Hines aims to meet and exceed the expectations of its clients, partnering to educate, design and execute a sustainable real estate strategy that is customized and appropriate to each client’s needs. Hines offers comprehensive development, renovation and property management services consistent with the highest standards of sustainability. Its estimated that the margin of performance efficency is 36.5%, which means that the total estimated annual glass house gas emissions avoided, in metric tons, is 521.720. Some of the keystones of the company are: Site selection and building orientation Cool or reflective roof High ceilings to maximize daylighting Efficient curtain walls Construction waste recycling Comprehensive preventive maintenance programs that identify repair and calibration needs Indoor air quality management and preventative maintenance program Harmonic distortion cancellation transformer Identification and execution of owner-appropriate energy improvement retrofit or upgrade opportunitie

Architectural description

It is a detached building with four stories, whose design is directly affected by the urban conditions such as building suitability, deviation from general line and height, as well as the topography and difference of level on the plot. The project watches the energy efficiency of the building. Each façade presents a different skin-like design, taking advantage of the northwest-southeast axis. The design is exhaustive in the search for materials to control solar reflectance while maintaining visual transparency, adopting constructive solutions with stressed fabric. In order to face the project and give the optimum proposal for the city and the future users, three main concepts have been considered: 1. - Volumetric and formal unity, with a unitary character through the compositions of facades and their relation with indoor and outdoor spaces. 2. - Rationality in function and construction, given its tertiary use for offices, plus designing all the constructive elements according to the new technologies and needs. 3.- Maximum use, with the appropriate design and layout.

Indoor Air quality

In order to guarantee comfort as well as the indoor air quality, Tripark Las Rozas includes a VRV system (variable cooling volume system, advanced climate system) together with a mechanical ventilation system. The ventilation system provides a constant air volume, 100% coming from the outside. There are ducts which take the supply air and take it to the roof equipment, so that the preassure is kept in comfort levels. Additionally, there is a secundary recirculation system that takes the air from each room and drive it to the VRV units, where it is processed with fresh air.

Urban environment

The building is placed in the surroundings of Madrid, as part of a business park in the municipality of Las Rozas. There are bus stops close by, which connect the building with the near by areas, the center of Las Rozas as well as with the metropolitan fabric of Madrid. The area where the Tripark is placed is not a closed business park with an only access. Both the residential and retail uses are separated from the business one, but relatively close. In spite of there are not parks o green areas in the inmediate surroundings, each building of the business park has its own green plot. Besides, the fields and vegetation typical of that region of Madrid can be found in just 200m distance from the Tripark building.
