Analysis of sustainable or green construction costs and benefits

Since World Green Building Council is a non-profit organization that promotes sustainability in the design, green building and operation of buildings worldwide. It is part of a global movement of people from many different backgrounds, cultures, nationalities and industries (94 countries) whose commitment is not only the study of building ecological, clean and sustainable buildings, but also the investigation of sustainable cities and communities that conform a sustainable world.

In this case we want to present the report “The Business Case for Green Building: A Review of the Cost and Benefits for Developers, Investors and Occupants” whose translation we could define the how; “The Green Building Business Case: A Review of Costs and Benefits for Developers, Investors and Residents”

Research shows that there are a number of unquestionable benefits to developing green building projects that favor the various stakeholders during the life cycle of a building. Even so, one issue that continues to be controversial is whether it is possible to add financial value to the benefits of developing green buildings, which is a crucial fact for the real estate lender and investor community.

Design costs and sustainable construction:

What are the costs of construction? … Research shows that green buildings are not necessarily more expensive, especially if economic strategies, proper program management and environmental strategies are integrated into the development process from the outset.

While there may be an associated additional cost, compared to conventional building projects, the surcharge is usually not as high as you tend to think in the industry.

Value as an asset for sustainable construction

As investors and residents understand the importance of the environmental and social impacts of green buildings, the potential for commercialization of greener buildings increases.

Studies conducted around the world show that green buildings attract more tenants and boost lease and sale prices. In those markets where this type of buildings has become more common, the so-called “coffee discounts” have begun to appear, which point to buildings with less sustainable characteristics, which are finally leased or sold at a lower price.

Evidence compiled in the United States and Australia reveals that buildings rated under the Energy Star, LEED and Green Star certifications generally lead to additional rental prices between 0% 13 – 17.3% 14 , and a study shows a case of a discount In the lease of 9% .15 This reduction can be found in a study done in Australia, where the lower ratings NABERS (certification that only considers energy) often generate discounts on lease.

Operational costs in sustainable construction:

The green buildings have shown that you can save money by reducing the consumption of electricity and water and operating costs and lower long – term maintenance. The energy savings of these projects generally outweigh any additional cost of design and construction, and the investment recovers within a reasonably short period.

To achieve the projected utility, green high-performance construction must be backed by a powerful enablement or commissioning, affective management and continuous collaboration between owners and residents.

Productivity and health at work:

Studies indicate that ecological attributes in the design of buildings and interior environments can improve workers’ productivity, health and well-being, which translates into real benefits for companies.

Despite the evidence in relation to its positive impact, a higher quality of interior environments has not been prioritized in terms of design and construction, and its main cause remains the financial motives.

Although more studies are needed, it is clear that investing more in the interior can generate greater profits thanks to one of the main assets of all companies.

Reducing risks in green buildings:

Regulatory risks have become increasingly clear in many countries and cities around the world, with mandatory disclosures, building codes and laws prohibiting inefficient buildings among the most common.

Extreme climatic events and systematic changes in weather patterns affect the insurability of real estate and call into question the resilience of assets. Changing tenant preferences and investor risk assessments can translate into increased risk of obsolescence for inefficient buildings.

A point to emphasize are the methods and techniques of the green building that therefore entails to enter the bioclimatic world, from the article the construction of bioclimatic houses we can see 38 technical sheets that review the constructive methods of the work from the foundation to the cover.

We must take into account that the intensification of the concept of green buildings turn our districts and cities into greener spaces, we tend to prioritize large-scale economic initiatives, such as the fight against climate change, energy security, conservation of resources and creation Employment, long-term resistance and quality of life.

In addition, the present report is complemented by a small study on Green Buildings to Green Cities that implements examples of “case studies”.

Effective tips to reduce the  cost of building a green home

What strategies should we follow to adjust and reduce the cost of building our home?

We have summarized the 10 most important tips for building an eco-friendly eco house without sacrificing quality.

Contact the architect first

“Okay! It’s the first house I build and will probably be the last one since it’s a home for life, so I’m completely lost and I do not know where to start. ”

Many clients start by contacting the builder, this is a mistake as the builder does not Can do the architectural project and we will refer to his architect in turn with whom he probably has a commission agreed and who will absolutely be subordinated to the constructor since his work depends on him.

We need our architect to be independent and have no qualms about negotiating construction costs.

It is best to start by comparing architects, visiting two or three offices and comparing prices.

Define deadlines

Time is money, each month a work is delayed is an additional cost to the client either because he is paying a rent from another apartment or because he cannot sell his old house to move to the new one.

To negotiate from the outset the maximum deadlines for design and construction and to define economic penalties under a signed contract, in case of delay, is key to not having surprises, and is one of the most important points to reduce the cost of building an ecological house.

Requires a closed budget before you start

As they say “the paper endured everything” but once we started the work the changes are expensive.

Thus, we must demand from our architect a document of work items (measurements) detailed to the maximum so that the construction can be done by closed price without surprises in items that had not been taken into account.

