Illing Middle School was built in 1960 and last renovated in 2006. The building consists of 134,796 square feet that includes 2 gymnasiums, 40 general education classrooms, 3 art rooms, 3 music rooms, 2 culinary rooms, 4 technology education rooms, a library/media center, and office space. In 2021, boilers were replaced and then in 2022 the replacement of cooling systems for 10 classrooms was completed. MPS maintains its HVAC systems to a high standard. Through its preventive maintenance program, regular analysis and record keeping of all air-handling units, their age, and condition, MPS adheres to planned replacement of HVAC systems and equipment that are reaching the end of their useful life cycle or are experiencing frequent costly repairs. The replacement of cooling systems at Illing Middle School was identified in MPS plan to maintain the overall air quality in the school to ensure a safe and healthy learning environment for students, staff and the community. The designs needed for this project includes the replacement of 7 rooftop cooling units (RTUs) at Illing Middle School. It also includes any necessary power upgrades and piping requirements to support the replacement units. Bidders shall include the cost of the HVAC system design including schematic drawings, diagrams, and technical manuals. Construction documents if needed and requested by MPS. Here are draft requirements for the design evaluation of the replacement rooftop HVAC equipment for Illing Middle School with a focus on sustainability, long-term energy use, and maintenance. Please note that the new equipment will utilize R-454B. 1. Building Design & Materials ● Rooftop Unit (RTU) Replacement: The new RTUs must optimize energy efficiency and integrate with the existing building envelope while adhering to load requirements. Preference should be given to high-efficiency models, such as those utilizing variable speed fans and heat recovery systems. ● Durable, Low Impact Materials: Materials selected for the project should be durable and have low environmental impact (e.g., recycled or locally sourced materials, low-VOC finishes). 2. Energy Efficiency & Long-Term Use ● Energy Recovery: Include energy recovery ventilators (ERVs) in the design to recapture waste heat for improved efficiency. ● Advanced Controls: Incorporate smart HVAC controls and sensors to optimize energy use, reduce operational costs, and provide real-time performance data.
