Ventilation: Do ASHRAE 62.1 & 62.2 Ensure Good IAQ?
11-12:30 Wednesday March 14
Session Chair: Michael Bruss, Bruss Construction
Session Speaker:
Courtney Moriarta, Steven Winter Associates
Level: Intermediate, Advanced
Good ventilation design requires attention to detail of both the building envelope and the mechanical systems. ASHRAE standards 61.1 and 61.2 provide guidance for designers and builders but do they really ensure good indoor air quality? When energy efficiency is a priority, can indoor air quality be preserved? This session will offer participants insight into the fundamental design challenges related to ventilation of residential buildings large and small. A variety of real-world examples will be examined.
Tightness, IAQ, & Ventilation Effectiveness
2-3:30 Wednesday March 14
Session Chair: Richard Renner, AIA, Richard Renner Architects
Session Speakers:
William A. Turner, PE, LEED® AP, Turner Building Science & Design, LLC
Steven M. Caulfield, PE, CIH, LEED® AP, Turner Building Science & Design, LLC
Level: Intermediate
We will define and explore Indoor Air Quality issues related to building tightness and discuss the dominant driving forces for actual cases of poor indoor air quality in commercial buildings. We will then discuss various ventilation strategies for effectively dealing with known pollutant sources (including displacement ventilation in high occupancy spaces). We will focus on the goal of implementing ventilation effectiveness as a means for improving both energy efficiency and Indoor Air Quality.
Building Water Consumption
4-5:30 Wednesday March 14
Session Chair: James Petersen, PE, Petersen Engineering
Session Speaker:
David Del Porto, Ecological Engineering Group
Level: Entry, Intermediate, Advanced
Managing water use in buildings is more than simply specifying water-efficient fixtures and appliances. Today we are talking about water 'effectiveness' That is, water efficiency plus water reuse. Rainwater, treated gray water and condensate are all new sources of water that can reduce the life-cycle cost to your project.
Constant Volume HVAC Systems for Sustainable, High Performance Buildings
8:30-10:00 Thursday March 15
Session Chair: Andy Arsenault, PE, Petersen Engineering
Session Speaker:
Grahame E. Maisey, PE, LEED® AP, Building Services Consultants, Inc.
Level: Advanced
We will analyze constant and variable volume air and water systems to demonstrate how and why the HVAC industry needs to move toward constant volume systems and away from variable volume system solutions for sustainable, high performance buildings. First costs, life cycle costs and life cycle performance can all be improved with constant volume systems. Energy, maintenance and comfort can also be improved with constant volume systems.
Building Science for Green Buildings
10:30-12:00 Thursday March 15
Session Chair: Bruce Coldham, AIA, Coldham Architects
Session Speaker:
John S. Straube, PhD, Dept. of Civil Engineering & School of Architecture, University of Waterloo, Ontario
Level: Entry
This session will cover the fundamentals of building science principles that are needed to produce resource-efficient low-energy consumption buildings in a range of climate zones and occupancies. Principles will be developed into practical guidance exemplified by case studies and extensive examples. The focus will be on professionally designed residential and commercial buildings, particularly the specifying architect and engineer.
Building Heating & Energy Sources: Present & Future
2-3:30 Thursday March 15
Session Chair: Richard Trethewey, RST, Inc.
Session Speaker:
Harald Prell, Viessmann North America
Level: Entry
Without heat, there is no occupancy in a building in the Northern Hemisphere. We will look at worldwide fossil fuel predictions, emissions, and the Kyoto Protocol, as well as two distinct European markets – Great Britain and Germany. What actions could be/should be taken today for conservation. Where are the State incentives for renewable energy, possible fuel options now and in the future and the challenge for future mechanical systems to be efficient and manageable.
Designing for Maintenance & Durability
4-5:30 Thursday March 15
Session Chair: Thomas R. C. Hartman, AIA, Coldham Architects
Session Speaker:
Terry Brennan, Camroden Associates
Level: Entry
We take a few years to design and construct a building. We hope it will last hundreds of years. The more we design the building to be durable, easily maintained and easily repaired the better the quality of life for those in the building and the longer it will last. This session will cover six principles of durable design and maintainability for enclosures and mechanical equipment.
