As one of Metro Manila’s premier office address, GLAS emerges as an icon of world-class design and sustainable development. This 42-storey all-glass tower integrates copious innovations on architecture, construction, and maintenance that lend its status as one of the most prominent high-rises in the nation.

From entering the site through its high grand lobby with an 8.5 meter-high ceiling and pristine indoor lighting, captivated audiences are braced to behold the elegance and wonderment that exceeds conventions from average office buildings. Every space on this 42-storey edifice offers a hospitable ambience over the bustling Ortigas skyline.

The designers envisioned an illuminating, towering gem that stands out over the looming skyline.

Yet, the prestige of this cutting-edge premier development exceeds from its peripheries, most notably its recognizable all-glass contour and groundbreaking green features. Each component is intricately mounted to honor its essential elements – light, space and technology – and transcend office building standards in the country.

But the demand for office structures at a post-pandemic period is to represent as a bastion of sustainability. The prominence of GLAS through its PEZA and LEED Platinum certifications proves that cutting-edge design and sustainable technologies are the pillars of a popular green structure.

Witness how the elements of light, space and technology transform GLAS into an icon of sustainable architecture.

Particular attention goes to the lighting that highlights that signature of the cutting-edge all-glass tower.

The Double-Glazed Triple Low-E Glass

Placement of the triple low-E glass starts on the pane with the layers are fixed.

Double-glazed triple low-E glass windows defines the tower’s green and sleek dynamism. The 32 mm-thick insulated glass unit is comprised of two 10 mm-thick fully-tempered sheets with a 12 mm airspace in-between. The floor-to-ceiling height of the windows is purposed for natural light to permeate to the interiors and block heat from entering.

On its installation, each glass surface is glazed with low-emissivity coating, serving to limit the emission of heat energy. Meanwhile, the lobby is powered with low-iron glass panels, measured with 8.5 m. x 1.5 m., 15 mm. thickness to increase the dispersal of natural light and provide crystal-clear views of the outside.

For its ambiance, the low-E glass enables temperature to be balanced, and the gap between the panes insulates the heat as it penetrates towards the tower interiors. Condensation over the windows is reduced, and the balanced temperature within the low-E glass serves to mitigate the costs of heating, ventilation, and air conditioning.

For the frit patterns, its diamond-shaped outlines – taking semblance of a cut gem – cover the side portions of the tower to block any obstruction and maintain its purity. Through its ingenuity, the glass technology provides a representation for the powerful profile for GLAS.

The process of manufacturing laminated glass involves intricate inspection of each component.

The LED Lights

During the nighttime, the tower is lit up, making its iconic contour recognizable over the skyline. With cobalt-blue LED lighting installed on the tower’s fringes, the tower’s shape emphasizes its posture as an exemplar of architectural lighting.

Like the interior lighting, the LED installation uses cost-efficient and energy-saving measures, while still giving the iconic splendor that GLAS is known for.

The Hypersized Common Areas

Space plays a vital role over the tower’s ambiance. They all serve to provide ample spaces for social distancing, breathing rooms and seamless pedestrian traffic, all to manage tenant safety.

The 4 meter-wide entryway ushers in pedestrians to five high-speed elevators. Passersby first pass through the turnstiles. A segregated messenger entry and a processing area lead occupants to their desired destination. And the lift lobbies provide the most accommodating and protected spaces, with manganese metal accents defining the embellished tone.

The Floor-To-Ceiling Height

Every corner in GLAS is bolstered by its slab-to-slab heights that highlight its pristine brilliance. Normal office floors contain a height of 4.0 meters, with a clear ceiling height at 2.80 meters. The grand lobby stands with an 8.5 meter-high ceiling. Though, both allow an even distribution of light to the spaces.

Along with the tower’s strategic orientation, the slab-to-slab height helps optimize the tower’s cost-efficient, green-based measures. Additionally, the silver stone finishes add to the tower’s distinct color palette.

Several touches in the grand lobby are fitted to complete its luxurious entrance.
The monochromatic undertones serve as the ambient motif for the tower.

The Marble Stoning

The grand lobby holds an expanse of smooth stone floor veining that highlight GLAS’ elegant design. The lift lobbies are adorned with a 2” slab inset of an Armani Stone floor finish. The baseboards are embellished with grey emperador stone slabs. And the high grand lobby’s staggering stairway are adorned with panda marble veining and razor-sharp lighting.

The floor finishes and the marble slabs are laid, unblemished and prepared, linking to create an impression of wide-open spaces for social distancing.

The Candescent Ambiance

The grand lobby gives a luxurious ambiance that complements to GLAS’ pristine brilliance.

Its 8.5 meter-high ceiling, together with the low-e glass windows, utilizes the distribution of natural light, for energy conservation. The natural stone flooring – comprised of Armani beige and grey emperador finishes – borrows from the gray undertones of the tower.

The upper levels employ the same candescent flooring, giving a subtler, more optimal effect. Tones of silver – from smoky ocean to new Turkey grey – surround the 8.5 meter-high columns, bringing the illusion of light refraction through a gem.

The top-notch glass technology is key to achieve the prism-like lighting within GLAS.
The common areas also reflect this lighting as a touch of the tower’s grandiose luxury.

The Hotel-Grade Finishes

Hotel-grade finishes succeed on the elegant ambiance of the tower. At the first step on the lobby, entrants are immersed into a remarkable ambiance that baits and switches their expectations for a green office tower.

From the lobby concierge to the core bathrooms, natural stone finishes maintain a Class A standard. The counters themselves use one continuous marble slab to provide its sleek design. And the mirrors in the latrines mimic the geometric patterns that are strewn across the building.

The Security Protocols

Innovative sustainability in GLAS extends to its rigorous security features. As a stringent measure, employees and visitors go through a screening process through Lenus, an all-in-one anti-virus compact device with an automatic facial recognition, temperature checker and sensor-type alcohol dispenser.

Lifts are also equipped with Plasma Air Purifiers that eliminate air pathogens. And with add contactless features, like the Destination Oriented Allocation System (DOAS) component in the elevators, the tower prioritizes the exclusivity, pedestrian traffic and protection of the tenants.

Guests inquire first in the concierge for security clearance.

The LED Screen

GLAS’ iconic larger-than-life LED screen serves as a platform for local artists and other vendors to showcase their 3D artwork.

The indoor LED screen is one of GLAS’ main centerpieces. Standing at 6m x 21m, the display hovers over the reception desk, positioned adjacent to the passageway and escalator to the elevators to greet passersby of its larger-than-life LED projection, which uses less energy than other LED screens.

The framework of the striking display blends with the grand lobby’s pristine welcome and makes it visible through the low-iron, SGP laminated glass panels for outsiders. For every projection, it completes the grand welcome that entrants can expect from the larger-than-life images.

Setting a New Architectural Benchmark

Every breakthrough that GLAS achieves is rooted from the expertise, the uniformity and the principles that one of the most innovative architectural practices in the Philippines demonstrates since its inception. Pursuing innovations, specializations and services for a wide range of projects, ASYA lives by its governing philosophy “Design with Purpose”.

For the construction of this revered design-and-build project, ASYA integrates its identity to several exceptional qualities of GLAS.
