The Enthalpy Wheel: The “Cheese Wheel” of Savings

by Sean Elliston, P.E. The Challenge Addressing the needs of Indoor Air Quality (IAQ) is receiving increased attention. The outdoor air brought into the building comes with a cost, and enthalpy wheels provide a solution by exchanging the energy between the building’s exhaust air and incoming outdoor air. Enthalpy Wheel BENEFITS= LOW COST, BIG ENERGY...

Green Building Certifications

What is it? Green building certifications provide a pathway for building owners to gain recognition of the emphasis on environmental management in their design. The development of Green Building Certifications began in the early 2000s with the launch of the Leadership in Energy and Environmental Design (LEED) rating system developed by the US Green Building...

Healthy Buildings

What is it? A healthy building is designed to facilitate and measure the health and wellness of its occupants. Recent studies demonstrate the negative effects of health as a result of prolonged time spent indoors. Spending long amounts of time sitting in an office is now analogous to smoking cigarettes. Updates to the LEED rating...

Daylight Harvesting

What is it? One of the more common automation systems that is often used in schools is daylight harvesting. This approach to reducing electric light when daylight is available also has the benefit of reducing energy. Typical daylight harvesting systems use photosensors to detect the amount of daylight coming in through windows or on surfaces...

Commissioning

What is it? One of the fundamental ways to ensure that a building is operating as designed is a process called commissioning. Commissioning in its most simple form is ensuring that the building systems, including mechanical, electrical, and envelope, are properly installed and tested to achieve optimal performance per the specifications and owner’s requirements1. Ideally...

MEP Engineering – Facilities alert! Is your equipment safe?

Carbon Monoxide (CO), an odorless, colorless byproduct of gas-fired heating equipment, is a toxic gas that leads to serious and potentially lethal health issues if allowed to accumulate within any building. If your facility includes natural gas furnaces, boilers, water heaters, and/or roof-top heating and air-conditioning units equipped with gas heat exchangers, there could be a risk of CO...
