1Tralee Town Council Mitchels Boherbee Regeneration
2Mitchels Boherbee Regeneration Vision StatementEstablish an Energy Efficiency self sustaining area meeting the identified demand, transforming the local economy base through job creation and achieving a high living standard and excellent quality of life.
3HIGH QUALITY, ACCESSIBLE ACCOMMODATION FOR THE ELDERLY TOBAR NAOFAHIGH QUALITY, ACCESSIBLE ACCOMMODATION FOR THE ELDERLYIn November 2008, Tobar Naofa was completed as part of Phase One of the Regeneration ProjectConsists of 46 - Apartments and caretaker accommodation.Fully accessible and designed for independent living by the elderly.Secure Living : On-site resident caretaker, controlled access gate and private open space
5SUSTAINABILITYEconomic Sustainability in re-using a brown field site close to the town centre and achieving a density of 44 units per hectare.Social Sustainability- by providing a safe environment for elderly people to live independently within their community and with back up services at hand.Environmental Sustainability by reducing the energy demand of the residents and the use of a sustainable fuel.
6TOBAR NAOFA GREEN DEVELOPMENT Designed to SEI ‘House of Tomorrow’ standards i.e. 40% better insulated than the 2005 Building RegulationsAverage annual saving of 0.8 tonnes of CO2 / €200 per 2-bed apartment per yearRenewable resource- Wood Chip - fuelled District Heating System sourced locally
8Tobar Naofa, Block 5 Designed in compliance with 2008 Building Regs. 6 Units, 5 2-beds and 1 1-bedProject cost: €1.04 million (incl. vat)These units are to BER B1 standardSpecial features:Solar panelsPhotovoltaicRain water harvestingAir tightness (0.5 ac/hr)
9Heated with a Wood Chip fuelled District Heat System
11Wood Chip Conveyor and Store The Wood Chip is unloaded into the underground conveyor.The Chip is then transferred into the 80m³ Fuel Store.Unloading of a six ton delivery takes ½ hr. approx.
12Plant RoomTwo 500kW Hertz Wood Chip Boilers each with an auger feed system from the fuel store.The boilers which operate on duty/assist control are linked to two 5,000l thermal store buffer tanks.Distribution header with separate branch, pump and district heat pipe for each block of apartments and spare connections for future demand.
13Fuel Supply Annual Demand 1,130 ton Wood Chip < 25% moisture content3,400 MWhr Produced3.01 MWhr per tonDisplaces 300,000 litres of OilReduces CO2 levels by 900 tons8,230 kWh per Apartment€ per annum for heating and hot water.
14Heat MeterThe kWh heat output from the Boiler Plant is recorded on the Heat Meter.The Wood Chip Supplier records the reading at each delivery for billing purposes.The Supplier bills the Council on kwhs of heat produced.North Kerry Wood Chip, Knocknagashel, is the present fuel supplier.
15Grant SupportThe Biomass Boiler Plant was Grant funded by Sustainable Energy Ireland SEI under their Renewable Heat Deployment Programme.
16District Heating System District Heat Pipe Network to each apartment block providing temperature controlled space heating and instant hot water on demand at low cost.Supplying water at 700cthroughout the development
17Heat Distribution Substation Heat exchanger for instant hot water with anti-scald control.Underfloor heating manifolds with circulating pump and temperature limiting control.Time clock to control space heating times..Heat Meter measuring Kilowatt Hours.Pre-Payment Card System linked to an isolating valve.
18Underfloor HeatingEnergy efficient uniform heating throughout the apartment.Underfloor network designed to operate at low temperature 35ºC.Heat thermostatically controlled in each unitHeat store is built up gradually - no peak demands on Boiler Plant
19PAY AS YOU USE PREPAYMENT SYSTEM “Pay As You Use Pre Payment System” will provide the following benefits to the householderAddressing fuel povertyControl over their budgetNo bulk purchase of fuel requiredEnergy Awareness ToolHot water and heating on demandIncreased comfort level at reduced costThis prepayment system is already in use in 200 houses in Tralee and 60 in Killarney

22RETROFIT HOUSING STOCK To achieve a minimum Building Energy Rating of C1 for all housing units in the townPilot scheme, external insulation to 45no. UnitsThis pilot produced 30 jobs 14 weeksBuilding Energy Rating improved from G to CPotential savings € €1500 on heating and hot water cost per unit.Average insulation cost per unit is €9,540
23PAY AS YOU SAVE Retrofitting houses to a BER level of C1 Average cost per unit will range from €2,000 to €10,000Grants and tax relief are available for private houses with the balance being made up through the proposed Pay As You Save SchemeThis will be recouped from the potential savings of € €1500 on energy cost per unit per year, over 3 to 5 years

27Cunamh Energy ActionThe Cunamh Energy Action, Insulation Programme commenced in 1996 as a FAS C.E. Scheme to provide attic insulation, draught proofing and energy awareness advice.Supported by Tralee Town Council, Kerry County Council, NEKD and FAS.In 2000 the cavity wall insulation started - to address fuel povertyIn became a FAS Social Economy Project, employing 13 staff.In March 2003, secured a partnership contract with SEAI under the warmer homes scheme, with four insulation crews and 17 full time staff.
