About Us

Founded in 1981, and headquartered in Pune, RSK is a leading consulting firm in the field of HVAC design and also provides ancillary services including CFD analysis, smoke analysis, IES simulations, building evacuation and pressurisation analysis.

We believe in striding ahead of the industry and are constantly upgrading our service offerings in keeping with global standards and best practices – even those not mandated by local regulations.

Our Approach

Developed by our founder, RS Kulkarni, whose vast industry knowledge and experience span almost 50 years, our methodologies are rooted in the science of engineering design and backed by cutting-edge software.

Before we design the system, we conduct a meticulous, in-depth analysis of your project plans and layout. Through an iterative process with validations at every step of the project lifecycle, our team of highly qualified engineers designs an optimised, sustainable and efficient solution in line with all your defined parameters including energy, space and cost.

All through this process, we work closely with you, other consultants and equipment vendors to ensure our system integrates seamlessly with the different aspects of your project.
