For simplicity, the electrical load for a building or facility can also be represented by the total current (I) or the total amount of amperes. In professional field proper lighting design is very important because an under lighting arrangement will decrease the efficiency of the task for which the lightings were designed and an over lighting arrangement will result in over expenditure of the company. x�]��n�0л�B`�R�b �%��Тh��D>D6�п��l�C`"i�G�Ǘ�/��������g�w�e[��q���֝��e;�w�e��m�;�O�����t����:����ߦ�v�q:�?��ץ}ܦ������)��u���-�]�x�>n�I�PQ�FR�Ys����}���Y�Ic�Zj$��:�H*'֧I�XO5��s�����5�Ƒu��Tk��4jUk��RP {� �U�&�H��j�%�`���E���s���x2UXMޞ"����5 50 0 obj If you’d like to see updated information on this topic, please check out this recently published article, Load Calculations — Part 1. Design Loads for Residential Buildings 3.1 General Loads are a primary consideration in any building design because they define the nature and magnitude of hazards or external forces that a building must resist to provide reasonable performance (i.e., safety and serviceability) throughout the structure’s useful life. General Requirements 1-5 . Electrical calculations should be made for all SPU projects that include electrical components and should be filed in the project notebook. – President, BMC Consulting LLC . Design Loads for Residential Buildings 3.1 General Loads are a primary consideration in any building design because they define the nature and magnitude of hazards or external forces that a building must resist to provide reasonable performance (i.e., safety and serviceability) throughout the structure’s useful life. b. g” 1.
