This is the Committee on Climate Change’s (CCC) tenth statutory Progress Report to Parliament – an important moment to reflect on the UK's achievements in tackling climate change to date. 2018 also marks the tenth year since the Climate Change Act came into force and, with it, the creation of the CCC as an independent statutory adviser.

Buildings are major consumers of energy for heating and cooling. The number of buildings is growing rapidly with demand for energy. To reduce consumption, governments worldwide have implemented codes, standards, and building practices.

Current and newly built buildings will inevitably experience the effects of climate change, therefore, the design and performance of these buildings should consider weather data that includes some of the effects of climate change, instead of only using historical weather data. However, climate change weather data suitable for buildings performance simulation are typically unavailable.

This paper focuses on the ex post evaluation of national energy efficiency policy mixes in the building sector, more specifically the effectiveness of implemented policy packages on helping to achieve energy savings and avoided greenhouse gas emissions (GHGs). The analysis covers all Policies and Measures (PaMs) affecting heating and cooling of residential buildings.

Emerging results from practice-based research demonstrate that energy efficient houses often do not meet theoretical energy use based on the current standards of residential buildings. A factor influencing this inconsistency is related to user behaviour and everyday practices. The objective of this research is to uncover some of the complexities associated with the practices of heating and cooling in the home, which are influenced by motivations, knowledge and technologies, including the use of photovoltaic panels.

A whole system approach was adopted to optimize a residential pool filtering system. This project presents for the first time, the experimental measurements of the pool water quality (i.e., the chemical concentrations) and all energy-consuming components when operating the filtering system at low flow conditions.

Highlights

  • Validated swimming pool and collector model, good agreement with experimental data.
  • Solar pool heating system performance optimized based on COP (energy ratio).
  • Optimized system achieves pump energy savings of approximately 60%.
  • System produces enough pressure to keep the vacuum relief valve closed.
  • Potential for 180 GWh of electricity & 150 kt of CO2 savings per year in Australia.

The present work investigates the feasibility of solar heating and cooling (SHC) absorption systems based on combining three types of LiBr-H2O absorption chillers (single-, double-, and triple-effect) with common solar thermal collectors available on the market. A single-effect chiller is coupled with evacuated tube collectors (ETCs) – SHC1. A double-effect chiller is integrated with parabolic trough collectors (PTCs), linear Fresnel micro-concentrating collectors (MCTs) and evacuated flat plate collectors (EFPCs) respectively – SHC2, SHC3, and SHC4.

This paper presents energetic, economic, and environmental (3E) analyses of four configurations of solar heating and cooling (SHC) systems based on coupling evacuated tube collectors with a single-effect LiBre-H2O absorption chiller. In the first configuration (SHC1), a gas-fired heater is used as the back-up system, while a mechanical compression chiller is employed as the auxiliary cooling system in the second configuration (SHC2). The capacity of the absorption chiller is designed based on the maximum building cooling load in these configurations.
