ENERGY & SUSTAINABILITY

CONSULTING SERVICES

Energy Modeling

SSR’s energy modeling services can be used as an integral design tool to help your team achieve energy and cost savings goals. Typically, a baseline model is built, against which the project’s design can be compared and contrasted. Options for building envelope and systems can be compared to determine potential energy savings and inform the owner and design team.

Feasibility Studies / Gap Analyses

For clients considering a high performance building or project, our feasibility reports provide a snapshot of where projects stand today and present a road map to reaching their sustainability goals.

Facility Water Consulting

With increasing cost and limitations on water use and wastewater production, water efficiency is becoming extremely important for many building owners. SSR’s comprehensive approach to facility water consulting begins with a water audit, with the potential for a water efficiency investigation, efficiency implementation, and ongoing periodic water consulting services.

Net Zero Consulting

To achieve a net zero energy building, a project team utilizes a holistic approach to reducing the energy consumption, starting with the building’s physical location, moving through best practices for architectural and structural design, and highly efficient mechanical, electrical, and plumbing design. The final energy consumption estimate is then offset with a renewable energy system. SSR consults to our clients in designing their projects for Net Zero energy.

Green Building Certification Consulting

SSR’s proven process for green building certification consulting (LEED, WELL, Fitwel, Living Building Challenge, Green Globes, and others) results in expedited certification achievement and reduced costs. We have consulted on 250+ certified green buildings including new construction, existing buildings, commercial interiors, healthcare, government, sports, education, commercial, and multiple building (volume) projects.

Daylight Modeling

SSR provides modeling and consulting services to help our clients optimize daylighting in built environments to help create a connection to the outdoors for building users, maintain circadian rhythms, reduce glare, and optimize controls for energy efficiency.

Lifecycle and Carbon Analysis

Reducing carbon emissions and embodied carbon is important to managing global climate change. SSR provides lifecycle analysis and carbon reduction consulting for various building systems to help our clients achieve their carbon reduction goals.

Resiliency Assessments & Consulting

Building owners face many challenges in the long term reliability of their properties and campuses. SSR has deep expertise in assessing the resiliency of buildings and infrastructure to a range of factors including climate change, grid disruptions, and extreme weather events. We consult to our clients on potential risks and mitigation measures to help increase the sustainability of their portfolios.

Benchmarking & ASHRAE Energy Audits

An engineering energy audit/analysis strives to help facility managers and owners of existing buildings understand their building’s energy use characteristics while providing recommendations for energy and cost savings. This process offers a chance to benchmark performance against peers through the ENERGY STAR Portfolio Manager Tool. Following the guidelines provided in ASHRAE’s Procedures for Commercial Building Energy Audits, an owner can choose between Level I (Walk-through Analysis), Level II (Energy Survey and Engineering Analysis), or Level III Energy Audit (Detailed Analysis of Capital Intensive Modifications).

Commissioning Services

SSR has been in the facility commissioning business for over 20 years, having commissioned over 2,500 new and existing building projects employing new building commissioning, retro-commissioning, and monitoring-based commissioning. SSR understands the importance of systems and equipment function and integration to optimize a building for longevity and energy performance. Our Cx process consistently helps to deliver better performing buildings to our clients.

APPROACH

Our process for developing Building Energy Models (BEMs) begins with understanding the Owner’s Project Requirements (OPR) in regards to energy performance goals as well as the role in BEM in meeting those goals. We understand our clients’ critical success factors include the design, construction, and operation of high performance, cost-effective buildings that comply with local energy codes, are green building certifiable, and may even target Net Zero Energy (NZE) performance where feasible. BEM is a critical tool in meeting these goals, but waiting until the end of the design process to use it is ineffective. Therefore, our BEM process generally follows ASHRAE Standard 209-2018 “Energy Simulation Aided Design for Buildings” to promote early and iterative analysis and collaboration among the project team in order to inform design decisions and develop potential solutions to achieve those goals.

Project Kick-off and Goal-setting

In accordance with ASHRAE 209, we advocate for an energy-focused design charrette early in the design process in order to discuss how BEM would be used for the project and identify project team representatives to participate in subsequent Quality Assurance reviews of BEM inputs and outputs. Additionally, the charrette would present an opportunity to review the building function as well as the local site and climate in order to identify an initial list of project-specific passive and active

design strategies that could be analyzed as the project progresses. Finally, the charrette would discuss existing benchmarks, baselines, and performance metrics in order to establish project energy goals.

Energy performance goals can be relative or absolute in nature. For example, energy codes and LEED EA Optimize Energy Performance reward energy efficiency relative to the performance of a hypothetical baseline building. Therefore, one energy goal must be to achieve a margin of savings relative to these baselines. Furthermore, achieving NZE status or the LEED IP Integrative Process credit require establishing an absolute goal in terms of site energy use intensity (EUI), source EUI, or greenhouse gas (GHG) emissions. Consequently, the energy metrics that are reported to the team must include these at a minimum.

Design Assistance Energy Modeling

Our energy modeling workflow follows the following process throughout the design, construction, and operational phases of a project in order to assist in the evaluation of system-level and whole-building level design decisions.

