“…Four categories of dwellings have been considered HTT; dwellings with solid walls, dwellings off the gas network, dwellings with no loft and high-rise flats." Such implications have been discussed in previous studies, particularly those surrounding the feasibility of achieving the UK carbon reduction targets and the level of impact that policy might have on users' behaviour to support achieving these targets [23][24][25]. Other studies [26][27][28] found that lifestyles, habits, and social-demographic characteristics have a direct influence on pat-terns of domestic energy consumption.…”

Improving household energy efficiency is regarded as key to significantly curtailing domestic greenhouse gas emissions. Various policy instruments have been introduced to retrofit the existing domestic building stock in the UK; however, many fail to acknowledge the significant role that occupants' lifestyle play in energy use. The research discusses the results of a survey questionnaire administered to the residents of one of the pilot CESP schemes in Aspley, Nottingham. Factors affecting domestic energy consumption are explored, some of which relate to the building design, while others are under the direct control of the occupants. Significant findings related to home performance, home energy use, and tenants' lifestyle are investigated in the first phase of the research. The total number of responses to the survey represents 10% of around 900 properties eligible for the CESP scheme that have not been approached for the scheme uptake. It is evident from the survey results that the majority of the sample is aware of the basic energy-saving actions in everyday life but are not likely to take up the more difficult actions. In summary, retrofit programmes will reduce carbon emissions to some degree, whereas the bigger challenge is addressing habitual household energy consumption.

“…Since then, the technological functionality of energy savings in buildings has been widely studied (e.g., [11][12][13]) and earlier studies on the general barriers and drivers in energy-efficient construction and green building have found that other elements than the technology itself affect the innovation processes. Regulation, the conservative nature of building industry and rising energy prices have been identified as common factors affecting these innovation processes [14,15].…”

How to Succeed in Low-Energy Housing—Path Creation Analysis of Low-Energy Innovation Projects

Abstract:The low-energy and the nearly zero-energy buildings trend is calling for radical new innovations from the construction industry. This study uses path creation theory to examine two innovation concepts for low-energy housing in Northern Europe with contrasting outcomes-with one being an apparent market success and the other a disappointment. The results highlight two issues behind the success, one of a systemic nature and the other concerning innovation management. First, the development of energy efficiency regulations and the dominant technological trajectory regarding low-energy houses are interdependent. However, it seems that while supporting the trajectory of the innovation developed in the first case, regulators created virtually insurmountable cognitive and normative obstacles to finding alternative technological pathways. Second, the significance of proof of concepts for new innovations cannot be underestimated. The importance of a pilot project rests not only on showcasing and testing the technology, but also on its ability to increase political support, investments, and public awareness. The study implies that low-energy construction seems to be the next great challenge, one where genuine co-operation between the industry, public authorities and academia is a prerequisite for success.

“…However, the electric power needed to operate MVHR makes them part of "parasitic energy demand" systems [14]. Poor filter performance or maintenance has also been found to lead to an increase in the energy consumed by an MVHR system by up to 3% [11]. The essential ductwork, the potential difficulty of installation in certain buildings (e.g., hospital buildings), as well as capital and maintenance costs, are issues which might affect the practicability of such systems.…”

Abstract:In temperate countries, heat recovery is often desirable through mechanical ventilation with heat recovery (MVHR). Drawbacks of MVHR include use of electric power and complex ducting, while alternative passive heat recovery systems in the form of roof or chimney-based solutions are limited to low rise buildings. This paper describes a biomimetic concept for natural ventilation with heat recovery (NVHR). The NVHR system mimics the process of water/mineral extraction from urine in the Loop of Henle (part of human kidney). ), respectively, for the month of January. With active heating and single occupant, the LoH Chamber consumes between 65.7% and 72.1% of the annual heating energy required by a similar naturally ventilated space without heat recovery. The LoH Chamber could operate as stand-alone indoor cabinet, benefitting refurbishment of buildings and evading constraints of complicated ducting, external aesthetic or building age.
