Abstract

BSC TO5 Task 2.1 Field Testing of Compartmentalization Methods for Multifamily Construction - Capitol Heights, MD 20743 A building comprising five vertical townhome units was built in the Washington, D.C., area; the townhomes were three-story slab-on-grade units (1700-2000 ft2) with a rear-facing "tuck under" garage. The three-story townhome design results in 3 ACH50 being equivalent to a stringent surface-area based target (0.16-0.17 CFM50/ft2 building enclosure). The party walls between units were area separation walls, with a 2-hour fire resistance rating (Underwriters Laboratories U347 assembly; equivalent to U373 and U336). This assembly has a 1-in. vertical air cavity on each side of a 2-in. vertical gypsum panel in the middle of the assembly, resulting in an airflow network that is connected over multiple floors (despite nominal draft stopping), and has potential connections to exterior conditions. The test townhomes were built with several experimental airtightness details, including taping of exterior sheathing as an air barrier closure detail (in particular, at area separation walls). Various measures were applied to the units for this experiment, including a "control" conventional construction unit and some units with "improved" detailing (without taped sheathing).

Field Testing of Compartmentalization Methods for Multifamily Construction

Technical Report Ueno, K. ; Lstiburek, J.

The 2012 IECC has an airtightness requirement of 3 air changes per hour at 50 Pascals test pressure for both single-family and multifamily construction in Climate Zones 3-8. Other programs (LEED, ASHRAE 189, ASHRAE 62.2) have similar or tighter compartmentalization requirements, driving the need for easier and more effective methods of compartmentalization in multifamily buildings. Builders and practitioners have found that fire-resistance rated wall assemblies are a major source of difficulty in air sealing/compartmentalization, particularly in townhouse construction. This problem is exacerbated when garages are “tucked in” to the units and living space is located over the garages. In thismore »« less
Field Testing of Compartmentalization Methods for Multifamily Construction

Technical Report Ueno, K. ; Lstiburek, J. W.

The 2012 International Energy Conservation Code (IECC) has an airtightness requirement of 3 air changes per hour at 50 Pascals test pressure (3 ACH50) for single-family and multifamily construction (in climate zones 3–8). The Leadership in Energy & Environmental Design certification program and ASHRAE Standard 189 have comparable compartmentalization requirements. ASHRAE Standard 62.2 will soon be responsible for all multifamily ventilation requirements (low rise and high rise); it has an exceptionally stringent compartmentalization requirement. These code and program requirements are driving the need for easier and more effective methods of compartmentalization in multifamily buildings.
Metrobus Survey - Washington DC - 2014

Dataset Team, TSDC

The primary purposes of the survey were to update ridership by the jurisdiction of residence for use in Metrobus’ operating subsidy allocation and to collect demographic, travel, and access data for Title VI compliance, system planning, and operation analyses. It was not a customer opinion survey; the focus was on ridership and travel characteristics.

Technology Solutions Case Study: Field Testing of Compartmentalization Methods for Multifamily Construction

Program Document

Fire-resistance rated (or area separation) wall assemblies present a great difficulty in air sealing/compartmentalization, particularly in townhouse construction. To address this challenge, Building Science Corporation partnered with builder K. Hovnanian Homes to determine whether taping exterior sheathing details improves air sealing in townhouse and multifamily construction, and to better understand air leakage pathways.
