To provide design teams and projects the opportunity to be awarded points for exceptional performance above the requirements set by the LEED Green Building Rating System and/or innovative performance in Green Building categories not specially addressed by the LEED Green Building Rating Sytem.

Requirements

Credit 1.1 (1 point): Identify the intent of the proposed innovation Credit, the proposed requirement for compliance, the proposed submittal to demonstrate compliance, and the design approach (strategies) that might be used to meet the requirements.

Credit 1.2 ~ 1.4 (1 point) same as C1.1

1.room areas

2.window areas (window areas above 2.3 m are considered to be daylight glazing. 0.75-2.3m window areas are considered as vision glazing)

3. Geometry and height factors

4. Visible transmittance

5. Daylight factor= (window area/Floor areas)* window geometry* (Actual T vis/Minimum Tvis)* window height factor

6. If the total daylight factor for a room is 2% or greater. it is appilicable

7. applicable rooms areas/ all occupied rooms > 75%, It passed the credit.

Provide for the building occupants a connection between indoor spaces and the outdoors through the introduction of daylight and views into the regularly occupied areas of the buildings.

Requirements:

- Achieve direct line of sight to vision glazing for building occupants in 90% of all regularly occupied areas.

- Areas directly connected to perimeter windows must have a glazing-to-floor area ratio of at least 0.07.

- Parts of the floor area with horizontal view angles of less than 10 degrees  at 1.7m (50 inches) above the floor cannot be included in this calculation.

- Areas not directly connected to perimeter windows must have a horizontal  view angle of at least 10 degrees at 1.27 m (50 inches) above the floor involving 50% or more of the floor area. If a room meets these requirements then the entire room area is considered to meet the view requirement.

- Exceptions will be considered on their merits.

Provide for the building occupants a connection between indoor spaces and the outdoors through the introduction of daylight and views into the regularly occupied areas of the building.

Requirements:

Achieve a minimum Daylight Factor of 2% (excluding all direct sunlight penetration) or achieve at least 250 lux in 75% of all regularly occupied areas, with the aid of a computer simulation model. Exceptions for areas where taks would be hindered by the use of daylight will be considered on their merit.

Provide a thermally comfortable environment that supports the productivity and well-being of building occupants.

Requirements:

Provide a permanent monitoring system to ensure building performance to the desired comfort criteria as determined by EQ Credit 7.1, thermal comfort- compliance

Predicted Mean Vote / Predicted Percentage Dissatisfied (PMV/PPD) based on “operative temperature”

Winter: 20-23 C

Summer: 22- 26 C

Requirements:
Comply with ASHRAE standard 55-2004, Thermal Comfort conditions for human occupancy

Provide a high level of thermal, ventilation and lighting system control by individual occupants or specific groups in multi-occupant spaces (i.e. classrooms or conference areas) to promote the productivity, comfort and well-being of building occupants.

Requirements:

Provide controls for each , individual for airflow, temperature and lighting for at least 50% of the occupants in non-perimeter, regularly occupied areas.

Caculations

1. 4.5 m offset from the outer wall: Perimeter space

2. Perimeter area: occupied areas

3. Non-perimeter area: 4.5 m from perimeter wall

4. Intersect: 75%+ perimeter area,  75%-: only area within 4.5 m offset line is considered as perimeter area.

5.

one operable window, one lighting control/18.5m2 perimeter area

For non-perimeter group multi-occupant space

930-m2(10000 ft2) : 3 lighting controls, 1 airflow control, 1 temperature control /230 m2 (2500 ft2)

930+ m2 (10000 ft2): 3 lighting controls, 1 airflow control and 1 temperature control /930m2

Provide a high level of thermal, ventilation and lighting system control by individual occupants or specific groups in multi-occupant spaces (i.e. classrooms or conference areas) to promote the productivity, comfort and well-being of building occupants.

Requirements:

Provide at least an average of one operable window and one lighting control zone per 18.5 m2 (200 ft2) for all regularly occupied areas within 5 meters (15feet) of perimeter wall.

Minimize exposure of building occupants to potentially hazardous particulates, biological contaminants and chemical pollutants that adversely impact air and water quality.

Requirements:

Design to minimize pollutant cross-contamination of regularly occupied areas:

- Employ permanent entryway systems (grills, grates, etc.) to capture dirt, particulates, etc. from entering the building at all high volum entryways.

- Where hazardous gases or chemicals may be present or used (including garages, housekeeping/laundry areas, and copying/printing rooms), provide segregated areas with deck to deck partitions with separate ouside exhaust at a rate of at least 9.2 m3/hour. m2, (0.5 cpm/ft2), no air re-circulation, and operated at a negative pressure compared with the surrounding spaces of at least an average of 5 Pa and with a minimum of 1Pa when the doors to the rooms are closed.

- Provide containment drains plumbed fro appropriate disposal of hazardous liquid wastes in places where water and chemical  concentrate mixing occurs for maintenance or laboratory purposes.

-Replace all filtration media immediately prior to occupancy. Filtration media shall have a minimum efficiency reporting value (MERV) of 13, as determined by ASHRAE 52.2-1999 for media installed at the end of construction.
