Evaluation of the efficiency of the ventilation system in an administrative building

Abstract

Facing the energy crisis in Europe and the rise in energy prices, consumers are seeking ways to more efficiently use energy and reduce its costs. In the European Union’s green agenda, one of the main goals is to aim at constructing and designing high-energy class buildings with efficiently operating heating, ventilation, and air conditioning (HVAC) and building management systems. Currently, HVAC systems consume the largest portion of energy in buildings, and in many cases, they consume more energy than planned during the design/modeling stage. Such cases occur when incorrect assumptions are made during system design, system management is unregulated, and users are not restricted in system management. The article analyzes a real administrative building and evaluates the efficiency of its ventilation systems based on long-term monitoring results. After analyzing the levels of CO2 pollution in the premises during the monitoring period, several management measures were proposed to help save energy.
