Computational Fluid Dynamics (CFD) is a highly advanced technique used to simulate fluid flows, and its importance is hard to overstate in modern industry. By using CFD, engineers can accurately predict fluid dynamics, such as pressure, temperature, velocity, and turbulence in complex systems or processes that would be impossible to study through traditional experimentation.  CFD simulation services are an indispensable tool across a wide range of industries. These services provide a detailed understanding of fluid flows and thermal characteristics of products, processes, and systems, which can significantly benefit a company's bottom line. Loring has in-house expertise on the subject and has completed dozens of models for an array of project types.  Optimize HVAC System Design  CFD can be used to design and optimize heating, ventilation, and air conditioning (HVAC) systems. By simulating the airflow in buildings, Loring can determine the most effective placement of ducts, diffusers, and air handlers to ensure proper air distribution and minimize energy consumption. Specific use cases include airflow temperature and humidity prediction as a requirement for high-value artifacts or artwork in museums.  In a unique gallery space featuring a large double-height room, Loring’s contractual obligation to provide conditioned air to a specific area where valuable artwork was located presented a challenging situation. The tolerances for temperature and humidity requirements were extremely tight, leaving little room for error. To ensure the HVAC system could meet these strict specifications, Loring created a CFD model to evaluate and identify what changes were necessary. By simulating the behavior of air within the space, the CFD model provided valuable insight that enabled the HVAC system to be optimized and meet the contractual requirements, ultimately safeguarding the valuable artwork while maintaining the comfort and safety of the staff and visitors. At Loring, we use the best technological tools to meet our clients’ diverse needs.  Simulation Findings of a Museum Space Natural Ventilation Design Schemes  Supporting Loring’s net-zero energy focus, CFD is used to design and optimize natural ventilation systems. By simulating the airflow through buildings, Loring can determine the most effective placement of openings, such as windows and vents, to ensure adequate ventilation and indoor air quality.   For a recent project, a college dormitory utilized a mechanical ventilation scheme that supplied ventilation to the corridors and utilized exhausts within each dorm room to distribute the outside air. Through a CFD simulation, Loring was able to identify deficiencies with the existing HVAC configuration. We identified a solution that incorporated natural ventilation that would have minimal impact on the operation of the building and the existing infrastructure. Our team members are committed to delivering the best solutions to complex challenges.  3D Models and CFD Images of a College Dormitory     Energy Efficiency Design Approach  CFD can be used to design and optimize building systems for energy efficiency. By simulating the airflow and heat transfer in buildings, engineers can evaluate the effectiveness of different energy-saving strategies, such as passive solar design, shading devices, and natural ventilation. CFD can also be used to optimize the sizing and placement of building insulation and evaluate the effectiveness of different types of glazing and window systems.  "CFD modeling has revolutionized the way we approach complex design challenges, enabling us to leverage our fluid mechanics and building systems expertise to deliver innovative solutions that meet the needs of our clients. By simulating the behavior of airflow in real-world scenarios, we are able to identify potential issues and optimize designs to achieve optimal performance and efficiency, ultimately driving better outcomes for our clients." Steven J. Kenah, PE, CEM, CFPS, LEED AP President  Gas Dispersion Modeling  The unnoticed dispersion of hazardous gases such as carbon monoxide can have life-threatening implications. CFD can be used to model the dispersion of gases in different environments, such as indoor and outdoor spaces. By simulating the movement of gases under different conditions, Loring can determine the most effective placement of gas detectors and design a system that provides maximum coverage. CFD can also be used to evaluate the effectiveness of ventilation systems and identify potential areas of gas accumulation.  HVAC System  Introducing our latest project: a state-of-the-art HVAC system designed for hydrogen fuel cell production – the first of its kind in Canada. Our team of expert engineers faced a complex challenge due to the large volume of air required to purge the room housing the equipment in the event of a gas leak. To ensure the safety of the occupants, Loring used a CFD model to identify areas where hydrogen gas would accumulate and recommended the placement of gas detection sensors. We also ran multiple simulations to optimize the location of supply and exhaust duct openings, as well as gas detection sensor locations. The result is a reliable HVAC system that meets the strict safety standards required for hydrogen facilities as per the Canadian Hydrogen Installation Code (CSA/BNQ 1784). We are here to provide even our most groundbreaking clients with the best solutions for their safety needs.   Conclusion  CFD can be a powerful tool for designing and optimizing fluid mechanics in a variety of use case applications. By simulating the airflow movements in buildings, Loring can identify potential problems, optimize system performance, and design more efficient and effective building systems. As always, we aim to leverage the right technologies to provide comprehensive solutions for our clients.

