This document discusses building automation standards and integration. It covers various communication protocols including BACnet, KNX, DALI, EnOcean, and others. It explains the benefits of standardization such as making products more compatible and ensuring consistent quality. Standardization increases interoperability between vendors. The document also discusses various standards organizations and committees involved in building automation standards like CEN/TC247, ASHRAE, and BTL. Siemens' involvement with these standards and various energy efficiency initiatives is also summarized.

Standardization Benefits
Benefits
• Make the product users be sure that the promised characteristics and
quality are indeed delivered.
• Make the end products have consistent quality and that any
conclusions made are comparable with all other equivalent items in
the same class.
• Standards increase compatibility and interoperability between product
Language definition
To make things of the same type all have the same basic features.
Technical standardization
Standardization is a framework of agreements to which all relevant
parties in an industry or organization must adhere to ensure that all
processes associated with the creation of a good or performance of a
service are performed within set guidelines.

CEN/TC247
CEN / TC247 develops European and international standards for
building automation, controls and building management (BACS), for
instance:
• Product standards for electronic control equipment in the field of
HVAC applications (e.g. EN 15500)
• Standardization of BACS1 functions (EN ISO 16484-3)
• Open data communication protocols for BACS (e.g. EN ISO 16484-5)
• Project specification and implementation (EN ISO 16484-1)
• Energy performance of BAC functions (EN 15232)
.

ASHRAE
13-2015: The guidance for design, document, and specify building
automation systems (BASs).
• A careful review of suppliers offering BAS should be made before
proceeding with creation the system. BAS products changes more
rapidly than HVAC industry.
• Energy conservation and system optimization (e.g. optimum
start/stop, demand limiting, VAV..etc)- ASHRAE/IES 90.1 &
ASHRAE/USGBC/IES189.1 cannot realistically be accomplished
using pneumatic or electric controls.
• Restrictions of use for BAS – UL, c UL restrictions
135-2016: BACnet, the data communication protocol for building
automation and control networks.
.
BASs: Building automation systems. VAV: Variable air volume.

Highlights for BTL list
BTL: BACnet Testing laboratories.
• Devices with BTL mark are tested by a recognized BACnet Testing
Laboratory.
• BTL certifies the associated BACnet objects and services of the
device profile, including encoding and decoding of data.

EU.BAC
• Siemens took the initiative and the members include renowned
international manufacturers of products and systems in the home and
building automation and control sector.
• Products and systems with eu.bac certification display a guaranteed
state and quality assurance.
• eu.bac Cert guarantees users a high level of energy efficiency

GreenBuilding
• Siemens is a partner of the GreenBuilding initiative by the European
Commission, with a goal of implementing cost-effective, energy
efficiency potential in buildings. As a signatory to this initiative,
Siemens BT must ensure that its customers can achieve a minimum
energy efficiency of at least 25% in their building infrastructures..

LEED
• For the past five years, Siemens has also been a member of LEED
(Leadership in Energy and Environmental Design) – a US initiative
similar to GreenBuildings. LEED continues as a recognized and
respected certification, where independent third-parties certify that
the building project in question is environmentally compatible and
profitable and represents a healthy location for work and living.

Clinton Foundation
• Headed by former US president Bill Clinton, the initiative cooperates
with larger municipal governments and international companies to
develop and implement various activities to reduce greenhouse
gases. Specifically, the initiative informs large cities on measures
available to optimize energy efficiency in buildings with outloss of
comfort for the residents and users. Here again, Siemens has taken
the lead in conducting energy audits, building renovation and
guaranteed savings from such projects.

Reference to ASHRAE
Section 4: DIRECT DIGITAL CONTROL (DDC) OVERVIEW
• A BAS is often necessary to meet specifications of sustainability
guidelines such as LEED™, Green Globes™, and Go Green™. The
BAS allows the user to commission the systems to meet these
sustainability guidelines. A BAS will also monitor the various systems
to ensure compliance to these standards so that energy savings are
maintained over the long term.
