hi Architects,
since hvac is becoming a major foctor towards global warming. it regulate comfort inside the room but hot fumes are added to our atmosphere .through terrace gardening or gardiening between the floors ,the whole area will fully ventilate or by evaporated air cooling the temp. will decrease in HOT DRY CLIMATE. i am intrested in designing these kind of building . CAN ANY ONE HAVE ANY KIND OF INFORMATION RELATED TO THIS TOPIC. or site in india to easily accomplish my thesis.
thankyou |

HVAC is becoming a major factor towards global warming?
this is an interesting claim...lol, got some data/info to back that up?
Natural ventilation is def. a good idea, but keep in mind we need to build to code and standards. So on a commercial building you are limited, single family home may be different with more flexibilities.
Note there are many types of heating/cooling systems to choose from.
Another area to look at is the building envelope (wall and window) keep this ratio at max. 40% windows and if you realy want to save energy go with "triple" glass windows.
The ideas of gardens etc. is also a great idea, and is not realy being used enough in high rise buildings (green roofs, internal gardens etc.).
There is also a solar a/c unit you may be interested in:

I have this listed on my construction industry "other" links web page under Green Energy, may help you with other links in this area.
Happy Savings

It is a commonly quoted statistic that 50% of energy use in the developed world is expended on the construction and servicing of buildings.
The Wikipedia article on "Energy Conservation" is interesting reading. In the US 11.5% of energy in the domestic sector is spent on cooling systems (against over 30% on heating and 10% on lighting). The commericla sector expends 25% of its energy on lighting and 'only' 30% on heating/cooling combined.
It would be interesting to see similar stats for India. I expect the vast majority of the population expend far less energy on servicing their buildings than in the US and Europe, partly because of the very different climate. |

Natural ventilation and residential temperature control through ventilated (sloted) floors and walls are very common in tropical locations and in old praerie housing used in the old midwest USA.
Modern use of this Roman and Greek ancient system of airconditioning is reused in this FLW project

The Taliesin Mod.FabTM is an example of simple, elegant, and sustainable living in the desert. The one-bedroom, 600-square-foot prototype residence relies on panelized construction to allow for speed and economy on site or in a factory. It can be connected to utilities or be "unplugged," relying on low-consumption fixtures, rainwater harvesting, greywater re-use, natural ventilation, solar orientation, and photovoltaics to reduce energy and water use. The structure is dimensioned and engineered to be transportable via roadway.
The Taliesin Mod.FabTM was designed and built by graduate and undergraduate students at the Frank Lloyd Wright School of Architecture with the faculty guidance of Michael P. Johnson and Jennifer Siegal, project manager Christian Butler, recent M.Arch graduate, and assistant project manager Nick Mancusi, current BAS student.
The structure can be visited on the student-led Taliesin West Desert Shelter Tour, Saturdays at 1:30 until April 25, 2009. |

As I asked before please provide a LINK to show that HVAC is contributing to global warming.
