Kalau sustainable construction tapi bukan untuk arsitek gimana

dong Green Building tuh apa

ya??

Dicat hijau semua aja kali Kalau Green Construction?

Kita punya keterbatasan sumber daya dan

tekanan ekologi

Apa yang kita bangun di masa sekarang harus dapat

berlanjut di masa depan Sustainable construction mempunyai lingkup yang lebih luas daripada green building, mencakup seluruh aspek pembangunan mulai dari perancangan,

pemakaian sampai daur ulang

Apakah yang dinamakan

Sustainable post-tsunami reconstruction

This master plan was developed after the 2010 earthquake and tsunami that struck Constitución, a city of 46,000 people located on the shore of the Pacific Ocean and 300km southwest of Chile’s capital, Santiago.

8.8 Earthquake Chile - Sustainable reconstruction master plan proposes a strategy to respond with

“geographical answers”

to the “geographical threats” of the earthquake and tsunami risk.

Ethical standards and social equity

Davy Sukamta&Partners Structural Engineers HOLCIM AWARDS 2013/2014

Definition – Ethical standards and social equity – People

The project must adhere to the highest ethical standards and support social equity at all stages of construction, from planning and building processes to long-term impact on the fabric of that community. The project has to provide an advanced response in terms of ethical and social responsibility.

Adherence to ethical standards in all phases of the project's life cycle.

Contributions to the formation of socially viable environments and the values of communities.

Participation of stakeholders (client, users, neighborhood, local authorities, non- governmental organizations and others).

Quality of working conditions in the suppliers' workshop, on site and during operation (compensation, safety, basic needs, gender issues).

Political transparency and correctness

Especially in poor countries, sustainable construction means building to supply urgent and basic needs: shelter, water, schools, access to goods and services, and medical care. In other countries, affordable housing is a main issue. In still others, the problem is wasteful and excessive consumption, which might be financially affordable but is irresponsible.

Leaving sufficient materials and resources for others, including future generations, is a moral duty.

Clothing factory in Sri Lanka – MAS Intimates Thurulie

This clothing factory in Sri Lanka is a visionary departure from standard approaches. It claims to be the world’s first clothing factory powered solely by carbon-neutral sources, with the payback period for the extra cost of making the building sustainable of only five years.

The health and well-being of staff is central to the design of the factory. The building offers a comfortable

The health and well-being of staff is central to the design of the factory. The building offers a comfortable, healthful, and attractive indoor environment for all users. As part of its service to employees, the plant provides bus transport to and from the factory for staff, as well as on-site meals, medical care and banking.

The production floor is divided into separate areas where works collaborate in autonomous teams, enhancing productive and employee satisfaction. The eco-factory is an ethical response to consumers who called for stronger environmental stewardship. The beautiful and stimulating environment is uplifting: the factory is a place where people are considered with respect and dignity.

Incremental housing and decentralized sewage infrastructure improve lives of urban poor

A community cluster-based sanitation system won the “Next Generation” 3rd prize for Asia Pacific in 2011. Since then, the prize money from the Holcim Awards competition was used to develop the project: to survey the site, engage with an engineer, mobilize the community and support the project author for more than a year.

The aim of the project is to improve people’s lives through the provision of sanitation which is at the core of dignity and health. The next phase of the project will involve retrofitting households to accommodate the new toilets in Savda Gherva. The aim is to implement a viable system that will become a transferable model sanitation solution for unconnected (off-grid) low-income settlements, especially suited to the context of slum redevelopment and upgrading.

Important chain to create green building

• Method of construction which consume less energy in the process

• Use recycle/renewable material whenever possible

• Produce less waste material

• Manage the site and construction equipment to prevent polluting the environment

Important chain to create green building

• Avoiding disturbance and damage to the surroundings during construction

• Avoiding waste of time and material in repair and/or rework in defect areas

• Considering the choice of materials and its impact on our earth

Produce less waste material

Make method statements and review it to avoid mistakes

Mistake is one of the biggest contributor in waste material

The importance of Planning and Quality Assurance system

PROSPERITY

• Proyek harus feasibel dan mendatangkan kedaya-gunaan ekonomi jangka panjang

• Model innovatif untuk pembiayaan

• Sumber daya finansial dalam seluruh siklus hidup proyek dan impak regionalnya

• Fleksibilitas terhadap perubahan di masa depan

• Ketahanan terhadap kondisi ekonomi

• Ekonomi sumberdaya yang diterapkan dalam konstruksi

Economic performance and compatibility

(11)

Economic performance and compatibility – Prosperity

Definition – Economic performance and compatibility – Prosperity

The project must prove to be economically feasible and innovative as far as the deployment of financial resources is concerned. Funding must promote an economy of means and be compatible with the demands and constraints encountered throughout the construction’s life span.

Innovative models for financing.

Financial resources over the project’s life cycle and their regional impact.

Flexibility with regard to future changes (user, ownership, laws and regulations).

Robustness to economic conditions (interest rates, taxes, inflation).

Economy of resources deployed in construction.

Through efficiency of design, construction, maintenance, operation, reuse, and recycling, sustainable construction seeks feasible projects that provide long-term economic benefits for owners, users, and communities. Such benefits can take many forms besides profits or lower costs, for example:

strengthening the economic base of a region, boosting the local economy, giving residents more control over their housing costs, or even giving people a financial base.

Innovative deployment of financial resources, durability, adaptability, lifecycle cost planning, “free”

low-tech natural resources, and other attributes can work together to make sustainable construction not only financially feasible but the preferred choice and a sound long-term investment in the future.

High-efficiency concrete formwork technology

The Wasteless Free-Form Formwork construction technology combines existing processes and materials in a new way to fabricate non-repetitive free-form cast-on-site concrete structures using re-usable and digitally-fabricated wax formwork. The approach enables highly accurate, complex and free-form geometries of contemporary architectural production to be fabricated at lower cost.

August 30, 2012 | Example

High-efficiency concrete formwork technology

Zurich, Switzerland The construction technology combines existing processes and materials in a new way to fabricate non-repetitive free- form cast-on-site concrete structures using re-usable and digitally- fabricated wax formwork.

The proposed technology developed by Gramazio & Kohler, Architektur und Digitale Fabrikation – ETH Zurich, is based on a concept of mass customization rather than mass production. This means that there is no inherent difference in costs whether all elements fabricated are the same or different. The technology also focuses on economic feasibility in comparison to the state-of-the-art for free-form geometries, while implementing a completely waste-less, cyclical process, meaning that production costs go down, as usage increases.

The technology enables complex and free-form geometries of contemporary architectural production to be fabricated using designs that are highly optimized in terms of material consumption, energy efficiency, and usability.
