TECHNOLOGY INTELLIGENT BUILDINGS
The Cybertecture Egg by James Law Cybertecture planned for Mumbai
Commercial organisations can encourage their staff to be more aware of green measures by offering green bonus schemes
and the occupants. Not only this, but they will also impact on the way we deal with heating, ventilating and air conditioning, because they give rise to a new generation of energy- producing buildings. The occupants of buildings often say they
have little control over their environment. There is currently a debate about the need for personal carbon footprints, plus a growing trend towards respecting the needs and responsibilities of the individuals who occupy buildings. The emergence of sensors that can be embedded into clothing, materials and equipment, together with wireless sensor
Friendly bacteria
We have tended to think of bacteria in a negative sense, but now there is much research showing applications using the chemistry of bacteria, such as the microbial fuel cell for generating electricity being researched at the Netherlands Institute of Ecology.
Algae is another exciting area. The BIQ apartment complex in Hamburg was completed in May 2013 and generates heat from its dynamic façade, which has – on the southern aspects – bioreactors in the form of transparent

glass containers that create a controlled environment for photosynthesis to take place and algae to grow aided by liquid nutrients, carbon dioxide and pressurised air. Part of the light not used for photosynthesis is converted into heat, so the containers double as solar collectors. The algae is collected periodically and fermented to produce methane, which can generate electricity. Firms such as US-based Grow Energy is marketing this Verde algae system for mounting on walls or roofs.
networks, will result in a ubiquitous network providing extensive and valuable real-time data on performance. The captured data on occupants’ responses
to the changing environment can be analysed to reveal significant patterns that can be used to provide a degree of personal control. This will become normal practice over the next few years. Wearable electronics in clothing and personal accessories are already highly developed in the textile industry, and will help people to become more aware of the impact their actions on energy and water consumption, for example. Smart metering in buildings will help us
to understand the influence of occupancy behaviour on consumption levels, and guide people to ways in which they can reduce these levels and become more sustainable. The benefit to the domestic consumer is that they can save money and, in the case of commercial buildings, organisations can encourage their staff to be aware of green measures by offering green bonus schemes. Also, by comparing the performance of the building and its systems with the responses of the occupants, one can easily define areas of dissatisfaction and see if more appropriate design criteria may be used. It is already
