Crawlspace Ventilation Building code requirements for ventilation openings through foundation walls are intended to reduce moisture levels in the crawlspace. Section 1203.3 of the 2003 International Building Code sets forth the underfloor ventilation openings and cross ventilation requirements for enclosed crawlspaces, such as within stem wall foundations.

Crawlspace Ventilation Over the years, there has been considerable debate among the building science community about the use of crawlspace ventilation. NC Cooperative Extension's recommendation has long been that foundation vents are left fully open year round (with the exception of winter time when there is danger of freezing pipes).

U.S. Inspect - Professional Home Inspections: Crawlspaces - House Facts
Introduction A crawlspace is a shallow and uninhabitable area, usually between the soil and the first floor of the home. Crawlspaces usually provide access to the electrical, plumbing and heating, ventilation and air conditioning (HVAC) systems located below the first floor.

Hypothesis Studies have shown that airway pressure release ventilation increases cardiac output when compared with synchronized intermittent mandatory ventilation (SIMV). This occurs by allowing more spontaneous ventilation, which increases venous return. BiLevel ventilation is a form of augmented pressure ventilation that allows for spontaneous breathing at any moment of the ventilatory cycle. The purpose of this study is to determine whether BiLevel increases cardiac output when compared with SIMV. Method Patients on a ventilator with high peak airway pressures in an intensive care unit from December 2000 to November 2002 were studied. Patients with respiratory failure were initially managed with SIMV. If the peak airway pressure persistently remained greater than 40 cmH 2 O, patients were changed to BiLevel using a Puritan-Bennett 840 ventilator. Cardiac output measurements were made while on SIMV and after being converted to BiLevel. Results were compared using a paired Student t test. Results Thirty-six patients met criteria for the study.
Too often, attic ventilation is overlooked, not to mention ignored as a place for energy savings. That’s where Broan solutions make sense. Consider this: air trapped in your attic can easily reach 150˚ or more. With Broan ventilation solutions, it’s still a full 60˚ cooler in the attic on a 90˚ day. That’s why attic ventilation is critical to making any home more comfortable while lowering energy costs. Air-conditioners can run less and won’t have to work as hard. Humid, stagnant air can be removed, drawing fresh dry air across the surfaces. Your attic can be drier and cooler – the perfect tools to help fight potential moisture damage.
Comprehensive Whole-House Ventilation Strategy Most of us are familiar with the air quality index system that predicts outdoor air quality ranging from good to hazardous. The system warns those with respiratory problems to avoid outdoor exertion on bad days. However, the Environmental Protection Agency indicates that indoor air pollutants in office buildings, public areas and homes may be two to five times, and sometimes as much as 100 times, higher than outdoor levels. This is a special concern since most people spend 90 percent of their time indoors. Poor indoor ventilation at home can have an adverse impact on occupant health and comfort, especially for those that have greater sensitivity, such as children, the elderly and those with respiratory problems such as asthma. Inadequate ventilation can also increase the chance of moisture problems if humidity is not expelled from within, or if humid air from outside is drawn in without adequate conditioning. Manufactured homes are required to include ventilation systems capable of continuous operation, which is unique in the homebuilding industry. Most homes built on-site rely primarily on natural ventilation via leakage through the building envelope. In order to develop improved ventilation strategies for manufactured homes, MHRA has undertaken a course of research that will formulate a baseline for evaluating whole house ventilation and make common-sense recommendations based on solid scientific evidence. Needle in a Haystack The impact of airflow on building performance has traditionally been one of the most difficult phenomenons to quantify and predict.
