The actual façade performance in Dubai is often different from what it ought to achieve, said Jason Pardesi, general manager, Wintech Middle East.

Pardesi was speaking at the ZAK World of Façades conference held on 20 March in Dubai. He stated that around 80% of all the energy produced in the UAE is consumed by buildings.

Over 400 participants at the conference listened to industry experts present the best façade solutions to reduce energy consumption in the Middle East, and to safeguard buildings from fire and smoke-related hazards.

He said that in Dubai, residential buildings consume more than commercial buildings.

The current building stock is inefficient with some buildings being thought to consume 220-360 kwh/m2/year.

The best practice in the UAE shows its most energy efficient buildings consuming 110-160 kwh/m2. The aim, as detailed at the Emirates Energy Efficient Summit 2016, is to reduce this to 40-60 kwh/m2/year.

Pardesi also highlighted that thermal engineering is of great importance in the UAE due to chances for fire blaze during summer.

Reducing or accounting for linear and point thermal bridging is an important part of the design process.

Balcony Linear thermal bridges can reduce heat by affecting the U-values by 9-18% which proves that thermal engineering and thermal bridging carries a great value in construction.

He stressed on the importance of air tightness in achieving desired envelope performance and the discomfort they can cause to the tenants if not monitored properly during construction.

As a solution, the construction process should be monitored effectively and in that case the cooling loads will be reduced by up to 8% for the worst buildings if the air tightness is controlled.

The conference focused on the new and emerging façade materials such as liquid glass and carbon fiber. 

Technal was the presenting sponsor of the one-day conference at Conrad Hotel, Dubai.
