Computational Fluid Dynamics (CFD)

Computational Fluid Dynamics (CFD) models detail airflow within a space and are an excellent tool for predicting HVAC performance.

Advanced Energy Modelling

There is an increasing demand from building users for safe, healthy, and efficient buildings which meet the needs of those who occupy them. This demand to demonstrate better building performance includes health and well-being as well as carbon, energy, and waste reduction.

Advanced Energy Modelling goes beyond building regulations to precisely detail the predicted end-use of each energy consumer within a building, across a year. This has significant value to the user and client by enabling building energy targets to be tracked against actual usage, highlighting the ‘performance gap’ and identifying opportunities for improvement.

Track Actual Usage and Identify Opportunities for Improvement

Computational Fluid Dynamics

One of the most effective methods of Advanced Energy Modelling is Computational Fluid Dynamics (CFD).

CFD uses applied mathematics, physics, and computational software to visualise how a gas or liquid flows – as well as how the gas or liquid affects objects it encounters.

Our sustainability team assesses critical aspects such as occupant comfort, air mixing, and air distribution for a vast range of spaces and buildings. This is particularly important in atria, swimming pools, auditoriums, sports halls, and other facilities where large groups of people congregate for extended periods of time. By helping to identify inequalities in the distribution of air around a building, CFD can highlight opportunities for improving HVAC efficiency as well as improving overall air quality.

Our Experience

HSE Primary Care Centres - Building Performance Optimisation

Lawler Sustainability was engaged by the HSE to complete a range of energy services at five HSE Primary Care Centres.

Given the nature of the five centres, they all had strict occupant requirements to encourage health and wellbeing. This included adhering to stringent daylight and natural ventilation requirements on all five sites.

Our in-house Computational Fluid Dynamics (CFD) experience allowed us to further demonstrate that these criteria were achieved, garnering A3 Building Energy Ratings (BERs) at all five centres.

Low Energy, Low Maintenance Design

Harvey Tucker, HSE Primary Care Centre

Lawler Sustainability and Lawler Consulting acted for us as Mechanical & Electrical consultants on the recent Primary Healthcare Centre in Shamrock Plaza, Carlow. We found that their service throughout all stages of the project was excellent. They understood the HSE briefing documents and represented us well in discussions with the HSE whose environmental requirements were initially ambiguous.

As landlord of the Primary Care Centre we placed particular importance on a low energy, low maintenance design. As engineers, they understood this brief and gave particular attention to this. They took the time to explain the life cycle approach to their design solutions. We were very pleased with the project management of the project and found a very practical approach to the delivery of the project derived from a wealth of experience in servicing commercial buildings. The building was completed on time without any budget overrun.

Based on this experience, we can highly recommend without hesitation Lawler Sustainability and Lawler Consulting to any party requiring a quality M&E consultancy service.
