Energy Management

Energy Management aims to reduce energy consumption (electrical, diesel) for heating, cooling and production of hot water. In order to reduce energy costs, management should be provided with sufficient information and metrics that define how energy is utilized and which cost drivers are responsible for the main cost components. Therefore, it is important to establish a suitable methodology that would allow to:

  • Allocate energy costs in various energy uses
  • Calculate per unit cost of energy uses
  • Determine demand level of main energy uses

The necessary information for this analysis can be provided by a continuous monitoring system of the energy use.

The lack of an energy monitoring system, made necessary to use modeling techniques in order to estimate energy demand for various energy uses (heating, cooling and domestic hot water as well as equipment efficiencies and building losses).

The model is mainly based on the Cooling Load Temperature Difference technique, which is an established methodology developed by American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE).

The CLTD technique makes use of environmental factors such as temperature, humidity, solar irradiation, as well as building characteristics (materials, orientation, shading) in order to estimate heating and cooling loads.

We offer various alternatives evaluated on a technical and financial basis by using the outputs from energy flow analysis, techniques and best practices for energy saving.
