for experience…

Our practice has grown over the past 40 years to become one of the leading Building Services Consultancies in Ireland and rapidly growing in the UK in all construction sectors including Education, Commercial, Industrial, Residential, Healthcare, Retail, Leisure and Public Buildings.

We value our clients and are a trusted partner for them, many of whom have grown with us. The repeat business of these clients since our establishment is something we pride our operations on and are very grateful for.

Our aim is a simple one of making our client’s businesses better. This we achieve not simply through excellence in engineering, but also through ensuring we are aligned with our clients’ project objectives. We have particular sustainability expertise delivering healthier buildings with superior energy performance thereby reducing running costs but more importantly increasing yield and asset values of buildings.

Lawler Sustainability was formed to provide an integrated approach to reducing clients energy consumption, carbon footprint and increasing sustainability. We offer consultancy and contracting services to clients’ in a wide range of industries looking to reduce energy costs, carbon emissions and develop energy strategies. We deliver this through a range of technical and practical services which have proven successful with our clients and showed many great benefits.

Our projects to date have achieved energy reductions ranging from 20% to 50%. In the past five years we have helped business owners save €10.2 million in energy costs and developed sustainable, energy efficient buildings. We have learned through experience how to adopt a holistic approach to potential reduction of energy, water and operational costs which in turn reduce the running costs of your building and create a ‘Sustainable’ reputation for your business.

We realize that no two sites are the same and our experienced staff will assess the best energy reduction scheme for your business and tailor a package to suit your exact needs. We also understand that not every business has the income to facilitate these projects. Lawler Sustainability can offer finance solutions for clients on energy projects which would allow projects to be completed that might not otherwise be possible.

Unlike many ‘new entrants’ to this sector we have almost 40 years experience designing, commissioning and monitoring the electrical and mechanical systems that are responsible for energy consumption within buildings. This in depth understanding of building systems means that we are uniquely positioned to reduce energy consumption. We offer a range of energy services including energy contracting, energy audits, energy rating services, renewable technology integration, carbon reduction programmes, bill analysis and energy procurement.


Building performance is not just about energy efficiency it also includes environmental sustainability and the wellbeing of the occupants within those buildings. Certainly a company’s sustainability agenda is becoming more significant as investors lean towards companies that have sustainability credentials. Our own experience shows companies that have a sustainability agenda by gaining certification in the BREEAM, LEED, WELL and EDGE rating systems for example are increasing their asset value and yields. We offer a range of sustainability services including support in the planning process, sustainability rating systems, optimising client budgets through advanced energy modelling, creating your carbon roadmap and CSR.

Building the Future of the Built Environment

The buildings of the future are set to be considerably different from present and past. Key participants in this change will be the Building Services and Sustainability Engineer. We have in recent years seen the pivotal role engineers play in designing buildings to optimise passively its environmental performance and carbon footprint.

The use of Building Information Modelling (BIM) will allow quicker and more efficient installation of services. Additionally with a strong emphasis on Health and Wellbeing, engineers and their systems will be delivering improved monitoring and better air quality. With the arrival of the Internet of Things there will be significant additional requirement for data transfer capability within buildings. Traditional Wi-Fi is unlikely to be able to support this and it is likely that we see use of light waves as a data transfer medium. This technology is set to form a crucial part of future building infrastructure. In addition to improved air-quality it will also assist with space planning, security, wayfinding and environmental control. We at Lawler Sustainability continue to track and deliver latest trends and innovations within our projects.
