Q

EQC: Low-emitting materials

A

lessens contamination of chemical pollutants that harm the environment

VOCs - volatile organic compounds
extended exposure can be linked to chronic health issues
short term exposure leads to irritation
goes hand-in-hand with ventilation

preferably all interior building materials are in compliance
floors, walls, ceiling
thermal/acoustic insulation
furniture

Q

EQC: Indoor Air Quality Assessment

A

set up better IAQ prior to construction completion

Option 1: California Department of Public Health Standard Method V1.1 - test air standard

Option 2: complete building “FLUSH OUT”
HVAC must operate on 100% outdoor air continuously for 2 weeks

Q

EQC: Thermal Comfort

A

improve occupant comfort and well-being

six primary factors: 
surface temperature 
air temperature
air movement 
humidity 
metabolic rate
clothing
17
Q

EQC: Thermal Comfort
PPD
PMV

A

Predicted Percentage of Dissatisfaction

Predicted Mean Vote - comfort levels based on -3 (too cold) to +3 (too hot) to collect data to produce PPD INDEX

18
Q

EQC: Thermal Comfort

Field based research

A

an adaptive model of compliance to create comfortable temperature ranges

19
Q

EQC: Interior Lighting

A

people are more productive and comfortable when have ability to control light

6 primary strategies:
limit light fixture glare (set by LIGHT RIGHT CONSORTIUM)
Use lights with a color rendering index (CRI) over 80
Use lights that have life of 24,000 hours or more
Less direct overhead lighting
specify high reflectance of surfaces (Illumination engineering society - floor 20, walls 50, ceilings 80)
design for individual patio less than 1:10

20
Q

EQC: Daylight

A

credit focuses on using ACTUAL MEASUREMENT and SIMULATED DAYLIGHT ANALYSIS

3 options:

  1. detailed design analysis and input
  2. establish actual performance
  3. computer simulation
21
Q

EQC: Quality Views

A

greater attentiveness, satisfaction, and productivity
