Eco Hub at Lordship Recreation Ground, Haringey, London
Download
as PDF The new Eco-Hub is the centrepiece of the regeneration and transformation of the historic Lordship Recreation Ground, and has been designed to exemplary sustainable standards. Commissioned by Haringey Council and funded by the Heritage Lottery Fund Parks for People programme, Big Lottery and the Greater London Authority. It will provide teaching space for environmental education, a multi-purpose community space for community organisations including the Lordship Rec mother and toddler group, a public cafe near the playground and the lake, with kitchen and public WCs, and a boot room for Park volunteers. From the outset, detailed consultation with Friends of Lordship Rec, local user groups, environmental education teachers and officers at LB Haringey, helped develop a pragmatic building brief and set out the core aims of community involvement and a truly sustainable building design for the Eco-Hub. Local people joined the construction team to build the strawbale walls.

Design strategies
| Planned occupancy | Max. 50 people, 9 am to evening use. |
|---|---|
| Space heating strategy | Top-Up heating by hot water radiator. Heat recovery ventilation. |
| Water heating strategy | Gas condensing boiler. Remote electric heater. |
| Fuel strategy | Mains Gas. Mains electricity. |
| Renewable energy strategy | PV-136 13 sqm 0.816 kWp |
| Passive Solar strategy | Optimised windows facing South |
| Space cooling strategy | Natural cross ventilation. |
| Daylighting strategy | Multi-direction intake where possible. High level windows at Atrium. |
| Ventilation strategy | Natural ventilation and automated MVHR |
| Airtightness strategy | * Airtight membrane under roof structure sealed to inside of clay plaster on external strawbale wall. Clay plaster finished to provide continuous air barrier. * Suspended floor air barrier sealed direct to clay plaster on strawbale wall. |
| Strategy for minimising thermal bridges | Continuous insulation maintained throughout. |
| Modelling strategy | PHPP |
| Insulation strategy | * Raised Floor U-Value=0.10 W/(m2K)15mm Wood fibre bitumen impregnated insulation board + 360mm Cellulose fibre insulation between I-joists + 18mm OSB board + 50mm Woodfibre insulation butt + Solid Oak flooring * External Wall U-Value=0.11 W/(m2K) 30mm Internal clay plaster + 450mm strawbale + 30mm external lime render * Main flat roof U-Value=0.06 W/(m2K) 325-550mm Cellulose fibre insulation between I-joists / firrings +18mm OSB deck + vapour control layer + 160mm PIR insulation board + waterproof membrane + green roof sedum blanket |

Building services
| Occupancy | 50 people |
|---|---|
| Space heating | Gas boiler is Worcester Si30 GreenstarOptimum start time controls and a programmable main thermostat. there are 4 radiators, one in each main zone each with thermostatic radiator valves fitted. There is no weather compensation. |
| Hot water | Worcester Si30 Greenstar for main. Remote electric heater to 2 sinks in rooms. |
| Ventilation | 4 units of Drexel und Weiss Aerobusiness |
| Controls | Motion and humidity sensor - if the sensor detects moving, or humidity is high, the unit starts at Level 2. Humidity is lower than 30%, the unit slows down to level 1. No detection for 30 minutes - the unit stops. (Level 0) Every 2 hours the unit runs 15 minutes to enable the minimum needed air exhaust at Level 1. This function is active until next motion is detected. |
| Cooking | Gas cooker |
| Lighting | Lighting levels are as for a school, 300 lux generally with 500 lux in the office and kitchen. |
