Portland Parks & Recreation, Energy Savings Performance Contract
Portland Parks & Recreation (PP&R) suffers from aged infrastructure (the average building age is over 64 years old), high-utility use (almost $5M in the last year), and significant deferred maintenance ($250M and growing). These conditions coupled with ambitious Climate Action Plan goals for the City render PP&R’s infrastructure ripe for investment in utility efficiency. Dakessian Consulting partnered with PP&R staff to develop an RFP to select an Energy Services Company to implement an Energy Savings Performance Contract to help PP&R achieve their goals. The RFP is based on City code and policies and leverages Dakessian Consulting's many years of experience to ensure that PP&R receives maximum value.
Port of Portland, Energy Savings Performance Contract
The Port of Portland's (Port) goal is to reduce greenhouse gas emissions by 15% below 1990 levels by the year 2020. A key strategy for achieving greenhouse gas reductions is to implement cost-effective energy efficiency projects throughout the Port. The Port solicited proposals from Energy Service Companies (ESCOs) to provide a comprehensive Energy Savings Performance Contract (ESPC). Dakessian Consulting provided project engineering services to oversee the Technical Energy Audit and Project Development Plans. The project's main focus was on LED lighting upgrades on the roadways and in the large parking lots around Portland International Airport. A wireless control system was included to ensure that the hours of operation could be tightly controlled, and to provide detailed data for verification of savings and ongoing operations.
Port of Portland, PDX Concessions Tenant Utility Metering System
Another strategy the Port is using is to sub-meter their concessions tenants' usage of gas and electricity. This allows the Port to better track usage that it controls, and to incentivize tenants to conserve energy. A thorough needs analysis was conducted followed by research into commercially available products. Plans and specifications were prepared for competitive bidding and Johnson Controls was selected to install the system. A particular challenge was developing an integration between the metering system and the Port's financial system that automates the generation of tenant utility invoices. The system went into full operation in 2016 and has been expanded several times to include new tenants.

Portland Bureau of Environmental Services, Renewable Natural Gas and Codigestion Economic Analysis
Portland Bureau of Environmental services (BES) is implementing a project to enhance revenues by upgrading its anaerobic digester with a treatment system so that the biogas can be sold as renewable natural gas. The project also incorporates codigestion of food waste to increase the production of biogas. During the planning phase, Dakessian Consulting provided a comprehensive economic analysis to determine the most attractive option and to identify factors requiring additional investigation. Metrics such as Net Present Value (NPV), Simple Payback, and Discounted Average Payback were analyzed. Sensitivity analysis was used to determine the key factors and parameters for project success.
