This blog will be a quick reference on\u202fthe big three building energy codes and standards<\/strong>\u202fthat provides you with a uniform outline for new buildings and renovations. <\/p>\n\n\n\n Energy codes<\/strong>\u202fare mandatory requirements written in enforceable language by state or local governments specifying how buildings must be constructed or performed.\u202f<\/strong> <\/p>\n\n\n\n Energy standards <\/strong>are the national recommendations for constructing energy cost-effective buildings published by national organizations like\u202fASHRAE.<\/strong> <\/p>\n\n\n\n The model energy code\u202f<\/strong>is published and maintained by the International Code Council and is written in the mandatory and enforceable language.\u202f\u202fInternational Energy Conservation Code (IECC)<\/strong>\u202fis a model energy code, and before adopting the same, the governments can adopt changes to make it suitable for regional building practices. <\/p>\n\n\n\n ASHRAE 90.1, IECC, and Title 24 are considered the Big Three Building\u202fEnergy Codes and Standards<\/strong>. <\/p>\n\n\n\n ASHRAE 90.1 <\/strong>is the\u202fEnergy Standard for Buildings except for Low-Rise Residential Buildings, and the International Energy Conservation Code (IECC)<\/strong> is developed nationally. California, with an exception, uses the\u202fCalifornia Title 24<\/a>\u202fBuilding Energy Efficiency<\/a>\u202fstandard to ensure building’s energy efficiency.\u202f<\/strong>All buildings are bound to meet the energy code requirements adopted by the authority. <\/p>\n\n\n\n Devices complying with these codes ensure energy efficiency and create a sustainable environment. Products in compliance with energy codes don’t mean that they are certified to meet building energy codes. The product has the specific functionality required to be energy code compliant depending upon the space type, daylight availability, and usage.\u202f <\/p>\n\n\n\n <\/p>\n\n\n\n ASHRAE 90.1 has brought significant changes to interior lighting power allowances while modifying lighting controls requirements. Also, Commissioning requirements were added for the first time. <\/p>\n\n\n\n Significant Changes are as follows;\u202f<\/strong> <\/p>\n\n\n\n The Lighting Power Allowances are modified according to the IES recommendations, and designers can opt for the Building Area method or Space by Space method as per their choice.<\/p>\n\n\n\n A New simplified Building Area Method was introduced for buildings, strict lighting power allowance, and various control features like automatic shutoff, local manual control, bilevel control, partial-OFF lighting, and daylight-responsive dimming.\u202f <\/p>\n\n\n\n Section 9 details lighting controls like dimming and occupancy controls that are mandatory in all commercial buildings. Exterior lighting requirements mention parking garages and exterior building lights, specifying that they should be reduced by 50% according to occupancy or schedules.\u202f <\/p>\n\n\n\n \u2794 There shall be one or more readily accessible manual lighting controls in the space that controls all lighting <=10,000 sq. ft? (9.4.1.1 (a) <\/p>\n\n\n\n \u2794 Automatically shut off lights within 20 minutes of vacancy (9.4.1.1 (h)) <\/p>\n\n\n\n \u2794 Shutoff or automatically reduce lighting by at least 50 % within 20 minutes of vacancy (9.4.1.1 (g) <\/p>\n\n\n\n \u2794 None of the lighting in the space shall be automatically turned ON (9.4.1.1 (b)) <\/p>\n\n\n\n \u2794 Besides ON and OFF, lighting is either continuously dimmed or controlled with at least one step between 30% and 70%of full lighting power (9.4.1.1 (d)) <\/p>\n\n\n\n \u2794 multi-step or continuous dimming photo controls shall control the general lighting. (9.4.1.1 (e) (f)) <\/p>\n\n\n\n \u2794 At least 50% of receptacles and 25% of feeders to modular furniture shall auto-off by either schedule, occupancy sensor, and automatic signal. (8.4.2) <\/p>\n\n\n\n \u2794 Automatically record energy use every 15 minutes and report at least hourly, daily, monthly, and annually and the system must be capable of retaining data for at least 36 months (8.4.3) <\/p>\n\n\n\n The significant changes of 2021 are Increased efficiency, at least 10% over 2018 IECC, and improved useability. \u2022 For improved usability, mandatory and prescriptive labels are removed, and compliance paths are named and defined in C401.2 and R401.2.<\/p>\n\n\n\n \u2794 Increased lighting efficacy and decreased lighting power density requirements\u202f <\/p>\n\n\n\n \u2794 New provisions for automatic receptacle control\u202f <\/p>\n\n\n\n \u2794 New provisions for energy metering and monitoring <\/p>\n\n\n\n \u2794 The sensor in a zone may automatically turn ON lights upon occupancy, may activate when unoccupied but at no more than 20 percent of total power. <\/p>\n\n\n\n \u2794 Included a section covering occupancy control function in corridors (C405.2.1) <\/p>\n\n\n\n \u2794 Time-switch controls must be installed where occupancy sensors are not installed, with notable exceptions. (C405.2.2) <\/p>\n\n\n\n \u2794 General lighting in daylight zones features daylight-responsive controls that independently control the lighting, with exceptions. (C405.2.3) <\/p>\n\n\n\n \u2794 Designates control requirements for special applications like display lighting and supplemental task lighting. They must be controlled by either an occupancy sensor or time-switch control for automatic shutoff, plus a manual control that enables them to be controlled separately from the general lighting. (C405.2.4) <\/p>\n\n\n\n \u2794 An entirely new section for Parking garage lighting controls is included (C405.2.7) <\/p>\n\n\n\n \u2794 Testing and documentation (C408.3) and Energy Metering and Monitoring (C405.10) are made mandatory.\u202f <\/p>\n\n\n\n Title 24, the building energy codes for California, has notable change in 2019 version and that includes reduction in allowed interior lighting power density. Another significant change is the inclusion of healthcare facilities as a newly regulated building type and many exceptions.\u202f\u202f <\/p>\n\n\n\n \u25cf Lighting Power Density (LPD) requirements are entirely based on the use of LED lighting. <\/p>\n\n\n\n \u25cf All restrooms are required to have occupancy sensor controls. <\/p>\n\n\n\n \u25cf Enclosed areas of 100 square feet or more, with an exceeding lighting load up to .5 watts per square foot, requires multi-level rules that allow lighting levels to be adjusted up and down. <\/p>\n\n\n\n \u25cf Daylighting controls should have automatic daylighting functionality that meets specific setting, calibration, and accuracy requirements <\/p>\n\n\n\n \u25cf Energy code now covers more occupancy types. I-1 and I-2 occupancy types have been included. <\/p>\n\n\n\n Building Energy codes<\/strong>\u202fhelp to build sustainable and energy-efficient buildings. Wireless lighting controls that comply with building energy codes and standards are prerequisites for creating energy-efficient buildings. Lighting and advanced wireless lighting control significantly impact energy savings, occupant comfort, and aesthetics of the spaces. Lighting designers, specifiers, and contractors must ensure that the lighting control systems comply with energy codes and standards while meeting the occupant requirements.\u202f <\/p>\n\n\n\n We can help you build a code-compliant energy-efficient eco system.
