How can we create buildings that are resilient to energy disruptions and price spikes?
|
1) Use daylighting to reduce need for artificial lighting;
2) Operable windows for natural ventilation and some degree of passive cooling; 3) On-site energy production (photovoltaics, wind turbines, solar hot water heaters). |
|
|
Which of one the following represent the heart of green building assessment tools since it has the greatest influence on sustainability?
Water consumption, Energy consumption, Indoor air quality, Land use and ecology, All of these are equal importance |
Energy consumption
|
|
|

|
2008
|
|
|
According to the research by Treloar et al. (1999) which investigated the life-cycle energy consumption of typical office buildings, the energy consumed during initial construction amounts to roughly _____ of the total lifetime energy use. 1/4, 1/3, 1/2, 2/3, 3/4
|
1/3

|
What is Green Building?
|
Design & construction practices that significantly reduce or eliminate the negative impact of bldgs on the environment and occupants:
1) Sustainable site planning 2) Safeguarding water and water efficiency 3) Energy efficiency and renewable energy 4)Conservation of materials and resources 5) Indoor air quality |
|
|
Name seven principles of sustainable construction.
|
Reduce resource consumption (energy and mat'ls)
Reuse resources Use recyclable resources Protect nature Eliminate toxics Apply life-cycle costing Focus on quality |
|
|
In USA and NZ, about _______% of solid waste is from construction activity.

|
What is brownfield?
|
Abandoned, idled, or underused industrial/commercial facility where expansion or redevelopment is complicated by real or perceived environmental contamination
|
|
|
What is grayfield?
|
Bare or developed land within a blighted (economically depressed) area
|
|
|
Describe three general approaches to energy conservation in buildings.
|
1) Design building envelope highly resistant to conductive, convective and radiant heat transfer
2) Employ renewable energy resources 3) Fully implement passive design solutions; Involves building geometry, orientation, and mass to passively heat/cool itself |
|
|
What is the importance or purpose of certifying the level of ‘green’ in a green building?
|
1) Promotion of high-performance green building practices
2) Provides public statement about the building’s performance 3) Higher ratings tend to create higher market value due to prestige and lower operating costs |
|
|
How can the urban heat island effect be mitigated?
|
1) Install highly reflective and emissive roofs (reflect solar energy back to atmoshere)
2) Plant shade trees near buildings (reduce surface and ambient temperatures) |
