Energy-Efficient Building Projects: A Step-by-Step Planning Guide

Estimates show that 90% of all the office buildings in developed cities around the world are already a decade old. What’s more interesting is that a staggering 80% of total office buildings will still remain in use in 2050.

Given the scenario, it makes sense to prioritize energy-efficient building projects over conventional ones. However, simple prioritizing without having a proper plan to realize this goal is not a smart move.

But don’t worry—this comprehensive energy-efficient construction guide is here to your rescue. Here, we will learn all that you need to know about energy-efficient construction, so let’s dive in!

Why Invest in Energy Efficient Building in the First Place?

Investing in an energy-efficient property with the right sustainable building planning comes with plenty of perks. These perks are the primary reasons why 73% of millennials are willing to pay for more sustainable real estate. That said, let’s take a better look at some of these primary reasons:

  • Lower Carbon Footprint: The main reason for prioritizing energy-efficient buildings is to reduce the need for fossil fuels. This helps you move to a clean energy source and also reduces the building’s carbon footprint.
  • Better Cost Saving: It is no secret that fossil fuel prices will only increase with time, but this is not much of a headache with energy-efficient buildings. Since these buildings consume much less energy than conventional ones, you can save a lot on costs.
  • Improved Air Quality: Energy-efficient structures have continuous ventilation to reduce reliance on HVAC systems. This reduces pollution levels within the boundaries of the building and thus encourages better health standards.
  • Asset Growth: Buildings that are energy-efficient do not consume energy and are thus much more affordable to maintain. Thus, selling this property at a future date will surely yield you a much better price for it.
  • Reducing the Use of HVAC Systems: Most conventional buildings rely on older HVAC systems that are not very efficient in most ways. An energy-efficient building gives you the opportunity to reduce your reliance on these systems. This will help not just save more on costs but also reduce the building’s carbon footprint.
  • Steps to Make a Building More Energy-Efficient

    Now that we better understand why investing in an energy-efficient is worth the cost, it is time to move on to the next part. In this section, we will explore the green construction step-by-step guide to help you get started on the right foot. These steps include the following:

    Step 1: Conduct a Building Audit

    The first thing that you must do is start with a comprehensive building audit to understand where you stand. You must evaluate every aspect of the building’s energy performance with the right data to make informed choices. Make sure to get insights on every detail, including energy use, carbon emissions, and occupancy rates.

    Step 2: Get an Idea of Occupational Data

    You must have a clear idea of how many people are living in the building or how many people are estimated to live there in the future. This occupational data will give you access to very valuable insights for optimizing the building’s energy use. This will help better manage all the lighting and HVAC systems to garner more efficiency from them.

    Step 3: Leverage Automation

    When it comes to devising a plan for constructing an energy-efficient building in today’s age, you must leverage automation. These days, a wide range of advanced technologies allow you to automate different systems. You can leverage this potential to automate the building’s lighting and HVAC for better efficiency. These systems will analyze the occupancy rate in a given room and optimize the lights and HVAC system accordingly.

    Step 4: Try to Create ESG Reports

    ESG stands for environmental, social, and governance, and these reports are important in enhancing a building’s energy efficiency. You must get these reports for your building or relevant reports from other buildings. This will help you track energy efficiency progress, leverage better insights, and use the right energy-saving building strategies.

    Step 5: Make the Most of Smart Technologies

    Once you have the insights from the ESG reports, it is time to use those insights to your advantage. This is where you can leverage smart technologies based on the building’s needs and boost overall energy efficiency. These solutions do an excellent job of monitoring energy consumption, identifying areas for improvement, and enhancing overall energy efficiency.

    Step 6: Reducing Reliance on HVAC Systems

    They contribute greatly to the building’s overall energy efficiency, and this is an area where you can save a lot of energy. The primary goal should be reducing the building’s reliance on these systems. You might be able to do that either with unique building designs or by using a more effective approach to ventilation or insulation. You can even leverage automation technologies to optimize the use of HVAC systems and enhance energy efficiency.

    Step 7: Optimize the Use of Natural Light

    There are many ways to do that, but updating the building’s design and structure to capture sunlight is very effective. This will reduce the building’s need for artificial light and go a long way in enhancing its overall efficiency.

    In Conclusion

    An eco-friendly building process is humanity’s answer to changing climate and increasing carbon in the atmosphere. It is very important that we leverage the right steps and strategies to keep things in check. So, ensure you are mindful of this information and use the right steps at the right time to get the best results.