As the healthcare industry continues to evolve, so too must the facilities that provide care. With new technology and innovative approaches to patient care, healthcare providers are looking for ways to adapt their existing spaces to better meet the needs of their patients. One way that healthcare providers are doing this is by transforming unconventional buildings into healthcare spaces. In this blog post, we'll explore how MEP (mechanical, electrical, and plumbing) engineering consulting firms can support adaptive reuse of spaces for healthcare providers and how to make the most of these spaces. We will also provide examples of challenges and opportunities that these buildings present based on our clients' experiences.  The Challenges of Converting Unconventional Buildings into Healthcare Spaces  Converting an unconventional building into a healthcare space comes with its own set of challenges. Depending on the building's original purpose, there may be unique constraints that need to be addressed. For example, a former warehouse may not have the necessary infrastructure to support a healthcare facility's electrical and mechanical systems. Similarly, an office building may not have the appropriate ventilation and air quality control systems required for patient care.  Another challenge is ensuring that the space is compliant with regulatory standards. Healthcare facilities are subject to a variety of regulations and guidelines, from the Americans with Disabilities Act (ADA) to the Occupational Safety and Health (OSH) Act. MEP engineering consulting firms can help ensure that the space is compliant with all relevant regulations and guidelines, minimizing the risk of penalties or fines.  The Importance of MEP Engineering Consulting in Healthcare Facility Design  MEP engineering consulting firms play a critical role in the design of healthcare facilities. These firms have expertise in designing and optimizing the electrical, mechanical, and plumbing systems that are essential to a healthcare facility's operations. They can help healthcare providers identify the most effective and efficient ways to design and implement these systems, ensuring that the facility is equipped to provide the highest quality of care.  For example, MEP engineering consulting firms can help healthcare providers optimize their HVAC systems to ensure that the air quality and temperature control are adequate for patient care. They can also help design and install specialized electrical systems that support medical equipment and provide backup power in case of an outage. Finally, they can help design plumbing systems that meet the unique needs of healthcare facilities, such as the ability to handle large volumes of wastewater or medical waste.  Case in Point: Clearpoint Health Network Surgical Centre Clearpoint Health Network Surgical Centre, Toronto, ON Clearpoint Health Network is a surgical center in Toronto that provides a variety of surgical and diagnostic services. The center is located in a former office building that had been vacant for several years. The challenge for Clearpoint Health Network was to transform this space into a state-of-the-art healthcare facility that could provide the highest level of care to patients.  Loring Consulting Engineers was brought on to help design and implement the necessary infrastructure to support the facility's operation. This included optimizing the HVAC system to ensure adequate air quality and temperature control, designing specialized electrical systems to support medical equipment, and designing plumbing systems that could handle the large volumes of wastewater and medical waste generated by the facility.  One of the most significant challenges faced by Loring was designing an adequate ventilation system for the facility's operating rooms. Operating rooms require a high degree of air exchange to maintain sterile conditions and prevent the spread of infectious disease. Loring designed a custom ventilation system that ensured the required air exchange while also minimizing the amount of energy needed to operate the system.  The result of this collaboration among Clearpoint Health Network, Loring, and architect C&Partners is a state-of-the-art surgical center that meets all relevant regulatory standards and provides the highest level of care to patients. By leveraging Loring’s expertise, Clearpoint Health Network was able to transform an unconventional building into a healthcare space that met the unique needs of its patients and staff.  Case in Point: Mount Sinai  The Mount Sinai Doctors-Forest Hills Clinic, Queens, NY Loring was involved in the conversion of a bank and retail building into a multidisciplinary clinic in Queens, New York, for the Mount Sinai hospital system.   The building’s accessibility by subway and train made it well-suited for people in the community, including the large immigrant population in the area. Overall, the project represented a significant expansion of Mount Sinai's presence in Queens and helped to meet the needs of patients in the surrounding community.  