  • Guidelines on Energy Conserving Design of Buildings — 2020 Edition
    GUIDELINES ON ENERGY CONSERVING DESIGN OF BUILDINGS — 2020 EDITION Section I. Purpose 1.1 To encourage and promote the energy conserving design of buildings and their services to reduce the use of energy with due regard to the cost effectiveness, building function, and comfort, health, safety, and productivity of the occupants. 1.2 To prescribe guidelines and minimum requirements for the energy conserving design of new buildings and major renovation of existing buildings that fall and are covered under these guidelines and provide methods for determining compliance with the same to make the buildings always energy-efficient. Section Il. Definition of Terms 2. As used in these Guidelines, the following shall mean: Air— refers to any of the following: Ambient Air — air surrounding a building; the source of outdoor air brought into a building. Exhaust Air — air removed from a space and discharged to outside the building by means of mechanical or natural ventilation. Indoor Air— air in an enclosed occupiable space. Outdoor Air— ambient air that enters a building through a ventilation system, through intentional openings for natural ventilation, or by infiltration. Return Air— air removed from a space to be recirculated, or exhaust air. Supply Air — air delivered by mechanical or natural ventilation to a space and composed of any combination of outdoor air, recirculated air, or transfer air. Ventilation Air — supply air that is outdoor air plus any recirculated air that has been treated for the purpose of maintaining acceptable Indoor Air Quality. Air Conditioning — the process of treating air so as to control simultaneously its temperature, humidity, cleanliness, and distribution to meet the requirements of conditioned space.

    Episode 63 Smart Energy and Data The show notes: www.houseplanninghelp.com/63 Intro: Data is what we're talking about today. When I go to various different talks they will often reflect on data that has been collected, whether it's from moisture sensors or CO2 sensors so I did wonder whether it's something that I should be doing on my project, making sure that there is something useful coming out of it in terms of data. That probably means planning upfront so I just wanted to find out all about that. Recently I saw a talk on smart energy so I thought we'd tie this all together and see how we go with it. Doug King has a lot of experience in construction, particularly high performance buildings - which is what we like - and he's someone that I've been wanting to talk to for a while. I started by asking him for a little bit of background on his work. Doug: I started out as a physicist. I fell into the profession of building services engineering, out of curiosity, and then I spent the last 20 years thinking about how building services systems work together with building fabric, with the technology to control them and finally how human beings relate to all of that as a system in order to try and understand the key issues about optimisation, how to get these things working together properly rather than the building services systems fighting against the building fabric and the users not understanding what the hell is going on.

  • Veracode White Paper—The Internet of Things: Security Research Study
    Veracode White Paper – The Internet of Things: Security Research Study The Internet of Things: Security Research Study Veracode White Paper – The Internet of Things: Security Research Study Introduction As the Internet of Things (IoT) continues to gain traction and more connected devices come to market, security becomes a major concern. Businesses are increasingly being breached by attackers via vulnerable web-facing assets1; what is there to keep the same from happening to consumers? The short answer is nothing. Already, broad-reaching hacks of connected devices have been recorded2 and will continue to happen if manufacturers do not bolster their security efforts now. In this light, Veracode’s research team examined six Internet-connected consumer devices and found unsettling results. We investigated a selection of always-on consumer IoT devices to understand the security posture of each product. The result: product manufacturers weren’t focused enough on security and privacy, as a design priority, putting consumers at risk for an attack or physical intrusion. Our team performed a set of uniform tests across all devices and organized the findings into four different domains: user-facing cloud services, back-end cloud services, mobile application interface, and device debugging interfaces. The results showed that all but one device exhibited vulnerabilities across most categories. It’s clear there is a need to perform security reviews of device architecture and accompanying applications to minimize the risk to users. Further, the study

  • Task XIII Guide Book 6
    Version 6.0 IEA DSM Task XIII Project Guidebook November 2006 Copyright 2006 - IEA DRR LLC - Proprietary Information SECTION 6: DR TECHNOLOGIES 2 I. INTRODUCTION We all use tools to simplify our daily lives. Things such as the hammer, coffee maker, and computer are used to reduce the time it takes to complete a life’s daily chores. The demand response industry has also developed technologies that simplify the implementation and utilization of DR resources in the energy marketplace. In order for a DR resource to be useful in the energy market it must have the ability to react when needed and its response must be measurable. Tools and systems have been developed that help activate a DR asset (e.g. direct load control) and manage a DR asset portfolio (e.g. DR software products). These and other DR related technologies help the DR resource react to load reduction request and opportunities and they help provide the business process mechanisms that connect the resource to the energy marketplace. This chapter will explore how technology is being used in the demand response industry today. The objective of this section is to help the DR market participant identify technologies and systems that are used to make DR more effective in the energy marketplace from the perspective of the participating customer, the energy provider and the system operator. Improvement in communication and metering technologies has helped the demand response industry grow in recent years. In fact, some people have suggested that the demand response industry was made possible by the improvement and wide scale deployment of Internet communications in the late 1990s.
