90 CommerCial ConstruCtion & renovation — January : February 2014 BUilDiNg reNovatioN CirCle No. 38 Step No. 4 – The fourth step is the current implementation phase. Here, all approved low-cost/no-cost, M&R;, ECMs and FIMs are being im- plemented via MSU's Infrastructure Planning and Facilities Maintenance Services department or through the capital project process managed by the Infrastructure Planning and Facilities Engineering, and Architec- tural Services department. Maintenance Services and Engineering, and Architectural Services are working together to collectively implement the approved fndings from the above-described process steps. From that point, MSU moved into the validation stage, where it will validate the fnal report in terms of those four steps. It has a separate team called Energy Systems Alterations and Improvements that guides us to low-cost/no-cost and M&R; items. Step No. 5 – The ffth step ensures that what MSU implemented is running effciently and that documentation is up to date. Currently, it is in the midst of developing a continuous commissioning mecha- nism to ensure it perpetuates these results into the future. CCR Part of what infuenced Michigan State University's choice of Anthony Hall was data that came out of the frst three steps of its fve-step study. It always had suspected that laboratory buildings use more energy and had a higher energy-use index, and the profling proved it. The ranking system also looked at the types of systems and opportunities available for energy savings, in addition to the building's historical energy-use patterns. Through its study and data mining, MSU discovered several energy savings strategies for Anthony Hall. The strategies include: • Installing variable-speed drives on cooling tower fans: savings of $5,000 annually for the building and another $2,000 annually for process towers • Installing air-fow monitoring and repairing economizer damper controls: savings of $73,000 annually • Implementing demand-ventilation control strategies in auditoriums: savings of $2,600 annually • Installing air-quality sensors in laboratories: savings of $128,000 annually • Installing heat-recovery unit in the exhaust air stream: savings of $4,000 annually • Converting multiple building reheat systems to variable-speed systems: savings for all reheat work, including insulation and a variable-air- volume conversion of $23,000 annually • Upgrading lighting and installing lighting controls: savings of $10,000 annually The energy to operate buildings across the United States costs about $200 billion annually. On average, 30 percent of this energy is wasted. MSU's work as a partner in the Better Buildings Challenge lets it track, manage and save energy on campus while sharing data with other Better Buildings partners. By sharing what it has learned with others, it's committed to reducing energy consumption across the country while saving energy and providing more comfort for faculty and staff across campus. DOE calls its work a great model for other campuses. Jason Vallance is the commissioning manager with Infrastructure Planning and Facilities at Michigan State University.
