The Service’s Recovery Act project list contains a total of 210 projects that will directly reduce the energy consumption of Service facilities.
Types of Renewable and Efficient Energy Technology Projects
Energy Efficiency/Green Buildings
Tier 1 – Energy Conservation Measures ($21,071,000, 69 projects)
Tier 2 – HVAC and Process Energy Reduction ($13,667,000, 60 projects)
Use of Renewable Energy Sources
Tier 3 – Renewable Energy ($103,906,000, 81 projects)
Renewable energy and energy efficiency projects implement life-cycle cost effective energy conservation measures, process energy reduction strategies, and water conservation technologies, and install renewable energy systems. These projects will address mandated energy and water reduction goals while reducing operational costs at Service field stations and facilities. The Service has segregated these projects into three tiers: Tier 1 - energy conservation measures; Tier 2A - heating, ventilation and air conditioning (HVAC) systems; Tier 2B - process energy reduction measures; Tier 3 - renewable energy systems.
Tier 1 energy efficiency/green building initiatives include projects that will: retrofit/replace lights and install energy-efficient lighting systems (T-8 lamps and electronic ballasts); increase insulation; install programmable thermostats; weatherize; replace windows; and replace appliances with ENERGY STAR® appliances and energy efficient freezers. Projects may include conducting energy audits, sub-metering of facilities, and installation of electric meters. Water conservation practices in buildings and landscaping are also included in the Tier 1 category such as installing: low-flow faucets, showerheads, and fixtures; low-flush toilets and waterless urinals; systems for gray water reclamation and recycling; rain gardens; irrigation control systems; water retention or rainwater catchment basins; and xeriscaping (i.e., landscaping in ways that reduce or eliminate the need for supplemental irrigation). Xeriscaping is promoted in areas that do not have easily accessible supplies of fresh water.
Tier 2 energy efficiency/green building initiatives reduce more energy and are separated into two subgroups:
• Tier 2A – Heating, ventilation and air conditioning (HVAC) systems. Tier 2A energy efficiency projects include retrofitting energy-inefficient HVAC systems and controls, or installing new or replacement ENERGY STAR® HVAC systems and water heaters.
• Tier 2B – Process energy reduction measures. Tier 2B energy efficiency projects include replacing inefficient electric panels, pumps, motors, and drives; and rehabilitation of energy-intensive systems, predominantly at National Fish Hatcheries (e.g., U/V disinfection).
Tier 3 projects maximize use of renewable energy. Renewable projects produce electrical energy and thermal energy, which are counted differently toward meeting mandated renewable energy reduction goals. Electrical energy renewable projects include installation of solar photovoltaic (PV) power arrays, wind energy systems such as small propeller-type or vertical helix-type wind turbines, and microhydroturbines at National Fish Hatcheries. Thermal renewable energy projects include installation or repair of solar hot water systems, and installation of geothermal (ground-source) heat pumps. These projects will be designed to minimize the Service’s carbon footprint and may result in zero-energy buildings.
