This document discusses how IoT technologies can improve operational capacity in different functions of a building. It provides examples of how smart blinds, lighting systems, ventilation, air conditioning, and other appliances can save energy and resources when connected to building energy management systems. Sensors and intelligent controls are highlighted as helping to reduce energy costs by 30-60% by optimizing heating, cooling, and ventilation based on occupancy. Daylighting is also emphasized as the most energy efficient lighting option when possible.

- 10. Energy Efficiency – Demand side Ventilation (Commercial/Public Buildings) • Reduces energy cost (Heating/cooling/ventilation) for 30% to 60% depending on the specific object while increasing the personal comfort at the same rate. • For new buildings, this substantiallyreduces the amount of capitalinvestment and minimises the operating cost. • Smaller air ducts and virtually random placing of intake and discharge ducts allow for more freedom of architecture and utilisation.

- 16. Energy Efficiency – Demand side Smart Lighting Control System One of the most popular control systems chosen by homeowners is lighting control systems, which offers all benefits (free time, energy and money) plus the bonus of increased security for your home. If you’re considering a home automation lighting control system, you’ll first want to explore the varying levels of cost and difficulty available, from simple, standalone products that operate on a manually operated timer to turn lights on and off, to extremely sophisticated lighting control that integrates with a state-of-the-art whole-house automationsystem.
- 17. Energy Efficiency – Demand side Smart Lighting Control System For homeowners interested in a simple and efficient lighting control system, minus any complex bells and whistles, the option of a traditional manual timer-controlled lighting system will definitely be worth considering. Significantly cheaper than more advanced models that can be controlled and configured wirelessly or from anywhere on the planet via the internet, these basic systems plug directly into electrical outlets and feature simple clock timers that can be arranged to any desired length of time, that will then repeat on the 24-hour basis. In case your home takes a more integrated system, you can control all your home’s systems: security, HVAC, sprinklers, light, pet nourishing and almost anything else you may need-via your cellular network or the internet.
- 18. Energy Efficiency – Demand side Smart Lighting Control System Whichever home automation lighting control tier you decide to implement in your house, it is important to note one of the added advantages of automated lighting: security. Light systems–particularly for outdoor lighting can be easily integrated with security systems and frequently feature motion recognition as a deterrent for scammers. Even without advanced features, a simple light automation system that helps to keep your home regularly well-lit whether you’re home or not can operate as a deterrent alone.
- 19. Energy Efficiency – Demand side Smart Lighting Control System • The most energy-efficient measure to improve indoor light comfort is to use daylight as much as possible. – Daylightensures healthier indoor conditions, provides higher standards of visual comfort, makes rooms more comfortable, saves energy and money, reduces emissions and conservation natural resources. – It is desirable at all stages to find opportunities to maximize the use of daylight. • There is no need to save money in a way that compromises vision and normal living and working conditions due to low light. – In this way, the energy savings made do not make sense. • When furnishing a living space, the proper selection and arrangement of lamps is important as the choice of furniture or colors for walls.
- 20. Energy Efficiency – Demand side Smart Lighting Control System • The light efficiency of incandescent light bulbs 25 - 500W is 9 - 17 lm/W. – 5-10% of electricity is converted into light – The rest is converted to heat. • The work life is 1,000 hours. • They have a very good color spectrum and the color temperature ranges from 2,600 to 2,800 K.
