A requalificação de edifícios altos residencias no centro da cidade de São Paulo: em busca de qualidade ambiental / The refurbishment of tall buildings in the center of city of São Paulo: looking of environmental performanceUzum, Monica dos Santos Dolce 15 April 2011 (has links)
O objeto da pesquisa é a requalificação de edifícios altos residenciais acima de 15 pavimentos, situados no centro da cidade de São Paulo e construídos entre 1930 e 1964, sendo a maioria de um cômodo, conhecidos como kitchenettes, com ênfase nas possibilidades de renovação arquitetônica e requalificação tecnológica para sua reocupação, visando as questões de desempenho ambiental. No momento atual das cidades modernas, um número significativo de edifícios de médio e grande porte, encontrados em diferentes partes do mundo, inevitavelmente necessitam e recorrem a projetos de requalificação arquitetônica e tecnológica. É verificado que o centro da cidade de São Paulo possui um estoque edificado obsoleto e uma grande potencialidade para receber novas edificações, além de requalificar as existentes. Com isso, o objetivo principal desta pesquisa é qualificar o edifício existente provendo conforto ergonômico, térmico, luminoso e acústico, mediante padrões e critérios pré-estabelecidos de desempenho ambiental. Como resultado é verificado que existem possibilidades de intervenção que permite ao edifício alcançar melhor desempenho ambiental, com um redesenho das unidades a fim de criar apartamentos de um e dois dormitórios, melhorando o aproveitamento da ventilação e iluminação natural e inserindo barreiras contra o ruído urbano nas fachadas. / The object of this research is the refurbishment of tall buildings over 15 floors, situated in the center of city of São Paulo and built between 1930 and 1964, most of them with just one bedroom, known as kitchenetts, with emphasis on opportunities of architectural upgraded and technological refurbishment for them reoccupation, targeting the issues of environmental performance. In the actual moment of modern cities, a significant number of medium and big buildings, found in different parts of the world, inevitably need and require projects of architectural and technological refurbishment. It is verified that São Paulo downtown has a built obsolete inventory and it is prone to receive new buildings, besides the refurbishment of existing ones. Thus, the main aim of this research is to refurbish the actual building, providing it with ergonomic, thermal, light and sound comfort through standards and pre-determined criteria of environmental performance.

Interior Damage of Residential Building Due to Wind-Driven Rain IntrusionRaji, Farzaneh 01 November 2018 (has links)
This research aims to experimentally investigate the interior damage in residential buildings caused by rainwater intrusion during hurricane events. The first step, to experimentally evaluate the wind-driven rain effects on the building’s interior, is to accurately simulate the rain field associated with the hurricane. The wind-driven rain simulation was performed at the 12-fan Wall of Wind Experimental Facility at Florida International University. The characteristic of the simulated rain field was compared to a target characteristic obtained from the recorded data from past hurricanes to validate the simulation. In the next step, the large-scale models were subjected to the simulated rain field to observe the water propagation inside the models. The gable and hip roof models were prepared with three different exterior damage conditions, including the light damage state, minor damage state, and moderate damage state, to investigate the effect of envelope openings on the water propagation path. Each model was tested at three wind angles of 0˚, 45˚ and 90˚ to assess the effects of wind direction. The interior of the models was divided into 6 different room compartments separated by partition walls, as well as 6 different attic compartments divided by short divider pieces. Finally, the results were used to evaluate the share of each interior component from the total amount of water that intrudes into the building. The last phase of the research concentrated on the experimental evaluation of the sustained damage by partition walls subjected to water intrusion. The full-scale model was subjected to the simulated rain field at the Wall of Wind Experimental Facility test section. The interior of the model was built to simulate the actual interior of a residential building. The experimental results were used to evaluate the sustained damage by the partition. This research made a great step forward in clarifying the mechanism of interior damage sustained in residential buildings due to rain intrusion during hurricanes. Most important, the results can be used in Hurricane Loss Models to predict the sustained damage on residential buildings at different hurricane hazard levels.

Operational and Technological Peak Load Shifting Strategies for Residential BuildingsJanuary 2016 (has links)
abstract: Residential air conditioning systems represent a critical load for many electric
utilities, especially for those who serve customers in hot climates. In hot and dry
climates, in particular, the cooling load is usually relatively low during night hours and
early mornings and hits its maximum in the late afternoon. If electric loads could be
shifted from peak hours (e.g., late afternoon) to off-peak hours (e.g., late morning), not
only would building operation costs decrease, the need to run peaker plants, which
typically use more fossil fuels than non-peaker plants, would also decrease. Thus, shifting
electricity consumption from peak to off-peak hours promotes economic and
environmental savings. Operational and technological strategies can reduce the load
during peak hours by shifting cooling operation from on-peak hours to off-peak hours.
Although operational peak load shifting strategies such as precooling may require
mechanical cooling (e.g., in climates like Phoenix, Arizona), this cooling is less
expensive than on-peak cooling due to demand charges or time-based price plans.
Precooling is an operational shift, rather than a technological one, and is thus widely
accessible to utilities’ customer base. This dissertation compares the effects of different
precooling strategies in a Phoenix-based utility’s residential customer market and
assesses the impact of technological enhancements (e.g., energy efficiency measures and
solar photovoltaic system) on the performance of precooling. This dissertation focuses on
the operational and technological peak load shifting strategies that are feasible for
residential buildings and discusses the advantages of each in terms of peak energy
savings and residential electricity cost savings. / Dissertation/Thesis / Doctoral Dissertation Civil Engineering 2016

