Hotel Prodigy & Bossa Nova Mall


Bossa Nova Mall presents a new concept for the Rio de Janeiro inhabitants and visitors: shops and food operations that join a hotel, a convention center and a business center.

Located next to Santos Dumont Airport and close to VLT’s “Santos Dumont” Station, its construction was designed with state-of-the-art technology solutions that offer quality and comfort for different publics.

The multipurpose complex is formed by Bossa Nova Mall, with 6,135 m2 GLA, Prodigy Hotel Santos Dumont and SDU Corporate.

The CTE Sustainability Unit, has provided LEED® Certification Consulting services for the project and work, achieving improved use of natural resources, mitigating the environmental impact caused by buildings and providing direct economic benefit to the customer, as well as quality and comfort for the occupants.

The project

Evidence of the sustainability of projects is becoming increasingly necessary, and the existence or not of the certification may be an exclusion criterion in competitions. In addition to the environmental benefits, the certification of the projects results in the entrepreneur having higher quality in the operation phase, with significant cost reduction and maintenance gains.

Since the project phase, CTE has worked analyzing and proposing solutions that reverberate in the lower resource consumption of Bossa Nova Mall, with all the specifics that a complex like this one has. The technical solutions were designed to maximize the use of the existing structure and the reduction in the consumption of new raw materials.

To achieve this result, one of the main challenges of the consultancy is the compliance with the energy performance of the certification. In all, 3 simulations were performed to ensure not only the prerequisite but also the rational use of energy credit, with individualized solutions for the hotel, the mall and the business center. The water-cooled high-COP VRF system, coupled with the lighting efficiency that achieved the incredible 40% result in the hotel, led to an annual cost reduction of over R$ 200,000 compared to the reference model recommended by the certification, which represents an 11.2% performance.

Customer Testimonial

“The development of LEED-certified projects today is a necessity for AAA entrepreneurship. Many companies consider the LEED certification an exclusion criterion. With LEED certification, occupants become equally protagonists of sustainability as they are required to follow the standards for their office project development, thereby ensuring awareness and better use of resources. ”

The construction project of the Prodigy Hotel & Bossa Nova Mall required the implementation of a Work Pollution Control Plan, since it is a critical area, close to Santos Dumont airport, in order to minimize the environmental and nuisance impact caused to the neighborhood. Strategies were applied such as wheel washers to remove sediment from the wheels of vehicles leaving the construction site, control of dust generated during the demolition phase and the use of water spray during construction, among others. Another way of minimizing impacts generally caused by buildings was the adoption of roofing materials and open-air floors to minimize the effect of heat islands with higher solar reflectance index.

Urban mobility

The project is located on a previously developed area and has several basic services in its surroundings, just a few meters away, as well as easy access to the main roads of Rio de Janeiro, as well as bus stops, bike lanes and the Light Rail Vehicle ( VLT) in the surroundings.

Water economy

Double-flow basins, low-consumption urinals, faucets and showers with flow regulators were used. With the adoption of water-saving sanitary metals, the building obtained a percentage of 35.27%.

Energy saving

Because this is a major retrofit, passive architectural strategies become more limited, yet it was possible to replace the facade glass with one endowed with better efficiency than the old ones, thus improving the energy performance of the building.

Materials and Waste

All of the structure, walls and floors were reused, significantly reducing the consumption of new materials, as well as generating demolition waste. Regarding the purchased materials, it was possible to demonstrate the use of 10.82% of materials with recycled content such as: facade glass, aluminum frames, steel frame and steel deck, among others.

Most of the waste generated was classified as class A (recyclable waste such as concrete, cement, blocks, etc.), at the same time being the most viable destination for recycling in the city of Rio de Janeiro, resulting in a percentage of landfill waste diversion of 96.65%.

Another highlight was the incentive to the local market, where most of the new materials purchased, 46.17%, were manufactured and extracted from raw materials within 800 km of the work.

Ventilation system

It was the development of a climatization and mechanical ventilation project that met the premises of temperature, air velocity, relative humidity, among other parameters, in compliance with ASHRAE 55. In addition, 63% of the building’s occupants can individually perform internal control of the building temperature. In other shared spaces the control is performed via the supervisory system.
