Leadership in Energy and Environmental Design
Indoor Environmental Quality
Carbon Dioxide Monitoring - Carbon dioxide sensors are located in gathering
areas, classrooms, conference rooms, group offices, large group study rooms,
and return air vents. They are connected to the building automation system
to assure that sufficient fresh air is brought into the building during periods
of high student and staff occupancy.
Ventilation Effectiveness
Construction Indoor Air Quality Management Plan - The project team focused
on establishing and maintaining good indoor air quality with the preparation
and implementation of an IAQ management plan that addressed the specific demands
of this project and meet the SMACNA best guidelines. The basic measures included
protecting adjacent building occupants from poor air quality often resulting
from construction operations and new building materials.
Low-Emitting Materials - Interior construction adhesives, paints, and carpet
were selected to minimize indoor air contaminants that are odorous or potentially
irritating to installer and occupant health and comfort. Materials with low
volatile organic compounds (VOC) were installed and the building opened without
the traditional "new building" smell.
Indoor Pollutant Control - Foot grills and walk-off mats are installed at
all building entrances. Dirt is trapped prior to entering the building. Rooms
with chemical use are contained and vented independently of other occupied
areas.
Thermal Comfort : Comply with ASHRAE 55-1992 - The James B. Duke Library is
designed to comply with the standards of ASHRAE 55-1992 which identifies thermal
comfort standards including humidity control within established ranges per
climate zone.
Thermal Comfort: Permanent Monitoring System - A permanent temperature and
humidity monitoring system has been installed that provides operators control
over thermal comfort performance and effectiveness of humidification and dehumidification
systems in the building.
