Building Aerodynamics

Modern tall buildings go higher and higher with the advances in structural Design and high strength materials.On the other hand, as the height and slenderness increase, buildings suffer from increased flexibility, which has negative effects in wind loading. Flexible structures are affected by vibration under the action of wind which cause building motion, and plays an important role in the structural and architectural designs. Hence, different design methods and modifications are possible in order to ensure the functional performance of flexible structures and control the wind induced motion of tall buildings.

Building Ventilation

The design of energy efficient buildings requires a balance between a good thermal performance (effective insulation, appropriate selection of heating, cooling and lighting techniques) and an acceptable quality of indoor climate (indoor air quality, ventilation rate and thermal comfort). Vast efforts have been made to improve the thermal conditions of buildings in the last decades, for example by constructing nearly perfect building envelopes and good thermal simulation tools. But knowledge of the real airflow in buildings ventilated by natural means is still lacking. To achieve an acceptable air quality and to minimise the heat losses caused by the necessary air exchange, estimation methods for the airflow are needed.

HVAC

Heating, ventilation and air-conditioning account for 30% of energy consumption in commercial buildings in India. Consequently almost all business and house-hold has the potential to realize significant savings by improving HVAC systems. Computational Fluid Dynamics (CFD) plays an important role in design of modifications in the existing HVAC systems and heat load calculation.

Smoke and fire evacuation

In design for fire and smoke emergency, a main concern is maintaining an evacuation path that is free of smoke and hot gases produced by the fire. Computational Fluid Dynamics (CFD) plays an important role in design of modifications in placing of jet fans, CO sensors, water sprinklers and devising emergency evacuation floor plan. It is proved that CFD modelling, employed correctly and interpreted carefully can be useful design tool for devising a failure proof plan.

ASET/RSET analysis

The main objective of the smoke and fire evacuation is calculate the Available safety egress time (ASET) and Required safety egress time (RSET). The empirical correlations used for calculating the ASET/RSET is often flawed due some of the data are oversimplified or ignored for this reason numerical modelling is done to predict the exact distribution of fire and flow path of smoke to safely address the design for proper evacuation.

Structural Analysis

The beams and pillars of the buildings holds the much of the total building’s weight. On the presence of occupants, these structures are exposed to varying types of loads. Over loading would disrupt the whole structure. So the buildings are performed with structural analysis in linear static loading, buckling and Aerodynamic loading to quantify the Factor of Safety and optimization of the building for strength and safety.

Seismic Analysis:

Simulations has a capability to making impossible experimental abilities to possible. Earth quakes are capable of disrupting high structures and long flow piping and are impossible to perform experiments in such circumstances. Seismic analysis helps to find the structural loading due to sudden earthquakes and random vibration on the beams and structures.
