Urban Stream (CSB-II)

Designed as a legal office along the outskirts of NYC, OpDes Architecture has developed Urban Stream (CSB-II) to utilize our proprietary Hybrid System referred to as SGET (Self Generating Energy Technologies).   Urban Stream encompasses the very best in technology and design integration for an 8,000 SF, 2-Level office building with full basement and an integrated rain water cistern. 

Its basic form consists of a vaulted concrete shell configuration with integrated PV panels and VAT (Vertical Axial Turbine) to facilitate the usage of air flow around its geometry for supplemental energy.  The unique and cutting-edge design of CHB-II is premised on the utilization of systems that enhance the workplace quality of life for its employees and clients.  Key considerations entail systems that emphasize air quality, day-lighting, sound quality and sustainable energy. Interior spaces are designed to be adaptable with a customizable cellular system in order to maximize the flexibility of a versatile program.

As an energy independent system, Urban Stream is ideally suited to meet the high-performance requirements of dependable multi-phase power demands 24/7/365. Urban Stream is functionally designed around the program of a compact and scalable energy independent private consulting office.  The harmonious mix of energy is an attempt to resolve the never-ending question.  Here, Urban Stream comprises of Hybrid Systems of both wind and solar energy.  However, the emphasis here is the creation of a machine that enhances the lives of its occupants.  With the elements of light that shape its form, the beauty of photon lies in its ability of expression.   Composed of a range of diverse materials ranging from synthetic to composite, it exemplifies an extension of the urban experience to a sized scale of both specialization and accessibility. With several patent pending technologies and systems, Urban Stream solves many problems associated with scale.  Most importantly, it achieves the integration of daylight to foster productivity and vitality for the user.

The roof shell is a hardened insulated vault; its natural shape provides a natural dome like shape that accentuates the natural tendency of gravity to form a circular form, albeit different from the typical roof geometry.  One of the key advantages of its geometry is its visceral strength.  For example, as thin as an egg shell, it can support the weight of objects many times its size due to its sheer ability to diffuse energy through its curved structure.  This simple choice of this shape makes all the difference when considering the strength and durability of our buildings.  The roof shell also entails a number of unseen advantages.  For example, the inner workings of its surface allow heightened distribution of light reflected into the work pods.  As the nature of light traverses the curved waves, the curved ceiling is merely a conduit for the photon to travel.  The longitudinal slit in the shell allows solar energy from the southern exposure to wash down into the well of the building.  Strikingly, this feature helps illuminate the atrium, lower deck and stair.

The interior ribs of the shell also impart a tangible benefit.  They add rigidity to the already durably roof system and create channels for hotter air to be funneled through the vents in the roof.  In addition, they reduce the level of ambient noise, thus making the spaces quieter and creating subtle variations of light for glare reduction. One of the more peculiar aspects of this building is the protruding boxes on the southern elevation.  These Surface Nodes serve a gamut of purposes.  The inhabit the primary offices on the Urban Office and act as light box work stations for conducting reading and paper work.  In addition, the surface areas are at typical desk height level and have exclusive access to direct sunlight.  Moreover, they create areas of focused study and reading.   As opposed to typically providing shelter from the elements, the Roof Shell also permeates the Urban Stream with energy.  The Photonic skin situated on the southern exposure of the Shell is optimized with the embedment of photovoltaic cells that convert solar radiation into electricity.  Here, the surface acts as a source of energy.  Accommodating multiple uses not only make the building more efficient, but also catalyze better performance.  The Photonic Skin mimics and provides the Urban Stream with the typical characteristics of an organism.  Like an organism, it taps solar energy to help metabolize and activate inner processes.

WAF (Wind Axial Funnel), the Secondary energy system of Urban Stream, is wind powered.  The Wind Axial Funnel tracks the change in wind direction and rotates its spoiler accordingly to increase pressure optimization.  Such critical components actively participate in building energy independent designs.
