“…The urban environment therefore needs attention: about 30-40% of the total energy consumption in western countries is assigned to buildings. About 50% of these refer to the energy consumption for indoor air conditioning (heating and cooling) (Pulselli et al, 2009). Regarding the effects of climate change on the built environment Roberts (2008) clarifies that buildings play an important role in both adaptation and mitigation.…”

In the near future global environmental issues, such as ensuring clean air, water, no pollution and assuring the future sustainability of our planet and its resources will drive developments in land use changes, transport policies, energy and carbon pricing and other climate change mitigation and adaptation policies. Urban and peri-urban areas hugely affect global climate change since they consume as much as 75% of commercial energy; generate as much as 80% of all waste and 60% of greenhouse gas emissions 3 . We argue that in view of climate change the need and demand for the collection, management and use of reliable spatial information and communication technologies (or Geo-ICT) intensifies to assure the integrated sustainability of the policies used to tackle global, national and local environmental issues. Based on three case studies (the Dutch Kadaster, HeatMap Overlay and the Solar Atlas of Berlin) and a review of recent empirical and policy literature, our findings support the view that cadastres and land registration organizations have an important role to play as part of a wider spatial information infrastructure in adapting and mitigating climate change in cities as a core and part of a wider spatial information infrastructure essential for sustainable urban governance.

“…A comparative analysis was carried by Pulselli et al [74] between 3 wall designs (reference, plus insulated and ventilated) in three cities (Berlin, Barcelona, Palermo). From the payback time given by the author the EROI varies from 8.2 to 13 for the plus-insulated design and from 9.7 to 15.8 for the ventilated wall.…”

Abstract:It is often claimed that the cheapest energy is the one you do not need to produce. Nevertheless, this claim could somehow be unsubstantiated. In this article, the authors try to shed some light on this issue by using the concept of energy return on investment (EROI) as a yardstick. This choice brings semantic issues because in this paper the EROI is used in a different context than that of energy production. Indeed, while watts and negawatts share the same physical unit, they are not the same object, which brings some ambiguities in the interpretation of EROI. These are cleared by a refined definition of EROI and an adapted nomenclature. This review studies the research in the energy efficiency of building operation, which is one of the most investigated topics in energy efficiency. This study focuses on the impact of insulation and high efficiency windows as means to exemplify the concepts that are introduced. These results were normalized for climate, life time of the building, and construction material. In many cases, energy efficiency measures imply a very high EROI. Nevertheless, in some circumstances, this is not the case and it might be more profitable to produce the required energy than to try to save it.

“…In the literature, researchers rarely discuss heat flow through building envelopes; thus methods for heat loss calculations are needed in order to make decisions for future energy-efficient buildings (Pulselli et al, 2009). Calculation of heat loss is the first step before selecting a suitable heating system for a greenhouse (Esen & Yuksel, 2013).…”

A Building Energy Simulation (BES) model based on TRNSYS, was developed to investigate the overall heat transfer coefficient (U-value) of greenhouse covers including polyethylene (PE), polycarbonate (PC), polyvinyl chloride (PVC), and horticultural glass (HG). This was used to determine the influences of inside-to-outside temperature difference, wind speed, and night sky radiation on the U-values of these materials. The model was calibrated using published values of the inside and outside convective heat transfer coefficients. Validation of the model was demonstrated by the agreement between the computed and experimental results for a singlelayer PE film. The results from the BES model showed significant changes in U-value in response to variations in weather parameters and the use of single or double layer greenhouse covers. It was found that the U-value of PC, PVC, and HG was 9%, 4%, and 15% lower, respectively, than that for PE. In addition, by using double glazing a 34% reduction in heat loss was noted. For the given temperature U-value increases as wind speed increases. The slopes at the temperature differences of 20, 30, 40, and 50 °C, were approximately 0.3, 0.5, 0.7, and 0.9, respectively. The results agree with those put forward by other researchers. Hence, the presented model is reliable and can play a valuable role in future work on greenhouse energy modelling.
