Explain the concept of high-performance green building. Include the following:

• Your reasoning to justify the appropriateness of sustainable construction practices (a minimum of three reasons)
• A minimum of three trends in high-performance building
• A trend you foresee in high-performance building in the near and distant future

• What are the differences between AASHTO 1993 and Al method? what are the similarities?

THIS IS AN ENGINEERING SUSTAINABILITY SUBJECT BUT I CHOOSE CIVIL ENGINEERING

You are required to come up with a significant engineering solution to address a sustainability challenge in Western Australia. Some key sustainability issues in Western Australia that are challenging for engineers to address include but are not limited to: Carbon emissions (reduce GHG emissions)

Question

1. Provide a summary of any one of the following improvement strategies to help solve the TBL problems associated with your sustainability challenge: Use Energy storage.

Climate change causes profound impacts on the environment due to the increased global temperature. Discuss briefly why and how climate change can potentially cause more flooding and excessive rainfall in some areas, and severe droughts in others.

A municipal wellfield is designed to consist of five water-supply wells, each rated at 16 litre/s. The wells are located 100 m apart along a north-south line and fully penetrate a 20m thick confined aquifer that has a transmissivity of 1000m2/day. . Estimate the maximum drawdown 500m west of the centre well assuming that all wells are 40cm in diameter and the radius of influence of each well is 800m. [15 Marks] 4b. If the calculated drawdown value is considered too low, propose 3 design options to ensure an increased drawdown.

Compute the settling velocity for the following particles: very coarse sand ( diameter = 1.5 mm ) , (diameter=1.5 mm), medium sand (0.4 mm), very fine sand (0.075 mm), and clay (0.001 mm). Estimate the time for each particle to fall 6 in. in water.

Assume: SG: coarse sand = 2.65, medium sand = 2.67, fine sand = 2.70, clay = 2.8 & water temperature = 60°F

Note:The other solution on chegg is wrong.

Using the regime-theory method, design a channel to carry wastewater from a manufacturing plant. Assume a design discharge of 950 ft3/s.950 ft3/s. The channel will have a sand bed and banks. Use a Manning’s roughness coefficient of 0.025.

Assume: Water Temp = 60°F, slope = 0.25%

▪ Describe the engineering aspects of two of MOSE Project and Thames Barrier
▪ Describe how fluid mechanics govern the design of these protection structures

A two-dimensional transient velocity field is given by

u = ax(b + ct)               v = ey(f+ ht)

where u is the x velocity component and v, the y component. Find:

1. The trajectory x(t), y(t) if x = x0, y = y0 at t = 0.
2. The streamline that passes through x0, y0 when t=0 and plot it.
3. The acceleration field.

a (-) = 5

b (1/s) = 5

c (m) = -1

e (-) = 5

f (1/s) = 5

h (m) = 4

x₀ = 1

y₀ = 2

A contractor provides you with a 5-gallon bucket sample to test the concrete. You observed that the entire chute was diverted three separate times in the middle of the concrete truck. Is this an adequate sample to cast two concrete cylinders? Why or why not?

Research (Literature Review):
[Search the net, see if there are paper towers that have already been made, what is unique in these towers. Select one idea from the net and explain its design. Provide a picture of the design.

please mention also the advantages and disadvantages of the design you choose it

If a bridge is above a river approximately 10 miles from the sea with a bridge deck of 170m

What type of concrete is should be used? will it be sulphate resistant concrete or high performance concrete or any other?

What will the Eurocode exposure class be ? will it be XS1 or XD1? or something else?

Will it be EN206/BS8500 type of concrete?
