Enairgi – HVAC Energy Efficiency Engineering Services

All current energy efficiency modeling tools share a significant flaw: they assume that the air in each room of a building is well-mixed, which is rarely the case. In commercial buildings, it’s common to find that over 10% of energy is wasted due to inefficient air mixing. For example, in rooms with high ceilings, we’ve observed energy consumption increase by up to 50% to compensate for these inefficiencies. We have developed advanced tools that not only identify and correct these issues but also precisely quantify their impact on a building’s annual energy consumption and CO2 emissions.

We offer our services to energy efficiency consultants, mechanical engineering firms, architects, governmental institutions and commercial building owners.

Improving Sustainability through Engineered Air Distribution

Understanding and optimizing the movement of air within a room is a complex challenge. With an array of room configurations and influencing factors, predicting air behavior accurately is paramount for enhancing the efficiency of heating, ventilation, and air conditioning (HVAC) systems.

Until recently, grilles and diffusers served merely to cover openings in walls and ceilings and distribute the air in an approximate direction. Engineers lacked sophisticated tools to predict and measure air distribution performance during the design phase. CFD changes everything!

Enhancing air mixing in a room can significantly reduce energy consumption by lowering the heating or cooling load, as well as the required amount of outside air for maintaining healthy indoor environments.

Thanks to Computational Fluid Dynamics (CFD) simulations, we can now determine which diffusers will perform optimally in specific applications and quantify air distribution performance during the design phase.

Combining our expertise in air distribution with CFD, we have developed a unique procedure to evaluate the direct impact of improved air mixing on energy consumption and CO2 emissions.

Efficient air distribution represents a pathway to substantial efficiency gains at a relatively low cost. Whether for new construction or existing buildings, we are committed to helping you achieve these gains.
