Here's how you can improve energy efficiency in buildings using new technology.

I believe that with smart sensors and AI , energy management and saving will be more easy and accurate. Even estimation and energy forecast will be more accurate.

Do not make everything smart. Sometimes stupid sensors are more reliable and cheaper. In any case: you cannot change what you do not measure. Measure everything you want to improve. Essential sensors are temperature, power usage, gas usage, district heating flow, and heat delivery. Then it is extremely helpful to know more about your building. Like the number of people in the builing, open/close sate of doors, windows, and other equipment. The smart part is not the sensor it its the software in a centralized ( cloud ) place.

Integrated IoT will enable you to make a difference. Make sure the products and software you choose is open, reliable (need to run without care for 5 to 10 years), and bi-directional. Meaning: not only measure the state of the building heating system, also control it. Integrate all operations in one platform and then optimize for your goal: Costs, energy efficiency, or comfort.

In my experience, Lagos office buildings often guzzle energy, leaving companies with sky-high bills. Imagine turning the tide with IoT. Picture tiny sensors monitoring every flicker of electricity and puff of air conditioning, sending data to a central dashboard. You'd find lights left on all night and AC blasting in empty rooms. To turn this around, you can install smart thermostats that learn office rhythms and intelligent lighting systems that adjust to occupancy or dive into IoT energy harvesting, where sensors draw power from sunlight and foot traffic. When these systems work together, they cut energy use, create comfort, and can make your building or office a sustainability star in Lagos.

The strategic adoption of IoT (Internet of Things) technology significantly enhances energy management. By automating processes and synchronizing with sensors, IoT optimizes energy consumption. It enables automated adjustments in lighting, HVAC, and other systems based on occupancy, leading to cost savings, reduced carbon footprint, and efficient asset upkeep

The system must be able to predict future temperatures as accurately as possible and make gradual, proactive adjustments to prevent energy overconsumption while maintaining consistent comfort levels. Implementing this on a large scale, such as an entire building with hundreds of different usage scenarios and types of connected sensors, can be a challenging task.

Goals first: Define your needs & desired outcomes. Software fit: Consider building size, controls, & strategy. Test with users: Facility managers need to find it user-friendly. Trustworthy supplier: Choose a long-term partner for ongoing support. Legacy software is a risk - buildings last decades, but software evolves rapidly.

Enhancing a building’s thermal capacity leads to improved insulation. As a result, HVAC systems operate more efficiently, consuming less energy. Investing in higher thermal capacity materials during construction yields a rapid return on investment.

Windows are a significant source of energy loss in HVAC systems. To mitigate this, innovative solutions such as double glazing and specialized coatings can be employed. These technologies help reduce heat transfer and improve insulation, thereby decreasing energy losses due to factors like solar radiation and high ambient temperatures. Coatings is preferred when the window is already installed
