Case Studies

Brookland's College, Surrey...

Brief: To retrofit insulated control Damper to existing Louvres glazed into window frames, with a decorative internal cover.

Design: An insulated one section Motorised Damper and decorative cover and internal grille and box suitably strengthened for a college classroom.

Didcott Girls School...

Brief: To design, model, manufacture and install, a Natural Ventilation solution for multiple classrooms with attenuation to prevent crosstalk between rooms.

Design: On a class occupancy of 34 we thermally modelled and designed a system with active wall units. Glazed into the windows to provide air to the rooms using displacement ventilation above door mounted passive terminals linked to multiple class rooms with integrated attenuation to handle. Crosstalk requirement, with a control system and weather station linked to the BMS system.

Keele University...

Brief: To supply and install High Level Atrium natural ventilation Louvres.

Design: 2 continuous Louvres incorporating 6 insulated Dampers, Spring Return Actuators for smoke vent and inverted internal Louvres.

Stamford School...

Brief: To supply insulated Louvres and passive stacks to ventilate a Lecture Theatre.

Design: An insulated one piece motorised Damper and internal Grille, for extract single bank passive roof terminal stack with insulated Damper and internal Egg crate Grille.

New HQ, Worcester...

Brief: The client required a Natural Ventilation system integrated with Motorised Solar Shading to provide a minimum energy use building.

Design: Calculation, selection, manufacture and installation of a bespoke natural ventilation system using wall units integrated into doors and windows, linked to passive roof terminal units including solar boost fans to enhance performance

Alban Middle School...

Brief: To provide high and low level insulated wall unit complete with attenuation for cross flow ventilation.

Design: An insulated one piece Motorised Damper complete with 50% free area Pod type Attenuator. A powder coated cover case was also used.

Medical Centre...

Brief: To provide a small window mounted natural ventilation unit with specific acoustic properties.

Design: Manufacture and test acoustically and have witnessed by the consultant a unit for use in multiple consultation rooms with individual room control set to each doctor’s preferences.

Kings School, Peterborough...

Brief: An attenuated wall unit set into a maximum depth of 320mm.

Design: A small format weather Louvre glazed into a Velfac window, with an in line attenuator and decorative internal Grille and full controls system.

Lakenham School, Norwich...

Brief: To design a manually operated wall system with powered extract to the corridor.

Design: A difficult concept to control the system manually through extensive factory and site testing. A maximum face velocity of 2m/second to provide 8 ltr per person a set of mechanical stops were fitted to limit travel and internal air scoops to catch and divert cold air onto the finned tube LST radiator to promote enhanced radiator performance and avoid drafts. Attenuated and thermally broken dampers to control air movement and noise levels.

Unity College...

Brief: To provide an attenuated wall unit with insulated damper louvre to be supplied by others.

Design: Site dimensions were taken and an acoustic box and damper were manufactured.

HQ, Worcester...

Brief: To design a terminal to architecturally enhance the building design.

Design: Alter the curb and roof detail to replicate the roof angles and provide removable panels to allow servicing from the roof.

Longsands...

Brief: A wall and passive terminal with structural curbs.

Design: Employing 3 D modelling and a structural engineer we designed a system including moulding the roof curbs to support and fit passive stacks on a split roof line and provide a sealed weather split level curb.

Didcott Girls School...

Brief: To design a passive cowl.

Design: Each passive terminal deals with 4 classrooms and is fitted with multi section insulated Dampers and Attenuators to stop crosstalk from 4 classrooms privacy.

Tennis Court, University of Warwick...

Brief: To design cross ventilation with additional passive roof terminal stacks with fan boost and attenuation.

Design: Computer model Stage 1 Cross ventilation, Stage 2 Wall inlet passive outlet, Stage 3 Wall inlet powered outlet, Stage 4 Passive and powered outlet all controlled via PIR detectors, COÇ temperature.

Naturalvent© can supply your stack with fan assist, in order to speed up the movement of air on still days or to aerate rooms with a large occupancy. Fans can be electrically or solar driven.

JCB World Parts Centre...

Brief: To naturally ventilate up to 200m3/second.

Design: Model and design a hybrid system with a cross sectional area of 180m2 active to provide a fan assisted dilution system for a major world manufacturing facility.
