Abstract Single family houses contribute substantially to climate change in the US and other parts of the world. In the US specifically, most housing has been designed by builders and developers. The motivation has not been sustainability and a knowledge of how to design net zero energy and net zero water dwelling is not commonly understood. This paper seeks to use a historical model as viewed through the lens of the Living Building Challenge to demonstrate how an architect designed historic example might provide a way of implementing a cutting-edge approach to sustainable housing today. Arthurdale was an early 20th century housing experiment that was conceptualized to provide for sustainable living in rural Appalachia. This paper presents the history of the region, an overview of the houses and the Living Building Challenge and then analyses how this historic prototype might model a sustainable housing development today using the Living Building Challenge system.

Healthy Housing

In response to the growing demand for zero-energy housing, today's home needs not only to be energy-efficient, but also to provide part of its own energy requirements. The energy efficiency may be improved by applying high thermal performance building envelope and passive energy and environmental systems to housing. Micro-power can be generated through the use of renewable energy technologies. This paper is aimed at providing a comprehensive guideline on the design techniques and approaches to the delivery of net zero-energy healthy housing in view of the ÉcoTerra house, which won the Canadian federal government's EQuilibrium sustainable housing competition. The house was built in Eastman in the province of Quebec and it is currently open to the general public in order to sharpen the consumers' awareness of commercially available net zero-energy healthy housing today.

Buildings account for 34% of world energy consumption and about half of electricity consumption. The nearly/Net Zero Energy Building (nZEB/NZEB) concepts are regarded as solutions for minimizing this problem. The countries of Southern Europe, which included the nZEB concept recently in their regulatory requirements, have both heating and cooling needs, which adds complexity to the problem. Brazil may benefit from their experience since most of the Brazilian climate zones present significant similarities to the Southern European climate. Brazil recently presented a household energy consumption increase, and a growing trend in the use of air conditioning is predicted for the coming decades. Simulations with various wall and roof solutions following the Brazilian Performance Standard were carried out in a low standard single-family house in three different climate zones in order to evaluate thermal comfort conditions and energy needs. Results show that in milder climate zones, achieving thermal comfort with a low energy consumption is possible, and there is a great potential to achieve a net zero-energy balance. In the extreme hot climate zone, a high cooling energy consumption is needed to provide thermal comfort, and the implementation of a nearly zero-energy balance may be more feasible.

Buildings in Canada account for a significant amount of greenhouse gas (GHG) emissions and net zero energy building technology has been identified as part of the solution. This study presents a conceptual model identifying barriers to the adoption of net zero energy housing and tests it by administering a survey to 271 participants in a net zero energy housing demonstration project in Toronto, Canada. Using multivariate correlation and multi-linear regression analyses this study finds that of all the innovation adoption variables it was the construction and design quality that was the most significant contributor to the adoption of a net zero energy home by a potential home owner. This study found that the (a) extra cost compared to a conventional home, b) lack of knowledge about the technology associated with a net zero energy home or (c) not knowing someone who owned a net zero energy home were not significant barriers to accepting net zero energy homes. Our results suggest that policy-makers should promote the diffusion of net zero energy home technology by encouraging housing developers to include net zero energy homes in their collection of model homes, with an emphasis on quality design and construction. Furthermore, engaging in trust building initiatives such as education and knowledge about the technology, its related energy cost savings, and the environmental benefits would contribute to a greater acceptance of net zero energy homes.

Global climate change is serving as warning signs it gradually begins to capture the attention of people at large. Many actions have been and continue to be taken by governments and organizations to preserve the planet, which is impactful and needed. But conservation efforts are not exclusive to governments and large institutions- individuals can contribute in multiple ways that will have ripple effects, one being the choice to build sustainable, net-zero energy homes. Building a house that is a net-zero energy requires many strategies.One of the most compelling factors in reducing the home energy consumption, to then achieve a net-zero energy home especially in hot-dry regions, is the optimization of the building envelope performance. This paper discussed several building envelope design strategies that are suitable for homes in hot-dry regions and tested them.The Methods including analyzing case study from Qater by using computer and were analyzed using Building Information Modeling (BIM) tools for energy simulation programs. All those strategies were applied to a design proposal for a house in Riyadh, Saudi Arabia, which is a hot-dry region. Further, the same simulation analyses were projected onto an identical house to the design proposal, but with a traditional, low-efficient building envelope.The results showed that the house with the high-efficient building envelope had 48% less energy consumption than the one that has the low-efficiency envelope.This research demonstrated the efficacy of the building envelope to reduce the energy consumption of single-family homes in hot-dry regions. The study outlines vital strategies for a high-efficient building envelope design in hot-dry areas that reaching net-zero energy homes and thus help to offset the negative impact of climate changes in arid areas.

The energy design of a building is a multivariable problem, which can accept different sets of solutions. In this paper an integrated energy design process is proposed to support designers in identifying the most suitable set of passive solutions to guarantee a comfortable indoor environment and hence to minimize its energy needs for space conditioning. The proposed design process uses EnergyPlus as energy simulation engine, guided by GenOpt via some code written by the authors. The optimization aims at minimizing two seasonal long-term discomfort indices (based on the ASHRAE Adaptive comfort model) through the Particle swarm optimization algorithm. We test here the proposed process in a case study where we identify the most suitable envelope components and passive strategies for the design of a single-family net zero energy home located in the Mediterranean climate. The building is now actually under construction. It should be noted, however, that the modeling and the optimization approach outlined in this paper can be applied to any residential or commercial building prototype.

Abstract In this paper, a resiliency analysis is conducted to assess the energy, economic, and outage survivability benefits of efficient and Net-Zero Energy (NZE) communities. The analysis addresses the design of an energy-efficient and NZE community using Phoenix, Arizona as the primary location. The loads from the baseline, energy-efficient , and NZE single-family homes modeled in BEopt are used to determine load profiles for various residential community types. The photovoltaic (PV) and battery storage system sizes necessary for the community to survive a 72-hour power outage are determined using REopt. The economic analysis indicates that it is 43% more cost-effective to install a shared PV plus storage system than to install individual PV plus storage systems in an energy-efficient community. It is found that only a 4% difference in net present cost exists between a PV plus storage system sized for a 24-hour outage and a 144-hour outage. In the event of a community-wide lockdown, the survivability of the energy-efficient community is only 6 hours during a time where plug loads are increased by 50% due to added office electronics. A climate sensitivity analysis is conducted for efficient communities in Naperville, Illinois and Augusta, Maine. The analysis suggests that for a 72-hour power outage starting on the peak demand day and time of the year, the cost of resiliency is higher in climates with more heating and cooling needs as HVAC is consistently the largest load in a residential building.
