Answer 13

CELLULOSE! PLANTS = RENEWABLE ENERGY!

Question 14

CO2E

Answer 14

• TYPE TO MEASURE C02
• CARBON DIOXIDE ESTIMATE/EQUIVALENT?
• called estimate because it hasn’t been produced yet
• THEY ABSORB C02 = ACHIEVED R- VALUES

• ECOSYSTEM QLTY
• CLIMATE CHANGE C.C
• RESOURCE DEPLETION

Question 17

HOW DOES A BUILDING GENERATE
ENVIRONMENTAL IMPACTS? (9) C.U.T.E.M.M.I.R.D

Answer 17

RELELEASING EMBODIED CARBON THROUGH:

EXTRACTION
TRANSPORT
CONSTRUCTION
INSTALLATION
MANUFACTURE
USE
MAINTENANCE
RENOVATION
DEMOLITION

Question 18

2 TYPES OF EMBODIED CARBON

Answer 18

1- UPFRONT CARBON

2- OPERATIONAL CARBON

Question 19

What do you think is greater,
upfront or operational carbon?

Answer 19

• UPFRONT CARBON

Question 20

ENVIRONMENTAL PAYBACK PERIOD (LCA STUDY)

Answer 20

Time it takes for the environmental impact
to be the same as the alternative

ALWAYS MAKE COMPARISON!

Question 21

WHAT DO YOU CALL A CARBON THAT IS ALREADY EMMITED

Answer 21

UPFRONT CARBON

ALREADY IN THE PAST!

IT REALLY DEPENDS SUCH AS THE CITY, TRANSPO. CLIMATE FACTORS

Question 22

ENVIRONMENTAL PAYBACK PERIOD ? HOW MANY YEARS COMPARED TO A NEW VS EXISTING BLDG

Answer 22

10 to 80 YEARS

• to overcome, through efficient operations,
• the negative climate change impacts related to the construction process.

Question 23

WHAT IS THE MAGIC NUMBER (YEARS) FOR BLDGS

Answer 23

26 YRS

2050-2024 = COP TARGET!!!!!

Question 24

BUCHANAN BUILDING, UBC ISSUE?

Answer 24

DEMOLISH AND BUILD NEW VERSUS
RENOVATE EXISTING BUILDING

THEY DID A STUDY, AND LCC MAYBE THEY CAN REUSE IT?

Question 25

EPPAYBACK BUCHANAN BUILDING, UBC ISSUE?

Answer 25

38 YRS

Question 26

WHEN should the Net carbon emissions savings for the new building begin?

Answer 26

begin only after 38 years. - TOTAL CARBON EMISSIONS OVER 80 YEARS: ONLY 5% LOWER WITH NEW BUILDING = minimal and not worth it therefore keep the old, renovate it bc E.P.P DID NOT MAKE SENSE IF EPP WAS 5 YRS, = ENERGY EFF. YES IT MAKES SENSE BUT 38 YRS WAS NOT

Question 27

WHY

Answer 27

B/C UPRONT CARBON EMITTED IS SO HIGH - TREMENDOUS CARBON EMISSIONS ARE BEING EMITTED= CAN'T BE IGNORED! EVEN IF IT'S LEED!

Question 28

UPFRONT CARBON

Answer 28

- IS EMMITTED BEFORE A BLDG IS - OPERATIONAL AND - CAN SIGNIFICANTLY OUTWEIGH

Question 29

4 EXAMPLES OF STANDARD RATING SYSTEMS IN CANADA

Answer 29

1- LEED 2- PASSIVE HOUSE 3- BATIMENT PASSIF QUEBEC 4- NATIONAL ENERGY CODES OF CANADA 2020

Question 30

Functional statements ACCDNG TO energy code (4 LIMITS) W.A.T.E

Answer 30

* Limit air leakage * Limit thermal transfer * Limit energy consumption * Limit water consumption

Question 31

WEAKNESS OF CODES

Answer 31

THEY ONLY CARE THE AMOUNT OF RVALUE OF R30 ON YOUR WALLS, THEY DON’T CARE WHAT TYPE OF INSULATION YOU USED - DO MORE DAMAGE THAN GOOD, DON’T LOOK AT THE OPERATIONAL, BUT THE UPFRONT

Question 32

CONS WITH LEED

Answer 32

- TOO WIDE RANGING - NOT FOCUSING ON CARBON/OPERATIONAL - POINTS ARE EASILY GET WITHIN THE IMPACT CATEGORIES - that demonstrates a minimum of 10% reduction - they just target the minimum and it’s pathetic that it’s very easy to attain Leed Certificate

Question 33

LCA & LEED - CASE STUDY SOPREMA MANUFACTURIng FACILITY WOODSTOCK, ONTARIO, 2019 ALL-NEW CONSTRUCTION, wch category are they aiming for the have points

Answer 33

Materials and Resources” (MR) category.

Question 34

5 elements of a structure and say it from highest to lowest % total mass of materials S.S.I.O.R

Answer 34

Structure Footings, foundations, below-grade insulation & membranes, ground floor slab = 87% Superstructure Steel beams, columns, etc = 6% Interiors = 4% Outer envelope Sandwich panels, aluminum cladding, glazing, metal studs, air & vapour barriers =2% Roofing Membrane, insulation, green roof =1%

Question 35

HOW TO ACHIEVE LEED POINTS IN THIS CATEGORY?

Answer 35

- Minimum 10% reduction - in at least three of the six impact categories - one of which must be global warming potential.

Question 36

To a Reference Building not green Per m^2

Question 37

2 most carbon emitting materials

Answer 37

Concrete and insulation
