HVAC Design Criteria 14 File Number

HVAC Design Criteria HVAC systems can interface to Building Automation System (BAS) to allow the building owners to have more control over the heating or cooling units. The building owner can monitor the system and respond to alarms generated by the system from local or remote locations. The system can be scheduled for occupancy or the configuration can be changed from the BAS. Sometimes the BAS is directly controlling the HVAC components. Depending on the BAS different interfaces can be used Typical Architecture for HVAC Disadvantage of Standalone System 1. Centralized Control is not Possible. Today, there also dedicated gateways that connect advanced VRV / VRF and Split HVAC Systems with Home Automation and BMS (Building Management Systems) controllers for centralized control and monitoring, obviating the need to purchase more complex and expensive HVAC systems. In addition, such gateway solutions are capable of providing remote control operation of all HVAC indoor units over the internet incorporating a simple and friendly user interface 2. Alarms cannot be monitored. 3. Optimization of the system is not possible. 4. Cloud based cannot be implement. 5. New Strategies using Energy Management Software's for increasing the building efficiency cannot implement. 15 File Number

Cyber Security 30 File Number

What is Cyber Security? • It is referred as Information Technology Security • Focusing on protecting: • Computers • Networks • Programs and Data • From unintended or unauthorized access, change or destruction. 31 File Number

Why is Cyber Security Important? • Who uses the Internet? • Big Businesses • Financial Institutions • Hospitals • Governments • Military • What do they do and what do they do with the information? • Collect, process and store confidential information on computers • Transmit that data across networks to other computers • What do they/we need to do? Protect sensitive business and personal information. 32 File Number

How On-line attacks damage consumer trust? • Customers are making more transactions online and trust in a brand is paramount • What happens if your information ends up in the wrong hands? • Would you shop on-line with them again? • The challenge is being able to identify the risks and take action • Currently, brand owners only know about approximately 10% of the threats. 33 File Number

Cyber Attacks Adobe Systems Inc said it was the victim of sophisticated cyber attacks on its networks by hackers who accessed data belonging to millions of customers along with the source code to some of its popular software titles Microsoft has revealed it had its computer system hacked Royal Bank of Scotland has said its websites fell victim to a cyber attack after customers were unable to access online banking UK retailer Lakeland revealed it was forced the firm to reset all customer passwords as a precaution Nat. West victim of cyber attack after site crashes for the second time The data breach of Sony's Play. Station Network resulted from a "very carefully planned, very professional, highly sophisticated criminal cyber attack designed to steal personal and credit card information for illegal purposes” Facebook and technology giant Apple have also admitted to being hacked. 34 File Number

IT Networking basic - VLAN 36 File Number

Understanding Basic IP Addressing An IP address would look something like this 128. 1. 73. 21 and is made up of two distinct parts. Network Address 128. 1 The first part of the address, 128. 1 is the Network Address, this connects us to the correct network (like the area code). The second part of the IP address, 73. 21 is called the Host address and this connects us to the correct device (or Host). Host Address 73. 21 The numbers used to make up an IP address are normally between 0 and 254 (8 bit Logic). 37 File Number

Understanding Basic IP Addressing - Classes Many different sizes of network are needed in the IT world, from small home networks that maybe have 3 or 4 devices sharing an internet connection to huge multinational companies, with thousands of PCs in just one building. Network Address 128. 1 To account for varying size of networks, the IP address can be formatted in a number of different ways. In the previous example, we split the IP address in the middle. Network Address 128. 1 Host Address 73. 21 This is referred to as a Class B Network, we can have 16, 384 networks each with 65, 534 addresses. 38 File Number

Understanding Basic IP Addressing – Subnet Mask Wherever there is an IP address, there is something called a Subnet Mask and it’s this that shows where the IP address is divided. Network Address 126. The numbers used are normally only 255 or 0. The subnet mask is compared with the IP address. A subnet mask may look like this 255. 0. 0. 0 IP Address 126. 168. 73. 21 Subnet mask 255. 0. 0. 0 Host Address 168. 73. 21 Where the subnet mask has 255, it indicates the Network part of the IP address IP Address 128. 168. 73. 21 Subnet mask 225. 255. 0. 0 39 File Number
