Abstract

We ventilate buildings to provide acceptable indoor air quality (IAQ). Ventilation standards (such as American Society of Heating, Refrigerating, and Air-Conditioning Enginners [ASHRAE] Standard 62) specify minimum ventilation rates without taking into account the impact of those rates on IAQ. Innovative ventilation management is often a desirable element of reducing energy consumption or improving IAQ or comfort. Variable ventilation is one innovative strategy. To use variable ventilation in a way that meets standards, it is necessary to have a method for determining equivalence in terms of either ventilation or indoor air quality. This study develops methods to calculate either equivalent ventilation or equivalent IAQ. We demonstrate that equivalent ventilation can be used as the basis for dynamic ventilation control, reducing peak load and infiltration of outdoor contaminants. We also show that equivalent IAQ could allow some contaminants to exceed current standards if other contaminants are more stringently controlled.

Final Report Balancing energy conservation and occupant needs in ventilation rate standards for Big Box stores in California. Predicted indoor air quality and energy consumption using a matrix of ventilation scenarios

Technical Report Apte, Michael G. ; Mendell, Mark J. ; Sohn, Michael D. ; ...

Through mass-balance modeling of various ventilation scenarios that might satisfy the ASHRAE 62.1 Indoor Air Quality (IAQ) Procedure, we estimate indoor concentrations of contaminants of concern (COCs) in California “big box” stores, compare estimates to available thresholds, and for selected scenarios estimate differences in energy consumption. Findings are intended to inform decisions on adding performance-based approaches to ventilation rate (VR) standards for commercial buildings. Using multi-zone mass-balance models and available contaminant source rates, we estimated concentrations of 34 COCs for multiple ventilation scenarios: VRmin (0.04 cfm/ft2 ), VRmax (0.24 cfm/ft2 ), and VRmid (0.14 cfm/ft2 ). We compared COC concentrationsmore »« less

Assessment of a carbon dioxide controller for residential ventilation and indoor air quality management. Final report

Technical Report Koontz, M D ; Burruss, R P ; Cade, D R

Indoor air quality can be adversely affected by combinations of building materials, furniture, consumer products, and by such activities as cooking. Acceptable indoor air quality (IAQ) can be achieved by management of pollutant sources or by various modes of controlled or uncontrolled ventilation. Control of pollutant sources can often be difficult to achieve; however, increased ventilation can generally reduce concentrations of all indoor pollutants, usually to levels established by ASHRAE Standard 62-1989 which specifies acceptable levels of major indoor pollutants as well as ventilation rates for specific types of occupied spaces. Increased ventilation, however, is often done at a penaltymore »« less
Ventilation or filtration? The use of gas-phase air filtration for compliance with ASHRAE Standard 62

Journal Article Muller, C O ; Friedman, A B - Energy Engineering

ASHRAE Standard 62, in its current form, employs two procedures to provide acceptable indoor air quality (IAQ) in buildings. These are the Ventilation Rate and Indoor Air Quality (IAQ) Procedures. This standard further endeavors to achieve the necessary balance between IAQ and energy consumption by specifying minimum ventilation rates and IAQ that will be acceptable to human occupants. The Ventilation Rate Procedure provides only an indirect solution for the control of indoor contaminants. While it does allow for the use of cleaned, recirculated air, it does not allow the use of this air is to be used to reduce themore »« less
Evaluation of the Indoor Air Quality Procedure for Use in Retail Buildings

Technical Report Dutton, Spencer M. ; Chan, Wanyu R. ; Mendell, Mark J. ; ...

California's building efficiency standards (Title 24) mandate minimum prescribed ventilation rates (VRs) for commercial buildings. Title 24 standards currently include a prescriptive procedure similar to ASHRAE’s prescriptive “ventilation rate procedure”, but does not include an alternative procedure, akin to ASHRAE’s non-prescriptive “indoor air quality procedure” (IAQP). The IAQP determines minimum VRs based on objectively and subjectively evaluated indoor air quality (IAQ). The first primary goal of this study was to determine, in a set of California retail stores, the adequacy of Title 24 VRs and observed current measured VRs in providing the level of IAQ specified through an IAQP process,more »« less

Practical approaches for health care: Indoor air quality management

Conference Turk, A R ; Poulakos, E M

The management of indoor air quality (IAQ) is of interest to building occupants, managers, owners, and regulators alike. Whether by poor design, improper attention, inadequate maintenance or the intent to save energy, many buildings today have significantly degraded IAQ levels. Acceptable IAQ is defined by the American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE) in Standard 62-1989 {open_quotes}Ventilation for Acceptable Indoor Air Quality{close_quotes} as {open_quotes}air in which there are no known contaminants at harmful concentrations as determined by cognizant authorities and with which a substantial majority (80 percent or more) of the people exposed do not express dissatisfaction.{close_quotes}more »« less
