A Building that Performs

A building that performs is energy efficient and environmentally responsible—throughout varying seasons and extreme temperatures.

Building Science Expertise from CR-BPS

A Building Envelope refers to the barrier between the indoors and outdoors of a building. It is comprised of everything that makes up the shell of a building, and the integrity of that envelope impacts the energy consumption, comfort, and performance of a building.

At CR-BPS, our robust building science expertise is how we can guarantee performance outcomes to our customers, partners, contractors, developers, local governments, and academic partners. By focusing on all aspects a building’s system for long-term performance, our process connects the assessments we take to the solutions we implement.

Building Science Services from CR-BPS

Partnership with CR-BPS prevents costly mistakes and lost time. The end result is a more durable, sustainable and environmentally friendly project.

Building Enclosure Commissioning (BECx)

Our ongoing quality assurance process, BECx, ensures that our clients’ requirements have been successfully achieved at the completion of each project. We implement custom BECx in the predesign phase of each project and continue through occupancy and beyond.

  • BECx is not a single task clearance or a simple performance test. Instead, BECx incorporates a series of checks throughout the project timeline to ensure that quality assurance is a continual focus.
  • BECx leads to significant energy savings, emissions reduction, and cost savings.
  • BECx is used on all projects, regardless of their size and complexity in both formal and informal capacities. Informally, it diagnoses and analyzes existing problems. Formally, it is more comprehensively detailed and documented when clients contract with CR-BPS to be part of a complex project with multiple interdisciplinary teams.
Forensics & Diagnostics

Our forensics and field testing services give us the ability to investigate, diagnose, solve, and prevent building performance issues.

Our forensics and diagnostics services include:

  • moisture mapping and investigation to solve water intrusion
  • building assemblies’ damage
  • microbial or mold problems
  • air leakage rate testing (blower door)
  • infrared thermography scanning
  • building assembly analysis
  • computer modeling


Energy & Enclosure Analysis

To help achieve the most energy efficient, low carbon and durable building possible, our EA+C services provide a variety of operational and embodied energy use models, building enclosure inspections, and energy rating deliverables during both design and construction.

CR-BPS is certified in the following specialties:

Type Commercial Institutional Residential
Phius Rater X X
Phius Verifier X X
ENERGY STAR Multifamily Rater X X
Passive House Consulting X X
LCA (Life Cycle Assessments) X X
Environmental Rating System

At CR-BPS, we provides a wide variety of sustainability, resiliency/adaptation, wellness, or carbon reduction rating system services. We also counsel clients in certification requirements for many of the common ratings systems such as:

  • LEED (Leadership in Environmental and Energy Design)
  • Enterprise Green Communities and Respective Overlays
  • B3 (Building, Benchmarks and Beyond)
  • ILFI (International Living Future Institute/Living Building Challenge)
  • WELL (Health-Safety Rating)
  • Green Globes (Green Building Initiative -GBI)
  • (NGBS) ICC National Green Building Standard
  • ASHRAE 189.1
  • IgCC (International Code Councils Green Construction Code)
  • We also provide air leakage rate testing (blower door) and analysis infrared thermography scanning; thermal bypass checklist inspection; building control layer inspection (water, air, vapor, thermal); weatherization system inspection; building enclosure commissioning; combustion zone analysis; and hygrothermal and building energy modeling.
Building Science for Existing Facilities and New Designs

We diagnose, analyze, test, and verify the cause of as-built problems and/or potential design problems as early in the development of the project as possible to help our clients save money and time.

Accredited Building Science Expertise

CR-BPS is accredited through the University of Wisconsin College of Engineering as a Building Enclosure Commissioning Process Provider and accredited in Commissioning Authority + Building Enclosure with the designation of BECxP and CxA+BE
