A summer time temperature analysis of a relative zone of the
building, estimating the cooling load and a comparative study for a
different type and a different percentage size of glazing
What is convection cooling? How can you construct a building so
that convection cooling occurs?
What are thermal bridges? Give an example of some ways to
eliminate them when you are building?
What is the intention of the Innovation and Design Credits? What
are the responsibilities of the LEED Accredited Professional on a
project?
For a residential building with 5000W of heating demand,
estimate:
a) the number of required vertical
ground heat exchangers (borehole heat exchangers) to fulfill the
heating demand (round up the number).
b) the heat exchange rate for each ground heat
exchanger if boreholes are 30m deep (W/m).
Design parameters and assumptions:
The circulating fluid in the pipes is water with a temperature
difference of 5°C between inlet and outlet pipes (Tout -
Tin= 5°C) and Reynolds number of 5,000. Pipe...
An air-conditioned zone is at 72°F and 40% relative humidity.
The total heating load of the space is 300,000 Btu/hr, out of which
60,000 Btu/hr is latent heating load. To maintain an appropriate
indoor air quality 1000 CFM of outdoor air at 30°F and 80% relative
humidity is required. Determine:
a) flow rate of supplied air at 25 °F above the zone
temperature
b) total heating unit load
c) amount of water required for the humidifier

In order to estimate
the difference between the MEAN yearly incomes of marketing
managers in the East and West of the United States, the following
information was gathered.
East
West
n = 40
N = 42
X = $73,000
X= $71,500
S = 3500
S= 4000
Develop an interval estimate
for the difference between the MEAN yearly incomes of the marketing
managers in the East and West. Use α = 0.05. Note that the
population standard deviation is unknown, but...

The following estimated regression equation was developed
relating yearly income (y in $1000s) of 30 individuals with their
age (x1) and their gender (x2) (0 if male and 1 if female). Ŷ = 30
+ .7x1 + 3x2 Also provided are SST = 1200 and SSE = 384. The test
statistic for testing the significance of the model is
