Energy Audits & Feasibility Studies
CDH Energy has a long history of identifying and evaluating the potential of energy efficiency improvements at commercial, institutional, and industrial facilities. We complete traditional energy audits where we quantify energy uses in a facility, complete on-site audits of existing systems and equipment, and then identify potential ways to lower energy costs and improve system performance. We complete energy studies at ASHRAE Level I, II, or III depending on the client needs.
We are especially skilled at identifying and implementing low- and no-cost improvements, also known as retro-commissioning or controls tuning.
We also complete investment grade studies (Level III) to assess feasibility of capital intensive projects. We complete studies for a range of technologies including:
- Combined Heat and Power (CHP) and Microgrids
- Chiller Water Systems and Central Plants
- Geothermal Heat Pump Systems
Our energy assessments are often supported by short term monitoring of equipment power or runtime to help in quantifying the baseline for comparison. This helps provide a more accurate account of the savings potential from identified energy efficiency upgrades. We have substantial experience in understanding and applying complex utility bill tariffs when evaluating the impact of energy efficiency measures (EMs).
CDH studied the feasibility of various CHP approaches including gas turbines, internal combustion engines, fuel cells and microturbine for the college campus. We performed a detailed analysis of campus facility loads, thermal and electric outputs from the CHP system options and system efficiencies to determine cost savings.
