keynote speakers


dirk lohan

Founder/Principal, Lohan Anderson

Dirk Lohan, together with Floyd D. Anderson, is a founder of Lohan Anderson, and is responsible for the firm’s designs and long-term development.

Mr. Lohan has established Lohan Anderson with his philosophy that successful architecture must respond not only to economic constraints but also to the larger social and physical conditions. During the past 40 years, Dirk Lohan has practiced and evaluated the tenets of this philosophy. Looking to the future, Mr. Lohan’s philosophy is even more relevant today due to the rapid changes in technology, the growing importance of environmental concerns and the impact of globalization on the life and work of all people.

Dirk Lohan left his native Germany to begin his architectural studies at the Illinois Institute of Technology under the tutelage of his grandfather, Mies van der Rohe. He returned to Germany and finished his studies in architecture and planning at the Technische Hochschule (Diplom – Ingenieur) in Munich in 1962. When Mr. Lohan returned to Chicago, he worked closely with Mies on such projects as the New National Gallery in Berlin, the IBM office building in Chicago and The Toronto Dominion Centre.

Prior to the establishment of Lohan Anderson, Mr. Lohan was the senior principal of Lohan Associates. Under his leadership, the firm produced an impressive portfolio of design solutions including such projects as the McDonald’s Corporate Headquarters Campus, the John G. Shedd Oceanarium, and the Sinai Temple as well as national and international projects.

Mr. Lohan firmly believes that successful projects and satisfied clients are the result of well-detailed, functional and innovative yet timeless design. Throughout his career, Mr. Lohan has successfully humanized the traditional modernism of the fifties and sixties by infusing variety and texture to enrich each building design. Dirk Lohan’s achievements in architecture have been recognized with many awards including his appointment as a fellow in 1983 by the American Institute of Architects.

As the Senior Leader of the firm, Dirk Lohan is involved in almost all projects with particular emphasis on the design direction each project might take. He is assuring that Lohan Anderson continues to provide professional services that are in keeping with the philosophy and integrity that he established as the firm’s core principles.

Dirk Lohan currently serves on the Board of the Illinois Institute of Technology, the Board of Overseer’s of College of Architecture at IIT and the Board of Directors of Chicago Maritime Museum.

jeremy attema

SJSU Student

Jeremy started his professional career working in the mortgage industry. During this time, he became aware of the necessity in changing the way we currently build and finance our homes. After volunteering with USGBC councils, he decided to go back to school to obtain a Masters in urban planning while focusing on sustainability and the built environment. He was introduced to the concept of Passive House building after noticing a conference flyer at a local Santa Cruz, CA brewery. Upon attending the conference in 2013, he met and spoke with, presenter, CPHC Graham Irwin. Irwin’s research aspirations and Jeremy’s academic goals aligned and they sought out to complete a rigorous analysis to compare Passive House designs to California code minimum requirements in all 16 California climate zones. Irwin completed the energy models and designs while Jeremy started accumulating data to complete a life cycle cost analysis for single-story single family buildings. The research looked at electric and natural gas heating and cooling strategies to examine if the initial investments of PH design strategies could be recouped within 30 years using a discounted cash flow analysis in the many California climates. A cost survey was sent to multiple CPHCs and PHCBs to culminate a mean average cost for the PH designs created by Irwin. Results examine the relationship of HDD and CDD, availability of rebates and incentives, the cost of energy, and energy escalation rates to the feasibility of a PH from a cost perspective, as well as examining an interesting design decision between whole house fans or air conditioning units.

bluestone steve  

steve bluestone

The Bluestone Organization

Steve is a partner in The Bluestone Organization, a third generation 88 year old family business based in NY (founded by his grandfather) that develops, builds, owns and manages multi-family apartment buildings. His interest in energy efficiency first began in the mid-late 70’s as the country struggled to cope in the aftermath of the 1973 Arab Oil Embargo. After a couple of years spent in architecture school, he decided to pursue his goal of building better buildings by getting his hands dirty for a couple of decades out in the field that enabled him to learn what worked, and more importantly, what didn’t work. For the past ten years or so, Steve has led his firm’s shift away from constructing typical buildings to developing some of the largest high performance buildings in the NYC area at little to no extra cost. The firm broke ground in June of 2015 on a 7 story, 101 unit affordable Passive House rental apartment building that is calculated to achieve certification at 0% to less than 1% extra in costs of comparable buildings. As part of the “Build It Back” Superstorm Sandy recovery initiative, four houses they are building in Staten Island are targeted for Passive House certification, and certification is also targeted for a 16 story 249 unit market rate rental building located just north of NYC that they will break ground on later this year.

Baxt Ingui Architects

Michael Ingui and the team at Baxt Ingui Architects are completing a number of houses that are targeting passive House Certification. A number of the houses are also targeting LEED certification and net zero and most of the houses are in NYC Landmark designated districts. The detailing and specifications developed though Passive House projects have affected all of the firms projects allowing even non-certifiable houses to cut the cooling and heating needs by more than ½ while creating quieter and healthier environments.

Our collaborative design process begins with our clients and extends to the entire building team. By fostering an open dialogue and sharing knowledge among people we work with across many projects, we are helping to build a community of contractors and consultants that are able to solve complex installations with innovative solutions. Every successful project and every successful detail revision is making Passive House easier to build for our contractors and more economically feasible for our clients.

Baxt Ingui’s experience and knowledge with Passive House building has fundamentally changed the way we approach our projects. Even on our projects that will not be Passive House Certified, we have been able to cut the need for heating and cooling by more than half in some cases. We have learned that building smarter and more energy efficient can be incorporated into any project while continuing to create beautiful, well-crafted, and unique homes.

Stones Throw Design

Terrell Wong is an architect with over 25 years experience. Her passion for the environment and design has greatly influenced her career. In 2006, Terrell lead the winning team to the National Archetype Sustainable House Award. Their “Building Blocks” modular home concept was constructed at the Toronto and Region Conservation Authority’s Kortright Centre as a showcase for sustainable design.

In 2009, Terrell was a founding member and President of Passive Buildings Canada, a national membership-based, non-profit organization that promotes the Passive House concept.

Terrell’s firm, Stone’s Throw Design Inc., specializes in low energy residential design. With its focus on building science, the firm creates designs utilizing cutting edge materials and techniques. In 2011, they completed the first insulated rammed earth house in Ontario. This 350m2 building has a total heating load of 25kWh/m2 and total primary energy use of 100kWh/m2 based on the Passive House criteria. This constitutes 1/10th of the energy usage of a comparably sized home. In 2014 the firm fought for the right to build a two storey strawbale addition in the Beaches area of Toronto. The project was completed in the Fall. Stones Throw Design Inc. is a full service firm that partners with its clients to provide cost effective design and energy solutions.

In 2014, Terrell published Passive Buildings in Canada. This book is a snapshot in time of these buildings in Canada. The goal is to present these excellent designs in an easily comprehensible way to architect, engineer, builder and future home owners alike. This book encompasses buildings from British Columbia to Nova Scotia and building types as diverse as single family dwellings to high rises.
