What is a BAS Control Panel?
A BAS Control Panel is a central component of a Building Automation System (BAS), which is used to monitor, control, and automate a building's mechanical and electrical systems such as HVAC (heating, ventilation, and air conditioning), lighting, security, fire systems, and more. The control panel acts as the nerve center that brings together field devices and communicates with a central BAS software platform. A typical BAS control panel includes the following components: Direct Digital Controllers (DDCs) are microprocessor-based devices. They receive input signals from sensors and send output signals to actuators and other devices. They execute programs that define how the systems should behave under various conditions. Converts incoming AC power to low-voltage DC power required by the controller and connected devices. Provide organized and secure connections for input/output wiring. Help in connecting sensors, actuators, and other field devices. Analog Inputs (AI) – e.g., temperature or humidity sensors. – e.g., temperature or humidity sensors. Digital Inputs (DI) – e.g., switch or contact closures. – e.g., switch or contact closures. Analog Outputs (AO) – e.g., variable frequency drives or modulating dampers. – e.g., variable frequency drives or modulating dampers. Digital Outputs (DO) – e.g., on/off controls for fans, pumps. Enable communication with other BAS devices and central monitoring systems. Common protocols: BACnet, Modbus, LonWorks, and KNX. Electrically operated switches used to control high-voltage equipment safely. Includes fuses, breakers, and surge protectors to safeguard internal components. A metal or plastic box that houses all components. May be rated for specific environmental conditions (e.g., NEMA 1, NEMA 4X). 1. Monitoring Collect data from sensors across the building. Provide real-time status updates for temperature, humidity, lighting levels, occupancy, etc. 2. Control Automatically adjust HVAC settings, lighting levels, and more based on programmed logic. 3. Scheduling Enable time-based control for lighting, HVAC, and other systems to improve energy efficiency. 4. Alarming and Notifications Trigger alerts for system failures, threshold breaches, or maintenance needs. 5. Trend Logging and Data Analysis Store historical data for energy reporting, fault diagnostics, and optimization. Energy Efficiency : Automates control for optimal energy use. : Automates control for optimal energy use. Comfort : Maintains consistent indoor conditions. : Maintains consistent indoor conditions. Cost Savings : Reduces operational costs via automation and predictive maintenance. : Reduces operational costs via automation and predictive maintenance. Scalability : Easy to integrate new systems or expand with additional zones. : Easy to integrate new systems or expand with additional zones. Remote Access: Enables building managers to monitor and control systems remotely. Label all wires and components clearly. Use structured and documented wiring layouts. Allow for future expansion with spare I/O points. Keep communication and power wiring separate to reduce interference. Perform routine inspections for dust, moisture, or loose connections. Commercial buildings : Offices, malls, hotels. : Offices, malls, hotels. Industrial facilities : Factories, warehouses. : Factories, warehouses. Educational institutions : Schools and universities. : Schools and universities. Healthcare: Hospitals and clinics. Panels should comply with standards like: UL 508A – for industrial control panels. NEC (National Electrical Code) ASHRAE standards for energy efficiency and control systems. BAS control panels are a vital part of modern building infrastructure. By serving as a centralized hub for automation and monitoring, they enhance building performance, reduce energy usage, and create comfortable, safe, and intelligent environments. TIME BUSINESS NEWS

Delhi CM empowers district committees to fast-track development
In a renewed push for decentralised governance and accelerated development, Delhi chief minister Rekha Gupta on Monday chaired a review meeting with all 11 district magistrates (DMs) and the newly reconstituted district development committees (DDCs) — grassroots monitoring bodies headed by MLAs — to streamline local infrastructure and public service delivery. Officials from the chief minister's office said the focus of the meeting was to ensure better coordination between elected representatives and administrative departments, and to enhance the implementation of government schemes and projects at the local level. Earlier this month, Gupta nominated 11 MLAs — eight from the BJP and three from the opposition Aam Aadmi Party (AAP) — as DDC chairpersons, directing all relevant government officials, including those from the revenue department, to mandatorily attend DDC meetings and provide full support to the committees. The move is aimed at reinvigorating district level governance and ensuring elected MLAs have a greater say in shaping developmental priorities within their constituencies. 'During the previous AAP government, the DDCs existed but they were largely inactive because the government was not focused on development,' said BJP MLA Ajay Mahawar, who now chairs the DDC for north-east Delhi. 'CM Gupta has empowered the DDCs and they will monitor the implementation of development works and government policies. It is a form of decentralisation of power, and the DDC will get the issues faced by the people fixed.' DDCs operate at the district level and are chaired by the MLA representing the area. The committees also include other MLAs from the district, the DM, and senior officials from departments such as the MCD, Delhi Jal Board, PWD, education, transport, and health. They are mandated to meet once every month to review progress on development works and address public grievances. In the third week of May, the CM reconstituted the DDCs, nominating BJP MLAs Ajay Mahawar (north-east), Gajendra Yadav (south), and Shikha Roy (New Delhi), among others. From AAP, Sanjeev Jha has been appointed chairperson of the Central district DDC. The DDCs are constituted annually, with chairpersons nominated by the chief minister for a term of one year. CM Gupta also issued strict instructions for administrative support to DDCs, stating that all designated officers from departments concerned must be present at DDC meetings. 'Any officer found absent without valid justification will face disciplinary action. Serving the people is our foremost duty, and the entire administrative machinery must be responsive, sensitive, and accountable,' she said. As reported by HT on May 24, Gupta also announced plans to establish 'mini-secretariats' in each of the city's 11 districts to consolidate key government services under one roof. She has directed all DMs to identify suitable land and submit proposals for the same. 'During the previous government, revenue offices were ignored—neither basic infrastructure was provided, nor were citizen services prioritised. Such negligence will no longer be tolerated. 'Mini secretariats' will be established in all districts of Delhi, where citizens will be able to access services such as revenue, public grievances, registration, certificates, and licences under one roof,' she said in a statement. 'These mini secretariats will serve as a major step toward providing swift and integrated public services at the local level.' To enhance citizen feedback and accountability, Gupta also instructed all DMs to install complaint boxes at DM, SDM, and sub-registrar offices. Residents will be able to submit handwritten complaints in these boxes, which will be monitored and evaluated directly by the Chief Minister's Office (CMO).
