The Energy Conservation Act 2001 was the first major initiative in India to channelize and catalyze energy efficiency improvement in various sectors of economy. The Bureau of Energy Efficiency was set up per the provision of this act, which in 2007 brought out Energy Conservation Building Code (ECBC) with an overall purpose of providing minimum requirements for the energy efficient design and construction of buildings. ECBC covers building envelope, heating, ventilation and air-conditioning system, interior and exterior lighting system, service hot water, electrical power and motors. Since the launch of this code in May 2007, efforts are being made to promote and facilitate the adoption of this code through several training and capacity building programs. A program committee has been set to take care of the comments from stakeholders and inconsistencies, due to which revision of the code was brought out in May 2008. Currently the code is voluntary in the initial phase, but it is designed to be mandatory in future. One major feature of the code is that implementation is left under the scope of State and local governments. During the capacity building effort, a need was felt to provide additional guidance to design and construction professionals on the rationale behind the ECBC specifications and provide explanations to the key terms and concepts. The ECBC User Guide was therefore developed and released in July 2009 for this purpose. This paper describes the current status, experiences during capacity building and market transformation required for successful implementation of this code. It also covers commentary on how various stakeholders are contributing towards one common goal in different ways. With successful implementation, the code is expected to reduce the energy consumption of the upcoming new buildings by 20–40% from their average performance level at the time of launch of ECBC. Having this huge potential of energy saving, there is an urgent need to address the problems and issues for early adoption of the energy conservation building code in the country.

Purpose Regarding the contribution of Australian small-size housing in the enhancement of total energy consumption of the country and the roles of the occupants’ preferences in successful implementation of action plans, the purpose of this study is to identify the Australian occupants’ collaborative image of housing energy efficiency. The two main objectives are, therefore, to address the main energy-related housing physical factors that have the potential in representing the housing image of Australian occupants and to explain the causal factors that make the physical factors critical to their energy efficiency perception. Design/methodology/approach This study has been developed through a qualitative approach. Given that the images encompass a wide range of information expressing human perceptions, an online photo-based qualitative survey was developed based on previous research works. The survey includes respondents’ demographic profiles and the evaluation of images, asking for their perception of overall housing energy efficiency, the impacts of building envelope physical attributes on the energy efficiency of the houses and the reasons behind the selection of different attributes. Findings This study has developed a set of attribute-based factors, explaining occupants’ collective perception of energy efficient small-size housing of Brisbane in the area of exterior aspects of the buildings. Specifically, the collaborative image of small-size housing of Brisbane is about the thermal performance of the buildings provided through passive climatic principles by using more efficient envelope features, e.g. material, colour, transparency, texture, openings, balconies and shadowing devices, while ignoring the impacts of architectural composition principles along neighbourhood quality. The key attributes in assessing the small-housing energy efficiency are ventilation, thermal performance and shadowing. The housing images in old traditional architectural style with rural face, built by stone, brick and concrete in high dense vegetation were evaluated to be more energy efficient than those with modern architecture, built by large glass panel and metal cladding with light or no vegetation. Research limitations/implications The main limitation of the paper is related to the nature of an image-based survey, which leads to ignoring some aspects of real spaces such as odour, temperature and noise. Practical implications This research has the potential for developing a practical methodology for assessing housing-resident fit using computer-based methodology and neural networks. Social implications This research has the potential for developing a methodology, assisting the end users in meeting their desires and motivations by helping them in assessing how a housing unit fits with their expectations and preferences. Originality/value This research provides a reliable conceptual platform for dealing with the complexity of occupants’ housing perceptions. This is achieved by establishing a collective conceptual picture of these environmental perceptions, namely, housing image, which is a platform for transferring abstract data related to human perception into measurable and quantitative scales.

Increasing Demand

Until recently, renewable energy technologies (RETs) have been confronted with a huge up-front cost due to technologies in development. However, massive and global deployment of renewable energy systems has led to significant cost reductions and performance improvements and the hope is to see increasing uptake of RETs by African countries. Cameroon a central African country is heavily reliant on hydropower, which contributes an estimated 60% to the country’s total installed 1,400MW capacity in 2015. In addition, there is constants power failure due to the non-reliability of the electric grid and load shedding to meet increasing demand and or to relieve stress on the primary energy source when demand for electricity is greater than the primary power source can supply. However, climate change poses additional huge risk (large reservoirs and dams drying up) and to meet the increasing demand, Cameroon is being forced to seek alternative power sources. In January 2014, Cameroon welcomed its first 72MW solar photovoltaic plant as well as the construction of a 500MW solar photovoltaic park in Q3 of 2015 in the northern region of Cameroon. It is common practice that energy efficiency and energy conservation lead to environmental sustainability. “Energy security starts with energy efficiency and the most sustainable energy option or system is energy conservation”. While it is common practice that energy efficiency and energy conservation lead to environmental sustainability, the building envelope also plays a key role in energy usage, energy conservation and thermal comfort for the building occupants. The rate of infiltration/leakage rate detect the rate of energy usage and cost of using energy. Having a tide and well-constructed building envelope is a key factor and helps reduce/reconcile buildings gas and electricity consumption. RETScreen Expert is the most current version of the RETScreen software and was released to the public on September 19, 2016. The software allows for the comprehensive identification, assessment and optimization of technical and financial viability of potential renewable energy and energy efficiency projects; as well as the measurement and verification of the actual performance of facilities and the identification of energy savings/production opportunities [1-3]. This paper will demonstrate how the software can be use in the design, feasibility, performance assessment and optimization of technical and financial viability of potential renewable energy and energy efficiency projects related to photovoltaic, solar thermal, building envelope and the replacement of non/less-efficient electrical equipment with more efficient and cost effective lamps like LEDs and the installation of smart power bars with automatic shut off function for TV screens, to take care of phantom power in large scale hotels. This approach will further reduce electricity usage and help diversified the sources of energy for a country like Cameroon, which is often subjected to constant power failure and load shedding to either relieve the stress on a primary energy source when demand for electricity is greater than the primary power source can supply or to meet power supply during the critical seasons.