The building had three different tenants, including a gym, a bank, and a retail unit, with a total of 25,000 square feet of space. The new outpatient clinic includes a number of exam rooms, nuclear cameras, x-ray rooms, and blood draw labs, among other facilities.  One of the biggest challenges that Loring faced during the conversion process was the need to heat and cool a large volume of space, given the building's floor-to-ceiling glass and high ceilings. Strategically though, these made for some really beautiful waiting rooms, which supported the patient experience at the clinic.   Additionally, the building's large beams made it difficult to install ductwork and other MEP utilities, and the electrical system had to be upgraded to accommodate the high voltage required for the x-ray equipment.  The exhaust system and carbon filtration for the hot lab also presented a challenge. Through investigation and studying the building, Loring was able to determine a path to safely channel exhaust out of the lab to the roof and at least 25 feet away from the outside air intakes to the air handling units, etc.  Despite the MEP challenges, this unique space allowed the team (Mount Sinai doctors, architects Mascioni and Behrmann, and Loring Consulting Engineers) to create a state-of-the-art clinic equipped with the latest technology and characterized by a visually appealing waiting area in a highly strategic location that would not have been possible otherwise. In summary, converting a building into a healthcare center presents a range of MEP challenges and opportunities that are unique to each space. To successfully navigate this process, Loring recommends that clients conduct a feasibility study before signing a lease to fully understand the challenges, costs, and opportunities associated with the conversion. By doing so, clients can make informed decisions and ensure that their team is adequately prepared to address any issues that may arise during the conversion process.  Authors Nigel Bastiampillai is a Principal in Loring’s Toronto office, Rahul Tikekar is a Principal in Loring’s New York office.  

The journey towards achieving a net-zero emissions building can seem daunting and fraught with obstacles. Existing building constraints, as well as resource and time limitations, can impede progress towards optimistic goals of becoming a net-zero organization by 2050, a commitment many entities have made. Consequently, it may be tempting to postpone efforts for another decade. However, with regulatory mandates being implemented in the United States, it is probable that the Canadian government will face mounting pressure to follow suit. Therefore, it is imperative to be well-informed and take incremental steps towards achieving net-zero emissions now, to ensure long-term sustainability and resilience. In addition to contributing to a sustainable future, adopting such measures can yield significant cost savings and enhance your organization's reputation. This article simplifies years of experience in supporting organizations to achieving net-zero emissions through building electrification in five steps. Electrification is a critical component of moving towards a net-zero building. A net-zero building is one that produces as much energy as it consumes over the course of a year. To achieve this, it is necessary to reduce the building's energy demand and ensure that the energy used comes from renewable sources. Electrification helps to achieve both of these goals. By replacing fossil fuel-powered heating and cooling systems with electric ones, building owners can reduce their reliance on non-renewable energy sources. By leveraging insights from multiple case studies of our clients, we have identified five steps you can take now to prepare for future changes and achieve net-zero emissions.  1. Conduct a Comprehensive Energy Audit To begin the process of building electrification, it’s important to have a good understanding of the current energy consumption of the building. Conducting a comprehensive energy audit will help identify areas of inefficiency and opportunities for improvement. This can help guide decisions about which electrification strategies will be most effective for the building.  At Loring, we have extensive experience conducting energy audits, having completed over 600 ASHRAE Level II and Level III audit projects in the last 10 years. Through this work, we have identified numerous opportunities and strategies for our clients to reduce energy consumption and achieve their sustainability goals.   Our comprehensive approach to energy audits, informed by lessons learned from previous projects, enables us to provide our clients with the best-in-class learning and experience in the industry. We pride ourselves on consistently delivering high-quality results that exceed our clients' expectations.  