Electrical Sustainability Design

Our office sustainability standards ensure that all building systems are designed to optimize energy efficiency, occupant comfort, and long-term sustainability. These standards are an amalgamation of stringent sustainability codes drawn from various iterations of the National Electrical Code (NEC) and International Energy Conservation Code (IECC).

They include strategic placement of occupancy sensors for effective lighting and HVAC control, integration of daylight-responsive lighting systems, installation of controlled receptacles to reduce phantom loads, and provisions for future solar panel integration to support renewable energy goals.

Additionally, infrastructure for electric vehicle (EV) charger readiness is incorporated to accommodate the increasing demand for sustainable transportation solutions. Elaboration of these office sustainability standards follows.

Occupancy sensor controls for lighting fixtures are to be installed in every space type with the exception of designated security or emergency areas or areas that are to have specific application controls in accordance with section C405.2.5 of the IECC. Occupancy sensor controls are to be configured to automatically turn off lights within 20 minutes of all occupants leaving a space; shall be installed alongside a manual occupant control to turn off lights; and to turn on lighting to not more than 50-percent power.

Daylight sensor controls for lighting fixtures are to be installed to monitor ambient light – both electrical and daylight – and are to brighten and dim to maintain a desired lighting level. Daylight sensor controls are to be installed in daylight zones in accordance with section C405.2.3.2 of the IECC.

All receptacles installed in enclosed office spaces, conference rooms, breakrooms, classrooms, and individual workstations (including those with modular partitions) shall be split controlled with the exceptions of spaces in accordance with section C405.11.1 of the IECC.

These controls shall follow one of the following methods: time-of-day controlled, occupancy sensor controlled, or an automated signal from another control or alarm system that shall turn off receptacles within 20 minutes after determining the area is unoccupied.

The location and size of the solar-ready zone in accordance with Chapter 2 of the Model Colorado Electric Solar Ready Code or the capacity of an installed on-renewable energy system shall be verified prior to construction. Additionally, the electrical capacity and reserved physical space for circuit breakers in the main electrical service shall be verified.

EV power transfer infrastructure, electrical equipment associated with parking space type, and the electrical capacity and reserved physical space in the main electrical service panel are to be verified prior to construction.

While our office sustainability standards are rooted in high-performance design principles and informed by the latest NEC and IECC sustainability codes, they are also intentionally flexible to accommodate project-specific owner requirements and budget considerations. We work closely with stakeholders to prioritize strategies that deliver long-term value to align with both financial goals and operational needs. This approach ensures that energy efficiency and sustainability are achieved without compromising project feasibility.
