A trickle vent is a very small{{Quantify|date=August 2009}} opening in a window or other building envelope component to allow small amounts of ventilation in spaces intended to be naturally ventilated when major elements of the design—windows, doors, etc.—are otherwise closed.{{cite book |last1=Burdfield |first1=Martin |last2=Jones |first2=Stephen |last3=Redfern |first3=Stephen |last4=Fearn |first4=Colin |title=The City & Guilds Textbook: Site Carpentry & Architectural Joinery for the Level 3 Apprenticeship (6571), Level 3 Advanced Technical Diploma (7906) & Level 3 Diploma (6706) |date=16 March 2020 |publisher=Hodder Education |isbn=978-1-5104-5854-3 |language=en}}{{cite book |last1=Smith |first1=Melanie |last2=Gorse |first2=Christopher |title=Building Surveyor's Pocket Book |date=26 May 2021 |publisher=Routledge |isbn=978-1-351-39106-1 |page=352 |language=en}} Trickle vents are used extensively in Europe and are integrated into window frames to provide minimum ventilation requirements for naturally-ventilated spaces.
Energy efficiency ratings
The application of trickle vents in naturally-ventilated spaces can help contribute to IEQ Credit 2 under the LEED green building rating system. LEED EA Credit 2 references CIBSE Applications Manual 10, which provides advice on the design of naturally-ventilated spaces, recommending the installation of trickle vents in naturally-ventilated spaces. Within the UK, the application of trickle vents is required to meet the requirements of the Building Regulations; requirements are described in Guide F, Means of Ventilation.
Effect on indoor environment
Trickle vents will help avoid problems associated with poor ventilation in naturally-ventilated spaces, including reduced risk of condensation, avoided over-ventilation (minimizing energy consumption), and improved comfort through draft avoidance.
