Energy Efficiency

 

 

 

 

 

Waltham Forest in conjunction with Ascham Homes commissioned aerial photography specialists Blue Sky International Ltd to capture property heat loss information from dwellings within the London Borough of Waltham Forest.

 

The information was captured by flying an aircraft over Waltham Forest on the night of 26^th February 2008. You can use the site to access property information on how much heat is being lost from any dwelling in the borough.

 

The thermal image can be used widely across a council, enabling energy conservation officers, architects and general public quick and accurate analysis and reporting.

 

 

As part of the government’s Home Energy Conservation Act 1995, Local Authorities in the UK must increase domestic energy efficiency and decrease carbon emissions. Aerial infrared thermal imaging provides valuable data to analyse areas of thermal imagery overlaid onto aerial photography for comparison concern for heat loss activity.

 

Typically, the aircraft flies at a height of 2,000 feet and makes a series of overlapping passes over the area to be surveyed. The aircraft is fitted with satellite navigation equipment to prevent drifting. Aerial thermography can only be undertaken on a cold, clear, cloudless night during the winter months and at least two hours after sunset to minimise the effects of the daytime sunshine and to ensure that most properties are heated to a comfortable level.

 

This aerial survey is a snapshot taken at one moment in time to show how much heat your dwelling was losing when the aircraft flew over. The information provided is a guideline to the heat losses shown by colour scales (see below), but not the definitive guide to how energy efficient a property is, as the amount of heat a building loses can be influenced by many factors.

 

This scale represents how much heat loss occurred.

 

Very High illustrates that there was a significant heat loss on that night, this may be due to the fact that there is inadequate loft insulation and therefore heat is escaping at a very high rate OR it may be caused by a reflective surface such as a metal roof.

 

 

 

 

 

 

Very Low illustrates that there was minimal heat loss on this night, this may be caused by very efficient loft insulation or a lack of heating within the dwelling.

 

 

 

 

 

With some simple energy saving home improvements, you can save money, improve the comfort of your home and help fight climate change.

 

An energy efficient house makes economical sense as it's cheaper to run and it could be a key selling point if you choose to sell your house.
