Important decisions made during pre-design and conceptual design can have a big impact on operational energy use in the finished building. Quick and simple energy analysis during these phases can provide valuable information at little cost and at a time when design changes are much more easily accomplished. However, early energy analysis is not yet standard practice in the design of nonresidential buildings. In this presentation, Erik Kolderup and Dimitri Contoyannis, HVAC engineers and energy modelers, will discuss lessons learned from a recent US Department of Energy (US-DOE) funded survey of architects that looked at current energy modeling practices. They will also provide guidance on integrating energy analysis in early design, including discussion of analysis roles for both architects and specialists. Their guidance draws on best practice guidelines found in the new AIA guide Integrating Performance Simulation in the Design Process and ASHRAE Standard 209-2018 Energy Simulation Aided Design for Buildings Except Low Rise Residential Buildings.

Erik Kolderup, PE, LEED AP
Erik Kolderup, PE, LEED AP, is Principal of Kolderup Consulting based in San Francisco, California. Mr. Kolderup provides technical consulting services, focusing on the sustainable, energy efficient design and construction of commercial and institutional buildings. He identifies and evaluates design alternatives to optimize the integrated performance of a building’s systems. He employs computer simulation tools and other analysis methods to assist building designers in planning, designing, and specifying high performance systems. His experience covers envelope, lighting, daylighting, natural ventilation, and HVAC systems. His special interest is developing integrated design strategies for natural ventilation and daylighting. He is also a consulting faculty member at Stanford University teaching a class on energy efficient building design. Mr. Kolderup is based in San Francisco, California and has provided sustainability and energy consulting services since 1990, when he joined Eley Associates as an energy engineer. He became an owner in 1994 and served as vice president until the firm’s merger with Architectural Energy Corporation in 2004. After three years as Associate Principal, sharing management of AEC’s San Francisco office, Mr. Kolderup started Kolderup Consulting in 2007. He is also a consulting faculty member at Stanford University where he teaches a class on energy-efficient building systems. He holds degrees in electrical engineering and industrial engineering from Stanford University. He was a voting member of the ASHRAE Standard 209 Committee.
Dimitri Contoyannis, P.E., LEED AP, Certified Energy Manager (CEM) Mechanical Engineer, Energy Modeler, Software Development Expert President, Model Energy
Dimitri Contoyannis is President of Model Energy. Prior to founding Model Energy in February of 2019, he was Director of NORESCOs Codes and Standards team. He has more than 15 years of engineering experience and is responsible for overseeing projects with code enforcement agencies, utility companies, standards organizations, and non-profit agencies to support their aggressive energy efficiency goals. He has produced and reviewed energy models in support of utility rebate programs, LEED certification, and mechanical system design. Mr. Contoyannis also has a background in developing energy modeling tools for industry professionals. He previously worked on developing the Commercial Building Energy Modeling Guidelines and Procedures (COMNET) and led rules-based energy software development projects as an employee of Integrated Environmental Solutions (IES).
Mr. Contoyannis led NORESCOs projects with California Energy Commission (CEC) for providing technical support for Title 24 development and activities supporting the CECs Existing Buildings Energy Efficiency Action Plan. He led the project team responsible for the development of the Nonresidential Compliance Software CBECC-Com from 2011 through 2018. He is also actively involved in training CBECC-Com to the modeling community statewide and at local ASHRAE and IBPSA chapter meetings.
Elisa Jue, AIA, LEED AP B+C
Elisa Jue is a Principal at Smithgroup. Her domestic and international design experience ranges from healthcare, senior living communities, retail, mixed-use and civic buildings. Elisa believes design is human based rather than style based. Centering on the human experience makes each of her projects uniquely cater to its users and surroundings. She also believes in the importance of sustainability design, and seek innovative method to achieve both beauty and energy efficiency in her design.
AIA CES Learning Objectives: At the end of the program participants can
- Define a single aspect performance simulation and give one example of this type of simulation
- Cite two examples of how architects currently use energy modeling as reported in the IBPSA-USA study on energy modeling practices.
- Define a whole building energy performance simulation and provide one reason why specialist expertise is typically required for good results.
- Name at least two recommendations recounted by the presenters on how to define energy analysis work responsibilities between the architect and specialist energy modeler.
