Algiers Village Living Communities Challenge Vision Plan

Recommendations

Info

ENERGY The intent of the Energy Petal is to signal a new age of planning, wherein a proposed Community relies solely on renewable forms of energy and operates year-round in a pollution-free manner. In addition, it aims to prioritize reductions and optimization before technological solutions are applied to eliminate wasteful spending—of energy, resources, and dollars. The majority of energy generated today is from highly unsustainable sources, including coal, gas, oil and nuclear power. Large-scale hydro, while inherently cleaner, results in widespread damage to ecosystems. Burning wood, trash or pellets releases particulates and carbon dioxide (CO2) into the atmosphere and often strains local supplies of sustainably harvested biomass. The effects of these energy sources on regional and planetary health are becoming increasingly evident through climate change, the most worrisome major global trend attributed to human activity. Imperatives 06. NET POSITIVE ENERGY 5. NET POSITIVE ENERGY LCC CRITERIA: 105% of the Community’s energy needs must be supplied by Community-generated renewable energy on a net annual basis, including all energy for water and waste conveyance. Use of combustion-based energy supply is not allowed. A Community must provide local energy storage for resiliency. Algiers Village Vision Plan 6.

ANALYSIS Currently, over 75% of energy consumed in VT is from fossil fuels, used primarily for heating and transportation. Because none of these fuels are sourced within the state, the money spent on these fuels contributes little to the local economy. Vermont as a state has expressed the goal of meeting 90% of its energy needs with renewable sources of energy by 2050. Algiers Village could serve as a shining example of how a whole community can achieve that goal and more, by becoming a net-positive energy community. Certainly part of this future will be a more distributed grid powered by renewable energy sources. The following feasibility analysis assesses the potential for Algiers to be completely powered by solar photovoltaics (and with the necessary energy efficiency measures). NET POSITIVE ENERGY FEASIBILITY STUDY 2,000 MWh of solar energy 1,500 1,000 500 Baseline Energy Use Optimized Energy Use (75% efficiency gain) Solar Rooftop Harvest Potential Existing Array Potential Baseline Energy Use: Estimated electrical and thermal energy consumption for Algiers (18 buildings closest to town center) based on averages by building type. The data was calculated using town-specific energy data that the Windham Regional Commission compiled for Guilford as a part of Act 174 Planning . Optimized Energy Use: Reduced consumption representing a 75% reduction in energy use, which is a level commonly seen on Living Building Challenge Buildings. This level of efficiency could be gained by requiring new construction to meet strict EUI standards and performing deep energy retrofits on the existing building stock. Solar Rooftop Harvest Potential: The amount of energy that can be harvested by installing current PV technology on all available roof area with appropriate orientation as identified using NREL’s PV Watt Calculator. Existing Array Potential: The assumed production potential of existing PV arrays in Algiers as identified by the Renewable Energy Atlas of Vermont. Analysis: This analysis shows that net-positive energy utilizing only rooftop solar installations is feasible with extensive deep energy retrofits. POTENTIAL FOR MODERN WOOD HEAT The Algiers Village team recognizes that the Living Community Challenge does not currently allow for combustionbased energy supplies. However, Algiers would like to work with the International Living Future Institute to explore
