M&E/MEP/HVAC/SYPHONIC
M - Mechanical
Mechanical systems most commonly relate to heating ventilation and air conditioning systems, but they can also relate to transportation systems such as lifts and escalators, elements of infrastructure, industrial plant and machinery, and so on.
Heating ventilation and air conditioning can be used in buildings to:
- Maintain internal air quality.
- Regulate internal temperatures.
- Regulate internal humidity.
E - Electrical
Electrical systems might include:
- Power supply and distribution.
- Information and telecommunications systems.
- Control systems.
- Security and access systems
- Detection and alarm systems
- Interior and exterior lighting.
Clearly there is a great deal of overlap between mechanical and electrical systems, with many systems including both mechanical and electrical components, hence the term M&E (mechanical and electrical).
P - Plumbing
Plumbing refers to any system that allows the movement of fluids, typically involving pipes, valves, plumbing fixtures, tanks and other apparatus.
Plumbing systems might be used for:
- Heating and cooling.
- Waste removal.
- Potable cold and hot water supply
- Water recovery and treatment systems.
- Rainwater, surface, and subsurface water drainage.
- Fuel gas piping.
SYPHONIC RAIN WATER - HARVESTING
Siphonic drainage is widely used many Industrial, Commercial and retail buildings which has clear advantages over gravity drainage.
How it all works.
The presence of air in the pipe (approx 35 liters of air to 1 litre of water in 100 mm diameter pipe ) is the fundamental principal in all gravity drainage. The inlet of water in the roof outlet produces a vortex of air.
Siphonic draingage is actually very simple in principle and all systems work in exactly the same way
