Therefore choosing whether to use IECC or ASHRAE needs to be thought of from both an Electrical and Mechanical perspective. ASHRAE 90. Even though ASHRAE 90.1 has recommended receptacle control for several revision cycles, controlling plug loads are typically the last energy conservation. Because published information (WattStopper ads and Electrical Construction and Maintenance Magazine) report that ASHRAE 90.1-2010 has been forced on the States, effective 2012. Electrical and Mechanical systems that remain largely unchanged do not need to adhere to new guidelines.

ASHRAE 90.1 PLUG LOADS CODE
As I understand it, you can use either code in either situation, it's just that IECC has more expensive mechanical requirements while ASHRAE has more expensive electrical requirements. The ASHRAE 90.12016 energy code has specific requirements for lighting controls.

Standard 90.1 2010 by Climate Zone (with Plug-and-Process Loads). Typically, in remodel situations, office buildings tend to follow the ASHRAE 90.1 because changes to the mechanical systems can be too intrusive and expensive. ASHRAE 90.12016: nLight Applications Guide About About ASHRAE 90.1 ASHRAE 90.1 is an energy code designed to reduce energy consumption. 3.1.1 Plug/ Process Loads Plug and process loads are based on ASHRAE Handbook of Fundamentals suggested values however, there are exceptions as noted below. determination each time a revised version of ASHRAE Standard 90.1 is published with. Plug-in equipment such as kitchen appliances, consumer and office electronics - Industrial process equipment with no requirements in 90.1. Based on ASHRAE Standard 90.1-2016 with state amendments. The IECC tends to steer towards new construction and has more stringent standards for mechanical systems while ASHRAE 90.1 steers more towards remodels but focuses more on lighting controls. Miscellaneous Loads Appendix G Reporting Requirements. The Engineer of record is allowed to choose the code that best suits them. LEEDTM adopts a performance-based approach and uses the ASHRAE 90.1 energy cost. As compared with the use of ASHRAE 90. There are currently two different standards for the MN Energy Code, IECC 2012 and ASHRAE 90.1. Peak loads and plug loads: Figure 4 shows the peak electrical loads for. However, the stochastic plug load model – together with a stochastic occupancy model – outperforms the simplified model in predicting the plug loads peak and distribution.The MN Energy Code is a new set of codes that focus on lighting and plug load control. Thereby, the model evaluation results suggest that the non-stochastic model provides fairly reasonable predictions of annual energy use associated with plug loads. The findings facilitate the formulation of both simplified and probabilistic office plug loads predictions methods. Using long-term observational data obtained from a continuously monitored office building in Vienna, we specifically explore the relationship between inhabitants’ presence, installed power for equipment, and the resulting electrical energy use. Given this background, the present contribution focuses on plug loads in office buildings associated mainly with computers and peripherals. Next to factors such as building fabric and construction, indoor environmental control systems, and weather conditions, the energy demand attributable to buildings’ internal heat gains resulting from inhabitants, lighting, and equipment usage also needs to be addressed. To predict buildings’ energy use, multiple systems and processes must be considered.
