Green Building Facilitator

Green Building Facilitation for Measurable Sustainability Outcomes

We guide projects through sustainability planning and documentation, helping teams improve energy, water, and indoor environmental performance to meet green building targets.

Green Compliance Support with Engineering Depth

Our facilitation covers thermal and energy modelling, lux and daylight analysis, rainwater harvesting, greywater recycling, and lifecycle analysis, aligning design decisions with certification requirements and practical site execution.

Thermal and energy modelling

Simulates building energy use to improve efficiency, comfort, and operating costs.

Lux level modelling

Predicts lighting levels to ensure spaces meet visibility and compliance requirements.

Day-lighting analysis

Evaluates natural light performance to reduce glare and improve visual comfort.

Rainwater harvest and storage system

Collects and stores rainwater for reuse in non-potable building applications.

Greywater recycling system

Treats and reuses water from sinks and showers to reduce overall water consumption.

System life-cycle analysis

Assesses total cost and performance over a system’s lifespan to support better design decisions.

Innovated Green Design System

Greatians Consulting continuously advances engineering practices through innovative, energy efficient system designs tailored to Malaysiaʼs tropical climate. Each solution integrates sustainability with practicality — optimising performance, reducing energy use, and lowering lifecycle costs.

Semi-Ducted Carpark Ventilation System

Conventional carpark ventilation systems rely on extensive ductwork, increasing fan power and static pressure. Our semi-ducted system adopts shorter duct runs, enabling unidirectional airflow that maximises air velocity and reduces energy demand. This approach lowers both operational and initial construction costs.

Auto-Static Balance Duct Design

This system ensures uniform air distribution and static balance throughout the duct network, enhancing thermal comfort and air quality in large open areas such as offices and commercial spaces. The design significantly improves the energy efficiency of Variable Air Volume (VAV) systems.

High-Efficiency Closed-Loop Hot Water System (Indirect Heating)

Conventional heat pump systems suffer from fouling and efficiency loss over time due to open-loop designs. Our closed-loop configuration eliminates scaling and maintains system performance over long operation periods. With this innovation, the system achieves a Coefficient of Performance (COP) above 5, compared to below 4 in traditional designs.

By-Pass Air Handling Unit (AHU)

Underfloor Air Distribution (UFAD):
Conditioned air is supplied through raised-floor plenums, enhancing comfort, layout flexibility, and humidity control while reducing cold-feet symptoms and lifecycle costs.

Hospital Application:
Custom-designed by-pass AHUs mitigate humidity-related mould growth, maintaining indoor air quality and achieving substantial energy savings.
