Pathways to achieving net-zero in buildings
Evaluating efficiency, electrification, generation and storage solutions for long-term sustainability
May 27, 2025 · Authored by Cora Klemme, Valerie Nubbe
As net-zero energy (NZE) and energy transition initiatives become increasingly prevalent – driven by policy requirements, decarbonization commitments and market demand – the built environment has emerged as a key focus area. The journey begins by identifying the right solutions for your facilities and operations, such as energy efficiency upgrades, electrification, on-site energy generation and storage. Complementary strategies like demand reduction and load shifting can further optimize performance, reduce upfront and operational costs and improve resiliency to grid disruptions. Taking a holistic approach to techno-economic assessment in scoping and bundling NZE initiatives can help bring them to fruition.
Efficiency and electrification
The first step in advancing net-zero goals is improving energy efficiency and electrifying on-site loads. By upgrading lighting, HVAC systems, weatherization and building controls, facility energy consumption can be significantly reduced. Electrifying end uses – such as space and water heating – reduces reliance on fossil fuels and enables clients to take advantage of an increasingly renewable power supply. Consider partnering with the right advisory firm to evaluate existing systems and utility consumption patterns to identify opportunities. At Baker Tilly, we use energy modeling tools and load profile analysis to help our clients understand the operational, emissions and cost impacts of energy conservation measures and fuel switching. These measures present the first line in reducing energy consumption and serve to prepare buildings for renewable energy integration. These upgrades often have the added benefit of improving occupant comfort, modernizing aging infrastructure and streamlining facility operations.
Increasing on-site generation
After reducing building load through efficiency and electrification, on-site energy generation is the next tool in the toolbox to achieve NZE. The remaining building demand can be met by powering facilities with low-carbon generating systems such as rooftop solar, or through the purchase of clean energy via the utility or a third-party agreement. Pairing these two strategies together helps to reduce overall cost by minimizing facility loads – and therefore the system size or residual energy purchases required to maintain those smaller loads. Baker Tilly supports our clients in identifying best-fit solutions for on-site installations and energy suppliers, including cost-benefit analysis, regulatory analysis and design support such as siting and sizing. Our data-driven approach empowers clients to make informed decisions about investing in energy production, advancing NZE targets and boosting on-site capabilities.
