Abstract

Conservation measures that seal a building, like storm window installation, can significantly reduce its energy requirements. These measures also protect its occupants from air pollutants having outdoor sources but amplify any harmful effects of those generated indoors. Using these Fourier series techniques and an approximation of outdoor pollution peaks by step functions, we obtained the following results: the average daily concentration indoors is the same as outdoors for any pollutant with no indoor sinks if inside and outside air are assumed uniform (that is, well mixed). However, lowering a building's air exchange rate 4-fold will still protect its occupants from outdoor pollution sources, but only if the outdoor peak or variation above its average is much greater than its average, and the peak is short-lived.

Reducing indoor residential exposures to outdoor pollutants

Technical Report Sherman, Max; Matson, Nance

The basic strategy for providing indoor air quality in residences is to dilute indoor sources with outdoor air. This strategy assumes that the outdoor air does not have pollutants at harmful levels or that the outdoor air is, at least, less polluted than the indoor air. When this is not the case, different strategies need to be employed to ensure adequate air quality in the indoor environment. These strategies include ventilation systems, filtration and other measures. These strategies can be used for several types of outdoor pollution, including smog, particulates and toxic air pollutants. This report reviews the impacts thatmore »« less

Indoor air pollution in the residential environment. Volume I. Data collection, analysis and interpretation. Final report

Technical Report Moschandreas, D; Stark, J; McFadden, J; ...

A 24-month study was undertaken to characterize the indoor residential air quality. Seventeen residential dwellings were monitored, each for a 14-day period. Air samples were collected from four locations: one outdoor site adjacent to the building; and three indoor sites, the kitchen, bedroom, and living room. 'Continuous' sampling was carried out for CO, SO2, NO, NO2, CO2, O3, CH4, and THC. TSP, RSP, SO/sub 4/, NO/sub 3/, Pb, ammonia, and aldehydes were monitored intermittently. Aerosol samples were collected for elemental analysis by the Proton Induced X-ray Emission (PIXE) technique. In addition, data on energy parameters, infiltration rates, and family activitiesmore »« less
Assessing Occupant and Outdoor Air Impacts on Indoor Air Quality in New California Homes

Conference Walker, IS; Singer, B; Chan, W; ...

In 2008 the State of California adopted new building codes that required the use of mechanical ventilation systems in homes that meet the requirements of ASHRAE Standard 62.2. The standard requires both a dwelling unit mechanical ventilation system and exhaust fans in kitchens and bathrooms. A field study was undertaken to evaluate the IAQ and ventilation performance of homes built to these requirements. For ventilation system performance, the airflows of all mechanical ventilation systems were measured and their use was monitored for a one-week period. To evaluate IAQ, key pollutants were measured indoors and outdoors during the week, and occupantsmore »« less

Balancing energy conservation and occupant needs in ventilation rate standards for Big Box stores and other commercial buildings in California. Issues related to the ASHRAE 62.1 Indoor Air Quality Procedure

Technical Report Mendell, Mark; Apte, Mike

This report considers the question of whether the California Energy Commission should incorporate the ASHRAE 62.1 ventilation standard into the Title 24 ventilation rate (VR) standards, thus allowing buildings to follow the Indoor Air Quality Procedure. This, in contrast to the current prescriptive standard, allows the option of using ventilation rate as one of several strategies, which might include source reduction and air cleaning, to meet specified targets of indoor air concentrations and occupant acceptability. The research findings reviewed in this report suggest that a revised approach to a ventilation standard for commercial buildings is necessary, because the current prescriptivemore »« less

Study of control strategy using outdoor air to reduce winter indoor humidity in Taiwanese apartments -- demonstrated by ventilation design for a bathroom

Conference Chao, N; Wang, W; Chiang, C; ...

Dampness in residential buildings is detrimental to the health of the occupants and causes the growth of mold and decay in the fabric of the building materials. In Taiwan the average winter relative humidity is 80% and the average temperature is 15 C (59 F). It has been found that the average winter indoor moisture content in Taiwanese apartments can be higher than the outdoor content by as much as 15%. Although the main cause for the increased indoor humidity levels has not been identified, removing the moisture generated from shower baths can help reduce the humidity. This study focusesmore »« less
