the most optimum level and that itself
the most optimum level and that itself can lead to an additional 10 to 15
can lead to an additional 10 to 15
can lead to an additional 10 to 15 percent savings maybe even more
percent savings maybe even more
percent savings maybe even more audits of a lot of projects and I
audits of a lot of projects and I
audits of a lot of projects and I realized that you know just by operating
realized that you know just by operating
realized that you know just by operating the system at its design levels you can
the system at its design levels you can
the system at its design levels you can actually improve by a factor of 20 25
actually improve by a factor of 20 25
actually improve by a factor of 20 25 percent and in terms of comfort you know
percent and in terms of comfort you know
percent and in terms of comfort you know the the next big thing that is happening
the the next big thing that is happening
the the next big thing that is happening now is passing on the controls in the
now is passing on the controls in the
now is passing on the controls in the hands of the users right today we put a
hands of the users right today we put a
hands of the users right today we put a sensor to tell us you know how cold it
sensor to tell us you know how cold it
sensor to tell us you know how cold it is or how warm it is and we put a cutoff
is or how warm it is and we put a cutoff
is or how warm it is and we put a cutoff saying that if it touches 24 degrees you
saying that if it touches 24 degrees you
saying that if it touches 24 degrees you know cut it off what does the sensor
know cut it off what does the sensor
know cut it off what does the sensor doesn’t work right the best sensor is a
doesn’t work right the best sensor is a
doesn’t work right the best sensor is a human skin a human body we know whether
human skin a human body we know whether
human skin a human body we know whether it may feel hot for less or more and so
it may feel hot for less or more and so
it may feel hot for less or more and so if we can actually on our mobile phone
if we can actually on our mobile phone
if we can actually on our mobile phone can adjust it instead of using another
can adjust it instead of using another
can adjust it instead of using another sensor we can really operate that system
sensor we can really operate that system
sensor we can really operate that system at its very optimal level and I see this
at its very optimal level and I see this
at its very optimal level and I see this trend happening more and more where user
trend happening more and more where user
trend happening more and more where user control is going to take over from
control is going to take over from
control is going to take over from sensors so how does all these learnings
sensors so how does all these learnings
sensors so how does all these learnings right help I mean none of this is can it
right help I mean none of this is can it
right help I mean none of this is can it can actually work and it cannot be you
can actually work and it cannot be you
can actually work and it cannot be you know it won’t work unless it is
know it won’t work unless it is
know it won’t work unless it is sustained by profits right and so was
sustained by profits right and so was
sustained by profits right and so was this whole journey at Infosys profitable
this whole journey at Infosys profitable
this whole journey at Infosys profitable well what happened is that the lesser
well what happened is that the lesser
well what happened is that the lesser heat gained right for Less the heat gain
heat gained right for Less the heat gain
heat gained right for Less the heat gain they used super insulated buildings very
they used super insulated buildings very
they used super insulated buildings very high-performing windows all of that so
high-performing windows all of that so
high-performing windows all of that so that increased costs but what also
that increased costs but what also
that increased costs but what also happened is that they were able to
happened is that they were able to
happened is that they were able to reduce the cost of the equipment’s the
reduce the cost of the equipment’s the
reduce the cost of the equipment’s the mechanical equipments came down
mechanical equipments came down
mechanical equipments came down dramatically which is the chillers pumps
dramatically which is the chillers pumps
dramatically which is the chillers pumps cooling towers they choose the size of
cooling towers they choose the size of
cooling towers they choose the size of all of those equipments came down
all of those equipments came down
all of those equipments came down dramatically the connected load
dramatically the connected load
dramatically the connected load electrical load came down dramatically
electrical load came down dramatically
electrical load came down dramatically so the size of the DG sets the
so the size of the DG sets the
so the size of the DG sets the transformers the cables came down
transformers the cables came down
transformers the cables came down dramatically because these two came down
dramatically because these two came down
dramatically because these two came down the size of the utility building came
the size of the utility building came
the size of the utility building came down dramatically right so all of this
down dramatically right so all of this
down dramatically right so all of this reduction these costs the MEP costs was
reduction these costs the MEP costs was
reduction these costs the MEP costs was far more than the cost they invested in
far more than the cost they invested in
far more than the cost they invested in making the buildings more efficient so
making the buildings more efficient so
making the buildings more efficient so in the end Infosys was able to save five
in the end Infosys was able to save five
in the end Infosys was able to save five percent in capital costs and 50% in
percent in capital costs and 50% in
percent in capital costs and 50% in operating costs
operating costs
operating costs so can we not take this learning from
so can we not take this learning from
so can we not take this learning from this one company over the last 10 years
this one company over the last 10 years
this one company over the last 10 years extremely well-documented and take these
extremely well-documented and take these
extremely well-documented and take these learnings to all over the world
learnings to all over the world
learnings to all over the world we tried that very hard you know we
we tried that very hard you know we
we tried that very hard you know we published all this information in the in
published all this information in the in
published all this information in the in the on the internet but there are very

all the success stories of Infosys of
all the success stories of Infosys of you know having grown their employees to
you know having grown their employees to
you know having grown their employees to end by a hundred and twenty percent at
end by a hundred and twenty percent at
end by a hundred and twenty percent at the same time the energy grew by only
the same time the energy grew by only
the same time the energy grew by only thirteen percent they save hundred
thirteen percent they save hundred
thirteen percent they save hundred million dollars in operating costs in
million dollars in operating costs in
million dollars in operating costs in eight years right
eight years right
eight years right none of this really made a big dent in
none of this really made a big dent in
none of this really made a big dent in developers in our country and so my one
developers in our country and so my one
developers in our country and so my one formula of really making change driving
formula of really making change driving
formula of really making change driving change at scale is to incentivize the
change at scale is to incentivize the
change at scale is to incentivize the developers dramatically if you give them
developers dramatically if you give them
developers dramatically if you give them a 25% additional profit what will happen
a 25% additional profit what will happen
a 25% additional profit what will happen overnight they’ll do a PhD in green
overnight they’ll do a PhD in green
overnight they’ll do a PhD in green buildings right and that not just give
buildings right and that not just give
buildings right and that not just give them profits but the tenants who are
them profits but the tenants who are
them profits but the tenants who are occupying these buildings will pay 50
occupying these buildings will pay 50
occupying these buildings will pay 50 percent less in their electricity bills
percent less in their electricity bills
percent less in their electricity bills in electricity bills constitute about 25
in electricity bills constitute about 25
in electricity bills constitute about 25 percent of the rent right the everybody
percent of the rent right the everybody
percent of the rent right the everybody around them will go because you will
around them will go because you will
around them will go because you will consume less resources so it’s a benefit
consume less resources so it’s a benefit
consume less resources so it’s a benefit it’s a win-win-win situation for the
it’s a win-win-win situation for the
it’s a win-win-win situation for the developers tenants community and the
developers tenants community and the
developers tenants community and the world in general and this I think is
world in general and this I think is
world in general and this I think is really important that we all
really important that we all
really important that we all collectively start demanding action and
collectively start demanding action and
collectively start demanding action and driving change
driving change
driving change it’s our individual choices that can
it’s our individual choices that can
