heating and cooling equipment. 18 – Work with a Heating and Cooling Contractor Learn how to choose the right contractor and what to expect from him or her. 20 – Get an ENERGY STAR Quality Installation Choose equipment that is properly sized for your home and make sure your contractor follows ENERGY STAR guidelines for a quality installation. Prolonged exposure to low indoor temperature is a threat to human physical health. This study characterizes indoor human thermal comfort conditions in typical low-income residential dwellings during the winter season. Mapping indoor human thermal comfort can assist in exploring the potential for domestic thermal insulation retrofits interventions.

  The present paper aims to investigate the characteristics of airflow inside the room with insect proof screens by employing computation fluid dynamics (CFD) technique. Insect proof screens attached to the window openings were simulated by porous media approach. The simulated pressure drop across the insect proof screen was compared with the experimental result and is having a good Cited by: 7. The increase of outdoor temperature in June has a prompt impact on the amount of the energy used which is proportional to the temperature rise as depicted in Figure 2. The maximum energy consumed is KWh and it is spent during the time the temperature is at its largest value which was 35 ˚C for : Asimina Dimara, Christos Timplalexis, Stelios Krinidis, Dimitris Tzovaras.

significant impact on the results. Even one degree Fahrenheit difference in heating set point can make a 5% difference in heating energy use. This is the single largest occupant-driven variable (Robertson et al., ) in residential simulations today. 1. Figure 1. Relative sensitivity of 24 influential inputs in residential simulation Size: 1MB. The Residential Building Systems group (RBS) works on problems associated with whole-building integration involving modeling, measurement, design, and operation. Most of its tasks focus on the movement of air and associated penalties involving distribution of pollutants, energy and fresh air.

Residential Indoor Temperature Study. United States. doi/ Simulations are used to set Building America goals, predict the impact of new building techniques and technologies, inform research This best practices guide for residential HVAC system retrofits is aimed at contractors who want guidance on delivering energy.

Study of households participating in a program of improving the efficiency of home heating. RE-effect between 8 and 13%. An analysis of the impact of residential retrofit on indoor temperature choice (Dinan, ) Study of a sample of households whose dwellings were by: and field measurements on indoor air temperature character and the nature of residential thermal environment, during the rainy and dry seasons of This was carried out to get a variation measurement in terms of the indoor and outdoor temperature, relative humidity and air velocity.

Table5 Major effects of existing residential building retrofit Major effect of transformation Proportion (%) Increase the indoor temperature Improve the house’s moisture and condensation in winter Improve the house’s cold wind penetration Improve the living environment of residential Reduce the interior noise Rest From the reasons of retrofit, the energy efficiency retrofit Cited by: 3.

Analysis of the electricity billing data suggests that these households increased their indoor temperature settings after retrofit by almost 1 °F on average. This temperature increase led to an estimated average loss of almost kWh of electricity by: Indoor temperature changes in retrofit homes average °F drop in reference temperature.

This is partly offset by the reduction in baseload, which yields an increase in reference temperature Cited by: humidity. While the indoor air temperature remained independent, the humidity was varied in the study.

This relationship was achieved by finding the linear, quadratic cubic and other available values in the SPSS The scatter graph of the indoor air temperature against indoor relative humidity. Fig 2 further illustrates the quadratic model.

The analysis determined the possible period that indoor cooling or heating might be required with and without green roofs and demonstrated the positive impact of green roofs in moderating the roof temperature and temperature fluctuations, which in summer was remarkable.

A simple analysis of the comfort was made by considering the number of hours in which indoor temperature is below 18 °C. Similar conditions were obtained for all the scenarios, where the number of hours below 18 °C ranged between 0 and a maximum value of 37 h, depending on the indoor temperature by: OUTDOOR-INDOOR TEMPERATURE RELATIONSHIPS Bruce Nordman and Alan Meier Lawrence Berkeley Laboratory ABSTRACT We investigated the relationshjp between outside and inside temperatures for several hundred houses in the Pacific Northwest.

A study of residential buildings in Bauchi state, Nigeria shows that most occupants of the buildings have persistent and growing problems with the indoor environment due to high indoor temperature.

The behavioral response (e.g. changes in indoor temperatures, attention to window and door openings) to residential technical efficiency improvements (e.g.

attic insulation, storm windows) is an important and largely unresolved issue. Although there is considerable discussion concerning the extent to which households take back some of the energy savings due to. Thermal Efficiency Retrofit of Residential Buildings: The German Experience September CPI Report Page 5 Such an argument does not take into account, however, many of the considerations of building owners.

For example, we found that of retrofit jobs sold by a local retrofit company, the homeowners cited comfort reasons in ANALYSIS. Indoor thermal conditions of ten residential buildings of Liege have been monitored. For space reasons, the results of only two houses (house number 8 and 9) are presented in this paper.

It has been estimated that if energy retrofit works are carried out in an average income UK household with a mean internal temperature of °C, only 70% of the energy efficiency benefit will result in reduced fuel demand and 30% will be used to increase indoor temperatures.

This figure increases to 50% for a low-income household with mean Cited by: The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years.

Figure 2 shows a scatter plot of the indoor air temperature vs. indoor relative humidity for further illustration. The relationship between indoor air temperature (T a) and relative humidity (RH(KK−in)) during field study was best described with a quadratic model (n =r = 0.r2 = Adjusted r2 =F =P Value = 0 File Size: [email protected]{osti_, title = {Analysis of savings due to multiple energy retrofits in a large office building}, author = {McLain, H A and Leigh, S B and MacDonald, J M}, abstractNote = {The objective of this analysis was to characterize the benefits of the individual energy conservation measures that were applied to an existing large office building.Thermal Comfort: Designing for People 5 buildings and equipment, we were left with less dehumidification.

This is problematic from an indoor air quality standpoint as increased moisture can cause mold or mildew to grow inside the building, which is a health hazard for occupants and detrimental to the life of build-ing materials.
