WHAT IS OPTI-V

Opti-V Systems are single-phase variable refrigerant flow (VRF) heat pumps that provide heating or cooling to individual zones using an inverter-driven compressor for precise capacity control. They offer a scalable solution for multi-zone applications where limited electrical infrastructure, space constraints, and varied comfort requirements are key design considerations. Additional Opti-V benefits include:

• Fewer ductwork requirements for easier installation
• Optimized load matching for improved part-load efficiency
• Long-line length capability for greater design flexibility
• BMS compatible for streamlined system management

DESIGN BENEFITS - COST AVOIDANCE WITH OPTI-V SYSTEMS

For building projects aiming to balance performance, efficiency, and profitability, Opti-V systems are a smart investment from the ground up. Opti-V benefits include:

• Option to build additional leasable space without the need of ductwork and smaller mechanical rooms
• Slim-profile heat pump saves space, reduces install costs
• Compatible with all-electric and solar-ready designs, helping meet energy and design codes
• Reduce the need for natural gas services
• Personalized temperature control through local thermostats

Opti-V – the smart choice for developers, owners, and tenants alike

For Developers

Opti-V systems offer unmatched design flexibility especially in vertically stacked or space-constrained layouts. Consider:

• Higher lift capabilities ideal for 4 stories+
• Long refrigerant line lengths
• Minimal ductwork and smaller mechanical rooms to free up leasable square footage
• Lightweight equipment, often eliminating need for costly steel reinforcement

For Owners

Opti-V systems can deliver building owners long-term value through reduced energy consumption, lower maintenance needs, and simplified operation. Consider:

• Dedicated electrical panels for each indoor unit
• More accurate monitoring of power usage and tenant energy usage billing
• Individual zone controls reduce service calls and building-wide disruptions
• Compatible with building management platforms for streamlined oversight

For Tenants

Opti-V delivers tenants near quiet, efficient, and personalized comfort directly to each indoor zone. Consider:

• Zone-level temperature control for ideal comfort settings
• Quiet high wall indoor units – as low as 27 dBA – for intrusive-free comfort
• Reduced energy losses through the elimination of long duct runs or home-run refrigerant piping
• Supports higher MERV-rated filtration thanks to high-static indoor unit options, helping improve indoor air quality

Benefits of a low-carbon design

Buildings are responsible for up to 70% of emissions in many cities, making HVAC electrification a key strategy for climate action. All-electric systems like Opti-V can help reduce HVAC-related greenhouse gas emissions by up to 40-55%, depending on the building type and local grid. By adopting low-carbon technologies now, developers can meet evolving standards, lower energy costs, and attract sustainability-focused tenants.
