WHAT IS INNOVATION

• Innovation refers to an idea, embodied in a technology, product, or

process, which is new and creates value. To be impactful, innovations must also be scalable, not merely one-off novelties. The Strategy for American Innovation” focuses on two broad categories

• f innovation:
• Innovation to drive economic growth and address national priorities
• Institutional and public sector innovation
• ( Kent Shigetomi, Office of the U.S. Trade Representative to Apec, Lima,

Peru )

STANDARDS DRIVE INNOVATION

• Performance Based
• Facilitate Market Access
• Improve quality and Market Reputation
• Intellectual Property Rights
• Minimum Quality
• Safety Requirements
• Interoperability
• ( Standards Council of Canada)

HOUSING TECHNOLOGY RESOURCE AND EXHIBIT CENTER BUILDING USING AITECH ACCREDITED PPST

In the aftermath of Typhoon Yolanda, many new technologies were submitted to the Aitech Committee for accreditation. To date there are 66 accredited technologies. List of accredited

technologies can be found in our website : nha.gov.ph

Likewise in view of the new climatic conditions, structural standards must comply with the new parameters for

• construction. A technical working group on disaster resiiency was

formed by the NHA to arrive at new design parameters for housing.

CHALLENGES ENCOUNTERED IN USING NEW TECHNOLOGIES

• not yet so widely accepted by the public; not attuned to culture
• warranties sometimes are not assured and even the capability to do it
• n a mass scale
• builders are not well trained on the construction methodology

especially so if the don’t own the technology

• results to material wastage instead of savings
• delays in construction
• substandard or poor quality of construction
• closed systems do not allow for future expansion or use in combination

with other materials

Memorandum Circular 2016-020 : Guidelines Using AITECH Accredited and New Technologies approved on 27 January 2016. Construction Checklist/Guidelines for the following technologies, completed by January 2016

• The conduct of the Hands-On Training Seminar was created

to educate NHA technical staff and

• ther

developers/contractors

• n

the proper construction methodologies of DPWH-approved housing models with AITECH accredited technologies/systems/building materials for typhoon reconstruction projects and other NHA projects.

Hands On Training for 186 Technical personnel completed as of EO June 2016, including Iloilo for 33 personnel conducted on 29 June to 01 July 2016 done in coordination with technology proponents, to ensure proper installation and methodology Construction Checklist/Guidelines for New Technologies being applied in Typhoon Yolanda Rowhouse projects completed by EO January 2016.( defined what items should be prepared prior to, during and after construction) Continuous monitoring of performances by contractors using such technologies as a regular part of due diligence ( CPES and AITECH Monitoring Team )

• Proponents of new technologies must ensure that their products are

properly used by builders to protect their reputation and the interest of the public in general

• The proponents must allocate funds for the transfer of the technology

to end users as part of their marketing cost, and also to promote them and enable the use on a mass scale to speed up constructioN.

• Developers/Contractors must ensure that they are well versed with the

technology prior to their application to avoid construction errors/ bad construction

• Government testing centers must likewise be improved for better

quality control and calibration and must allocate funds for such improvements and conduct researches towards this end.

• APPROPRIATEFUNDS / BUDGET MUST BE ALLOCATED FOR R&D

• Integration of the resiliency principles/ guidelines on design and

construction in our building code which is presently being reviewed by the DPWH Board of Consultants and its various referral codes ( architectural, engineering/structural, sanitary, electrical and mechanical, fire, etc.)

• Review of local laws pertaining to settlements and recommend

proposals for a typhoon/earthquake code on specific areas that are disaster prone/or are in extreme environments

• Review of processes and procedures to ensure compliance to

resiliency guidelines: who will check ? Are they technically competent? Training for regulators and implementors alike is critical

• Resiliency is not just about strength of buildings but also
• n the location/choice of sites and on the way they are

planned.

• It is also about building the resiliency of communities

who are directly affected by calamities and the effects of climate change. Therefore community/housing development programs must always be geared towards this direction.

• Multi-stakeholder

participation is indeed and truly a must in any endeavor both by government and the private sector, even with the use

• f

new technologies to achieve resiliency in our buildings and communities (direction setting, program

• wnership

issues, end- user education, experts advise, policy related matters, etc.)

Government as policy maker Local government units as frontliners
