Drones (UAVs) to Take Off in Energy Efficiency Audits of Buildings and Houses
/28th October 2016, RENEWABLE MARKET WATCHTM/ The building sector accounts for more than 41% of primary energy consumption in the US in 2015, contributing an increasing portion of the country’s carbon dioxide emissions reveals Renewable Market Watch™ in its report Drones in Building and Construction Inspection Global Market Outlook 2016÷2025. If energy efficiency rules and eco-design product standards were harmonised across the globe, the savings in energy and greenhouse gas emissions would be enormous, a new study has found. Up to 7,600 TWh of electricity would be saved by 2030 – a 13% reduction on the business as usual scenario. Global energy efficiency and eco-design measures could save the equivalent to almost double the annual electricity consumption of the United States making an estimated €280 - €410 billion in savings on energy spending, the study carried out for the European Commission says. At the same time, 4,450 Mt of carbon emissions would be avoided – equal to an estimated 7% of emissions in 2030. This would be the equivalent to the emissions of 1,170 coal-fired power stations, or more than the entire carbon emissions of the EU in 2012.

Today, energy efficiency standards are applied for at least one product by more than 70 countries in the world. Work to harmonize energy efficiency standards across the world is in its early stages. The EU has a very developed set of energy efficiency and eco-design rules covering a whole range of products from buildings to cookers. It has a target to make 20% in energy savings by 2020, rising to at least 27% by 2030.
With increases in energy demand and problems due to climate change, governments are increasingly focused on building efficiency retrofits and renovations. To help inform these improvements, energy audits are often performed with thermal cameras that can detect poor insulation and air leakage. However, the data collection process is labor intensive and does not offer a comprehensive view of the buildings.

With recent sensor improvements and falling costs, energy auditors are increasingly using drones (UAVs) with thermography—infrared (IR) cameras—to detect thermal defects and analyze building efficiency according to Drones in Building and Construction Inspection Global Market Outlook 2016÷2025. Research in automated thermography has grown commensurately, aimed at reducing manual labor and improving thermal models. Though promising, we could find no prior work exploring the professional auditor’s perspectives of thermography or reactions to emerging automation. Work in drones (UAV) automated thermography has also grown markedly in the past three years, encompassing disciplines from computer science and robotics to environmental and civil engineering. Researchers have primarily explored technical approaches for automatically transforming thermal images into higher fidelity 3D representations of buildings and houses and employing robots for data collection.

According to international normative standards the enhanced amount of old civil infrastructure and residential buildings has become an important issue regarding their energy consumption, their ageing process and hence life cycle management. Therefore important reason for high CO2 emissions is in many countries building age. Residential buildings, for example, constitute more than 85 % of all buildings in the USA and most of Europe, and they are on average over 50 years old. Most were constructed with energy inefficient designs and their materials suffer from degradation effects due to weather and wear, further impacting efficiency. To address these issues, renovations and retrofits of existing building stock has become a national priority in the growing number of countries.

Conventional means for monitoring the condition of those buildings and houses could not provide the information needed to perform detailed simulation in order to obtain accurate results regarding their thermal performance. Classic drones (UAVs) mainly provide integral information about cracking condition and possibly detachment of the covering layers of concrete or stone based structures, however, impulse IR thermography from unmanned aerial vehicle could provide more precise information regarding structural degradation on exterior layers and thermo-physical sampling. Furthermore, conducting impulse infrared (IR) investigation inspectors potentially could be able to estimate with accepted accuracy thermo-physical properties of building’s constructive material and hence we could be able to estimate the influence of ageing in thermal performance issues.
Therefore drones (UAV) based infrared thermography is a powerful technique for sub-surface examinations
Drone (UAV) systems are becoming attractive for many surveying applications in civil engineering as data acquisition platforms and as measurement instruments, to rapidly and autonomously acquire mobile three-dimensional (3D) mapping data. Therefore drones (UAV) based Infrared thermography is a powerful technique for sub-surface examinations according to Drones in Building and Construction Inspection Global Market Outlook 2016÷2025. Equipped with a remote controlled thermal camera, the drone monitors the structural health of selected areas by introducing a uniform heat-impact onto the examined area.
Use of drones (UAVs) in commercial sector is growing rapidly to provide aerial imaging solutions
Market observations of the research department of Renewable Market Watch™ show the use of drones (UAVs) in commercial sector is growing rapidly to provide aerial imaging solutions. Drones (UAVs) equipped with high-resolution thermal cameras provide an excellent investigative tool used for a multitude of building-specific applications and energy efficiency audits, including roof insulation inspection. They can graphically depict energy inefficiencies and identify wet insulations in the façade, roof or elsewhere by showing temperature variations within the building surveyed with great efficiency, which leads to decreased operational and maintain costs, shortened investigation span and improvement of other safety issues.
