HVAC Solutions Overview

Higher Energy Efficiency and Superior Thermal Comfort

Radiant Heating & Cooling Systems can save 30 to 40 % energy compared to conventional air conditioning systems and provide enhanced thermal comfort by transferring heat through floors, ceilings, or walls instead of relying solely on air. Sustainergic Tech designs energy-efficient radiant solutions that deliver uniform temperature distribution, lower operating costs, improved indoor comfort, and enhanced energy performance for residential, commercial, and institutional buildings.

In-slab, surface-embedded, and ceiling panel system

Precision PEX piping layouts, zone manifold balance, and thermal mass optimization for floors & ceilings.

Dew Point Sensing & Condensation Control

Integrated humidity management and dew point monitoring to ensure 100% safe, moisture-free radiant cooling.

Most suitable Technology for NET ZERO Energy Buildings

Delivers highly energy-efficient heating and cooling with minimal energy consumption, helping buildings achieve Net Zero Energy goals while maintaining a comfortable and sustainable indoor environment.

Heat Pump, Chiller, Renewable Energy Integration

Seamless pairing with air-to-water heat pumps and geothermal systems to maximize overall COP.

Radiant System Configurations

Tailored Radiant Solutions for Every Building Type

Radiant Floor Systems (In-Slab / Screed)

Hydronic PEX tubing embedded directly within concrete floor slabs or screed beds. Provides high thermal storage, ideal for high-bay lobbies, luxury residences, and institutional spaces where warm/cool floors create optimal vertical temperature profiles.

Radiant Ceiling Panels & Passive Chilled Beams

Suspended metal ceiling panels or passive chilled beams with integrated copper/PEX coils. Delivers rapid cooling response and exceptional radiant absorption, perfect for commercial open-plan offices, IT hubs, and hospital suites.

TABS (Thermally Activated Building Systems)

Utilizes structural concrete ceilings and floors as thermal energy storage. Chilled or heated water circulates through structural slabs during off-peak power hours, drastically reducing daytime peak electrical demand and chiller capacity.

Radiant Wall Systems

Hydronic piping integrated into interior wall plaster or drywall panel modules. Excellent for supplemental perimeter heating/cooling, heritage building retrofits, and cleanrooms requiring strict acoustic and air velocity limits.

Thermal Efficiency

Radiant Technology vs. Traditional Forced Air

3,500x Heat Transport Efficiency

Water transports heat over 3,500 times more efficiently than air by volume, reducing circulation energy by up to 60% compared to heavy duct fans.

30 to 40 % higher energy savings

By eliminating high-velocity air blowers, radiant systems prevent draft discomfort, cold air dumping, and dust re-circulation.

Enhanced thermal comfort

Concealed floor and ceiling piping eliminates bulky air ducts, fan coil units, and floor registers, giving architects complete aesthetic freedom.

No draft , More space saving

Radiant cooling operates with higher chilled water supply temperatures (14°C–16°C vs 7°C for FCUs), enabling chillers and heat pumps to run at significantly higher efficiency (COP).

Our Process

A 5-Step Engineering & Design Roadmap

01

Thermal Load & Surface Analysis

Calculating zone-by-zone sensible cooling/heating loads and evaluating floor/ceiling surface temperature limits to prevent condensation.

02

Hydronic System Selection

Selecting optimal radiant surface configurations (underfloor, radiant ceiling panel, or TABS) tailored to architectural and thermal requirements.

03

Hydronic Loop & Manifold Design

Designing PEX loop spacing, pipe sizing, manifold location, hydraulic pressure drops, and balancing valve configurations.

04

Dew Point & BMS Integration

Integrating dew point sensors, room humidity transmitters, and 2-way modulating valves with the central Building Management System (BMS).

05

Commissioning & Balancing

Flushing hydronic loops, pressure testing, balancing manifold flow rates, and fine-tuning thermal comfort parameters.
