Energy & Water Auditing

The US Department of Energy’s (DOE) Energy Information Agency (EIA) data shows that buildings account for 40% of the total energy consumption in the United States. With recent and ongoing advances in energy consuming equipment, sophisticated building automation controls and advanced energy data analytics technologies there is a significant opportunity to reduce the energy consumption in buildings and reduce their carbon footprint.

As recognized industry experts, Verdafero consults with large and small businesses to help reduce their energy usage and costs through energy efficiency. We have experience in a variety of building types such as:

  • Commercial office buildings
  • Public and private schools and school systems
  • University campuses
  • Local, State and Federal government facilities
  • Multi-family and mixed-use buildings
  • Sports stadiums and arenas
  • Water and wastewater treatment facilities

Verdafero can tailor services specifically to your needs, on projects ranging from one building to assessments and recommendations spanning across an entire portfolio.

Commercial Building Energy & Water Audit Services

Verdafero provides professional energy consulting services to identify energy saving opportunities and implement turnkey solutions to enable your buildings to run efficiently, with the environment in mind. Typical energy savings can range from 10% to 30% of the total energy consumption baseline.

Water audits entail analyzing all water using systems. They can reveal malfunctioning equipment as well as billing errors.

ASHRAE Energy Audits

Verdafero offers different levels of Energy Audits based on industry standard ASHRAE Level-I, II & II commercial building energy audit guidelines:

Preliminary Energy Use Analysis

This involves analysis of historic utility use and cost and development of the energy utilization index (EUI) of the building. Compare the building’s EUI to similar buildings to determine if further engineering study and analysis are likely to produce significant energy savings.

Level-I: Walk-Through Analysis

This assesses a building’s current energy cost and efficiency by analyzing energy bills and briefly surveying the building. Level-I analysis identifies low-cost/no-cost measures and capital improvements that merit further consideration, along with an initial estimate of costs and savings.

Level-II: Energy Survey and Analysis

This includes a more detailed building survey and energy analysis, including a breakdown of energy use in the building, a savings and cost analysis of all practical measures that meet the owner’s constraints, and a discussion of any effect on operation and maintenance procedures. It also lists potential capital-intensive improvements that require more thorough data collection and analysis, along with an initial judgment of potential costs and savings.

Level-III: Detailed Analysis of Capital-Intensive Modifications

This focuses on potential capital-intensive projects identified during Level-II and involves more detailed field data gathering and engineering analysis. It provides detailed project cost and savings information with a level of confidence high enough for major capital investment decisions.

Retrocommissioning (RCx) and Commissioning (Cx) Services

In order to make sure that your building runs at optimal levels, either as planned or as desired, Verdafero offers Commissioning (Cx) services for new buildings and Retrocommissioning (RCx) services for existing buildings.

Commissioning and Retrocommissioning are akin to fine tuning the facility for optimal performance. The results achieved are checked through a measurement and verification (M&V) process and the typical return on investment for retro-commissioning projects is around the 1-year mark according to a study conducted by Lawrence Berkeley National Laboratory (LBNL).
