Sustainable Development in Water and Energy Efficiency

The assignment emphasizes the significance of considering water and energy efficiency elements in sustainable development projects. It recommends following WELS labels for water conservation, building energy-efficient homes using NatHERS, and utilizing thermal energy storage systems like Gemasolar to address solar power intermittency issues. The references provided include various journals, books, and online sources that support the discussion.

BUSINESS REPORT

Executive Summary-
CSR is important part in company for abiding by laws and regulations towards social
responsibility should be maintained. Present report is prepared with a view to save energy and
water by using technologies. This helps HPD to develop homes by taking into consideration all
such aspects which are helpful for people of Australia in cutting down usage of resources.

INTRODUCTION
Energy and water two are important part in human's life. Present report deals with HPD
which is property developer and planning to implement 'Western Vista Development' for people.
Recommendations and findings are provided so that sustainability can be maintained in a better
manner and goals can be accomplished.
FINDINGS AND DISCUSSION
Section 1- Water Efficiency
The drought conditions are to be fought in order to provide ease to people which has
harmed in recent years particularly in southern and eastern regions of Australia. Hargron
Property Development (HPD) is successful property dealer in Perth, Western Australia which is
planning to launch 'Western Vista Development' which will provide benefits to citizens and
sustainable building will be imparted to them. The principal water saving system can be
described below-
Rainwater Harvesting-
Estimated savings per person is 24kL/year/person. In according to the climatic condition
of Perth, each homes with separate rainwater tank can be collected from roof area of
approximately 200m2 per
dwelling. This is because rains lasts for eight months in Perth. CSR responsibility will be kept in
mind by taking piping, water outlets and taps labelled as RAINWATER complying with
AS/NZS 3500:1
Plumbing and Drainage Standards.
Greywater Reuse-
Greywater diversion device will be used with automatic back-flush to provide water for
garden irrigation (Iftekhar and Fogarty, 2017). The estimated scheme for per person is
12kL/year/person. Watering saving measures will be handled and winter irrigation ban is in place
for mains water users in Perth.
Bore Water Use-
It is used where greywater is not appropriate. The bore needs to be located in non-
trafficable section of drive away and goes 30m towards down to tap in superficial aquifer. On the
other hand, estimated scheme for per people turns out to be 22kL/year/person.
Stormwater Use-

Excess rainwater will be directed to soak wells by using permeable surface and hence, it
will be directed from local shallow aquifer.
Ratings and Monitoring-
The monitoring will be done on three months basis and WELS (Water Efficiency
Labelling and Standards) needs to be strictly adhered to. This will conserve water up to a high
extent and HPD would effectively build the same. WELS encourages taking water-saving
techniques (Gabarda-Mallorquí, Garcia and Ribas, 2017).
Section 2 - Energy Efficiency
Energy Generation system-
Photovoltaic systems are vital energy system used to supply zero greenhouse gas
emission to homes at affordable price. It is helpful in managing energy production to peak loads
quite comfortably. The average cost of electricity generation is equivalent to purchasing
electricity from grid. Category of photovoltaic system falls into crystalline silicon and thin film
leading to gain maximum efficiency at home location (Gerarden, Newell and Stavins, 2017).
Wind system-
Wind systems are helpful in generating good amount of renewable energy. Australia has
more quantum of energy and can be used to save electricity, thus, reduction in greenhouse gas
emissions are achieved. HPD is required to assess the site, appropriate heights of buildings and
then launch Western Vista Development project. Right type of system, size, design and
manufacturing can be done by HPD with the help of contractor.
Batteries and Inverters-
It is used to store energy particularly when demand is more than output. Inverters can be
used to flip energy from DC to AC mains power. Circuit breakers, switch board are important for
the purpose of safety measures. Each system can be integrated to inverter and energy can be
conserved (Moore and Holdsworth, 2019).
Passive design-
In Australia, 40 % of energy is consumed in heating and cooling in households. In this
scenario to save energy, passive design is used. It takes advantage of climate for maintaining
comfortable temperature for both cooling and heating in different aspects (McGee. 2013). Good

passive design effectively locks up thermal comfort, heating and cooling bills are attained low
and as such, greenhouse gas emissions is reduced. CSR of HPD lies in the fact that the project
should be well-designed initially and then further building should be made. People will have to
make understand in various climates when to open or shut windows and adjust shading for best
results.
Rating and Monitoring system
Rating and monitoring system is to be used so as to carry out the deviations if any in the
best possible manner. In relation to this, NatHERS will be used to carry out energy rating scheme
which is star-rating system and measures thermal power performance for homes. This will help
company to conserve energy and project will be successfully accomplished abiding CSR
responsibility (Green and et.al., 2017).
Solar Power Intermittency
The solar power is not available in case of bad weather or it does not generate power at
night. Variation continues in summer and winter. For peak AC (Air Conditioning) loads in
summer as there is no presence of intermittency. While, electricity can be produced from wind
power system in winter peak loads. The situation of solar power intermittency could be resolved
or dealt with consumption pattern of people (Laslett and et.al, 2017). Thermal energy storage
system like Gemasolar can be used as it effectively bridges the gap between solar supply and
consumption at local level. Hence, HPD can deal the situation of intermittency.
CONCLUSION AND RECOMMENDATIONS
Hereby it can be concluded that water and energy efficiency are two most important
elements which needs to be taken into consideration by HPD in order to sustain according to
CSR. It is recommended that for water efficiency WELS label should be followed which
conserves water up to a major extent and firm is responsible towards environment. Energy
efficient homes should be build up by taking NatHERS which will be helpful in maintaining and
controlling energy as Australia consumes nearly 40 % of energy is consumed in heating and
cooling. Thus, solar power intermittency should be maintained with the help of Gemasolar useful
for balancing solar supply and consumption in effective manner. Thus, firm will be able to
achieve goals and will sustain in the market.
