Context: Drivers
and Legislation
Context: 80%
CO2 emission reduction + fuel security
Challenges: Buildings contribute 40% CO2 emissions CFPS only 30% efficient Waste (unutilised) heat from CFPS has capacity to heat every house in UK
Energy security and economic sustainability are key drivers for European competitiveness Plug load is greatest growing energy demand in buildings (Unregulated)
Context: Energy
Storage - Miller
RENEWABLE ENERGY STORAGE: Generation from renewables is now around 25% (UK), 40% (Scotland). Further capacity is needed to: •
Ease the tightening of capacity margins
•
Manage increasing peak demand and the intermittency of renewables
•
Meet renewables and emissions targets
•
Extend aging infrastructure and stem increasing costs.
Addressing these issues is essential to meet the trilemma of achieving affordability and reliability while decarbonising.
Context: Energy
Autarky
ENERGY AUTARKY: “the ability to meet energy demand through regional renewable sources of energy, saving energy, and using energy more efficiently (Abegg 2011)” •
applied at building, community and regional scales
•
employs technical solutions to optimise energy generation, energy storage and control technologies to achieve selfsufficiency
•
strategises planning based on renewable energy generation and low-carbon resource availability

Macro Micro Studio: Aims
AIMS:
•
to understand the efficacy of designing a gridtied, net-zero low-energy building using: • integrated carbon negative LZCGT’s; • medium-scale power storage; • energy management; • predictive controls;
•
to monitor physical and environmental performance of the building and understand user behaviour in relation to: • predictive weather data • energy consumption (regulated/unregulated);
•
to develop a formal, spatial and technical language for a net-zero low-energy building that responds to the high-value landscape context of the University Botanic Gardens.
Macro Micro Studio: Objectives
OBJECTIVES:
•
integrated technical platform to study interfaces between building, local micro-grid, and user;
•
smart bottom-up systems thinking for buildings that is driven by needs for warmth, cooling, power and convenience;
•
a low-embodied carbon construction system using regional resources, technologies and skills;
•
energy harvesting and storage using modular Liion batteries within the building footprint
•
sensor technologies to understanding user behaviour and relationships to building performance and technical systems;
•
intelligent user controls optimising system performance to reduce energy consumption
Macro Micro Studio:
Future Sustainable Energy-Self-Sufficient Communities
Energy Autarky principles potentially provide a catalyst for: •
Provision of equitable, low-carbon rural/urban communities:
•
Regional resource and bio-mass availability used as limits to sustainable development scale and determines community size
•
LZCGT’s combining generation, storage and intelligent controls optimised for scaled community energy systems
•
Contribution to regional energy requirements through renewable energy exports
•
Provides economic means for inward investment in local community infrastructure, rural employment and reduction in rural fuel poverty.
