Building renovations and the ghost of green premiums
The benefits of higher energy quality buildings such as lower energy bills do not currently translate into higher building values. Reducing energy consumption has a direct positive impact in the form of reduced energy bills, however, when selling the asset, at the moment, there is no evidence that buyers would recognise this value. In-depth research shows that although buildings with A or B ...

Exergy analysis combined with LCA for building envelope energy efficiency retrofit
This article presents a kind of exergy analysis combined with LCA to evaluate the building envelope energy efficiency retrofit. A typical case in Ningbo city of China is analysed. The results show that it takes 15 years for the cumulative saved energy consumption in the use stage to equal the embodied energy of the newly added insulation materials in the product stage. Yet, it is impossible that ...

Dedicated to making a difference
Based on 2050 projections, energy savings in buildings could save more carbon dioxide than the entire emissions of the transport sector. Knowledge and technology available today could achieve these dramatic reductions in building energy consumption, but it is happening only at a snail’s pace. Market and policy failures and behavioral barriers stand in the way of achieving the huge progress that ...

Climate Adapted Buildings
Acknowledging our power-hungry practices and demanding a proper understanding of the fundamental laws of physics within the context of a building. The single-greatest environmental impact of buildings today is their ongoing energy usage, which accounts for almost half of global energy usage. Heating, ventilation, and air conditioning (HVAC) requirements of conventional buildings represent more ...

Sustainability as a matter of social context: information technologies and the environment
The paper focuses on the potential of Information and Communication Technology (ICT) to improve the sustainability of residential buildings. While ICT can contribute to improving building energy efficiency (e.g., energy management systems) there are also plausible scenarios of an increasing energy demand triggered by ICT use. The main argument of this paper is that harnessing the sustainability ...

From compliance to measuring the actual energy use of a building
Looking in greater detail at energy consumption has begun to show that buildings often fall short of targeted performance. One reason for this is a disconnection between design, procurement and operation of a building. Compliance calculations do not fully address factors relating to building occupation and operation, with EPC effectively leaving occupants out of the equation, although they ...
