He has spent years advancing energy-efficient and water-smart solutions that help industries like cleanrooms, data centers, wineries, and greenhouses maintain precise environmental control.
Passionate about technology with real-world impact, Ido also supports sustainable agriculture initiatives and nonprofit innovation. Through this blog, he shares practical insights on HVAC advancements, indoor air quality, and the science behind high-performing environments.
Evaporative cooling lowers air temperature through water evaporation, consuming far less energy than refrigerant-based air conditioning. This guide explains how it works, covers direct, indirect, and hybrid system types, and identifies the climate and application conditions where each is most effective.
Dew point temperature is the air temperature at which water vapor condenses into liquid. This guide explains the physics, the relationship with relative humidity, and what it means for condensation control in industrial and commercial facilities.
Adiabatic cooling reduces air temperature through water evaporation without adding external heat energy. This article explains how it works, why it is significantly more efficient than steam-based systems, and where its performance limits apply.
A swamp cooler, also called an evaporative cooler, reduces air temperature by passing air across a wet surface so water evaporates and absorbs heat. This article explains how the technology works, its climate limitations, and how the same principle underlies industrial evaporative cooling systems.
An evaporative cooler is a device that cools air by converting water into vapor. This guide explains how the technology works, the main system types, and which commercial and industrial configurations are suited to large facilities.
A high dew point means more moisture in the air and a higher risk of condensation, mold, corrosion, and equipment damage inside buildings. This guide explains dew point thresholds, how they compare to relative humidity, and what they mean for facility managers and HVAC teams.
Dew point tells you the exact temperature at which moisture in the air will condense. Unlike relative humidity, it stays stable as temperatures rise and fall, making it the more reliable metric for facility engineers, HVAC designers, and anyone monitoring condensation risk.
Measuring indoor air quality requires the right sensors, an understanding of which pollutants matter most for your space, and the ability to interpret readings against established thresholds. This guide covers what to measure, which tools to use, and how to act on results.
Relative humidity can be calculated using three main methods: the dew point formula, the Magnus saturation vapor pressure approach, and the wet/dry bulb psychrometric method. This guide covers each formula with worked examples scoped to HVAC design, cleanroom sizing, and industrial humidity control.
Commercial IAQ testing requires a different approach than residential. This guide covers which pollutants to test for, how to choose between continuous monitors and lab sampling, how to interpret results against ASHRAE 62.1 and EPA thresholds, and when professional assessment is legally required.
