Key Elements in Intelligent Buildings

The concept of an ‘Intelligent Building’ encompasses various automation systems for Building Control, Office, Communications, Security and Fire. An IB project generally covers three key elements.

  • Communications Network and Office Automation.
  • Building Management System.
  • Integrated Services Infrastructure.

Communications Network & Office Automation System

The System includes office administration, Property Management, and Business Intelligence Systems that reduce heavy workloads and human error to enhance efficiency, quality and the working environment as a whole. Voice, Data, Video and Multimedia Information Services, such as Video Conferencing, Email and Electronic Data Exchange, are provided via the building’s high-speed backbone network to the benefit of each

Building Management System (BMS)

Building Management System provides automatic monitoring, interaction and management for electricity, ventilation, water supply, security and fire control to the building. BMS manages the following systems: Building
Automation System (BAS) Security Automation System (SAS) & Fire Automation System (FAS):

Building Automation System (BAS)

The Building Automation System centralises the remote monitoring and control of all building facilities – including electricity, lighting, plumbing, ventilation and air-conditioning, water supply and drainage and environmental control systems – at a single control center. Seamless monitoring of all these systems ensures a reliable working or living environment for tenants as well as optimised human resources allocation for the Property Manager.

Security Automation System (SAS)

Security Automation System is critical for providing a secure environment and protecting the safety of tenants. Elements include: Anti-theft Security and Alarm System , Electronic Control System, Access Control System, Closed-Circuit TV Surveillance System.

Fire Automation System (FAS)

The Fire Automation System is supported by independent network and cabling systems to ensure operation continues nonstop, even during an emergency. When linked to the building’s centralised control room, a second level of monitoring is provided; and in case of fire, various systems can interact directly to optimise all necessary building facilities.

ELV Integration

For many years, voice and data systems were cabled separately. Now it is standard practice to use a common platform for both of these systems. Like the Voice and Data Systems of the past, the traditional construction process separately installs each of the BMS disciplines under various divisions of a specification.

This means that multiple cabling systems and pathways are installed during the various stages of construction, which establishes one of the primary reasons for ELV Systems Integration i.e. (Integrated Cabling and pathways instead of individual systems). Also, the BMS vendors have now started to use Data Networking and LAN architectures which allow them to communicate over a Standard Ethernet LAN using the same TCP / IP protocol used by computers.

For UPnP™ Device Architecture V 1.0 Status: Standardized DCP Date: May 13th, 2003

This Standardized DCP has been adopted as a Standardized DCP by the Steering Committee of the UPnP Forum, pursuant to Section 2.1(c)(ii) of the UPnP Membership Agreement. UPnP Forum Members have rights and licenses defined by Section 3 of the UPnP Membership Agreement to use and reproduce the Standardized DCP in UPnP Compliant Devices. All such use is subject to all of the provisions of the UPnP Membership Agreement.

Overview and Scope

The HVAC_ZoneThermostat is intended to be a sub device of the HVAC_System device. Any number of HVAC_ZoneThermostats may be included in the system device. HVAC_ZoneThermostat is a zone level controller for heating and/or cooling. It provides the following functionality:

The ability to set or get zone level operating and fan modes. Temperature in the zone Zone level Heating and/or cooling temperature setpoints Optional fan speed control Optional zone level daily schedule for events and heating and cooling setpoints.

Honeywell Plastics Snap-Fit Design Manual

Why use snap-fits? This chapter will give you a thumbnail sketch of the benefits of snap-fits and the materials used to make them. Snap-fits are the simplest, quickest and most costeffective method of assembling two parts. When designed properly, parts with snap-fits can be assembled and disassembled numerous times without any adverse effect on the assembly.

Snap-fits are also the most environmentally friendly form of assembly because of their ease of disassembly, making components of different materials easy to recycle. Although snap-fits can be designed with many materials, the ideal material is thermoplastic because of its high flexibility and its ability to be easily and inexpensively molded into complex geometries. Other advantages include its relatively high elongation, low coefficient of friction, and sufficient strength and rigidity to meet the requirements of most applications.

The designer should be aware that the assembly may have some “play”due to tolerance stack-up of the two mating parts. Some snap-fits can also increase the cost of an injection molding tool due to the need for slides in the mold. An experienced designer can often eliminate the need for slides by adding a slot in the wall directly below the undercut or by placing the snaps on the edge of the part, so they face outward.
