Tech session topic:  ASHRAE’s Advanced Energy Design Guides (AEDG) – Going Beyond Minimum Standards

Tech Session Speaker: ASHRAE Distinguished Lecturer, Ron Jarnagain

PDH: 3 (for the technical session)

Topic Abstract:

The Advanced Energy Design Guide (AEDG) series of documents is one of the most popular in ASHRAE’s history with well over a 500,000 copies in circulation. Focused on providing clear guidance for achieving 30% and 50% energy savings in smaller commercial buildings, the AEDGs meet the need for a large number of projects where project budgets and design professionals might be in short supply. The presenter chaired the initial AEDG for Small Offices as well as 3 additional guides and will offer perspectives on the partnership that contributed to the guides, the intent of the guides and how practitioners can apply the guides.

Energy Conservation and Efficiency – Incorporating Energy Modeling into Your Design Process

Presenters:  Jason Steinbock and Matt Swenka of The Weidt Group

Description:  As energy codes continue to raise the bar, energy modeling is becoming a fundamental design service. This course provides attendees with an understanding of different types of energy modeling and how it can be used throughout the design process and into a building’s lifespan. Modeling inputs needed from various team members to create an energy model with the appropriate level of fidelity for the design phase will be reviewed. Attendees will have the opportunity to participate in an interactive energy modeling session and gain firsthand experience how early energy modeling can impact decision making*. The course will conclude with an update of various available energy efficiency rebate programs.

Learning objectives:
1) Distinguish between the different types of energy models and the factors they take into account
2) Recognize the value energy modeling can provide to the design process
3) Interpret the environmental and financial benefits provided by energy modeling results
4) Assist clients in obtaining energy efficiency rebates to buy down the cost of implementation
*The interactive energy modeling session activity entails the use of an online energy modeling tool that has been developed by The Weidt Group.

Tech session topic: “A Holistic Overview of Technologies and Strategies to Achieve Deep Energy Reductions in Laboratories”

Speaker: ASHRAE Distinguished Lecturer, Mr. Gordon Sharp

Registration Fees:
Technical Session – $30 for ASHARE Iowa members; $50 for non-members
Dinner – Free for ASHRAE Iowa members; $20 for non-members

PDH: 3 (for the technical session)

Topic Abstract:

As we strive to build more energy efficient laboratories and vivariums, the most impactful approach is often to reduce the outside airflow. In the last few years new design approaches such as demand based control of lab air change rates, chilled beams (hydronic cooling), and VAV exhaust fan control have been successfully employed to safely reduce these lab airflows to as low as 2 ACH to cut energy consumption significantly. Although these concepts may been discussed individually in the past, this talk provides a detailed holistic discussion of how these and other energy saving technologies such as heat recovery can be combined to create a whole that is greater than the sum of the parts. A sophisticated lab energy analysis tool that can determine potential energy and capital cost savings will be used to both examine, quantify, and then compare the relative contributions of different energy savings approaches for a typical lab building in some representative climates. Several case studies will be provided including a large near net zero lab project in Abu Dhabi, UAE.

Finally, building HVAC systems naturally can degrade and building energy use can rise over time with maintenance staffs often lacking the time to analyze building performance. One solution that will also be discussed is the use of intelligent agent systems and monitoring based commissioning. These systems can be used to automatically analyze lab building energy and IEQ data, often using approaches like dashboards to help ensure long term energy savings and a healthier indoor environment.
