VWI’s approach for energy and water master planning is to define long term goals and develop a road map to meet energy, water, and renewable energy mandates. These objectives are addressed through analysis and planning of energy conservation measures, energy retrofits, capital improvement projects, and renewable energy projects.
In a recent project, a primary care clinic was experiencing humidity and condensation problems. Our team identified that negative building pressurization and the associated exhaust fans were not following the AHU shutdown schedule resulting in insufficient airflow. Additionally, some terminal boxes lost communications with the control systems and air sensors were out of calibration leading to a host of issues. Our engineers conducted troubleshooting and took the following action: removed the AHU shutdown schedule, reset and activated the boxes to maintain the required airflow, and increased the setpoint of supply air temperature. After the improvements, the relative humidity in the space returned to a comfortable level and condensation ceased.
In another recent project, the chilled water system in a community hospital was experiencing supply temperature regulation issues that the maintenance staff was unable to remedy. Our engineers conducted a through investigation, including analyzing the chiller design application data, pump curve, and chilled water system sequence of operation. They performed a series of field tests to identify the root cause. After crafting a temporary solution, our team worked to devise a long term solution to re-balance the chilled water loop.
Whether it’s constructing Energy and Water Master Planning for a large building portfolio to identify viable capital investments, retro-commissioning services to reduce overall energy consumption, or improving facility operations for long-term reliability and occupant comfort, our team works with our clients to find long-term solutions for increased savings and efficiencies. We are well versed with new mandates and requirements for renewable energy benchmarks, lifecycle processes to track energy and water savings, and common re-commissioning or retro-commissioning measures. We employ systematic and holistic approach to ensure a building meets its Current Facility Requirements, improves occupant comfort, and reduces energy use by optimizing facility operations and maintenance.
