“…A number of studies have documented the BEE development status and future development and its contribution to energy savings and GHG mitigation in both developed and developing countries (see for example Marszal et al, 2011;Gustavsson and Joelsson, 2010;Peuportier et al, 2013;Huang et al, 2012;Broin et al, 2013;Griego et al, 2012). Due to its sizeable buildings' stock and rapidly growing property market with stunning construction speeds in the newly urbanised areas, buildings' energy performance plays a critical role in shaping energy and environmental prospects in China and has received increasing attention in recent buildings' research literature with numerous publications on this subject.…”

a b s t r a c tThe optimal ventilation rate in a dwelling is a trade-off between the requirement to minimize ventilation heat losses to help meet national greenhouse gas emission targets and the need to minimize adverse health impacts arising from exposure to cold temperatures and pollutants from indoor and outdoor origin. This paper presents approaches for exploring these trade-offs based on two implementations of multi-objective optimization that consider both energy efficiency and health impacts. Both methods aggregate the various performance criteria into a single criterion, but the first method monetizes the performance criteria, while the second method weights them in a more general way.Unlike in the monetization approach, the generalized multi-objective optimization approach is found to be robust against scaling of the health impacts and energy savings that is independent of the ventilation rate. As a result it is less sensitive to assumptions made in the models regarding heating system efficiency, absolute health burden level, and dwelling occupancy. It is however sensitive to assumptions regarding pollutant production rates and balance-point temperatures, which affect health impacts and energy savings in a way correlated with ventilation rate.A preliminary application of the methods to a typical UK flat and detached house finds that the optimal ventilation rate may vary with built form. Application of the generalized multi-objective optimization approach in which health impacts and energy savings are equally weighted, suggests an optimal annual average air change rate of 0.4/h for the detached house, and 0.7/h for the flat.Crown

“…The greatest savings were calculated for Mexicali (1941-4181 kWh/year); while the cost-benefit analysis showed that the most favorable net impact of thermal insulation was for the cities of Mérida, Villahermosa, Monterrey and Nuevo Laredo. Griego et al (2012) [33] investigated the interactions between various energy efficiency measures for residential buildings in Salamanca, a city in central Mexico. The reference building had an area of 110 m 2 .…”

“…The highest impact occurs in coastal areas, where cooling is more common than heating, and in the northern states, where both cooling and heating are commonly used even in low-income households. Air conditioning and heating systems are less common in the cities of central Mexico, such as Salamanca [33] and Toluca [39].…”

The Effects of Roof and Wall Insulation on the Energy Costs of Low Income Housing in Mexico

Abstract:Environmental conditions, such as air temperature and solar radiation, have a complex relationship with the energy requirements for heating and cooling of residential buildings. In this work, a comparative analysis of the insulation methods most commonly applied to low income single-family houses in Mexico is presented, in order to find the most energy-efficient combinations of methods for the various climates in this country. A common kind of building, small houses built with hollow cinder block walls and concrete slab roofs, was analyzed considering three insulation scenarios: walls only, roof only and both. We used dynamic simulation to evaluate energy consumption under the climate conditions found in several Mexican cities. From the energy consumption data and the cost of electricity in Mexico, we calculated net annual energy costs, including both annual energy savings and the annualized cost of the initial investment in better insulation. Results of this analysis show that insulating both roof and walls is most effective in cities with cold winters; insulating just the roof is best for temperate climates; and insulating walls (combined with high-albedo roofs) is most effective for cities with year-long warm weather.