Energy efficiency is a lifelong investment

You have to be careful when assessing costs, sometimes a larger investment will now be amortized in a few years and represents an energy saving forever.

The clear example is the insulation, saving us a little money now reducing centimeters of insulation is an energy expenditure of heating for ever more. You must always consider the cost of construction and the cost of maintenance to make the right decisions.

Builds in phases

If the budget is adjusted an ideal strategy is to leave elements such as fencing the plot or building a pool for a second phase that can be contemplated in the initial project but can be built after a few years.

Use local materials

In addition to being a way to save costs, building with local materials is more consistent and sustainable.

If we are going to use wood, there are options at local sawmills building with smaller sections and solid wood lightweight framing structures. If you use brick, there are good ecological alternatives of local origin such as Cannabis pressed hemp brick.

Participate actively in the project process

Participating actively in all meetings by understanding the proposals and making coherent decisions is the best way to take control of the project and its costs.

Letting yourself be advised by good professionals, ask questions and raise doubts continuously is going to be a key factor to be satisfied with the final result.

The options of building an eco-house are many and it is important to understand and participate in the decisions that are being taken. The best way to reduce the cost of building an ecological house is to keep informed of the evolution of the project throughout its development, to avoid possible confusion or unforeseen that delay the work.

Always ask for comparatives

It is logical but not always, from the selection of the architect, to the awarding of the work to the builder through the materials or the same geotechnical study of the land, it is important always to request comparatives of the budgets that allow us to value several options and adjust when necessary.

Reduce meters

Large houses are more expensive to build but also keep warm.

Think of flexibility of spaces

In relation to the previous point it is important to think of a house as a flexible space that throughout a life can be inhabited by a bachelor, a couple, a family with several children that when they become independent they leave again a couple of singles, etc. .

We must think of flexible spaces such as a study or reading room that is also a guest room and can be connected to a living room, an outside covered porch that in summer adds meters to our living room, etc.

Building a home for our family is a very important decision , where there will be many factors to take into account, of which in many cases we will not have much information. The best way to take these decisions and reduce construction costs is to be well informed of all the steps that we must follow from the beginning, and under the professional advice of an architect that fits our interests. Maintaining a constant dialogue with the team of architects and being well informed during the development of our project, is key to reduce costs and finish the work in the established deadlines.

Filling holes made by nails

Get rid of the loose edges. If after removing the nail protruding are some remains of panel, ráspalos carefully or push them out into the hole. Make sure the edge of the hole is flush with the rest of the wall so that no lumps or bumps after repairing the area.

Fill the hole with joint compound. Daubed with spatula joint compound and hand it over the hole to push the compound into it. Scrape the excess compound having the joint knife on the surface of the recess at an angle of 90 degrees to the wall.

  • Try not to stain the wall around the hole with joint compound as dry and paint miscarry cast them into the area. The joint knife smeared with the amount necessary to fill the gap compound.
  • If you stain the wall with joint compound around while you are filling the gap, clean it with a damp cloth.

Sanding filler. Once the component completely dry sandpaper thin passes the repaired area. Use a damp cloth to remove dust when finished. The surface of the wall where was the hole should now be smooth.

Apply a primer and paint the repaired area. For perfect repair without noticeable joints, use a soft cloth texture to give dab of primer on the repaired area. When dry, use another cloth to dab paint over the area.

What Is A Construction Change Order

Because most construction projects are carried out in tender and contract, the scope of work must be clearly defined before it begins. During the construction process, a variety of reasons can make plans change. A change order, a supplement to the existing contract, covers the cost and defines the procedure to suit the original planning.


Construction contracts come in many different types and styles, but most construction projects require a contract of some sort. These contracts, like any other, define the responsibility that each contracting party has with the other (s). The scope of work, time and cost are established in this legal document. Because of the complexity of many of the construction projects, it is more convenient than the scope of work, or the details of what the project entails, is clearly defined and agreed before starting work.


Usually, a customer who want to make a construction project invites several general contractors and / or construction managers for tendering for the work. The bidding process for construction projects requires utmost care and attention to detail, because, once the contract has been awarded and signed, it becomes binding on both parties. Bids must be an accurate reflection of the actual construction costs, and in order to so, the scope of work must be clearly defined.

Types of change order

The most common types of change orders made during the construction process is a change in scope (when a customer decides to add something to the existing work), unforeseen conditions (when a builder is a problem that was not predictable) and errors by professionals and omissions (when a builder says that plans and designs prepared by an architect or engineer does not accurately reflect the actual conditions or are somehow wrong way).


Because change orders only occur when there is a contract, they can be a real obstacle to the progress of the construction project. Although both sides have agreed in the original contract, they cannot agree on the necessary changes, which it has ruled that a change must be made, or how much will cost such changes. Some projects are carried out for months as the contract parties discuss these details. Change orders have the potential to be costly and difficult.

Expert view

Before construction begins, consider as far as possible, all potential obstacles to a construction project may face. Precise estimates of labor costs reflect these careful consideration. However, there are times when change orders cannot be avoided. When necessary, both parties must try to work together to solve the problem as quickly as possible and in a friendly manner. Much can be achieved in a spirit of compromise.

