Things to take note

# data[].attributes.body
- on vs off peak
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.

Research on the energy management saving systems:
- 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.

# data[].attributes.body
Plants help to absorb sunlight and this means that there are lesser sunlight that are entering the building. This helps to lower down indoor temperature, resulting in a more cooling atmosphere and as a result there is 33% less air conditioning required, helping in saving costs

Apart from lowering indoor temperature, green wall can help in purifying the air as plants can filter CO2 and gives out O2

Brise soleii is a series of horizontal or vertical blades that can be used to control the amount of sunlight that enters the building. It can be made from a range of materials like aluminium to wood They help in breaking up the sun’s rays so that not all the sunlight is hitting the building

| Are we able to adjust the exterior of the building to have less heat landing?  How many windows are on the façade that is receiving the most sunlight?  How do we reduce exposure of the façade to the sun?  Are there any shadings features currently covering the façade that is facing the sun the most?

| Does adding shading features impede business that is going on in the building?

| Is implementing shading feature on the building expensive?

| Are there any other features other then shading that can help reduce the amount of sun from going in?

Tampines one, part of Frasers property, will form a distributed district cooling (DDC) network reducing energy consumption by 17% and carbon emissions by 18%. It will be completed by 2025

# data[].attributes.body
The project by Temasek and SP Group is one of the efforts to transform Tampines into an eco-town by 2025, in line with the Singapore Green Plan 2030. This includes Tampines 1 Building.

# data[].attributes.body
Opened in 2009, it is a retail building with over 180 retail and dining options. It opens from 10am to 10pm. It has a wide selection of F&B.

Members should have the

responsibility to inform the

rest at least 24 hours

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’.

By recycling energy from the exhaust air, enthalpy wheels reduce the burden on air-conditioning systems to provide all the energy needed to get incoming outdoor air to the desired temperature. 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.

-Change the motor to match to the perfect efficiency.
-Total efficiency = individual equipment efficiency, key thing is motor
-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.
