Stock Surveys

Project Info

Our client, a large local authority, had undertaken a refurbishment program of works across several decades. Several of the properties were now showing issues with high energy builds and in some cases internal mould growth. On paper the properties should have been performing far better as they had been cavity filled in the late 2000's and had been double glazed in 2010 with boiler improvements in 2014.  A fast low cost inspection program was required to determine the cause of the issues.

 

How IRT Surveys helped: 

SERVICES USED :

  • Thermal Imaging
  • SAP2012 Calculations
  • TheHouseSurvey.co.uk

OUTCOME :

On receipt of the clients stock list, IRT created an efficient survey plan allowing us to survey regions quickly and with minimum disruption. The front of every property was thermally imaged by our surveying team and the exact gps location and time/date logged automatically. Total survey time was 32 evenings/nights.

This data was then processed using our bespoke Envision software to determine regions of the property indicative of possible insulation defects. Envision builds 2 theoretical models of the property, one as if it were perfect and another with the identified defects in place. Energy use and CO2 output are determined for both models resulting in each anomaly being quantified for its impact on the building allowing every property to be ranked and rated.

Envision produces an As Built SAP and EPC rating along with an actual comparison, in addition to this Envision also runs a range of "what if" scenarios, such as Roof improvements, improved double glazing, boiler changes, and reports on the impact of each in terms of £s, kWh and CO2 saved per year.

This data was presented in an easy to use Excel spreadsheet with the thermal images embedded. The house survey.co.uk, our online property database was also provided as part f the package. This allows users to easily log on, search for properties, updated information, re-run calculations, map data and produce reports. (www.thehousesurvey.co.uk)

The House Survey

Project Info

Our client needed a way to engage with private homeowners, gather property information and provide funding solutions. Leaflet drops, door knocking and cold calling had provided good initial results but were now more of a nuisance to the homeowner than a benefit. 

 

How IRT Surveys helped: 

Services used :

  • Thermal Imaging
  • The House Survey Website

Outcome

IRT carried out a thermal imaging program of the front elevation of all 7000 properties in 10 days. Each property was assessed for heat loss and run through our envision software. This provided estimated SAP, EPC ratings and refurbishment savings. This data was uploaded to thehousesurvey.co.uk website and each homeowner sent a secure login code. This initial letter drop resulted in a 38% engagement whereby users could see the thermal image of their home and update property details. This data was automatically collated and mapped on the site allowing our client to see geographically the best and worst homes, who had engaged and how they were interested in improving their properties.

Project Info

Carrying out energy calculations and what-if scenarios can often be slow and expensive. Our client relied on external consultants and contractors to provide energy and saving calculations based on their products. This often lead to over ambitious savings being suggested to help justify a product sale. Our client was looking for an easy to use independent means of carrying out calculations quickly and easily.

 

How IRT Surveys helped: 

Services used :

  • Thermal Imaging
  • EDash

Outcome

IRT carried out an initial site survey and delivered a detailed thermal report identifying the current real performance of the property. In addition to this, the client also received a bespoke EDash login. EDash allows users to simulate retrofit measures by simply moving a slider and hitting calculate. Each calculation shows the impact on the EPC, £s, CO2 and kWh savings. Edash uses the SBEM calculation engine and a range of elastic templates to provide a close approximation to your property.
