What’s the best way to optimize building energy performance, life-cycle costs, and carbon emissions reductions?
While building owners and architects often rely on their mechanical engineers to address this question, a dedicated energy modeler can provide enhanced value when collaborating with the design team to optimize energy, costs, and carbon emissions.
The Value of Energy Modeling
A UAE developer was looking to deliver a ground breaking net zero project in Abu Dhabi and employed a consulting team who would be responsible for the energu performance and net zero calcualtions.
The consulting team relied on the mechanical engineer for energy compliance, since their scope already included code compliance and system design.
The engineering team decided to take a typical more steady state model approach using HAP software to identfy loads and evalue energy performance against the ASHRAE90.1 baseline to comply with the local Estidama code.
Howver, this process meant a lot of the systems were oversized since the approach did not take into account the actual peformacne of the buildig or allow analysis of the system response to changing building loads. Our modelling insight, as independent experts, meant we could support the engineer to design out inefficiencies and cut down on system sizes and capacities. This delvered significant capital savings for teh client in the region of $370,000 while ensuring code compliance ws maintained, alongsiide better performance and a higher likelihoodl of achieving net zero.
The Role of Mechanical Engineers vs. Energy Modelers
Mechanical engineers are crucial in designing and optimizing HVAC systems and other mechanical aspects of a building. Their primary focus is on functionality, minimum code compliance, and the overall performance of mechanical systems.
Energy modelers, on the other hand, specialize in whole-building energy modeling, using advanced software and analytical tools to simulate and evaluate a building’s energy consumption. They aim to optimize energy efficiency, find integrated opportunities for cost savings, and reduce the building’s environmental impact. Positioned adjacent to the traditional design team structure, energy modelers provide independent, unbiased evaluations, considering a wide range of options to determine the most effective solutions for a project.
Mechanical engineers are high value participants in any project and their skillset provides the following:
1. Valuable expertise in designing the mechanical systems of a building, including cooling, heating, ventilation, fire protection, water, and drainage.
2. Ensure that these critical systems are properly sized, integrated, and meet the owner’s project requirements and intent.
3. Focus on functionality, minimum code compliance, and the overall performance of the mechanical systems.
And the energy modeller skills dovetail into this critical component by:
4. Specialize in whole building energy modeling, utilizing advanced software and analytical tools to simulate and evaluate a building’s energy consumption.
5. Aim to optimize energy efficiency, find integrated opportunities for cost savings, and reduce the environmental impact of the building.
Benefits of a Dedicated Energy Modeler
Independence is key, and this is also recommended under the CIBSE TM54 framework which is an industry leading performance modelling standard. Having a specialist team overseeing energy and carbon scope means that designers can design, and get access to specialised information on loads, perfor,ance, conyrols, and emisison – at the riught time to enahnce project outcomes.
Consider the key scope in a build program. A complex undertaking with many consultants and designers. Why have a core component in this day and age – energu and carbon modelling – hidden as part of a sistainabilty consultant scope or down the supply chain in the engineering team.
This approach is sub optimal and impacts deliver on the design, engineering amd energy scopes.
Consider what the energy model team can focus on:
LEED Modelling.
Net Zero Modelling
International Future Living Institute Compliance
Code Compliance Modelling
Daylight Modelling
Thermal Comfort
Performance and analytics for controls systems.
All of these are specialist interests which, if covered with an independen modelling team, and help you ensure projects are delivered with optimal outcomes for clients.
This role is unbiased, meaning objecive analysis with a ‘best for project’ mindset – adding huge value for clients.
Plus with specialised expertise and advanced knowledge in whole-building energy modeling, energy modelers offer a unique perspective and identify opportunities that might be overlooked by other contributors.
This means engineers and designers get to focus on making sure systems and services are technically suited to the building performance requirements, are designed to the right spec, and that are functionally suitable for the building operation. The energy model team provides the details performance alcualtions needed to make the engineering designs work, and vice versa. It is a synergistic relationship and one which makes both roles work better and more efficiently.

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’.
Thanks for reading Running Zero! Subscribe for free to receive new posts and support my work.
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….
It takes a large group of us each making small changes which compound to have the greatest results…..
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…
