before the meeting time.
He should also submit any
contribution to the group
via email or phone even if
he is not present. Similarly,
when the meeting is over,
the ‘absent’ member
should be kept informed
about the progress of the
meeting and the things
that they need to follow-up
when s/he joins back in the
next meeting. This ensures
that nobody is kept ‘out of
action’.

Change the motor to most efficient one to save energy. Put one chiller on standby while working on one.

Ensure that there is a limit for the temperature of the aircon, however the temperature must still be at a comfortable temperature. Example, 24 degrees.

Reduce the amount of sunlight entering the building so that the aircon would not need to use more energy to ensure that the temperature is low enough to be comfortable.

- Install LED lights
LEDs use up to 90% less energy and last up to 25 times longer than traditional incandescent bulbs. 

- Install sensor that controls the electrical system such as occupancy sensors.
Occupancy sensors can reduce energy waste by as much as 68% and increase energy savings by as much as 60%.

- Daylighting by using steerable mirrors to direct light into areas it would not normally reach. As well, the use of optical fibers and light ducts to spread natural light through a building is currently being experimented with.
Daylighting design can save up to 75% of the energy used for electric lighting in a building.

This saves valuable fuel resources and, in turn, lowers the energy costs faced by building owners and operators.

- allows both heat (sensible) energy and moisture (latent) energy to be exchanged.
- Good ventilation is seen as vital in the wake of the Covid-19 pandemic. Enthalpy wheels make it possible to ventilate at higher levels without being restricted by prohibitive energy costs

For example, Swiss Rotors. The company uses the best possible combination of materials, components and design principles. This resulted in a heat recovery wheel that offers better performance with energy recovery efficiency of up to 87%. It also offers a large energy cost reduction than others in the market.

 -Improve the motor over the years. Example 2 to 3 years
 -Improve to class 4
 -Calculate payback
 -Changing to a more efficient motor will result in a huge save in energy as air conditioning system take up to 50% of the energy usage. Reducing the energy usage of the air conditioning system by changing the motor will definitely save lots of money. It is also cheaper than changing to whole air conditioning system and the change can be done over a few years.
