Overview
NEPLAN Gas, Water & Heating / Cooling is the modular software solution for planning, simulation, optimisation and operation of non-electrical infrastructure networks. It is designed for network types such as gas pipelines, water supply and distribution, heating and cooling systems, as well as district heating/cooling. With its intuitive graphical user interface, NEPLAN enables engineers, operators, utilities and planners to model, design, analyse and optimise these networks with precision and efficiency.
One of NEPLAN’s distinguishing capabilities is its support for integrated energy networks it is the only tool on the market that allows simultaneous simulation of electricity, gas, water and heating networks. This lets users study the interdependencies and interactions between these networks (for example, how gas-fueled heating or combined heat and power feeds into electricity, or how water cooling/heating loads affect electrical and thermal systems) in a coherent, mutual-feedback environment.
As noted, ability to model electricity, gas, water, and heating/cooling networks together. Great for planning in smart cities, multi-energy systems, district thermal networks.
You pick the modules you need (gas, water, heating/cooling) with modular add-ons such as time simulations, fire-water planning, etc.
Full modelling of flows, pressures, temperature dependencies, pump & valve behaviour, pressure losses (bends, junctions etc.), compressible/incompressible gas, etc.
GIS and map support; import/export; shared databases; web services / APIs; ability to update library data; client-server / multi-user / SQL database support.
Perform detailed, time-based simulations on very large networks to analyze their behavior over daily, weekly, or seasonal periods under varying demands and supply conditions.
