The Changing Face of HVAC Motor Control

Carl Weinschenk

The drive toward energy efficiency is changing just about everything a facility manager has to track – including HVAC motor controls. The use of variable frequency drives (VFDs) to control motors are a common approach to powering HVAC systems. A VFD, according to VFD.com, is a motor controller that uses frequency and voltage to adjust the speed   …Continue Reading


For Datacenters, Indirect Evaporative Cooling is a Cool Idea

Carl Weinschenk

Cooling datacenters is one of the big issues of the times: There are more datacenters and they are getting bigger. Keeping the servers and other equipment cool is paramount – and extraordinarily expensive. EnergyBiz this week posted a feature on indirect evaporative cooling, one of the main approaches to cooling. Bruce Baccei – the Project   …Continue Reading

The piece quotes U.S. Green Building Council statistics that buildings account for 39 percent of carbon dioxide emissions. To date, the piece suggests, the focus has been on increasing efficiency in new buildings. In addition   …Continue Reading


The Many Roads to HVAC Renewal

Carl Weinschenk

HVAC systems must be kept in optimal working order. In addition to controlling the livability of the premise, HVAC systems are key line item expenses. Keeping them running smoothly is a financial, health and even legal necessity. Though the goal is the same – fix aging and underperforming HVAC systems – there are a number   …Continue Reading


Two Projects Suggest that Cogeneration is Heating Up

Carl Weinschenk

From the conceptual standpoint, cogeneration makes a tremendous amount of sense. After all, it’s difficult to argue with the idea of meeting two needs with a single platform. The good news for proponents is that use of cogeneration – combined heat and power – is growing. Two examples of the progress that is being made are projects   …Continue Reading


Confronting the Stack Effect

Carl Weinschenk

Building managers can save a lot of money by dealing with the flow of air through the structures they oversee. A key area of concern is the stack effect (also known as the chimney effect). It is a naturally occurring phenomenon that has the potential to create great efficiencies or, if ignored, literally send money up through the   …Continue Reading


Chicago: Four Paths to Energy Efficiency

Carl Weinschenk

Chicago, the third most populous city in the United States, is host to at four significant energy efficiency initiatives. Three of the projects focus on buildings: The city of Chicago is assessing energy use in large commercial, institutional and residential buildings; the Archdiocese of Chicago is tracking energy use in its buildings; Retrofit Chicago has passed   …Continue Reading
