Develop healthy building infrastructure for KTH LIVE-IN-LAB

Abstract [en]

The following master thesis is conducted on behalf of The Royal Institute ofTechnology and KTH Live-in Lab with the purpose of proposing a healthybuilding infrastructure for the KTH Live-in Lab. The Lab will serve as atestbed for products and services that can be tested and veried within anoptimal space that can simulate a real life usage of the tested products or services.Since the KTH Live-in Lab proposes to create a smart environment inorder to fulll its goal, this thesis proposes to design a system that measuresthe key factors that inuence the user's health while living in the building.The problem that this thesis is solving is that of understanding the relevantmetrics that aect the person living in the building, then identify andplace the sensors that can measure the health metrics and nally encapsulatethe result in a WSN, paying close attention to the topology and the communicationprotocols used, capable of monitoring and collecting all the relevantdata for further use.The most dicult part of the thesis is translating the health parametersinto the optimal quantiable metrics so that a developed system couldbecome a feasible solution for a home automation. The attempted way ofsolving this problem is through literature review of health studies in order tounderstand which are the quintessential parameters that should be measured.The system considers dierent health factors from 9 dierent domainsVentilation, Air Quality, Thermal Comfort, Moisture, Dust and Pests, Safetyand Security, Water Quality, Noise and Lighting and Views. Each of thesedomains will be analyzed and the best metrics for monitoring will be selected.The solution will be tailored on the KTH Live-in Lab as the sensor placementis done on the schematic of the Housing Design, of the Fall Semester 2017.In order to choose the optimal way to implement the wireless sensor network,several topologies and communication protocols are compared, the chosen onebeing ZigBee as protocol while the topology was separated in how sensorsare organized in every room which will be a mesh topology and how they areorganized in the whole building for which the chosen topology is the Two-tierhierarchical cluster topology. The system also proposes a security encryptionalgorithm for data protection and a way to evaluate the system based on thestandard of the WELL Building Institute.Future work will consist in implementing all the features that are designedin this paper while nding the perfect trade-o between the cost andtechnology accuracy when this project will be scaled for a whole apartmentbuilding.As a conclusion, there are certain variations that one can follow whenimplementing the designed system as the implementation will be a trade-obetween the quality of the equipment used which translates into the accuracyof the measurements and the nancial and social constraints. This thesisproposes a set of core elements that cannot be replaced in monitoring andalso provides approximations for other less common metrics.

Foljande masteravhandling har utfardats pa uppdrag av The Royal Instituteof Tecnology och KTH Live-in Lab med syftet att foresla en halsosambyggnadsinfrastruktur for KTH Live-in Lab. Labbet kommer att fungerasom en testbadd for produkter och tjanster som kan testas och verierasinom ett optimalt utrymme som kan simuleras till en verklig situation foranvandandet av de testade produkterna eller tjansterna. Eftersom att KTHLive-in Lab foreslar att skapa en smart miljo for att uppfylla sitt mal, foreslardenna avhandling att man designar ett system som mater huvudfaktorernasom paverkar anvandarens halsa under den tid som anvandaren vistas i byggnaden.Det problem som denna avhandling amnar losa ar att skapa en forstaelsefor de relevanta matvarden som paverkar den person som bor i byggnadenoch darefter identiera och placera de sensorer som kan mata halsomatvardenoch slutligen sammanfatta resultatet i en Tradlost sensornatverk, men ocksaagna stor uppmarksamhet till topologin och kommunikationsprotokollen somanvants, som ar kapabla att monitorera och samla all relevant data for vidareanvandning.Det svaraste med denna avhandling ar att oversatta halsoparametrarnatill optimala kvantierbara matvarden sa att ett utvecklat system kan bli engenomforbar losning for en hemautomatisering. Tillvagagangssattet for attlosa detta problem ar genom att granska litteratur om halsostudier for attforsta vilka parametrar som ar vasentliga och som bor matas.Systemet tar hansyn till olika halsofaktorer fran 9 olika domaner; Ventilation,Luftkvalitet, Temperaturkomfort, Fukt, Damm, Sakerhet, Vattenkvalitet,Ljud och Ljus och Syn. Var och en av dessa domaner kommer att analyserasoch de basta matvardena for monitorering kommer att bli utvalda. Losningenkommer att skraddarsys pa KTH Live-in Lab medan sensorplaceringen arutfardad pa schematik av husets design, hostterminen 2017. For att kunnavalja det mest optimala sattet att implementera det tradlosa sensornatverkethar era topologier och kommunikationsprotokoll jamforts. Genom att goradetta har ZigBee valts som kommunikationsprotokoll medan topologin hardelats upp i hur sensorer ar organiserade i varje rum, vilket kommer att varaen "mesh"-topologi, och hur de ar organiserade i hela byggnaden och darav arden valda topologin"Two-tier hierarchial cluster topology". Systemet foreslarocksa en sakerhetskrypteringsalgoritm som dataskydd och som ett satt attutvardera systemen som ar baserade pa standarden av "the WELL BulidingInsitute".Framtida arbete kommer att innefatta implementering av alla funktionersom ar designade i denna avhandling medan det perfekta utbytet mellankostnad och teknologiprecision hittas da detta projekt kommer att skalas foren hel lagenhetsbyggnad.Som slutsats, nns vissa variationer som en kan folja vid implementeringav det designade systemet da implementationen kommer att vara ett utbytemellan kvalitet av utrustningen som anvands som oversatts i noggrannhetav matningar och nansiella och sociala begransningar. Denna avhandlingforeslar ett set av karnelement som inte kan bytas ut i monitorering och somocksa bistar med approximationer for andra mindre vanliga matvarden.
