ENERGY EFFICIENCY AUDITING
H&H has qualified Certified Energy Managers (CEMs), and Professional Engineers (PEs) that are able to perform comprehensive energy audits in all sectors including residential, commercial, agricultural, and industrial. H&H will provide a professional report that will provide a detailed explanation of all recommended energy conservation measures (ECMs) and will rank them by the highest priority. A detailed financial analysis of all measures including a simple payback, return on investment, net present value and annual cash flow analysis will be performed.
H&H is able to look at all sources of energy use, including but not limited to:
- Space heating
- Space cooling
- Heat recovery
- Building envelope
- Water heating
- Kitchen exhaust hoods
DEMAND SIDE MANAGEMENT
Demand is the instantaneous use of electric power. Energy demand as seen by the utility company varies throughout the day, with the peak typically occurring during day hours when buildings are occupied and equipment such as air conditioners are running. It costs the utility more to produce power during on-peak hours of high energy demand. Utilities pass on this cost by charging customers (typically commercial and industrial customers rate payers) a demand charge based on the facility’s peak demand (kW) for any 15 minute interval of the billing cycle.
Demand side management is a modification of energy demand with a goal to lower the maximum peak demand of the facility. DSM does not necessarily decrease energy consumption, but by lowering the demand charge of the facility, a facility can lower their electric bill. The demand charge can commonly account for 30+% of a utility bill.
UTILITY RATE ANALYSIS
H&H has an in depth knowledge of utility rate structures and can provide a detailed analysis of all your utility bills (electric, gas, water, and others). Analyzing your utility bills can help you understand how much energy you’re using and the anomalies. A facility’s utility bills can often tell a lot about its inefficiencies without a detailed on-site audit.
H&H can also provide a total BTU (energy) value for your facility and benchmark it to other similar buildings through what’s called an energy utilization index (EUI). This can show you where you fall in relationship to similar types of buildings and will show you how efficiently or inefficiently your facility uses energy. A high ranking in terms of BTU/sqft means your facility can benefit from energy efficiency and conservation practices or retro-commissioning.
