Much of our work involves energy studies and retrofits to commercial buildings.Read More
When it comes to the Smart Grid, are you prepared? Consider two design strategies to connect buildings to the available benefits.
November 1, 2013
You’ve heard a lot of talk about the deployment of the Smart Grid. Most of the initial smart grid deployments are focused on the de-ployment of smart meters that enable utilities to gather usage information in near real time — or what they call Automated Meter Infrastructure (AMI).Read More
Is it time for an update or a full replacement? Here are some factors to think about when evaluating mechanical systems.

Often when we are evaluating or assessing an existing building, we are on the lookout for equipment and systems that are in poor condition or approaching the end of life.Read More
These units can save energy, but only if the technology is installed and operated correctly.

The application of energy recovery units allows for the ability to do total heat recovery and recover both sensible and latent heat from an exhaust air stream, using that heat to pre-condition outdoor air required for building ventilation.Read More
As always, the challenge is not a shortage of data but managing it smartly. However, the technologies and tools are evolving to meet the task.

There are many potential benefits to knowing not only how many people are in a building, but ideally where they are locatedRead More
For most buildings, it will be a question not of if, but when.

Both new and existing building projects should have lighting control provided, either as part of a standalone system or, ideally, integrated as part of the BAS. But we often find that there are many reasons automated lighting control is not provided, ranging from simple economics to frustration with the programming and support of these systems.Read More
In our data-rich world, the next big leap is just getting off the ground.

There are many elements to a BAS. Of course, the ability to control systems through direct digital control (DDC) is always a require-ment, but ideally, we expect these systems to be much more.Read More
We won’t open greater system potential until the feedback loop is closed.
