By Madelaine B. Miraflor W.V. Coscolluela and Associates (WVCA), founded by architect William V. Coscolluela, is going to pursue more green projects in the country moving forward as it celebrates its  50th anniversary. “Green is the direction we should be taking. We’ve only just begun here in the Philippines,” said Coscolluela. To date, some of the company's completed projects in the country include RCBC Plaza, Ayala Twin Towers, World Center, Philamlife Tower, Shell House, SM City North Edsa, SM Aura Premier, SM Megamall, Landmark Trinoma, Tutuban Center Complex, and the World Trade Center. One of the company's success green projects is The Zuellig Building, which is known for its stunning glass facade and its energy-efficient features. It showcases one architecture trend that WVCA is bent on pursuing as the company moves forward — that of creating  more “green” designs for the Philippines. The Leadership in Energy and Environmental Design (LEED)-certified building has a double-paned, low-emissivity glass curtain wall, which allows natural light to enter 90 percent of the interior office space, but also reflects infrared and ultraviolet radiation to protect those inside from sun damage. Energy consumption is lower by 15 percent compared to conventional buildings’ because of a number of factors, such as sensor-controlled lighting and a heating, ventilation and air-conditioning (HVAC) system that regulates temperature and humidity using fresh air from the outdoors. Even water consumption is reduced inside the Zuellig, as a system is in place to capture rain and condensate water, as well as recycle gray water, to be used for watering plants. Approximately 29 million liters of water is saved thanks to this system. SM Aura Premier in Taguig City and the Unilab Corporate Center in Mandaluyong City are other manifestations of WVCA’s vision for more green architecture, as both structures have been certified as LEED Gold. WVCA has around 100 staff members, around half of whom are licensed architects. The company emphasized that lack of publicity hasn’t slowed its business down for the past five decades because of what Coscolluela believes has been the key factors to his firm’s longevity, first of which is a keen sense of teamwork and responsibility. If one is surprised at Coscolluela’s low profile despite the scope of his work, it’s because the 84-year-old deliberately shies away from putting his label on his buildings.
