Jefferson County School District 509 Madras High School Technical Analysis Study

The Madras High School Technical Analysis Study (TAS) highlighted the critical role of HVAC optimization in enhancing energy efficiency across the 166,000-square-foot campus in Madras, Oregon. The study aimed to modernize outdated HVAC controls, improve ventilation strategies, and propose energy efficiency measures (EEMs) to align with cost-effectiveness criteria.

Challenges and Solutions

The existing system’s limitations, including reliance on an outdated automated logic interface and inconsistent ventilation rates, underscored the need for a direct digital control (DDC) system. Proposed solutions focused on implementing adjustable parameters and expanding demand-controlled ventilation to optimize energy use.

Collaborative Approach

Navigating diverse incentive requirements from the Energy Trust of Oregon (ETO) and Oregon Department of Energy (ODOE) was challenging and necessitated tailored energy analyses to meet stakeholder needs. Our team worked closely with ETO and ODOE engineers, designers, and control contractors to ensure that the optimized systems aligned with client goals.

Through comprehensive energy modeling and close collaboration, we uncovered scheduling inefficiencies in the existing building automation system, contributing to high energy costs. Implementing EEMs, including DDC optimization, resulted in significant savings including 5% on electricity, 30% on gas, and a reduction of 139 metric tons of CO₂ emissions, which is equivalent to powering 18 homes for a year.

This study exemplifies our commitment to creating sustainable, energy-efficient learning environments through innovative HVAC system improvements and targeted collaboration.
