Assignment 1.
A) BCA volume 2: performance requirement 2.6.1; The main thrust of BCA performance requirement for energy efficiency is to reduce greenhouse energy emission by efficiently using the energy.
B) Chapter 1 and 2 of this manual.
c) The building fabric, external glazing and shading, the building sealing, air movement
Areas of household energy uses
d)
i) Hot water: when needs to boil water, they should consider using energy sources that do not emit much of the greenhouse gases and they include: gas, electric heat systems and solar.
ii.Heating and cooling: Put water heaters is places they are commonly used for example in showers where hot water is needed oftenly.This is important because the pipe will be shorter ensuring that hot water is delivered fast hence less energy is used .Also to be installed and used are the AAA complaint showerheads .Set the water thermostat at about 60 degrees Celsius and a mixing valve must be installed to avoid scalding. And lastly insulated all hot water pipes.
iii. Cooking :Often use gas cook top because they produce less greenhouse gases as oppose to electric .Another reason is because they are simple to use .Another good option for less energy consumption are highly insulated and double glazed ovens.
iv. Electrical Appliances: Most of these electrical appliances such as refrigerators, clothes washers among others are already labeled in star form indicating their energy consumption rates and high the number of stars , the higher the efficiency of the appliance.(see HYPERLINK “http://www.energyrating.gov.au”www.energyrating.gov.au)
note that a larger model has a high rate of energy consumption though may have same star rating of small one .Places appliances that use hot water near hot water services as this reduces heat losses in pipes.
v.Lighting: A void low voltage down lights and encourage fluorescent ,compact fluorescent and LED lamps because they are more energy efficient. For outdoor areas use solar lighting and also zoning of lights in larger areas with separate switches is energy efficient.
Vi.Stand by energy: is the energy absorbed by some electrical appliances when the equipment is actually not being used. Example, make sure the TV is turned off by the switch not by remote control. Also encourage the use of Energy star logo approved equipment this reduces stand by energy consumption.

A) Ballarat; hot dry
Kathryn; temperate
Port Lincoln; temperate
Weipa; warm humid
Deloraine; Temperate
b)
c) Climate is the weather pattern of a given area studied after a period of time e.g. 30 years .This information collected is used in the computer modeling of building energy performance .Climatic graphs and charts are used for analysis for the data comparisons. Every kind of a building design needs a unique weather for the study.
The data obtain from the climatic studies will be useful in estimating the building’s energy consumption, design of heating, air-conditioning (HVAC) systems, ventilation and in the calculations of heating and cooling needs.
Assignment 5.
Assessment for Compliance (2009)
Step 1
Climate Zone is 5
Allowed Conductance = Area x Cu = 300x 2.2
= 660
Allowed Solar Heat Gain = Area x CSHGC = 300 x 0.17
= 510
Step 2
Worst Case values from the BCA. In this case values are 7.9
Actual Conductance =10x 4.2x 7.9 + 2×4.2x 7.9 + 5 x3.36x 7.9 +4×1.5×7.9
= 331.8+66.36+132.72+47.4
=578.28
The value obtained is below conductance and therefore it complies.
Assignment 6.
The proposed building exceeds the minimum requirements for BCA energy efficiency.
The angles shows best fit for the design of building because it regulates overheating and under heating problems caused by sunshine.
Assignment 7.
In this era of global warming or climate change, it’s everyone’s responsibility to make sure that use that they minimize emission of Carbon and encourage the use of more efficient energy solutions.
Skills connect is accredited energy auditing software; the course provides electricians with both theoretical and practical knowledge to pursue Energy Management Institute (EMI), the licensed energy audits for offices and residential.
To contact any of the accredited personnel kindly see the below contacts.
Sydney office HPM/LeGrand: Unit 2, 79-99 St Hillier’s Rd Auburn NSW 2144
(b)The House Energy Rating Software is used for the assessment and evaluation for the dwelling buildings and it must conform to the BCA standards for approval.
(C)Life cycle cost is a methodology applied in the calculation of the total cost of building ownership. It encompasses the total cost of acquiring, owning and even the cost of disposing the building.
Life cycle cost is mostly useful when building alternatives that fulfill the same performance standards, but differ with in terms of the initial costs and operating costs, have to be compared in order to select the one that gives maximum net savings.
Assignment 8.
Accessibility to good solar should be guaranteed particularly in cool climates since this ensures reduced energy requirements, improved comfort levels and it’s friendly to the environment.
