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.

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.

Update on Refrigerants: Past, Present and Future:
In recent decades, the refrigeration and air conditioning sciences have been in a state of flux primarily because of the phase-out of ozone-depleting CFC and HCFC refrigerants, and secondarily because of environmental concerns related to the direct global warming impacts of some of the replacement refrigerants.  Due to these concerns, there is significant worldwide interest in using substances that are naturally occurring in the biosphere as refrigerants, which are considered benign to the environment and are termed “natural working fluids”.  Surprisingly, many of these substances were already used as refrigerants at the dawn of the refrigeration technology in the late 1800’s.   Thus, when looking at the refrigerants of the future, it is essential to understand which substances have been used in past.  This presentation provides a detailed review of the past and present refrigerants, and proposes refrigerants and their respective technologies that could be used in the future.  An assessment of their characteristics related to choice of one versus another, and an identification of trends set by these choices will be made.

How To Implement Demand Control Ventilation & Comply with ASHRAE Standards
Time: 2 pm – 2:50 pm CST
ASHRAE Standards 90.1 and 189P require demand control ventilation in some instances. ASHRAE Standard 62.1 allows demand control ventilation but places restrictions on its application. Many existing installations do not comply with the requirements of ASHRAE Standard 62.1. What is required and what strategies and technologies can be used to meet the requirements of all the standards?

Using ASHRAE Standard 62.1-2010 Multiple Spaces Equations
Time: 3 pm – 3:50 pm CST
Use of the multiple spaces equation is now a code requirement in many areas and is a requirement of LEED for any new building that uses multiple space ventilation systems. Why is the equation there? How do you use the equations? What are the two options? Does the system approach make a difference in the quantity of outdoor air required? This presentation offers answers and discussion points for these important questions.

Retro-commissioning for Energy Savings
Time: 4 pm – 4:50 pm CST
What is retro-commissioning? Is it required by LEED? How can a process save energy? What are some of the aspects of an energy saving retro-commissioning application? What guidance is available from ASHRAE guidelines? What are the types of savings from the process and what are the critical components to assure that savings are realized?
