Electrification Isn’t All or Nothing: How To Plan Your Building’s Journey 

For many New York City building owners, electrification has become one of the most talked-about paths to Local Law 97 (LL97) readiness. But while the term gets used often, it is also widely misunderstood. 

Electrification is not a one-size-fits-all mandate, nor is it the only route to carbon reduction. For many buildings, the smartest path forward is not an immediate all-in conversion; it is a Strategic Decarbonization Plan (SDP) built around phased investments, operational improvements, and strategic upgrades that align with each building’s infrastructure, capital timeline, and long-term goals. 

Start With the Building You Have 

One of the biggest misconceptions around electrification is that buildings need to immediately replace all fossil fuel systems with electric heat pumps or full electric HVAC systems. 

In reality, every building starts from a different place, and every building’s path is going to look different.  

A newer property with hydronic heating or centralized chilled water systems may be well-positioned for faster electrification. A pre-war steam-heated multifamily building with occupied units and aging infrastructure may require a much more measured path. 

That is why successful decarbonization planning begins with questions like: 

  • What systems are already in place? 
  • What equipment is nearing end-of-life? 
  • What carbon exposure exists in 2030 and beyond? 
  • What capital projects are already planned? 
  • What level of disruption is realistic for tenants or occupants? 

Without that baseline, it’s almost impossible to plan a measured, realistic approach to electrification.  

Electrification Works Best as Part of a Modular Plan 

Rather than treating electrification as a single large project, many owners are better served by a strategic approach, sequencing improvements over time. 

That could mean: 

Phase 1: Optimize Existing Systems 

Before replacing major equipment, many buildings can reduce emissions through: 

  • controls upgrades 
  • steam balancing 
  • ventilation improvements 
  • lighting retrofits 
  • operational tuning 
  • envelope improvements 

These measures often lower emissions while improving efficiency and reducing operating costs. 

Phase 2: Partial Electrification 

Next, owners may target systems that are easier to convert, such as: 

  • domestic hot water systems 
  • cooling equipment 
  • supplemental heating zones 
  • common area HVAC 

These projects can create measurable carbon reductions without requiring a full building overhaul. 

Phase 3: Major System Transition 

Larger electrification projects, such as central heating conversion or apartment-level HVAC replacement, can then be timed with capital cycles, utility readiness, and better future technology. This is the core value of Strategic Decarbonization Planning: making the right move at the right time. 

The Costliest Mistake Is Forcing the Wrong Project Too Early 

Some buildings hear “electrification” and assume they need to start with the most aggressive project possible. But moving too quickly can create expensive, avoidable problems.  

Owners may spend money on design work before a clear path has been established, trigger infrastructure upgrades before they are actually needed, or disrupt tenants for a project that does not yet deliver the right return. In some cases, the building may even take on higher operating costs while creating stranded equipment—assets that still had useful life remaining but are retired before their time. 

A building that replaced boilers five years ago, for example, may not need to scrap that investment immediately. With a thoughtful SDP, ownership may be able to maximize the life of those assets while planning a future transition aligned with later LL97 thresholds. 

In many cases, timing is just as important as technology. 

LL97 Readiness Is About Your Economics, Not Just Emissions 

The strongest decarbonization plans balance three realities: 

  • Carbon compliance 
  • Capital planning 
  • Operational economics 

That means looking at the full financial and operational picture, not just the carbon outcome. A strong plan should consider whether a project pays back over a reasonable period, how it may reduce future penalties, which incentives can offset upfront costs, and how changes in utility usage could affect operating expenses. It should also account for reserve funding needs, tenant comfort, and the day-to-day operational impact of the work. 

Buildings that only chase carbon reductions without evaluating economics often create new problems while solving one. Buildings that evaluate both can make durable progress. 

Why Early Planning Creates More Options 

Owners who start now typically have more flexibility than those who wait until deadlines are close. Early planning allows time to: 

  • compare multiple project pathways 
  • coordinate with other capital work 
  • pursue rebates and incentives 
  • budget reserves or financing 
  • avoid rushed contractor pricing 
  • reassess technology as markets evolve 

An SDP is not static. It should be reviewed and updated over time as regulations, costs, and equipment options change. 

The Smarter Question Is Not “Should We Electrify?” 

The question is: Where does electrification fit into our larger roadmap? 

For some buildings, it is the immediate next step. For others, it is a five-year milestone. For others still, it is one tool among many. 

The owners who will navigate LL97 most successfully are not the ones chasing buzzwords. They are the ones building thoughtful, phased strategies rooted in the realities of their property. 

That is what Strategic Decarbonization Planning delivers. 

Final Thoughts 

Electrification can be powerful. But it works best when it is part of a plan and not a reaction. For owners facing LL97, the goal should not be to electrify at all costs. The goal should be to reduce emissions intelligently, protect asset value, and move forward with confidence.

Strategic Decarbonization Planning: Video Series

Deep decarbonization doesn’t happen all at once – it happens in the right sequence, with the right information, and a clear financial rationale. This three-part video series breaks down the Strategic Decarbonization Planning (SDP) process into its essential steps, showing how thorough assessment, intentional design, and a compelling business case work together to move buildings from ambition to action. Whether you’re just beginning to explore decarbonization or ready to accelerate your efforts, these videos offer a practical framework, supported by real-world projects, to move forward with confidence.

