LOTUS (VNT-II)

Lotus-2 (VNT-II) is an OpDes Architecture second generation high-rise commercial tower; this system is exclusively built around an updated VWBS-IV (Vortex Wind Blade System) 4 technology.  With a fully integrated Wind Energy System incorporated into a more streamlined aerodynamically body that is nearly 50% more volume than its predecessor with an improved configuration that is fully designed to augment wind velocity for conversion into sustainable energy.  In addition, the system is integrated with an automated system using an array of airfoils to enhance the vessels profile in order to improve its aerodynamic flow characteristics. 


By maximizing the required air flow characteristics, ventilation and air purification systems run on virtually no energy and are built into a redundant system of chemical Co2 extractors and HRC (Humidity Reduction Cells).  Notably, the massing of the superstructure is based off a rectilinear geometry that accentuates negative pressure on the Southern facade to augment the pressure variance of the WESEAV, thus increasing a vacuum phenomenon on the posterior of its wind blades. 


The glazing of Lotus-2 was created in order to maximize daylight penetration in its core whilst increasing the productivity of the employees inside.  Numerous studies have indicated in the past that an increase in the quality and accessibility of daylight elevates the overall well-being of its occupants.   One of the key internal features of this building system is the minimization of internal walls.  This was done to facilitate free flow of air throughout the interior.  Sound is controlled by creating common and private zones that increase sound dampening materials across specified areas. In addition, passive and active systems dampen ambient noise at acceptable comfort levels to reduce the unnecessary use of decibel reducing material.
The front elevation of Lotus-2 has an added feature of an inverted V shape.  Importantly, this passive feature was added to increase the pressure variance for the WESEAV.  Naturally, the higher decks of Lotus-2 have greater levels of ambient wind pressure, implying that the extracted V helps create a directional flow of entry of air into WESEAV.   In addition, slope and material type are chosen to accentuate wind velocity, thus reducing its friction coefficient and laminar airflow.  However, by eliminating protruding mullions and variance in surface area, the glazing system of Lotus-2 can maintain a highly-streamlined geometry.  


The superstructure is designed to facilitate greater flexibility with featuring mezzanines and duplexes around the WES.  These spaces provide for the ability for interior spaces to either have double height ceilings and more extensive views and access to daylight than the regular height interior spaces.  In addition, these floors provide additional privacy by having single exclusive access for the entire floor while providing premium amenities. 
Molded and shaped by wind, Lotus-2 incorporates an air injection system known as EVAJ (Electrostatic Vaporized Air Jets) that provide additional air pressure into the WESEAV.  In addition, the wind blades of the VWBS feature a VPCD (Variable Pitch Control Device) device that alters the angle of incidence of its wind blades based on the amount of air velocity entering the wind tube.  This feature is unique in that it allows the system to adjust its surface area and angle of exposure for peak efficiency.   Created with an aerodynamic purpose of wind power utilization, it is designed for both commercial and business applications within temperate environments. In addition, the insulated glazing of VN was engineered to maximize daylight penetration into its core to facilitate healthy and productive work environments whilst simultaneously lowering wind loads and heating demands of the entire facility.


Moreover, the Base of Lotus-2 also is a commercial center.  Its primary use is to provide access to the tenant’s areas of dining and convenience, but also to create accessibility for the pedestrians below. 


Furthermore, there is a series of supplemental energy and water systems needed for the treatment of rain and gray water.  From the outset, it was understood that this system would be as a closed-loop system, where water and energy was r produced on site in accordance with the standards of GIMA (Grid Integrated for Minimal Access). The ‘Vortex effect’ refers to the increase in compression when a fluid passes through a smaller zone of geometry.   Given that it relates to other OpDes systems, its Fluid Dynamic principles are used to enhance wind energy passing through a space.  This natural phenomenon signifies the primary technology behind the VWBS (Vortex Wind Blade System).


The VWBS is able to maximize the efficiency of a WES by increasing the speed of ambient wind velocity as it meets specially treated wind blades. The Venturi effect, on the other hand, is the fluid pressure caused when compression occurs in a gas or liquid when it flows through a constricted area of pipe.  It’s a combination of Bernoulli's principle and the equation of continuity, as per which, the velocity of a gas or liquid needs to increase due to the law of Conservation of energy.  We use the same principle in our Venturi Wind Blade System.  Our patented system also maximizes the efficiency of wind energy systems by enhancing the ambient velocity of wind.

All the critical systems of the building are in Tower Operations Center located at the penthouse of Lotus-2. These areas include critical infrastructure such as emergency generators, uninterrupted power supply, automated management system, and primary computer core in addition to engineering departments and facility operations offices.  Automated systems such as remote robotics equipment is all operated from the centralized and compact location.  Heat recovery equipment are located on the upper floors of the penthouse which is capable of being fully or semi-enclosed depending on the weather conditions.  Robotic envelope maintenance systems which automatically maintain the exterior of the building are also deployed and operated from locations throughout the Tower Operations Center.
