FUNCTIONS OF A FACADE

INTELLIGENT FACADE

• Buildings able to adapt to changing climatic conditions are calledintelligent buildings. Adaptation means that buildings and façadesadapt to current weather conditions.

• Instead of shutting the environment out, it makes more sense to makeuse of it since this will have a positive impact on the comfort level ofthe occupants as well as on the energy consumption.

• Adaptive façade helps to minimise at least some of the disadvantagesso that a high comfort level can usually be achieved even without air-conditioning. In so-called hybrid buildings the comfort level can befurther increased by integrating a supporting air-conditioning systemfor extreme climatic conditions.

INTELLIGENT FACADE

• An intelligent building envelope adapts itself to its environment bymeans of perception, reasoning and action. This innate adaptivenessenables an intelligent building envelope to cope with new situationsand solve problems that arise in its interaction with the environment.

WHY INVEST IN FACADES

• India is the world’s fourth largest energy consumer (EIA, 2013) andfifth largest source of greenhouse gas emissions (GOI, 2010). With thebuilding sector contributing 35% of the total electricity consumption(Rawal et al, 2012), and a projected five-fold growth in theconstructed area anticipated by 2030 - from a 21 billion square feet in2005 to 104 billion square feet, building energy efficiency plays amajor role in managing energy use in India (Seth, 2010).

WHY INVEST IN FACADES

• India’s national Energy Conservation Building Code (ECBC, 2008)was revised in 2008, but remains voluntary and has not been adoptedby most of the Indian states. To encourage adoption of ECBC, a three-tier approach has been proposed which advocates implementation ofthe ECBC codes in phases, and allows time for training and capacitybuilding (Rawal et al., 2012).

• Tiers are categorized based on: ease of implementation within currentpractice, the energy savings potential, and the ROI offered. Tier onefocuses on envelope-related measures, tier two on HVAC, while thethird tier regulates lighting measures.

INTELLIGENCE IN ARCHITECTURE

The intelligent features in a façade require integration of responsive dynamiccapabilities, which allow for changes in the façade’s configuration based ondaily and seasonal stimuli, and considering the surrounding environmentalcontext in order to reduce the energy consumption and increase the buildingefficiency.

Developing buildings with intelligent features should achieve betterperformance by implementing the following processes:

a) Creation of a relationship between the occupants’ behaviour and indoorspace condition.

b) Provision of automatic adjustments in response to environmental changesand occupant’s requirements.

c) Generation cost-effective modifications based on changes on tasks andusers behaviour.

The process of the adaptive feature and data flow through the

intelligent façade.

The operation of intelligent buildings should be treated as if they

possess smart features and some cognitive abilities that allow them

to perceive data, analyse it, and respond with an appropriate reaction
