The formula accounts for the fuel type used, since natural gas, electricity, and steam each carry different emissions factors, and electricity specifically is weighted against New York City&#8217;s average grid emissions intensity.<\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\" data-sourcepos=\"75:1-75:260;6539-6798\">Because the calculation depends entirely on accurate energy consumption data across a building&#8217;s systems, the quality of a building&#8217;s underlying metering and monitoring has a direct effect on how confidently it can report, and defend, its compliance position.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-e20adf6 elementor-widget elementor-widget-heading\" data-id=\"e20adf6\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">How can building analytics help with Local Law 97 compliance?<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-cba3130 elementor-widget elementor-widget-text-editor\" data-id=\"cba3130\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\" data-sourcepos=\"79:1-79:419;6866-7284\">Building analytics platforms support LL97 compliance by continuously tracking energy consumption and emissions across a building&#8217;s HVAC, lighting, and metering systems, rather than relying on a single annual snapshot pulled together at reporting time. This gives building owners and managers ongoing visibility into where they sit against their emissions cap, well before the May 1 filing deadline forces the question.<\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\" data-sourcepos=\"81:1-81:586;7286-7871\">Fault detection and diagnostics adds a further layer, catching the inefficiencies, an overworked air handling unit, a miscalibrated damper, that quietly push a building&#8217;s emissions upward, long before they show up as an unwelcome surprise in an annual report.
