Energy consumption studies, energy audit, conservation recommendations and building systems design for new and retrofit systems

With limited natural resources, inflated energy costs, increasing air pollution and heightened awareness of climate change, energy conservation is an opportunity for building owners, campus and facility managers.

Because facility energy requirements vary based on design, use, location and orientation, it is critical to define and measure energy efficiency for buildings in order to improve energy performance and efficiency. At P2S, we know how to improve building energy efficiency in facilities. We do this by first leveraging our knowledge of existing systems, maintenance and operations and utility rate structures.

Second, we draw on our experience in working with emerging technologies and renewable energy sources. Finally, we identify the key factors critical to the success energy projects, including optimization for maximum annual energy efficiency, compatibility, reliability, and maintainability, as well as those that affect both the environment and the depletion of natural resources. We also help our clients offset capital costs required to execute these projects by understanding and leveraging all the various incentives available from state and federal programs.

P2S is also well-versed in the design and implementation of renewable energy technologies. We help our clients minimize the use of natural resources and limit the dependence on fossil fuels. This minimizes exposure from volatile and escalating energy costs while providing environmental benefits by reducing greenhouse gas emissions. In addition, these technologies reduce operating costs by minimizing future carbon emissions expenses and peak demand usage charges.

P2S building energy and systems design services include:

  • Energy Efficiency Master Planning
  • Renewable Energy Sources (photovoltaic, fuel cells, solar-heating, daylighting)
  • Economic Feasibility Studies
  • Energy and Carbon Reduction Audits
  • Energy Modeling
  • Energy Reduction
  • Commissioning
  • Energy Management Report & Metering
  • Alternative Energy Systems
  • Incentive & Rebates
  • Measurement & Verification (Actual Savings/Data Logging)
  • Thermography

Through the availability of many state and federal incentives for new and emerging technologies, these technologies continue to become more attractive and cost-effective solutions to achieving greater facility energy efficiency.


Computer simulation tools to optimize engineering solutions: Building Energy Modeling, Building Information Modeling, and Performance Modeling

We discovered that by incorporating performance analysis into our design workflow, the process stimulates collaborative thinking, multidisciplinary decision-making, creativity and innovation—all critical elements for successful engineering design.
Our modeling experience allows us to customize the analysis to fit project needs for building energy efficiency, carbon emissions, daylighting, thermal comfort, solar shading and penetration, glare, luminance and illumance (radiance), artificial lighting, internal loads and building envelope manipulation. Whether the task is to evaluate the energy performance of various design alternatives or perform a short circuit analysis on an electrical infrastructure system, P2S has the tools and experience to provide these simulations.

Energy modeling and simulation is the key to whole building design and optimizing building envelopes, lighting and HVAC systems. By using this technology on building systems design, it is possible to achieve dramatic energy reductions while ensuring good daylight levels and thermal comfort. P2S Engineering, a Long Beach, California consulting engineering company brings broad experience in the design, implementation and commissioning of real-world projects and provides the necessary background to better model building performance.

BIM (Building Information Modeling)

Why Building Information Modeling?

Building Information Modeling is an integrated process for collaboratively exploring a project’s key physical and functional characteristics digitally, before even breaking ground or beginning prototype production. BIM is characterized by the early development of information-rich, coordinated, 3D models that remain at the center of the workflow throughout a project’s lifecycle, from planning and design through construction and into operations. The use of BIM results in data-rich as-built models that contain a great amount of information for smarter building operations by the owner and facility manager. Building Information Modeling enables P2S to work collaboratively and communicate system design efficiently with the entire project team and helps prevent conflicts from occurring during and after design when the project goes into construction, saving valuable time and money.

Building Information Modeling + Integrated Project Delivery (IPD) = Coordinated Projects

With IPD and BIM evolving as the most common practice for project delivery, P2S recognizes that collaborative digital design is essential to a project’s success. Here at P2S, Integrated Project Delivery is used in conjunction with BIM in order to effectively execute and complete a fully coordinated project.

To ensure success in using BIM and IPD, we focus on integrating every facet of the project with the design team, construction team and client. This allows the entire team to collaborate with increased accuracy and efficiency from start to finish. We believe that by having the entire project team involved from the very beginning of a project is crucial to achieving a fully coordinated project on time and within budget.

As the engineering industry evolves, new technologies offer immense assistance and advantages from the design process through construction. At P2S, we are committed to learning and embracing new developments in technology and implementing them in our designs to provide better solutions for our clients. At P2S we use a number of tools that are integral to our BIM process including Revit MEP, AutoCAD MEP, IES Virtual Environment, EnergyPro, Trane Trace, and eQuest. These new project delivery forms provide a number of added benefits:

  • Encourage collaboration early in the design process
  • Improved coordination
  • Improved productivity
  • Accurate alternative costs
  • Minimize change orders
  • Minimize RFI’s
  • Increased speed of delivery

As a paradigm shift in the engineering industry, the BIM process is here to stay. This efficient design and construction process and technology allows for a more focused and efficient process where buildings are designed and built virtually, and where data is efficiently maintained and updated allowing for a better outcome in each phase of the design process.
