Buildings currently consume 36% of the world’s energy and contribute nearly 40% of CO2 emissions. Many countries desire to generate virtual models of their nation’s buildings in order to coordinate research activities and inform market opportunities for a more sustainable built environment. The United States Department of Energy uses a suite of Commercial Prototype Building Models, which currently includes 16 building types and covers 80% of US commercial floorspace. Efforts are underway to expand this suite by developing prototype models for additional building types. In this paper, we outline a systematic approach to defining the building, collecting relevant information and creating a flexible model while doing so in the pragmatic context of a courthouse building. Informed by building design guides, databases, documented projects and inputs from courthouse design experts, we define a small, 69,324 ft2 (6440 m2), four-courtroom, low-rise courthouse as the prototype to represent an average-size courthouse in the US. We present building characteristics relevant for energy model development and provide the rationale for their selection. These details combined with climate- and construction-vintage-specific requirements for the building envelope and systems from building standards will be used for developing the courthouse model for the Commercial Prototype Building Models suite. The comprehensive information presented will also guide model modification to capture the dynamics of smaller or larger courthouses more accurately for building or system size-specific research.

Building America (BA) partner McStain Neighborhoods built the Discovery House in Loveland, CO, with an extensive package of energy-efficient features, including a high-performance envelope, efficient mechanical systems, a solar water heater integrated with the space-heating system, a heat-recovery ventilator (HRV), and ENERGY STAR appliances. The National Renewable Energy Laboratory (NREL) and Building Science Consortium conducted short-term field-testing and building energy simulations to evaluate the performance of the house. These evaluations are utilized by BA to improve future prototype designs and to identify critical research needs. The Discovery House building envelope and ducts were very tight under normal operating conditions. The HRV provided fresh air at a rate of about 35L∕s(75cfm), consistent with the recommendations of ASHRAE Standard 62.2. The solar hot water system is expected to meet the bulk of the domestic hot water (DHW) load (>83%), but only about 12% of the space-heating load. DOE-2.2 simulations predict whole-house source energy savings of 54% compared to the BA Benchmark (Hendron, R., 2005 NREL Report No. 37529, NREL, Golden, CO). The largest contributors to energy savings beyond McStain’s standard practice are the solar water heater, HRV, improved air distribution, high-efficiency boiler, and compact fluorescent lighting package.

Research activities in the field of innovative fixtures are continuously aiming at increasing their thermal and optical performances to offer optimal exploitation of daylight and solar gains, providing effective climate screen, according to increasing standards for indoor comfort and energy saving. Within this work, we designed an innovative aerogel-based “thermal break” for window frames, so as to consistently reduce the frame conductance. Then, we compared the performance of this new frame both with currently used and obsolete frames, present in most of the existing building stock. Energy savings for heating and cooling were assessed for different locations and confirmed the potential role played by super-insulating materials in fixtures for extremely rigid climates.

The next step in energy efficiency building design focus on near energy zero buildings. To design such buildings is important to understand how people use low energy building and to find reserves in energy. The paper presents an analysis of reserves in a family house. The analysis is done with simulations of different design and operation solutions based on knowledge from in situ measurements. Results show there are reserves in the heating and cooling period of year, which can lead to further energy savings of up to 15% and internal environment improvements.

Energy Efficient Building

Reducing the energy needs of existing buildings has a significant place in reducing global energy demands. High energy savings can be achieved with passive renovation suggestions in existing buildings. In this study, the effect of the proposed renovations for an educational structure in Safranbolu on the heating and cooling demands of the building was determined with a simulation program. Energy improvements of up to 70 percent have been achieved through passive improvement designs in orientation and insulation material. The highest energy saving (69.31 %) was realized through a scenario of rearranging spaces from the north side to the south side where the number of users is relatively high and selecting a 20 cm aerogel thermal insulation material. While the heating and cooling load, in accordance with the definition of a zero-energy building, could not be reached in this scenario, the study showed the importance of holistic decisions taken in the design phase of the building with respect to energy-efficient building design.

The Van Geet home near Denver, Colorado, demonstrates the successful integration of energy conservation measures and renewable energy supply in a beautiful, comfortable, energy-efficient, 295-m23,176-ft2 off-grid home in a cold, sunny climate. Features include a tight envelope, energy-efficient appliances, passive solar heating (direct gain and Trombe wall), natural cooling, solar hot water, and photovoltaics. In addition to describing this house and its performance, this paper describes the recommended design process of (1) setting a goal for energy efficiency at the outset, (2) applying rules of thumb, and (3) using computer simulation to fine-tune the design. Performance monitoring and computer simulation are combined for the best possible analysis of energy performance. In this case, energy savings are estimated as 89% heating and cooling (compared to 95 MEC), 83% electrical, and nearly 100% domestic water heating. The heating and cooling energy use is 8.96kJ/°Cs˙days˙m20.44Btu/°Fs˙days˙ft2.

Different Characteristics

This study, considering the current conditions of our planet, proposes to analyze how efficient is to renovate building skins to meet energy, economic, and CO2 emission criteria. A building envelope is the part of a building that is most exposed to weather conditions and therefore it has an impact on the internal energy demand of its inhabitants so that they can comfortably there. Studying building skins and their status in terms of energy, economic costs, and CO2 emissions will allow renovation to produce benefits in the medium and long-term. This study was conducted in the neighborhood of Montbau, a housing development of around 30 buildings, each with different characteristics, built in the 70’s and currently having energy losses through their skins, which results in a high demand of internal energy for heating and cooling purposes, in addition to doubled emission of CO2e released into the atmosphere. Improvements are proposed to adapt the conditions of these buildings. Two solutions are proposed in addition to evaluating energy costs caused by CO2e emissions and any other economic costs year 2012. Other studies analyze the behavior of buildings already implementing such solutions and their corresponding energy, emission, and economic reductions. The importance of such studies lays on the need to analyze options such as renovation instead of considering demolition as an alternative, and to suggest the future building of housing developments in pro of the sustainability of our planet and offer an alternative for a sustainable future, housing and shelter under optimal conditions. The figures herein offer solid results in terms of expenses, costs and energy savings, as well as the reduction of CO2 emissions released into the atmosphere. The graphs and tables here contained offer a clear reading and suggest topics for further research and even for starting up building projects, both locally and worldwide.
