    3 Smart Buildings Demonstrating It’s Easy Being Green

    Posted by CleanAlert Blog Team on Aug 26, 2016 8:00:00 AM

    From a technological perspective, smart buildings make sense. From construction to building operations to the experience of its tenants, technology is impacting all phases of the building lifecycle. As a former architect, I have personally witnessed this transformation, as the Internet of Things has become a key design consideration in building construction projects.

    The most interesting part of adopting Internet of Things technology in the building space is that it is also having a positive impact on another building trend: green buildings. Here are three of the world’s most sustainable buildings and how they are using the Internet of Things to go green.

    The Edge - Amsterdam

    The Edge, a commercial office building in Amsterdam, the Netherlands, boasts a smart LED lighting system, which has over 30,000 sensors connected to the building management system through the Internet of Things. The lighting system measures Light levels, infrared radiation, motion, and temperature, allowing it to automatically adapt and adjust energy use. When a floor in the building is unoccupied at night, for example, all lights are automatically turned off and heating and cooling can be set to minimum. As a result, when there is zero occupancy in the building, there is next-to-zero energy use.

    During the day when the building is occupied, individual tenants can also view their sustainability data and control and personalize light and temperature settings through an app available on their smartphones. As a result, The Edge uses about 70 percent less electricity than the average commercial office building.

    These smart sensors impact more than just lighting though. Offices not in use can be skipped for cleaning, which lowers the use of chemical cleaning products. Facility managers can use real-time and historical occupancy data, as well as information about weather and traffic patterns, to calculate roughly how many people will eat in the cafeteria at lunchtime, helping avoid wasting food.

    Al Bahar Towers – Abu Dhabi

    In Abu Dhabi, United Arab Emirates, temperatures can reach up to 120 degrees Fahrenheit in the summer. These tremendous temperatures would normally be quite demanding on a building’s energy use, but not so for the Al Bahar Towers. The towers feature a façade that is covered with a remarkable mosaic of computerized, sun-responsive shades that help improve energy use.

    The lattice screen folds and unfolds in response to weather conditions, helping reduce solar gain by up to 50 percent. It usually operates in a pre-programmed pattern based on predicted sun conditions, but sensors can open the units in the event of overcast conditions or high winds. In addition to keeping the unforgiving sun out, the façade also contributes to improved daylight penetration and helps reduce dependence on artificial lighting. The system reduces carbon dioxide emissions by 1,750 tons annually in comparison to a standard building façade. 

    The Capital Tower - Singapore

    In commercial buildings, parking garages can be a significant source of pollutants that affect indoor air quality. The Capital Tower in Singapore, Southeast Asia, which was one of the first smart buildings in the city, is using Internet of Things technology to help solve this problem resourcefully.

    Normally, commercial buildings handle this type of indoor air pollution by running an exhaust fan. But this approach in itself can be highly inefficient because of the fluctuation in the amount of pollutants in the air typically occur based on occupancy. The Capital Tower’s exhaust fans are equipped with sensors that are connected to an intelligent building management system. They are only started in the parking garage when the carbon monoxide sensors register more than 1,000 parts/million, which results in significant energy savings while still providing improved indoor air quality.
