Item Metadata only The potential for green roofs in sustainable urban drainage systemsDavis Michael, Joseph MaksUrban environments tend to lack the capacity to absorb water from precipitation. This is due to vegetated surfaces being replaced by impermeable ones, such as concrete, bitumen or similar. As a result problems can occur, where a period of heavy rainfall coincides with sudden increases in surface water runoff. This in turn can lead to a city’s sewerage system becoming overloaded. Sustainable Urban Drainage Systems (SUDS), are recognized worldwide as a successful manner by which to mitigate this phenomenon. One of the principal components of SUDS are permeable areas in an urban setting, which have the ability to absorb and retain rainfall that would otherwise flow as surface runoff. To date there has been little research into what the effect of a massive increase in green roofs would have for cities in Ecuador. As a developing country, it is not uncommon for cities’ sewerage systems to suffer collapse when faced with sudden rainfall peak loads. It is suggested in this paper, that instead of looking to implement costly sewerage expansion programs, it would be more cost effective to implement city scale green roof systems. The paper sets out to quantify the theoretical effect of such an initiativeItem Metadata only The potential for vertical gardens as evaporative coolers: An adaptation of the ‘Penman Monteith Equation’(2015-10) Davis Michael, Joseph Maks; Joseph Maks, Davis MichaelThis research paper investigates the use of vertical gardens as evaporative coolers. Vertical gardens play a key role in tackling the increasing challenges cities face, due to a rapidly growing urban environment with associated reductions in vegetation and an increase in the urban heat island effect. This paper aims to develop a mathematical model based on the FAO-56 Penman Monteith Equation that quantifies the effects of vertical gardens for evaporative cooling. The theoretical results are then compared with empirical findings for the experimental setup undertaken by Davis & Ramirez [1], which involved passing air behind the vertical garden (between the substrate and the surface). Correlation is observed when the computed value is at the lowest humidity (35%) of the three test runs (35%, 40%, and 45%). This either indicates that the vertical garden performs better than predicted by the mathematical model, or the relative humidity at the time when the measurements were made was in the region of 35% instead of the predicted 40%. This research indicates the potential for the FAO-56 Penman Monteith Equation to be integrated into a future design tool that facilitates the application of vertical gardens as evaporative coolers in building designs.Item Metadata only The recent legislation for eco-efficient design in Quito, Ecuador: a review and case study.

It is argued that the resolution for Quito is better suited to ecological building design parameters than using international certifications imported from abroad, such as LEED or BREEAM. The background of the parameters used for the resolution is explored in depth in this paper. The results of an international review workshop are then given, followed by a summary of the resolution being put into practice through a brief case study of the water systems proposed for a building designed under the legislation. Quito´s urban sprawl poses fundamental challenges from an ecological and economic perspective, but reverting this trend also provides a unique opportunity to plan, develop, build and manage a city that is simultaneously more ecologically and economically sustainable and more resilient. The present paper analyses how the New Resolution in Eco-efficient Design for Quito helps out in this task and becomes a versatile instrument, part of a broader tool, in contributing to the goals of eco-efficient design, providing incentives to the construction industry and reducing the number of private vehicles coming into the city. The paper concludes that it is possible to construct an effective eco-efficiency code aimed at reducing the environmental footprint of buildings whilst improving people’s quality of life. Furthermore, as the tool can be modified in future updates, research and better building practices are required to improve results and to adjust it to the ever-changing socio-economic contexts of the city. However, in order to be effective as the backbone of urban planning in Quito, the tool will need to be upgraded to the status of a municipal ordinance in future.
