Conceptual Design Phase - Can Architects Do Their Own Energy Analysis and Modeling?



Online Webinar / AIA SF - 130 Sutter St. Suite 600, San Francisco, California 94104

November 25, 2019

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.

A Live Webinar is available for those unable to attend the event in person.

Erik Kolderup, PE, LEED AP, is Principal of Kolderup Consulting based in San Francisco, California. He 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 Efficiency

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.
