Brief about Low Carbon Building

What are the Low Carbon buildings ?

• Low Carbon Building is similar to the

conventional green building system which promotes uses of green technology and green habits to reduce the degradation of the environment.

• Use Carbon as metric for references to achieve the actual environment impact and not based on

points collected.

• Use UNEP SBCI Common

Carbon Metric.

Brief about Low Carbon Building

What are the Low Carbon buildings ?

• Straight forward, transparent, easy to

implement, consistance, easy to monitor since based on actual performance. Measurable,

recordable, comparable, justifiable, can be

monitor and easy to proof.

• Cheaper and affordable since it is straight forward and focus only the relevant criteria that have high impact (lower $$$/CO2 reduction cost).• Global trend- Relevant and gain popularity at international level.

FACT! Most of the Energy / CO2e emission are during the operation

phase !!

Carbon emission in a life cycle of a building

Green Technology / application in Buildings to reduce carbon foot print

-The green technology in building is mostly refer to the technology

and applications that has impact to the Energy and Environment

related to building services

a) Design : Energy Efficiency, Renewable Energy &

Water Management.

b) Office appliances

c) Operation: Energy management in the O&M.

d) Renovation / retrofits

e) Other - Paper and water recycling

- Indoor air quality.

- Solid waste management / separation

f) End users awareness

Relation between use of energy and the

environment

SELECTION OF DESIGN STRATEGIESSELECTION OF DESIGN STRATEGIES

- The design and selection of the strategies are depends ultimate design target that required to be achieved !

- Different building will have different design strategies depend on the nature and physical of the building.

- Any irrelevant measures or too expensive could be omitted. Can be justified!

- The best is to put priority strategies that have high performance impact with low or minimum cost to implement (kWh or CO2 reduction / $$$ invested)

The GEO Building: CO2 Emission

Emits = 140 ton CO2/yr

Energy saved

= 492,125 x 0.614= 302,165 kg/year CO2= 302 tones CO2/year

Green Technology & Green Practises

TECHNOLOGIES CAN BE

CONSIDERED TO REDUCE

CARBON EMISSION

(ENERGY EFFICIENCY, RENEWABLE ENERGY, WATER MANAGEMENT AND

GREEN PRACTICE)

- Daylighting

- EE lighting + task lights

- EE office equipment (laptops, LCD monitors, networked printers)

- Green IT Network, system & appliances

- Green server room, High temperature server room.

- EE air conditioning & ventilation

- Storage cooling system (minimise chillers capacity)

- Controls & Sensors (VSDs, VAVs, CO2, BMS / Energy monitoring)

- Double glazing (heat and sound insulation)

- Roof and wall Insulation (reduce outside heat gain)

- Grid connected BIPV system (Sell energy to TNB / no batteries)

- Rain water harvest system (landscape, aircond and cleaning)

-Water management, Awareness & Operation & Maintenance

Summary of Features that helps

to reduce carbon

Water Management

Reduce use of water

• Install efficient water taps to control the amount of water.• Recycle water from basin or surau for watering the landscape.• Recycle condensate water from airconditioning system for general cleaning or landscape.• Rain water harvest System for non-drinking purpose.

Efficient use of water will reduce production of treated

water

�� Reduce operation and distribution of water supply

�� reduce carbon footprint in the operation of buildings
