“…It has also been used to evaluate the future options for coal-fired power-plants in the US [192], the impact of carbon reduction policies on the electricity sector [193], to analyse more energy-efficient technologies in the US building sector [194], and renewables on the US energy markets [195]. NEMS has simulated a renewable-energy penetration of 25% in the electricity sector and 12% in the transport sector [196].…”

“…Table 3, shows a semiquantitative market analysis and suggested energy saving measures, based on various national policy studies. [21][22][23][24][25][26][27][28][29][30][31][32] Efficient building envelopes with double or triple glazing, insulated walls, and a high degree of air tightness are standard in Europe, less so on the American continent, and adopted to an even smaller extent in Asia and in the rest of the world. Particularly airtight building envelopes are standard for new construction in Europe but not really for the rest of the world.…”

Buildings account for ∼40% of global energy demands, and the increased adoption of innovative solutions for buildings represents an enormous potential to reduce energy demands and greenhouse gas emissions. Here, we critically review the current and future materials and solutions for the construction sector. We describe how policy affects innovative businesses and the adoption of new products and solutions. We investigate how the building envelope and user behavior determine building energy demands. Compared to conventional solutions, superinsulation materials (vacuum insulation panels, silica aerogel) can achieve the same thermal performance with drastically thinner insulation. With low-emissivity coatings and appropriate filler gasses, double and triple glazing reduces thermal losses by an order of magnitude. Vacuum and aerogel glazing reduce these even further. Switchable glazing solutions maximize solar gains during wintertime and minimize illumination demands whilst avoiding overheating in summer. Upon integration of renewable energy systems, buildings become both producers and consumers of energy. Combined with the dynamic user behavior, temporal variations in energy production require thermal and electrical storage and the integration of buildings into smart grids and energy district networks. The combination of these measures can reduce the energy consumption of the building's stock by a factor of three.

“…For most end uses, the Scenarios for a Clean Energy Future (CEF) study was used to estimate savings potential (Interlaboratory Working Group on Energy-Efficient and Clean-Energy Technologies 2000, Koomey et al 2001). For the residential natural gas end uses, we used savings estimates from a recent study of natural gas savings potential in New York state (Mosenthal et al 2006).…”

“…Technology costs were drawn from the CEF "Advanced" case, which assumed a greater penetration of more advanced efficiency technologies. While the CEF study also defined policy pathways to implement these technologies (Koomey et al 2001), we only make use of the technoeconomic potentials it reported. Those savings potentials are based on a "phased-in" approach, which explicitly accounts for stock turnover using retirement functions for buildings and equipment.…”

This paper presents an estimate of the potential for energy efficiency improvements in the U.S. building sector by 2030. The analysis uses the Energy Information Administration's AEO 2007 Reference Case as a business-as-usual (BAU) scenario, and applies percentage savings estimates by end use drawn from several prior efficiency potential studies. These prior studies include the U.S. Department of Energy's Scenarios for a Clean Energy Future (CEF) study and a recent study of natural gas savings potential in New York state. For a few end uses for which savings estimates are not readily available, the LBNL study team compiled technical data to estimate savings percentages and costs of conserved energy. The analysis shows that for electricity use in buildings, approximately one-third of the BAU consumption can be saved at a cost of conserved energy of 2.7 ¢/kWh (all values in 2007 dollars), while for natural gas approximately the same percentage savings is possible at a cost of between 2.5 and 6.9 $/million Btu (2.4 to 6.6 $/GJ). This cost-effective level of savings results in national annual energy bill savings in 2030 of nearly $170 billion. To achieve these savings, the cumulative capital investment needed between 2010 and 2030 is about $440 billion, which translates to a 2-1/2 year simple payback period, or savings over the life of the measures that are nearly 3.5 times larger than the investment required (i.e., a benefit-cost ratio of 3.5).ii
