CR19: Indoor Air Quality Design and Control in Low-Energy Residential Buildings - EBC Annex 68 | Subtask 4: Current challenges, selected case studies and innovative solutions covering indoor air quality, ventilation design and control in residences | 2020 | English | 135 pp
CR18: Ventilation and Indoor Air Quality in New California Homes with Gas Appliances and Mechanical Ventilation | 2019 | English | 364 pp
Substantial energy is used to condition the air that enters California homes through leaks in the building envelope and ductwork - typically about a third of all heating and cooling.
CR 17: Indoor Air Quality Design and Control in Low-energy Residential Buildings- Annex 68 | Subtask 1: Defining the metrics | In the search of indices to evaluate the Indoor Air Quality of low-energy residential buildings | 2017 | English | 116 pp
The objective of present work was to develop the metric that assess the performance of solutions securing high indoor air quality in low-energy (modern) residential buildings.
Because buildings are responsible for 40% of energy use and 36% of Greenhouse Gas (GHG) emissions in the EU, energy efficiency in buildings has become a priority to drastically reduce the energy use in buildings.
CR 15: Development and evaluation of a new test method for portable air cleaners | 2012 | English | 36 pp
The objective of this study was the development of a new test method for portable indoor air cleaners.
There exists a significant body of literature on energy and indoor air quality impacts of envelope leakage.
This study is about the effectiveness of the indicated ventilation measures in the day-to-day operations of three types of hospitality businesses:
Our lack of understanding of the health risks related to air pollutants exposure in buildings is perceived as a major deficiency, even though 80% of our time is spent indoors.
Air tightness is an important property of building envelopes. It is a key factor in determining infiltration and related wall-performance properties such as indoor air quality, maintainability and moisture balance.
CR 10: Ventilation Behavior and Household Characteristics in New California Houses | 2008 | English | 144 pp
A survey was conducted to determine occupant use of windows and mechanical ventilation devices; barriers that inhibit their use; satisfaction with indoor air quality (IAQ); and the relationship between these factors.
This report has been produced in the framework of the EU RESHYVENT project (Cluster Project on Demand Controlled Hybrid Ventilation in Residential Buildings with Specific Emphasis on the Integration of Renewables).
CR 08: Occupant behaviour and attitudes with respect to ventilation of dwellings | 2007 | English | 38 pp
This report has been produced in the framework of the EU RESHYVENT project (Cluster Project on Demand Controlled Hybrid Ventilation in Residential Buildings with Specific Emphasis on the Integration of Renewables).
This report has been produced in the framework of the EU RESHYVENT project (Cluster Project on Demand Controlled Hybrid Ventilation in Residential Buildings with Specific Emphasis on the Integration of Renewables).
Laboratory ventilation systems are designed to isolate and protect occupants from hazardous fumes and at the same time provide outside air at comfortable conditions.
CR 05: Considerations concerning costs and benefits with application to ventilation | 2007 | English | 54 pp
Decision makers that have to decide which type of HVAC system that has to be installed in a building, will usually base their decisions on the investment and running costs (including expected maintenance costs) and their perception of the quality
CR 04: Contrasting the capabilities of building energy performance simulation programs | 2006 | English | 68 pp
For the past 50 years, a wide variety of building energy simulation programs have been developed, enhanced, and are in use throughout the building energy community.
CR 03: Ventilated Double Skin Façades: Classification & illustration of facade concepts | 2005 | English | 49 pp
This document proposes a classification of the concepts of ventilated double facades, also referred to hereafter in this document as "VDF".
When an obstruction is present in a ventilation ductwork, the noise level may be considerably higher than the level measured without the obstruction.
Fans are used in many industrial, building and household applications, especially for ventilation, and are often considered as particularly noisy components.
