Paper Abstract

Stronger typhoons have been more frequent in the Western Pacific region. Typhoon Haiyan caused widespread loss of life and destruction to properties when in made landfall in the Philippines in 2013. An estimated 1.1 million homes were damaged or destroyed in the aftermath. Damage surveys show extensive roofing damage evident in most detached structures attributed to strong winds. There is a present need to evaluate the current solar panel configurations and its structural integrity for it to properly respond to extreme environmental events in the future. Using a novel Fluid Structure Interaction (FSI) approach, this study evaluated a solar panel arrangement attached to the gabled roof of a single detached building which is a typical residential building design in the Philippines. The building was subjected to typhoon strength winds in an urban environment using Computational Fluid Dynamics (CFD) analysis. A typhoon’s Atmospheric Boundary Layer (ABL) flow simulation was conducted to predict the pressure coefficient distribution around the roof and panel structure. A structural model of the solar panel support attached to the roof was then developed, and the analysis performed using FSI to predict the stresses and displacement in the structural supports and attachments. The results of the study show the weaknesses, maximum displacement and stress concentration points in the design considering the current roof parameters and panel materials. Design optimization varying the roof pitch, height, length of eaves and arrangement of the panels was conducted. A summary of design recommendations from the results was then presented for the benefit of stakeholders (urban planners, Government and the public) to aim for a better resistant infrastructure.

Corresponding author Biography

Conrad Allan Jay Pantua is currently pursuing his PhD in Sustainable energy technology in University of Nottingham in the UK. He also received his M.S in Mechanical engineering with specialization in manufacturing technology and automation from National University of Singapore in 2011. He is also a licensed mechanical engineer by profession. Engineer Pantua is currently an Assistant Professor (on leave) for the Mechanical engineering department at De La Salle University. He was also the quality assurance coordinator for the department. His primary interests are Computer aided design and simulation in product development, engineering plastics and composites, sustainable transport solutions, sustainable product development, automation and Programmable logic controller systems.

Engr. Pantua is the official safety officer and a mechanical team member of the Sikat solar car team that competed in the 2013 World Solar challenge.  He is now working with the M.E. developmental team for the design and construction of a new solar car electric vehicle that can be used in future competitions.  He is has also published several papers in product development and computational fluid dynamics simulations. He has also worked with consultancy projects with USAID and the Oscar M. Lopez center for climate resilient communities. Aside from research projects, he also has collaborated with TechnoKids for development of mechatronics and PLC instructional materials.

Prior to his appointment in De La Salle University, Engineer Pantua worked with Lufthansa Technik Philippines (LTP) from 2006-2009 as a power plant engineer under the technical services division. His primary responsibilities include performance monitoring, forecasting and engine maintenance management of PAL’s A340 and A320 fleet. During his tenure with LTP, he received several technical trainings in basic aircraft and engine, advanced engine maintenance and troubleshooting, human factors and safety.

Engr. Pantua was able to attend several conferences abroad representing LTP and also while presenting papers for DLSU. He was able to attend an intensive course in Management of Technology sponsored by the ASEAN University network (AUN-SEED net) in Tokyo, Japan last 2013.
