Time-averaged Single Sided Ventilation Rates and Thermal Environment in Cooling Mode for a Low Energy Retrofit Envelope

Submitted by on Tue, 08/19/2014 - 10:31

Non-invasive, scalable, building retrofit solutions are very attractive deep renovation techniques to improve energy efficiency in existing buildings; this includes natural ventilation for cooling due to the low impact nature of the installation. However, a number of criteria that are important to natural ventilative cooling strategies can be substantially altered as a result of an external retrofit solution.

Non-invasive, scalable, building retrofit solutions are amongst the most likely large scale adoption techniques to assist in climate change adaptation in the existing built environment, particularly in university type buildings where rehousing live activities will prove costly. Natural ventilation is an attractive retrofit strategy due to the low impact nature of the installation. A number of internal environmental criteria that are important to ventilative cooling strategies can be substantially modified as a result of an external retrofit solution.
