Cooling & heating loads
Calculate peak and part-load demand using climate, occupancy, envelope, equipment and process information.
Engineering Services
Viraya designs coordinated heating, ventilation and cooling systems that support occupant comfort, process needs, energy efficiency and dependable operation.
Plan your HVAC project ↗Effective HVAC design starts with how a building or process will actually be used. Loads, occupancy, climate, resilience and operating hours guide every system decision.
Viraya supports commercial buildings, healthcare facilities, institutions, campuses and industrial sites with heating and cooling engineering from early feasibility through detailed design and site support. Our India and Nigeria teams coordinate plant, distribution, ventilation, power, controls and spatial requirements as one integrated solution.
For new facilities, we compare appropriate plant and distribution options against performance, maintainability and lifecycle priorities. For existing assets, we investigate capacity constraints, hydraulic performance, control sequences and energy losses to define practical upgrades with minimal operational disruption.
Calculate peak and part-load demand using climate, occupancy, envelope, equipment and process information.
Compare chillers, heat pumps, boilers, ventilation units and hybrid arrangements for the project duty.
Design air, chilled-water and heating-water networks with coordinated routing, sizing and pressure control.
Identify useful energy recovery and thermal storage opportunities that reduce peaks and avoid waste.
Develop sequences, sensor points, metering and interfaces for stable, visible and responsive operation.
Support inspections, testing, balancing and performance review so the installed system meets its design intent.
Each sector brings different comfort, air-quality, reliability and process requirements. Viraya builds the engineering response around those priorities.
Comfortable, controllable indoor environments for offices, retail, hotels and mixed-use developments.
Conditioned spaces planned around ventilation, pressure relationships, filtration and continuity needs.
Robust thermal systems aligned with production loads, equipment heat gains and operational schedules.
Scalable central plants and distribution networks for education, civic and multi-building estates.
Our workflow connects performance targets with spatial coordination, buildability, commissioning and long-term operation.
Establish loads, comfort criteria, air-quality needs, redundancy, operating hours and future allowances.
Evaluate equipment, zoning, distribution, recovery and control options against project priorities.
Resolve plant space, routes, electrical demand, drainage, structure, controls and maintenance access.
Support technical reviews, testing and commissioning so operation reflects the approved design intent.
