New Horizons in Smart Building Technology

]]Applications in the new building in Tokyo – Akasaka]]

In our day, new technologies are developed to increase energy efficiency without waiver of our comfort. Kajima is one of the leading companies in Japan on new generation “green buildings” focused on energy efficiency. As of March 2007, the energy saving technologies developed by Kajima are implemented in 123 buildings. The carbon dioxide release, which leads to global warming thanks to the use of such technologies in these buildings, is reduced to 32,343 tons per year. In 35 years of operating time, this figure is divided into 1.128,505 tons of CO2.

In this article, we will talk about these technologies that Kajima has applied in the central office building, which is moved to new in the Akasaka district of Tokyo. [

How do we prepare comfortable working environments to people? The idea “eko-modul” was developed by Kajima appeared from this simple question. “Eko-Module” is a smart system that detects people’s availability and saves energy by providing comfort to their location. On this system, open office areas are divided into virtual “modulated” according to people’s living spaces. So there is no physical partition between modules. In this system, a smart technology is used to measure light, temperature and human availability (occupancy) and provide optimal bright and thermal conditions in human modules. In this way, the energy consumption is lost in modules that are not human.

This system makes even more than adjust the light and temperature through the alerts. Eco-modules also adjusts the status of window shutters, measurement the position and angle of the sun. In this way, the daylight is used in optimally in lighting, while at people work in the building, some shutters are automatic enough lead to “the sense of isolation”. In addition, the solar energy is made in the heating season, while in the cooling season, an important energy is saved by leaving outside. The days where lighting switches and hand-controlled shutters are accessible not far away. [

Local and General Climateing System]]]

Instead of using huge central air conditioning devices to heat or cool the entire building, with a “genel” (ambient) decentralized system that meets the basic heating/cooling loads, along with a “local” (task) decentralized system that meets variable local loads caused by people. The general system meets the heat loads, which is quite stable, from the condition of fresh air entering the building, from the heat transfer of the building and the general lighting of the building. The local system meets the constant-changing heat loads from people and their activities in the interior. Both systems use a shared network of hears to ensure comfort requirements.

Kajima has also improved the concept of “iversal ventilation” to provide optimal comfort with minimal energy. Until recently, the airflow Engine from ventilation systems in Japan was adopted as low retention principle, which would not be felt by people. However, the research in time has shown that the airflow has a positive effect on people who feel some of the airflow Engine note over. In this “iversal ventilation” concept where Kajima was developed, the possibility to adjust air speed according to the comfort of people. In summer, people find a light breeze more comfortable. In this way, the sense of comfort can be seen in less cold atmosphere, an important energy saving can be made in the cooling.

Hibrid (Melez) Thermal Storage System

Energy saving does not mean only to jealate energy consumption. A measure that can be taken in this regard is also used in hours where energy is cheap. This means the dense consumption of electricity in places where three parts are billed, made at cheap night hours. Thus, both the electricity bill has been reduced, and the “max demand” status is blocked. Kajima is among the first companies that use thermal storage systems in buildings.

Thanks to this system, the cooling devices are stored in “cooling energy” where electricity is cheap and manufactured at night hours. Two methods for storage are monitored: in the first, ice is produced and stored. Cold water is produced in the second method and the concrete of the ventilation system is distributed.

It is necessary to “front cooling” by discipline through air or ice storages or the structure of the building through the cooling concrete structure. Kajima, which stores cooling energy in both ice storage and in the concrete of the building, has delicious flexibility and practicality in cooling. The word “hibrid” used in the automotive industry is not far from the time to be used in circular and descent systems.

Bina Energy Management System[[

When new technologies that increase energy efficiency are evolving, Kajima has developed a technology that detects what energy is spent on appetite space in existing systems, and uses it for a long time. This system collects and evaluates climate control and energy consumption information from a large number of hears in the buildin g. For example, push-ups the maximum energy usage hours, which conditions occur, the energycost systems in the building are working with full capacity. As a result of the assessment of this information, Kajima’s food advice the operator by detecting the necessary measures to make the operation more efficient, changing or dispose of devices. Thanks to this system, the devices provide replacements after filling the optimal economic lives, and the energy, and the device usage, and the pressure on this environment is distributed. In this way, the owners of buildings have minimized their business appetite. [
