Green / Sustainable / Low Carbon Buildings

- Indoor Environment- Water Management- Material used- Site construction-

- Procurement- Operation & Maintenance- Recycling

• 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 quantitative references to

What are the Low Carbon buildings

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

• A performance based: Does not address and assess on how to design a building. Only measure and assess the actual carbon reduction.

• Straight forward, flexible, transparent, easy to implement, consistance, easy to monitor since based on actual performance. Measurable, recordable, comparable, justifiable, can be monitor and easy to proof.

What are the Low Carbon buildings

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.

b) Office appliances

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

d) Renovation / retrofits

e) Other - Paper and water recycling- Indoor air quality.- Solid waste management / separation

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 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)

Energy Management in O&M

-

Energy management practice is very crucial to maintain efficient use of energy in the operation of a building !

Most of operators do not have sence of energy management due to lack of commitment from the clients.management due to lack of commitment from the clients.

This will results most of EE and RE features installed are not properly maintained according to the design and function (waste investment money!)

Building without EE features but if highly maintain with EM practises can make building perform better.

End User Awareness

-Energy management awareness among the users are also very important!

Buildings can be design with super green technology features but if lack of end user awareness, the building would not operate awareness, the building would not operate efficiently and waste energy.

Most of operators do not have sence of energy management due to lack of awareness and commitment.

Guidelines and Code of Practice on Energy Efficiency & Renewable Energy Building

� Development and Publication of EE in Buildings Guidelinesby Ministry of Energy, Telecommunications & Post, 1989.

� MS1525 : 2001 – Code of Practise Use of Energy Efficiency and Renewable Energy for Non-residential Buildings(Revised in 2007) by SIRIM.

� Malaysia Industrial Energy Audit Guidelines, a handbook for energy auditors by KTAK, PTM and UNDP-GEF, 2003.energy auditors by KTAK, PTM and UNDP-GEF, 2003.

� Guidelines for Conducting Energy Audits in Commercial Buildings by KTAK & PTM, 2004.

� Design Strategies for Energy Efficiency in New Buildings (Non-Domestic) by KTAK, DANIDA & JKR, 2004.

� Energy Efficiency & Conservation Guidelines for Malaysian Industries by KTAK, PTM and UNDP-GEF;- Part 1 : Electrical Energy-use Equipment, 2007.- Part 2 : Thermal Energy-use Equipment (2010)

� Sustainable Low Carbon Building Performance Framework (documentation in progress) by SEDA Malaysia.

� Based on series of R&D, studies & demonstrations shows that

energy efficiency (sustainable energy) are the fundamental to

reduce operational carbon footprint in building sector.

� High EE building performance can be achieved through energy

management process during the design and also operation.

Conclusion

� Energy Efficient building is affordable if proper cost cycle analysis

been conducted (during design & operation/retrofitting)

� The building sector need EE Building assessment tools to assess

and appreciates the performance based on actual energy and

carbon reduction.

� Energy Efficient buildings have significant role on low carbon

development especially in cities / township.

� Energy Management practices to be included into the;

- Development (design & construction phase).

- Operation (O&M and monitoring phase).

� Encourage public and industry to participate in energy

management and energy monitoring activities

Way Forward

management and energy monitoring activities

(using the BCiS Portal – www.greentownship.my).

� Provide assessment for Energy Efficient buildings based on

actual energy reduction to align with national 40% carbon

intensity reduction and global direction towards carbon neutral

development (Using GreenPASS Operation).

� To develop data repository for building energy and

carbon emission (city level, State and National level).

� Appreciate and certified EE buildings (same like other

certified green buildings) and provide incentives (not

necessary in monetary).

� Propose the EE Building certifications based on actual

performance and as part of National Appropriate Mitigation

Way Forward (cont’d)

performance and as part of National Appropriate Mitigation

Actions (NAMAs), to provide uniform assessment, reportable

and verifiable.

� The government recommended to embark on Common Carbon

Metric (CCM) for various building topology for

monitoring, benchmarking and reporting annual carbon

reduction achievement.

Building Energy Index (BEI)Net Building Energy Index (Net BEI)

Gross Floor Area (GFA):Total area of all floors of a building as measured to the outside surfaces of exterior walls and including flat roofs, halls, stairways, elevator/lift shafts, attached garages / carparks (undergound/attached/indoor), porches, balconies, basements, offices but excluding voids and open/uncovered carparks.
