Pressurisation Analysis

Smoke inhalation is a far more prevalent cause of death than the actual fire itself. During fires, stairwells are the safest route to safety. It is important that stairwells remain as clear of smoke as possible to ensure the safety of occupants in the event of an evacuation.

A pressurization system prevents smoke from leaking past closed doors into stairs by injecting clean air into the stair enclosure in such a way that the pressure in the stairwell is greater than the adjacent fire compartment.

Stairwell pressurisation analysis helps Architects and Structural Engineers to define the right level of pressurisation – relatively high so smoke is kept out of the building and sufficiently low to enable stairwell access during an evacuation. By simulating various fire scenarios, potentially catastrophic situations can be preempted easily.

Other Solutions

HVAC Design

Our HVAC designs are optimised for energy conservation and compliant with ASHRAE and ISHRAE guidelines and complaint with National Building and Energy Conservation Building Codes.

CFD Analysis

Fluid flows simulation and modelling to analyse HVAC performance, ensuring crucial problems are identified and solutions devised even before the system is designed.

Smoke Analysis

Fire and smoke propogation simulation to understand air flow profile so architects and structural engineers can make design improvements to ensure an optimum evacuation path.

IES Simulation

Simulation modelling allows us to compare different approaches by assessing all aspects of thermal performance, from annual energy consumption to individual surface temperatures.

Building Evacuation Analysis

Simulations to determine the most optimum egress path in the event of an evacuation and models to assess threats to a safe evacuation including static and dynamic blockage points.
