One of the problems is the age of many of our buildings. Take New York where many historic buildings were built in the late 19th and early 20th centuries. While the buildings themselves have great value in terms of real estate, there are enormous challenges when it comes to electrical issues.
Even if buildings were constructed with state-of-the-art electrical reticulation systems at the time, technology changes quite rapidly, and it is common to find buildings, particularly commercial buildings, that were built decades ago that don’t meet the requirements of the kind of electric loads we need today. Some of the equipment that demands specific loads include heating equipment, chillers, air handling units, lighting, and the full range of office equipment including computers and servers. Just think how times have changed. For instance, not that long ago computers and the equipment associated with them was located in centralized locations. Today, most employees have their own computers, unless they are doing menial tasks, and many have laptops that they move between various work environments. Additionally, because electric loads were essentially continuous, load profiles were reasonably predictable, in many situations operating between fixed (usually daylight) hours. Every electrical system in a building has electrical circuits that are designed to use a certain amount of electricity, but those in older buildings simply don’t meet the needs of our contemporary world. The reality is that if the wiring hasn’t got sufficient capacity for the projected load, it won’t be suitable for the intended occupancy. This means the landlord will either have to upgrade the electrical infrastructure or the prospective tenant will have to find more suitable premises. But first, it is essential to find out what the electric load will be once you move in with all your appliances and equipment. An electric load analysis or estimate will determine the maximum capacity that will be required.Our certified electrical design engineers can do electric load estimates of buildings, so that owners and landlords know in advance what electrical capacity the building offers. Of course, if the building is new, it is designed for the maximum capacity that will be required.
Whichever way round it is done, electric load estimates require a thorough analysis of everything that relates to the electrical system. Factors that impact on load include:Electric load calculations are performed in the context of the NEC and whichever building code and/or National Fire Protection Association (NFPA) code is relevant in terms of where the premises are. So, for instance, if you are in Chicago, it will be , and in New York it will be .
Even though the newly released is more up-to-date, it obviously doesn’t contain local information. When tackling calculations though, the 2020 national version is invaluable because it contains updated tables that reflect improvements that have been made in terms of energy efficiency, as well as a number of other changes that make a substantial impact. These include requirements relating to disconnects that improve safety for electrical workers and emergency responders.
In general terms, our engineers assess all the electrical phases to ensure that all the equipment listed in the electric load letter will be able to operate smoothly, without fault.One of the problems is the age of many of our buildings.
