Green Building- How it works !

-
In today's world we are facing so many issues regarding environment . Because of the Forest cutting pollution level continuously increasing everywhere. Today everyone forgetting how to maintain natural environment and how to save it. Day by day greenery is reducing and trees are cutting down , due to this air is getting polluted. As per WORLD METEOROLOGICAL ORGANIZATION temperature of the earth is increasing by 2 degree Celsius  every year.  Until now we destroyed the environment in a way we want. An important way to save environment is Green building.


Concept of Green Building :
 
   
     Green building are buildings or homes that are more energy efficient , produce less waste and  are healthier to be inside. Green building uses environmental friendly material which reduce transportation requirements and restores habitat .
  Hence it reduces environmental impact on the building or home and maintain a static environment inside a building .
  Green buildings are sustainable building. eg. Sustainable means to meet the need of present without compromising the ability of the future generation .
  Reducing building impact on human health and environment through ,
  • Better sitting 
  • Construction 
  • Operation
  • Maintenance and removal.
 
Green building doesn't mean that :
   
 Buildings that are totally green, produce zero emissions and totally environmental friendly.


Principles of Green Building :

    There are three pillars of Green Building

  • People's : It is the social responsibility of every people to make better living condition. 
  • Planet : we have to do a construction of a building in such a manner that it will have a less impact on the environment .
  • Profit (Economy pillar) : we have to think how we can reduce the cost for construction of building .
  
Material used for the construction :
 
Material used for the construction of Green Building includes sustainable and renewable material .
  Following are the materials commonly used :
  •  Engineered wood : It is made of wood fibre , wood dust and soft wood .
  • Natural Fibres : Natural Fibres are Cotton, Bamboo, wool . 
  • Bamboo : Bamboo just takes 5 to 7 years to grow completely. It is used to create framework supporting walls and flooring.
  • Cork : cork is a natural material made from the bark of the tree.
  • Steel : Steel is a highly durable green material which is recyclable . It is uses as a structure member of roofing material .
  • Natural clay : Natural clay is a natural resource which is available is the abundance. It can be used as plastering material.
  • Non VOC paints : This material does not emit and volatile organic compounds which are harmful .
  • Cellulose : Cellulose is made up of recycled paper waste and it is used as an insulating material .

Rating Systems of Green Buildings : 
    
  • Green building rating systems are performance credit systems that provides 'Green' certifications and ratings to the building.
  • They allocate points to specific 'Green' certifications.
  • For example, Indian Green Building Council (IGBC) has the following allocations:  
  1.     Sustainable Architecture and design                      5
  2.     Site selection and planning                                    14
  3.     Water conservation                                                18
  4.     Energy efficiency                                                   28
  5.     Building material and resources                            16
  6.     Indoor environmental quality                                12
  7.     Innovation and development                                 7                                      
                                                  Total points                       100

Introduction to Refrigeration and Air conditioning .

Introduction to Refrigeration-   The main components of the of the air cycle refrigeration system are: Compressor Condenser  Expansion device   Evaporator   In air refrigeration, the air is used as a refrigerant. In ancient times, air was often used for commercial purposes because of its free air supply. Air does not change its phase i.e, the gaseous state maintained throughout the cycle, so the heat transfer capacity per kilogram of air is very low as compared with the steam absorbing systems. Due to low efficiency and high power requirements; however, due to the weight and volume of the equipment, this system is still first choice for air cooling. cooling essentially refers to the continuous extraction of heat from substances (perishable foods, beverages, medicines etc.) at a low temperature level, then transferring this heat to the another system with a high potential temperature. Introduction to Air conditioning: An air conditioner    is a  s...

Montreal Protocol

Montreal Protocol is a global agreement made on substances that deplete the ozone layer to protect earth's ozone layer by removing the chemicals or hazardous gases which deplete it. It includes limiting both production and consumption of the substances which causes ozone layer depletion. This agreement was signed by 197 countries in  1987 and actually implemented in 1989. Under the original agreement (1987), developed countries required to phasing out of the CFCs in 1993 and achieve a 20% reduction relative to 1986 consumption level by 1994  and 50% reduction by 1998  relative to 1986. For developing countries time period given for the reduction of CFCs is by 2010.  Additionally developed countries required to reduce their production and consumption of halons relative to 1986. After the Montreal protocol signed new data showed the adverse effect on ozone layer. The parties come together to do modification in the protocol to enable,after this modification the co...
