Increasing the sustainability through retrofitting:
Retrofitting is a good option to make a building more sustainable by making it more energy and
water efficient and reducing its waste thus making its carbon emissions also low and making it
eco-friendlier. Making the building sustainable is good option when it is currently in its
construction phase and all the working is done previously, before the project starts. On the other
hand, the costs would be much higher if the building is already constructed and then at a later
stage it is decided to make the building sustainable as that retrofitting at the time would cost a
lot, comparatively.
Building and its current utilities:
Presently the building is using a large amount of electricity and water directly from the grid and
Sydney water. The electricity amounts to approximately 1,163,200 kwh as per 2015/16 which
costs a lot of amount. The water usage of the building is also high which is 7,800kl as per 2015.
The gas usage of the building is approximately 195 GJ per annum.
Retrofit Options for 7 Macquaire Place:
As AMP is considering the retrofit for its property of 7 Macquaire Placeand after the retro fitment
they plan to keep the building until the end of its life. Retrofit options that are provided in this
report include short-term, sort to medium-term and long-term options. These retrofit options
would help to make the building more sustainable which would in turn increase its life as well as
become more energy efficient and decrease the carbon emissions as well. Below are the short-
term, short to medium-term and long-term options available for 7 Macquaire Place.

Retrofit options for short-term (0-2 years)
1. LED lighting system in parking:
Although 7 Macquarie Place has LED lighting systems in the building but it is still using the
fluorescent lights in the parking and some other areas. Replacing these lights with LED
lighting systems can help them reduce the electricity bills as LED lights consume
approximately 50% less electricity than typical fluorescent lights. (Philips, 2016)
Potential costs: Low ($17.95 per tube) (Philips, 2016)
2. Installing sensors for lighting:
Installing the lighting sensors in the building would reduce a lot of energy which is being
wasted, even when it’s not used. As it was observed on the trip to the building,the lighting
was already on when reached the floor we were visiting. The point I’m trying to make is
that ifthe lighting sensors are installed,the lighting would be used just when it is required
and would be turned off automatically. Lighting sensors reduce the costs of lighting by at
least 15% per annum. (Reduction Revolution, 2016)
Potential costs: Low ($29.50) (Reduction Revolution, 2016)
3. Installing sensors for taps:
Typical taps are being used in the building, toilets as well as the kitchens and elsewhere.
These taps can add up to wasting a lot of water if they are not properly closed, which
happens most of the time. Installing sensors to the taps mean that the taps would only
provide water when needed and when there is no need the taps would automatically stop
providing water and nobody would have to close it tightly. It would help save the water
thus making the building more sustainable.
Potential Costs: Low ($76 and above) (Ebay, 2016)

4. Installing Airblade hand dryers in toilets:
Conventional hand dryers are being used in the building’s toilets which consume a lot of
electricity and are un-hygienic as well. Instead of using conventional hand dryers, AMP
can replace them with Airblade hand dryers which prove to be more hygienic and also
consume approximately 69% less electricitythus reducing the electricity costs and carbon
emissions as well. (Dyson, 2016)
Potential Costs: Low-medium ($1,390) (Dyson, 2016)

7. Mustafa Asrar
Retrofitting options for short to medium-term (1-5 years):
1. Suction flushing system for toilets:
The building uses normal flushing systemsin the toilets which can be replaced with the suction
flushing system which is more hygienic and saves a lot of water. This can be done slowly and
graduallyas the old systemstendto create problems,ratherthan fixingthe oldflushesthe AMP
can use the opportunitytoreplacethemwithnewsuctionflushingsystems. Waste watercanalso
be used in the conversion to energy such as waste to methane etc.
Potential Costs: Medium ($1,476.99/each) (Zoxoro, 2016)
2. Plantation and green wall on the south west face of building:
Plantation can be done inside and outside the building as well. Indoor plants can be placed at
specificareasinside the buildingwhichwouldmake the environment(airinside building)cleaner
as well as provide a betteroutlookalso.Also,greenwall can be made on the southwestface of
the buildingasthatside of the building doesn’tprovide anyview.Forexample,the othersidesof

quite essential tothe building’slocationsandthusthere’snotmuchyoucandoon the side of the

help in cooling the building as well.
Potential Costs: Medium-High ($297 per module) (Atlantis, 2016)

3. Installation of rain water tanks:
Installationof the rainwatertanksonthe roof topcanhelpsave the rainwaterinthose tanksand
then can be used for other purpose such as giving water to rooftop plantation and also to the
greenwall as well,100% of that rain watercan be usedfor thispurpose.Thiswouldthusreduce
the use of water from mains which would result in decreasing the water and electricity bills as
well.
Potential Costs: Medium ($825 and above) (Ebay, 2016)

10. Mustafa Asrar
Retrofitting options for long-term (5+ years):
1. Reviewing of the air-conditioning system:
Although the air-conditioning system of 7 Macquaire Place was upgraded a few years ago, but
still, after sometime reviewing can be done to upgrade more effective and efficient air-
conditioningsystemthatcanhelpsave moreenergyandreduce thecarbonemissionsaswell.The
costs for upgrading to the new air-conditioning system can be high but it can help benefit for
decades.
Potential Costs: High-Very High
2. Installing insulation to existing external wall:
External walls can be filled withcavity insulation through drilling. This is a long-term retrofitting
optionasittakesalotof time andcostsassociatedwithitare alsohigh.The benefitsof thiswould
include cooling down the building and thus reducing the electricity load and bill as well thus
reducing carbon emissions also.
Potential Costs: High-Very High
3. Opportunities to add structure to the building:
This mightinclude addinga fewfloorson the top of the buildingwhichmightserve the purpose
for green roofs etc. Also, it can provide more area to make it feasible for solar paneling as well.
Again, it is a long-term retrofitting option and includes high costs as well.
Potential Costs: High-Very High

11. Mustafa Asrar
Recommendations:
Various options have been provided in this report to AMP, which include short-term, short to
medium-term and long-term options as well. AMP should have a look at these options and might
selectsome of these options for the retro fitment at 7 Macquaire Placeper their budget but AMP
is strongly advised and encouraged to seek professional consultancy before commencing any
work.