Despite various government policies promoting energy efficiency in buildings over the last 15 years, Cyprus is still associated with a large untapped energy efficiency potential in this sector. The impact of different policy scenarios on future energy needs of the building sector in Cyprus is explored by first reviewing the current status of the building stock in Cyprus and existing national landscape of energy efficiency policies. Various new policies are then proposed to complement the existing framework and help exploit further the potential. Using the Invert/EE-Lab model, three policy scenarios extending to 2050 are assessed with the aim to estimate the energy efficiency potential of the Cypriot building sector and identify policy solutions to harness this potential. The energy consumed for heating, cooling, hot water, and lighting in the entire Cypriot building stock is expected to drop by up to 16% in 2050 compared to the baseline scenario. Under the most ambitious scenario, nearly 60% of the building stock in 2050 will be energy efficient, consuming less than half of the energy used by the average building stock in 2012. Taking into account the modelling results, recommendations on how to improve the financial landscape in buildings until 2050 are presented.

This paper aims to highlight the potential of solar water heater installations in Morocco. The project involves the comparison of active and passive solutions for energy efficiency in buildings. To this end, a numerical simulation model of solar water heater installations is created under TRNsys. Three hot water demand scenarios (Low, Standard, and High) were taken into account for the six climatic zones defined in the Moroccan thermal regulation of constructions. The same software (TRNsys) is used to model a pilot building consisting of 16 flats. Energy efficiency actions have been applied to the building envelope (insulation and glazing) and simulations are made for the six areas. The simulation results comparing energy and financial savings show the influence of subsidized gas prices on solar water heaters’ relevance despite significant energy savings. This work proves that solar water heaters will be a primary obligation for Morocco, taking into account changes in butane gas prices.

The scientific and reasonable departmental collaboration is the key to effective energy conservation work carried out by local governments. This study collects energy-saving policy texts and energy efficiency data of 121 local governments, uses data mining, social network analysis, and related analysis methods to analyze the departmental collaborations in local government energy-saving, and reveals the main problems in departmental collaborations. The results show that: from the structural law, the collaborations with the Department of Water Resources should be strengthened, and the collaborations with Department of Culture and Tourism and Department of Education should be reduced, which can improve energy efficiency. The main problem of current departmental collaborations is that Department of Water Resources is facing obvious lack of collaborations, and the collaborations between relevant departments and Department of Water Resources should be strengthened.

Energy conservation and human thermal comfort enhancement in buildings is a topical issue of modern architecture and construction. The innovative solution of this problem makes it possible to enhance building ecological and maintenance safety, to reduce hydrocarbon fuel consumption, and to improve life standard of people. The requirements to increase of energy efficiency in buildings should be provided at all the stages of building's life cycle that is at the stage of design, construction and maintenance of buildings. The research purpose is complex analysis of energy efficiency in operated high-rise residential building. Many actions for building energy efficiency are realized according to the project; mainly it is the effective building envelope and engineering systems. Based on results of measurements the energy indicators of the building during annual period have been calculated. The main reason of increase in heat losses consists in the raised infiltration of external air in the building through a building envelope owing to the increased air permeability of windows and balcony doors (construction defects). Thermorenovation of the building based on ventilating and infiltration heat losses reduction through a building envelope allows reducing annual energy consumption. Energy efficiency assessment based on the total annual energy consumption of building, including energy indices for heating and a ventilation, hot water supply and electricity supply, in comparison with heating is more complete. The account of various components in building energy balance completely corresponds to modern direction of researches on energy conservation and thermal comfort enhancement in buildings.

Risky Business

In the last two decades, local governments have increasingly engaged in energy conservation and sustainability programs and policy. However, the benefits of these policies (i.e., cleaner air, less congestion, etc.) are often perceived as dispersed and costly. As such, localities consider collaborating with one another. However, decisions to collaborate pose considerable risks that can be magnified or mitigated by the mechanisms through which collaboration occurs. We investigate decisions to engage in formal and informal collaboration in the area of energy efficiency and conservation as a response to collaboration risks.
