What is sustainability?

The use of global resources at a rate that allows natural regeneration and minimizes damage to the environment.

Water Saving Devices

A standard faucet may be responsible for up to 15 percent of household water use. Making the switch could help you save more than 500 gallons of water every year.

Low Flow High-Efficiency Faucet Aerators

Low Flow Water Efficient Showerheads

Dual Flush Toilet Converters

Rainwater Tanks 


Currently she uses a car when traveling from home to school and vice versa. Cars releases many harmful gases into the atmosphere and some of these gases get stuck in the atmosphere trapping heat causing more global warming.

  • Use a ferry, it saves the amount of fuel used, you reach your destination ina short period of time, and the tickets are also cheaper than what you spend on a road trip.
  • Use public transport when travel from home to school.
    • This will reach school and let out lesser fumes than your car and hence not polluting the air as much
    • It is also cost efficient as it costs lesser than the money you have to send on gas.
  • Use bicycles
    • This will help you exercise during your busy schedules and get to work
    • Cycling will help you to remain fit
    • Reduces pollution caused by transport vehicles
    • One time payment. Better and cost efficient over a long period of time

Water & Electricity

Mrs Parr’s family try their best to decrease their shower time to as low as they are possible to but unfortunately it is not low enough. Unable to change decrease the time further we recommended them to decrease their water usage in other ways. Using a washing machine, dryer, and dishwasher also affects the amount of electricity and water used.

    • Washing clothes only with a full load
      • Hand washing the clothes saves a lot of water as we will only use 2 buckets of water instead of using 56.8 to 113.6 L of water for efficient washing machines which cost much more and the older models which use about 109.7 to 170 L of water.
    • Cloth dryers use about 1800 watts and 5000 watts of electricity as it needs to continuously spin to produce energy.
      • Since Mrs Parr lives in Singapore where is a non-limited amount of sun heat produced she can hang her clothes out in the open and since she lives in a landed property she has more than enough space.
    • Just like washing machines and dryers, dishwashers waste an unnecessary amount of water and electricity.
      • An alternative would be to wash dishes with a full load as it would only have to use that much water and electricity once per load. 

Solar Panels

  • Solar panels have helped us improve our lives in many ways. Firstly we have an unlimited source of absorbed energy that can allow us to use as much electricity as we want with only an one-time payment. It does not require any fossil fuels to be burnt or turbines to spin solar panels absorb the sunlight and with a short process we have electricity.

  • Build a solar panel on the roof

    • Cost
      • On average the total cost of solar installation can be between $15,000 to $29,000 for average sized systems sized between 4kW and 8kW
    • Efficiency
      • If we take 6000 K for the temperature of the sun and 300 K for ambient conditions on earth, this comes to 95% efficiency

    Good Habits

    Mrs Parr has many good habits that other clients could use to make their lives more sustainable. Mrs Parr is a role model for everyone as she tries her best to be as sustainable as possible.

    She freezes her leftover food so that it could be used on another day.

    She strictly uses eco-friendly bags when grocery shopping.

    She has a garden where each member of her family plants a tree when they leave for vacations.

    She makes a meal plan every weekend for the week so that she does not buy too much extra food.
