Developing energy efficiency solutions requires a detailed understanding of how and when a building, or process, consumes energy. The first priority in any efficiency study is to identify and remove the inefficiencies in the system(s). Once the waste is dealt with, then the focus can shift to the identification and redesign of low performance equipment and processes. An effective energy strategy typically involves a high-level system review, a detailed equipment assessment, and a representative energy model.
Energy screening audits are high-level assessments of the systems and processes in a facility. The goal of the audit is to identifying non-operational waste and cost effective energy conservation measures (ECMs). A typical screening audit starts with a review of the historical energy consumption data, and the creation of a benchmark for comparison against industry standards. With an understanding of the energy consumption trends and operational needs of a building, or process, Equilibrium can develop the preliminary list of energy savings opportunities.
Feasibility studies are a focused review of one or more systems within a building or process. The systems that merit further analyses are studied using direct data collection (i.e. data logging), which is then used to create a detailed model of how the process consumes energy. Once complete, the energy model allows the assessment team to analyze how the proposed changes will affect the annual energy consumption patterns, and provides a detailed life cycle cost analysis of the investment. The final result is an accurate implementation strategy that can be used by management to make decisions.
Energy models are mathematical representations of processes and systems within a building. The purpose of an energy model is to create an accurate view of how and when energy is consumed within a facility. Models can be applied broadly across the entire building, or focused upon a single piece of equipment. Equilibrium uses information collected from on-site studies, or engineering drawings, to develop and refine the model, and then applies cost data to the conservation measures being studied. Modelling can be applied to the preliminary design of new buildings, or to existing systems and processes. The end result is a better understanding of how a change in process, or investment in energy conservation, will affect the bottom line.
Renewable energy systems collect and use the various forms of the sun’s energy to do work in buildings and processes. The result is a reduction in fossil fuel consumption and ultimately the overall emissions related to the combustion of fuel, or generation of electricity. As most renewable technologies still demand a higher price point than existing systems, they are best implemented as part of a new design, or after the low cost energy conservation measures have been implemented. Equilibrium works directly with our clients to identify, assess and design renewable energy systems (solar, wind, biomass and geothermal) that fit the process with careful consideration for the operating budget.
