ASHRAE Distinguished Lecturer’s Talk Towards Energy Efficiency: Energy Audit and Building Commissioning

ASHRAE Distinguished Lecturer’s Talk Towards Energy Efficiency: Energy Audit and Building Commissioning

Synopsis

Topic 1: Energy Audits: The basics of setting up and executing energy audits in commercial buildings ASHRAE Standard 211-2018 and its predecessor publication Procedures for Commercial Energy Audits are used in this presentation that goes step by step in the required process of making energy audits, Level I, II, and III. It highlights several economic procedures used in energy audits. It shows many resources that can be used including ASHRAE Standard 100 and ASHRAE Building EQ program energy conservation measure recommendations. It highlights example energy and economic evaluation calculations about energy saving opportunities available in a typical building audit including renewables. NZEB buildings are discussed. This presentation also includes a brief discussion about of other related ASHRAE Energy products and services, such as Standards 90,100,189, Performance Measurement Protocols, Energy Efficiency Guide for Existing Buildings, Energy Targets, and the ASHRAE Building EQ Building Labeling program tie in to providing best practices.

Topic 2: Testing Adjusting and Balancing (TAB) – HVAC This talk is about TAB work and its relation to HVAC; it starts with the measurement basics and the instruments that are used in TAB work, including some of the forms used. The presentation shows the technical equations and solutions related to real problems used in the field. The fan and pump laws are presented and solved in many real-world word problems. The simple process about how TAB performs its site visits and balancing efforts are demonstrated and discussed. Both Air and Water TAB work is explained. Psychrometrics, Particulate measurements, Noise and vibration topics are also briefly discussed. TAB work uses ASHRAE standards as well as Industry procedural standards such as produced by AABC and NEBB. In general, it gives a basic overview of the TAB process for air and water systems, and how it is used to validate and confirm that the design parameters are being delivered and documented to the project.

Topic 3: Building Commissioning in the Built Environment - Principles, Process, Procedures, and the Future This talk is about HVAC&R commissioning basics and highlighting our ASHRAE Standard 300 series, 202,230P, Guideline 0 and 0.2, and sample commissioning project applications and photos. It teaches about what Commissioning is and what it is not. Some sample subjects can include:

• HVAC/R-General • Smoke control and NFPA 909

• Radiant heating and cooling using DOAS

• Clean rooms; OR’s; Procedure and Isolation rooms.

• Pharmaceutical Manufacturing and Production; Drug Mixing areas.

• Air tightness testing; Case study examples using Blower doors and site AHU’s

• Energy Monitoring Systems; Btu and Kw

• Total Building Commissioning

• Enclosure/Envelope commissioning and associated method of testing

• Thermal/Ice Storage Chilled Water Systems

• Existing buildings in hot-humid climates

• Lighting controls where required by contract or code.

It explains the industry importance of commissioning and why we use it, how it works, and speaks about its many features and benefits. It is important to note that ASHRAE Cx standards are process documents and can be adapted to be used in many other commissioning disciplines. As a current voting member of the Standard 300 group, and practicing CxA/CxP and ASHRAE Certified CPMP, it outlines better and best practices in commissioning activities, using ASHRAE commissioning related Guidelines. Each chapter of the new ASHRAE standard is explained. As the past chair, it explains the activities of the Presidential Ad Hoc Building Performance Alliance Committee on Commissioning, where we are working with all of the Industry giants (ASHRAE, ICC, USGBC, AIA, NIBS, SMACNA, AABC/ACG, NEBB, BCA, TABB, CAMEE, NEMIC, BOMA, etc.) to establish high level strategic directions for “Commissioning”, and its use and proliferation throughout our Industry, in collaboration with our Industry partners.
