Want to save money on your heating bills? Transition Malvern Hillsintroduces ENERGY TRACERS, Thermal Imaging Surveys.
Thermal imaging surveys by inspecting the inside of a warmed house and using a blower door, draughts and poor insulation can be seen.
A video with verbal report is left and advice is given on future actions together with installing an energy monitoring and action pack
"We are looking for "Hot Spotters" who will have this service for free provided they organise ideally 3 or 4 friends or neighbours within 10 miles travelling time to have their houses surveyed on the same day".
Householders pay £50 (ex VAT) each for a service worth hundreds of pounds. *In the Malvern AoNB we have been awarded grants so the service is FREE!*
For more information please contact Lynn Jones 07976 617645.

Environmental Preference Schedule Of Construction Elements, page 4
PLUMBING
- Polybutylene pipes (Hep2O) above ground and polyethylene below ground. Internal wastes in polypropylene or polyethylene
- Stainless steel
- copper
- PVC internal wastes and lead
Choice: 1 & 3. Principally Hep2O with occasional use of copper.
Reason: The copper was used in some places for aesthetic reasons.
TIMBER
- Reused where possible
- home-grown FSC certified
- imported certified
- pre-treated unsourced
Choice: 1, 2 & 3. A lot of timber was reused and we avoided the use of pre-treated timber.
Reason: In some cases it was not possible to identify a suitable alternative to imported timber.
HARD LANDSCAPING
- woodchip/bark or reused stone/brick/ concrete flags – no pointing
- concrete paviours made from recycled aggregate set in sand with no pointing, gravel
- new concrete or brick paviours with cement pointing, clay tiles
- tarmac
Choice: 1,2 & 3. We used on site crushed concrete for bases and a combination of local gravel, new and reclaimed paviours and minimal new concrete.
Reason: In some areas creating disabled access caused concern with gravel finish but using thin gravel over a binding mix in combination with the other materials has proved relatively successful in practice.
FENCING
- native broad leafed sp. or willow hedging
- timber fence/drystone wall or reused brick walls with lime mortar
- new brick/block wall
- concrete or treated timber
Choice: 2.
Reason: It was necessary to establish boundaries immediately for safety and security reasons, so hedging was not an option.
PRESERVATIVE TREATMENTS
- Avoid if unnecessary
- Local treatment with Borates where required
- Overall treatment
- Pre-treated timber
Choice: 2.
Reason: We wanted to ensure a clean build from a health and allergy perspective.
PAINT FINISHES/DECORATIONS
- untreated surface
- lime wash or water based mineral paints for walls and ceilings and wax and oil finishes
- Water based acrylic paints
- Paints with organic solvents and lead based etc
Choice: 2 & 3. All the oak and larch was oiled and the exterior softwood painted with Osmo microporous stain and internal wall painted with Auro paints.
Reason: Best preference to meet aesthetic and environmental preferences.
SEALANTS
- Coconut fibre, felt, sisal, lime
- Mineral wool, PE tape, EPDM seals
- Elastomeric sealant with base filler
- PUR foam, sealant or tape
Choice: Various were used including Lime, mineral wool, and Elastomeric. We avoided PU foam.
Reason: Practicalities.
LIGHTING
- Design for natural light with reflective surfaces
- Low energy and LED
- Low voltage halogen
- Tungsten
Choice: 1, 2 & 3. We used low voltage halogen outside for safety reasons.
Reason: artificial light essential for amenity, safety and security in winter.
HEATING
- Super insulated and designed such that no heating system required
- Carbon neutral heating system
- Condenser boiler
- Electrical heating
Choice: 2. Woodchip boiler with accumulator heat store.
Reason: Having the land, we wanted a system that could utilise home grown fuel and have planted willow for short term rotation coppice. It was not possible to achieve a zero heating option within the constraints imposed by the existing structures and planning permissions.
