Key Factors and Problems in the Performance of Kitchen Ventilation Systems Explorative Review Study
FACULTY OF ENGINEERING AND SUSTAINABLE DEVELOPMENT Department of Building Engineering, Energy Systems and Sustainability Science Key factors and problems in the performance of kitchen ventilation systems Explorative review study Álvaro Ros Hueda 2020 Student thesis, Advanced level (Master degree, one year), 15 HE Energy Systems Master Programme in Energy Systems Supervisor: Alan Kabanshi Assistant supervisor: Roland Forsberg Examiner: Magnus Mattsson ABSTRACT Regarding the great importance of a good working environment, in this research, ventilation systems installed in kitchens of restaurants were studied in order to avoid problems and to understand the key factors that can influence on the performance of the system. The results obtained were taken into account to provide some recommendations to a real ventilation system of a restaurant called Pastaria in Gävle (Sweden). This concrete ventilation system was not performing good, and some calculations based on the kitchen design were made trying to offset the problem. A large number of scientific studies related to restaurant kitchen hoods and ventilation systems were used to get the findings. These articles were obtained from scholar web databases. The main problem found in kitchen hoods is the inadequate exhaust airflow. The minimum required airflow varies depending on the size and shape of the hood. Keil et al. (2004) found in their research that only 39% and 24% of the studied hoods met the minimum recommended airflow from ACGIH and ASHRAE guidelines, respectively. Other key factors found are related to the kitchen design. The kitchen hood is recommended to have incorporated a capture hood covering all the burners. Side panels can be employed to increase the capture and containment. -

The project was undertaken between 2012 and 2014 by Newcastle University in partnership with Newcastle City Council and funded by English Heritage as part of a national programme of research. Part One of the report sets the Tyne & Wear HLC (T&WHLC) in its national context as one of the last urban based research projects in the English Heritage programme. It provides some background to the T&W region as well as the research aims and objectives since the projects inception in 2010. The report also discusses the characterisation methodology, data structure and the sources used. Part Two provides an analysis of the main findings of the project by summarising the urban and peri-urban, rural, and industrial landscapes that make up the T&W project area. -

Kitchen Ventilation and Indoor Air Quality Staff Slides
DOCKETED Docket Number: 19-BSTD-03 Project Title: 2022 Energy Code Pre-Rulemaking TN #: 235050 Document Title: Kitchen ventilation and indoor air quality staff slides This file contains the presentation given by Energy Commission Description: staff at the September 30, 2020 hearing and panel discussion on kitchen ventilation, indoor cooking, and indoor air quality. Filer: Peter Strait Organization: California Energy Commission Submitter Role: Commission Staff Submission Date: 10/6/2020 12:59:52 AM Docketed Date: 10/6/2020 Commissioner Hearing on Indoor Cooking, Ventilation, and Indoor Air Quality Pre-Rulemaking Hearing and Panel Discussion Presenters: Peter Strait, Supervisor, Standards Development Date: September 30, 2020 Background • Recent advances in the understanding of pollutants generated by indoor cooking, including research published by UCLA and by Lawrence Berkeley National Laboratory (LBNL), have called into question the sufficiency of existing kitchen ventilation standards. • Several public advocates, including the Sierra Club, have requested a hearing based on these studies and a summarizing paper published by the Rocky Mountain Institute. • A portion of LBNL’s research characterizing the capture efficiency of range hoods led to development of the ASTM E3087 test standard. The ASHRAE 62.2 Range Hood Working Group made recommendations for development of Home Ventilating Institute (HVI) rating procedures based on this new standard, resulting in HVI 917. 2 Problem Statement • Pollutants resulting from indoor cooking activities, including nitrogen oxides, carbon monoxide, and fine particulates, can reach levels that affect human health. • Minimum standards for kitchen ventilation, and specifically for kitchen range hoods, may not reduce the risk of exposure to harmful amounts of these pollutants to a sufficient degree.
