Why is building energy modelling important? Why should you care how it is done, who should do it, what are the cost benefits and impacts of getting this critical scope wrong?

Current Approach

A client tenders a project to a lead design consultant, in this scope energy modellking is necessary. The lead design consultant engages an engineering consultant who engages a sustainabiliyt consultant. Generlaly the sustainabiliyt consultat does the energy model.

The issue? They are not specialists in engineering, building systems, MEP: what hapens is you miss massive value in your supply chain by not having a qualified team drive the energy performacne of your asset.

The Benefits of Building Energy Modeling

Building energy modeling is an essential tool for architects, engineers, and building owners looking to optimize energy use, reduce costs, and enhance sustainability. As the demand for energy-efficient buildings grows, understanding the benefits of building energy modeling can significantly impact your project’s success and long-term viability.

What is Building Energy Modeling?

Building energy modeling (BEM) is the simulation of a building’s energy consumption, considering various factors such as climate, building materials, occupancy, and systems efficiency. This comprehensive analysis helps predict energy performance, identify potential improvements, and guide decision-making during the design and operation phases.

Key Benefits of Building Energy Modeling

1. Enhanced Energy Efficiency
One of the primary benefits of building energy modeling is the ability to optimize energy efficiency. By simulating different design scenarios, BEM allows you to identify the most energy-efficient options for heating, cooling, lighting, and ventilation. This leads to reduced energy consumption and lower utility bills.

2. Cost Savings
Investing in energy modeling upfront can result in significant cost savings over the building’s lifecycle. BEM helps pinpoint cost-effective energy-saving measures and ensures that resources are allocated efficiently. This proactive approach minimizes the need for costly retrofits and adjustments after construction.

3. Improved Building Performance
Building energy modeling provides insights into how various building components interact and affect overall performance. This holistic understanding enables you to design buildings that perform optimally under different conditions, enhancing comfort and productivity for occupants.

4. Sustainability and Green Certifications
Energy-efficient buildings are crucial for reducing carbon footprints and achieving sustainability goals. Building energy modeling supports the pursuit of green certifications such as LEED, BREEAM, and WELL. These certifications not only contribute to environmental preservation but also enhance the building’s marketability and value.

5. Regulatory Compliance
Many jurisdictions require compliance with energy codes and standards. Building energy modeling ensures that your project meets these regulations, avoiding potential legal and financial penalties. It also positions your building as a leader in energy efficiency and sustainability.

6. Informed Decision-Making
BEM provides detailed data and predictive analytics that inform decision-making throughout the building’s lifecycle. Whether it’s selecting materials, designing systems, or planning maintenance schedules, energy modeling offers evidence-based insights that drive smarter choices.

7. Risk Mitigation
By identifying potential energy performance issues early in the design phase, building energy modeling helps mitigate risks. This foresight allows for adjustments before construction, reducing the likelihood of performance shortfalls and ensuring that the building operates as intended.

How to Implement Building Energy Modeling

Implementing building energy modeling involves several key steps:

Define Objectives: Determine the specific goals of the energy modeling process, such as reducing energy consumption, achieving green certifications, or complying with regulations.

Gather Data: Collect detailed information about the building’s design, materials, systems, and occupancy patterns.

Select a Modeling Tool: Choose an appropriate BEM software that suits your project’s needs. Popular options include EnergyPlus, eQUEST, and IES VE.

Conduct Simulations: Run simulations under various scenarios to analyze energy performance and identify optimization opportunities.
Review and Implement: Evaluate the simulation results and implement the recommended energy-saving measures.

Conclusion

Building energy modeling is a powerful tool that offers numerous benefits, from enhanced energy efficiency and cost savings to improved building performance and sustainability. By integrating BEM into your project planning and design process, you can ensure that your building operates at peak efficiency, complies with regulations, and contributes to a sustainable future.

We went to the movies before the summer to watch Guardians of the Galaxy Vol 3. The end of a decent trilogy of movies, wrapped up with money made and everyone off to do other things.

On the way out of the cinema i noticed the poster for Fast and Furious X. Which I assume is a slightly less obvious way of writing ‘ten’.

I suppose if it is successful you keep making ‘em right? Maybe not.

I mean we could go deep into sequels, quality etc so best not – safe to say though that the best ever sequel was T2: Judgement Day. This is simply an incontrovertible fact of our life. And yes, they should not have made any more Terminator films.

What about the need for us to do more with less to meet sustainability goals? Is this not a massive problem for us since our very existence in this modern world seems to be tied to consumption.

Perhaps not, I don’t think we have to go without. Because if we do i am sure people will refuse.

I think we have to do more with less. Which if we actually examined how we use resource, items, and how we purchase it is surely very possible.

In fact how about how we waste our time, Chat GPT is shining an uncomfortable light on this aspect. Since a lot of the things we sit on our arse all day at work doing actually take ten minutes with the AI – what are we actually doing?

Each of us could easily be honest with ourselves and track what we do each day against the value it adds to our business or life, we will be surprised by the outcome. The point being we have so much waste in a lot of our systems that our societal direction could be changed simply by each of us examining this and talking about it. rather than sitting and doing the stuff all day which is of zero importance….

To reach net zero by 2050 we hear people tell us that we need to work on everything everywhere all at once. Do me a favour when someone says this to you and walk away.

No one in the history of time has been able to comprehend and respond to this type of narrative positively, It is a waste of a phrase and so alarmist it has the opposite effect of what i am sure it is designed to.

I run a lot, recent weeks have been upwards of 100km per week for week after week. And it is tough on the mind and tough on the body. Perhaps more is less with this type of activity? Actually no – I am replanning my time to assign more to one activity and less to another, perhaps the activity I am losing is doom scrolling on my phone.

We should seek to prioritise what we do against our goals. And our resource challenge, net zero challenge, and general move to a more sustainable existence needs us to think in this way.

This isn’t a story which needs us to never travel by aeroplane, to never drive a gasoline car, to never burn another hydrocarbon. It is a story that needs us to prioritise what we need to to with a view to our long term goal and vision.

We don’t need all those business flights – some meetings we can do remotely.

The shop is within a few km, walk instead of driving.

Need to fuel your buildings – make sure your buildings are operating efficiently so you don’t waste the hydrocarbon.

Even writing that we can burn hydrocarbons – in the full view of the total net zero narrative – has me in a state of fear. Is this not heresy?

I don’t think so, it is part of the transition and we know it is running out. It is criminal to think that our developed world can ban hydrocarbons while 2billion live in fuel poverty!

So, less is more. But less of the stuff we don’t need and more of the stuff we do need – as long as our decision making is framed against a long term goal of sustainability.

Personally, physically, mentally, and professionally.

The order never changes:

Reduce demand.

Improve efficiency of use.

Improve efficiency of delivery.

Make it renewable and sustainable.

These steps and a mindset shift move us forward in our goal. It is not everything everywhere, it is small meaningful steps and progress…
