Commissioning and Optimization of Energy Systems

Optimization of energy systems is accomplished by measuring and documenting existing performance and identifying potential improvements available through low cost control system and operational changes.

Commissioning of energy systems is a systematic process of evaluating all pieces of equipment to ensure that they are working according to specifications. This includes measuring temperatures and flow rates from all HVAC devices and calibrating all sensors to a known standard and reviewing the sequence of operations to verify that the controls are providing the correct interaction between equipment.

Technical Energy Audits and Analysis

Energy audits identify building and system components and characterize energy use through utility billing analysis and equipment and system performance analysis. Audits may entail measurements, monitoring or simulation and modeling. Typically audits will identify specific energy efficiency measures but may simply provide a benchmark for energy management activities.

Technical analysis generally refers to detailed cost benefit analysis of potential capital improvement projects either aimed at improving energy efficiency or where efficiency improvements may be available through modifications to capital projects undertaken for other reasons.

Typical applications and experience:

• Commercial and institutional buildings

• Central heating and cooling plants

• Industrial facilities and processes

• Ski Resorts

Industrial Systems Analysis

Detailed analysis of industrial systems is conducted in order to characterize current performance and identify opportunities for performance and efficiency improvement. Analysis typically includes detailed measurements and short term monitoring of power, flows, temperatures, pressures, etc.

• Fan systems – blowers, bag houses, induced draft and forced draft systems, exhaust, material handling, …

• Pump systems – process pumping, cooling and heating systems, de-watering, …

• Lighting

• Refrigeration – cold storage, process cooling, ammonia systems, ice builders, etc.

• Process Heating – steam systems, furnaces, boilers, autoclaves and heat treatment, …

• Motors and motor driven systems – conveyors, material handling, …

• Compressed air systems

New Construction Design Assistance

The greatest opportunities for incorporating energy efficiency and sustainability into a building come in the design phase. We provide building simulation and design assistance to Owners and design teams to support their efforts in obtaining the maximum possibly efficiency within each project’s constraints.

LEED (Leadership in Energy and Environmental Design) Green Building Rating System® is a voluntary, consensus-based national standard for developing high-performance, sustainable buildings. Developed by United States Green Building Council’s (USGBC) members, representing every sector of the building industry, LEED provides a complete framework for assessing building performance and meeting sustainability goals. Based on well-founded scientific standards, LEED emphasizes state of the art strategies for sustainable site development, water savings, energy efficiency, materials selection and indoor environmental quality. LEED recognizes achievements and promotes expertise in green building through a comprehensive system offering project certification, professional accreditation, training and practical resources.

High Performance Buildings are buildings with energy, economic, and environmental performance that is substantially better than standard practice. They are energy efficient, so they save money and natural resources. They are healthy places to live and work for their occupants and have relatively low impact on the environment. All this is achieved through a process called whole-building design.

Whole-building design takes into consideration the building structure and systems as a whole and examines how these systems work best together to save energy and reduce environmental impact.

Quality Assurance and M&V for Performance Contracting

Measurement and verification of energy efficiency projects includes formal measurement and verification (M&V) for performance contracting and less formal verification of savings and functional performance of individual or groups of efficiency retrofits.

We can apply the International Performance Measurement and Verification Protocol (IPMVP) when called for and use related Guidelines such as ASHRAE Guideline 14 – Measurement of Energy and Demand Savings.
