Mengenal Green Software & Green IT

Pengertian :


GREEN IT :

( Green IT adalah sebuah study dan praktek dalam merancang , memproduksi, penggunaan dan pembuangan dari computer , server, dan system terkait lainnya seperti monitor , printer , Alat penyimpan dan network serta system komunikasi yang efisien dan efektif dengan dampak yang minimal atau tanpa dampak buruk terhadap lingkungan.)

In Harnessing Green IT: Principles and Practices a definition of green IT as provided by Murugesan is as follows:

Green IT is the study and practice of designing, manufacturing, using and disposing of computers, servers, and associated subsystems—such as monitors, printers, storage devices, and networking and communications systems—efficiently and effectively with minimal or no impact on the environment.

GREEN SOFTWARE :

( Green software adalah computer software yang dapat di kembangkan dan digunakan dengan efisien dan efektiv dengan dampak minimal atau tanpa dampak buruk terhadap lingkungan.)

In [1] the definition for green software is introduced as "Computer software that can be developed and used efficiently and effectively with minimal or no impact to the environment". This definition has been derived from the definition of green IT as provided by Murugesan in Harnessing Green IT: Principles and Practices.

Daftar 10 besar Green Software yang disusun oleh greentech media

1. eMeter
The company, which has raised $57 million in two rounds, has created a system that crunches the data from electrical meters for the benefit of utilities. It can monitor power consumption, maintenance issues, trends, outages, billing management, etc.  

It has an in-home thermostat application too, but it's not really the interesting part. It's how eMeter manipulates data for utilities that makes it valuable. Plus, it can pave the way for dynamic pricing schemes. Customers include Southern California Edison, TorontoHydro and CenterPoint Energy, among others.

2. Sustainable Spaces
Sustainable currently gets its revenue from energy efficiency retrofits, but the heart of the company is a complex application that allows contractors to determine the optimal repairs for a building.

"It is an expert system for decision support in the field," said president Matt Golden. "We have software meetings all the time." A number of the company's employees came from Google. The company's next task is to certify third-party contractors (i.e., not those working on Sustainable's crew) to get trained on the system. The retrofit market may become as crowded as building management, but for now Sustainable has a head start.

3. Autodesk
Product and building design. In terms of overall impact, the company will likely have a greater influence than anyone else on the list in terms of improving energy efficiency in buildings, reducing the amount of raw materials in manufactured goods, and replacing fossil fuels. But be honest, seeing Sustainable on this list is more of a surprise.

Honorable mention: Bentley Systems, which makes simulation and design tools for HVAC engineers.

4. Intermolecular
Think drug discovery software meets batteries and ultracapacitors. The company harnesses highly parallel computing techniques to devise materials and processes for semiconductor manufacturers and material scientists.

Biosciences companies have used these sorts of programs for years for protein folding simulations. Intermolecular exploits similar techniques to determine, for example, the optimal placement of atoms in a cathode and the potential results from various processing techniques. To date, Intermolecular has mostly worked with chip makers like AMD and Elpida, but it likely become a name solar and battery makers get to know.

5. Architectural Energy's SPOT
Not SPQR, SPOT. It stands for Sensor Placement and Orientation Tool and helps architects place sensors so that occupants can capitalize on daylight. Daylight saves energy-lighting consumes 22 percent of the electricity in the U.S. – but it can also improve worker productivity, moods and retail sales because of the improved quality of light. Ever wonder why everyone looks like a serial killer in a gas station bathroom? It's the poor fluorescents! Sunlight Direct, UC Davis and others also working on this issue.

6. GeoMation
Hitachi's GeoMation crunches satellite data to determine the optimum time to harvest wheat and rice. In tests on the island of Hokkaido, where farmers saw carbon dioxide output during harvesting reduced by 30 percent. In a world plagued by drought and hunger, this will come in handy. Expect to see a lot of lifestyle and heath applications come out of Japan too – weight loss tips, sleep monitors etc.

7. The Building Management 25
Building control systems used to mean the janitor. Now, it's a booming cottage industry with companies offering various combinations of hardware, software and services for curbing power inside commercial buildings, homes and university campuses.

At this point, it's hard to say who will win. Because of the varying customer needs, some sectors of this market will not rapidly consolidate: software for skyscraper management will likely be served by several vendors. The companies that provide software for thermostats may experience a quick bloodbath in the near future.  

Here are some of the more interesting ones: Cimetrics (software and simulation for campuses); Tririga (same); Adura Technologies (lighting controls-moving to total building management); Optimum Energy (air conditioner control) HydroPoint Technologies and Greenleaf (sprinkler systems); Advanced Telemetry (fast food outlets) and Tendril (home energy management consoles).

8. Hara
Why do I like Hara over the other carbon management companies? Because they don't yammer on about the importance of carbon accounting, which, in most parts of the world, remains voluntary.

Instead, the company tries to give a comprehensive view of the "organizational metabolism," according to CEO Amit Chatterjee said. If a company is mostly concerned about reducing energy costs, or water consumption, the remedial recommendations will be skewed toward the desired result or a blend of goals.

"It is not about greenhouse gases always," Chatterjee added.
