GENERAL
The Services inside a Building constitute an important facet in its construction, since they
dictate the day-to-day Comfort, Health, Safety, Security and the Operating Expense of its
inhabitants over its entire life span.
The Services have been conceptualized in close co-ordination with the Architectural,
Planning and Design Philosophy and the Structural Parameters to produce a Concept,
which is an Integrated Whole. The geographic location of the building, its orientation
and the surrounding environment have been given due consideration in working out
design details.
Conservation of Energy & Water on one hand and Optimization of Resources on the
other hand are some of the important factors which have been considered in our design.
Our inter-disciplinary expertise is effectively utilized in harnessing various emerging
technologies and we claim that we create ECO-Friendly (GREEN) Building that are
Intelligent to the changing needs of the inhabitant systems, the internal dynamics of the
Building vis-à-vis the prevalent external climatic conditions. We are always sensitive to
the Need and Social Responsibility of maintaining the ecological balance in nature.
