General Approach

EnergyAuditLevels-300x243

An EDGE Energy audit presents every detail about the building and its components to the owner. Our suggestions detail the effective steps towards implementing a package of improvements to achieve the owner’s goals. These goals could include reducing energy consumption, improving comfort throughout a structure, improving indoor air-quality, eliminating health and safety hazards, or even carbon footprint reduction.

We pride ourselves on the thoroughness and accuracy of our reports, our extensive knowledge of building science and best practices, and the timeliness of our analysis and installations. Every completed job is post-tested (Quality Controlled) and results are reported back to the homeowner, utility companies, federal government (IRS, DOE), and/or state programs as required for rebates, grant funding, and/or tax incentives. We always take the extra step to provide accurate results and keep our customer’s best interest in mind every step of the way.

Primary Objectives of a Commercial Energy Audit:

CommercialEnergyAudit

  • The primary goal will be to target utility bill savings and improvement opportunities within the building structure or mechanical systems that have a high-rate of payback and any items which will net a return after a capital expense. The Energy audit shall target basic cost-effective measures for reducing the electrical/gas/water consumption of the building in common and private areas.
  • Suggested upgrades will have an estimated payback calculated by calculations of similar systems and industry standards, or by directly calculating the kWh or BTU reduction of the overall assumed schedule of improvements or specifically for a particular given measure or recommendation.
  • Include a review of renewable energy systems potential for Solar, Wind, Cogeneration, and Geo-thermal retrofits (implementation, cost, and ROI).
  • Condition monitoring of equipment
  • Site survey of Energy Consumption
  • Identification of Major energy utilization equipment
  • Identifies minor snags in the System
  • Assessment of energy saving measures
  • Evaluation of operational controls
  • Generate a scope of work and rough pricing estimate for some or all of the suggested improvements.

Typical Building Elements Investigated:

EDGE Energy will provide all labor and materials to complete the inspection of all significant building equipment and systems, and to prepare a detailed energy audit report which will be utilized by the client as the means to achieve the most cost effective energy efficient improvements.

  • UTILITY ANALYSIS:Utilities often up-charge for the “excess demand” which is to cover your very “worst” electrical minute. Figure out where this is, and why, so that you can reduce it and run those loads during off-hours.
    • At the initial contact with the building manager, request that copies of the previous three year utility bills and other pertinent energy usage information be assembled and available at the time of the inspection.
    • Review utility occupancy and usage history from available utility bills.
    • Determine base load, heating, and cooling loads (computer software).
    • Analyze Cost/Tariff utility rate structure(s). This will be determined and analyzed, but the facility may or may not be eligible – often requires legal department aid.
  • AIR-LEAKAGE and BUILDING ENVELOPE: Conduct a visual check for cracks, gaps, and leaks to determine sources of excessive energy loss and water consumption, drafty spaces, uncomfortable temperatures, and poor indoor air quality.
    • Conduct blower door tests where possible to measure the tightness of the building envelope and expose leaks in the building shell.
    • Conduct Infrared (IR) survey (as purchased) of walls and ceilings to pinpoint thermal boundary and air barrier defects and air flow.
    • Trace moisture and condensation problems, as applicable
  • INSULATION: visual inspection of different types used throughout the building.
    • Suggest retrofit procedures for un-insulated or poorly-insulated areas
    • The thermal barrier of the building should line up (in most instances) with the air-barrier (see item #1). Exterior walls, roofs, and main entrances and foyers all have specific types of problems and required insulation levels that will be addressed.
  • INDOOR AIR QUALITY
    • Moisture buildup and ambient moisture load analysis; suggest source control measures
    • Run ambient CO and natural gas leak tests
  • INDOOR AND OUTDOOR LIGHTING
    • Itemize building and unit lighting loads and determine cost-effectiveness of upgrades
    • Lamps, ballasts, day lighting, fixtures schedules prepared from blueprints for indoor and outdoor lighting and ROI calculated for upgrades and changes.
    • Check of the electrical/power distribution system; interior and site luminary systems and controls, including lighting power density
    • Behavioral usage evaluation of computers, copiers, printers, and indoor appliances
  • MECHANICAL SYSTEMS: Perform an inspection, survey and analysis of energy flows in the building with the objective of understanding the energy dynamics and to assess energy usage.
    • Heating Equipment: Gas Furnaces and Boilers
      • Mark areas identified as leaks during the audit and provide a photograph inventory.
      • Combustion Safety Testing: zone pressure tests, ambient CO, natural gas leak detection as required by BPI Multi-Family Audit Standards.
      • Heating and cooling systems and controls
    • Cooling Equipment: Cooling Towers and/or Outdoor Compressors
      • Inspect for upgrade or maintenance opportunities.
      • Catalog in-unit window AC units (100% inspection – 51 total units) and space heaters and factor into computer model
    • Duct work: Inspect HVAC duct work for sizing and balancing improvements.
      • Inspect ductwork for leakage sites, provide sealing suggestions.
      • Conduct duck leaking test, if applicable.
    • Elevators: check the operational characteristics of the elevator(s).
    • Ventilation: Bathroom fans, kitchen exhausts, building ventilation
      • Check these systems for operation and schedules to comply with building code.
    • Co-generation (CoGen) and Combined Heat & Power (CHP) Equipment: Electrical generators that also produce hot water or hot air from generator waste heat and exhaust.
      • Inspect for upgrade or maintenance opportunities.
    • Domestic Hot Water: Look for basic improvement opportunities
      • Explore advanced improvements for heat recovery, cogeneration, or solar thermal water heating.
      • Inspect the existing boiler and hot water storage tanks.
      • Suggest maintenance or replacement plan.
  • RENEWABLE ENERGY SURVEY(S) – Run an alternative energy study.
    • Analyze roof condition with visual inspection
    • Perform Solar thermal and Photo-voltaic (Solar PV) site analysis and sun orientation azimuth
    • Produce estimated installation costs, energy return, and ROI calculations.
    • Perform Geo-thermal well sizing and prelim budgetary estimate
  • ADVANCED ENERGY SYSTEMS
    • Investigate feasibility only – NO ENGINIEERING INCLUDED in this audit
    • Combined Heat and Power (CHP or CoGen)
    • Central Energy Management Systems (EMS)
    • Advanced Metering, Peak Demand response, Demand management and mitigating systems
  • PERFORMANCE – WORKSCOPE – ECM Module Analysis
    • Conduct detailed engineering analysis to support recommended capital-intensive modifications focusing on capital-intensive opportunities based upon a high degree of data collection.
