  1. Barriers to Entry:Technology/Training • Thermal Performance • Lightweight versus Heavyweight • Insulation Materials • Wall thickness and U values & ££ • Air leakage • Window performance • Design for Zero Carbon • What is Zero Carbon? • Passive solar gain • Wind Turbines/Solar performance • Achieving airtight construction • Heating/Lighting/ventilation • Grid or battery? • MMC Skills Training • De-skilling construction • Multi-skills Eco-build • Accreditation: e.g. Airtight construction • New Machinery: Cranes • Cost/Benefit-Return on Investment • -Limited Government support • -Resistance from Developers • -Uncertainty of Estate Agents • -Paying for the unseen? • -What’s the target? Code? • Build Quality • -Poor quality actual build making • performance specs irrelevant • -Lack of Capacity to monitor quality • control • -Longevity of zero carbon housing

  2. Lightweight Construction • Towards Passivhaus Standards • Improved Insulation/ Thermal performance • Led lighting • Improved Window performance • Wood pellet Boilers • Solar Thermal • Rainwater Harvesting • Low energy MHRV • Micro-energy generation • Timber Frame-open web joists • Airtight Construction • MHRV • Minimal cold bridging • 20-35kWhr/m2/yr heat requirement • 1 air change per hour @ 50 pa • UK Design

  3. RuralZed Thermal Mass MMC • Glulam Frame • Concrete Thermal Mass • Rapid MMC • 5kWhr/m2/yr • Micro-energy generation • Led lighting • Wood pellet Boiler • 125yrs minimum life span
