Kalau sustainable construction tapi

bukan untuk arsitek gimana

dong

Green Building tuh apaya??

Dicat hijau semua ajakali

Kalau Green Construction?

Kita punya keterbatasansumber daya dantekanan ekologi

Apa yang kita bangun di masa sekarang harus dapat

berlanjut di masa depan

Sustainable construction mempunyai lingkup yang lebih luas daripadagreen building, mencakup seluruh aspek pembangunan mulai dari perancangan,

pemakaian sampai daur ulang

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.

• 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

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.
