Latex 没有在参考书目中显示我的参考文献

Question

我不知道为什么要使用参考书目，但我在文本和参考部分都看不到参考文献。这里是代码

\documentclass[a4paper, 12pt]{article}
\usepackage[UKenglish]{babel}
\usepackage[scale=0.75]{geometry}
\usepackage{xcolor}
\usepackage{datetime}
\usepackage{nomencl}
\makenomenclature
\usepackage{moreverb,url}

\newcommand\BibTeX{{\rmfamily B\kern-.05em 
\textsc{i\kern-.025em b}\kern-.08em
\kern-.1667em\lower.7ex\hbox{E}\kern-.125emX}}
\def\volumeyear{2016}
\usepackage{graphicx,subfigure}

\usepackage{nomencl}
\makenomenclature
\usepackage{setspace}

\usepackage{natbib}


\begin{document}
\cite{Mayer}, \cite{Oca} and \cite{IEA}

\section{Reference}

\bibliographystyle{SageH}
\bibliography{my_bibtex2}



\end{document}

下面是我的 bblatex

@article{Mayer,
title = "User behaviour regarding natural 
ventilation – state of the art and
research needs",
journal = "9th Nordic Symposium on Building 
Physics - NSB 2011",
volume = "3",
author = "Mayer"
}


@article{Oca,
title = "Effect of thermostat and window opening 
occupant behavior models on energy use in 
homes",
journal = "Building Simulation",
author = "Oca"
}

@article{IEA,
title =   " Reliability of Energy Efficient 
Building Retrofitting-",
author = "IEA"
}

在脚本文件的同一文件夹中，我有 SageH.bst

我不明白为什么我只看到问号而没有出现参考书目。

任何想法？
