Studies of evaporative and conventional cooling of an energy conserving California house

Description: For cooling a Sacramento, California home, (1) higher thermostat settings, (2) insulation (3) ''solar control'' window shades, and (4) the use of an evaporative cooler in the place of a vapor compression cycle air conditioner are studied. A computer program TWOZONE is used to evaluate the effect on energy consumption and peak power. It is calculated that the peak cooling load can be reduced by a factor of 5 or more and the total energy by a factor of 20 or more.

Diagnostic tests determining the thermal response of a house

Description: Two different approaches to the determination of the thermal response of buildings are possible: deterministic models and methods based on equivalent thermal parameters (ETP's) of a building. While the former are computer applications of heat transfer theory, the latter consist of data oriented techniques that infer the ETP's of a particular building by multiple correlation of indoor temperature and weather. The ETP method is convenient to provide a rank ordering of different houses by their th… more

Economic analysis of the integrated heating and cooling potential of a residential passive-solar water wall design

Description: The heating potential of residential water wall designs has been analyzed for many years. Because this past work has been confined strictly to heating potential, it has understated the true energy savings potential of water walls. Preliminary performance estimates for the heating and cooling potential of water walls have recently been made available. These estimates include the Btu displacement that is attributable to a 300-square foot water wall design in a 1200-square foot residence. The desi… more

Comparative Study of Four Passive Building Energy Simulations DOE 2.1, BLAST, SUNCAT 2.4, DEROB-III

Description: Four building energy analysis codes are compared using two direct gain building models with Madison TMY weather data. Hourly temperature profiles and annual heating and cooling loads are compared and discussed. An analytic verification technique is described and used to investigate performance of the four codes. An anomaly is discovered in one of the codes, and the analytic verification technique is used to test a modified version of this code.

Evaluation of the typical meteorological years for solar heating and cooling system studies. Final report

Description: This report is a summary of an evaluation of the weather data set, generated at Sandia Laboratories, known as the Typical Meteorological Year (TMY) Data. The purpose of the evaluation is to determine how well the TMY data represent actual long-term weather data in affecting the performance of solar heating and cooling systems. The two data sets are compared through detailed SHAC simulation.

Furnace Blower Electricity: National and Regional Savings Potential

Description: Currently, total electricity consumption of furnaces is unregulated, tested at laboratory conditions using the DOE test procedure, and is reported in the GAMA directory as varying from 76 kWh/year to 1,953 kWh/year. Furnace blowers account for about 80percent of the total furnace electricity consumption and are primarily used to distribute warm air throughout the home during furnace operation as well as distribute cold air during air conditioning operation. Yet the furnace test procedure does n… more

Data Center Energy Benchmarking: Part 3 - Case Study on an ITEquipment-testing Center (No. 20)

Description: The data center in this study had a total floor area of 3,024 square feet (ft{sup 2}) with one-foot raised-floors. It was a rack lab with 147 racks, and was located in a 96,000 ft{sup 2} multi-story office building in San Jose, California. Since the data center was used only for testing equipment, it was not configured as a critical facility in terms of electrical and cooling supply. It did not have a dedicated chiller system but was served by the main building chiller plant and make-up air sys… more

Development of an Integrated Residential Heating, Ventilation, Cooling, and Dehumidification System for Residences

Description: The Need and the Opportunity Codes such as ASHRAE 90.2 and IECC, and programs such as Energy Star and Builders Challenge, are causing new homes to be built to higher performance standards. As a result sensible cooling loads in new homes are going down, but indoor air quality prerogatives are causing ventilation rates and moisture loads to increase in humid climates. Conventional air conditioners are unable to provide the low sensible heat ratios that are needed to efficiently cool and dehumidif… more

Advanced Energy Efficient Roof System

Description: Energy consumption in buildings represents 40 percent of primary U.S. energy consumption, split almost equally between residential (22%) and commercial (18%) buildings.1 Space heating (31%) and cooling (12%) account for approximately 9 quadrillion Btu. Improvements in the building envelope can have a significant impact on reducing energy consumption. Thermal losses (or gains) from the roof make up 14 percent of the building component energy load. Infiltration through the building envelope, incl… more
