Hello. My name is Oliver Can On on today I'm

presenting a paper titled Our Ends.

Herbs nearly End seven off on Dhe.

I am a lecturer in sustainable design technologies on building

performance at University College, Dublin School of Architecture, Planning and

Environmental Policy.

And I wrote this paper with my colleagues there, Richard

or Hagerty.

Dona Lenin.

I'm Shane Kulti on this work is part of the

ends of one or one project which is a project

that is Anna Light monitoring the performance on analyzing the

performance of 100 more near zero energy buildings around Ireland

and comparing the performance in use against the performance, the

design performance of the how these buildings were supposed to

perform. The paper outlines a bold experiment based on construction

projections and from 2060 2060 phenomena.

Off building usage are identified using some real data from

Kayseri buildings off.

This ends at 101 project.

Today we have over 230 billion m squared off builds

floor area on the operation of those buildings results in

more than tree trillion kilograms of Sio two equivalent in

a single year.

So these are numbers for 2018 but it's the same

for more years.

And if we take into account the indirect emissions from

power generation on, this becomes almost 10 trillion kg off

see or two equivalent to run the buildings we have

today. And if we continue on that trajectory, we will

add over 570 trillion kg of CO two equivalent by

2060 through the operation of the buildings we have in

existence. No, these buildings aren't ends up, nor were they

designed to near zero energy building standards.

But when we compare the performance off this off the

of our building stock with say, for example, the estimated

carbon budgets for on dhe 50% chance of avoiding of

1.5 degree Celsius rise in global temperature then and it

becomes quite worrying because 572 trillion kg of sea or

two equivalent is more than the 480 or approximately 500

trillion trillion kg of sea or two equivalent that the

majority of these models proposed is the treasure old for

for a 50% chance of avoiding on 1.5 degrees Celsius

on rise in temperature on on top of that were

set to build to over 230 billion m squared off

Florida. So that's the same floor area again, would be

built by 2060 and that the reason behind that is

because our population is increasing from our dramatically.

But also we're also expanding the amount of floor area

that each of us require on year on year on.

The numbers there are quite shocking.

In this paper we look a real case study taken

from the ends of born or one on project.

We analyze its real performance Onda.

We then extrapolate those numbers to represent the new buildings

that have to be built worldwide.

Um, on do and we can't quantify compared that to

the carbon budgets to get an understanding off how far

were over shooting the remaining budgets if we want to

avoid climate change, I mean, one of the things that

the doctor shows is that buildings that are performed that

it all designed all these buildings that you see here

on this image or all designed to the same standard.

Um, however, they all operate with very different energy performances

on someone twice the energy performance of buildings designed to

the exact same standard.

So one of the things we talked about in the

paper is the role of the argument on how even

if we design all our new buildings to the ends

of standard, that we can't account for for many multiples

off performance beyond the design performance and that that is

going to increase the risk on dhe are the impact

of off our new built environment on dhe.

Further, I would ask you to even invite you to

to read the paper.

Andi, I hope that you will enjoy it.

My name is Oliver Kanaan on.

Thank you for your time.
