Energy Efficiency Tests

Highly recommended. New research (Elmnurst Dec 2023) shows that around 70% of homes could have the wrong size of heat pump installed. The result can be higher purchase and running costs and poorer efficiency – the opposite of what is intended. Measuring the thermal performance of a property should be the first step in any consumer heat pump design reducing risk when making this investment.

Building performance testing is crucial for ensuring that buildings operate efficiently, provide a comfortable and healthy indoor environment, and meet regulatory requirements. It helps identify areas for improvement, optimise energy usage, and enhance occupant satisfaction and productivity. Finally, building performance testing will help you judge the effectiveness and value of any retrofit improvements you are planning; like heat pumps, insulation, ventilation etc.

Building performance testing can evaluate a range of  factors such as energy consumption, HVAC system efficiency, dampness, air leakage, insulation levels, indoor air quality, lighting quality, acoustics, and occupant comfort. It is advisable to have an individual consultation to understand your particular issues and circumstances.

Building performance testing involves a combination of on-site tests, inspections, data collection, measurements, simulations, and analysis using specialised equipment and software. Testing may include blower door tests, thermal imaging, heat loss measurements, air quality monitoring, and occupant surveys. Every property and circumstance is different so the testing programme and the reports will be tailored to your personal requirements.

Building performance testing is typically carried out by qualified professional such as building energy consultants, mechanical engineers, HVAC technicians, and environmental scientists with expertise in building science and testing protocols.

The frequency of building performance testing depends on factors such as building type, age, usage, and regulatory requirements. It's recommended to conduct testing during the design and construction phases and periodically thereafter, especially when renovations or retrofit projects are planned.

Building performance testing helps identify energy inefficiencies, indoor air quality issues, comfort problems, and potential health hazards. It enables informed decision-making, cost-effective improvements, compliance with standards, and optimisation of building performance over time.

Common issues identified through building performance testing include air leaks, inadequate insulation, inefficient HVAC systems, poor indoor air quality, damp and mould issues, uneven temperatures, excessive energy consumption, and inadequate ventilation.

The costs of building performance testing vary depending on the scope of testing, size of the building, complexity of systems, and location. Costs may include equipment rental, labour, data analysis, and reporting. However, the benefits of testing will almost always outweigh  the costs by optimising building performance, rightsizing retrofit products and reducing operational costs.

Yes, government agencies and industry organisations have established regulations, standards, and certification programs related to building performance testing, energy efficiency, indoor air quality, and environmental sustainability. Compliance with these standards may be required for building permits, certifications, or incentives.