Návratnost investic spojených s výstavbou bytového domu v Hradci Králové a v Brně. / The return on investment associated with construction of a residential building in the cities of Hradec Králové and BrnoLebrušková, Petra January 2015 (has links)
This diploma thesis aims at the return on investment associated with construction of a residential building in the cities of Hradec Králové and Brno. As a first step, we calculate the investment amount needed to construct the building and set the rent for each apartment. Next, we determine whether discounted net rent from all residential units will cover construction costs. Investment payback period will be then assessed. We also calculate market value for each unit and a summarized value for selling all the units. Finally, we determine which of the following scenarios leads to higher profits – selling the residential building unit by unit versus renting the units. This evaluation will also take into account the results difference based on chosen city.

Energy Analytics for Eco-feedback Design in Multi-family Residential BuildingsSang Woo Ham (11185884) 27 July 2021 (has links)
<p>The residential sector is responsible for
approximately 21% of the total energy use in the U.S. As a result, there have
been various programs and studies aiming to reduce energy consumption and
utility burden on individual households. Among various energy efficiency
strategies, behavior-based approaches have received considerable attention
because they significantly affect operational energy consumption without requiring
building upgrades. For example, up to 30% of heating and cooling energy savings
can be achieved by having an efficient temperature setpoint schedule. Such
approaches can be particularly beneficial for multi-family residential
buildings because 88% of their residents are renters paying their own utility
bills without being allowed to upgrade their housing unit.</p>
<p>In this context, eco-feedback has emerged as an
approach to motivate residents to reduce energy use by providing information
(feedback) on human behavior and environmental impact. This research has gained
significant attention with the development of new smart home technology such as
smart thermostats and home energy management systems. Research on the design of
effective eco-feedback focuses on how to motivate residents to change their
behavior by identifying and notifying implementable actions in a timely manner
via energy analytics such as energy prediction models, energy disaggregation,
etc.</p>
<p>However, unit-level energy analytics pose significant
challenges in multi-family residential buildings tasks due to the inter-unit
heat transfer, unobserved variables (e.g., infiltration, human body heat gain,
etc.), and limited data availability from the existing infrastructure (i.e.,
smart thermostats and smart meters). Furthermore, real-time model inference can
facilitate up-to-date eco-feedback without a whole year of data to train
models. To tackle the aforementioned challenges, three new modeling approaches
for energy analytics have been proposed in this Thesis is developed based on
the data collected from WiFi-enabled smart thermostats and power meters in a multi-family
residential building in IN, U.S.</p>
<p>First, this Thesis presents a unit-level data-driven
modeling approach to normalize heating and cooling (HC) energy usage in
multi-family residential buildings. The proposed modeling approach provides
normalized groups of units that have similar building characteristics to
provide the relative evaluation of energy-related behaviors. The
physics-informed approach begins from a heat balance equation to derive a
linear regression model, and a Bayesian mixture model is used to identify
normalized groups in consideration of the inter-unit heat transfer and
unobserved variables. The probabilistic
approach incorporates unit- and season-specific prior information and
sequential Bayesian updating of model parameters when new data is available.
The model finds distinct normalized HC energy use groups in different seasons
and provides more accurate rankings compared to the case without normalization.</p>
<p>Second, this Thesis presents a real-time modeling
approach to predict the HC energy consumption of individual units in a
multi-family residential building. The model has a state-space structure to
capture the building thermal dynamics, includes the setpoint schedule as an
input, and incorporates real-time state filtering and parameter learning to
consider uncertainties from unobserved boundary conditions (e.g., temperatures
of adjacent spaces) and unobserved disturbances (i.e., window opening,
infiltration, etc.). Through this real-time form, the model does not need to be
re-trained for different seasons. The results show that the median power
prediction of the model deviates less than 3.1% from measurements while the
model learns seasonal parameters such as the cooling efficiency coefficient
through sequential Bayesian update.</p>
Finally, this Thesis presents
a scalable and practical HC energy disaggregation model that is designed to be developed
using data from smart meters and smart thermostats available in current advanced
metering infrastructure (AMI) in typical residential houses without additional
sensors. The model incorporates sequential Bayesian update whenever a new
operation type is observed to learn seasonal parameters without long-term data
for training. Also, it allows modeling the skewed characteristics of HC and
non-HC power data. The results show that the model successfully predicts
disaggregated HC power from 15-min interval data, and it shows less than 12% of
error in weekly HC energy consumption. Finally, the model is able to learn
seasonal parameters via sequential Bayesian update and gives good prediction
results in different seasons.