The SDP approach is grounded in three key steps:

  • Examine Current Conditions
  • Design Resource Efficient Solutions
  • Build the Business Case

A clear picture of your building’s current conditions is where every great decarbonization plan begins. The first step of the SDP process involves rigorous assessment of your building’s current conditions to reveal where energy is being used, where it’s being lost, and where interventions will have the greatest impact. Watch the video below to see a project from NYSERDA’s Empire Building Challenge, illustrating how comprehensive assessments unlock smarter, more strategic retrofit pathways.

The second step of the SDP process focuses on designing resource-efficient solutions that prioritize efficiency before electrification. Known as Resource Efficient Decarbonization (RED), this step prioritizes reducing energy consumption, cutting emissions, and recovering waste heat as much as possible to create a strong foundation for cost-effective electrification down the line. See how this approach shaped the retrofit strategy at a Bronx affordable housing cooperative below.

Step three of the SDP process transforms a decarbonization roadmap into a financial case that moves decision-makers to act. By holistically quantifying costs, savings, incentives, and avoided risks, a well-built business case gives decision-makers the clarity to choose the right pathway with confidence. Watch the video below to see how two large multifamily buildings are creating business cases that drive performance and long-term asset value.

Energy Recovery Mapping Tool

Recovering waste heat in buildings is a key strategy for improving energy efficiency and reducing remissions. Many building systems, such as cooling equipment, wastewater, and ventilation reject heat that has the potential to be captured and reused in everyday building operations. Mapping these opportunities at the outset ensures that retrofit plans are both efficient, and cost-effective. 

This downloadable energy mapping tool builds on our Energy Sources and Sinks Inventory Tool to help project teams identify and quantify recoverable heat through analysis of building-specific data. While it can be applied to any building type, it was created with large commercial and multifamily properties in mind and is geared toward building owners’ staff and consultants leading decarbonization efforts. See instructions below and download the tool to start evaluating your building’s energy recovery potential.

Purpose: Compare building-specific data for source(s) and sink(s) to estimate potential energy recovery. Default assumptions and data are included to streamline the process. The following common use cases are included in the tool:

  1. Capturing heat rejected by the cooling system to improve space heating system performance.
  2. Capturing heat rejected by the cooling system to improve domestic hot water (DHW) heating system performance.
  3. Capturing heat from wastewater to improve domestic hot water (DHW) heating system performance.
  4. Capturing energy from exhaust air to temperature outside ventilation air.

Phase: This spreadsheet tool is intended to supplement other engineering and financial analysis tools during the Planning phase. Additionally, it is recommended the team review the spreadsheet tool during the Pre-Planning phase and identify data collection needs. This is critical, because if data isn’t already being collected the metering will need to be initiated and data collected over a range of operating conditions (e.g. throughout the winter). 

Inputs: Input requirements are dependent on the use case: 

Use cases 1 & 2: Short-interval (e.g., hourly) data for source(s) and sink(s) relevant to the energy recovery use case(s) to be evaluated. The data is typically collected using data trending through the building automation system. Additional metering (e.g., thermal energy “BTU” meters) may need to be installed. Data collected should also be reviewed for accuracy and completeness and normalized for factors such as outside air temperature. If data cannot be collected from the building, explore leveraging an energy model for estimates. 

Use case 3: Attributes about the building’s occupancy, domestic hot water usage, and wastewater.

Use case 4: Attributes about the building’s air distribution system.

Outputs: Annual load and recoverable heat per use case. Data collection initiated to support future heat mapping.

This spreadsheet is not a comprehensive design tool but can generate inputs for energy and financial analyses used in investment decision making.

Energy Sources and Sinks Inventory Tool

Waste heat isn’t waste—it’s an untapped resource. Recovering energy that would otherwise be rejected from a building can both reduce greenhouse gas emissions and improve the economics of decarbonization projects. This applies across a range of uses, including space heating, heating ventilation air, and domestic water. To maximize the impact of decarbonization retrofits, it’s essential to consider energy recovery during the planning process. By identifying and thoughtfully integrating heat recovery solutions early on, project teams can reduce energy demand, improve system efficiency, and enhance the overall cost-effectiveness of building upgrades. 

This downloadable spreadsheet tool is designed to help project teams identify and document potential energy recovery opportunities during the pre-planning phase, ensuring these opportunities are captured for analysis later in the retrofit planning process. It is intended to support building owners and their staff, such as facility managers, energy managers, engineers, and consultants advancing decarbonization planning in large commercial and multifamily properties. While this spreadsheet tool was developed with existing, large commercial and multifamily properties in mind, it can be utilized for any building type.

The tool uses targeted information from a building’s existing systems as its inputs, capturing the current conditions that shape retrofit opportunities. The resulting output provides clear documentation of energy recovery and renewable heat sources that create a foundation for analysis in later phases. Download the tool below to unlock your building’s energy recovery potential.
