LEED Coordination
Leadership in Energy and Environmental Design (LEED) is an internationally recognized green building certification system, providing third-party verification that a building was designed and built using strategies intended to improve performance in metrics such as energy savings, water efficiency, CO2 emissions reduction, improved indoor environmental quality, and stewardship of resources and sensitivity to their impacts.  In order to become LEED certified, a building must go through an application process with many pre-requisites and credits that must be documented.  This is a collaborative process between the entire design team and building owner.  With so many small pieces to a large project, it is often necessary to have one project team member that only focuses on the LEED documentation process.

Building Commissioning
Building commissioning is quality assurance for a building owner that they are getting exactly what they want and what they are paying for.  By integrating a commissioning agent with a building design team, the owner has someone involved every step of the way that is only concerned with the owner's interests.  The commissioning agent can be involved from the pre-design phase all the way through the occupancy phase and in many cases continue to be involved throughout the operation of the facility to verify systems continue to perform as they should.  Commissioning is a pre-requisite for any LEED project but can also be very valuable for any new building not attempting LEED certification.  Existing buildings will also benefit from retro commissioning by experiencing a reduction in energy costs and improved occupant comfort. 

Energy Modeling
Energy modeling can help optimize the building design and allow the design team to prioritize investments in the strategies that will have the greatest effect on the building’s energy use.  Energy Modeling can be used for many different purposes including:
Compare systems for Life Cycle Cost Analysis (LCCA)
Predict building energy use
Comply with LEED
Determine impact of energy related upgrades

Building Information Modeling and Clash Protection Services
Building Information Modeling (BIM) is a digital represenation of the facility that is not only important in the design phase, but also in the construction and post construction phases.  Since 2005, Crenshaw Consulting has been regularly providing engineering designs in Autocad as well as Building Information Modeling in Revit, Autocad 3D and Bentley BIM.  Most of our federal projects require both Building Information Modeling as well as Clash Protection. 

Industrial and Process Engineering
Industrial engineering is a branch of engineering which deals with the optimization of complex processes, systems or organizations. Industrial engineers work to eliminate waste of time, money, materials, man-hours, machine time, energy and other resources that do not generate value.
 
Process engineering focuses on the design, operation, control, and optimization of chemical, physical, and biological processes. Process engineering encompasses a vast range of industries, such as chemical, petrochemical, agriculture, mineral processing, advanced material, food, pharmaceutical, software development, and biotechnological industries. Process engineering involves translating the needs of the customer into production facilities that convert "raw materials" into value-added components that are transported to the next stage of the supply chain.
