Energy Efficiency Projects: building fabric toolkit

  1. 1. Building FabricFrom Start to Finish: EnergyProjects Made Easy
  2. 2. How these guides workOur ‘Energy Projects Made Easy’ e-event is designed to provide you with tools and tipsto help you implement an energy efficiency project. Each of these guides focuses on adifferent type of project, and each is packed with hints, tips, links and case-studyinformation. These presentations are not designed to be detailed step by step toolkits;rather, they aim to provide guidance and inspiration for your future energy efficiencyprojects.Each guide follows a similar format:• an introduction to the topic• the types of improvements you can make• how to calculate the costs and benefits of your project – developing a businesscase for the project• tips and pointers towards suppliers and potential funding opportunitiesEnergy Projects Made Easy, Guide 2: Building FabricBlue case-study boxes are dotted throughout theseguides. All are from Alliance members who havesuccessfully implemented a variety of energy efficiencyprojects, and we’re delighted to be able to highlightsome of their work for your benefit in these guides.These red boxes contain usefulfacts and figuresThese green boxes link you to akey external resource
  3. 3. IntroductionThe fabric of a building refers to its walls, floors, ceilings, windows and doors.While obviously its energy efficiency is a crucial part of the design andplanning phase of a building, it’s also possible to make huge improvements onan existing building’s fabric.As well as the reduced energy costs, other benefit of implementing buildingfabric upgrades include complying with regulations, increasing your building’svalue and attractiveness and improving inhabitant productivity.Energy Projects Made Easy, Guide 2: Building FabricAround 10-15% of energy costs iswasted by heat losses through abuilding fabricWhile air conditioning and ventilation areaffected by the building fabric, heating is far andaway the largest energy cost implication.
  4. 4. OpportunitiesThis useful diagram from theCarbon Trust gives you abroad overview of the hugenumber of energy efficiencybuilding fabric projectsrelated to heating you couldundertake to improve theenvironmental performanceof your building.Energy Projects Made Easy, Guide 2: Building Fabric
  5. 5. Regulations and factors affecting performance• Building regulations now dictate that any building fabric refurbishmentmust improve the building’s energy efficiency is the work affects in anyway the thermal performance of the building.• A variety of factors influence the thermal performance of a building, fromthe general climate its situated in, its orientation, layout and form, the U-values of the building and thermal bridging.Energy Projects Made Easy, Guide 2: Building FabricU-values are the heat transfer properties ofmaterials: the lower the U-value, the betterthe material is at preventing heat loss. You caneasily obtain U-value information for thevarious elements of a building from suppliersor from trade associations. See the ‘fundingand suppliers’ slides of this guide for somecontact details.Thermal bridging is a processwhereby thermal insulation can berendered less efficient due topathways of lower thermalresistance. You can find out moreabout thermal bridging with thisguide from the Institute ofSustainability
  6. 6. Common Barriers and ConstraintsWesthill Communications are based in theCharlotte Street conservation area ofCamden, which limited their options whenthey were planning on upgrading theirwindow glazing.• If the building is listed or in a conservationarea, building fabric upgrades may be difficult, but notimpossible. You may have fewer options, butsuccessful building fabric upgrades can still beimplemented.• Occupation: it can be difficult to receive high levelsupport for a project when it involves as disruptive aprocess as installing floor insulation.• Is the building capable of structurally supporting theproject: some insulation systems can place a (literally)heavy burden on the building.Some building fabric options are moredisruptive in occupied properties thanothersEnergy Projects Made Easy, Guide 2: Building Fabric
  7. 7. Opportunities: roofs, lofts and ceilings• Loft insulation where none was previously installed is thesingle most cost effective way of improving the environmentalperformance of your building fabric.Up to 20% of heatin a building is lostthrough its roofEnergy Projects Made Easy, Guide 2: Building FabricWhile aimed more athousing, the Energy SavingTrust’s page on roof and loftinsulation has lots of usefulhints and tips• Recirculate warm air: so much heat in a building is lost through the roof becausewarm air rises. Installing ceiling circulation fans can redirect warm air downwardsto other parts of the building• In multi-story buildings insulation between floors can also help reduce verticaldisparities in heating. Suspended ceilings and insulated areas will also reduce thevolume of the building requiring heating• Thermal bridging is often a problem wheninsulating ceilings and roofs, as is the risk ofcondensation and freezing – proper ventilation isvery important
  8. 8. Opportunities: windowsRefurbishment opportunities:• Double and triple glazing• High performance and low emissivity glass• Solar shadingWesthill Communications installedsecondary glazing throughout theiroffices. As well as avoiding planningissues, this solution meant the office wasnot unduly affected by the work.As well as reducing their energy bills, thefirm has also benefitted from muchquieter working conditions, as previousstreet noise has been completely cut out.Energy Projects Made Easy, Guide 2: Building FabricThe Building Centre’s tripleglazing, combined with installing highperformance laminate glass, has reducedthe U-value (the measure of heat loss) ofits windows dramatically, from 6.5 to 0.8.Maintenance opportunities• Keep windows closed• Use curtains and blinds• Redirect sunlight using blindsSolar shading reduces glareand sunlight in thesummer, while allowingmaximum low-angledsunlight into a building inthe winter
  9. 9. Opportunities: walls and floors• There are a huge number of refurbishment options for walls andfloors, including heat reflective foil, internal wall insulation, cavitywall insulation, and even living green walls– Each of these options has varying costs and benefits. Heat reflective foilplaced behind radiators is highly cost effective, requires little initial outlayand can be installed simply without contractors. At the other end of thescale, a green wall obviously requires some fairly specialist installers!• As well as their being a huge number of general types of wall fabricrefurbishments, there are also many options within each type: forexample internal wall insulation can be achieved throughinsulation, plasterboard, mineral wool or composites. Your suppliercan suggest the best option for you.Energy Projects Made Easy, Guide 2: Building FabricA green wall such as in Camdenrestaurant and venue The Foundry hasheating and environmental benefits aswell as being a striking feature piece.The Building Centre improved the thermal envelope oftheir building with plasterboard insulation• Checking regularly for gaps, cracks and damp isvital maintenance for the walls and flooring of allbuildings
