Something to think about and some ideas that you could use next time you play simcity or make very important decisions about how the planets resources are used!
As a society we are dependent on our built environment and our natural environment. It is evident that the built environment has significant impacts on our natural environment and the health of our society. It therefore makes perfect sense to ensure that our built environment does not negatively affect the sustainability of our society and nature. The built environment is a significant contributor to Green House Gas (GHG) emissions and influences the manner in which we as a society utilize our resources. There is also proof that green buildings promote the health and productivity of the buildings’ inhabitants and uses.Consequently we need to ensure that our built environment reduces and minimized GHG emissions and also facilitates the sustainable use of our resources.
“… green buildings typically cost up to 5 percent more than standard buildings during construction, but can reduce waste output by 70 percent, water usage by 40 percent and energy usage by 30 to 50 percent.” (www.worldgbc.org)
Thus it makes perfect sense for all new buildings to be green. However, the concept of green building and the green building sector have been around for quite a while and don’t seem to have made much of an impact on the built environment landscape.
How many of the buildings that you use/ see every day may be categorized as green buildings that are contributing to the sustainability of the planet and society?
“Green buildings represent 2 percent of the commercial buildings and 0.3 percent of new homes in the US.” (http://www.scientificamerican.com/article.cfm?id=green-buildings-may-be-cheapest-way-to-slow-global-warming)
The concept of green buildings and the greening of the construction and building is a dynamic and evolving debate that covers (and brings together) a plethora of stakeholders, professions and topics. This in my opinion is the reason that the green building sector hasn’t moved beyond building certification, passing of (some) legislation and the development of a few green buildings that may or may not be facilitating the establishment of a sustainable society. It is evident that green building could in fact contribute to sustainable development; however, there are a few barriers that need to be overcome before the green building sector is able make a more sustainable development impact. The key issue in this regard relates to the skills and stakeholders involved.
In order for the green buildings sector to be able to make a more effective development impact and contribute successfully towards sustainable development the following should be considered;
- Fast tracking of the creation of an enabling environment. This includes policy frameworks, legislation and regulation through increased public sector involvement. This would create a demand for green buildings and greening technologies as well as create incentives and tax benefits.
- Broadening of the skills set in the construction sector and the use of multidisciplinary teamsthat do not only include the standard construction industry type of skills.
- The members of these teams need to be able to effectively work and communicate across professions.
- Team work, coordination and leadership skills are core skills in green building (www.uncsd2012.org)
- Increased awareness and capacity building initiatives that include non- construction sector stakeholders. This would;
- Ensure that people understand why it is important to build green buildings
- Show the public that there is another way of building
- Highlight the cost and health benefits of green buildings.
- Increase the demand for green buildings.
- The need to move away from an energy efficiency focus in green buildings towards a more sustainable development focus. There needs to be a more integrated approach that goes beyond energy, emissions, heating, cooling and solar panels etc Waste, transport costs, water and biodiversity should be integrated into the planning and build process.
- A move away from green buildings being seen as primarily large scale developments to a broader focus which includes green buildings within the residential sector. This would also have the effect of making green buildings accessible to a larger portion of the population.
- A move away from a tick box approach to green buildings towards an increased focus on the actual performance of the building.
- Green buildings need to be contextualized within a broader development and planning framework. Of particular importance is the need to focus less on individual green buildings and increase the focus on green developments which incorporate and integrate green buildings and green design.
- A green building that is inaccessible would negate the benefits of being green if it is associated with high travel costs and travel related GHG emissions.
- A green building that provides bicycle parking yet is located in area that is not conducive to bicycle use is a waste of bicycle parking space.
- Green buildings need to be integrated into the service provision and infrastructure needs of the surrounding environment. A green building that doesn’t contribute to the sustainability of the area that it is situated in is not really that sustainable or green.
- Green buildings could be used to provide services to the surrounding area. Examples are
- A building that generates excess electricity (solar, wind, biogas etc) that is then feed into the grid.
- A building that harvests rain water that can be used to water parks or gardens in proximity.
- Rooftop gardens that provide green spaces or act as green lungs in dense urban areas.
- Rooftop gardens that provide food to surrounding areas