While SSR has developed BEMs for all of these modeling cycles across many projects, the specific BEM scope items are tailored to individual projects based on project type, scope, and goals. On a

typical LEED project, the Load Reduction cycle most closely aligns to the analysis requirements of the LEED Integrative Process credit. In order to comply with the additional energy analysis requirements of the LEED Optimize Energy Performance credit, we usually perform the HVAC System Selection, Design Refinement, and/or Design Integration/Optimization cycles later in design. Finally, we perform the AsDesigned Energy Performance cycle in order to document compliance with LEED and/or code.

SSR is a 450-person engineering consulting firm comprised of professional engineers and designers skilled in the design of high-performance buildings. Within the firm is the Building Optimization and Sustainability (BOS) group, which specializes in sustainability consulting and building performance analysis for new and existing buildings. This team includes six highly trained and qualified energy modelers, holding licenses and credentials as Professional Engineers, Certified Energy Managers, LEED Accredited Professionals, and Building Energy Modeling Professionals (BEMP). On average, these team members typically complete 40-50 simultaneous and overlapping energy modeling projects each year, most of which include multiple iterations / modeling cycles conducted throughout the design process. Our team is trained to follow standardized tools, templates, and workflows in order to facilitate work-sharing and deliverables of consistent quality.

In order to design high performance buildings, SSR has committed to using high performance tools. Our primary tool for building energy modeling is Integrated Environmental Solutions <Virtual Environment> (IESVE). This state-of-the-art software uses one 3D analytical model that integrates numerous modules and applications, allowing us to analyze multiple building performance parameters from the same model, including climate/weather analysis, thermal comfort, solar shading, daylight

APPROACH

simulation, natural ventilation, computational fluid dynamics (CFD), HVAC load calculations and system sizing, renewable energy design, as well as wholebuilding energy performance. In IESVE, we can rapidly develop geometrically simple buildings early in design in accordance with the LEED Integrative Process credit or the Simple Box Model modeling cycle of ASHRAE Standard 209. Later in design, we can model detailed HVAC system design and control configurations to match just about anything the mechanical engineer can imagine.

That being said, we believe in the philosophy that there is no “one-size-fits-all” BEM tool. All tools have their pros and cons, and when a project requires analysis of a design that IESVE cannot sufficiently model, we will utilize other BEM tools, such as Trane TRACE 700. While TRACE 700 lacks many of the features of IESVE, there are some situations where hourly HVAC coil loads from IESVE can be transferred to TRACE 700 to model chilled water plant designs and control configurations for which IESVE doesn’t yet have the capability to model.

With modern BEM tools like IESVE, there are numerous ways to output simulation results to meet almost any need. Furthermore, when output results are needed in a form that the BEM software doesn’t natively provide, we often develop custom outputs in Microsoft Excel to better communicate BEM results and our recommendations.

When comparing ECMs, energy consumption and costs can be shown in tabular form, but providing these results graphically can be more insightful. Because our energy models are capable of modeling multiple aspects of building performance besides energy, we are capable of outputting results that illustrate daylight availability, natural ventilation potential, and thermal comfort in support of other LEED credits. For example, on a recent project for an office building, we analyzed the

benefits of daylight harvesting controls against three different glazing selections (Similar to the “Design Integration & Optimization” modeling cycle). We were able to show graphically that even though the alternate glazing selections might have saved cooling or lighting energy, those savings came at the expense of daylight quality.

APPROACH

trols,

On another project, we were able to illustrate through building performance simulation that providing insulation to the floor slab above a parking garage not only saved energy but also helped to achieve adequate thermal comfort in compliance with ASHRAE Standard 55 for the office space above.

Developing Recommendations for Energy Conservation Measures (ECMs)

BEMs provide very little value if they are only used to demonstrate compliance with energy codes or LEED at the end of a project. Instead, when used early and often throughout the design process, BEMs are one of most useful tools in designing cost-effective, high performance buildings. To accomplish this, SSR advocates for a collaborative, integrative design process that roughly aligns with the following steps in the following order:

1. Define the needs and goals of the facility during an energy charrette and incorporate into the OPR.

2. Review the building program and local site/ climate. Referring to the Commercial Building Energy Consumption Survey (CBECS) or creating a Simple Box Model in accordance with ASHRAE 209 can aid this process. The end result is a list of prioritized energy end uses as well as building-specific and climate-specific ECMs to investigate during later stages of design.

3. Apply passive design measures associated with the building envelope and internal loads in order to reduce the size of the mechanical and electrical systems or eliminate systems altogether. This step is equivalent to the LEED Integrative Process credit or the Load Reduction Modeling cycle from ASHRAE 209.

4. With loads minimized, analyze and select appropriate and efficient HVAC systems. Some efficient systems, such as chilled beams, aren’t feasible until loads have been reduced sufficiently. Then design system layouts to reduce distribution energy from fans and pumps. This step is equivalent to the HVAC System Selection Modeling cycle from ASHRAE 209.

5. Seek synergies for energy recovery and reuse and optimize the design for part-load operations through controls and demand response measures. This step is similar to the Design Refinement or Integration & Optimization modeling cycles from ASHRAE 209.

