Table $1.$ Points for low$-$emitting materials

$2$ product categories $1$ point

$3$ product categories $2$ points

$4$ product categories $3$ points

$5$ product categories $3$ points $+$ exemplary performance

Reach $90\%$ threshold in at least three product

categories

Exemplary performance or $1$ additional point if only

$2$ points are achieved.

Problem $1$: A Project in Austin, Texas wants to achieve the credit for low$-$emitting materials under indoor environmental quality $($new construction category$).$ The project will use the following materials. The second column shows the $\%$ of compliance for each product.

Paint and coatings $60\%$

Adhesive and Sealants $80\%$

Flooring $95\%$

Wall panels $50\%$

Insulation $60\%$

Composite wood $78\%$

Ceilings $95\%$

Please answer the following:

$1.$ How many product categories have the required $\%$ of compliance according to the credit?

$2.$ How many points the project can achieve under this credit?

Problem $2$: A Project in Austin, Texas wants to achieve the credit for enhanced indoor air quality strategies under indoor environmental quality $($new construction category$).$ List down your selected required number of strategies by which you can ensure that the project can earn the highest possible points on this catergory.

Requirements

NC$,$ CS$,$ SCHOOLS, RETAIL, DATA CENTERS, WAREHOUSES & DISTRIBUTION CENTERS, HOSPITALITY, HEALTHCARE

Comply with $3$ strategies for $1$ point or $6$ strategies for $2$ points

Strategy $1.$ Entryway Systems

Install permanent entryway systems at least $10$ feet $(3$ meters$)$ long in the primary direction of travel to capture dirt and particulates entering the building at regularly used exterior entrances. Acceptable entryway systems include permanently installed grates, grilles, slotted systems that allow for cleaning underneath, rollout mats, and any other materials manufactured as entryway systems with equivalent or better performance. Maintain all on a weekly basis.

Warehouses & Distribution Centers only

Entryway systems are not required at doors leading from the exterior to the loading dock or garage but must be installed between these spaces and adjacent office areas.

Healthcare only

In addition to the entryway system, provide pressurized entryway vestibules at high$-$volume building entrances.

Strategy $2.$ Interior Cross$-$Contamination Prevention

Sufficiently exhaust each space where hazardous gases or chemicals may be present or used $($e$.$g$.,$garages, housekeeping and laundry areas, copying and printing rooms$),$ using the exhaust rates determined in EQ Prerequisite Minimum Indoor Air Quality Performance or a minimum of $0\mathrm{.}50$ cfm per square foot $(2\mathrm{.}54$ l$/$s per square meter$),$ to create negative pressure with respect to adjacent spaces when the doors to the room are closed. For each of these spaces, provide self$-$closing doors and deck$-$to$-$deck partitions or a hard$-$lid ceiling.

Strategy $3.$ Filtration of Outdoor Air

Each ventilation system that supplies outdoor air to occupied spaces must have particle filters or air$-$cleaning devices that meet one of the following filtration media requirements:

$$ Minimum efficiency reporting value $($MERV$)$ of $13$ or higher, in accordance with ASHRAE Standard $52\mathrm{.}22017$; o

$$ Equivalent filtration media class of ePM $150\%$ or higher, as defined by ISO $16890-2016,$ Particulate Air Filters for General Ventilation, Determination of the Filtration Performance. Replace all air filtration media after completion of construction and before occupancy.

Data Centers only

The above filtration media requirements are required only for ventilation systems serving regularly occupied spaces.

Strategy $4.$ Filtration of Recirculated Air

Each ventilation system that supplies recirculated air to occupied spaces must have particle filters or air$-$cleaning devices that meet one of the following filtration media requirements:

$$ minimum efficiency reporting value $($MERV$)$ of $13$ or higher, in accordance with ASHRAE Standard $52\mathrm{.}22017$; or

$$ Equivalent filtration media class of ePM $150\%$ or higher, as defined by ISO $16890-2016,$ Particulate Air Filters for General Ventilation, Determination of the Filtration Performance. Replace all air filtration media after completion of construction and before occupancy.

Data Centers only

The above filtration media requirements are required only for ventilation systems serving regularly occupied spaces.

Strategy $5.$ Increased Ventilation $15$ Percent

Increase breathing zone outdoor air ventilation rates to $95\%$ of all occupied spaces by at least $15\%$ above the minimum rates as det