2. Install High-Efficiency HVAC Systems  Heating, ventilation, and air conditioning (HVAC) systems are a major source of energy consumption in the buildings. Replacing old, inefficient HVAC systems with new, high-efficiency alternatives can significantly reduce energy consumption and emissions. This can include heat pumps, which use electricity to extract heat from the air or ground, or geothermal systems, which use the constant temperature of the earth to heat and cool buildings. This was the case in our recent major capital project at the Michigan State Capitol.   Loring is currently developing a design package for a new transit agency headquarters building in Ontario, Canada. The building MEP systems will be an all-electric solution focusing on sustainability as the project is slated to achieve LEED Silver and Net-Zero Greenhouse Gas status. More to come on this exciting project.  3. Switch to Electric Appliances  Replacing gas-powered appliances with electric alternatives can significantly reduce a building's carbon footprint. This can include electric stoves, water heaters, and dryers. The use of electric vehicles for transportation can also help reduce emissions associated with commuting and transportation.   However, a switch to electric is not always straightforward and has to be planned for.   Loring Consulting Engineers worked with a major Canadian bank on their sustainability program at a national level. The scope of work involved evaluating which bank branches could utilize electric appliances for heating and cooling, taking into consideration power capacity at each site. This provided the bank vital information to plan for conversions in the next few years, as units reached  end-of-life status.   4. Install Rooftop Solar Panels:   Solar panels can be installed on the roof of a building to generate clean, renewable electricity. This can help reduce a building's dependence on grid electricity and provide cost savings over time. In some cases, excess energy generated by the solar panels can be sold back to the grid, providing additional revenue.  Loring has been working with several K-12 schools to comply with local energy laws by designing solar photovoltaic systems that elevate the design requirements above minimum building code requirements. Though these additional requirements could be achieved by either a green roof or a blue roof, these options presented challenges that outweighed the benefits. A green roof can be prone to additional maintenance, while a blue roof presents substantial design and construction costs. These factors, coupled with the benefit of the solar photovoltaic system, reduced the amount of power required from the electrical utility grid, and ultimately guided the roof design options towards the ideal solution. At another site, the solar photovoltaic system was coupled with battery storage and export capability to the utility grid. More to come on this existing project! 5. Using Building Automation Systems to Reduce Energy Consumption A building automation system (BAS) can play a crucial role in achieving net-zero emissions by reducing energy consumption in buildings. A BAS can control and optimize various mechanical systems in the building, such as HVAC and lighting, to operate more efficiently and use less energy. By implementing measures such as converting airside and waterside systems to variable volume, adding night setback and optimized start sequences, and integrating renewable energy sources such as solar panels, a BAS can significantly reduce a building's energy consumption and greenhouse gas emissions. This, in turn, helps move buildings towards net-zero emissions and supports the electrification of building systems to rely more on renewable energy sources.  Loring recently completed a full renovation of the BAS at the 120,000- square foot Toronto City Hall complex. This involved the replacement of the entire BAS across the facility, including the two towers, podium, and Nathan Phillips Square. As part of the upgrade, various mechanical systems were reviewed, and multiple energy conservation measures were implemented to reduce the energy consumption and greenhouse gas emissions of the facility.   These measures included converting airside and waterside systems to variable volume, as well as adding night setback and optimized start sequences.  By making these changes, Loring calculated potential savings of 730,000 kWh/year of electricity, 840,000 lbs/year of steam, 95 tons/year of GHG emissions, and $141,000/year of utility cost savings. Following the completion of the BAS upgrade, the electricity and steam consumption were evaluated, and the utility bills showed a 20% reduction in electricity consumption.  Conclusion  As more and more Canadian organizations commit to reducing their carbon footprints and achieving net-zero emissions status by 2050, they are becoming increasingly aware of obstacles impeding sustainability – obstacles that must be overcome if their goals are to be met. With its long history of incorporating sustainability and energy efficiency into its work, Loring stands ready to partner with these organizations to create options that are both forward-thinking and environmentally responsible.  Authors Nigel Bastiampillai is a Principal in Loring’s Toronto office.
