What percentage of buildings are designed by architects?

Question

Current projects under construction, not all buildings ever built.

(Given that many buildings are designed by engineers, design-build contracting firms, or without the involvement of any design professional.)

Answer 1

Probably 95% in developed countries maybe 10% in developing nations.  In the US pretty mucha ll houses require plans drawn up by an architect.

Answer 2

Beyond energy conscious design

The potential threat of global climate change,

increasing energy demand of the developing

world, and inevitably, although not rapidly,

diminishing fossil fuel resources have made

sustainable energy supply a planetary issue

that has to be addressed by literally every

sector of human life. At the same time

buildings continue to play a significant role in

the global energy balance. Typically they

account for some 20-30% of the total primary

energy requirements of industrialized

countries. With increasing awareness of the

ecological consequences of energy

consumption, the need for energy and

environment conscious building design has

become more and more pressing.

The building designer already has a number

of sustainable technologies to choose from:

premium thermal insulation, advanced

heating, ventilation and air conditioning

(HVAC) equipment, passive solar

architecture featuring climate conscious

building orientation and advanced glazing and

daylighting options; active solar thermal

technologies for space heating and domestic

hot water; and energy efficient lighting and

appliances. All these measures can and

already have significantly reduced especially

the thermal energy requirements of buildings.

This in turn has increased the share of

electricity in the energy balance of the

building sector.

Until recently it was not feasible to go beyond

the energy conscious building design from

merely saving to actually producing high

value energy and sharing it with the whole

society.
