Building-integrated carbon capturing is a system that provides carbon dioxide (CO2) capture and regeneration within buildings using a moisture-swing air capture technology developed by Dr. Klaus Lackner at Arizona State University’s Centre for Negative Carbon Emissions. This paper serves as a continual ideation towards moving a concept from the research and development phase into prototype development to perform experimental evaluation of how such a project would perform in real-life scenarios. We intend to build on strengths and overcome past design weaknesses through cross-industry innovation to create a more robust mechanism that is capable of carbon capture and regeneration.

This paper aims to identify the potential of natural ventilation for cooling a representative two-bedroom residential apartment layout in India. India faces an unprecedented demand for residences and must reduce energy consumption associated with air-conditioning. Three significant climates and cities in India are investigated in this paper. The potential to extend the hours of the year for which thermal comfort is achievable using natural ventilation strategies is tested. This potential is identified by employing analytical methods to design and size ventilation capacity. Five natural ventilation design strategies are used over several scenarios varying window free area and ceiling fan speed. Indoor temperature setpoints are based on the India Model for Adaptive Comfort. Results are given as percentage of hours of the year for which natural ventilation is capable to remove calculated heat gains. Percentages of hours are divided into day-time and night-time. Findings show that the combination of large windows or balcony doors with additional ventilation openings and ceiling fan increases the total percentages of hours of the year for which natural ventilation is effective impacting on substantial energy consumption reduction with air-conditioning. Conversely, this potential varies with climate, and hence location.

Buildings consume 33% of total energy (24% domestic and 9% commercial) in India and this is growing at 8% per annum. Reliance on fossil fuel and increasing demand for energy has led to having an unregulated energy use in buildings in India. Despite multiple instances of green buildings existing throughout India wide-scale adoption of green building practices have not been observed. This leads to higher than predicted energy use. Building Performance Evaluation is essential to reduce this gap and help buildings perform better. Despite the improvements in building systems and services, energy efficient building design and implementation – there is a growing gap observed between the intended and actual performance of buildings leading to higher than expected energy use. The purpose of this study is to understand this performance gap for a university building. The study evaluates the actual performance of this building through on-site measurements and provides feedback for the building to perform better.

Town housings are facing good prospects and will play an important role in energy-saving and emission reduction in the future. As the main energy resource for heating, coal utilization in the severe cold region is worthy of attention. With data from the 2016 Northeast towns investigation, this paper estimated coal utilization in town housing by calculating expenditure. The investigation covered 4 aspects: basic household information, family living conditions, residential housing characteristics and energy utilization. Town residential coal utilization in Jilin Province is the most, while Liaoning Province is the least. Household appliances, cooking fuel, central heating, heating tools, housing area and monthly income are analysed as factors of residential coal utilization.
