More than 80 smart meters have been installed in these 17 public buildings. The data on the used resources are automatically transmitted to the EMIS web platform, allowing for remote and real-time consumption monitoring. At the same time, the system generates alerts when energy or water consumption increases sharply. The notification is sent to the institution’s manager and other responsible persons, to ensure prompt intervention.
The beneficiaries of the project were selected together with the Chisinau City Hall. One of these institutions is Municipal Children’s Hospital nr. 1. The hospital has already insulated the walls, installed solar panels and will soon upgrade the lighting system, all these with the support of development partners and public funds.
The new energy management information system will help the institution to make savings and efficiently manage the consumption of resources, considering the continuous increase of prices, says Aliona Rotari, the director of the hospital: “The bills are now higher than usual, because of the increasing price of various energy products, and we need to make savings. However, these savings should not affect the comfort of patients who need optimal conditions to get well. We have installed six meters by which we may monitor in real-time the use of electricity, heat, hot water, and cold water. We aim to obtain efficient energy management by reducing consumption and optimizing expenditures.”
The EMIS platform allows for storing monthly consumption data and comparing energy indicators during various periods of the day, month, or year. Depending on the recorded data, the management of the institutions may appreciate when the consumption of resources has been ineffective and take action to increase the energy efficiency of the building.
“For example, some institutions may reduce the heating level during the night if their activity profile allows it. In the same way, water and electricity consumption may become more efficient. Our goal is to reduce energy consumption and provide maximum support to institutions that are interested in energy management. The energy consumption monitoring mechanism will be extended nationally and may be used for both public and private sectors. Our goal is to reduce energy consumption and support public institutions,” says Irina Apostol, EMIS Developer at Green City Lab Moldova.
EMIS was developed and launched by UNDP in Croatia in 2006, where it has been replicated in over 13,000 public buildings. Later, the EMIS model was adapted in other countries, including Bosnia and Herzegovina, and Serbia.
“If used properly, the system could help generate savings of 5 to 15%. Monitoring data on energy and water consumption may help the managers of public institutions take decisions and adopt a more efficient energy management, which will lead to savings of financial resources,” notes Alexandru Rotaru, Project Manager at UNDP Moldova.
The 17 public buildings in the municipality of Chisinau that received access to the EMIS energy consumption monitoring information system benefited from training on using the new platform and energy management principles. At the same time, the beneficiary institutions are advised by specialists of Green City Lab Moldova on how to read and interpret the data, so as identify savings opportunities.
Public and private institutions that want to use the EMIS information system to monitor electricity, thermal energy, natural gas, hot water, and cold-water consumption should contact Green City Lab Moldova.

“We are grateful and I recommend this solution to everyone. You connect heating as you want, use as much water as you need and everyone knows how much they need to pay. We have not had centralized hot water since the ’90s. But now we have hot water; we cannot even believe that we do not have to wait for the boiler to warm up. Before, after the warm water was used, we had to wait for a few hours for the water to warm up again. Now we have hot water all the time. We can even fill a bathtub,” says Svetlana, resident of one of the multi-apartment residential buildings with a modernized heating system.
Most of the multi-apartment residential buildings in Chișinău that are connected to the heating system use vertical distribution. This system does not allow apartments’ owners to regulate their heat consumption and the bills are issued based on the overall consumption, registered by the building’s thermal connector. The payment is done via the housing management entity, which divides the total amount between individual consumers, according to several criteria, including apartments’ area.
The new heating distribution system gives apartments’ owners the opportunity to adjust the temperature level, depending on their personal needs and comfort. Each apartment has its own meter that monitors consumption, based on which the bill will be issued.
“Each consumer can see his/her own daily and monthly heating consumption and adjust promptly to the necessary thermal comfort. Thus, the comfort of the family is ensured and people start to consume more responsibly,” mentions Vasile Leu, Acting General Director of Termoelectrica. The company covered the installation of individual thermal points in each of the three blocks and the modernization of the commonly used infrastructure for thermal energy distribution.
“We are supporting the change of the vertical heat distribution system to the horizontal distribution of heat. What does it mean in reality? In reality, it means that the owners of the apartments will be able to regulate the heat by themselves, which was not the reality before. This energy efficiency solution will bring savings to the owners of the apartments – up to 30%, according to our calculations,” said Andrea Cuzyova, UNDP Deputy Resident Representative to the Republic of Moldova. The United Nations Development Programme in Moldova and GEF allocated about US$90,000 for this project’s implementation.
A similar pilot project to change the heat distribution system from vertical to horizontal was implemented this year in Bălți city.
