EV Charging for Multi-unit Residential Buildings
EV Charging Rough-Ins During Construction
Planning for EV charging rough-ins during the construction phase sets the stage for safer and more cost-effective infrastructure. By incorporating these rough-ins early in your project, you can significantly reduce future retrofit expenses and ensure your property is ready for the growing demand for EV charging options. It’s a smart move to integrate this step right from the beginning of your construction plans [1].
What Are EV Charging Rough-Ins?
EV charging rough-ins involve preparing the necessary electrical framework to support EV chargers in the future, without actually installing the chargers right away. This method offers flexibility, helping you manage initial costs while making it easier to upgrade later. To get it right, consult a licensed electrician who can design the setup to meet local codes and standards. This proactive step not only simplifies future installations but also provides immediate cost advantages.
Save Money by Planning Ahead
By including EV charging rough-ins during construction, you can streamline the process for adding chargers later. This eliminates the need for expensive retrofits and ensures the infrastructure is already in place, saving both time and money down the road.
Stay Compliant with Codes and Inspections
Compliance is key. Make sure your project aligns with the Canadian Electrical Code and any local regulations. Work with professionals to secure permits and schedule inspections, avoiding delays or costly adjustments later. Proper planning and adherence to these requirements will keep your project on track.
Electrical Load Calculations and Panel Sizing
Once the rough-in preparations are complete, the next step is ensuring your property's electrical system can handle current and future EV charging needs. Getting the load calculations right is crucial - it helps avoid costly mistakes, safety hazards, and the need for expensive retrofits. Let’s explore how to calculate these loads and ensure a safe, scalable charging setup.
Calculating Electrical Loads for EV Charging
Evaluating the electrical load for EV chargers is a technical process that requires the expertise of a qualified engineer. This assessment determines whether your building's electrical panel and service can safely support the additional load from EV chargers [2]. The evaluation involves analysing the existing load, peak demand, and available capacity [2]. For example, a typical residential Level 2 charger draws about 7,200 watts (7.2 kW) or 30 amps. Installing four such chargers would add a total of 28,800 watts to the system [3].
This process also considers future needs, such as adding more chargers or upgrading existing ones [2]. Skipping a proper load evaluation can lead to overloaded panels, tripped breakers, unsafe conditions, and unplanned service upgrades during installation [2]. Older homes with 60- to 100-amp panels may require upgrades to support EV charging, while newer homes often come with 200-amp panels or higher [3]. It’s important to note that while a 100-amp panel can accommodate up to 42 breakers, it cannot operate all circuits at full capacity simultaneously, as per the National Electric Code [3].
Load Management and Smart Charging Systems
Smart load management systems are game-changers for EV charging. These systems distribute power intelligently, adjusting based on charging needs and available capacity, all while monitoring energy usage to prevent exceeding infrastructure limits [4]. The financial benefits are hard to ignore. By optimizing power distribution, smart systems can eliminate the need for costly service upgrades, which could otherwise run into tens or even hundreds of thousands of dollars [5].
These systems also reduce costs by "peak shaving", which lowers electricity consumption during high-demand periods. They can even enable participation in utility programs, creating additional revenue opportunities [4]. Plus, they make it easier to expand your charging capacity down the line, all while delivering ongoing savings through demand charge management [5].
Companies like Qmerit are leading the way with advanced tools like their Panel Insights and LoadCRE (Load Capacity Recommendation Engine), which use artificial intelligence to assess panel capacity and overall household load for electrification projects [3].
Proper Panel Sizing Methods
While load management helps handle demand fluctuations, proper panel sizing provides the infrastructure needed to support EV chargers. Electrical panels play a critical role in preventing overloads by distributing electricity efficiently. For instance, a Level 2 EV charger requires a 240-volt circuit and a double-pole breaker, which takes up more space in the panel [3].
Accurate panel sizing isn’t a DIY task - it requires the expertise of a licensed electrician or qualified engineer [3]. Before installing chargers, these professionals can perform a comprehensive load evaluation and calculate whether your existing panel can handle the added demand [2][3]. If your panel doesn’t have enough capacity, they might recommend an upgrade or a load-shedding solution like a load controller [3]. While panel upgrades can be expensive, they’re often necessary for older properties or those planning multiple charging stations. To minimize costs, consider using smart power management tools to optimize energy distribution across multiple chargers, potentially avoiding the need for significant electrical upgrades [2][3].

These policies act as the final piece of the puzzle, complementing the technical installations discussed earlier.
Key Components of EV Charging Policies
Access Management
Decide how tenants will use the chargers - whether through a booking system, a mobile app, or designated time slots. Clearly outline the hours of access for each tenant to avoid disputes [6][7].
Billing Structure
Choose a billing model that suits your setup. Options include charging per session, per kWh, by time spent, or a flat fee. The structure should cover costs for hardware, software, and upgrades, and may even generate some extra revenue [6][7].
Maintenance Responsibilities
Clarify who owns the equipment, who’s responsible for insurance, and how maintenance will be handled. This includes specifying repair timelines to ensure downtime is minimized [7].
Regulations, Incentives, and Return on Investment
Being aware of local regulations and incentive programs can make a big difference in the financial success of your project. In Nova Scotia, for example, building codes are increasingly pushing for EV-ready infrastructure in new multi-unit residential buildings. While specific requirements vary depending on the jurisdiction, planning ahead can save you from expensive retrofits down the road.
Nova Scotia Regulations and Incentive Programs
Nova Scotia has recently updated its building regulations to encourage the inclusion of EV charging infrastructure in multi-unit residential developments. Developers are generally required to include basic electrical preparations, such as installing conduits and ensuring electrical panels can handle future upgrades for Level 2 chargers.
