But think of the United States
negatively impact

our environment more
than any other industry.

Statistics show that building is use
thirty nine percent of all energy use

thirty eight percent of
the C O two emissions and

over forty percent of raw material use.

Now these impacts can be lessened.

And that involves selecting materials
that reduce the negative or

that reduce the impact on the environment.

And the depletion on or nubile resources.

Sustainability also has to do with the
whole construction process as a whole and

this rich this research
focuses on optimizing

all the decisions by at every stage of
the project and by every team member.

So this includes better communication and
coordination between

the architects engineers construction
facility management team.

According to the National been standard
building information modeling is a digital

representation of the physical and
functional characteristics of a facility.

It offers a single point of reference for
all the parties to get accurate and

consistent data about a building

there are many different
programs then programs out there.

Google Sketchup is
the simplest program but

as you can see still produces
very detailed results.

Rev IT architecture that is the program.

I've used throughout my research
because I'm most familiar with

it through my classes as
well as the ability for

for this program to be manipulated by
the user the amount of information that

can be stored of objects and
the detail that it

offers them as is throughout every
stage of the project from the initial

you know idea through mechanical and
structure design

all the way out in the field for the
contractor sees as a working forty model.

Now.

Leadership in Energy environmental
design better known as lead this.

This was developed by the United States
Green Building Council in the mid

ninety's.

It's become the accepted
third party rating system for

sustainable buildings lead for
new construction outlines five

key areas that make a building
healthier for the occupants and

more environmentally friendly and
you can see those on the left side.

So over this research I decided
to focus on the points within

these categories that involved
a material selection.

So these include roofing materials and any
materials reuse from previous buildings.

Pre or post consumer recycled content
regional and rapidly renewable materials.

So this this.

My this right here is the proposed method
of integrating this lead system with

in a rather model currently
After all my research I found

no tool that directly measures
the lead points in the bin.

But even though all the architects and

engineers and construction management
companies are using both these systems

they haven't actually found
out a way to put it together.

So I don't see why you and
you know naturally.

Document and make decisions of lead
in a rabbit or other bin system.

If you see that lead toolbar
on the left you would.

Those buttons would take you to all the
information that you need to know about

testing the applicable credits.

So when a model or
starts out using a been program.

They're starting a project and they enter
all of the basic project information.

So the information I found
is going to be necessary for

accounting week credits are the location
of the project occupancy

numbers whether that be residents of
it's a residential project peaked.

In users or full time equivalent given.

And also the materials cost
estimate materials cost estimate

is used in almost all of
the material point equations.

That a model a bit model
uses is made up of unique

objects that are part of families all
of these objects have attached to them.

Element properties and
the name information model.

So it's very easy to add
parameters into an object and

the ones that I've added for
lead are the filler reflectance index.

This is something for

everything in paving materials
the manufacture and vendor location name.

The recycled content percentage of

the cost of the of the material in
the lead credits which applies.

So I'm not going to go
through a few examples.

Just to show you how this
program would actually work

the first one is relatively simple.

It's for materials and resources credits
six rapidly renewable materials.

The tool would search through all
of the objects in the model and

find the lead credit line that's
that's called rapidly renewable.

And another point to mention here is read
it does automatic quantity take offs.

So as long as even at a cost
into the object parameters.

It can give you a cost of all the material
happily renewable Tira materials in your

building so divide this by that total
materials cost and for this credit

if that number is at least two and a half
percent than it achieves that lead credit.

Another point important part to
mention about lead application

is there is a very specific documentation
process that goes along with this.

If you remember that lead toolbar that
we had on the left side of the screen

when you click the materials and

resources credit six it will
take you to this window.

This box to give you all gives the all
the information they need to know

the total cost of materials you
currently have in your building.

And the percentage of the total materials
costs and whether or not you have met that

credit in any example are exemplary
points that you can achieve.

If you have got some metal button.

It takes you to this graph and this graph
gives you exactly what is needed for

the application process in this case that
is the material description manufacture

and materials costs and now this
craft can easily be uploaded online.

So the online application form and

you've done some points also asked for
drawings to be submitted.

So if you hit the show button it'll
take you to the revenue floor plans

of ation sections three D. views and

highlight all the instances where
the rapidly renewable materials

are found in this case that's the bamboo
flooring and we poured cotton the tree.

The second example regional materials.

It's adding another parameter to
the element which is the manufacture and

vendor location for
material to be regional It must be.

