Whatever the purpose, from detailed energy design to energy audits or HVAC system control strategies, building energy simulations can provide accurate results only if the energy model itself is accurately developed. The aim of this article is to review and analyze the current methodologies and approaches used when assessing building energy performance through simulations, focusing on the need for a calibrated model to enhance the simulation's credibility. This literature review identifies novel and practical methodologies, focusing on data collection, energy modeling approaches, simulation software, and calibration techniques. Although several studies have focused on building energy simulation, partially covering the topics addressed in this review, a detailed analysis and comparison of methods through normalized scores to derive possible recurrences and reproducible methods have not yet been presented.

Being able to understand data collected in a dynamic, interactive, and personalized way allows for better decisions to be made when optimizing and improving performance. Although its importance is known, there is a gap in the research regarding its design, choice criteria, and uses in the field of building energy consumption. Therefore, this review discusses the state-of-the-art of visualization techniques used in the field of energy performance, in particular by considering two types of building analysis: simulation and monitoring. Likewise, data visualizations are categorized according to goals, level of detail and target users. Visualization tools published in the scientific literature, as well as those currently used in the IoT platforms and visualization software, were analyzed. This overview can be used as a starting point when choosing the most efficient data visualization for a specific type of building energy analysis.

The objective of the research is to determine the socioeconomic viability of the Cohousing model in Lima as an alternative to the traditional real estate offer in the face of the current problem of dissatisfaction. Representative surveys have been used to identify the factors that influence the purchase intention of a home, focus groups were conducted to assess qualitative aspects of cohousing, presenting it as a competitive model, and a comparative economic-financial analysis was carried out. regarding a traditional multifamily housing project. The results of the research confirm the viability of the cohousing model in Lima by recognizing a public interested in its economic and social benefits. The model could open new opportunities for change and innovation for the real estate market,...

El objetivo de la investigación es determinar la viabilidad socioeconómica del modelo cohousing en Lima como alternativa a la oferta inmobiliaria tradicional frente a la problemática actual de insatisfacción. Se han empleado encuestas representativas para identificar los factores que influyen en la intención de compra de una vivienda, se realizaron focus group para valorar aspectos cualitativos del cohousing presentándolo como modelo competitivo y se llevó a cabo un análisis comparativo económico-financiero con respecto a un proyecto de vivienda multifamiliar tradicional. Los resultados de la investigación confirman la viabilidad del modelo cohousing en Lima al reconocer un público interesado en sus beneficios económicos y sociales. El modelo podría abrir nuevas oportunidades de cambio e innovación para el mercado inmobiliario, así como la posibilidad de formular nuevos programas de vivienda por parte de Estado.

Se estudiaron tres casos de estudio ubicados en dos zonas climáticas del Perú: Desértica (BW) y Mesoandina (Dwb). Los campamentos estudiados pertenecen a proyectos de Gran Minería y se encuentran ubicados dentro del área de influencia de la operación minera. Se emplearon evaluaciones objetivas y subjetivas: recojo de data in situ, simulaciones digitales, encuestas y entrevistas a los usuarios. La investigación ha permitido identificar las principales variables que influyen en el comportamiento térmico, acústico y lumínico interior y proponer recomen-daciones de diseño que puedan implementarse para mejorar el confort de los casos estudiados, así como de futuros proyectos con condiciones climáticas similares.

The study analyzes the behavior of three Peruvian mining camps in response to specific climatic and geographic variables with the objective of determining guidelines and criteria for bioclimatic architectural design, which seek to improve the quality of life, comfort and safety of the mining worker. The analysis was carried out through three study cases located in two climatic zones of Peru: Desert (BW) and Mesoandina (Dwb). The studied camps belong to large mining projects and are located within the area of influence of the mining operation. Objective and subjective evaluations were used: data collection in situ, digital simulations, surveys and user interviews. The research has made it possible to identify the main variables that influence the thermal, acoustic and lighting behavior and to propose design recommendations that can be implemented to improve the comfort of the studied cases, as well as future projects with similar climatic conditions.

En este contexto, y con el constante debate entre lo público y lo privado, es posible que las características inherentes del cohousing puedan tener vigencia insospechada en nuestro país, en donde el producto no es ajeno a nuestra realidad pero una afirmación de tradiciones existentes y reforzamiento de una vida urbana.
¿Qué sentido tiene la referencia al cohousing o la mención a la pérdida de noción de comunidad en un país como el Perú, donde la idea de comunidad, “comunidad urbana” o “comunidad campesina”, el AYNI, y otras políticas colaborativas siguen fuertemente vigentes?
Este artículo aspira a ser una introducción general sobre un modelo de vivienda que, respondiendo a las necesidades actuales, recupera muchas de las ventajas de las comunidades tradicionales.

The current economic crisis takes us totally unprepared to tackle the current social, political and economic challenges.
The need for living places which are also places of life, able to support common services, calls for new social structures that are meant not as an alternative to, but as an evolution from the traditional family.
The purpose aims to present a critical reflection on social housing, departing "from the needs in
order to get to the design principles" of the composition of a housing form based on sharing: Cohousing. This form of intentional community characterized by the integration of shared spaces for social interaction and common services that are based on self-government by consensus, which
attracts growing public interest and yet is still scarcely explored in a socio-architectural context, is
proposed as a model that supports the feeling of belonging to and responsibility towards the local community, while preserving the privacy and independence of each individual household.
After having analyzed Cohousing projects from around the world, a first selection of 149 casestudies was chosen and we carried out to select a second one with the 47 most representative projects. This methodology supports us to identify the most valued features, summarized in
application design principles in reference to the shape of types, the position of common services, of collective areas and the study of flexibility and techno-typological solutions, etc.
This paper aims to describe the meaning of Cohousing, studying the factors that have influenced and still influence its spread, the most common features and the methods and procedures for its workings. Based on experiences from the global landscape, comparing their different elements, we
have come to an experimental project proposal of a community with shared values, near Milan in which the theoretical principles define the design principles.
Cohousing is understood as a "project of sustainability" where it aims to create a parallel between the traditional components of sustainability: economic that means a home to a fair cost, social understood as an allocation of shared services and collective, environmental as a multi-approach of quality of dwelling.

The current economic crisis takes us totally unprepared to tackle the current social, political and economic challenges. The need for living places which are also places of life, able to support common services, calls for new social structures that are meant not as an alternative to, but as an evolution from the traditional nuclear family. The purpose of this work is to present a critical reflection about social housing, departing "from the needs in order to get to the design principles" of the composition of a housing form based on sharing: the Cohousing. This form of intentional community, that attracts growing public interest and yet is still scarcely explored in a socio-architectural context, characterized by the integration of shared spaces for social interaction and common services that are based on self-government by consensus, is proposed as a model that supports the feeling of belonging to and responsibility towards the local community, while preserving the privacy and independence of each individual household. The flexibility of the interior and exterior spaces arises as a design principle that is able to coexist with the process of participatory planning typical of the development of cohousing initiatives. This paper aims to describe the history and meaning of Cohousing, studying the factors that have influenced and influence its spread, the most common features and the methods and procedures for its workings. Based on experiences from the global landscape and comparing their different elements, we come to an experimental project proposal of an intentional community with shared values, in the city of Vimercate (MB).
