It can also help mitigate moisture buildup, reducing the risk of mold and mildew formation from cooking activities. Ventilation systems also play a key role in removing cooking odors — particularly in open-plan living spaces where kitchen smells can permeate into other areas — as well as expelling excess heat, contributing to a more comfortable environment.\u003c/p>\u003cp >There is no one-size-fits-all approach to air quality design in kitchens. Challenges, including costs, space constraints, balancing between functionality and aesthetics, noise levels, energy efficiency, sustainability, maintenance, user behavior, and diverse cooking styles, present hurdles in the design process. Addressing the challenges and potential solutions for IAQ and kitchen design requires a more comprehensive understanding, not just of IAQ but of occupant perception of IAQ too. \u003c/p>\u003ch2 >\u003cstrong >Occupant perception of IAQ\u003c/strong>\u003c/h2>\u003cp >A recent \u003ca href=\"https://www.sciencedirect.com/science/article/pii/S0360132323007400?via%3Dihub\">study\u003c/a> by the \u003ca href=\"https://www.welllivinglab.com/\">Well Living Lab\u003c/a> focused on reducing household pollutant emissions from cooking and cleaning. Researchers developed an automated IAQ control system that used real-time sensor readings for particulate matter (PM). They compared this automated system with a manual control setup in a study involving 14 participants in a simulated one-bedroom apartment. The automated system included a stove hood, portable air cleaners, and a bathroom exhaust controlled by set PM\u003csub >2.5 \u003c/sub>thresholds, while the manual control required participants to operate these interventions manually.\u003c/p>\u003cp >Surprisingly, despite lower PM\u003csub >2.5\u003c/sub> concentrations during cooking and cleaning in the automated system, participants' satisfaction, perception, and preferences regarding IAQ were similar in both setups. \u003c/p>\u003cp >The study found that participants tended to make IAQ complaints when PM\u003csub >2.5\u003c/sub> concentrations exceeded approximately 80 μg/m3 during cooking but made fewer complaints when concentrations were below 60 μg/m3. Although the automated system resulted in lower PM\u003csub >2.5\u003c/sub> concentrations during cleaning, participants didn't perceive the difference — likely because overall PM\u003csub >2.5\u003c/sub> concentrations during cleaning were already low. \u003c/p>\u003cp >These findings suggest a link between PM\u003csub >2.5\u003c/sub> concentration levels and participants' IAQ complaints, providing insights into possible thresholds for noticeable IAQ changes, which are higher than the World Health Organization’s (WHO’s) health-based recommendations. \u003c/p>\u003cp >For kitchen designers, builders, and developers, the study highlights the necessity of integrating measures to reduce cooking emissions. Industry professionals should prioritize functionality and user experience alongside aesthetics. While a visually appealing kitchen is essential, the true value lies in a design that contributes to a healthy living environment. Consider incorporating natural ventilation, ducted stove hoods, smart technologies, and higher efficiency air cleaning technologies to address the diverse challenges in optimizing air quality.\u003c/p>\u003cp >Homeowners want healthier homes, of which IAQ is a critical factor. \u003ca href=\"https://www.nber.org/digest/mar99/cleaner-air-results-higher-home-prices\">Studies\u003c/a> show healthier air and smart home upgrades can increase property value, and \u003ca href=\"https://www.bu.edu/bhr/2022/03/29/a-guide-to-developing-wellness-real-estate/\">homebuyers\u003c/a> are demonstrating a willingness to pay more for spaces that can improve their health and wellness. In fact, 81% of homeowners have indicated that improving IAQ was a primary focus for them.\u003c/p>\u003cp >The imperative for HVAC professionals is clear: Understanding and addressing the multifaceted challenges in kitchen ventilation is crucial for creating homes that prioritize both aesthetic appeal and the well-being of their occupants.\u003c/p>"},"type":"text","cl":"text p-_Js1xJSc"},{"key":"eLGYuZxmRwL","type":"section","children":["e9JMQvG7Q82"],"cl":"section"},{"key":"e4MkkyQlUtm","content":{"src":{"key":"pihWoZ_2mw","url":"https://cdn.vev.design/cdn-cgi/image/f=auto,q=82/private/KaxzywoIf0Rx41JdO6oEbX8EsUI3/image/pihWoZ_2mw.jpg","ratio":0.6666666666666666}},"type":"image","cl":"image"},{"key":"e0ZQ1YGiZbC","content":{"text":"\u003ch4 >\u003cstrong >Jovan Pantelic, Ph.D.\u003c/strong>\u003c/h4>\u003cp >Jovan Pantelic is a building scientist in the Well Living Lab.