6. Explore renewable energy technologies to meet project net zero energy goals.

These steps are generally repeated at subsequent phase of design, with the analysis focusing on design questions that are most relevant to that phase. For instance, a focus on massing and orientation are more appropriate early in design when design concepts are less defined, while performing the same analysis late in design would have little real value. Furthermore, energy modeling in later design phases naturally focus on refining and optimizing the systems currently designed, since budgetary and schedule constraints rarely allow for new systems and concepts to be introduced at this time.

PROJECT TEAM COLLABORATION

SSR’s BOS team regularly works with other architectural and engineering firms, developing energy models and collaborating on developing ECMs and acting as the Owner’s Energy Advocate. In this role, we follow an iterative process of communication with other project team members in accordance with the General Modeling Cycle Requirements of ASHRAE 209. Recognizing the expertise of all project team members involved, we take time during each modeling cycle to collaborate with the project architects and engineers to discuss any ECMs that we collectively believe to be potentially beneficial and appropriate for the analysis of that modeling cycle. After the analysis is complete, we provide the results to the project team for review and discussion in order to determine which ECMs should be incorporated in the design.

Net Zero Design

SSR has provided energy modeling on numerous projects across the U.S. With regards to Net Zero Design, SSR has provided energy modeling, MEP design, commissioning, and energy consulting services for several such projects within the US. These projects include the I-55 Welcome Center Net Zero Design, Countryside City Hall and Police Headquarters, Lake County Maintenance Facility concept, Vanderbilt Child and Family Center, and a confidential corporate headquarters in the Southeastern U.S. In addition to the key activity of energy modeling for Net Zero buildings, SSR brings expertise in systems design, commissioning, energy and renewable energy consulting.\

Simplified Graphic of Net Zero Energy Design Process:

Energy modeling for Net Zero projects requires careful planning from concept through operations. For the I-55 Welcome Center Net Zero design project, we began with defining baseline energy performance based on building type/location, and the leading the project team through a methodical process to strategically reduce energy usage of the design case building. First, we assisted the team with siting and massing the building to minimize loads. If a project were an addition or renovation, we would analyze those factors applicable to the project scope.

For the I-55 Welcome Center, enclosure systems were then designed to mitigate external loads. SSR analyzed various wall, roof, window, and architectural configurations. Internal loads (such as lighting, occupant density, equipment) were then carefully considered within the design and programming requirements. Several iterations comparing MEP systems and equipment were performed, to find the most efficient systems that were life cycle effective for the building. System controls strategies, setpoints, and occupant expectations were the next critical step in optimizing building performance. After designing the most efficient project feasible within the budget, onsite PV systems were sized to offset the remaining energy usage in order to achieve a Net Zero design. During the construction phase, MEP system and enclosure commissioning were important activities to verify proper installation, function, and integration of building systems.

PROJECT EXPERIENCE

I-55: Energy Use Comparison of Bundled Energy Measures

After substantial construction completion of Net Zero projects, operations phase performance monitoring and analysis of energy efficiency is vitally important to validating and maintaining Net Zero energy status. SSR partners with our clients to optimize operations phase performance through energy modeling and/or system monitoring. No project aligns perfectly with addressing each of these steps to achieve Net Zero, and SSR collaborates with our project teams to work creatively and collaboratively to overcome issues to meet the program, budget, and schedule goals, in addition to energy efficiency.

Energy Reduction

SSR has successfully provided energy modeling for over 46 million SF of building area for LEED and nonLEED new and existing building projects. Our approach is to collaborate with every discipline within the project team to meet the project energy goals. For new construction projects, additions, and renovations, we begin each project with a simple-box model to facilitate an integrative energy efficient design process.

For a recent Vertical Expansion Project, SSR served as the energy modeler / building performance engineer. We began the energy modeling process with a simple box model to analyze climate and solar effects on the building loads. SSR studied how these loads could be minimized through massing, orientation, window-to-wall ratios on each face of the building, and architectural features. Next, SSR analyzed the benefit of south-facing window fins for shading and overhangs, and their effect on external loads.

Shading Analysis: 30 Degree South-Facing Window Fin

PROJECT EXPERIENCE

As the architectural design was developed for this project, we analyzed wall and roof system efficiencies, and glazing types and efficiencies. Internal loads are also an important factor for energy efficient design. Depending on the type of building and its equipment and occupant density, internal loads can be as significant as the external loads. For this vertical expansion project, SSR analyzed several factors for internal loads, including lighting power density, equipment type and location, comfort setpoints, plug load schedules, and occupant density. Data on the effect of external and internal loads for this project were presented in a detailed table, and graphically, for the project team to understand and rank energy efficiency measures and their effect on loads.

The above analyses are often consolidated into an A3 style reporting format to assist the project team in making critical decisions with a simplified presentation of the relevant data for the decision.

Below is an HVAC system analysis A3 reporting example. In this example, the Owner asked the project team to explore which HVAC system (in combination with architectural cost and program area impacts) would result in the lowest Total Cost of Ownership.
