Air leakage control is an integral to the durability and energy efficiency of buildings. Because of the importance of air leakage control, multiple standards and code requirements have been developed to ensure that air leakage control is effectively employed. These include material and assembly specifications, as well as whole building testing and leakage site diagnostic tests. This presentation will tell the story of the development of code requirements from early non-specific mentions of air leakage control to the current requirements with specific criteria. The air leakage criteria in the International Energy Conservation Code (IECC), ASHRAE 90.1 and ASHRAE 189.1/International Green Construction Code (IgCC) will be discussed. This presentation will also describe the development of whole building testing as it evolved from a research tool to a performance validation method. Finally, a preview of possible future code and standards development will be provided.

Session 2: The Interrelationship of HVAC Systems, Enclosure Air Barrier Systems, and Indoor Air Quality
Society’s awareness of the role the built environment plays on indoor air quality has greatly increased in the wake of the COVID-19 pandemic, prompting interest by many different professionals, including employers, owners and commercial real estate entities. In turn, industry organizations, such as the American Society of Heating and Refrigerating and Air-Conditioning Engineers (ASHRAE) continue to refine guidelines for design, construction, and operations professionals. Guidance impacts airflow strategies, pressurization control, as well as temperature and humidity controls, all of which have direct impacts on the building enclosure. One notable consideration is related to elevating the interior humidity. However, an existing enclosure may not have been designed or constructed to accommodate such an operational change without the potential risk of condensation depending on the location and climate. Additionally, a poor performing enclosure can limit the success of mechanical interventions. This presentation will discuss the related highlights from recent research, as well as considerations for design, renovation, commissioning, and operation. Perspectives from enclosure design professionals, as well as mechanical engineers will be provided.

Session 3: Building Science Considerations for HVAC and Enclosure Interaction and High Performance Buildings C
Many building types are designed, especially in the commercial office field, as a cold dark shell where interior tenant fit out will occur later. Many aspects of the fit out such as final HVAC system layout, partition wall locations, location of larger assembly spaces like conference rooms or other amenities may not be fully defined at the same time as the core and shell. If tenant spaces are designed separately from the core and shell, the disconnect between the two designs may unintentionally impact the comfort of the interior space where it does not perform at a high level. Additionally, specialty spaces like sports facilities, natatoriums and museums have additional considerations for how HVAC interacts with the people and their use of a space.
As people utilize and move through the space, they are constantly being impacted by the building physics of the interior environment. This includes moisture and heat transfer across their skin. Clothing and footwear can impact a person’s overall comfort within the space based on how heat transfers through these and in some cases, moisture load within the space. System furniture, layout of structure, and HVAC system type and distribution can also affect a person’s comfort by adversely impacting the intended building enclosure performance. As the art and science of building design becomes more complex, it is necessary for designers to maintain a suitable proficiency in both these spheres and understand how different building systems interact. The wealth of scientific and technical data relating to the performance of buildings is one of contemporary architecture’s primary assets. This talk will cover the aspects of heat, air, and moisture transfer that impact our built environment, and the interaction of HVAC with interior spaces, enclosure systems, and people. The speaker will use examples from several projects to identify the concerns and practical solutions that can be implemented to improve a person’s comfort within interior spaces.

Energy performance standards such as those found in Passive House, and more recently, regional building codes including the 2020 NYC Energy Conservation Code and the 2017 DC Energy Conservation Code are requiring designers to account for thermal bridges in building enclosure design. Many resources and procedures exist for evaluating heat flow through thermal bridges and their impact on the overall U-factor of enclosure assemblies. Generic details, numerical calculation methods, and computer-aided simulation approaches are readily available for this purpose. This presentation will provide an overview of some of the more recent developments regarding energy standard and building code requirements associated with thermal bridging and various methodologies used to evaluate thermal bridges in building enclosure design.

The Smith College Neilson Library project is a recently completed renovation, subtraction, and addition to the original 1909 Neilson Library building and its subsequent additions. The project had ambitious performance and sustainability goals that were realized in part by a custom designed mass timber curtainwall system. The creation of the curtainwall system took integrated effort; from design intent, to design assist, through construction, and ultimately to project completion. There were many hurdles along the way that took the full design and construction team to overcome. In the end the system and the project lived up to the aspirational vision and performance goals desired by Smith College, including a high level of airtightness as demonstrated by whole building air leakage testing. This session will explore the process that it took to create the curtain wall system, overcome the many challenges, and achieve the desired outcome.

Owners and managers of existing masonry buildings often are reluctant to adopt increased thermal insulation in their buildings for fear of freeze-thaw damage. How well supported are those fears? The physics of ice and water shows that damage to water-containing materials subject to freezing occurs due to increase in fluid pressure, which requires complete containment of water and almost complete absence of air. These conditions, while possible in the laboratory, are essentially impossible in field masonry, even when subject to naturally-occurring water saturation. It is logically impossible to design a field survey capable of proving the absence of “freeze-thaw” damage to existing masonry. There are several approaches that permit evaluation of masonry condition where freezing temperature may or may not play a role. These will be presented.

New England’s healthcare facilities tend to be 50+ years old and located in urban settings. Due to location, construction of new facilities is limited and costly. An alternate option is to improve the existing facility with the installation of a new building enclosure assembly. Challenges include full interior occupancy during construction, and installation of a new structural support system. This presentation will review the installation of a new rainscreen, wall cladding, and window system over an existing multi-wythe masonry wall. It will provide an in-depth examination of design considerations, with a focus on addressing ongoing air and moisture infiltration caused by the lack of continuous air barriers and thermal insulation. The presentation will also discuss unique solutions to improve the overall building performances and aesthetics, while coordinating construction in an occupied facility. The presenters will conclude the presentation with a detailed case study of a Boston area hospital.

Session 8: Energy Code Documentation for Achieving High-performance Building Enclosures and Commissioning to Achieve Durability
Closing the “performance gap” between predicted energy consumption versus actual and further reducing energy consumption will require a multifaceted effort. A portion of this gap can be attributed to inaccurate thermal and airtightness analysis of the building enclosure. As we aspire to deliver net-zero and carbon positive buildings, the accuracy of energy modeling and underlying input data is even more important. Building enclosure energy code compliance documentation, now required in some jurisdictions, takes the form of “EN” drawings, similar to drawings that illustrate compliance with the zoning and building codes. This presentation will illustrate methods for this documentation of the building enclosure and how the documentation process itself can lead to more accurate energy models, more energy efficient buildings, and better control of risk for architects.

The process of Building Enclosure Commissioning (BECx) is designed to ensure a building’s exterior enclosure meets the Owner’s Project Requirements (OPR). How can the BECx process—design and specification review, field observation, and testing—provide assurance that materials and assemblies will meet life-service goals? This presentation examines the relationship of BECx activities to constructed results using case studies of both new and existing buildings as examples. Design Review: Durability is assessed by both micro and macro level reviews of deterioration mechanisms in the context of placement. Materials and assemblies are evaluated against environment specific conditions such as temperature, moisture, UV, storms, and salinity. The potential harm imparted by animals is similarly considered. Construction Observation and Testing: We will review procedures commonly employed to verify the viability of an enclosure in terms of durability. A variety of available lab and field tests for materials and assemblies at various locations within a wall system will be discussed in terms of their ability to assess durability. Value and Practicality: Owner’s want value based solutions. This presentation will explore an evaluation matrix with factors of relative cost, constructability, accessibility, and maintainability to help Owner’s assess the relationship of cost to life service and durability.
