The Bicol State College of Applied Science and Technology (BISCAST) is the only state college in the City of Naga, a secondary city in the Philippines. Naga City has partnered with BISCAST in implementing some of its nexus initiatives. The housing project in Barangay (village) Del Rosario, which commenced in 2014, was a demonstration of said partnership. Through the said project, BISCAST helped broaden and disseminate the knowledge and skills provided by GIZ technical experts in the areas of low cost housing design and resiliency.

The cooperation between the GIZ Urban Nexus and BISCAST further intensified with emphasis on integrated resource management considering the implementation of sustainable applied technologies for display, training, research, and dissemination purposes. Furthermore, BISCAST envisions full integration of the urban nexus approach into the State College Institutional Standard Procedures and Planning.

Since 2015, BISCAST has started to share how it has applied the nexus approach with regional governmental institutions such as the Partido Development Administration (PDA) and the Department of Science and Technology (DOST). In 2017, BISCAST conducted a similar activity for other higher educational institutions at the national level.



BISCAST is a government higher educational institution formally established as a state college by virtue of Republic Act 10231 in 2012. However, BISCAST’s history as a training institution can be traced as far back as 1911. To date, it is the only state college in the City of Naga, Bicol and has a mandate of providing advanced education, higher technological, professional and vocational instruction and training in the sciences, arts, education, entrepreneurship, engineering and other related courses. It is also mandated to undertake research and extension services and provide progressive leadership in its areas of specialization.

With its vision to be “the premier college for creative and innovative applied sciences and technology,” BISCAST is open to integrate the nexus approach into the State College Institutional Standard Procedures and Planning. Furthermore, BISCAST is also willing to share its experience with other institutions. With BISCAST as a cooperation partner, the GIZ Urban Nexus project has an appropriate partner not only in terms of institutional integration level but also for capacity building of instructors as well as its 4,432 students (1.Semester 2018). BISCAST also has good ties with local government institutions and barangays (villages) owing to its over 100 years of existence as a vocational and educational institution and its several programs including research, training, and extension work.


Project Description

In 2014, BISCAST supported the GIZ Urban Nexus project initially through its involvement in Naga City’s social housing project in Barangay Del Rosario. The project’s objective was to improve housing design based on the Nexus principles. In this pilot cooperation between the City of Naga and GIZ, BISCAST supported the implementation of the nexus approach in re-designing a low-cost housing system through the apprenticeship of GIZ Advisers for BISCAST architecture students. The apprenticeship was integrated in BISCAST’s on-the-job training (OJT) program.

The nexus approach was also demonstrated through the interaction of the faculty, support offices, and administration of BISCAST in the implementation of the project. Due to the project’s successful implementation including skills and technology transferred from the GIZ experts to BISCAST architecture students, further cooperation was proposed considering advanced capacity building of trainers and the implementation of sustainable technology on site. BISCAST created a Nexus Task Force which jointly developed an Integrated Resource Management Plan for BISCAST until 2018 focusing on six major areas namely:

  1. Sustainable site development plan;
  2. Eco-friendly campus project consisting of:
    Greening program including urban roof farming and landscaping program;

    1. Solid waste management; and
    2. Water conservation through installation of rainwater harvesters powered by renewable energy;
  3. Capacity building in the fields of renewable energy, energy efficiency, green architecture, energy and water management, and climate change resilient affordable housing. Including its dissemination to other academic and local government institutions;
  4. Integration of sustainable development and design principles to all four colleges curricula with focus on energy and water conservation/efficiency issues including green building standards;
  5. Energy Management including energy audit, energy conservation, and natural ventilation research; and
  6. Climate change resilient pilot housing with “passive survivability” applications.

Since the beginning of the cooperation, BISCAST has implemented several nexus activities such as natural urban roof top farming, rainwater-based irrigation system using solar power, installation of three different rainwater harvester systems, grey water treatment for urban gardening, roof top turbines for sustainable mechanical ventilation, sustainable design course for architect and engineering students and Training of Trainers on Energy and Water in the built environment.

BISCAST also piloted a model house dubbed “Climate Change Resilient Pilot Housing” (CCRPH) which was designed and built based on the principles of climate change resiliency, affordability, and green building. The CCRPH received in July 2017 the highest rating (KAMAGONG) from Philippine Green Building Initiative (PGBI) for green building standards as well as for “Climate Change Resiliency”.

BISCAST also developed “low-cost housing building design system”, which received in December 2017 “Accreditation of Innovative Technologies for Housing” (AITECH) from the National Housing Authority (NHA).


Stakeholders / Target groups

The integration of the Nexus approach and capacity building activities employ a multi level approach at BISCAST. The following diagram shows the integration of nexus into the four major BISCAST initiatives:


  • Capacity building via Training of Trainers (ToT) for instructors in tandem with curriculum development and other research projects
  • Students “learning by doing” through several applied technologies on site Extension:
  • Technical services to Naga City and other cooperation partners in the field of low-cost housing, conduct of survey on sanitation situation in selected barangays of Naga City including data analysis as well as supporting the City in the formulation of the 30-years Sustainable Urban Development Plan
  • Dissemination of nexus approach and applied technology to other state colleges and universities as well as to other institutions such as DOST and PDA (government organization representing local governments units of Partido area in the Province of Camarines Sur)

General Administrative and Support Services / Support to Operation (GASS/STO):
