Commercial PACE Consulting

As one of the nation’s first and most experienced PACE project Technical Reviewers, CEI provides C-PACE consulting services to State and Local governments, lenders, and project owners in a variety of ways:

  • Performance of technical reviews for loan underwriting, for both State financing agencies and private lenders, to provide confidence that C-PACE projects meet stated financial objectives.
  • Advising State and Local governments on C-PACE program efficacy and the need for proper technical reviews.
  • Performing Owner’s Rep services for large C-PACE project owners, including commissioning review and M&V oversight.

Smart Grid/Microgrid Solutions

As one of only a few energy consulting firms that have experience in this relatively new arena, Celtic Energy has distinguished itself by overseeing one of this nation’s few operational Microgrid projects for the FDA, and serves as Third-Party Consultant to Connecticut’s first Microgrid project with the City of Stamford. Some of the specific ways we can help clients are:

  • CEI can help with the conceptual design of a Microgrid, incorporating both Combined Heat and Power (CHP) and alternative energy sources.
  • We serve as a project facilitator to support you throughout the Microgrid development process.
  • We have partnered with several experienced engineering firms with significant design experience in combined heat and power installations and microgrids to support preparation of Microgrid PFAs.

Energy Audits, Models and Benchmarking

Energy Audits Modeling Services

Conducting energy audits is one of the simplest ways to take steps toward reducing energy consumption and costs. Celtic Energy conducts two different types of these walk-through evaluations of a facility:

  • Preliminary Audits – A cursory investigation aimed at helping to pre-qualify projects before proceeding to a more detailed evaluation. This type of audit is also executed by CEI when creating a Request for Proposals (RFP) in order to provide a scope of work to the ESCOs and ensure all companies are given the same information. Also known as ASHRAE Level I audits.
  • Investment Grade Audits – A detailed engineering document confirming the scope and savings of potential projects. This audit is much more specific than the Preliminary Audit, and will often lead to specific recommendations for Energy Conservation Measures or Operations & Maintenance Improvements. Also known as ASHRAE Level III audits. We also conduct Level II audits, which are more comprehensive than the preliminary but not fully investment grade to help owners better identify potential savings opportunities without the cost of a Level III audit.

Celtic Energy also offers energy modeling and benchmarking services for commercial, municipal, and school system clients. CEI routinely uses building energy performance simulations or “energy models” and has constructed models for buildings using both eQuest and Trane Trace software. CEI is an energy modeling Technical Services Provider for United Illuminating. CEI is using an eQuest energy model of a new residence hall at the University of New Haven to inform LEED Silver green building certification compliance, as well as to secure substantial Energy Conscious Blueprint program utility incentives.

As an Energy Star Partner we also evaluate facilities’ energy usage and provide reports ranking them among peer facilities nationwide, as well as recommending energy conservation measures to increase their ranking. Celtic also provides LEED certification to facilities.

Sustainability Projects

Businesses and organizations are becoming more concerned about the impact they are making on the environment, and how that impact will affect their operation from an economic and social standpoint. Building a sustainable operation requires a broad understanding of the various processes involved in mitigating environmental damage, including those not traditionally associated with energy usage. Meeting corporate or government mandated goals presents a formidable challenge to management teams, one that Celtic Energy is well-qualified to help achieve.

Celtic’s Sustainability Group provides a broad scope of services to help our clients work towards a sustainable future, including:

  • Training of both management teams and employees on Sustainability Issues.
  • Development of organizational Sustainability Plans.
  • Review of current processes impacting air quality, water quality and conservation, and energy usage.
  • Strategies for improving processes to meet goals and work towards net-zero energy facilities.

CHP/Resilience Strategies

Storms and other natural disasters have recently highlighted the poor resiliency of some energy supply systems and the negative impact of this on our society. New and re-engineered energy supply systems must be designed to be extremely resilient to ensure public safety and mitigate damage to local economies. Celtic Energy can provide in-depth reviews of proposed new or modified energy supplies for our clients to help ensure they maintain minimal downtimes in the event of a disaster. This service may be provided on a stand-alone basis or in conjunction with Microgrid development projects.

Chris Lotspeich, Director of Sustainability Services, is a national thought leader in this space, and regularly facilitates, moderates, and speaks on panels for Resilience conferences across the country.

Retro-Commissioning (RCx)

As your building ages and its occupants change, it is important to review your building’s control strategies and operating procedures. Malfunctioning and outdated control logic can cause a building’s management system (BMS) to use more energy and prevent it from operating at peak performance. Retro-commissioning (RCx) allows you to identify energy savings in existing commercial and industrial buildings by improving the BMS’s operation. CEI’s Retro-Commissioning programs helps get this process off to a smooth start and works with utilities who provides financial incentives and technical advice. CEI consultants have attended training for RCx work, and we are an RCx Technical Services Provider for Baltimore Gas & Electric and United Illuminating.

GHG/Carbon Reduction Plans

The goal of reducing both greenhouse gas (GHG) emissions and carbon footprints is an important part of an organization’s overall Sustainability Plan. Celtic Energy can establish for our clients an initial benchmark of both, so that future comparisons can be made once operational modifications are made. We also provide objective advice on steps to be taken to mitigate GHG and minimize carbon footprints on a stand-alone basis, or as part of a greater overall Sustainability Plan.



Energy Conscious Design Reviews

CEI helps clients greatly reduce total overall project costs by offering our ECDR Service.  We work with your architects and engineers to enhance the energy efficiency and sustainability of your new or renovated facility before and during construction.  Under this service, some of the key elements CEI will review for our clients are as follows:

  • Overall design, from an energy efficiency and sustainability standpoint
  • Building envelope design and materials
  • Energy models, as developed by your engineering contractor, or develop our own
  • Inclusion of alternative energy sources to offset utility costs
  • Possible microgrid development to ensure reliability and resilience
  • Mechanical equipment, to ensure the most efficiency is obtained
  • Building control systems
  • Lighting
  • Ways to minimize gas and water consumption

Performing an ECDR will allow for maximum energy and cost savings, while reducing greenhouse gas emissions and carbon footprint.  It will also provide a depth of service reliability and resiliency not previously considered.  The net result will be a project that delivers maximum value over the long term.
