ista Middle East
ista is one of the world's leading companies providing energy services for greater energy efficiency in buildings – especially in apartment buildings and commercial properties. We make individual energy and water consumption transparent.
Making energy transparent
We help property managers, home owners and tenants all over the world to meter, visualise, bill and manage individual energy and water consumption. Today in 24 countries including China and Russia as well as the United Arab Emirates and most European markets.
As a basis for this, we use smart meter components integrated into modern remote collection technologies covering:
- cooling and heat meters,
- water meters,
- humidity and temperature meters,
- electricity meters,
- gas meters,
- as well as the relevant installation systems.
Transparency through energy data management
With our ista energy data management system, all consumption data is visualised through on an online portal or by app and made available to the user when and where they need this. Everyone becomes an independent energy manager and can individually control their consumption. With very low investment, energy, costs and CO2 can be significantly reduced – depending on individual requirements.
We achieve further efficiency gains in buildings by offering supplementary services. They include, for example our Energy Management Programmes providing energy site surveys and reduction plans (ESCO).