Making Construction Budgets

The construction budget is the process of calculating the cost of completing a project specific building. This process is carried out by computers, which can be used by companies or general construction firm’s subcontractors. Budgets are usually done as part of the bidding process, where each contractor sends its budget to the owner in hopes of winning the project.


  1. Reviews the plans, specifications and all project information. Examine each page prints with care to understand exactly what tasks are involved in the project. Look for any special equipment or facilities that may be added to the cost of labor.
  2. Create an offer sheet outlining all tasks to be carried out during the project. For example, a small renovation can include tasks like painting, demolition, carpentry and put soil. Larger jobs may include hundreds of different tasks. Many computers use the CSI Master Format system as a guide when developing an offer sheet. This system will minimize your chances of forgetting certain tasks.
  3. Decide whether you’ll need the prices of subcontractors. Examine your offer sheet to see what your company perform tasks and which will be contracted. Send drawings to subcontractor’s asking prices for these tasks. Give them enough time to prepare their offers or their budgets.
  4. Calculates the quantity and cost of materials required for each task. For example, measures the total square feet of gypsum board shown on the plans and multiply this figure by the average cost per square foot in your area. Repeat this process for each task on your bid sheet. For information on the average cost to help you with your budget you, refer to the book RS Means Cost Data Construction in the Resources section of this article.
  5. Determine the installation and costs of labor for each task on your bid sheet. For sheetrock, you multiply the total square footage for your average cost of labor per square foot. This cost calculated by dividing the hourly wage of your installers by the number of square feet that can be installed per hour. If each installs an average of 100 square feet (9.3 square meters) and charges $ 10 per hour, the cost of the installation is equal to 10/100 or US $ 0.10 per square foot (0.10 square meters).
  6. Add all your costs to get to your final budget. It includes labor, materials and subcontractor price. If there are any additional costs that you have not included, be sure to add too. This can include things like licenses, tools, equipment rental, supervision or overhead. Once you’ve reached your final budget, adds a percentage to cover benefits.

Tips & Warnings

  • Often, you can find guides updated construction costs in the reference section of your local library.

Learning To Estimate Construction Costs

Construction estimators used construction drawings, project specifications and the information obtained from visits to the site to estimate the cost of a job. The estimate that they contain all the material and hand of work associated with the construction and project management, as well as overhead costs, benefits and other charges.

The key to learning to develop estimates of construction is to develop an increasingly comprehensive understanding of the construction process. This allows the estimator to develop a thorough analysis of the project to develop an estimate as accurate as possible.


  1. Enroll in an accredited course. Engineering, Construction Management or Architecture can provide you a thorough understanding of the fundamentals of the construction industry. You will learn about the different materials used and how they are installed. In addition, you’ll get an idea of how buildings come together, and how different construction activities relate to each other. These courses include calculus classes and use of software estimation.
  2. Looking for a specialized course estimation. Many technological institutes of the community and technical colleges offer certification programs or individual courses that teach construction estimating. These courses can help you learn the basics of the construction process and also teach you to see the process with a critical eye.
  3. Acquires field experience through internships or training in the workplace. Many elements can affect an estimate and these elements may be different in each job. Spending time on the construction site is one of the best ways to become familiar with the various factors that may affect a project. Many large contractors hire students majoring in construction, both for internships and for jobs to choose to enter the company. These students usually start working at the site as assistant project manager and superintendent. You can get a true understanding of what it really takes to build a building or other project.
  4. Learn how to read blueprints. As estimator, most of the information you need for a project comes from its planes. In general, this ability can learn on your own with a little patience and practice. If you find it too difficult, it takes courses at your local technical institute or association of contractors. Develop good habits now plan review to help you when you go to develop the estimate of a job. This includes taking note of all the information in the plane, such as symbols and numbered notes. It is also important to look for discrepancies between the different sections of the planes, and clarify these points before submitting an estimate.
  5. Improve your understanding of the mechanical and electrical systems. These two elements usually make up most of an estimated construction costs and are also considered as the most complicated. The more you know about these elements, more likely you are to prepare an accurate estimate. Consider taking a course in basic electricity or HVAC systems. Read books on these subjects, especially those aimed at commercial systems. When looking for internships, think about taking a position with mechanical or electrical subcontractor. You’ll get invaluable knowledge that will be very beneficial for your career as an estimator and you may locate far ahead of other candidates when you begin to seek employment.
  6. Familiarize yourself with the Master Format system developed by the Construction Specifications Institute (CSI). This system is used throughout the construction industry as a way to organize construction activities, project specifications and other components. As an estimator, you will notice that most of your estimates are organized according to this system. Most software estimation are also organized according to the Master Format. They are 50 divisions in the system and each is divided into dozens of individual sections. For example, Division 22 is for plumbing, and Sections 22 01 to 22 20 containing various elements of plumbing materials and methods. Using this system helps an estimator to develop a comprehensive offering less omissions.
