Design Goals for Extended stay hotel

• Green walls to purify the air.

• Waterfall/ fountain which will attract all the dirt and impurities in the air making the air quality easy to breath.

• Nontoxic materials and finishes.

• Using bamboo to remove harmful greenhouse gasses.

• Installing air purifier such as MERV 13 and HEPA filter which removes particles, such as dust, mold spores, and pollen.

• Skylight on the stairs area and other part of the hotel to enable natural light.

• Tinted glass and low-e glass with a reflective coating that reduce heat gain but allow light to pass through the glass.

• Interior vegetation gallery to enable customers to purchase plants and the money goes to donation for Clean Air Task Force.

• Technology such as INDOOR AIR QUALITY SENSORS which have Smart thermostats using remote sensors to detect the temperature and determine whether a room is occupied. The sensors are mounted on the wall or ceiling of the building and when they detect unhealthy levels of indoor air pollution, they increase ventilation.

Design Solutions

Based on the problems listed previously which is indoor air pollution the pattern use will be 1, 4, 5, 9, and 11.

Since it helps to resolve the problem of indoor air pollutants.

• Pattern 1: Integration of nature in the building,

- Plants absorb carbon dioxide and release oxygen through photosynthesis.

• Pattern 9: Provide materials, furniture and finishes that are ecology friendly.

-Using natural or environmentally-friendly, biodegradable materials such as wood or bamboo to prevent off-gassing effects on our health.

- Recycle materials which will reduce waste and air pollutants emitted from process of transportation and others.

• Pattern 4: Encourage sustainable thermal practice and airflow to positively impact air quality, well being and comfort.

Example: -Natural ventilation and particle filters

-Shading -Thermal mass

• Pattern 11: Reduce stress and improve comfort through spacial attribution which help to reduce hazard from indoor air pollutant.

Example: high ceiling, balconies, open floor plan

• Pattern 5: The presence of water attract impurities in the air to support healthy brain and body function.

Example: Waterfall and fountain.

Sustainable practices evaluated by LEED V4.1

Based on the LEED v4.1 ID_C_Guide we will apply some design strategy

enhanced Indoor Air Quality which include:

Strategy 1: Entryway Systems

• Install permanent entryway systems such as grates, grilles, slotted systems that allow for cleaning underneath, at least 10 feet long in the primary direction of travel to capture dirt and particulates entering the building at regularly used exterior.

Strategy 2. Interior Cross-Contamination Prevention

• Sufficiently exhaust each space where hazardous gases or chemicals may be present or used.

• a minimum of 0.50 cfm per square foot to create negative pressure with respect to adjacent spaces when the doors to the room are closed.

• For each of these spaces, we will provide self-closing doors and a hard-lid ceiling to prevent fumes or gasses from penetrating an adjacent space.

Strategy 3. Filtration of Outdoor Air

• Minimum efficiency reporting value MERV of 13 or higher filter, which is at least 85% efficient at capturing particles in 1 µm to 3 µm size range. in accordance with ASHRAE Standard 52.2–2017.

Strategy 4. Operable windows

• 75% of the regularly occupied spaces have operable windows that provide access to outdoor air.

• 6.4.1.1 Single Side Opening for spaces with operable openings on one side of the space, the maximum distance from the operable openings shall be not more than 2H the ceiling height

• 6.4.1.3 Corner Openings. For spaces with operable openings on two adjacent sides of a space, the maximum distance from the operable openings shall be not more than 5H along a line drawn between the two openings that are farthest apart.
