SUSTAINABILITY IN CONSTRUCTION SITES

Waste Management in Construction Sites

Rio Verde invests in reducing waste due to losses and repairs, so that the least possible volume of waste is generated. Each project follows a waste management plan to ensure that project construction occurs in a way that presents the least impact to the environment, through actions of economy, awareness, reuse, recycling, qualification of destination and monitoring of waste disposal.

Recycled water on wheel washing

After rain, areas with exposed soil in construction sites undergo changes. The soil is transformed into mud and the great movement of machines and trucks transports this material to several points, including the surroundings of the work site.
To minimize disturbances, at construction sites, Rio Verde uses a device known as Lava Rodas (Wheel Washer), an area with a concrete bottom and effluent treatment, by means of a sand and oil separation container. The system has a reservoir that reuses water after treatment. Thus, there is a closed cycle with a reduced volume of drinking water or reused water from other systems being used to make up for losses.
In a construction sites with three towers, for example, an average of 20 trucks per day use a volume of approximately 4,000 liters of reuse water for tire cleaning.

Solar Heater

Electrical showers are great villains when it comes to saving both water and electricity, and we can feel this loss in our pockets. Lack of awareness worsens the situation because unnecessarily long showers make the water and electric bill increase considerably, not to mention the environmental losses that we have.
In some of Rio Verde’s construction sites, solar water heating is used to supply the showers of employee locker rooms. There are approximately 20 showers where the water is heated using the system, which may supply up to 200 showers/day. This represents over 6,000,000 liters of heated water during the construction period, if all the employees take a shower at work every day.

Air conditioning water system

The air conditioner, incredible as it may seem, is a water-saving solution. Air conditioning cools the environment through the passage of air through a colder element (evaporator). When it encounters a cold surface, the water present in the air condenses into drops and leaves by the drain in the device.
It is estimated that a12,000 BTU air conditioning system eliminates 300 ml of water per hour. That is, if the AC is on from 7 am to 7 pm, the total volume will be 3.6 liters.
Currently, all Rio Verde works use AC water to clean the floor, the windows and to water plants. This water does not need to be treated for those purposes and is improper for potable use.
Interestingly, we use the AC system during the season when we need water the most: summer.

Green areas over the roof

Plants, when they are over closed environments, can reduce the energy consumption of air conditioning systems, as the vegetable layer protects this environment from heat, keeping it fresh throughout the day. During the works period, Maison D’Art Enterprise implemented a green roof over the canopy of a waiting area. It was necessary to structure the roof, but investment was not great, as the wood came from reuse. Trays used for sprouts also came from materials used to construct the towers structure. Therefore, the investment necessary was acquisition of the saplings, a small amount compared to the advantages offered by the system.
