Local Law 33 of 2018 is in the spotlight, as the deadline to post placards has recently passed (October 31, 2020). But, what exactly is this NYC ordinance? Local Law 33 of 2018 amended the Administrative Code of the City of New York in relation to energy efficiency scores and grades for buildings required to benchmark their energy and water consumption. All buildings over 25,000 square feet are required to display their energy grade; in a public and clearly visible location.

Follow Up: Storm Preparedness for Your Facility - Don’t Wait for the Forecast 

August, 12, 2020 at 08:00

As a follow up to my blog posted only a month ago, “Storm Preparedness for Your Facility: Don’t Wait for the Forecast”, I literally had no idea how quickly many of us on the eastern seaboard of the United States would have to heed at least some of my advice. Just as my article began, what looked like a weak tropical storm, Category 1 hurricane that often fizzles out as they move north. Well, Isaias remained a strong storm all the way up the coast, and hit the NY-NJ-CT region hard. As I write this, hundreds of thousands of customers in the region remain without power, it has been about a week.

It is evident the biggest issue in a storm’s aftermath is power failures and how to best deal with them. One of tenets of my article was to completely understand how your facility (and home) will operate on standby power. With the hot, humid weather we’ve been experiencing this summer, lack of power can create a miserable experience. My own home has a standby system, but it cannot support the central air conditioning system that I cherish. It had me scrambling for a room sized air conditioner that I knew my small generator could handle. I ultimately failed to find that small A/C unit but found a good old fashioned fan that kept me cool. In large buildings, with inoperative windows, lack of ventilation will render the building quickly uninhabitable. Luckily, power was restored to my home after two full days, 15 gallons of gasoline and lots of running around to keep things energized.

 

Storm Preparedness for Your Facility: Don’t Wait for the Forecast

Out of nowhere, the predictions start, and the weather forecaster produces an impossible to decipher series of computer generated storm tracks. You might breathe a sigh of relief when those tracks do not come anywhere near your city, or maybe you will wake up the next day to find out that all of the models have changed, and your city is now in the bulls eye of a significant storm event. 

Now you have to decide what you can do before the high winds and heavy rain hit. Or, you can start now, before the hurricane season gets into full swing and look more closely at what makes your building able to withstand Mother Nature’s onslaught.

See anything out of the ordinary? Thank you to Chris Cookingham, Project Engineer, for sharing this!

Answer: Heat exchangers use Primary flow (HxP in the image) to cool Secondary Flow (HxS in the image). However, this particular item is flowing in reverse, so it is actually doing the complete opposite. HEA was tasked with troubleshooting this item when it was developing issues after start-up had been completed and the secondary outlet continued to trip on “High HxS Out Temperature”.
