The Net Metropolis, 5th Ave in Philippines by OPPENHEIM ARCHITECTURE+DESIGN

February 25th, 2011 by Sanjay Gangal

First Certified “Green” Project In The Philippines.

Situated in the prime center of the country’s main CBD, The Net Metropolis was conceived as a landmark to represent the developers’ next generation of iconic and ecologically responsive buildings. The project sets new standards and helps developing Philippines’ own green building rating system.

Net Metropolis

  • Scope: 1,550,000 SF mixed-use, office/retail complex occupying a 3-acre block.
  • Master Planning/Architecture: OPPENHEIM ARCHITECTURE
  • Date: Estimated completion of 1st building, Net Lima, 2011.
  • Estimated final completion of complex : 2014.
  • Location: Bonifacio Global City, Taguig, Philippines.

Net Metropolis

The Net Metropolis superblock has 3 office towers ranging from 24 to 40 stories that rest on 6 levels of above-grade parking, and a fully-arcaded retail and parking podium enhanced by 2 amenity parks which function not only as open amenity spaces but also as landscaped focal points. Derived from a study of solar conditions and outward views, the towers are orientated so each is rotating off the other’s axis, with each subsequent structure fanning out in a dynamic and non-monotonous cascading direction. Each tower is wrapped with leading edge diagonal aluminum solar screen overlays to minimize incident solar heat gain and optimize natural light while preserving the scenic views. These screens form over sails that define the aspirational form of the towers that point to the heavens above.

The Net Metropolis “leads” the way by being the World Green Building Council’s (WGBC) sole Pilot Project for the Philippines. The WGBC promotes design, construction, and management methods that are ecologically and socially responsible, safe and healthy. More specifically it transforms internationally accepted green building practices into a national set of standards that are adapted to the local conditions and environment.

Product of a collaboration amongst some of the most reputable professionals in the industry, from the developers/investors, to the architects, engineers, consultants, project managers and constructors, The Net Metropolis has not only achieved its objectives but also created a truly unique gem.

Net Metropolis


Leading international “green” architect Chad Oppenheim was selected by top Philippine developer, The Net Group, to design the nation’s first certified green project. The Net Metropolis is the flagship pilot development of the recently created Philippine Green Building Council (PHILGBC) to answer to the local environment’s specific needs. Oppenheim, who has a growing reputation for his green design work, participated with the PHILGBC in the actual creation of the nation’s new rating system BERDE (Building for Ecologically Responsive Design Excellence) to apply to the design the first tower in the project, The Net Lima.

“As The Philippines is answering the call to go ‘Green’ in Southeast Asia, we needed a visionary who could solidify our spot at the front of the movement. Oppenheim is just that,” says Jacques Dupasquier, Chairman of The Net Group.


Oppenheim’s masterplan concept for The Net Metropolis, 5th Ave. is composed of three towers that span a 3-acre block and range from 24 to 40 stories resting on six levels of above-grade parking. The project has a clear environmental (and economical) purpose and will further balance nature and architecture by integrating two recreational parks that serve as both amenity spaces and soothing, intricately landscaped focal points. Oppenheim seeks to marry beauty and sustainability; thus, his overall design is derived from a study of solar conditions and outward views. The towers are oriented so each is rotating off the other’s axis, with each subsequent structure fanning out in a dynamic and cascading direction.

Because it’s a pilot project, Net Lima will showcase several green “firsts” in the local market. Given the intense heat of the tropical environment, the most pioneering green feature is the combination of sun shading and a high performance glass curtain wall to minimize incident solar heat gain and optimize natural light while preserving the scenic views. The tower is wrapped with leading edge diagonal aluminum solar screen overlays. These screens form oversails that define the form of the towers, all of which sharply point to the sky above. The double glazed curtain wall glass features a low-emissivity coating that rejects heat.

According to the PHILGBC, the largest and costliest energy consumer for a commercial building in the Philippines is air conditioning. The green façade of Net Lima is a strategic tool to help reduce that cost and energy consumption all year round.

For Oppenheim, whose Miami-based practice includes projects around the globe, “Intermingling and infusing our designs with natural environments is our mission in all designs we do, and that goal is coming to fruition for the first time in an authentic way for the local environment of The Philippines with this development.”

“What appeals to me the most in Chad’s design is aesthetic performance. Net Lima is going to look radically different from other buildings in the Philippines due to its sun shading and curtain wall façade. Yet this element is also key to the building’s ‘green’ efficiency,” says Rufino.

Compared to the LEED system, based in the US, BERDE answers to the ecological needs of Filipinos in their own environment. As such, The New Metropolis project leads the way in translating internationally
accepted green building practices into a national set of standards adapted to the local conditions and environment.

“As the rating systems from other countries didn’t apply to our tropical weather, laws, best practice, or realities, local industry clamored for our own green building rating system.

The PHILGBC responded by facilitating a consultative and consensus driven process to create the Philippine Green Building Rating System (BERDE). This was the best way to transform the market,” says
Christopher De la Cruz, Chairman of the PHILGBC.

“The powerful role that Net Lima plays is proof of concept for Green Building and BERDE in the Philippines. We set very high standards in the design and specification for this green office tower,” says Raymond Rufino, Executive Vice President for The Net Group.

Net Metropolis Sun Studies

– Building Envelope consisting of Sun Shading and a Full Glass Curtain Wall featuring double glazed low-emissivity glass: Reduces costs and energy use associated with A/C

– (GRP) Fiberglass fuel storage tanks with built-in leak detection for generators used during power outages: Compared to industry standard steel tanks, these tanks reduce the risk of leaks and contamination.
They also have a life span twice as long and can easily be repaired and serviced.

– Harvesting of Condensate Water from A/C: Instead of wasting the condensate water, this is collected into a separate tank to be used for landscaping, cleaning, and other needs for the building

– Cold Air Recycling: A portion of cool exhaust air is ducted to provide comfort cooling to arcade area in front of lobby

– Required all members of the Project Team to be members of the PHILGBC


This iconic structure is situated in the prime center of The Philippines’ business district, Bonifacio Global City, Taguig. The development will come to life as a 1,550,000-square-foot mixed-use, office/retail complex beginning with the completion of The Net Lima in 2011. (Final completion of entire development set for 2014.)

The Net Lima is located in the PEZA IT Zone of Taguig, the fastest growing city in the Philippines. PEZA IT Zones are attractive to investors and locators because of tax incentives.

The Net Group is already accommodating multinational companies like JP Morgan Chase, Deutsche Bank, GE, Ericsson, Lawson, Oracle, Intel, Tetra Pak, and more.


Oppenheim is entering the design phase for the second tower of The Net Metropolis 5th Ave. project, and working under the BERDE system they helped create with the PHILGBC.
