With an all-glass façade with an inverted trapezoidal form, the Faria Lima 3500 building, located in the financial center of São Paulo, is considered one of the most modern and dauntless buildings in the city, being an example of a project that united bold design, engineering and sustainability.
The project built by Tishman Speyer, designed by KOM Arquitetura, has about 25,000 m² spread over five floors. Opened in 2012, the FL 3500 has been rated AAA (triple A), with technological solutions that are entitled to one of the best and most intelligent buildings in the São Paulo State capital.
The CTE Sustainability Unit offered LEED® Certification Consulting services and commissioning for all phases of the venture, resulting in LEED Core & Shell Gold level LEED for Commercial Interior Certification, LEED EB O + M (operation and maintenance) Gold level in 2016 and Platinum level in 2019, strengthening the building’s operational performance excellence.
CTE’s consultancy for the FL 3500 hydraulic system began in 2010, with the supervision of the demolition activities of the old buildings previously on the site, in tandem with the initial design assumptions by Tishman Speyer.
The project, designed by KOM Arquitetura, supported by Moed de Armas & Shannon Architects, has unique façade characteristics that have been studied to optimize the consumption of the air conditioning system, with minimal glare damage to the surroundings.
As one of the most innovative endeavors of the time, the FL 3500 plumbing system was designed for the use of non-potable water and for storm water and grey water treatment . The series-positioned water chillers were sized to maximize operating performance by taking advantage of the equipment’s efficiency curve at its optimum points.
CO and CO 2 sensors were installed in the garage exhaust system and fancoils, respectively, to bring intelligence to the equipment operation, while enthalpy wheels optimized the external air cooling by taking advantage of the purge air temperature.
Intelligent solutions were also brought by CTE to Itaú BBA’s interior design in order to improve the sustainability assumptions adopted by the building. To this end, the washbasin faucets received 1.8 l / min aerators, increasing water consumption performance and all new bathroom facilities were designed to receive non-potable water.
In terms of energy, the office was one of the first to have most of its lighting in LED, ensuring a 10.17% reduction in installed power compared to ASHRAE. Thinking about the future of the building’s operation, several energy meters were distributed throughout the building allowing a sectored and end-use reading, i.e., separate measurement of the air conditioning system, lighting, sockets, UPS and others.
Air quality and energy efficiency were treated with balance in the interior design that incorporated dozens of CO2 sensors in the open and closed areas of the office, which monitor indoor air quality and modulate the air renewal system without overloading the room. air-conditioning system.
Interior solutions have even increased the bike rack from 35 to 96 places, meeting the employees’ demand for cleaner modes of transport.
All solutions and technologies applied in building and interior projects have been intelligently monitored and managed by Itaú’s operating team, under the advice from CTE. The team’s engagement makes the FL3500 operation a differential in the market. Plumbing systems are monitored by end use to identify faults and corrections at short intervals and to assist in identifying improvements. Similarly, the periodic performance of energy audits by CTE resulted in constant reductions in operating costs, from consumption of 336kWh / m² in 2016 to 324kWh / m² in 2018.
Waste management, like with other systems, has monthly monitoring with the mass quantification (kg) of material generated in the operation. The data, analyzed monthly, has helped to generate indicators and improvement opportunities focused mainly on reducing and also increasing the recycling potential. As a result, there was a reduction in monthly waste generation per occupant from 10.5 kg in 2017 to 8.5 kg in 2018. Also on the theme, actions of involvement with suppliers were carried out during 2017 and 2018 to replace cardboard boxes for returnable boxes, using the recipe from the recycling process in social actions.
As to the carbon dioxide sensors, installed in regularly occupied spaces, they are monitored daily by the automation team, to avoid unhealthy environments and consequent discomfort for users.
All of these actions together provide a very high employee satisfaction rate, which in 2018 reached 82%. It is sustainability bringing performance and comfort.
Energy and Atmosphere
31% economy with the reduction in consumption through the following actions:
Over 90% of the lamps used in building lighting are LED lamps.
Installation of a lighting and air conditioning automation system, enabling them to be switched on and off completely automatically.
95% of the equipment installed in the premises of the building has the Energy Star Seal, which certifies low energy consumption.
High COP and IPLV series counterflow water chillers, coupled with enthalpy wheels and CO2 sensors.
During operation, updates were made to the characteristics and operating data of all HVAC and lighting equipment in the building, so as to facilitate access to information and operational management. In addition, the operating hours of the ventilation system and fancoils were adequate due to the operation of the building’s cold water plant and enthalpy wheel.
The building’s current energy consumption is 14% better than the world average.
Water efficiency was achieved through the installation of 1.8l / min aerators in taps, double-acting basins and low-consumption urinals, associated with the use of non-potable water from air conditioning condensation, greywater treatment and storm water harvest.
In LEED OM certification, the project scores 9 out of 15 points, 1% better than the world average.
100% of non-organic waste generated by the building is sent for recycling and organic waste is sent to landfills.
Recently, based on the critical analysis of CTE-guided solid waste audits, cardboard boxes have been replaced by returnable boxes; cigarette butt waste is now processed and turned into compost for soil recovery. And plastic cups are returned to the supplier, in a reverse logistics contract, with the whole beneficiation value donated to the GRAAC institution.
