Based on the date in Tables 1 to 3, then:

* 0375-metre cube multiplied by 20 clients multiplied by 30 days multiplied by 12 months equals 270 cubic metres. Therefore,
the annual resource consumption is 270 cubic metres.

* The conversion ratio is 1.43 kg CO2 and the annual carbon emission is 386 Kg of CO2, saving 321 kg of CO2 compared to
the current showerhead.

Eco-solution 2: - Hairdryers

The power consumption of the current hairdryer and a more
efficient brand of hairdryer was reviewed (Figure 6), and
electrical power consumption for each type of hairdryer was
measured (Figure 7).

Figure 6: Reviewing the hairdryers used at Js Salon

For the current brand of the hairdryer, CHJPRO X3,20 SOLIS
Oracle, the energy consumed over 5 minutes is 0.128 kWh,
and the energy consumed over 30 minutes is 0.768 kWh per
customer based on an average of 20 customers per day (see
Table 4), or a total of 15.36 kWh. Meanwhile, for the JMW AIR
FIT hairdryer device, the energy consumed over 5 minutes
equals 0.097kWh, and the energy consumed over 30 minutes
is 0.582 kWh per customer, based on an average of 20
customers per day (see Table 4), or a total of 11.64 kWh. The Figure 7: Measurement of power consumption for hairdryers
electricity saved per blow dry for 30 minutes is, therefore,
0.186 kWh per customer, which is 3.72 kWh per day.
