Services
Energy Assessments
Our Energy Performance Certificate assessments identify key areas for improvement in residential and commercial properties. Using SAP 2012 software, we provide detailed analysis of thermal efficiency and recommend cost-effective upgrades. Our assessments help property owners achieve better energy ratings and qualify for government grants.
Thermal Imaging Surveys
Thermal camera surveys detect hidden heat loss and moisture issues in building envelopes. This non-invasive technique identifies air leakage points and insulation gaps, enabling targeted remedial action. The survey forms part of our comprehensive building performance evaluation service.
Ventilation Solutions
We design mechanical ventilation systems that improve indoor air quality while maintaining energy efficiency. Our solutions address CO2 build-up and dampness issues in residential and commercial spaces. The systems reduce health risks and enhance occupant productivity through optimal air circulation.
Retrofit Design
Our retrofit designs integrate insulation, air sealing, and heating system upgrades to maximise energy savings. We create phased improvement plans with cost/benefit analysis for homeowners and property managers. Each design considers structural integrity and long-term maintenance requirements.
Renewable Energy Integration
Photovoltaic panel installations are tailored to property energy demands and roof capacity. We provide feasibility studies and system design for domestic and commercial applications. Our solutions include battery storage options and grid connection planning.

Questions
How can energy efficiency improve property value?
Energy-efficient upgrades typically increase property value by 5-10% while reducing running costs. Improved EPC ratings make properties more attractive to buyers and tenants.
What building types do you work with?
We specialise in residential properties including semi-detached houses, terraced homes, and apartment blocks. We also work on commercial and educational buildings.
Do you offer ventilation assessments?
Yes, we conduct indoor air quality assessments using CO2 monitoring and thermal imaging to identify ventilation issues and recommend appropriate solutions.
Can I get grants for energy upgrades?
Grants are available for boiler replacement and insulation works through the Housing Executive. We can advise on eligibility and application processes.
What's the payback period for solar panels?
Photovoltaic systems typically have an 8-year payback period with guaranteed returns for 20 years. Maintenance costs are minimal over the 25+ year lifespan.
How do you assess building heat loss?
We use thermal imaging cameras and blower door tests to identify heat loss areas. This helps prioritise insulation and air sealing improvements for maximum efficiency.
