Technology Meets Integration

The creation of BP’s Controls division, Integrated Building Technologies (IBT), was inspired by a trend in business tenants who seek more reliable, hi-tech office spaces. Ultimately, they ensure comfort, environmental friendliness, security and accessibility.

IBT recently finished one of many projects that consisted of a fully upgraded and implemented controls system.

The client’s set-up included glycol pumps, roof units that fed data room units and a critical controls system that stopped working. Pre-upgrade the alarms didn’t work, which made it difficult to tend to system malfunctions. The system had to be operated manually. Manual operation meant that if a pump failed, the building manager wouldn’t know until the CRAC units failed. The client also had 3 dry coolers which carried 12 fans each, totaling 36 fans. If any of these fans failed, this would cause system inefficiency. The routine of constantly traveling to the roof to verify that all systems were working, and to manually switch over lead lag controls was becoming time consuming and increasingly hazardous to the CRAC units that were fed by the glycol system.

Our IBT team provided an advanced approach to system monitoring. We replaced the existing pump controls and failed panel devices with Delta Controls. The upgrade included new panel lights, alarm horn, Delta DDC controllers and switches. With the addition of the new controls, we are now able to remotely monitor glycol fans and water temperatures for each dry cooler. The pumps are now automatically controlled for lead/lag operation and pump auto switch over.

The newly installed Delta system is a BACnet system and was integrated into the clients existing BACnet alarm monitoring system.

With these upgrades and the BACnet integration the client now receives:

• Dry cooler glycol water temperature alarms
• Fan failure alarm for glycol
• Emailed alerts to building engineer for proactive responses
• Graphics display function and problem areas with the system–a feature the client did not have in the past

Preparing for the Future

Using modern technology and trending data, we are able to predict system downtime before it would normally happen. Showing the foresight to take these preventative steps maximizes efficiency. IBT’s ability to outline potential problems before they happen is a crucial service that ensures clients’ peace of mind.

The Next Level of Controls

From HVAC lighting and access control, our IBT team will go the distance to ensure your building is fully optimized to meet your efficiency standards. Access and lighting controls foster a smart building; a smarter building reciprocates efficiency. When an occupant swipes in for arrival, controls linked to the HVAC system for their space can be triggered to reach a specific set temperature as they enter the building. This creates an increase in comfort for office staff which can translate to productivity. Our team is able to create a personalized environment for all building occupants.

HVAC Winter Preparation

| Category: Blog

winter-in-central-park-10190The heavy jackets, winter hats and gloves are making their appearances quickly. The approach of the cold season also means it’s time for preparation on your HVAC systems. Whether you’re utilizing cooling towers, a water cooled system, or a chilled water system, it’s important to make sure that they are protected from the elements produced by winter. The industry leader in the commercial HVAC industry, The BP Group takes it upon ourselves to provide you with some tips for your winter preparation.

Cooling Towers

Water Cooled systems that work during the winter months must be protected from the frigid temperatures that put equipment at risk for freeze ups.

What exactly are freeze ups? Freeze ups occur when temperatures drop below freezing and the liquid flowing through pipes without heat trace freeze. Maintaining a 40 degree set on heat trace systems prevent pipes from freezing and potentially faulting the HVAC system.

It’s also important to check the status of all systems to make sure dampers are functioning accordingly.

Mechanical Rooms

• Protected from the elements
• Room is heated
• Sprinkler head is heat traced and insulated

Building controls should be checked thoroughly to ensure proper productivity.

Protecting your assets

Employees are your assets. When it comes to mechanical equipment on the roofs of tall NYC buildings, safety is first priority. In order to protect personnel that handle equipment, make sure roof drains are clear of debris for proper drainage. Water that is not immediately drained can cause ice buildup during freezing temperatures. This makes it extremely dangerous for personnel that perform work on the roof.

These tips can ensure your HVAC system is prepared for the winter ahead. Making small adjustments can save you time and headaches in the future.
