External wall cladding refers to the protective or decorative layer applied to the outside of a building’s walls. It serves both functional and aesthetic purposes, providing weather resistance, thermal insulation, and a distinctive architectural look.

External Wall Cladding Systems:

Rainscreen Cladding:
  • Outer layer with an air gap behind to allow ventilation and drainage.
  • Common in high-performance buildings.
Curtain Walling:
  • Non-load-bearing cladding systems are often made of glass and metal framing.
  • Used in high-rise office buildings.

Benefits:

  • Enhances building life span.
  • Increases property value.
  • Improves thermal performance.
  • Customizable design options.

HAVC System

HVAC system stands for Heating, Ventilation, and Air Conditioning. It is a mechanical system used to provide indoor comfort by controlling temperature, humidity, and air quality in residential, commercial, and industrial buildings.

Components of an HVAC System

Heating

  • Furnace or Boiler: Produces heat using gas, electricity, or oil.
  • Heat Pump: Can both heat and cool spaces by transferring heat.
  • Radiators or Floor Heating: Distribute heat within rooms.

Ventilation

  • Air Handling Units (AHU): Circulate and regulate air.
  • Ductwork: Network of passages to deliver and remove air.
  • Exhaust Fans: Remove stale air, smoke, odors, or moisture.
  • Filters: Trap dust, pollen, and contaminants

Air Conditioning

  • Chillers: Used in large buildings to produce cold water for cooling.
  • Split Units or Packaged Units: Common in smaller buildings.
  • Condensers & Evaporators: Key components in cooling cycle.
  • Refrigerant: The fluid that absorbs and releases heat.
