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
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.

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.
