Credit earned upon completion of this program will be reported to CES records for all AIA members. Certificates of Completion for non-aia members are available upon request. This program is registered with AIA/CES for continuing professional education. As such, it does not include content that may be deemed or construed to be an approval or endorsement by the AIA of any material of construction or any method or manner of handling, using, distributing, or dealing in any material product. Questions related to specific materials, methods, and services will be addressed at the conclusion of this presentation. This course qualifies for HSW credit. This course qualifies for Sustainable Design credit Learning Objectives for The Future of Building Materials and Their Impact on How We Build At the end of this program, you will be able to: 1. Identify key components of IEQ and the important role they play in healing. 2. Gain a deeper understanding of the conditions which promote mold growth in buildings and passive technologies which can influence their impact. 3. Better understand the physics of volatile organic compounds and emerging technologies to help control their presence in Healthcare spaces. 4. Understand the importance of acoustics on healing and the new solutions to improve. 5. Understand the impact of vision on true healing and the technologies which will change the way we look at exterior walls. 6. Identify emerging energy saving technologies to further expand the possibilities of new designs. 2

3 Principles of Healthcare Building Envelope Design Introduction Must consider flow of heat, air, and moisture across building envelope Components of building envelope must integrate to deal with all elements The Healthcare Building Envelope Building Envelope Requirements Watertight integrity, scientific analysis of materials, and compatibility of assemblies Design professionals must address the building envelope system as a whole Design professionals must have knowledge of how materials will integrate and perform in a given assembly 3

4 Design and Construction Considerations Design Considerations Environmental conditions will determine the type of materials used and how they are assembled Maintaining the building interior at a different temperature than the environment sets up a system of causes and effects Vapor barriers are used to impede the movement of water vapor through wall systems Potential Defects and Failures Causes of Defects and Failures Unfamiliar code requirements Air barriers Continuous insulation Construction defects Unskilled labor Lack of oversight and inspections Lack of product experience Building failures Questionable construction practices Absence of connection detailing Value Engineering without analysis 4

5 Commissioning Agents Buildings are under greater forensic review than ever before Use of commissioning agents is becoming more and more common Commissioning helps ensure that building systems are: Designed, installed, tested, and capable of being operated and maintained according to the design intent and the owner's operational needs Healthcare Construction Technology Topics Indoor Air Quality (IAQ) Volatile Organic Compounds (VOC s) Mold Acoustics Visual Comfort 5

6 Healthcare Construction Technology Topics Indoor Air Quality (IAQ) Volatile Organic Compounds (VOC s) Mold Acoustics Visual Comfort What is Indoor Air Quality (IAQ) IAQ is defined as The physical, chemical, and biological characteristics of indoor air in residential and commercial buildings with no internal industrial processes or operations that can affect the comfort or health of the occupant IAQ pollution is one of the greatest risks to human health Sources VOC s, Mold, People, Furniture, etc. 6

7 Why is it important to improve Indoor Air Quality (IAQ)? 90% of our time is spent indoors Air pollution levels can be up to 100 times higher indoors than outdoors Indoor air quality affects health and productivity 50% of all respiratory illnesses are caused or aggravated by poor IAQ Poor IAQ has been linked to headaches, fatigue, concentration problems, allergies, and asthma Ventilation for Acceptable Indoor Air Quality The industry requirement is ASHRAE Standard Minimum ventilation rates are specified for new construction, as well as to improve the indoor air quality of existing buildings Maximum airborne contaminant levels are specified to maintain acceptable indoor air quality The goal is to minimize the potential for adverse health effects on occupants 7

8 ASHRAE Standard 62.1 Follow to Create Acceptable Indoor Air Quality with Controlled Ventilation Ventilation Calculate outdoor air flow rates in breathing zones Determine air distribution effectiveness Determine outdoor air flow zone requirements at diffusers Air distribution Exhaust duct location Outdoor air intake Combustion air Air stream surfaces Mold growth resistance Erosion resistance ASHRAE Standard 62.1 (Cont d) Follow to Create Acceptable Indoor Air Quality with Controlled Ventilation Contaminant capture Particulate matter removal through filtration Gas concentration monitoring Heat exchanger and finned-tube coil cleaning System moisture management Dehumidification systems Drain pans Humidifiers & water spray systems Building envelope moisture management Weather resistive barriers Vapor retarders Continuous air barriers 8
