Hybrid Thermal Mixing Ventilation Understanding PSBP What is the Priority School Building Programme? The Priority School Building Programme (PSBP) is a centrally managed programme set up to address the needs of the schools most in need of urgent repair. Following the release of the Facilities Output Specification for the Priority Schools Building Programme, Monodraught have utilised their extensive knowledge, product testing, and building simulation skills to develop low energy ventilation systems which meet the Facilities Output Specification requirements in a cost efficient manner. Through...

Why Choose Hybrid Thermal Mixing? Ideal Environment • The HTM is able to provide the ideal environment to school classrooms/ areas. • The HTM system is designed to provide mixed tempered air during winter, boosted levels of ventilation during summer and secure night time cooling. • The HTM system works in conjunction with natural ventilation provided by manual or automatic windows/louvres. • The HTM system can be used in single sided or cross flow ventilation strategies. Exceptionally Low Power Consumption • The HTM system has an exceptionally low specific fan power. • The HTM system comprises...

Placement within the Room Wiring Details The HTM units connect to a high level external volume control damper. A standard position for the units within each classroom is that the systems are mounted at the rear of the room furthest away from the teaching wall. Standard Connections Control Strategy Auxiliary Connections Power Supply The HTM incorporates a fully automatic control system based on a seasonal control strategy. The seasonal strategy is determined by time and date but is weather compensated to pick up unseasonal conditions. The All settings are customisable during commissioning system...

Additional Ventilation Monodraught’s HTM is designed to work with and control a range of VENTSAIR Façade Ventilation System (VAF). These systems typically comprise of an external aluminium louvre, a high specification volume control damper and an internal grille. The system can be specified to suit glazed frames or fitted with a flange to suit wall openings. HTM wall controllers are designed to be mounted within a zone and control up to 2 HTM units, in a primary and secondary arrangement. Two version of the HTM wall controller are available. Both wall controllers house a temperature and CO2 sensor...

Monodraught are the market leaders in providing natural ventilation, natural daylight, and low energy cooling solutions. HTM Building Simulation 2. Natural Ventilation Performance Within the IES-VE software, Monodraught has developed a performance model of the HTM, utilising the data that has been collected from component tests and on site monitoring, to produce an accurate representation for modelling. With a combination of the ModeIIT Building Modeller and MacroFlo Air Movement modules of IES‑VE, Monodraught can demonstrate the natural ventilation performance of the system within the modelled...

Hybrid Ventilation limits pre-heating of ventilation air and recovers heat from people and electrical equipment Facilities Output Specification (FOS) 2.6 Environment and Fabric 2.6.1. The Contractor shall ensure that external envelope and structure should be used to achieve the internal environment required based on a passive approach. The principles being for a passive approach to assist the achievement of the internal environment by: 2.8.16.3. In naturally ventilated spaces, the Contractor shall provide mixing of ventilation air with room air to avoid cold draughts in the occupied zone during...