Manufactured and purchased within five
hundred miles of the project site so

search all those parameters look at
the City of your projects site compare it

with the city of the of
those two companies and

if it qualifies as under five hundred
miles it will sum up the cost.

Divide that by the total
materials costs and once again

tell you whether that percentage gives
you the lead credit or you're aiming for.

This thirty sample is a little
different from the previous two because

the tools doing some geometrical
calculations as well.

The first requires you to look into all
the families of reefing material and

calculate the slope for
that was here for that plane.

If that roof plane also meets the solar
reflectance index which is one of those

element properties then.

And it will be a qualifying material.

That must calculate the root
surface area of the call fine.

Roof materials and
divide that by the total roofing area.

Now what I've shown you here is only
a small portion of the available

the possibilities available by compain
combining been mainly design and

keep in mind it's just you know.

It's just a concept at this point there
are a tool actually working on Reddit

hasn't been designed yet but my tools just
there to show you how it would work and

the benefits for
the sustainable building movement.

I think the soil could be
realized with coordination.

But with rabbit advancing
their object library

allowing more calculations
to be made within the system

in we also to make sure every party
every part of the team project

team is on board with using the rabbit
model as a single source of information.

But the most important outcome I want
you to leave with is the the dementor

the optimization dimension of this tool
it been model allows all of the project

team members to adjust the building
throughout the whole project stage so

they can the architects engineers
construction of selling managers can look

at the current owner needs the cost
limitations and the desired leave and

lead certification level and they can
decide make the best decisions and

will cut down on costs avoid litigation
and help with the scheduling.

So I think for this tool to advance.

It would need to be tested in the field
on real project run some simulations and

get feedback from the project team
members to see the benefits of the tool.

I've also like to see more lead
credits analyzed with the tool.

I just focus my work on material but there
are tons more credits that we can analyze.

And the favor will be published at
the two thousand and nine A.S.C.

international workshop in June.

If you have any questions for me.

Yes.

I mean there are.

Knots on my head but if you like the U.S.

Green Building Council does all
the studies for this and the lead.

I mean it's just taken off every
government building now has to

be Earth is going to have to be lead
now so it definitely saves a lot and

so this is just the already
doing all those environmentally

smart things this is just a way to
optimize the team work fast track it.

And we.

More it's OK.

That when I showed you
the all the lead points.

It's for a sub for
materials and resources.

So these are the five main categories and

under each of these categories there
are different different credits so

that was credits six of them
rapidly renewable materials.

They get you points and
as you get more points your building.

Is either it starts with a certified level
to certified lead then it goes silver or

gold platinum and you know as
the percentages of points go up.

So you're trying to get
to that to your desire.

Desire level.

United States Green Building Council.

Lead That is the Leadership in Energy and
Environmental Design.

This is this program that they
developed to is just a way to measure

how these buildings
are became becoming sis.

Anabelle saving energy.

Not using non-renewal
sources water efficiency.

Yeah that would be sustainable sites and
the heat island effect.

Rabbit that is just one
of the bin programs.

It's a very popular one made by Autodesk
S.S. the name of the program which you.

Lead to get out of the.

US So as the total number of points.

It's so it's a project is
trying to reach this point.

So you can you know way.

How much you want to cost and whether it's
worth it to you to use these materials and

get those points which we
thought it was always.

Yeah.

It would.

It can be.

I mean that wasn't my focus but it is
definitely a possibility too because there

are a quantity takeoff which produces the
final estimate of the building available

in the the Rev It program.

So I mean that would be a whole
different study is actually

looking comparing those costs.

And yes you know one.

You know.

Well you know I mean right now this
is very conceptual in Photoshop.

So we would have to explore this more and

you know I know nothing about
computer science or programming so

it would definitely have to be
working with Autodesk too and

you know there's ways of doing
some parts of the lead stay.

Days on end rather they
do energy analysis and

solar studies which is part of it but
it just doesn't actually show you.

Whether you're teaching these points
that still you know outside calculations

male calculations.

So I can see I mean I see the future of
them wanting to combine them because lead.

It's also the future.

Every buildings.

You know going to have
to meet some standard.

So that I have to combine them eventually.

Yes yes.

I hope

I'm graduating actually so
I don't know where I'm working at but

hopefully with my work I can continue
studying this or handed down to other

college of architecture students to
keep working on right well thank you.
