Nerva Energy Drives Sustainable Smart Building Conversions in Ontario

December 12, 2024

Nerva Energy Group Inc., a company based in Hamilton, Ontario, has embarked on a groundbreaking smart building conversion project aimed at enhancing energy efficiency and promoting sustainability. The ambitious initiative involves transforming 85 multi-residential buildings across southwestern Ontario, covering a total area of 13.3 million square feet. The primary goal is to optimize energy usage and significantly reduce greenhouse gas emissions, setting an exemplary standard for future building projects. Through meticulous planning and implementation, Nerva’s project not only meets but surpasses the owner’s initial expectations, achieving remarkable results in energy conservation and financial returns.

Mechanical Optimization for Energy Efficiency

A fundamental aspect of the project involves substantial mechanical optimization of critical equipment such as boilers, chillers, cooling towers, and air delivery systems. By identifying operational inefficiencies and optimizing the performance of existing systems, Nerva has managed to achieve significant energy savings. One key discovery during the project’s implementation was that a small fraction of tenants accounted for a disproportionate share of heating and cooling consumption. This was due to windows and doors being left open throughout the year, causing unnecessary energy waste.

To address this issue, smart sensors were installed to monitor and notify building management about such inefficiencies, enabling prompt corrective actions. This proactive approach has led to more efficient energy use and has helped to maintain optimal indoor climates. The project is expected to deliver a 16% return on investment, primarily driven by reductions in utility bills, far exceeding the initially anticipated 12% return. Central to the project’s success is the ability to measure, monitor, and optimize energy consumption in real-time, ensuring sustained improvements in energy efficiency.

Achievements in Reducing Greenhouse Gas Emissions

Nerva’s initiative has already demonstrated impressive outcomes in reducing energy consumption and greenhouse gas emissions. The project has decreased electricity usage by 3.1 kWh and natural gas consumption by 1.3 million cubic meters, equating to a 36% reduction in greenhouse gas emissions. These achievements not only contribute to environmental conservation but also enhance the buildings’ net asset values by approximately $33 million. The model set forth by Nerva is a testament to the potential for substantial improvements in energy efficiency through targeted mechanical optimization and data-driven decision-making.

Earning numerous accolades, including the prestigious energy project of the year in Canada from the Association of Energy Engineers, and being listed among Clean50’s top sustainability projects, Nerva’s initiative stands as a pioneering example in the field of smart building conversions. The approach taken by Nerva demonstrates that systematic monitoring and optimization can lead to significant reductions in energy waste while generating positive financial outcomes for building owners.

Exploring Renewable Energy Solutions

As part of the project’s second phase, Nerva is conducting thorough evaluations to determine which equipment should be replaced to achieve optimal operational efficiency. The focus is on transitioning away from fossil fuels by exploring cost-effective renewable energy solutions. Among the options being considered are ground source heat pump systems, which have the potential to meet 90 to 95% of the heating needs in three upcoming buildings. These systems leverage geothermal energy, providing a sustainable and efficient heating solution that aligns with the project’s environmental goals.

Additionally, Nerva is investigating the integration of solar photovoltaic systems on rooftops and above parking garages to further enhance energy efficiency. This combination of renewable energy sources aims to not only reduce dependency on conventional energy supplies but also decrease operational costs over the long term. Data collected from the 85-building project indicates that up to 50% of energy used in multi-residential buildings is wasted. Through strategic optimization and the implementation of renewable energy technologies, this waste can be drastically minimized.

The Role of IoT in Smart Building Performance

The ability to quickly access real-time building condition data via Internet of Things (IoT) technologies has been instrumental in driving energy efficiencies in Nerva’s project. IoT-enabled devices create energy performance dashboards that allow continuous monitoring and prompt identification of inefficiencies. This transparency and responsiveness are crucial for maintaining the improvements achieved through initial optimizations and ensuring long-term energy conservation.

Rather than taking a full conversion or fuel-switching approach from the start, Nerva emphasizes the importance of optimizing existing equipment. This method has proven to be both cost-effective and successful in delivering significant energy and cost savings. By establishing a real-time connection to building performance data, Nerva can swiftly identify areas for improvement and implement solutions that lead to immediate and measurable benefits.

A Scalable Model for Future Projects

Nerva Energy Group Inc., headquartered in Hamilton, Ontario, has initiated an innovative project to convert buildings into smart, energy-efficient structures, focusing on sustainability. This extensive endeavor targets 85 multi-residential buildings throughout southwestern Ontario, encompassing an impressive 13.3 million square feet altogether. The key objective is to optimize the use of energy and substantially diminish greenhouse gas emissions, setting a high benchmark for future building endeavors.

Through detailed planning and execution, Nerva Energy not only meets but exceeds the initial expectations of building owners. The results are extraordinary in terms of energy conservation and financial gains. The initiative is more than just a retrofit; it’s a comprehensive overhaul designed to maximize efficiency and sustainability. Each building undergoes a thorough evaluation to ensure the most effective strategies are implemented. As a result, Nerva’s work serves as a stellar example of how smart technology and meticulous project management can deliver significant dividends, both environmentally and economically.
