The Benefits and Barriers of Building Green
Written by Kiara
“Going green” is one of the most laudable goals of our modern age; we must hit net zero emissions as quickly as possible. One way we can try to reach this goal is by building green.
There are a lot of different ways to build green, and a number of potential meanings behind the phrase “building green”. One take on “building green” is to mean “building in a manner which drastically reduces carbon consumption, and reduces greenhouse gases (GHGs) from the actual construction process, as compared to traditional building design”. Building green translates into, ultimately, building energy efficient buildings that save on financial costs while protecting the environment. The end product of a sustainable building project, the creation of a green building, is the primary focus of this article.
The benefits of building green
Reduced carbon emissions
The most obvious benefit of building green is that it reduces carbon emissions and other GHGs. Building operations and building materials contribute almost 40% of global CO2 emissions. If building operations were sustainably managed, with a low carbon footprint, we could make substantial progress toward averting a climate disaster.
Optimally, building construction would be done without carbon-intensive materials or carbon emissions from start to finish. The need for concrete, heavy machinery, and other carbon-intensive building materials and construction equipment in many construction projects, however, limits our ability to create completely sustainable building projects. Please see this article for ideas on how to reduce the carbon intensity of the actual process of constructing a green building.
The more readily attainable goal, other than projects with carbon-free construction operations, is the creation of green buildings themselves (which ideally generate enough renewable energy themselves to offset the carbon footprint of the construction operation). As such, we must set our lofty aims at creating building projects with low carbon footprints overall. These types of fully sustainable projects are ones in which the initial carbon cost of construction/ building operations is offset by renewable energy generation, energy efficiency technologies, and other sustainable strategies used in order to lower the carbon footprint of building projects.
One strategy to lower a building's carbon footprint is by using heavy insulation, coupled with ventilation, in order to drastically reduce (or totally eliminate) the need for traditional HVAC. Heating and cooling are the primary energy costs for buildings around the world.
Heat pumps (both electric and geothermal), as well as the other green building strategies found in this article, are ideal solutions to lower a building project's carbon footprint. Buildings should also be focused on the use of renewable energy sources, like solar, and geothermal when feasible. The use of energy efficient appliances, such as Energy Star appliances, can also substantially reduce a building's carbon footprint, lower energy bills, and create energy savings.
For more ideas on sustainable, energy efficient building operations and materials used in order to lower a building's carbon footprint, please see:
This is, by no means, just an imagined utopian dream. All new buildings can be designed to optimize the use of energy efficiency technologies and strategies. And even old buildings can be retrofitted with insulation, ventilation, heat pumps, and renewable energy sources in order to seriously limit (or even eliminate) their operational emissions.
Best of all, buildings with renewable energy assets can effectively reduce the carbon emissions of their neighbors (in certain circumstances where net metering laws have been passed. This can also be true of communities invested in community solar projects.). This is, in large part, because of green contributions to the electrical grid from their renewable sources - we’ll discuss this feature in more detail shortly.
If this seems utopian, remember: utopia means an imagined place in which everything is perfect. This is not a utopia in the traditional sense because it’s absolutely attainable. With appropriate incentives for sustainable building projects from governments and municipalities, we can live in a world like this.
Reduced overhead costs
Electricity, heating, and cooling are all very expensive. When buildings are heavily insulated, traditional heating and cooling methods can be replaced with novel sustainable technologies - heat and energy recovery ventilation, coupled with heat pumps, can drastically lower a building’s overhead costs.
When these sustainable technologies are integrated with renewable energy generation, large-scale operations can actually make money by selling electricity back to the grid. This, however, is dependent on the willingness of municipalities/ utilities to buy that energy (the need for net metering in order for property owners to sell excess renewable energy back to the utility) - barriers we’ll address in the next section.
A more reliable (and greener) electrical grid
Green buildings using renewables will often generate more electricity than they can use. When many buildings in a particular area use renewable energy themselves, the electrical grid becomes much more reliable. A diversity of energy sources is preferable - solar for days that are sunny, and geothermal generation for consistent reliability.
When coupled with power generation from the municipal grid (preferably from renewable sources rather than fossil fuel sources), there is a redundancy of energy sources in the community. This redundancy means that a failure in any one section of the grid is can be easily compensated for by a large amount of green, power-generating buildings.
The barriers to building green
Higher upfront costs
Reduced overhead costs, when coupled with appropriate mechanisms to pay for power generation, can more than make up for the extra costs associated with building green. But there’s no getting around it - the initial costs of building green are higher.
This is a problem that will slowly solve itself. As more businesses and homeowners opt to build green, demand for green building materials and technology will increase. This will increase the scale at which these technologies are manufactured, and newer, more cost-effective methods of building these technologies will be developed.
We’ve already seen evidence of this with solar panels, which are now the least expensive form of power generation on the planet. Demand soared, manufacturing soared, and now solar arrays are relatively inexpensive.
Of course, government incentives will be a huge boon when it comes to reducing upfront costs, and we hope that more governments will see the long-term value of green technologies.
Lack of knowledge
The second problem exists at both the commercial and residential levels - people simply don’t know that they can build green. While standards like Passivehouse and LEED have existed for decades, it’s rare to find someone who knows what these standards mean. If you don’t know that you can build green, you’ll default to traditional construction.
Part of the goal of this site, and the network of green activists around the planet, is to raise awareness of green practices. While sustainable practices, like recycling, have caught on worldwide, green building still remains largely misunderstood and underutilized globally. Governments, construction companies, green activists, and other stakeholders should be shouting about green buildings from the mountaintops.
Lack of consistent government/utility incentives
This is perhaps the biggest barrier to green building - a lack of unified political will. Incentives are spread unevenly across federal, regional, and municipal levels. As different political powers take office, financial incentives (i.e. tax credits, renewable energy subsidies, etc...) for sustainable technologies and renewable energy can change rapidly. Additionally, some incentives (rebates, retail discounts, etc...) are in the hands of private utilities and energy companies, whose whims can change as quickly as their boards of directors.
The lack of consistency in incentives is what Horst Rittel and Melvin M. Webber would call a “wicked problem” - there’s no obvious solution, and any attempt to solve the problem leads to new, equally complicated problems.
Our focus as activists, then, should be on informing the general public and businesses about the benefits of green building, and to inform politicians and utilities, continuously, about these same benefits. We must believe that the obvious incentives of building green speak for themselves and that our efforts to keep everyone informed will greatly help create a better, healthier life for all.
