Module 6

Question 1

Why it is important the buildings design in energy?

Answer 1

• Cities are a whole should be planned and engineered to minimize energy consumption and to be enviromentally friendly. But also it is fundamental that authorities be worried about that individual buildings are implementing sustainable desings

Question 2

Exercy

Answer 2

• Energy consumption measure that takes into account the energy contained in the environment surronding the building to make the inside of the building better

Question 3

Residential energy demand?

Answer 3

• The greatest part is for cooling and heating
• Water heating 18%
• Space heating 45%
• Space cooling 9%
• Appliances 14%

Question 4

How much energy buildings consume worldwide?

Answer 4

Worldwide, buildings are responsible for about a third
of energy demand, two thirds of electricity production
only for their operation,

Question 5

Problems with aircondition

Answer 5

• Ugly
• They emit heat to outside of the building and make itself less efficient
• Solution inductive cooling towers that through heat up, not horizontal
• A good solution are cooling radiant panels
• The back of buildings are ugly and become underutilized

Question 6

Singapour project for air conditioned

Answer 6

• It is called 3for2
• Implementing LowEx technology allows to switch from air-based to water-based systems that drastically reduce the space in a building dedicated to energy transport.
• By using decentralized ventilation systems, this space requirement is further reduced.
• At the same time, LowEx technology increases system performance since supply temperatures can be reduced.
