Arup undertook a campus-wide audit to improve sustainability and reduce energy costs

Arup was hired by Chevron Energy Solutions Company to perform a campus-wide, investment-grade energy audit for California Polytechnic University (Cal Poly), San Luis Obispo. The goal of the energy audit was to outline alternatives for meeting the requirements of the University Chancellor’s Executive Order mandating a 15% reduction in energy intensity and a 20% increase in renewable energy production. Additional project goals were to reduce water usage, improve water quality, lower greenhouse gas emissions, and extend the life of buildings that might otherwise have been demolished by improving their occupancy comfort levels.

Conducted in two phases, the Cal Poly, San Luis Obispo investment grade energy and water audits comprised 101 buildings dating from the 1920s to the present, including theatres, dormitories, sports stadiums, gyms, pools, health centres, offices, teaching buildings, research centres, laboratories, and a library. Arup provided utility data and drawings review, on-site reviews, and 3D model energy analyses. After reviewing each building, engineers provided a report with final recommendations, along with a detailed breakdown of costs and incentives to ensure that the client would see returns from investing in their implementation.

Bringing their vast knowledge of the built environment and the ability to model the buildings and identify potential conservation measures, the project team engineers were able to scale and manage such a large and diverse audit, deliver measure design sketches, and  provide recommendations in a tool that allowed the client and the end customer to select measures that not only met pre-defined financial criteria after detailed costing was completed, but several other important selection criteria as well.
