Research study identifying the best performing, most energy-efficient and cost- effective techniques to provide controlled mechanical ventilation and humidity control in hot- humid climates with thermally efficient building envelopes.
Report describing ventilation system design, including a central fan integrated supply (CFIS) system, made up of a 6-inch outdoor air intake duct connected to the return side of the air handler with a fan cycling control to make sure the fan runs a programmed minimum amount of time.
This document covers a description of the need and applied solutions for supplemental dehumidification in warm-humid climates, especially for energy efficient homes where the sensible cooling load has been dramatically reduced.
Report describing concentrations of 54 volatile organic compounds (VOCs) and ventilation rates that were measured in four new manufactured houses over 2 - 9.5 months following installation and in seven new site built houses 1 - 2 months after completion.
Article discussing the risks that can occur from undercutting bedroom doors to provide return airflow from bedrooms, as well as corrective measures that can be taken to address these risks.
Report about field testing that characterizes the uniformity of room-to-room ventilation air distribution under various operating conditions by examining multi-zone tracer gas decay curves and calculating local age-of-air.
Guide describing how to install jump ducts in bedroom walls to balance air pressures between rooms, enabling constant air flow for conditioning and freshness even when room doors are closed.
Guide describing how to install transfer grilles in bedroom walls to balance air pressures between rooms and to enable stale air to return to a central heating system's air handler for reconditioning even when room doors are closed.
