Because City Hall was renovated to the LEED certification level in 2005-06 and Centennial Commons is a new facility that, while not LEED certified, was built with energy efficiency in mind, only modified audits would be necessary. Energy audits of City facilities would involve not only assessing the energy being used by these facilities now, but would provide recommendations on how to upgrade the facilities to be more energy efficient. Energy Audit Basics The objective of an energy audit is to identify and develop modifications that will reduce the energy use and cost of operating a building. The energy audit and master plan process includes the following steps: 1. Collect and analyze historical energy use (utility bills by meter, by building) 2. Conduct a facility audit-a study of the building and its operational characteristics. This is broken down into two on-site evaluations: a) A room by room analysis of lighting, fixtures, control technology, wall type/insulation, roof composite, windows (building envelope) and appliances. Hot water, laundry and food preparation areas will also be evaluated. Light levels are measured. b) The equipment audit, which is an examination by engineers of the building's HVAC system with the facility manager. This includes the boilers, air conditioning, pumps and control systems. 3. The energy auditors will conduct thorough interviews with the staff and management to determine the City's operational requirements including hours of operation, number of employees and citizens using the facility, space conditions, standard operating/non-use temperatures, night-time setbacks and any light level policies in place. (The audits can assist in developing space temperature settings and light level policies to achieve optimal spaces conditions and energy efficiency). 4. Develop an energy master plan that identifies the energy efficient measures (EEMs)-the potential modifications that will reduce energy use and cost. This will include an engineering and economic analysis of potential modifications. As the process unfolds economic targets for energy efficiency will be developed. Example: before decisions were made about what type of activities the City would submit to the federal government for the EECBG it briefly considered doing a selected energy audit on the Heman Park Community Center. While the building had several features that could be fixed (cleaned or repaired at low cost) immediately to save energy, any major retrofits to the building would never save enough energy/cost to warrant the costs of the retrofit. The Community Center costs the City about $12,000 per year in electricity per year. Even assuming gas usage were the same, the costs to retrofit this antiquated structure would far 7
