Global warming problem has become the focus of world attention. In recent years, the greenhouse effect has made a heavy global climate change and has seriously developed many illnesses and changes to our environment. These include ground level ozone which is a by- product of atmospheric reaction between nitrogen oxides, volatile organic compounds, methane, and carbon monoxide in the presence of sunlight. Another one would be the thinning of the protective ozone layer which leads to changes in our environment.
Chemicals typically come from combustion processes, industrial and vehicle emissions, chemical solvents, and natural sources. Effects include premature death from heart or lung disease, reduced lung function, increased susceptibility to respiratory infections, and increased hospital admissions.
In order to help reduce global warming, we have to use the available energy much more efficiently. We will have to change our behavior to reduce our personal energy consumption. We must change our current life style and seriously strive for a sustainable living.
Green buildings save energy costs by reducing the energy consumption. Traditional buildings consume more of the energy resources than any other building components. Therefore, green building materials are composed of renewable rather than non-renewable resources. They are eco-friendly materials which do not cause damage to human body. Green building materials consist of recycled materials; highly efficient insulation, agricultural buildings, bio cement, eco-cement, green concrete, green roofs, low-energy building, Zero-carbon building, eco-construction
It terms of appearance, there is no difference between green building and conventional ones but they do have better indoor environment which offers a lot of savings cost. Some benefits offered by green building are:
‘ Energy efficiency- green building are around 25%-30% more energy efficient.
‘ Reduced maintenance/replacement cost over the life of the building.
‘ Improved occupant health and productivity
‘ Lower cost associated with changing space configurations.
Green computing works at all level- development, manufacturing, usage and disposal to minimize technology’s impact on the global environment.
‘ Using energy-efficient hardware like notebook computers, displays, servers, printers and desktop computers.
‘ Using two-sided printers to reduce paper and energy usage.
‘ Centralized networked computer management software.
‘ Video conferencing as alternative to travel expense.
Green Computing is an environmentally responsible manner; it protects and saves energy along with operational expenses in today’s increasingly competitive world.
Solar panels- Solar panels work through what is called a photovoltaic process ‘ where radiation energy is absorbed and generates electricity
‘ Utilizing electricity from solar power will result in reduced consumption of fuels, thus reducing greenhouse gas emissions and pollution.
‘ Solar power systems will reduce or even eliminate office building’s electric bill.
COST AND SAVINGS:
Below for figure 1, is an average savings that can be achieved by a green building.
Figure 2, is an extensive research in conducting the cost of consumption levels of PCs.
Figure 3, explains the advantage of PV power in which cost has fallen while utility cost continue to rise.
To achieve maximum energy efficiency at the lowest cost, energy efficiency must be used at its best. The only way to achieve energy efficiency in a building is to diligently optimize the energy efficiency of every angle of the design, from start to finish.
Four steps to follow when considering energy efficiency:
1) Define green as achieving maximum energy efficiency at minimum cost.
2) Set an aggressive goal to achieve 25% reduction in every part of the building.
3) Perform energy simulations at the outset of the conceptual design phase to assess all energy-efficiency options with paybacks of 15 years or fewer.
4) Select an experienced design team that includes an independent energy consultant who represents the owner for achieving optimal energy efficiency.
Below is a time-line in which actions will be implemented in a timely manner based on expense and the gravity of work it needs for a more suitable approach for the work place. All three should all be completed within 1 yr.

Green technology is here to help encompass a range of subjects from new energy generation techniques to the study of advanced materials to be used in our daily life. Going green focuses on reducing the environmental impact of industrial processes and innovative technologies caused by the earth’s growing population. By taking on this environmental responsibility, not only will it reduce operation expenses, but it will also have a positive impact in our society. This serves as a great example of promoting growth for healthier and more comfortable living, and in return it creates a positive image to our consumers.
