Sean Keegan's presentation discusses ground source heat pumps (GSHP) as a sustainable building and design solution. GSHPs utilize the stable underground temperature of 11-13°C to provide heating through pipes buried horizontally in trenches or vertically in boreholes. The system transfers heat from the ground to a water tank via an electric pump and can provide both heating and hot water at lower costs than traditional systems. While initial installation costs are high, GSHPs reduce utility bills by 15-50% and provide efficient, environmentally-friendly heating well-suited for new, well-insulated homes with features like underfloor heating.

Julian Swindell

1. Air conditioning and ground/air source heating systems provide climate control beyond basic ventilation and heating by controlling temperature, humidity, air quality, and fresh/recycled air balance. 2. Air conditioning works by exploiting the physics that compressed fluids increase in temperature and expanded fluids decrease in temperature. Refrigerants are used in a closed loop system with compressors, cooling towers, and expansion valves to lower the air temperature. 3. While effective, air conditioning and heat pumps require significant energy to operate and their refrigerants have posed environmental problems, so high insulation and supplemental heating may provide a more cost effective solution for climate control.

Certification requires assessing current performance, developing improvement plans, implementing actions, and ongoing monitoring to enhance occupant satisfaction, retention, and financial outcomes.

Buildings are responsible for 40% of EU energy consumption and 36% of CO2 emissions. 75-90% of the existing building stock will still be standing in 2050, so improving energy efficiency is key to meeting EU energy and emissions targets. This document proposes a pan-European financing mechanism to incentivize households to retrofit buildings for energy efficiency through financial incentives linked to mortgages. This would support private investment in energy efficiency improvements estimated to be €100 billion per year, helping the EU meet its 2020 energy savings target.

The document discusses the benefits of green homes and mortgages, including lower costs, health benefits, and financial returns compared to traditional homes. It provides examples of green housing projects in Romania that have achieved certification. Government policies like property tax reductions for green buildings could further incentivize deep energy renovations. Moving forward, engagement is needed from mortgage underwriters, real estate appraisers, insurers and national banks to recognize the financial benefits of energy efficiency and lower total homeownership costs.
