front end

Automated control of HVAC, Lighting, Central
Plant etc. Integrated energy management, demand
control functionality

ASI WebLink


OPC
-
client front end with 3D
graphics, ODBC queries, CSV export, SSL support

ZoneDial


interface to schedule and track energy
use; with accounting, invoicing, self
-
administration

Intelligent Building Interfaces

Interoperability between building control systems
allows for “best
-
of
-
breed” solutions

Web technologies for data, content presentation
and secure interaction are progressing

Efficiencies, convenience and savings available
with a unified web accessible front end for all
users and stakeholders in an intelligent building

Interoperability Support

Modbus RTU


an open protocol for
control of variable
-
frequency drives,
sensors, and other electrical devices

OPC


set of standards for device
interoperability, widely adopted by
industrial automation PLC makers

BACnet® is a registered trademark of ASHRAE

BACnet


ASHRAE's open protocol
for building automation applications

Interoperability Options

ASIC/2 configurable controllers can act as
Modbus RTU Master

WebLink OPC
-
client front end integrates
CCTV/DVR output via web server

ASI Controls provides BACnet interfaces to
interoperate with BACnet systems

WebLink supports iFrames and Javascript

Building Users

Calibrated access and control by user type

Engineering needs full visibility and control

Tenants need local visibility, pinpoint control

Owners/Managers need full visibility with
limited control

Service Techs may need local visibility and
limited control

ASI ZoneDial

For energy optimization HVAC, lighting is
on during day, setback at night. Users can
request and pay for after
-
hours services

ZoneDial is a web interface for requesting
HVAC, lights, and other building services

Suited for scheduling leased office space,
college classrooms, event spaces, etc.

ASI ZoneDial

Property managers determine occupancy
schedule, billing rates, holidays, etc.
Create formatted tenant invoices on web

Tenants can schedule service, curtail
current service, self
-
administer user
logins, preview or review billings, usage

Typical ZoneDial Scenario

Tenant uses ZoneDial to
schedule after
-
hours lights

1

2

ZoneDial activates the

zone at the requested time

Typical ZoneDial Scenario

ZoneDial deactivates zone
after requested interval

3

4

Building manager bills tenant
for after
-
hours energy use

ASI ZoneDial

ZoneDial can support other types of service
requests, i.e. change light bulb, resend invoice

Owners may amortize additional costs of
providing services for enhanced asset revenue
recovery

Tenants can “be in control”, accountably

WebLink/Odyssey System

Integrates DVR/CCTV

Integrates to access
control systems

View demand, power
quality in real time

Automated notification
of alarms and events

WebLink/Odyssey System

Manage network of
facilities over internet

One web server hosts
all network locations

User access and level
of control is restricted
by login and role

Retail Network Case Study

Chain of 400+ stores in United States,
107 of which have Odyssey Systems

Stores were already networked to provide
point
-
of
-
sale data, process credit cards

Project requirements included reducing
energy use and inventory losses. Wanted
a single web interface into all systems,
with extensive trending capabilities

Retail Network Case Study

Odyssey System uses WebLink as single
front end for security, HVAC, and EMS

A single instance of WebLink running at
HQ provides a front end to all the stores

HQ extracts data from WebLink and other
Enterprise databases with ODBC queries

WebLink reports exported as CSV
-
data

Case Study


Role
-
based Control

Store managers can view data for their
store only, with limited override capability

Regional managers see their stores, can
combine store data in graphs and reports

HQ can access any location. Reporting
and graphing incorporates trend data
from a store, sub
-
set, or whole network

Case Study


Service Access

Controls contractor can access the
control system in any store over Internet

Contractor can remotely reprogram the
controller at any site

“Netcasting” feature enables changes
made at 1 site to automatically propagate
to any number of other stores. E.g.
extended hours of operation at Christmas

Case Study
-

EMS

Control system tied into security alarm
system for occupancy scheduling

Email alerts notify managers of abnormal
energy use, with an escalated recipient
list if the event goes unacknowledged

Demand limits cap peak demand

Photocells help control system harvest
daylight indoors, optimize exterior lighting

Case Study
-

Security

If security alarm trips, control system fully
illuminates store to enhance CCTV image

Email alerts notify management if alarm
system is not armed at closing time

Managers can remotely Arm/Disarm
security system, add/remove user codes

Case Study
-

Results

Store management is projecting 10 year
savings of $10 million

ROI of 40% on 107 stores in project

Staff feel they are “more in control”

Energy savings range from 15% to 40%

Inventory shrinkage reduced to 1.6%

Scalable Architecture

Ethernet options with
USB
-
, Direct
-
, & Router

Interoperability with
Modbus, OPC, BACnet

Unified interface options
for automation systems

One WebLink instance
hosts all network sites

Remote Monitoring & Control

Connect to any
networked or
dialup facility

Automated alarm
event notifications

Use “Netcasting” to easily propagate

configuration changes to a network or sub
-
net

Report and Graph trended
data, export as CSV data

Control R/W by login, role

Supports ODBC queries,
runs on ODBC
