Case Study: The Ivy House

The Ivy House, London
(Subject of AIR Case Study)


The Ivy House is a welcoming, old country Freehouse located in the heart of the Chiltern Hills. It has signed up to the Hospitable Climates Programme, a voluntary energy efficiency standard designed to help the hospitality industry improve its bottom-line profits and customer experience.


The busy bar area is being extended and upgraded. Quality ventilation is required to remove smoke and odours to improve air quality and protect staff. As the building is Grade II listed it is very important that the system is in keeping with the existing design.


A supply and extract rectangular ducted system was fitted behind the bar area, concealing it from public view. Supply ‘eye ball diffusers’ and extract grilles were located around the upper fascia of the bar. The 'eye ball' diffusers are able to throw fresh air to all corners of the room while the extracts clear smoke, especially around the busy bar area. Ducting outwith the bar area was hidden by suspended ceiling.

A Sigma Heat Exchanger in the unit recycles the heat energy to maintain comfortable internal temperatures and avoid cold draughts.

Fresh air was also supplied behind the bar for staff. Total period of installation was 3 days.
